Medical experts are issuing warnings regarding subtle cardiovascular symptoms that are frequently misidentified as fatigue, stress, or aging.

Initial reports from the Institute of Cardiology at Bach Mai Hospital highlight that heart valve disease—including stenosis and regurgitation—can manifest through shortness of breath, persistent fatigue, and the necessity of sleeping with the head elevated. Advanced symptoms may include leg swelling, palpitations, or fainting.

Subsequent medical guidance emphasizes that heart attack warning signs can be equally deceptive. Rather than intense pain, chest discomfort may present as pressure, tightness, or a burning sensation that radiates to the shoulders, neck, or jaw. Experts note that these episodes can be short-lived, sometimes lasting only five to ten minutes, which often leads individuals to delay seeking professional medical evaluation.
