This is the most common symptom of a heart attack. Patients may feel pressure, tightness, or pain in the chest that lasts for more than a few minutes and is not easily relieved.
Heart attack patients may experience shortness of breath or difficulty breathing, especially during light physical activity.
A heart attack can cause nausea or vomiting, which may be related to discomfort caused by cardiac ischemia.
Patients may feel rapid or irregular heartbeats as the heart attempts to cope with ischemia.
A heart attack can sometimes lead to dizziness or fainting, which may be due to reduced cardiac output resulting in insufficient blood supply to the brain.
Sometimes, the pain from a heart attack can be mistaken for stomach pain or indigestion, especially when it is located in the upper abdomen.
Heart attack patients may feel extremely fatigued, even without engaging in any physical activity.
