What condition do blood clots in the heart commonly cause?

• A. A stroke.
• B. A ruptured appendix.
• C. High blood sugar.
• D. A heart attack.

Answer: (D)

When a blood clot blocks a coronary artery, the heart muscle behind the blockage loses oxygen and becomes damaged. This interruption of blood flow is what triggers a heart attack (myocardial infarction). The heart needs a constant supply of blood to work; if a clot stops that flow, the affected area of the heart cannot function properly and tissue may die, leading to chest pain, shortness of breath, and other symptoms. While a clot can travel elsewhere and potentially cause a stroke, the direct and common consequence of a clot within the heart’s own circulation is a heart attack.
