While both cardiologists and cardiac surgeons focus on heart-related conditions, their roles and areas of expertise differ. Cardiologists primarily diagnose and manage heart diseases through non-invasive procedures and medications. They perform tests, interpret results, prescribe treatments, and provide long-term care for heart conditions. On the other hand, cardiac surgeons specialize in performing surgical procedures on the heart and blood vessels. They are trained in complex surgeries like coronary artery bypass grafting, valve replacement, and heart transplantations. Cardiologists and cardiac surgeons often work together as part of a multidisciplinary team to provide comprehensive care to patients.
