RESUMO

ABSTRACT Purpose: This study investigated the relationship between blood pressure and intraocular pressure in treatmentnaive, non-glaucoma patients with different blood pressure statuses, focusing on the 24-h ocular volume and nocturnal blood pressure decline. Methods: Treatment-naive, non-glaucoma patients undergoing hypertension evaluation were enrolled as study participants. Simultaneous 24-h ambulatory blood pressure measurement and 24-h ocular volume recording with a contact lens sensor. We also compared ocular volume curve parameters between normotensive and hypertensive patients, as well as between those with and without nocturnal blood pressure decline. Results: A total of 21 patients, including 7 normotensive and 14 treatment-naive hypertensive individuals, were included in the study. of them, 11 were dippers and 10 were non-dippers. No significant difference in the 24-h ocular volume slope was observed between the hypertensive and normotensive patients (p=0.284). However, dippers had a significantly higher 24-h ocular volume slope (p=0.004) and nocturnal contact lens sensor output (p=0.041) than non-dippers. Conclusion: Nocturnal blood pressure decline, rather than the blood pressure level, is associated with the increased 24-h ocular volume slope and nocturnal ocular volume. Further studies are required to determine whether the acceleration of glaucoma progression in dippers is primarily due to low blood pressure, high intraocular pressure, or a combination of both.

RESUMO

Abstract Introduction: Blood pressure (BP) assessment affects the management of arterial hypertension (AH) in chronic kidney disease (CKD). CKD patients have specific patterns of BP behavior during ambulatory blood pressure monitoring (ABPM). Objectives: The aim of the current study was to evaluate the associations between progressive stages of CKD and changes in ABPM. Methodology: This is a cross-sectional study with 851 patients treated in outpatient clinics of a university hospital who underwent ABPM examination from January 2004 to February 2012 in order to assess the presence and control of AH. The outcomes considered were the ABPM parameters. The variable of interest was CKD staging. Confounding factors included age, sex, body mass index, smoking, cause of CKD, and use of antihypertensive drugs. Results: Systolic BP (SBP) was associated with CKD stages 3b and 5, irrespective of confounding variables. Pulse pressure was only associated with stage 5. The SBP coefficient of variation was progressively associated with stages 3a, 4 and 5, while the diastolic blood pressure (DBP) coefficient of variation showed no association. SBP reduction was associated with stages 2, 4 and 5, and the decline in DBP with stages 4 and 5. Other ABPM parameters showed no association with CKD stages after adjustments. Conclusion: Advanced stages of CKD were associated with lower nocturnal dipping and greater variability in blood pressure.

Resumo Introdução: A avaliação da pressão arterial (PA) tem impacto no manejo da hipertensão arterial (HA) na doença renal crônica (DRC). O portador de DRC apresenta padrão específico de comportamento da PA ao longo da monitorização ambulatorial da pressão arterial (MAPA). Objetivos: O objetivo do corrente estudo é avaliar as associações entre os estágios progressivos da DRC e alterações da MAPA. Metodologia: Trata-se de um estudo transversal com 851 pacientes atendidos nos ambulatórios de um hospital universitário que foram submetidos ao exame de MAPA no período de janeiro de 2004 a fevereiro de 2012 para avaliar a presença e o controle da HA. Os desfechos considerados foram os parâmetros de MAPA. A variável de interesse foi o estadiamento da DRC. Foram considerados como fatores de confusão idade, sexo, índice de massa corporal, tabagismo, causa da DRC e uso de anti-hipertensivos. Resultados: A PA sistólica (PAS) se associou aos estágios 3b e 5 da DRC, independentemente das variáveis de confusão. Pressão de pulso se associou apenas ao estágio 5. O coeficiente de variação da PAS se associou progressivamente aos estágios 3a, 4 e 5, enquanto o coeficiente de variação da pressão arterial diastólica (PAD) não demonstrou associação. O descenso da PAS obteve associação com estágios 2, 4 e 5, e o descenso da PAD, com os 4 e 5. Demais parâmetros da MAPA não obtiveram associação com os estágios da DRC após os ajustes. Conclusão: Estágios mais avançados da DRC associaram-se a menor descenso noturno e a maior variabilidade da pressão arterial.

