RESUMO
INTRODUCTION: Virtual simulation (VS) can be an effective learning strategy in the context of nursing education on cardiovascular disease; however, its use in teaching cardiology in nursing is less studied. The objective of this scoping review is to map the use of VS for teaching cardiology in nursing. METHODS AND ANALYSIS: This scoping review will be conducted according to the Joanna Briggs Institute methods, and the results will be reported according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist. Eight databases will be searched: MEDLINE (NCBI/PubMed), Cumulative Index to Nursing and Allied Health Literature, Web of Science, Latin American and Caribbean Literature in Health Sciences, Spanish Bibliographic Index of Health Sciences, Database of Nursing, EMBASE and Google Scholar from inception to 31 July 2024. This study will include any existing peer-reviewed literature and grey literature. There will be no time or language restrictions. Two reviewers will screen and select the articles independently, and when there are differences, they will be resolved with a third opinion. When appropriate, broad themes and categories derived from the review questions will be accompanied by other illustrative formats (eg, tables or graphs, word clouds and infographics). ETHICS AND DISSEMINATION: This research project does not require ethical committee approval. The study is part of a cooperative research project between researchers from the Federal University of Piauí, Northeast of Brazil, and Queen's University, Ontario, Canada, to develop and seek evidence of content validity of a VS game about valvular heart disease. The protocol and review will be published in peer-reviewed journals. REGISTRATION DETAILS: Open Science Framework (https://doi.org/10.17605/OSF.IO/S3UMH).

Objective: Assessing subclinical atherosclerosis (sAT) is crucial for preventing cardiovascular disease. The Mediterranean diet is considered the gold standard for cardiovascular protection, but cultural and economic barriers can hinder adherence to it. The prudent dietary pattern (DP) has been associated with protective effects against chronic diseases. However, its impact on primary cardiovascular prevention remains uncertain. This study examined adherence to various DPs and their effect on sAT, measured by total carotid plaque area (TPA). Methods: This cross-sectional study included 116 adults enrolled in a cardiovascular prevention program. Demographic, clinical, laboratory, and TPA data were collected. Adherence to DPs was assessed using a food frequency questionnaire. Participants were categorized according to their adherence to 4 mutually exclusive DPs: prudent, traditional, sweet, and mixed. Generalized linear models were used to assess the effect of DPs on TPA, adjusting for relevant cardiovascular variables. Results: The traditional, sweet, and mixed DPs were associated with higher TPA values than the prudent DP, with medians (interquartile range) of 27 (99), 39 (49), 27.5 (58), and 0 (36) mm2, respectively. Gamma regression analysis found that the beta exponents for the traditional, sweet, and mixed DPs versus the prudent DP were 3.78 (p=0.046); 3.73 (p=0.013), and 2.20 (p=0.072), respectively. Systolic blood pressure values were higher for the sweet and mixed DPs than for the prudent DP (133.9±11.7; 132.5±13.9 and 122.7±8.8 mmHg, respectively; p<0.05). Conclusion: These findings underscore the importance of additional research and targeted interventions to promote healthier DPs to promote improvements in cardiovascular health.
RESUMO
INTRODUCTION: Nattokinase (NK) is the primary ingredient of natto, a traditional Asian food made from fermented soybean by Bacillus subtilis natto. Studies have shown that natto reduces the risk of cardiovascular disease (CVD) mortality due to its fibrinolytic and antithrombotic properties. A new field of studies also demonstrates that NK can mitigate molecular pathways related to inflammation and oxidative stress and can be considered an adjuvant strategy for use in many non-communicable diseases (NCDs). This paper is a narrative review of the literature. A search was conducted in PubMed and ScienceDirect up to July 2024. AREAS COVERED: This review discusses the possible effects of NK on mitigating the common complications of NCDs, such as inflammation and oxidative stress. In addition, it provides an update on the most addressed areas related to NK's fibrinolytic and antithrombotic activities. EXPERT OPINION: Due to the fibrinolytic and antithrombotic activity of nattokinase, and more recently added to the anti-inflammatory and antioxidant effects, this enzyme can be used as a new adjuvant therapeutic strategy to mitigate inflammation and oxidative stress in NCDs, including CVD.
