How long does a heart attack last?

Heart attacks generally last between one and 12 hours. The length of time it takes for a heart attack to occur varies depending on the area of the heart that is affected. If the attack involves the coronary artery that supplies the upper part of the heart, it usually takes just a few minutes.

If it involves the coronary artery that supplies the lower part of the heart, the process can take up to an hour. Heart attacks last on average between one and four hours. The amount of time a person is actually experiencing chest pain depends on several factors, including how far the affected coronary artery is from the heart, and the severity of the damage.

The more severely blocked or damaged the artery, the longer it takes for the heart to get enough oxygen-rich blood to feed the heart muscle. Heart attacks that occur very quickly, which is often the case with those that occur in people with heart disease, typically last less Heart attacks last for 30 minutes to four hours.

Heart attack symptoms usually occur within the first hour of the onset of chest discomfort. However, it can sometimes take an hour or more for the symptoms to occur. On very rare occasions, symptoms may appear and disappear within minutes.

Heart attacks that are not too severe can last under one hour and do not cause permanent damage. Heart attacks that last longer are more serious and may cause permanent damage. They may also trigger the formation of scar tissue in the coronary arteries, which narrows them and limits the amount of oxygen-rich blood that flows to the heart.