RESUMO

Pregnancy Hypertensive Disorders (PHD), particularly Preeclampsia (PE), are significant contributors to maternal-fetal morbidity and mortality, with chronic arterial hypertension (CH) being a major risk factor. The prevalence of CH has risen alongside obesity and advanced maternal age. While antihypertensive treatment mitigates adverse pregnancy outcomes, the duration of effective blood pressure (BP) control, termed Time in Therapeutic Range (TTR), has not been extensively studied in pregnant women. TTR, reflecting the proportion of time BP remains within target ranges, predicts long-term cardiovascular and renal events in the general population but remains unexplored in pregnancy. This study investigates the association between TTR, assessed through office BP (OBP) and ambulatory BP monitoring (ABPM), and PE development in pregnant women with CH. In a retrospective longitudinal study, data from 166 pregnant women with HA referred to our hospital analyzed. BP was measured using OBP and ABPM from 10 weeks of gestation, with TTR calculated as the percentage of visits where BP remained within target ranges. The study defined four TTR control groups: 0%, 33%, 50-66%, and 100%. Results showed that 28% of the participants developed PE, with a higher incidence correlating with lower TTR in ABPM. TTR in ABPM was a significant predictor of PE risk, with the best-controlled group (100% TTR) demonstrating a 92% reduced risk compared to those with 0% TTR. The agreement between OBP and ABPM TTR was low, emphasizing the importance of ABPM for accurate BP monitoring in pregnancy. This study indicates that integrating ABPM for TTR assessment in high-risk pregnancies has the potential to reduce maternal and fetal complications.

RESUMO

BACKGROUND: The elevated blood pressure (BP) and lower cardiac autonomic modulation (CAM) are associated with higher morbidity mortality risk among older adults. Although exercise is an important intervention for cardiovascular promotion, it is unclear whether combat sports training could benefit cardiovascular outcomes as much as autonomic in this population. This study compared the effects of 12 weeks of Muay Thai (MT) training against functional training (FT) on CAM and hemodynamic parameters in older adults. METHODS: The sample consisted of 50 older adults (41 women; 66.0 ± 5.3 years old), who were equaly randomized into FT (n = 25) and MT (n = 25) intervention groups. CAM was measured by 30-min rest heart rate variability. Systolic blood pressure (SBP), diastolic blood pressure (DBP) and resting heart rate (RHR) were measured using an automatic oscillometric device. Pulse pressure (PP) and the double product (DP) were also calculated. The interventions were carried out three times a week, with 60-min length per session, during 12 consecutive weeks. The intensity of the interventions was measured using the subjective perception of exertion scale and by accelerometer. Two-factor repeated measures analysis of covariance was used for groups comparison, considering intervention group and body mass as factors. The 95% confidence interval of the difference (95%CIdif) was also calculated and the effect size was measured using partial eta squared (η2p). RESULTS: CAM indices did not show significant changes across moments and intervention groups. In hemodynamic parameters, only in DBP was there an effect of the moment (F1,39 = 8.206; P = 0.007; η2p = 0.174, large) and interaction effect between group*moment (F1,39 = 7.950; P = 0.008; η2p = 0.169, large). Specifically, the MT group at the post-training moment showed lower DBP (P = 0.010; 95%CIdif = -13.3; -1.89) in relation to the FT group. Furthermore, the MT group showed a decrease in DBP during training (P = 0.002; 95%CIdif = -10.3; -2.6). Also, an increase in training intensity was also found over the 12 weeks in FT, with no difference between the groups. CONCLUSION: After 12 weeks of MT practice there was a reduction in DBP compared to FT in older adults. TRIAL REGISTRATION: NCT03919968 Registration date: 01/02/2019.

