The human heart is one of the most important organs that beats approximately 72 times per minute. It pumps blood throughout the body, carrying vital materials and removing waste. A heart attack occurs suddenly when plaque builds up in the arteries from conditions like high blood pressure, cholesterol, smoking, obesity, and diabetes. Researchers found that heart disease is increasing in India, with half of all heart attacks in Indian men occurring before age 50. Regular walking and exercise can help improve heart health and reduce risks.