RESUMO
Background: Hispanics/Latinos of Dominican background living in United States (US) have the highest hypertension prevalence compared with other Hispanic/Latino persons. Objective: To understand cardiovascular health among Dominicans, we evaluated hypertension prevalence and risk factors among Dominicans from the US and Dominican Republic (DR) using data from Hispanic Community Health Study/ Study of Latinos [HCHS/SOL] and the Prevalencia de Hipertension Arterial y Factores de Riesgo Cardiovasculares en la República Dominicana al 2017 (ENPREFAR-HAS 17) study. Methods: Hypertension was defined as blood pressure ≥140/90 mmHg, self-reported hypertension, or antihypertensive use. Exposures included sociodemographic/socioeconomic, clinical, and lifestyle/behavioral characteristics. Weighted generalized linear models were used to estimate associations between study characteristics and hypertension prevalence (PR = prevalence ratio), age-and-sex adjusted. HCHS/SOL (n = 1,473, US Dominicans; mean age 41 years, 60.4% female) was analyzed with survey procedures, while ENPREFAR-HAS 17 (n = 2,015 DR Dominicans; mean age 40 years, 50.3% female) was analyzed with statistical analyses for simple random sampling. Results: Hypertension prevalence was 30.5% and 26.9% for DR and US Dominicans, respectively. Hypertension control was low in both cohorts (36.0% DR, 35.0% US). Alcohol use among DR Dominicans was inversely associated with hypertension prevalence (PRDR = 0.8) with no association among US Dominicans. In both settings, diabetes (PRDR = 1.4; PRUS = 1.4) and obesity (PRDR = 1.8; PRUS = 2.0) were associated with greater hypertension prevalence in Hispanics/Latinos of Dominican background. Physical activity was lower among US Dominicans (PR = 0.80) but higher among DR Dominicans (PR = 1.16); all p < 0.05. Conclusions: Variations in social, lifestyle/behavioral, and clinical characteristics associated with hypertension among Dominicans in the US and DR were identified, suggesting that social context and cultural factors matter among immigrant populations.

Cardiovascular disease (CVD) poses a significant health burden, particularly among individuals of low socioeconomic status (SES) in low- and middle-income countries (LMICs). This study evaluates the clinical effectiveness of cardiac rehabilitation (CR) in addressing CVD outcomes among very low-SES patients in Colombia. Data from participants enrolled in a CR program in Colombia between 2022 and 2023 were analyzed retrospectively. Measures included heart-healthy behaviors, physical/psychological outcomes, and quality of life assessed at 18, 36, and 60 sessions. Significant improvements were observed in exercise capacity, psychological well-being, and quality of life metrics throughout the CR program. However, barriers to CR attendance and the critical need for expanded program availability remain evident, particularly in LMIC settings like Colombia. In conclusion, structured CR programs demonstrate substantial benefits for very low-SES individuals in a LMIC country, highlighting the urgent need for increased program accessibility and equitable healthcare provision to optimize cardiovascular health outcomes.
RESUMO
OBJECTIVE: To translate data relating childhood cardiovascular (CV) risk factors and adult CV disease and type 2 diabetes mellitus (T2DM) to clinically actionable values. STUDY DESIGN: This was a prospective observational study (n = 38â589) in the International Childhood Cardiovascular Cohort Consortium. Children at age 3 through 19 years were enrolled in the 1970s and 1980s and followed for more than 30 years. Five childhood CV risk factors (smoking, body mass index [BMI], systolic blood pressure, triglycerides, and total cholesterol) were related to adult CV events. Secondary analyses in a subset included low-density lipoprotein cholesterol, high-density lipoprotein cholesterol, glucose, and insulin level. Age- and sex-specific z scores were calculated for each risk factor, and a combined-risk z score was calculated by averaging z scores for the 5 key CV risk factors. Risk factor z scores were back-transformed to natural units for clinical interpretation, with hazard ratios for adult CV events presented in color-coded tables (green: no increased risk; orange: 1.4 to <2.0-fold increased risk; red: at least doubling of risk). Risk levels for development of adult T2DM on the basis of BMI, glucose, and insulin were similarly calculated and presented. RESULTS: Increased risk for CV events was observed at levels lower than currently defined abnormal clinical thresholds except for TC. Doubling of risk was observed at high normal levels just below the clinical cut point for abnormality. Risk for adult T2DM began at levels of BMI and glucose currently considered normal. CONCLUSIONS: On the basis of data showing significant relationships between childhood CV risk factors and adult CV events and T2DM, this study shows that risk in childhood begins below levels currently considered normal.