RESUMO

INTRODUCTION: Type 2 diabetes is a major public health issue in Mexico due to its high prevalence and its projection for the coming years for this disease. Findings on multidisciplinary care related to chronic diseases have proven effective, based on measurement of patient-centered outcomes, The Center of Comprehensive Care for Patients with Diabetes (CAIPaDi) is a multidisciplinary program focused on reducing diabetes complications. This case study aims to illustrate the results of implementing health outcomes measurements and demonstrate the beneficial effects of establishing a comprehensive model of care through a patient-centered approach. METHODS: A descriptive analysis of the comprehensive care indicators of patients with type 2 diabetes treated in the CAIPaDi program between 2013 and 2023 was conducted. The results were structured according to the standard set of outcomes for diabetes proposed by the International Consortium for Health Outcomes Measurements (ICHOM). RESULTS: The baseline and prospective registration of consultations was completed for five years, complying with 25 of the 26 indicators of the ICHOM set. In diabetes control, 56.5% of patients had A1c ≤ 7%, 87.9% had BP ≤ 130/80 mmHg, 60.9% had LDL-cholesterol < 100 mg/dl, and obesity rates decreased from 42.19% to 30.6% during annual consultations. Fewer years of diagnosis before the first visit is key to overall improvement in program adherence (P = 0.02). In acute events, a hyperglycemic crisis occurred in only two cases and severe hypoglycemia episodes in 8 patients. For chronic complications, no lower limb amputations occurred. Cardiovascular outcomes occurred in < 1%. Periodontal disease was analyzed, and periodontitis decreased from 82.9% to 78.7%. Mortality reports were low, with COVID-19 being the main cause of death. Patient-reported outcomes demonstrated reductions in anxiety, depression, and diabetes distress during follow-up. CONCLUSION: Registering quality-of-care indicators is feasible in a comprehensive care program. It allows improving the medical, mental health, and lifestyle outcomes of patients with type 2 diabetes and provides relevant data for planning health programs. A quick diagnosis before program adherence is crucial for overall improvement in patients.

RESUMO

The aim of this study was to highlight the importance of measuring blood pressure (BP) to identify new, known, and treated individuals with hypertension and to raise awareness in the general population about the importance of good BP control. In Paraguay, 3663 individuals aged ≥18 years of both sexes were recruited from May to November 2021 as part of the May Measurement Month (MMM) campaign, which was initiated by the International Society of Hypertension in 2017. Volunteers of 18 regional health teams applied the questionnaire provided by the MMM 2021 organization throughout the country. Due to COVID-19 constraints, the majority of the questionnaires (52.2%) were administered in health centres of the Ministry of Health and concluded with three BP and pulse readings using OMRON-automated BP measurement devices. Hypertension was defined as a systolic BP ≥ 140 mmHg or as a diastolic BP ≥ 90 mmHg or taking antihypertensive medication. We found that 57.4% of screenees were hypertensive and 72.9% of these (82.3% of women and 59.4% of men) had known hypertension. Of patients with hypertension, 70.1% were on antihypertensive medication, and 40.9% had controlled BP (<140/90 mmHg). Among hypertensives detected, 79.7% of women were on antihypertensive medication and 44.1% had controlled BP, while 56.4% of men were on treatment and 34.3% had controlled BP. In summary, we found high levels of hypertension with high rates of awareness and treatment particularly among women, although control rates were low particularly among men. This may be because most screening was conducted predominately in hospital settings.

RESUMO

Arterial hypertension is a growing burden worldwide, leading to over 10.8 million deaths each year. Before the outbreak of the COVID-19 pandemic, cardiovascular diseases were the main cause of death in Ecuador. Hypertension is the main risk factor for the major cause of death, coronary and cerebrovascular disease. The 2021 May Measurement Month Campaign (MMM21) is a global initiative by the International Society of Hypertension aimed at raising awareness of high blood pressure (BP) and to provide a temporary solution for opportunistic screening until more systematic approaches can be established. A cross-sectional survey was carried out in May 2021 across 22 health centres in Ecuador. The average age of participants was 44.7 ± 15.8 years. Blood pressure measurement, the definition of hypertension (mean of the 2nd and 3rd BP measurements ≥ 140/90 mmHg or on medication for high BP), and statistical analysis followed the standard MMM protocol. In total, 1326 volunteers participated in MMM21. After multiple imputation of missing BP readings, 423 (31.9%) had hypertension. Of those, 70.5% were receiving antihypertensive medication. Of individuals receiving antihypertensive medication, 50.0% had uncontrolled BP. Overall, of 423 participants with hypertension, only 35.2% had their BP controlled (<140/90 mmHg). MMM21 demonstrated a high prevalence of hypertension in Ecuador during the COVID-19 pandemic. It was the largest BP screening campaign done in Ecuador thus far. The high percentage of persons untreated or with uncontrolled hypertension while on pharmacologic treatment suggests that appropriate screening can help to identify a significant number of people with elevated BP and those inadequately treated. These data should attract the attention of doctors and health care providers in Ecuador.

