Hi everyone...
Virus infections are the most common cause of myocarditis. The previous severe acute respiratory syndrome (SARS) beta-coronavirus SARS-CoV-1 was associated with tachyarrhythmias, signs, and symptoms of heart failure.
Let's learn about SARS-CoV-2:
Let's learn about SARS-CoV-2:
- COVID-19 patients who died had higher levels of troponin, myoglobin, C-reactive protein, serum ferritin, and IL-6.
- This is because of the high inflammatory burden in COVID-19.
Let’s find out and understand about CVS complications by COVID-19:
- Mainly, vascular inflammation, myocarditis, and cardiac arrhythmias
- The possible late phenomenon of the viral respiratory infection
- Commonly observed in severe cases
- Strongly associated with mortality
Cardiovascular complications of COVID-19 |
Cardiac MRI Findings in COVID-19:
- ⬆️ Wall thickness with diffuse biventricular hypokinesis (especially in the apical segments)
- Severe LV dysfunction (LVEF < 35%)
- Circumferential pericardial effusion ( notable around the right chambers)
- Marked biventricular myocardial interstitial edema
- Diffuse late gadolinium enhancement involving the entire biventricular wall
Patients who have high troponin levels showed a higher incidence of complications such as
- ARDS
- Malignant arrhythmias
- Acute renal injury
- Acute coagulopathy
Lastly, what are the major risk factors for COVID-19 mortality?
- advanced age (>60 years)
- male sex
Strong and independent risk factors:
- the presence of comorbidities ( HTN, coronary artery disease)
- cardiac injury, myocarditis, and ARDS
Thank you,
