专家：心梗症状不可忽视 需熟记两个“120”

Core Viewpoint - The incidence of acute myocardial infarction (AMI) is increasing among individuals under 45 years old, with various risk factors contributing to this trend, emphasizing the importance of early detection and treatment [1][3]. Group 1: Symptoms and Case Study - Typical symptoms of AMI include severe squeezing pain in the chest, which may radiate to the left arm, jaw, neck, back, or shoulder, often accompanied by nausea, vomiting, sweating, or difficulty breathing [1]. - A case study of a patient, Mr. Zhang, illustrates the dangers of ignoring symptoms; despite experiencing chest pain and arm numbness, he delayed seeking treatment until he suffered a heart attack [2]. Group 2: Importance of Early Treatment - Early treatment is crucial for AMI patients, with a critical time frame of 120 minutes from the onset of symptoms to restore blood flow and reduce mortality and disability rates [2]. - The medical team performed emergency procedures including thrombectomy, balloon dilation, and stent placement to restore blood flow in Mr. Zhang's case [2]. Group 3: Risk Factors and Prevention - Key risk factors for AMI include age, hypertension, hyperlipidemia, diabetes, and obesity, while lifestyle factors such as irregular schedules, excessive fatigue, sedentary behavior, smoking, and alcohol consumption contribute to the rising incidence among younger populations [3]. - Self-rescue measures for suspected AMI include calling emergency services, resting in a position that allows for easy access for responders, and taking sublingual nitroglycerin to alleviate symptoms [3].