RESUMO

Hypertension continues to be the leading cause of death and disability in the industrialized world, with a high level of unawareness and unacceptably poor control rates. Therefore, the Argentinian Society of Hypertension, in association with the May Measurement Month (MMM) charity, implemented an awareness campaign during May 2021. A voluntary cross-sectional survey was carried out during the month of May 2021 in public spaces and health centres across 29 cities in Argentina. Hypertension was defined as systolic blood pressure (BP) ≥ 140 mmHg and/or diastolic BP ≥ 90 mmHg based on the mean of the second and third of three BP measurements or in those volunteers on treatment for high BP. Statistical analysis including multiple imputation followed the MMM protocol. A total of 26 070 individuals (average age 53.4 years, 14 816 women and 11 254 men) were evaluated. The age- and sex-standardized mean BP was 125.1/77.6 mmHg. Of all participants, 54.4% had hypertension. Although 79.8% of the hypertensive participants were aware of their condition and 76.9% were on antihypertensive treatment, only 42.5% of all individuals with hypertension had their BP controlled (<140/90 mmHg). Of those on antihypertensive medication, 55.3% were controlled. The low level of hypertension control highlights the critical need for community-based prevention strategies to increase the awareness and control of hypertension, thereby reducing the enormous health burden attributed to this condition.

RESUMO

Systematic reviews support the benefits of inspiratory muscle training (IMT) for exercise performance. Recently, many health benefits from IMT have been reported in older adults. Therefore, this work reviewed the literature focusing on IMT effects beyond physical performance in older adults, such as cardiorespiratory, metabolic, and postural balance outcomes. Searches were conducted with the following terms: ("respiratory muscle training" OR "inspiratory muscle training") OR ("inspiratory muscle strength training") AND ("elderly" OR "older" OR "aging" OR "aging"), and using the databases: MEDLINE (PubMed), SCOPUS and EUROPE PMC. Of the 356 articles found, 13 matched the inclusion criteria after screening. Based on reviewed studies, four to eight weeks of IMT (Mostly from 50 % up to 75 % of MIP, 7 days/week) improve cardiac autonomic control at rest and post-exercise, cerebrovascular response to orthostatic stress, static and dynamic balance, blood pressure control, endothelial function, and oxidative stress in older adults. The benefits of IMT in cardiac autonomic and vascular functions are reversed after training cessation. It thus appears that IMT promotes broad physiological gains for the older population. It is necessary to carry out more randomized clinical trials on the subject to confirm the findings of this research.

RESUMO

Background: Arterial hypertension is highly prevalent in Mexico; nevertheless, there are limited insights regarding its management during the COVID-19 pandemic. Here, we estimate the prevalence of clinical and treatment profiles of arterial hypertension and explore associated factors for undiagnosed and uncontrolled hypertension using a cross-sectional survey endorsed by the Collaborative Group on Arterial Hypertension from the Mexican Institute of Social Security. Methods: Our survey was conducted from May to November 2021 using the May-Measurement Month 2021 protocols of the International Society of Hypertension. Arterial hypertension (defined as: blood pressure [BP] ≥140/90 mmHg, previous diagnosis, or taking antihypertensives) and its clinical and treatment profiles were classified according to the World Hypertension League Expert Committee. Mixed-effects logistic regression models were used to explore associated factors for undiagnosed and uncontrolled hypertension. Results: Among 77,145 screened participants (women: 62.4%; median age: 46 [IQR: 32-59] years), the prevalence of arterial hypertension was 35.7% (95% CI: 35.3-36.0, n = 27,540). Among participants with arterial hypertension, 30.9% (95% CI: 30.4-31.5, n = 8,533) were undiagnosed, 6.6% (95% CI: 6.3%-6.9%, n = 1,806) were diagnosed but untreated, 43.4% (95% CI: 42.9-44.0, n = 11,965) had uncontrolled hypertension, and only 19% (95% CI: 18.6%-19.5%, n = 5,236) achieved hypertension control (BP < 130/80 mmHg). Explored associated factors for undiagnosed and uncontrolled hypertension include being men, living in the central and southern regions, lower educational attainments, higher use of pharmacological agents, and previous COVID-19 infection. Conclusion: Our findings suggest that adverse arterial hypertension profiles, mainly undiagnosed and uncontrolled hypertension, were highly prevalent during the context of the COVID-19 pandemic in Mexico.

