Frequently Asked Questions About Heart Failure
Heart failure occurs when the heart muscle cannot pump blood efficiently enough to meet the body's needs. It doesn't mean the heart has stopped — rather, it's working less effectively. Common causes include coronary artery disease, high blood pressure, and previous heart attacks.
- Ischemic Cardiomyopathy: Caused by narrowed coronary arteries reducing blood flow to heart muscle.
- Dilated Cardiomyopathy: The left ventricle becomes enlarged and weakened, reducing pumping ability.
- Restrictive Cardiomyopathy: Heart muscle becomes stiff and rigid, limiting its ability to fill with blood between beats.
Yes. Depending on the underlying cause, surgical options include CABG (if caused by blocked arteries), valve repair/replacement, ventricular assist devices (VADs), and heart transplant for end-stage heart failure. Many patients also benefit from cardiac resynchronization therapy (CRT) devices.