RESUMO
Objective: This article aims to assess the adherence level to second-line therapy for cardiovascular prevention in a tertiary hospital in Mexico City and identify key barriers to adequate pharmacological adherence. Methods: A single-center prospective cross-sectional study was conducted between August 2018 and February 2020. Sociodemographic data were collected, and the Morisky medication adherence scale was performed. Directed interviews during medical consultations were also conducted to determine reasons for non-adherence. Results: Showed that out of 991 patients included with a median age of 65 (58.72) years, 70.3% exhibited inadequate adherence, with forgetfulness being the most common reason (55.4%). Patients receiving combined therapy with coronary revascularization showed higher adherence compared to those on optimal medical therapy alone. Low educational level (OR 1.68, IC 95% 1.23-2.23, p = 0.0001) and the use of optimal medical therapy alone (OR 1.2, I 95% 1.11-2.007 p = 0.007) were identified as predictors of poor adherence. Conclusion: Among patients with ischemic heart disease and pharmacological therapy for secondary prevention, inadequate adherence is observed in 70% of cases. Factors associated with poor pharmacological adherence were low educational level and prescription of medical therapy without revascularization.
Objetivo: Determinar el nivel de adherencia a la terapia secundaria de prevención cardiovascular en un hospital terciario de la Ciudad de México e identificar las barreras que contribuyen a la inadecuada adherencia farmacológica. Métodos: Se realizó un estudio transversal entre agosto de 2018 y febrero de 2020. Se obtuvieron los datos sociodemográficos, la escala de adherencia a la medicación de Morisky, y se realizó una entrevista sobre las razones de la no adherencia. Resultados: 991 pacientes fueron incluidos con una mediana de edad de 65 (58,72) años. La adherencia inadecuada fue de 70.3%, siendo el olvido la causa más frecuente (55.4%). Aquellos pacientes en terapia farmacológica combinada con revascularización coronaria fueron más adherentes que aquellos en terapia médica óptima. El bajo nivel educativo (OR 1.68, IC95%1.23-2.3, p = 0.001) y el uso de tratamiento médico óptimo solo (OR 1.52, IC95%1.11-2.07, p = 0.007) fueron predictores de mala adherencia. Conclusión: En pacientes con cardiopatia isquemica y terapia farmacológica para prevención secundaria se observa adherencia inadecuada en 70%. Los factores asociados a mala adherencia farmacológica fueron el bajo nivel educativo y la prescripción de tratamiento médico sin revascularización.
RESUMO
OBJECTIVES: To assess whether genotype-guided selection of oral antiplatelet drugs using a clinical decision support (CDS) algorithm reduces the rate of major adverse cardiovascular and cerebrovascular events (MACCEs) among Caribbean Hispanic patients, after 6 months. DESIGN: An open-label, multicentre, non-randomised clinical trial. SETTING: Eight secondary and tertiary care hospitals (public and private) in Puerto Rico. PARTICIPANTS: 300 Caribbean Hispanic patients on clopidogrel, both genders, underwent percutaneous coronary intervention (PCI) for acute coronary syndromes, stable ischaemic heart disease and documented extracardiac vascular diseases. INTERVENTIONS: Patients were separated into standard-of-care (SoC) and genotype-guided (pharmacogenetic (PGx)-CDS) groups (150 each) and stratified by risk scores. Risk scores were calculated based on a previously developed CDS risk prediction algorithm designed to make actionable treatment recommendations for each patient. Individual platelet function, genotypes, clinical and demographic data were included. Ticagrelor was recommended for patients with a high-risk score ≥2 in the PGx-CDS group only, the rest were kept or de-escalated to clopidogrel. The intervention took place within 3-5 days after PCI. Adherence medication score was also measured. PRIMARY AND SECONDARY OUTCOMES: The occurrence rate of MACCEs (primary) and bleeding episodes (secondary). Statistical associations between patient time free of events and predictor variables (ie, treatment groups, risk scores) were tested using Kaplan-Meier survival analyses and Cox proportional-hazards regression models. RESULTS: The genotype-guided group had a clinically lower but not significantly different risk of MACCEs compared with the SoC group (8.7% vs 10.7%, p=0.56; HR=0.56). Among high-risk score patients, genotype-driven guidance of antiplatelet therapy showed superiority over SoC in reducing MACCE incidence 6 months postcoronary stenting (adjusted HR=0.104; p< 0.0001). CONCLUSIONS: The potential benefit of implementing our PGx-CDS algorithm to significantly reduce the incidence rate of MACCEs in post-PCI Caribbean Hispanic patients on clopidogrel was observed exclusively among high-risk patients, with apparently no evident effect in other patient groups. TRIAL REGISTRATION NUMBER: NCT03419325.

