Impact of myocardial injury on cardiovascular complications in hospitalized patients with COVID-19: insights from Latin America.

Introduction: Viral infection by SARS-CoV2 is a pandemic affecting over 600 million people worldwide. One of five hospitalized patients may present myocardial injury, strongly associated with disease severity and mortality.

Methodology: Retrospective cross-sectional study of hospitalized COVID-19 patients diagnosed between May 01, 2020, and June 30, 2021, from the database of the Registro Latinoamericano de Enfermedad Cardiovascular y COVID-19 (CARDIO COVID 19-20) with a troponin value recorded during hospitalization.

Marked Global Differences in Mortality in Male Patients with COVID-19: An Analysis of the CARDIO COVID 19-20 and WHF COVID-19 CVD Studies.

Background: COVID-19 has led to nearly seven million deaths and male sex has been reported as one of the main risk factors for mortality. Few studies have analyzed cohorts of male patients, especially in underrepresented regions in the medical literature, such as low and middle-income nations. To address this gap, we conducted large-scale, male-specific, multinational analyses, to improve understanding of factors associated with mortality in this high-risk population and global variations.
