Myocardial infarction commonly known as?

• A. A heart attack.
• B. A stroke.
• C. An arrhythmia.
• D. Heart failure.

Answer: (A)

Myocardial infarction is most commonly called a heart attack. This happens when a coronary artery is blocked, cutting off blood supply to a portion of the heart muscle, leading to ischemia and eventual death of heart tissue. The term “heart attack” reflects the sudden injury to the heart from interrupted blood flow. In contrast, a stroke affects the brain, an arrhythmia is an abnormal heart rhythm, and heart failure refers to the heart’s reduced ability to pump effectively; these are distinct conditions with different causes and treatments.
