Insights
Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection, causing COVID-19, can lead to heart damage. Males with pre-existing cardiovascular disease face higher risks of severe outcomes and death.
Area of Science:
- Cardiology
- Infectious Diseases
- Sex Differences in Medicine
Background:
- COVID-19, caused by SARS-CoV-2, often results in respiratory failure but significantly contributes to mortality via cardiovascular injury.
- Preexisting cardiovascular disease (CVD) is a major risk factor for severe COVID-19 outcomes, including hospitalization and death.
- COVID-19 pathogenesis can directly promote cardiovascular injury, exacerbating mortality risk.
Purpose of the Study:
- To review the basic science and clinical observations of cardiovascular injury in COVID-19.
- To explore the interplay between sex differences, pre-existing CVD, and COVID-19-related cardiac injury.
- To highlight the disproportionate risk observed in males with CVD.
Main Methods:
- Review of current clinical observations.
- Analysis of basic science perspectives on COVID-19 pathogenesis.
- Synthesis of data regarding sex differences in COVID-19 outcomes.
Main Results:
- Males with pre-existing CVD exhibit a higher risk of severe COVID-19 outcomes.
- COVID-19 infection can independently cause or worsen cardiovascular injury.
- Sex-based disparities in COVID-19 mortality are linked to CVD and cardiac injury.
Conclusions:
- Cardiovascular injury is a critical factor in COVID-19 mortality, particularly in males with pre-existing CVD.
- Understanding the mechanisms underlying sex differences in COVID-19 cardiac injury is crucial for risk stratification and management.
- Further research is needed to elucidate the complex interactions between sex, CVD, and SARS-CoV-2 infection.
Abstract:
The novel 2019 coronavirus disease (COVID-19), resulting from severe acute respiratory syndrome coronarvirus-2 (SARS-CoV-2) infection, typically leads to respiratory failure in severe cases; however, cardiovascular injury is reported to contribute to a substantial proportion of COVID-19 deaths. Preexisting cardiovascular disease (CVD) is among the most common risk factors for hospitalization and death in COVID-19 patients, and the pathogenic mechanisms of COVID-19 disease progression itself may promote the development of cardiovascular injury, increasing risk of in-hospital death. Sex differences in COVID-19 are becoming more apparent as mounting data indicate that males seem to be disproportionately at risk of severe COVID-19 outcome due to preexisting CVD and COVID-19-related cardiovascular injury. In this review, we will provide a basic science perspective on current clinical observations in this rapidly evolving field and discuss the interplay sex differences, preexisting CVD and COVID-19-related cardiac injury.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
