心脏是人体的‘发动机’，一旦出现异常，往往会发出一些早期信号。了解这些‘求救信号’，有助于及时干预，避免严重后果。首先，胸痛或胸部压迫感是最典型的心脏警报，尤其在体力活动或情绪激动时加重，休息后可能缓解。其次，不明原因的呼吸急促，尤其是在平躺时更明显，可能是心力衰竭的早期表现。第三，持续疲劳、乏力，尤其是女性，在心脏病发作前常感到极度疲倦，容易被误认为是压力大或睡眠不足。此外，心悸（心跳过快、过慢或不规则）、头晕甚至晕厥，也可能是心律失常或供血不足的表现。还有些人会出现左肩、背部、颈部或下颌的放射性疼痛，这种‘牵涉痛’容易被忽视。最后，夜间频繁起夜、脚踝或腿部水肿、食欲下降等，也可能是心脏功能减退的间接征兆。如果出现上述症状，尤其是多种症状同时存在，应及时就医，进行心电图、心脏超声等检查，切勿掉以轻心。
The heart is the body’s ‘engine,’ and when something goes wrong, it often sends early warning signals. Recognizing these signs can lead to timely intervention and prevent serious complications. First, chest pain or a feeling of pressure—especially worsening during physical exertion or emotional stress and easing with rest—is the most classic cardiac red flag. Second, unexplained shortness of breath, particularly when lying flat, may indicate early heart failure. Third, persistent fatigue or unusual exhaustion—especially common in women before a heart attack—is often mistaken for stress or lack of sleep. Additionally, palpitations (abnormally fast, slow, or irregular heartbeat), dizziness, or even fainting can signal arrhythmias or inadequate blood supply. Some people also experience radiating pain in the left shoulder, back, neck, or jaw—a type of referred pain that’s easily overlooked. Finally, indirect signs like frequent nighttime urination, swelling in the ankles or legs, and reduced appetite may point to declining heart function. If any of these symptoms appear—especially in combination—seek medical attention promptly for tests such as an ECG or echocardiogram. Never ignore these potential cries for help from your heart.
