Which specialist focuses on heart conditions and diseases?

• A. Neurologist
• B. Cardiologist
• C. Oncologist
• D. ER Doctor

Answer: (B)

A heart specialist is a cardiologist. Cardiology is the field that studies and treats diseases of the heart and blood vessels. A cardiologist diagnoses and manages conditions such as coronary artery disease, heart rhythm problems, heart failure, and valve issues. They use tests like ECGs, echocardiograms, and stress tests to assess how the heart is functioning and decide on treatments, which can include medications, lifestyle changes, or procedures such as angioplasty or pacemaker therapy when needed. Other listed roles focus on different areas: a neurologist treats the brain and nerves, an oncologist treats cancer, and an ER doctor handles acute emergencies across many body systems rather than specializing in heart diseases.