Cardiovascular disease and cardiovascular risk factors are global healthcare problems, given their high prevalence and the recognized low rates of adequate control despite the abundant body of evidence on different therapeutic options. The World Heart Federation has scrutinized the reasons for poor control of cardiovascular risk factors. Among these reasons, patients' poor adherence to treatment regimens as well as limited rates of evidence-based therapy prescription from healthcare providers play a substantial role in the challenge of cardiovascular risk management. Polypills are fixed-dose combinations including two or more active drugs, from different pharmacological classes, combined in a single dosage form. Polypills were designed to simplify the clinical management of pharmacotherapy and increase adherence to treatment. From this perspective, we discuss the current literature on the use of polypills in the primary and secondary prevention of cardiovascular disease as well as future challenges and the potentials of this treatment strategy.
RESUMO
Background: Comprehensive research evidence is lacking on the role of ultra-processed foods (UPF) in the relationship between the consumption of plant-sourced foods and their impact on cardiovascular disease (CVD) outcomes. This study aims to assess CVD risk associated with the dietary contribution of food groups that consider both plant or animal origin and food processing categories, within a large cohort of British adults. Methods: Data from the UK Biobank participants (40-69 y) who completed at least two 24-h dietary recalls between 2009 and 2012 (n = 126,842; median follow-up: 9 y), with subsequent data linkage to hospital and mortality records, were used. Food groups were classified as either plant-sourced or non-plant/animal-sourced foods. These groups were further divided into non-UPF and UPF, and expressed as a percentage of total energy intake. Findings: Every 10 percentage points increase in plant-sourced non-UPF consumption was associated with a 7% lower risk of CVD (95% CI 0.91-0.95) and a 13% lower risk of CVD mortality (0.80-0.94). Conversely, plant-sourced UPF consumption was associated with a 5% increased risk (1.03-1.07) and a 12% higher mortality (1.05-1.20). The contribution of all UPF was linked to higher CVD risk and mortality, and no evidence for an association between contribution of all plant-sourced foods and CVD incidence and mortality was observed. Interpretation: The dietary contribution of plant-sourced non-UPF inversely linked to CVD risk, while plant-sourced UPF contribution showed a positive association. Recognizing the role of food processing is crucial for favourable CVD outcomes, even in plant-sourced diets. Funding: World Cancer Research Fund.
RESUMO
BACKGROUND: The survival of pediatric chronic kidney disease (CKD) patients has improved in recent decades due to advances in dialysis and transplantation. However, cardiovascular disease (CVD) emerges as the main cause of mortality in patients with CKD. OBJECTIVES: To estimate cardiovascular risk in children with CKD at least 1 year after kidney transplantation. In addition, the possible association of cardiovascular risk with classic biochemical markers and potential new markers of this outcome was investigated. METHODS: An observational ambidirectional (retrospective capture of risk factors and prospective study of outcomes) research including 75 patients who underwent renal transplant between 2003 and 2013 with postoperative follow-up of at least 1 year was conducted. The outcome variables adopted were the LV mass Z-score and the presence of coronary calcification on computed tomography using calcium Agatston score. RESULT: Only one patient had an elevated calcium score, and three children (4%) had an LV mass Z-score ≥ 2.0. After multivariable analysis, only gender, serum triglyceride, and serum renalase concentration remained significantly associated with LV mass. CONCLUSION: The low incidence of cardiovascular changes in the population studied confirms the benefit of transplantation for the cardiovascular health of children. Nevertheless, long-term follow-up of these patients is recommended, given the limited duration of kidney function provided by transplantation and the high likelihood of further dialysis and kidney transplants being required in these children.

