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).

5 key predictors of heart failure hospitalizations after TAVR

Diabetes and atrial fibrillation are just some of the factors that can increase a patient's risk of being hospitalized for heart failure within one year of undergoing a successful TAVR procedure.

Impella Heart Pump Abiomed RECOVER IV RCT cardiogenic shock

Impella heart pumps boost survival up to 81% for cardiogenic shock patients

The heart pumps appear to provide significant benefits for patients with acute myocardial infarction- or myocarditis-related cardiogenic shock.

HFpEF patients with MR may face a higher mortality risk—but not if they have AFib

There is an established connection between MR and HFrEF, but we know much less about the link between MR and HFpEF. 

Cardiologists identify a potential new side effect of monkeypox: acute myocarditis

A 31-year-old patient developed acute myocarditis shortly after the onset of monkeypox symptoms. The team that treated him shared their story in a new case study.
