Abstract
Background
Some studies have shown a higher prevalence of deaths in patients with cardiovascular risk factors (CRF) during hospitalization for COVID-19.
Objectives
To assess the impact of high cardiovascular risk in patients hospitalized in intensive care for COVID-19
Methods
Retrospective study with patients admitted to an intensive care unit, with a diagnosis of COVID-19 confirmed by RT-PCR, and with at least one troponin measurement during hospitalization. The criteria for defining high cardiovascular risk (HCR) patients were: history of established cardiovascular disease (myocardial infarction, stroke, or peripheral arterial disease), diabetes, chronic kidney disease with clearance 65 years). The primary outcome of this study is all-cause in-hospital mortality. P<0.05 was considered significant.
Results
This study included 236 patients, mean age = 61.14±16.2 years, with 63.1% men, 55.5% hypertensive, and 33.1% diabetic; 47.4% of the patients also presented HCR. A significant increase in mortality was observed as the number of risk factors increased (0 FRC: 5.9%; 1 FRC: 17.5%; 2 FRC: 32.2% and ≥3 FRC: 41.2%; p=0.001). In the logistic regression adjusted for severity (SAPS3 score), the HCR and myocardial injury group had a higher occurrence of in-hospital mortality (OR 40.38; 95% CI 11.78-138.39). Patients without HCR but with myocardial injury also exhibited a significant association with the primary outcome (OR 16.7; 95% CI 4.45-62.74).
Conclusion
In patients hospitalized in intensive care for COVID-19, HCR impacts in-hospital mortality only in patients with myocardial injury.
