Cardiology Center of Southern Indiana

Clark Memorial Heart Center

Heart disease is the number one killer in America, claiming more victims every year than the top seven cancers combined.

At the Cardiology Center of Southern Indiana, our focus is the diagnosis, treatment and rehabilitation of patients with coronary artery disease, heart failure, valvular heart disease and abnormal heart rhythms. We also work at Clark Memorial Hospital’s state-of-the-art Heart Center, providing world-class heart care to the people of southern Indiana.

At the Clark Memorial Heart Center, we provide cardiovascular diagnostics and stabilization along with interventional cardiac services like catheterization and angioplasty. We have two cardiac catheterization laboratories for balloon angioplasty procedures and twelve private telemetry rooms for patients to stay overnight after their procedure.

And to make it easier for patients and their families, procedure preparations, cardiac procedures and post-procedure recovery occurs in one convenient place.
