Which condition may be caused by coronary artery disease, high blood pressure, and diabetes?

• A. Atrial fibrillation
• B. Sickle cell anemia
• C. Congestive heart failure
• D. Varicose veins

Answer: (C)

Chronic heart conditions like coronary artery disease, high blood pressure, and diabetes commonly lead to congestive heart failure because they damage the heart and increase its workload. CAD reduces oxygen supply to the heart muscle, weakening its pumping ability. High blood pressure forces the heart to work harder to push blood, causing the chambers to thicken and stiffen. Diabetes accelerates atherosclerosis and can impair heart muscle function and blood vessels. Over time, these effects combine to impair the heart’s pumping efficiency and its ability to manage fluid, leading to heart failure. In congestive heart failure, the body’s tissues don’t receive enough blood flow, and fluid can back up into the lungs or extremities, causing symptoms like shortness of breath and swelling.

Atrial fibrillation is an irregular heartbeat that can occur with heart disease, but it’s not the direct, defining outcome of these risk factors as consistently as heart failure is. Sickle cell anemia and varicose veins are not the typical consequences tied to this combination of conditions.
