Cardiovascular nurses are who cares for people with heart problems. Cardiac nurses require more than just a technical understanding of the human body. They require specialised training in the heart and how it functions, making this a very demanding profession. Patients with a variety of heart diseases or conditions are treated and cared for by cardiovascular nursing practitioner. Patients with coronary artery disease or congestive heart failure, as well as those recovering after angioplasty or sidestep surgery, may fall under this category.
