Signs and Symptoms of Heart Attack

Chest pain or pressure is a common symptom of heart attack. Cardiac chest pain is often vague, or dull, and may be described as a pressure or band-like sensation, squeezing, heaviness, or other discomfort. Heart attacks frequently occur from 4:00 a.m. to 10:00 a.m.due to higher adrenaline (a hormone that prepares the body for fight or flight) levels released by the adrenal glands during the morning hours. Interestingly, heart attacks do not usually happen during exercise, although exercise is commonly associated with angina (heart pain). Approximately 1/4th of all heart attacks are silent i.e. without associated chest pain. In diabetics, the incidence of “silent” heart attacks may be much higher.
