Heart Attack Risks and Prevention
Understanding Heart Attacks
- The leading cause of natural death globally is heart attacks, which predominantly affect men but also increasingly impact women post-menopause.
- Risk factors include obesity, diabetes, high blood pressure, high cholesterol levels, sedentary lifestyle, smoking habits, and poor diet (high in fats and low in fruits/vegetables).
Recognizing Symptoms and Causes
- Each individual should recognize their risk factors and take preventive measures; awareness can significantly reduce the likelihood of a heart attack.
- Annually, approximately 7.5 million people die from heart attacks due to the obstruction of coronary arteries that prevents oxygen-rich blood from reaching the heart.
Mechanisms Behind Heart Attacks
- The blockage often results from atherosclerosis (fat deposits in artery walls), but can also be linked to arrhythmias or toxic substances like cocaine.
