About

St. John has served northeastern Oklahoma in comprehensive cardiovascular care for decades.

We pioneered many cardiovascular treatments, including the first pacemaker implant, first bypass surgery and first angioplasty in Tulsa.  Now, thousands of patients turn to us each year for the latest cardiac technologies, including all-digital cardiovascular imaging and a cardiac-dedicated 64-slice CT scanner.

With St. John Heart Institute, your heart’s in the right place. 

St. John is a part of Ascension, the nation's largest Catholic and nonprofit health system. Together, we are dedicated to providing compassionate, personalized care in our community. To learn more about Ascension, click HERE
