Heart Failure

Heart failure occurs when the heart cannot pump as much blood as the body requires. This ineffective pumping can lead to enlargement of the heart as the myocardium works harder pump the same amount of blood. Heart failure may be caused by defects in the myocardium, such as an a heart attack infarct, or due to structural issues such as severe heart valve regurgitation. Heart failure can be divided into HF with preserved ejection fraction (HFpEF), and HF with reduced ejection fraction (HFrEF). The disease is further divided into four New York Heart Association (NYHA) classes. Stage IV heart failure is when the heart is completely failing and requires a heart transplant or hemodynamic support from a left ventricular assist device (LVAD).

Heart damage after COVID-19 vaccination extremely rare among adolescents

Vaccine-related myocarditis was seen in approximately 0.00005% of children between the ages of 12 and 15. All cases were mild, and the median length of stay at the hospital was three days. 

New evidence that heart damage risk is much higher after COVID-19 infection than after vaccination

The new meta-analysis, published in Frontiers in Cardiovascular Medicine, included data from 58 million patients. “We hope our findings will help mitigate vaccine hesitancy and increase vaccine uptake," one researcher said.
