What are 3 conditions that can cause heart failure?
Three conditions that can cause heart failure include coronary artery disease, which narrows the arteries and reduces blood flow to the heart; hypertension, or high blood pressure, which forces the heart to work harder; and cardiomyopathy, a disease of the heart muscle that affects its ability to pump effectively. Other contributing factors can include diabetes, arrhythmias, and previous heart attacks. These conditions can weaken the heart over time, leading to heart failure.
