Description

Myocardial infarction (MI) is defined as death of myocardial tissue. When blood vessels that supply blood to the heart are blocked, preventing enough oxygen from getting to the heart and the heart muscle dies or becomes permanently damaged is known as Myocardial infarction (MI).Injury to the heart muscle causes chest pain and chest pressure sensation. If blood flow is not restored to the heart muscle within 20 to 40 minutes,irreversible death of the heart muscle will begin to occur. According to WHO Ischemic heart diseases are the most leading cause of mortality (15%) of all death in India. In US about 1.1 million cases occur every year with about 30% mortality and more than 50% of deaths occur on way to the hospital. In India, 31.7% of deaths occur due to MI. Incidence of cardiovascular diseases was about 7% in 1970 and increased up to 32% in 2011 in India Mortality estimates due to MI ranging from 10% in Meghalaya to 49% in Punjab Goa (42%), Tamil Nadu (36%) and Andhra Pradesh (31%) have the highest MI related mortality estimates.
