Insights
The Omicron variant caused record COVID-19 hospitalizations, with cardiac injury affecting over 20% of patients. Understanding these cardiac complications is crucial for reducing COVID-19 mortality.
Area of Science:
- Cardiology
- Infectious Diseases
- Public Health
Background:
- The Omicron variant of COVID-19 has led to unprecedented hospitalizations globally.
- Cardiac complications are frequent in hospitalized COVID-19 patients, impacting dysrhythmias, troponin levels, myocarditis, heart failure, and thromboembolic events.
Purpose of the Study:
- To review the prevalence and mechanisms of cardiovascular injury caused by SARS-CoV-2 (the virus that causes COVID-19).
- To outline current treatment recommendations for hospitalized COVID-19 patients with cardiac involvement.
- To aid healthcare professionals in reducing morbidity and mortality associated with COVID-19 and post-COVID conditions.
Main Methods:
- Literature review focusing on COVID-19 and cardiovascular complications.
- Analysis of prevalence data for cardiac injury markers (troponin, dysrhythmias, myocarditis, heart failure, thromboembolism).
- Synthesis of risk factors and pathophysiologic mechanisms of SARS-CoV-2 cardiovascular injury.
Main Results:
- Cardiac injury affects at least 20% of hospitalized COVID-19 patients.
- Specific complications include cardiac dysrhythmias (17-44%), elevated troponin (22-40%), myocarditis (2-7%), heart failure (4-21%), and thromboembolic events (15-39%).
- Risk factors include advanced age, male sex, obesity, diabetes, pre-existing cardiovascular disease, and severe pneumonia.
Conclusions:
- COVID-19, particularly the Omicron variant, poses significant risks to the cardiovascular system.
- Prompt recognition and management of cardiac complications are essential for improving patient outcomes.
- Further research into SARS-CoV-2 cardiovascular pathophysiology and treatment is warranted.
Abstract:
603,711,760 confirmed cases of COVID-19 have been reported throughout the world and 6,484,136 individuals have died from complications of COVID-19 as of September 7, 2022. Significantly, the Omicron variant has produced the largest number of COVID-19 associated hospitalizations since the beginning of the pandemic. Cardiac injury occurs in ≥20% of the hospitalized patients with COVID-19 and is associated with cardiac dysrhythmias in 17 to 44%, cardiac injury with increases in blood troponin in 22 to 40%, myocarditis in 2 to 7%, heart failure in 4 to 21%, and thromboembolic events in 15 to 39%. Risk factors for cardiac complications include age >70 years, male sex, BMI ≥30 kg/m2, diabetes, pre-existing cardiovascular disease, and moderate to severe pneumonia at hospital presentation. Patients with prior cardiovascular disease who contract COVID-19 and experience a significant increase in their blood troponin concentration are at risk for mortality rates as high as 69%. This review focuses on the prevalence, the pathophysiologic mechanisms of CoV-2 injury to the cardiovascular system and the current recommended treatments in hospitalized patients with COVID-19 in order that medical personnel can decrease the morbidity and mortality of patients with COVID-19 and effectively treat patients with Covid and post Covid syndrome.