OBJECTIVES: Cardiovascular diseases (CVDs) are the leading causes of global mortality. Modifiable behavioural and metabolic risk factors significantly contribute to the burden of CVD. Given the vast socio-demographic and health outcome heterogeneity in Latin America, similar southern Latin American countries (Argentina, Chile, and Uruguay) were analysed as a distinct group to describe the CVD death rates related to metabolic and behavioural risk factors. STUDY DESIGN: An ecological study was performed using data from the Global Burden of Disease Study 2019. METHODS: Metabolic and behavioural risk factors-related CVD death were examined by analysing age-standardised rates per 100,000 individuals in the three countries between 1990 and 2019. RESULTS: While exposure to behavioural risk is decreasing, an upwards trend was observed in metabolic risks. Among the assessed risk factors, metabolic factors emerged as the primary contributors to deaths. High fasting plasma glucose exhibited a remarkable increase in relative importance across most studied contexts. Dietary risks stood out among behavioural factors due to their complexity and substantial changes observed. Although mortality rates have declined for overall CVD, peripheral artery disease mortality is rising. CONCLUSION: Modifiable behavioural and metabolic risk factors significantly influence CVD mortality in Southern Latin America. Despite the increasing exposure to metabolic risks, advancements in prevention and treatment are evidenced in the decline of mortality rates for most CVD. These findings emphasise the need for targeted interventions and comprehensive strategies to address their impact on cardiovascular health, advocating for healthy lifestyle behaviours to mitigate the progression and CVD development.

Despite the predisposition to bleeding, patients with immune thrombocytopenia (ITP) may also have an increased risk of arterial and venous thrombosis, which can contribute to significant morbidity. The risk of thrombosis increases with age and the presence of cardiovascular risk factors. This narrative review explores the multifactorial nature of thrombosis in ITP, focusing on new pathological mechanisms, emerging evidence on the association between established treatments and thrombotic risk, the role of novel treatment approaches, and the challenges in assessing the balance between bleeding and thrombosis in ITP. The review also explores the challenges in managing acute thrombotic events in ITP, since the platelet count does not always reliably predict either the risk of bleeding or thrombosis and antithrombotic strategies lack specific guidelines for ITP. Notably, second-line therapeutic options, such as splenectomy and thrombopoietin receptor agonists (TPO-RAs), exhibit an increased risk of thrombosis especially in older individuals or those with multiple thrombotic risk factors or previous thrombosis, emphasizing the importance of careful risk assessment before treatment selection. In this context, it is important to consider second-line therapies such as rituximab and other immunosuppressive agents, dapsone and fostamatinib, which are not associated with increased thrombotic risk. In particular, fostamatinib, an oral spleen tyrosine kinase inhibitor, has promisingly low thrombotic risk. During the current era of the emergence of several novel ITP therapies that do not pose additional risks for thrombosis, it is critical to outline evidence-based strategies for the prevention and treatment of thrombosis in ITP patients.

The intricate interplay between the gut microbiota and polyphenols has emerged as a captivating frontier in understanding and potentially harnessing the therapeutic potential of these bioactive compounds. Phenolic compounds, renowned for their antioxidant, anti-inflammatory, antidiabetic, and anticancer properties, are subject to intricate transformations within the gut milieu, where the diverse microbial ecosystem exerts profound effects on their metabolism and bioavailability. Conversely, polyphenols exhibit a remarkable capacity to modulate the composition and activity of the gut microbiota, fostering a bidirectional relationship that extends beyond mere nutrient processing. This symbiotic interaction holds significant implications for human health, particularly in cardiometabolic diseases such as diabetes mellitus, metabolic-dysfunction-associated steatotic liver disease, and cardiovascular disease. Through a comprehensive exploration of molecular interactions, this narrative review elucidates the reciprocal dynamics between the gut microbiota and polyphenols, unveiling novel avenues for therapeutic intervention in cardiometabolic disorders. By unravelling the intricate cross-talk between these two entities, this review underscores the multifaceted roles of polyphenols in overall health and the pivotal role of gut microbiota modulation as a promising therapeutic strategy in mitigating the burden of cardiometabolic diseases.

Background: The objective of this research is to evaluate the efficacy and safety of drugs in the residual risk in any of its three components: lipid, inflammatory and thrombotic risk. Methods: A systematic review was conducted of randomized clinical trials that included as a primary outcome, at least one of the conditions related to atherosclerotic cardiovascular disease. The databases used were PUBMED/MEDLINE, Scopus and ClinicalTrials.gov. The risk of bias of the studies was assessed using the Risk of Bias 2 tool. Results: and discussion: 18 studies were included in the analysis. Half of the studies had low risk of bias or some concerns. Several drugs were effective in reducing the primary outcome: ethyl eicosapentaenoeic acid (17.2 % E-EPA versus 22 % placebo HR: 0.75; 95 % CI 0.68-0.83; p < 0.001), colchicine in stable coronary artery disease (6.8 % vs placebo 9.6 %, HR 0.59, 95 % CI 0.57-0.83; p < 0.001), Canakinumab (150 mg vs placebo ARR 15 %, HR 0.85, 95 % CI 0.74-0.98; p = 0.021) and Rivaroxaban with Aspirin in stable atherosclerotic disease (4.1 % versus aspirin 5.4 %, HR 0.76, 95 % CI 0.66-0.86, P < 0.001). Serious adverse events did not differ between study groups, except for a higher rate of bleeding with the use of combination antithrombotic therapy. Conclusion: The residual risk can be reduced through the use of different drugs that act by modifying atherogenic lipid levels, modulating inflammatory pathways and the risk of thrombosis, with an acceptable safety profile in most studies.
