Cardiac nursing specializes in preventing and treating heart conditions. These nurses operate in both inpatient and outpatient settings, assisting medical and surgical patients through acute illness or chronic disease management. Addressing the leading cause of death in the United States, cardiovascular nurses care for, treat, and rehabilitate individuals with heart disease. Since everyone has a heart, the potential for cardiovascular complications exists in all patients. Cardiovascular nursing is an integral aspect of overall nursing care. Nurses educate patients about their condition and necessary lifestyle adjustments for recovery and long-term wellness. Serving as a central point of contact, they provide assessments and updates to doctors, patients, and families during extended hospital stays.
