UNC Researchers Find Increase in Comorbidities among Hospitalized Patients with Heart Failure

A study recently published in the journal Circulation looks at temporal trends in the burden of comorbidities and associated risk of mortality among patients with heart failure (HF) with preserved ejection fraction (HFpEF), in which the left ventricle of the heart is not able to relax enough to fill properly with blood, and HF with reduced ejection fraction (HFrEF), in which the left ventricle is not able contract enough to pump out as much blood.