RESUMO
Worldwide, as well as in Mexico, the leading cause of death is cardiovascular disease (CVD). Hypertension is the main risk factor for CVD; about 50% of the adult population suffers from this condition. High sodium (Na) intake combined with low potassium (K) intake can trigger cardiovascular disorders such as high blood pressure (BP). The aim of this study was to estimate the mean excretion of Na and K in Mexican adults using a spot urine sample, and its association with cardiovascular disorders. Information on 2,778 adults, 20-59 years of age, who participated in ENSANUT-2016 was analyzed. Na and K were estimated using Tanaka formulae. Biomarkers such as glucose, total cholesterol, triglycerides, HDL cholesterol and LDL cholesterol, and anthropometry were measured. Mean Na was 3,354 mg/day (95%CI: 3,278, 3,429), 1,440 mg/day of K (95%CI: 1,412, 1,469), and the Na-K ratio was 2.4. The excretion of Na was greater in adults with high BP (3,542 mg/day) compared to those with normal BP (3,296 mg/day). In adults with hypertension, excretion of K was 10% greater (1,534 mg/day) than in adults with normal BP (1,357 mg/day). In adults with moderate reduction of renal function, Na excretion was 22% less (2,772 mg/day) than in adults with normal kidney function (3,382 mg/day). The results of this study show that the cardiovascular health of Mexican adults is at risk, as they showed high Na excretion and low K excretion.
RESUMO
The study aimed to evaluate the antithrombotic action of Acrocomia aculeata pulp oil (AAPO) in natura, in an in vitro experimental model. AAPO was obtained by solvent extraction, and its chemical characterization was performed by gas chromatography coupled to a mass spectrometer (GC-MS). In vitro toxicity was evaluated with the Trypan Blue exclusion test and in vivo by the Galleria mellonella model. ADP/epinephrine-induced platelet aggregation after treatment with AAPO (50, 100, 200, 400, and 800 µg/mL) was evaluated by turbidimetry, and coagulation was determined by prothrombin activity time (PT) and activated partial thromboplastin time (aPTT). Platelet activation was measured by expression of P-selectin on the platelet surface by flow cytometry and intraplatelet content of reactive oxygen species (ROS) by fluorimetry. The results showed that AAPO has as major components such as oleic acid, palmitic acid, lauric acid, caprylic acid, and squalene. AAPO showed no toxicity in vitro or in vivo. Platelet aggregation decreased against agonists using treatment with different concentrations of AAPO. Oil did not interfere in PT and aPTT. Moreover, it expressively decreased ROS-induced platelet activation and P-selectin expression. Therefore, AAPO showed antiplatelet action since it decreased platelet activation verified by the decrease in P-selectin expression as well as in ROS production.

BACKGROUND: The COVID-19 pandemic has highlighted a correlation between cardiac complications and elevated cardiac biomarkers, which are linked to poorer clinical outcomes. OBJECTIVE: This study aims to determine the clinical impact of cardiac biomarkers in COVID-19 patients in Latin America. SUBJECTS AND METHODS: The CARDIO COVID 19-20 Registry is a multicenter observational study across 44 hospitals in Latin America and the Caribbean. It included hospitalized COVID-19 patients (n = 476) who underwent troponin, natriuretic peptide, and D-dimer tests. Patients were grouped based on the number of positive biomarkers. RESULTS: Among the 476 patients tested, 139 had one positive biomarker (Group C), 190 had two (Group B), 118 had three (Group A), and 29 had none (Group D). A directly proportional relationship was observed between the number of positive biomarkers and the incidence of decompensated heart failure. Similarly, there was a proportional relationship between the number of positive biomarkers and increased mortality. In Group B, patients with elevated troponin and natriuretic peptide and those with elevated troponin and D-dimer had 1.4 and 1.5 times higher mortality, respectively, than those with elevated natriuretic peptide and D-dimer. CONCLUSIONS: In Latin American COVID-19 patients, a higher number of positive cardiac biomarkers is associated with increased cardiovascular complications and mortality. These findings suggest that cardiac biomarkers should be utilized to guide acute-phase treatment strategies.