RESUMO

BACKGROUND: We conducted a systematic review and meta-analysis to examine the effect of dietary intake of cocoa on anthropometric measurements, lipid and glycemic profiles, and blood pressure levels in adults, with and without comorbidities. METHODS: The databases used were MEDLINE (PubMed), EMBASE, Web of Science, Cochrane, LILACS, and SciELO. The eligible studies were randomized clinical trials (RCTs) involving adults undergoing cocoa consumption (cocoa extract or ≥70% cocoa dark chocolate) for ≥4 weeks that evaluated at least one of the following markers: body weight, body mass index (BMI), waist/abdominal circumference, total cholesterol, LDL-c, triglycerides, HDL-c, blood glucose, glycated hemoglobin (HbA1c), and systolic and diastolic blood pressure (SBP/DBP). RESULTS: Thirty-one studies were included, totaling 1986 participants. Cocoa consumption showed no effects on body weight, BMI, waist circumference, triglycerides, HDL-c and HbA1c. Yet, there was a reduction in total cholesterol (-8.35 mg/dL, 95% CI -14.01; -2.69 mg/dL), LDL-c (-9.47 mg/dL, 95% CI -13.75; -5.20 mg/dL), fasting blood glucose (-4.91 mg/dL, 95% CI -8.29; -1.52 mg/dL), SBP (-2.52 mmHg, 95% CI -4.17; -0.88 mmHg), and DBP (-1.58 mmHg, 95% CI -2.54; -0.62 mmHg). CONCLUSIONS: The consumption of cocoa showed protective effects on major cardiometabolic risk markers that have a clinical impact in terms of cardiovascular risk reduction.

RESUMO

BACKGROUND: Left ventricular diastolic dysfunction indicated by elevated pulmonary capillary wedge pressure (ePCWP) may worsen cardiorespiratory status in bronchopulmonary dysplasia (BPD), but the scope of ePCWP by cardiac catheterization is not well described. METHODS: This single-center retrospective cohort study included infants with BPD without congenital heart disease, significant intracardiac shunts, or pulmonary vein stenosis who underwent cardiac catheterization from 2010 to 2021. ePCWP was defined as >10 mmHg. Quantitative measures of ventricular systolic and diastolic function were performed on existing echocardiograms. Patients with and without ePCWP were compared using the Chi-squared or Wilcoxon rank-sum tests. Associations between catheterization hemodynamics and echocardiographic parameters were assessed by simple linear regression. RESULTS: Seventy-one infants (93% Grade 2 or 3 BPD) met inclusion criteria, and 30 (42%) had ePCWP. Patients with ePCWP were older at catheterization (6.7 vs. 4.5 months, p < 0.001), more commonly underwent tracheostomy (66.7% vs. 29.3%, p = 0.003), and had higher mean systemic blood pressure [64.5 (56.0, 75.0) vs. 47.0 (43.0, 55.0) mm Hg, p < 0.001], higher systemic vascular resistance [11.9 (10.4, 15.6) vs. 8.7 (6.7, 11.2) WU*m2, p < 0.001), and lower cardiac index [3.9 (3.8, 4.9) vs. 4.7 (4.0, 6.3) L/min/m2, p = 0.03] at catheterization. Mean pulmonary artery pressure, pulmonary vascular resistance, and mortality were similar between the groups. Echocardiographic indices of left ventricular diastolic dysfunction did not correlate with PCWP. CONCLUSIONS: ePCWP was common in infants with severe BPD who underwent cardiac catheterization in this cohort. The association between ePCWP and higher systemic blood pressure supports further study of afterload reduction in this population.

