RESUMEN

BACKGROUND: Concomitant coronavirus 2019 (COVID-19) infection and ST-segment elevation myocardial infarction (STEMI) are associated with increased adverse in-hospital outcomes. OBJECTIVES: This study aimded to evaluate the angiographic, procedural, laboratory, and prognostic differences in COVID-19-positive and negative patients with STEMI undergoing primary percutaneous coronary intervention (PCI). METHODS: A single-center, retrospective, observational study was conducted between November 2020 and August 2022 in a tertiary-level hospital. According to their status, patients were divided into two groups (COVID-19 positive and negative). All patients were admitted due to confirmed STEMI and treated with primary PCI. In-hospital and angiographic outcomes were compared between the two groups. Two-sided p-values < 0.05 were accepted as statistically significant. RESULTS: Of the 494 STEMI patients enrolled in this study, 42 were identified as having a positive dagnosis for COVID-19 (8.5%), while 452 were negative. The patients who tested positive for COVID-19 had a longer total ischemic time than did those who tested negative for COVID-19 (p=0.006). Moreover, these patients presented an increase in stent thrombosis (7.1% vs. 1.7%, p=0.002), length of hospitalization (4 days vs. 3 days, p= 0.018), cardiogenic shock (14.2% vs. 5.5 %, p= 0.023), and in-hospital total and cardiac mortality (p<0.001 and p=0.032, respectively). CONCLUSIONS: Patients with STEMI with concomitant COVID-19 infections were associated with increased major adverse cardiac events. Further studies are needed to understand the exact mechanisms of adverse outcomes in these patients.

FUNDAMENTO: A infecção concomitante por coronavírus 2019 (COVID-19) e o infarto do miocárdio com supradesnivelamento do segmento ST (IAMCSST) estão associados ao aumento de desfechos adversos hospitalares. OBJETIVOS: O estudo teve como objetivo avaliar as diferenças angiográficas, de procedimentos, laboratoriais e prognósticas em pacientes positivos e negativos para COVID-19 com IAMCSST submetidos à intervenção coronária percutânea primária (ICP). MÉTODOS: Realizamos um estudo observacional retrospectivo e unicêntrico entre novembro de 2020 e agosto de 2022 em um hospital de nível terciário. De acordo com o seu estado, os pacientes foram divididos em dois grupos (positivo ou negativo para COVID-19). Todos os pacientes foram internados por IAMCSST confirmado e foram tratados com ICP primária. Os desfechos hospitalares e angiográficos foram comparados entre os dois grupos. P-valores bilaterais <0,05 foram aceitos como estatisticamente significativos. RESULTADOS: Dos 494 pacientes com IAMCSST inscritos nesse estudo, 42 foram identificados como positivos para COVID-19 (8,5%) e 452, como negativos. Os pacientes que testaram positivos para COVID-19 tiveram um tempo isquêmico total maior do que os pacientes que testaram negativos para COVID-19 (p = 0,006). Além disso, esses pacientes apresetaram um aumento na trombose de stent (7,1% vs. 1,7%, p = 0,002), no tempo de internação (4 dias vs. 3 dias, p = 0,018), no choque cardiogênico (14,2% vs. 5,5%, p = 0,023) e na mortalidade hospitalar total e cardíaca (p <0,001 e p = 0,032, respectivamente). CONCLUSÕES: Pacientes com IAMCSST com infecções concomitantes por COVID-19 foram associados ao aumento de eventos cardíacos adversos maiores. Mais estudos são necessários para compreender os mecanismos exatos dos desfechos adversos nesses pacientes.

RESUMEN

BACKGROUND: Silent cerebral infarction (SCI) is a neuronal injury without a clinically apparent stroke or transient ischaemic attack. Left atrial cardiomyopathy is closely associated with SCI. P wave changes in the electrocardiogram (ECG) provide significant information about the development of atrial cardiomyopathy. This study evaluated the role of P wave parameters and indices and a novel ECG parameter in predicting SCI, future cerebrovascular events, and atrial fibrillation/flutter. MATERIALS AND METHODS: A total of 272 patients were retrospectively screened and divided into two groups according to SCI. Cerebrovascular events and atrial fibrillation/flutter were defined as the study's outcomes. P wave parameters, indices, and a novel ECG parameter called the P wave ratio (PWR) were calculated from ECGs, and the relationship between SCI and outcomes was investigated. RESULTS: The maximum P wave duration (PWD), P wave dispersion (PWdisp), PWD measured from the D2 lead (PWDD2), P wave peak time measured from the D2 lead (PWPTD2), PWPT measured from the V1 lead (PWPTV1), and P wave terminal force (PWTFV1) were significantly longer in the SCI group. Both partial and advanced inter atrial block (IAB) were significantly high in the SCI group. The novel parameter P wave ratio (PWR) was significantly longer in the SCI group (0.55 ± 0.08 vs. 0.46 ± 0.09; p < 0.001). In multivariate regression analysis, PWdisp (OR: 1.101, p < 0.001), PWPTD2 (OR: 1.095, p = 0.017), and PWR (OR: 1.231, p < 0.001) were found to be independent predictors of SCI. Cox regression analysis revealed that the PWR (HR 1.077; 95% CI 1.029-1.128; p = 0.001) was associated with cerebrovascular events and atrial fibrillation/flutter. CONCLUSION: In our study, we observed that PWR could be a valuable parameter for predicting SCI and future cerebrovascular events.

