Core Viewpoint - The article emphasizes the increasing incidence of acute myocardial infarction (heart attack) during the cold season, particularly highlighting the need for awareness among younger individuals as the average age of onset continues to decrease [1]. Group 1: Risk Factors for Myocardial Infarction - Unhealthy lifestyle choices such as binge eating, excessive intake of high-fat and high-calorie foods, and alcohol consumption can lead to increased blood lipid levels and blood viscosity, raising the risk of heart attack [2]. - Emotional stress, such as anger and extreme emotions, can double the risk of heart attack compared to normal emotional states [3]. - Chronic fatigue and prolonged stress can lead to elevated cortisol levels, increasing blood pressure and exacerbating coronary heart disease [4]. - Research indicates that individuals who sleep only five hours a night have a 40% higher risk of myocardial infarction compared to those who sleep eight hours [5]. - Sudden temperature changes during autumn and winter can trigger acute myocardial infarction due to significant blood vessel constriction [6]. Group 2: Warning Signs of Myocardial Infarction - Chest discomfort is a common precursor, often described as pressure, tightness, or dull pain that may last for several minutes [8]. - Pain or discomfort may radiate to the upper body, including shoulders, arms, back, neck, or jaw, particularly on the left side [9]. - Shortness of breath can occur without obvious physical activity and may worsen when lying down [10]. - Gastrointestinal discomfort, such as upper abdominal pain, nausea, or heartburn, is more common in female patients and can be mistaken for gastrointestinal issues [11]. - Sudden extreme fatigue or weakness, even with minimal activity, can be a significant warning sign [12]. - Autonomic symptoms like cold sweat, dizziness, or palpitations may also indicate an impending heart attack [13]. Group 3: Emergency Response to Myocardial Infarction - Immediate action includes calling emergency services and ensuring the patient stops all activities, sitting or lying down quietly [14]. - If chest pain persists for more than 15 minutes, nitroglycerin may be administered, but blood pressure should be checked first [14]. - In cases of cardiac arrest, prompt CPR should be initiated until emergency help arrives, as the critical window for effective intervention is approximately two hours [15]. - Recognizing bodily signals and maintaining heart health through good lifestyle habits are crucial for preventing heart attacks [16].
