10 Important Symptoms of a Heart Attack You Shouldn’t Ignore

Symptom #2 – Shortness of Breath

Shortness of breath, also known as dyspnea, is a critical symptom of a heart attack that can occur with or without chest pain. It often presents as a sudden, unexplained difficulty in breathing or feeling winded, even with minimal exertion. In some cases, shortness of breath may worsen when lying down and improve when sitting up.

This symptom occurs as the heart struggles to pump blood effectively, leading to a reduced supply of oxygen to the body’s tissues. As a result, the body works harder to obtain the necessary oxygen, causing the sensation of breathlessness. It’s important not to dismiss shortness of breath as a sign of aging or a lack of fitness; if you suddenly find it difficult to breathe, seek medical help immediately.
