What Is the leading cause of death in the first hours after a heart attack?

The leading cause of death in the first hours after a heart attack is often attributed to ventricular fibrillation or other lethal arrhythmias. These irregular heartbeats can occur due to the heart's electrical instability following the loss of blood flow and oxygen. Additionally, complications such as cardiogenic shock or severe heart failure may arise, further increasing the risk of mortality during this critical period. Prompt medical intervention is essential to restore normal heart rhythm and function.
