Heart attacks are often viewed as sudden occurrences, but they stem from a prolonged process involving arterial damage and plaque accumulation. Dr. Asseem Dhall, director of cardiac sciences at ISIC Multispecialty Hospital, highlights that this process can begin as early as a person's twenties, driven by factors such as high blood pressure, high cholesterol, smoking, and uncontrolled blood sugar. As arteries become narrowed due to plaque buildup, many individuals remain asymptomatic until a heart attack occurs. The critical moment arises when soft plaque ruptures, leading to clot formation that can block blood flow, even if the artery isn't fully obstructed. Warning signs, such as unexplained fatigue, chest pain during exertion, and shortness of breath, should not be ignored. To prevent heart attacks, individuals are advised to manage their blood pressure and cholesterol levels, engage in regular exercise, eat a balanced diet, and avoid smoking. Monitoring heart health is essential for early intervention.
