What Is Heart Disease?
Heart disease refers to a group of conditions that affect the heart and its ability to work properly. These conditions can affect the heart’s blood vessels, muscles, valves, or electrical rhythm.
Common types include coronary artery disease, arrhythmias, heart valve disease, heart failure, and cardiomyopathy. Risk factors such as high blood pressure, high cholesterol, diabetes, smoking, physical inactivity, and family history can increase the risk of developing certain heart conditions.
Recognizing symptoms and understanding your risk can help you seek medical care at the right time.
