Cardiac nursing is a specialisation that focuses on preventing and treating heart diseases. Cardiac nurses work in both inpatient and outpatient settings, caring for medical and surgical patients and guiding them through acute sickness or chronic disease management. Cardiovascular nurses care for, treat, and rehabilitate patients with heart disease, which is the leading cause of death in the United States. Because all of our patients have hearts, they all have the potential to develop complications such as cardiovascular disorders. Cardiovascular nursing is woven throughout every element of nursing. Cardiovascular nurses inform patients about their illness and the lifestyle modifications that are necessary for rehabilitation and long-term health. During a protracted hospital stay, they might act as a point person, offering assessments and updates to physicians, patients, and families.
