Heart disease is one of India's biggest public-health threats. The steep increase in heart attacks among Indians below 45 years is of grave concern. In particular, the occurrence of lesions or blockage in the heart vessels due to deposits of fat, cholesterol, platelets, and calcium has become a common cardiac ailment. It impedes blood flow and if left untreated could result in myocardial infarction (heart attack). This condition, also known as Coronary Artery Disease (CAD), is the leading cause of death in the world. Symptoms could range from chest pain, palpitation or dizziness to none at all. Several causes could lead to these heart blocks including being overweight, smoking, hypertension, diabetes, physical exertion and stress.
