Heart disease includes many diseases that affect your heart, but coronary artery disease (CAD) is the most common and familiar one. Heart disease can lead to a heart attack, heart failure, cardiac arrest, stroke and organ damage. Healthy habits, medicines and procedures can prevent or treat CAD and other heart diseases.
š«Coronary artery disease: Fatty deposits make your heartās blood vessels narrow.
š«Arrhythmias: Abnormal heart rhythms keep your heart from beating in a coordinated way.
š«Heart valve diseases: Valves that are too narrow or donāt close right reduce blood flow.
š«Cardiomyopathy: Stiff or thickened heart muscle canāt pump blood well.
Heart failure: Your heart canāt pump blood well enough to keep up with your bodyās needs.
š«Congenital heart disease: Problems with how your heart formed before birth prevent normal blood flow.
š«Pericardial issues: A stiff or inflamed sac (pericardium) around your heart presses on your heart.
The first symptoms of heart disease include chest pain, shortness of breath, swelling in your legs, fatigue and dizziness/fainting. But you can have different signs of heart disease depending on whatās wrong. Heart disease symptoms may include:
Pounding or racing heart (palpitations)
Sweating
