Core Viewpoint - Stroke, commonly known as cerebrovascular accident, is a leading cause of death and disability among residents in China, with high temperatures also posing a significant risk for stroke occurrence [1][2]. Group 1: Stroke Types and Risks - Stroke is categorized into ischemic and hemorrhagic types, with acute ischemic stroke (acute cerebral infarction) accounting for approximately 70% of cases [3]. - High temperatures, particularly above 32°C, significantly increase the risk of stroke, with the danger escalating as temperatures rise [1][4]. Group 2: Factors Contributing to Stroke in High Temperatures - Dehydration: High temperatures lead to excessive sweating and fluid loss, increasing blood viscosity and slowing blood flow, which raises the risk of ischemic stroke [4]. - Blood Pressure Fluctuations: Heat causes blood vessels to dilate, potentially lowering blood pressure, but can also lead to erratic blood pressure changes due to environmental stressors, increasing the risk of hemorrhagic stroke [4]. - Thermoregulation Burden: The body's effort to cool down increases heart rate and cardiac workload, which may affect cerebral blood supply [4]. Group 3: Recognizing and Responding to Stroke - Early warning signs include dizziness and limb numbness, which are critical indicators of a potential stroke [5]. - The "120 Rule" for quick identification of stroke symptoms involves observing facial symmetry, checking arm strength, and listening for clear speech [6]. Group 4: Common Missteps in Emergency Response - Avoid moving the patient abruptly, as this can worsen bleeding [8]. - Do not shout at the patient, as loud noises can elevate blood pressure and exacerbate the condition [9]. - Refrain from administering medication without a clear diagnosis, as incorrect medication can worsen symptoms [10]. - Do not feed or give drinks to the patient, as this can lead to choking and interfere with timely medical intervention [11]. Group 5: Misconceptions about Stroke Treatment - Immediate medical attention is crucial, and the golden window for effective treatment is within 4.5 hours of symptom onset [13]. - It is a misconception that stroke patients should be taken to distant hospitals; local hospitals can often provide adequate emergency care [13]. - Young and middle-aged individuals are also at risk for stroke due to unhealthy lifestyles, including hypertension and obesity [15].
