6. Nausea or vomiting
Nausea and vomiting can occur during a heart attack due to the body’s stress response and reduced blood flow affecting the digestive system. These symptoms sometimes lead people to mistake the event for food poisoning or a stomach virus, delaying treatment.
Heart attack-related nausea often happens with other symptoms such as chest pain, sweating, or lightheadedness. It is more common in women and older adults.
7. Lightheadedness or dizziness
Feeling dizzy or lightheaded during a heart attack results from decreased cardiac output and subsequent low blood pressure. This can impair blood flow to the brain, causing faintness or near-fainting episodes.
This symptom requires urgent medical attention, especially if it occurs alongside chest pain, shortness of breath, or palpitations.
8. Fatigue
Unexplained fatigue or weakness is a subtle but important heart attack symptom, particularly in women. The heart’s impaired function reduces oxygen delivery to muscles and organs, causing unusual tiredness that may start days before the event.
This fatigue is different from normal tiredness and is often described as overwhelming or persistent, not relieved by rest.
