Varanasi: With changing lifestyle and poor socio-economic factors, there is a rapid increase in the number of patients living with ischemic heart disease. Acute Coronary Syndrome (ACS) or commonly known as heart attack, is one of the leading deadly disease in developing countries like India. Over 20% of the population especially above the age of 40 years are developing several cardiac ailments. “Recently, more people in their 20s, 30s and 40s have been suffering from heart ailments. The increasing stress of modern life has exposed even younger people to the risk of heart diseases. While a person’s genetic disposition and family history remain the most common and uncontrollable risk factors, majority of heart diseases in the younger generation is due to excessive stress and long working hours coupled with erratic sleep patterns, which cause inflammation and increase the risk of heart disease. Smoking and a sedentary lifestyle further accelerate the risk symptoms in people in the age group of 20 to 30 years.” Said Dr. Viveka Kumar, Sr. Director – Cath Lab, Max Super Speciality Hospital, Saket Heart attack or ACS is an acute manifestation of ischemic heart disease whereby, there is a sudden interruption in the blood supply of heart muscle due to blockage of coronary arteries. This interrupts the supply of oxygen and nutrients to the heart muscle and the muscle dies eventually if the blood supply is not restored immediately. However, Symptoms of heart attack vary in different patients and some patients can have unusual symptoms like hiccups. The pain may also vary from mild to very severe pain. Sometimes, the first sign may be sudden cardiac arrest manifested by sudden collapse of the patient. The earliest warning might be recurrent chest pain or pressure (angina) that’s triggered by exertion and relieved by rest. Angina is caused by a temporary decrease in blood flow to the heart.