RESUMO

BACKGROUND: Self-measurement of blood pressure (SMBP) is endorsed by current guidelines for diagnosing and managing hypertension (HTN). We surveyed individuals in a rural healthcare system on practices and attitudes related to SMBP that could guide future practice. METHODS: Survey questions were sent via an online patient portal to a random sample of 56,275 patients with either BP > 140/90 mm Hg or cardiovascular care in the system. Questions addressed home blood pressure (BP) monitor ownership, use, willingness to purchase, desire to share data with providers, perceptions of patient education, and patient-centeredness of care. Multivariable logistic regression was used to examine patient characteristics associated with SMBP behaviors. RESULTS: The overall response rate was 12%, and 8.4% completed all questions. Most respondents, 60.9%, owned a BP monitor, while 51.5% reported checking their BP at home the month prior. Among device owners, 45.1% reported receiving instructions on SMBP technique, frequency, and reading interpretation. Only 29.2% reported sharing readings with providers in the last 6 months, whereas 57.9% said they would be willing to do so regularly. Older age, female sex, and higher income were associated with a higher likelihood of device ownership. Younger age, lower income, and Medicaid insurance were associated with a greater willingness to share SMBP results with providers regularly. CONCLUSIONS: While a significant proportion of respondents performed SMBP regularly, many reported insufficient education on SMBP, and few shared their home BP readings with providers. Patient-centered interventions and telemedicine-based care are opportunities that emerged in our survey that could enhance future HTN care.

RESUMO

PURPOSE: We tested the hypothesis that heat stress influences the closed-loop cardio-postural control by an increased blood pressure (BP) drop and postural sway. METHODS: Fourteen healthy individuals (eight women) performed two orthostatic tests under thermal reference (TC; ~ 24 ºC) and HOT (~ 38 ºC) conditions. The center-of-pressure (COP) displacements and the electromyography (EMG) activity of the calf muscles (medial gastrocnemius and tibialis anterior) were recorded during the initial orthostasis (ORT onset) after the supine-to-stand challenge. At the same period, BP (beat-to-beat) was continuously monitored, and supine-to-stand variations (∆%) were calculated. Sublingual temperature (Tsl) was measured as a surrogate of internal temperature. RESULTS: Tsl increased in HOT compared to TC (TC 36.5 ± 0.3 vs. HOT 36.7 ± 0.3 ºC; p < 0.01). COP distance was greater in HOT compared to TC condition (TC 596.6 ± 242.4 vs. HOT 680.2 ± 249.1 mm; p < 0.01). EMG activity of the gastrocnemius decreased in HOT compared to TC condition (TC 95.5 ± 19.8 vs. HOT 78.4 ± 22.8%mV; p = 0.02). EMG of tibialis did not change between TC and HOT (TC 83.5 ± 42.9 vs. HOT 66.1 ± 31.9% mV; p = 0.29). BP showed a greater fall in HOT compared to TC condition (∆%TC - 24.5 ± 13.2 vs. ∆%HOT - 33.2 ± 20.2%; p = 0.01). CONCLUSION: Heat stress causes a greater fall in blood pressure and a reduction in musculoskeletal pump activity during orthostatic onset. These effects could be potential mechanisms that underlie augmented postural instability under a heated environment.

RESUMO

The byproduct of Salvia hispanica (chia) seed oil extraction by cold pressing, also known as expeller, possesses a high nutritional value. It is rich in proteins, fibers, minerals, and has a residual oil content of 7-11%, which is rich in omega 3 linolenic acid (ALA). However, this byproduct has been historically undervalued. Thus, the aim of current work was to study the effects of consuming of a rich in chia expeller diet on a rabbit model of metabolically unhealthy normal weight to validate their use as a functional food. Rabbits were fed different diets for a period of 6 weeks: a standard diet (CD), a high-fat diet (HFD), a rich in expeller CD (Exp-CD) and a rich in expeller HFD (Exp-HFD). The Exp-HFD attenuated the rise in basal glucose, TyG index, triglycerides, cholesterol and non-HDL cholesterol induced by the HFD. Both rich in expeller diets reduced mean arterial blood pressure (MAP) and increase liver and fat ALA levels compared to their respective controls. Furthermore, the angiotensin converting enzyme (ACE) activity was lower in the lungs of animals fed on rich in expeller diets compared to their respective controls. In vitro studies showed that ALA inhibited ACE activity. The evaluation of vascular reactivity revealed that rich in expeller diets improved angiotensin II affinity and reduced contractile response to noradrenaline. In conclusion, the consumption of rich in expeller diets showed beneficial effects in preventing cardiovascular risk factors such as insulin resistance, dyslipidemia and MAP. Therefore, its use as functional ingredient holds significant promise.

