Which condition is marked by death or damage to heart muscle due to insufficient blood supply?

A heart attack, also known as myocardial infarction, is characterized by the death or damage to the heart muscle due to insufficient blood supply. This typically occurs when one or more coronary arteries become blocked, preventing adequate blood flow that carries oxygen to the heart tissue. Without this oxygen-rich blood, the heart muscle begins to die, which can result in permanent damage and can be life-threatening.

Understanding this condition highlights the importance of prompt medical intervention, which can restore blood flow and minimize heart muscle damage. Recognizing the symptoms of a heart attack, such as chest pain, shortness of breath, and radiating discomfort, is crucial for timely treatment and can significantly impact the outcome for the individual experiencing the event.
