During the COVID-19 pandemic, it became clear that the disease had significant impacts on the heart. Patients were experiencing heart attacks, myocarditis, and elevated levels of troponin, a marker for cardiac damage. Even after recovering from COVID-19, many people developed lingering cardiovascular symptoms. The latest Omicron variant of the virus has also raised concerns about its potential effects on heart health. Doctors are now working to understand the underlying mechanisms and develop better treatments for COVID-19-related heart issues. Additionally, long COVID has been associated with postural orthostatic tachycardia syndrome (POTS), a condition that causes abnormal heart rates. Treatment strategies for long COVID focus on light exercise and endurance training to prevent further deterioration.