RESUMO
BACKGROUND AND AIMS: Understanding the amounts of intensity-specific movement needed to attenuate the association between sedentary time and mortality may help to inform personalized prescription and behavioral counselling. Herein, we examined the joint associations of sedentary time and intensity-specific physical activity with all-cause and cardiovascular disease (CVD) mortality. METHODS: Prospective cohort study including 73,729 adults from the UK Biobank who wore an Axivity AX3 accelerometer on their dominant wrist for at least 3 days, being one a weekend day, between June 2013 and December 2015. We considered the median tertile values of sedentary time and physical activity in each intensity band to determine the amount of physical activity needed to attenuate the association between sedentary time and mortality. RESULTS: During a median of 6.9 years of follow-up (628,807 person-years), we documented 1521 deaths, including 388 from CVD. Physical activity of any intensity attenuated the detrimental association of sedentary time with mortality. Overall, at least a median of 6 min/day of vigorous physical activity, 30 min/day of MVPA, 64 min/day of moderate physical activity, or 163 min/day of light physical activity (mutually-adjusted for other intensities) attenuated the association between sedentary time and mortality. High sedentary time was associated with higher risk of CVD mortality only among participants with low MVPA (HR 1.96; 95% CI 1.23 to 3.14). CONCLUSIONS: Different amounts of each physical activity intensity may attenuate the association between high sedentary time and mortality.

AIMS: To external validate the SCORE2, AHA/ACC Pooled Cohort Equation (PCE), Framingham Risk Score (FRS), Non-Laboratory INTERHEART Risk Score (NL-IHRS), Globorisk-LAC, and WHO prediction models and compare their discrimination and calibration capacity. METHODS: Validation in individuals aged 40-69 years with at least 10 years follow-up and without baseline use of statins or cardiovascular diseases from the Prospective Urban Rural Epidemiology prospective cohort study (PURE)-Colombia. For discrimination, the C-statistic, and Receiver Operating Characteristic curves with the integrated area under the curve (AUCi) were used and compared. For calibration, the smoothed time-to-event method was used, choosing a recalibration factor based on the integrated calibration index (ICI). In the NL-IHRS, linear regressions were used. RESULTS: In 3,802 participants (59.1% women), baseline risk ranged from 4.8% (SCORE2 women) to 55.7% (NL-IHRS). After a mean follow-up of 13.2 years, 234 events were reported (4.8 cases per 1000 person-years). The C-statistic ranged between 0.637 (0.601-0.672) in NL-IHRS and 0.767 (0.657-0.877) in AHA/ACC PCE. Discrimination was similar between AUCi. In women, higher overprediction was observed in the Globorisk-LAC (61%) and WHO (59%). In men, higher overprediction was observed in FRS (72%) and AHA/ACC PCE (71%). Overestimations were corrected after multiplying by a factor derived from the ICI. CONCLUSIONS: Six prediction models had a similar discrimination capacity, supporting their use after multiplying by a correction factor. If blood tests are unavailable, NL-IHRS is a reasonable option. Our results suggest that these models could be used in other countries of Latin America after correcting the overestimations with a multiplying factor.
Detecting people at high risk of cardiovascular disease and implementing preventive interventions in this population is a key strategy in primary prevention. Recently, new risk calculation tools have been developed, but before their application and routine use in populations different from those where it was developed, it's necessary to validate them. The recommendations for predicting cardiovascular risk in Colombia's guidelines are based on studies with noteworthy limitations. This study involving 3,802 healthy individuals in Colombia supports the recommendation of using these prediction models. The estimation result should be multiplied by a correction factor, because most of the prediction models overestimate cardiovascular risk. For example, the correction factors suggested in women for AHA/ACC PCE and SCORE2 are 0.54 and 0.75, respectively. In men, the correction factors suggested in AHA/ACC PCE and SCORE2 are 0.28 and 0.61, respectively. Therefore, the present study with a contemporary population provides additional evidence to update these recommendations in Colombia and perhaps in Latin America.
