A heart attack happens when there’s a blockage in a coronary artery that cuts off blood supply to the heart. An artery can be blocked by fatty deposits that form plaques or blood clots, or cause spasms that block blood flow. Typically, a combination of factors leads to a heart attack, not just one. It can take years for arteries to become dangerously clogged. When something suddenly triggers a cardiovascular event, it can seem like it came out of nowhere when it was actually years in the making.
Feelings of intense anger can trigger physiological changes that raise the risk of a heart attack. A rush of stress hormones speeds up the heart rate and raises blood pressure. Those hormones also encourage the formation of blood clots. The result is an elevated risk of a dangerous cardiovascular event for about two hours after a person experiences a high level of anger. Any stressful event can have a similar effect on the heart.
