What common condition can lead to an enlarged heart due to high blood pressure?

An enlarged heart, medically known as cardiomegaly, can occur as a direct result of high blood pressure, a condition that causes the heart to work harder to pump blood. Over time, this increased workload can lead to changes in the heart's structure, particularly the left ventricle, causing it to thicken and enlarge. While the other conditions listed may be associated with heart problems or contribute to an enlarged heart, the term "enlarged heart" directly refers to the condition resulting from these stresses on the heart, such as those caused by hypertension. Thus, identifying the enlarged heart as a consequence of high blood pressure captures the essence of how chronic high blood pressure affects cardiac dimensions and functions.
