疲劳是女性心脏病发作的常见症状，但往往被轻视或误诊。1研究表明，最多70%的女性心脏病患者会出现疲劳症状，这是由于流向心脏的血流量下降导致心脏变得僵硬且工作异常。1
女性与男性在心脏病发作症状上存在显著差异。1女性比男性更可能在心脏病发作前数天甚至数周内经历一系列警告信号，1这在一定程度上源于女性更容易患上微血管疾病，而男性则更常见阻塞性冠状动脉病。1与正常疲劳不同，心脏相关疲劳具有明显特征：持久、无法通过睡眠改善、与身体劳动相关、可能持续数天或数周。1
除疲劳外，女性还应警惕其他心脏病发作症状。1这些症状包括胸部不适、下颌、颈部或背部疼痛、呼吸急促、恶心或呕吐、消化不良或烧心、异常出汗、睡眠中断以及头晕或头昏眼花。1
Fatigue stands as one of the most commonly dismissed symptoms of heart attack in women, despite affecting up to 70 percent of female cardiac patients 1. This symptom frequently goes unrecognized because it differs markedly from the more prominent chest pain that typically signals heart attacks in men 1. The underlying cause stems from reduced blood flow to the heart, which causes the organ to become stiffened and function abnormally 1.
Women tend to experience a broader array of warning signals in the days or even weeks preceding a heart attack compared to their male counterparts 1. This difference in symptom presentation partly reflects the distinct cardiovascular conditions affecting each gender: women are more susceptible to microvascular disease, while men more commonly develop obstructive coronary artery disease 1. Heart-related fatigue carries specific characteristics that distinguish it from ordinary tiredness—it persists despite adequate rest, cannot be improved through sleep, intensifies with physical exertion, and may extend over days or weeks 1.
Beyond fatigue, women experiencing a heart attack should remain alert to additional warning symptoms including chest discomfort, pain in the jaw, neck or back, shortness of breath, nausea or vomiting, indigestion or heartburn, excessive sweating, sleep disturbances, dizziness, and lightheadedness 1. Recognizing this broader spectrum of symptoms is essential, as early identification can be lifesaving for women at risk of cardiac events 1.