RESUMO

INTRODUCTION: A new cardiovascular risk (CVR) calculator that incorporates Lipoprotein(a) [Lp(a)] levels has recently been designed. AIMS: To estimate CVR using the new score and to identify the reduction in low-density lipoprotein cholesterol (LDL-C) or systolic blood pressure (SBP) necessary to balance the risk attributable to Lp(a). METHODS: CVR throughout life and at 10 years was estimated with the new score in patients in primary prevention, both considering and not considering the value of Lp(a). When the estimated risk considering Lp(a) levels exceeded the baseline risk, the reduction in LDL-C levels or SBP necessary to balance the risk attributable to Lp(a) was calculated. RESULTS: In total, 671 patients (mean age 54.2 years, 47.2% women) were included. Globally, 22.7% of the population had high Lp(a) values (> 50 mg/dL or > 125 nmol/L). When calculating CVR throughout life and considering the Lp(a) value, the global risk increased in 66.7% of cases (median 19.3%). Similar results were observed when we assessed the 10-year risk. The risk associated with Lp(a) could be completely compensated by decreasing LDL-C (average 21 mg/dL) or SBP (average 6.3 mmHg) in 79.2% and 74.7% of cases, respectively. CONCLUSION: When calculating the CVR with the new score, two-thirds and one-third of the population were bidirectionally recategorized as 'up' or 'down,' respectively. The decrease in LDL-C or SBP mitigated the increased risk caused by Lp(a) levels across a substantial proportion of patients.

RESUMO

CONTEXT: Nut-enriched diets have a positive impact on cardiovascular risk factors, such as body mass, blood pressure, and fasting blood glucose. However, studies in individuals undergoing secondary cardiovascular prevention show controversial results. OBJECTIVE: This systematic review with meta-analysis assessed the effect of nut supplementation on anthropometric, glycemic, and blood pressure indices in patients with atherosclerotic cardiovascular disease, as well as the frequency of adverse events. DATA SOURCES: Six databases were used for the search-PubMed, Cochrane Library, EMBASE, BVS (Biblioteca Virtual da Saude), Web of Science, and ClinicalTrials.gov-until February 2023, with no language restrictions. DATA EXTRACTION: The Cochrane Handbook for Systematic Reviews of Interventions methodology and the PICOS (Population, Intervention, Comparison, Outcome, Setting/design) strategy were used. Seven independent reviewers were involved in data extraction and resolution of disagreements. Certainty of the evidence was evaluated using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) system. DATA ANALYSIS: From 5187 records identified, 6 publications containing data referring to 5 randomized clinical trials (n = 436) were included in the final analyses. The nuts evaluated were almonds, pecans, Brazil nuts, and mixed nuts, with portions that varied between 5 g and 85 g (median: 30 g/day). The intervention period varied between 6 and 12 weeks. The nuts had no effect on fasting glucose and anthropometric indices, although the certainty of the evidence for most of these outcomes was low or very low. They also had no effect on systolic (mean difference [MD]: -1.16 mmHg [95% CI, -5.68 to 3.35], I2 = 0%-moderate certainty of evidence) or diastolic (MD: 0.10 mmHg [95% CI, -2.30 to 2.51], I2 = 0%-high certainty of evidence) blood pressure. It was not possible to aggregate data on adverse events. CONCLUSION: Nut supplementation had no effect on blood pressure, fasting glucose, or anthropometric profile in the context of atherosclerotic cardiovascular disease.
