What can ischemia to the heart potentially cause?

• A. Coronary artery disease
• B. Angina and infarction
• C. Heart murmur
• D. Atrial septal defect

Answer: (B)

Ischemia refers to a reduced blood flow to the heart muscle, which can result in a lack of adequate oxygen and nutrient supply. This condition can lead to angina, which is chest pain or discomfort resulting from the heart muscle not receiving enough blood. Angina can manifest as stable, unstable, or variant types, depending on the nature of the ischemia. Additionally, prolonged ischemia can lead to myocardial infarction, commonly known as a heart attack. This occurs when the blood flow is so severely restricted that it causes permanent damage to the heart muscle. Therefore, the consequences of ischemia, which include both angina and the risk of infarction, highlight its serious impact on heart health. In contrast, the other options relate to different cardiovascular issues that are not directly consequences of ischemia. Coronary artery disease, although it can lead to ischemia, is a chronic condition caused by the buildup of plaques in the coronary arteries and does not directly answer the potential consequences of ischemia itself. A heart murmur is typically related to abnormal heart valve function rather than ischemia. An atrial septal defect is a congenital heart defect that involves an opening in the wall between the heart’s upper chambers, and while it can affect blood flow,
