Which medical specialist focuses on diseases and disorders of the heart and blood vessels?

• A. Cardiologist
• B. Endocrinologist
• C. Orthopedic
• D. Neurologist

Answer: (A)

Understanding this question starts with knowing how medical specialties map to body systems. The heart and blood vessels form the cardiovascular system, and the doctor who specializes in diseases and disorders of this system is the cardiologist. A cardiologist is trained to diagnose and manage conditions like coronary artery disease, heart failure, heart rhythm problems, valve issues, and hypertension. They also interpret tests such as EKGs, echocardiograms, stress tests, and cardiac catheterization to assess heart health and guide treatment.

In contrast, endocrinology deals with hormones and metabolism, orthopedics with bones and joints, and neurology with the brain and nervous system. So for heart and vascular problems, the appropriate specialist is the cardiologist.
