Cardiac nurses, also known as cardiovascular nurses, are trained advanced practice nurses (APRNs) who work alongside cardiologists and other healthcare providers to offer comprehensive cardiovascular care to patients with acute and chronic heart conditions. Cardiac nurses have intensive skills and expertise in diagnosing, treating, and managing illnesses that affect the body's complex circulatory system. They strive to help clients achieve optimal cardiovascular health through preventative measures such as health counselling, screening, and stress tests, as well as disease prevention and management tactics. They also treat patients with coronary artery disease, including those who have undergone bypass surgery or have had a heart transplant. Although cardiac nurses were traditionally employed in hospital cardiology units, cardiovascular interventional units, and cardiothoracic surgery units, there is an increasing demand for cardiac nurses in diagnostic, rehabilitative, and long-term care settings. Cardiac nurses also play a significant role in a variety of cardiology-related medical settings.
