Healing the Heart: Groundbreaking Advances

(DGIwire) – The past several decades have witnessed a series of remarkable breakthroughs in the area of heart care. Here are six advances that have propelled the state of coronary medicine and given heart patients a new lease on life.

  • 1958: Coronary Angiography. F. Mason Sones Jr. accidentally injected a large amount of dye into the small vessels of a patient’s heart during a routine imaging test, reports WIRED magazine; the result was the birth of modern cardiac imaging.
  • 1967: Bypass Surgery. Rene Favaloro stopped a patient’s heart, took a section of vein from the patient’s leg and sewed one end to his aorta and the other beyond the blockage. According to the Cleveland Clinic, this was the first saphenous vein coronary artery bypass graft.
  • 1977: Balloon Angioplasty. This technique—used to widen coronary arteries narrowed by plaque—was first performed by Dr. Andreas Gruentzig, building on the work of physician Charles Dotter, notes the Emory School of Medicine.
  • 1993: Bare Metal Stents. Used for a variety of indications including angina and acute myocardial infarction, the first model of bare metal stents was designed by radiologist Cesar Gianturco and interventional cardiologist Gary Roubin, reports Medscape.
  • 2003: Drug Eluting Stents. These are metal stents coated with a drug that suppresses the reblocking or closing up of an artery after angioplasty; their approval was influenced by a study comparing their use to plain metal stents.
  • 2017: Microvascular Gene Therapy: One of the most recent and exciting steps forward involves the use of genetic therapy to boost the heart’s ability to grow new arteries, which could help many patients avoid chest pain or prevent heart attacks.

The steady pace of innovation in heart care has truly opened new possibilities for treating patients in an effective manner. Nobody can say where the path of discovery in heart science will lead us tomorrow—but we are justified in being excited by the cutting-edge of the field as it stands today.