RESUMEN

Sodium-glucose cotransporter-2 (SGLT-2) inhibitors are the latest approved class of oral antidiabetic agents that inhibit renal SGLT-2 receptors and increase urinary glucose excretion in the luminal membrane of the proximal tubule. Diabetic ketoacidosis (DKA) is a triad of hyperglycemia, ketosis, and a high anion gap with metabolic acidosis. We present the case of 61 years-old men with severe euglycemic DKA (EDKA) complicated ST-segment elevation myocardial infarction following SGLT-2 inhibitor therapy for type 2 diabetes mellitus. Atypical presentation of ketoacidosis without hyperglycemia can delay diagnosis and may result in catastrophic complications. Quick diagnosis, appropriate clinical and biochemical assessment, and effective treatment protocols ensure successful resolution of EDKA.

RESUMEN

BACKGROUND/OBJECTIVE: The endovascular approach is the first choice of treatment in high-risk patients suffering from Leriche syndrome. Although many techniques and devices have been developed, there are still difficulties in accessing the true lumen. Herein, we reported a novel technique to increase the support and ease of crossing the lesion. METHOD: We presented a case report of a 45-year-old male patient with Leriche syndrome. The patient refused surgery; therefore, he was scheduled for endovascular treatment. RESULTS: We attempted to cross the right and left common iliac occlusions by intraluminal crossing. The left common iliac artery couldn't be cannulated despite the stiff wires and percutaneous intentional extraluminal revascularization (PIER). Afterward, a cross-over approach was performed from the right side to reach the ostium of the left common iliac artery. To increase the support, a non-absorbable suture was stitched up to the tip of the guiding catheter and kept slightly taut like a lasso. Finally, successful penetration was achieved with the novel assistive technique. CONCLUSION: Endovascular treatment for Leriche syndrome is a precious alternative to open surgery. Intraluminal crossing, PIER, and re-entry devices are the most preferred techniques. Increasing the technical success of intraluminal crossing and PIER leads to an apparent reduction in cost.

RESUMEN

The purpose of this investigation was to investigate whether there was an association between the Naples prognostic score and the development of acute kidney injury (AKI) in ST-elevation myocardial infarction (STEMI) patients following primary percutaneous coronary intervention (pPCI). The study comprised 2901 consecutive STEMI patients who had pPCI. For each patient, the Naples prognostic score was determined. To evaluate the predictive performance of the Naples score (which included either continuous and categorical variables), we developed a Nested model and a nested model combined with the Naples score. The Naples prognostic score was the most significant predictor of AKI occurrence after admission creatinine, age, and contrast volume. The continuous Naples prognostic score model provided the best prediction performance and discriminative ability. The C-index of the Nested and full models with continuous Naples prognostic score were significantly higher than that of the Nested model. The decision curve analysis found that the overall model had a higher full range of probability of clinical net benefit than the baseline model, with a 10% AKI likelihood. The present study found that the Naples prognostic score may be useful to predict the risk of AKI in STEMI patients undergoing pPCI.

