John F Canales, MD, FACC
Growing up listening to his father, an insurance agent, tell the stories of his clients had a profound effect on the kind of physician Dr. John Canales would become. “I like hearing my patients’ stories. I think it makes me a better interventionalist because I understand where they’re coming from and how my treatments may affect their lives,” says Dr. Canales.
Dr. Canales was trained at some of the country’s most prestigious institutions. He completed medical school at Washington University in St. Louis and his internship and residency at the University of Texas Southwestern in Dallas. Dr. Canales then went to the Texas Heart Institute in Houston for his general and interventional cardiology fellowships. While there, he completed training in the non-surgical treatment of complex coronary and peripheral vascular disease.
Dr. Canales was also very active academically at the Texas Heart Institute. He investigated the role of using a patient’s own stem cells to regenerate damaged heart muscle and to rebuild arteries in the legs with severe blockages. His academic excellence, interventional skill, and compassionate care resulted in the honor of being named Chief General Cardiology Fellow and Chief Interventional Fellow at the Texas Heart Institute.
After training, Dr. Canales spent two years in New Braunfels practicing general and interventional cardiology. During his short time there, he became the Director of the Catheterization Laboratory at Christus Santa Rosa Hospital in New Braunfels and Chairman of the Limb Salvage Committee, a group dedicated to caring for patients with severe peripheral arterial disease.
But San Antonio was his home growing up and many of his family and friends were still there. So, Dr. Canales decided to join the Cardiology Clinic of San Antonio in August, 2013.
His interests and skills include treating complex coronary interventions and peripheral vascular disease. He has taken a special interest in patients with critical limb ischemia, renal arterial disease, lower extremity arterial disease, and venous disease. Dr. Canales is specially trained to use drug-eluting stents and balloons, cutting-edge atherectomy devices, and fractional flow reserve and intravascular ultrasound to guide coronary and peripheral interventions. He also performs transradial cardiac catheterizations—accessing the heart via the radial artery in the wrist instead of the femoral artery in the groin.
Dr. Canales is board certified in interventional cardiology, cardiovascular disease and nuclear cardiology. He practices out of Cardiology Clinic’s Northeast office, Stone Oak and Uvalde offices.
