Cardiology is a medical specialty and a branch of internal medicine concerned with disorders of the heart. It deals with the diagnosis and treatment of such conditions as congenital heart defects, coronary artery disease, electrophysiology, heart failure and valvular heart disease.
If a person has symptoms of a heart condition, their physician may refer them to a cardiologist.
Symptoms that can indicate a heart problem include:
- shortness of breath
- dizziness
- chest pains
- changes in heart rate or rhythm
- high blood pressure
A cardiologist can carry out tests for a heart murmur or an abnormal heart rhythm.
They often treat patients who have had a heart attack, heart failure, or other heart problems. They help make decisions about heart surgery, heart catheterization, and angioplasty and stenting.
Heart diseases that a cardiologist can help with include:
- atherosclerosis
- atrial fibrillation
- arrhythmias
- congenital heart disease
- coronary heart disease
- congestive heart disease
- high blood cholesterol and triglycerides
- hypertension
- pericarditis
- ventricular tachycardia
- high blood pressure, or hypertension
The cardiologist can give advice about preventing heart disease.
