Cardiovascular nurses take care of people with heart disease and interact with their patients’ families. They keep monitoring and treating acutely ill patients. They also focus on cardiac rehabilitation. Rehabilitation is the way of helping patients to make a change in lifestyle in order to prevent the worsening of their disease. Most of the cardiovascular clinical nurse specialists (CNSs) work in hospitals. They take care of the critically ill patients and those recovering from cardiac treatments such as bypass, angioplasty or pacemaker surgery. Cardiovascular nurses may also work at patient’s home to help them recover. Critical care/ Intensive care nurses also work with children and adults of all ages, although heart disease generally affects older people. They may also work as part of a team under the direction of a cardiologist.
