Core Viewpoint - The article discusses the risks associated with sudden intense physical activity, particularly for individuals with underlying heart conditions, as illustrated by two cases of acute myocardial infarction in 38-year-old fathers after engaging in sports activities. Group 1: Incidents and Medical Analysis - Two 38-year-old fathers experienced acute myocardial infarction after engaging in intense physical activity, specifically playing badminton for about 10 minutes, leading to severe chest pain and hospitalization [1] - Medical experts indicate that intense exercise can lead to the rupture of unstable plaques in the heart, resulting in significant coronary artery blockage [1] Group 2: Risk Factors and Recommendations - Individuals with pre-existing heart conditions or risk factors should avoid sudden and intense exercise, as it can trigger acute myocardial infarction [6] - Recommendations for preventing exercise-induced heart issues include: 1. Conducting cardiovascular risk screenings annually, especially for those with a family history of heart disease or other risk factors [8] 2. Planning a gradual exercise regimen, starting with low-intensity activities and progressively increasing intensity [9] 3. Preparing adequately before and after exercise to avoid sudden stress on the heart [9]