RESUMEN

OBJECTIVE: Coronary artery calcification is a cornerstone marker for coronary atherosclerosis. Therefore, the calculation of the coronary artery calcium score has become a routine method in diagnosing coronary artery disease in recent years. Monocyte to high-density lipoprotein cholesterol ratio reflects proatherogenic and antiatherogenic balance, and this ratio is associated with coronary atherosclerosis and cardiovascular events. This study aimed to investigate the value of monocyte to high-densitylipoprotein cholesterol ratio in predicting coronary atherosclerosis, which coronary artery calcium score determines. METHODS: A total of 276 patients with chest pain who underwent coronary computed tomography angiography were enrolled in the study. The patients were divided into 3 groups according to coronary artery calcium score [coronary artery calcium score=0 for very low risk (n=121), coronary artery calcium score=1-99 for low risk (n=100), coronary artery calcium score ≥ 100 for moderate-high risk (n=55)]. The monocyte to high-density lipoprotein cholesterol ratio, neutrophil-to-lymphocyte ratio, systemic immune-inflammation index, and plateletto-lymphocyte ratio were calculated from venous blood samples. RESULTS: Monocyte to high-density lipoprotein cholesterol ratio values were significantly higher in patients with moderate-high coronary artery calcium score (1.29 ± 0.59 vs 1.41 ± 0.56 vs 1.56 ± 0.58, P =.009). However, there were no differences between the groups in terms of other inflammatory markers (neutrophil-to-lymphocyte ratio, systemic immune-inflammation index, and platelet-to-lymphocyte ratio). Age (odds ratio: 1.178; 95% CI: 1.107-1.253; P < .001), dyslipidemia (odds ratio: 14.252; 95% CI: 5.459-37.211; P <.001), smoking (odds ratio: 2.893; 95% CI: 1.317-6.358; P=.008), and monocyte to high-density lipoprotein cholesterol ratio (odds ratio: 2.082 per 1-point increase; 95% CI: 1.016-4.268; P=.045) were independent predictors of coronary artery calcium score in multivariate analysis. CONCLUSION: Our data showed that high monocyte to high-density lipoprotein cholesterol ratio is significantly associated with increased coronary artery calcium score. Monocyte to highdensity lipoprotein cholesterol ratio indicates that it can be applied easily and swiftly in clinics to help predicting the coronary artery disease.

RESUMEN

BACKGROUND: The relationship between small pericardial effusion (SPE) and outcomes has not been well studied in patients with heart failure. Therefore, we aimed to investigate the prevalence and importance of SPE in acute heart failure (AHF). METHODS: A total of 398 hospitalized patients with AHF were retrospectively reviewed. Patients' baseline demographic, clinical, echocardiographic, and laboratory characteristics were noted. SPE was defined as the presence of a pericardial effusion <10 mm. The primary outcome was one-year mortality. RESULTS: SPE was noted in 54 (13.6%) of the patients. Mortality at one year was greater for patients with a small effusion compared with those without SPE (44.4 vs. 11.4%, respectively; p < 0.001), and the one-year mortality rate for the whole group was 15.8%. Age (HR = 1.12, 95% CI 1.054-1.854, p = 0.024), N-terminal pro-B-type natriuretic peptide >4800 pg/ml (HR = 1.628, 95% CI 01.102-4.805, p = 0.001), left ventricular ejection fraction <30% (HR = 1.878, 95% CI 1.154-4.524, p = 0.001), and presence of SPE (HR = 1.567, 95% CI 1.122-2.991, p = 0.005) were independent predictors of one-year mortality on multivariate analysis. CONCLUSIONS: The presence of SPE on admission was an independent predictor of one-year mortality in AHF.

RESUMEN

BACKGROUND: The potential effects of cardiovascular comorbidities on the clinical outcomes in severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection remain unclear. Identification of the coronary and non-coronary cardiovascular findings may help to stratify the patients' prognosis. Therefore, we aimed to evaluate the prognostic impact of the coronary and the non-coronary cardiovascular findings in SARS-CoV-2 patients. METHODS: We studied a total of 594 SARS-CoV-2 patients who were hospitalized and performed a non-cardiac gated thoracic computed tomography. Two blinded radiologists assessed the coronary artery calcification segment involvement score (CACSIS) and non-coronary atherosclerosis cardiovascular findings (NCACVF). The baseline characteristics of the patients and CT findings were evaluated according to survival status. Logistic regression analyses were performed to identify the independent predictors of mortality. RESULTS: At a mean follow-up of 8 (4-12.5) days, 44 deaths occurred (7.4%). Compared to survivors, non-survivors had increased CACSIS [27.3% (CACSIS = 0) vs 25% (CACSIS 1-5) vs 47.7% (CACSIS >5), p < 0.001]. Similarly, on NCACVF, non-survivors had much more major findings compared to survivors (29.5% vs. 2.7%, respectively, p < 0.001). At multivariable analysis, age (p = 0.009), creatinine (p < 0.001), hs-cTnI (p = 0.004) and NCACVF (HR 1.789; 95% CI 1.053-3.037; p = 0.031) maintained a significant independent association with in-hospital mortality. CONCLUSION: Our study shows that coronary and non-coronary cardiovascular findings on non-cardiac gated thoracic CT may help to predict mortality in patients with SARS-CoV-2 infection.
