What are the Causes of cardiac failure?

Cardiac failure, or heart failure, can be caused by a variety of factors, including coronary artery disease, hypertension, and previous heart attacks, which damage the heart muscle. Other contributors include conditions like Diabetes, obesity, and certain valvular Heart diseases. Lifestyle factors such as smoking, excessive alcohol consumption, and lack of physical activity can also increase the risk. Additionally, certain chronic conditions, such as thyroid disorders and anemia, may exacerbate heart failure.
