Is Cardiovascular Science for Me?

Career Description

Cardiovascular science is the study of the function, structure, disorders and diseases of the vascular system, heart and blood. Job titles in cardiovascular science include perfusionist, invasive cardiovascular technologist, cardiologist and cardiovascular research scientist.

Invasive cardiovascular technologists serve as members of cardiac catheterization teams. You could assist physicians who perform angiograms or other cardiac catheterization procedures. Your duties may include monitoring vital signs, comforting the patient and charting health information. Perfusionists work as a member of a surgical team to operate heart and lung equipment. The equipment takes over the functions of heart and lungs by pumping and oxygenating the blood during surgical procedures. You could work with a physician to set up an external circulatory system for use in heart-related surgeries, such as organ transplant and chemotherapy.
