Welcome to The Heart Smart Group

Marc D. Krock, M.D.

Our Mission

I founded The Heart Smart Group to provide personalized, high quality, patient-centered cardiovascular care dedicated to the specific needs of each patient. Using state-of-the art technology, we focus on timely techniques and patient education to minimize the risk of heart attack and stroke and to prevent, treat, and manage cardiovascular disease.

As you’ll read below, we’re excited to continue to fulfill our objective to provide the highest quality patient care with the dedication of a new cardiac catheterization lab at Medical City Frisco and the addition of a new extremely qualified physicians with multiple cardio-related board certifications.

New Cardiac Catheterization Lab Added to Medical City Frisco

In keeping with the plans HCA announced at the time of its acquisition to expand the services and technology provided at the Frisco facility, a new state-of-the-art heart catheterization lab was added and dedicated on February 14, 2017. 

​The cath lab is a dedicated room equipped with highly specialized diagnostic imaging equipment that allows interventional cardiologists to diagnose and treat coronary artery disease through guiding catheters or devices into the heart’s chambers or arteries. It allows the cardiologist to visualize the heart and treat a variety of abnormalities quickly. Heart procedures performed in a cath lab are often less invasive with a shorter recovery period. 

​The cath lab will now allow emergency crews to bring heart attack patients directly to Medical City Frisco for immediate treatment. ​

​Dr. Krock is proud to have been selected to be medical director of the new lab.
