Heart Attack Causes And Symptoms

Heart Attack Causes And Symptom

A heart attack, also known as a myocardial infarction, occurs when the blood flow to a part of the heart muscle is blocked, usually due to the buildup of fatty deposits called plaque in the coronary arteries. Understanding the causes and recognizing the symptoms of a heart attack is crucial for prompt medical intervention. Here’s a comprehensive overview of the causes and symptoms:

Causes of a Heart Attack

Coronary Artery Disease (CAD): The most common cause of a heart attack is CAD, where the coronary arteries that supply blood to the heart become narrowed or blocked due to the accumulation of cholesterol and plaque. This restricts blood flow and can lead to a heart attack.

Plaque Rupture: Plaque buildup in the arteries can rupture or tear, leading to the formation of a blood clot. This clot can block the artery, cutting off blood supply to a portion of the heart muscle.

Spasm of Coronary Arteries: In some cases, the coronary arteries can experience spasms, causing them to narrow and reduce blood flow to the heart. This can result in a heart attack, even without significant plaque buildup.

Symptoms of a Heart Attack

Shortness of Breath: Difficulty breathing or sudden shortness of breath can occur, even without chest pain. It may be accompanied by a feeling of heaviness in the chest.

Chest Pain or Discomfort: The most prevalent symptom is a feeling of pressure, tightness, or pain in the chest that may radiate to the arms, neck, jaw, or back. The pain might be intense or intermittent.

Nausea and Vomiting: Some individuals experience nausea, vomiting, indigestion, or discomfort in the upper abdominal region during a heart attack.
