Heart Attack

Heart Attack

What is Heart Attack ?

A heart attack, also known as a myocardial infarction, occurs when the flow of blood to a part of the heart is blocked, usually by a blood clot. This blockage prevents oxygen from reaching the heart muscle, causing damage or death to the affected tissue.

what is coronary artery ?

The coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle. There are two main coronary arteries: the left coronary artery and the right coronary artery, each branching into smaller arteries to cover the heart’s surface.

How Coronary Arteries Get Blocked ?

1. Plaque Buildup (Atherosclerosis): Over time, cholesterol and other substances in the blood form plaque, which sticks to the inner walls of the arteries. This process is known as atherosclerosis.

2. Plaque Rupture: If a plaque ruptures, it can cause a blood clot to form. This clot can partially or completely block the artery.

3. Reduced Blood Flow: The buildup of plaque narrows the arteries, reducing blood flow to the heart muscle. This can lead to chest pain (angina) or, if the artery is completely blocked, a heart attack.

what happens if your coronary artery gets blocked ?

When a coronary artery gets blocked, it can have serious consequences for your heart and overall health. Here’s what happens:

Immediate Effects-
  1. Reduced Blood Flow: The blockage prevents oxygen-rich blood from reaching parts of the heart muscle. This can cause chest pain (angina) and shortness of breath.

  2. Heart Attack: If the blockage is complete, it can lead to a heart attack (myocardial infarction). This occurs because the heart muscle is deprived of oxygen, causing damage or death to the affected tissue.

Symptoms of a Heart Attack-
Long-Term Effects-
  1. Heart Failure: If a significant portion of the heart muscle is damaged, the heart may not pump blood effectively, leading to heart failure.

  2. Arrhythmias: Damage to the heart muscle can disrupt the heart’s electrical signals, causing irregular heartbeats (arrhythmias).
