Core Viewpoint - The recent death of Zhao Han, founder of the well-known Yunnan cuisine brand "Yunhaiyao," due to a sudden heart attack has raised awareness about the increasing prevalence of acute myocardial infarction (AMI) among younger individuals and the need for public education on heart health and self-rescue measures [1][4]. Group 1: Heart Attack Awareness - Acute myocardial infarction (AMI) is characterized by the acute necrosis of heart muscle cells due to insufficient blood supply, primarily caused by the blockage of coronary arteries [2][3]. - The overall mortality rate from AMI in China has shown an upward trend from 2002 to 2021, with rural areas experiencing a significant increase since 2012, surpassing urban rates [1]. Group 2: Risk Factors and Symptoms - Key risk factors for heart attacks include chronic conditions such as hypertension, hyperlipidemia, and diabetes, as well as lifestyle choices like smoking, obesity, and lack of exercise [2][4]. - Symptoms of a heart attack may include sudden discomfort in the chest, severe pain radiating to the left shoulder and arm, shortness of breath, sweating, and feelings of impending doom [3][5]. Group 3: Emergency Response and Prevention - Immediate self-rescue measures include stopping all activities, resting, calling emergency services, and using emergency medications like nitroglycerin or aspirin if symptoms persist [3][5]. - Preventive measures against sudden cardiac death involve regular health screenings, lifestyle modifications such as a low-salt, low-fat diet, regular exercise, and managing existing health conditions [6].
