Cardiology is a branch of medicine dealing with disorders of the heart as well as parts of the circulatory system. Heart disease is the commonest cause of death in Malaysia today. Patients with heart disease usually complain of chest pain, shortness of breath, swelling of ankles or legs or blackouts. Another common disease seen by consultant cardiologists is hypertension or high blood pressure. Diseases of the heart can now be treated by medicine, surgery or by putting a thin wire in through a blood vessel in the groin or wrist and rectify the narrowing in the artery that supplies blood to the heart.
