Which test is commonly used to diagnose heart failure and assess its severity?

• A. Echocardiogram
• B. Skin Biopsy
• C. Liver Function Test
• D. Audiometry

Answer: (A)

Echocardiography provides both structural and functional information about the heart, which is essential for diagnosing heart failure and gauging its severity. This ultrasound test creates real-time images of the heart, showing chamber sizes, wall motion, and valve function. It also measures the ejection fraction, the percentage of blood the left ventricle pumps with each beat, which helps distinguish heart failure with reduced versus preserved ejection fraction and guides management. Doppler assessments estimate pressures inside the heart and pulmonary circulation, adding to the severity picture. Because it is noninvasive, widely available, and yields a comprehensive view of heart structure and function, it is the test most commonly used to diagnose heart failure and assess how severe it is. Skin biopsy isn’t related to heart function, liver function tests reflect liver injury or disease and aren’t used to diagnose heart failure or measure its severity, and audiometry tests hearing.
