How long does a heartattack usually last?

Answer 1

There was an article recently that said the duration of unusual or severe compliants for supposedly sudden death from heart attacks, showed the victims had symptoms for from 2 to 10 hours prior to "leaving the rest of us behind".

This was from interviews from family members or other witnesses who were interviewed for this specific study.

Most did not think they were having a heart attack. First heart attacks are typically fatal in about 60% (6 of 10) instances.

For those of us who are heart patients, a spray of nitroglycerin or a tablet may relieve symptoms in a few minutes. Without it, it depends on if you have collateral arteries that will open, calming down, or getting to an Emergency Room, or summoning help from 911. The pain will last until the blockage is relieved, but may stop when the heart tissue lacking oxygen dies. I don't know about that yet.

The intense chest pain is the classic symptom, but not the only one. The pain can be mild for a blockage in a tiny artery supplying less than 1% of the heart, or big for a total blockage of a main artery supplying 40% of the heart. Smaller blockage pains can actually be felt across the heart in the vicinity of where they occur.

Answer 2

Practically speaking the heart attack can occur during the sleep and the patient won't notice it, it's accidentally discovered on routine EKG/ Annual check up.
In old Diabetics there may be no symptom, sudden death.
It is generally known that 1st 24 Hours are critical during and than the enzymes/EKG will show weather the patient has settled still he has to remain on ACS protocol.
It varies so any one giving a specific time table is incorrect much depend on the extent of coronary artery status and underlying disease if any.

Answer 3

A heart attack can potentially go on for several hours. Many people let the symptoms linger, thinking they will go away, before calling for help. I have even had people complaining of chest pain for a matter of days before calling. The sooner medical intervention is started, however, the more likely there will be a successful outcome. The longer the pain is ignored, the more damage is done to the heart.

Answer 4

A heart attack will last until whatever caused the heart attack has been taken care of. In my case it was about an hour because I got to the emergency room very quickly and they immediately took me in and put in stents.

Answer 5

it can be for seconds, hours, days...it depends
