RESUMEN

OBJECTIVES: Cardiovascular diseases are also considered to increase the risk of death in COVID-19 patients. However, real-world data concerning the risk factors for death in patients with severe COVID-19 still remain vague. This study aimed to identify the potential risk factors associated with mortality in severe COVID-19 patients. METHODS: All consecutive patients admitted to the intensive care unit (ICU) of our institute for COVID-19 for severe COVID-19 pneumonia from April 1, 2020 to July 20, 2020 were included in the analysis. Patient characteristics, including complete medical history and comorbid diseases, blood test results during admission and on day 7, and clinical characteristics were compared between survivors and nonsurvivors. RESULTS: There was no significant difference between survivors and nonsurvivors regarding age, gender, and preexisting cardiovascular diseases. Moreover, the rate of the medications including angiotensin-converting enzyme (ACE) inhibitor and angiotensin receptor blockers did not differ between survivors and nonsurvivors. The peak C-reactive protein (CRP), procalcitonin, fibrinogen, and d-dimer levels and the rate for chronic renal failure were significantly higher in nonsurvivors compared with survivors. Intubated patients had a higher risk of death than the others had. CONCLUSIONS: This study failed to demonstrate a significant difference in preexisting cardiovascular diseases and cardiovascular medications between survivors and nonsurvivors who were admitted to ICU for severe COVID-19. Our findings indicate that the presence of chronic renal failure, a high peak ferritin concentration, and the need for invasive mechanical ventilation appear predictive for mortality. We propose that these risk factors should be taken into account in defining the risk status of severe COVID-19 patients admitted to the ICU.

RESUMEN

Epicardial fat thickness (EFT) is associated with aortic stiffness in diabetic patients. In this study, we aimed to determine if there is an association among the parameters of EFT, aortic velocity propagation (AVP), and carotid intima-media thickness (CIMT) in patients with non-insulin dependent diabetes mellitus. This study included 55 non-insulin dependent diabetes mellitus patients and 40 non-diabetic control patients. For all participants, EFT and AVP were determined by echocardiographic method and CIMT was calculated using an ultrasonographic exam. The EFT and CIMT values were found to be significantly increased in the non-insulin dependent diabetes mellitus group. On the other hand, aortic velocity propagation was decreased in the non-insulin dependent diabetes mellitus group compared to non-diabetic patients (EFT; 8.43 ± 1.68 versus 6.36 ± 2.21 mm, p < 0.001; CIMT; 0.92 ± 0.24 versus 0.58 ± 0.18 mm, p < 0.001; and AVP; 28.20 ± 16.02 versus 58.10 ± 17.50, p < 0.01, respectively). Significantly higher EFT and CIMT values were found in addition to lower AVP values in non-insulin dependent diabetes mellitus patients. Moreover, we demonstrated that there was a strong correlation between EFT, CIMT, and AVP.

RESUMEN

OBJECTIVE: Monocyte count to HDL-C Ratio (MHR) and Fibrinogen to Albumin Ratio (FAR) have recently emerged as markers of inflammation in atherosclerotic diseases. Our goal was to investigate the relationships of MHR and FAR with the severity of carotid artery stenosis (CAS) in patients with asymptomatic carotid artery disease. METHODS: This retrospective study consisted of 300 patients with asymptomatic CAS. Pre-angiographic MHR, FAR, and high-sensitive C-reactive protein (hsCRP) were measured. Carotid angiography was performed in patients with ≥50% stenosis on carotid ultrasonography. Patients were first split into 2 groups based on the degree of CAS and then tertiles (T) of MHR. RESULTS: 96 patients had clinically insignificant CAS (<50%) (Group-1), and 204 patients had clinically significant CAS (≥50%) (Group-2). Group-2 had higher MHR, FAR, and hsCRP than group-1. Patients in T3 had higher MHR, FAR, and hsCRP than in T1 and T2. MHR, FAR, and hsCRP were correlated with each other (p<0.001, for all). MHR, FAR, and hsCRP were independent predictors of significant CAS. MHR better predicted a significant CAS than FAR and hsCRP (p<0.05). CONCLUSION: Pre-angiographic MHR may be a better predictor than FAR and hsCRP in identifying a clinically significant carotid stenosis in patients with asymptomatic CAS. Patients with asymptomatic CAS and a high level of MHR should be followed-up closely to supervise risk-factor control and intensify treatment.

RESUMO OBJETIVO Recentemente, a contagem de monócitos para a proporção HDL-C (MHR) e a relação fibrinogênio para albumina (FAR) emergiram como marcadores de inflamação em doenças ateroscleróticas. Nosso objetivo é investigar a relação da MHR e FAR com a gravidade da estenose da artéria carótida (CAS) em pacientes com doença assintomática da artéria carótida. MÉTODOS Este estudo retrospectivo incluiu 300 pacientes com CAS assintomática. MHR pré-angiográfica, FAR e proteína C reativa de alta sensibilidade (hsCRP) foram medidas. A angiografia carotídea foi realizada em pacientes com estenose ≥50% na ultrassonografia carotídea. Os pacientes foram primeiramente divididos em dois grupos com base no grau de CAS e depois nos tercis (T) da MHR. RESULTADOS Noventa e seis pacientes apresentaram um CAS clinicamente insignificante (<50%) (grupo 1) e 204 pacientes apresentaram CAS clinicamente significativo (≥50%) (grupo 2). O grupo 2 apresentou MHR, FAR e hsCRP superior ao grupo 1. Pacientes em T3 apresentaram maior MHR, FAR e hsCRP do que em T1 e T2. MHR, FAR e hsCRP foram correlacionados entre si (p<0,001, para todos). MHR, FAR e hsCRP foram preditores independentes de CAS significativa. MHR predisse melhor uma CAS significativa que FAR e hsCRP (p<0,05). CONCLUSÕES A MHR pré-angiográfica pode ser um melhor preditor que a FAR e a hsCRP na identificação de estenose carotídea clinicamente significativa em pacientes com CAS assintomática. Pacientes com CAS assintomática e alto nível de MHR devem ser acompanhados de perto para supervisionar o controle dos fatores de risco e intensificar o tratamento.
