Our board-certified interventional Cardiologist Tampa performs a variety of interventional cardiology treatments, including cardiac catheterization and stenting, as well as peripheral angiograms and stenting. Coronary artery disease is a condition caused by the build-up of a waxy material called plaque within the coronary arteries. These arteries provide your heart muscle with oxygen-rich blood. Coronary atherosclerosis occurs when plaque accumulates in these arteries. When substantial atherosclerosis develops in the arteries, it might manifest as chest pain (angina), shortness of breath, or other symptoms indicative of significant obstruction. These symptoms may suggest the impending onset of a heart attack.
