Heart disease

Heart disease, usually thought of as blockages in the arteries that can cause a heart attack, can describe any medical condition affecting your heart.

Long QT syndrome

Myocarditis

Sick sinus syndrome

Complications

Aortic valve regurgitation

Aortic valve stenosis

Diabetic ketoacidosis

Endocarditis

Heart attack

Heart failure

Low blood pressure (hypotension)

Low blood pressure (hypotension) can be a sign of good health or of a life-threatening condition. Find out more about hypotension's causes and treatment options.

Mitral valve regurgitation

Mitral valve stenosis

Myocardial ischemia

Pectus excavatum

Pericardial effusion

Premature ventricular contractions

Ventricular fibrillation

Risk factors

Cardiomyopathy

Coarctation of the aorta

Hyperparathyroidism

Panic attacks and panic disorder

Symptoms

Angina

Bradycardia

Chest pain

Heart murmurs

Heart palpitations

Heart palpitations are skipped, fluttering or racing heartbeats that aren't usually a symptom of a serious heart problem. Discover the causes and symptoms of this condition.
