25 Which of the following is a key characteristic of hypertrophic cardiomyopathy?
A Dilation of the ventricles B Thickening of the ventricular walls C Decreased contractility D Regurgitation of heart valves Explanation: Hypertrophic cardiomyopathy is characterized by abnormal thickening of the ventricular walls, which can lead to obstruction.
26 What is the primary purpose of an echocardiogram in a patient with suspected
heart failure?
A To assess coronary artery blockages B To evaluate cardiac structure and function C To measure blood pressure D To monitor heart rate Explanation: An echocardiogram evaluates the structure and function of the heart, which is crucial in diagnosing heart failure.
27 A patient with known coronary artery disease is scheduled for a coronary
angiogram. What is the primary goal of this procedure?
A To measure cardiac output B To visualize the coronary arteries C To assess valve function

shows ST-segment elevation in leads II, III, and aVF. What is the most likely
diagnosis?
