KK passed away last year on May 31 at the age of 53. He died while performing at a concert in Kolkata on May 31. A later autopsy revealed cited myocardial infarction (heart attack) as the probable cause of death. Notably, he had previous heart conditions, including 80% blockage of his heart.What Is A Heart Attack?A heart attack occurs when blood flow to a part of the heart muscle is blocked, typically by a blood clot in a coronary artery. This blockage prevents oxygen-rich blood from reaching that part of the heart muscle, causing damage or eventual death of that muscle tissue.Common symptoms include chest pain or discomfort, shortness of breath, nausea, sweating, and pain in the arm, back, or jaw. Symptoms can vary and may be less obvious in some individuals.Treatment for a heart attack often involves medications to dissolve the clot, restore blood flow, or prevent further clots, along with procedures like angioplasty or stenting. Lifestyle changes and cardiac rehabilitation are also recommended for recovery.How Can You Prevent Heart EmergenciesBoth heart attack and cardiac arrest can be caused due to Coronary or ischemic heart disease (CHD). Therefore, it is pivotal to maintain good heart health. Following are the precautionary tips you can use to prevent CHD, as per World Health Organization (WHO).Adopt a Heart-Healthy Diet: Focus on a diet rich in fruits, vegetables, whole grains, legumes, and nuts. Reduce intake of salty meats, processed foods, and sugary snacks. Opt for natural seasonings like calamansi juice and vinegar instead of high-sodium condiments, and drink water instead of sweetened beverages.Manage Your Weight: Achieve and maintain a healthy weight by aiming for a BMI below 25 and reducing central obesity. Cutting 500 calories from your daily intake can help you lose about half to one kilogram per week.Increase Physical Activity: Aim for at least 150 minutes of moderate exercise per week, such as brisk walking or gardening. Regular physical activity helps manage blood pressure, cholesterol, and weight.Avoid Tobacco: Refrain from smoking and exposure to second-hand smoke. Quitting tobacco reduces your risk of heart disease significantly over time.Limit Alcohol Consumption: Although occasional drinking is common, avoid alcohol entirely to minimize cardiovascular risk. There is no safe level of alcohol consumption for heart health.Monitor Blood Pressure and Sugar Levels: Regularly check your blood pressure and blood sugar with a healthcare provider. Unchecked high blood pressure can damage your heart. If diagnosed with hypertension or diabetes, adhere to your treatment plan and involve your loved ones in your health journey.
