In 1900, the U.S. life expectancy was 47 years. Between maternal deaths in child birth and infectious disease, it is no wonder that cardiovascular disease (barely understood at the time) was an afterthought. But by 1930, as life expectancy approached 60 years, Americans stood up and took notice. They were dropping dead on softball fields of heart attacks. 

Remarkably, despite scientific advances, nearly 1 million Americans ( 931,578) died of heart disease in 2024. That is 28% of the 3,279,857 deaths last year. 

The main cause of a heart attack, as every high school student knows today, is blockage of one or more of the three main coronary arteries – each 5 to 10 centimeters long and four millimeters wide. But at the turn of the century, experts didn’t have a clue. When James Herrick first suggested blockage of the coronaries as a cause of heart seizures in 1912, the suggestion was met with disbelief. Seven years later, in 1919, the clinical findings for “myocardial infarction” were associated with ECG abnormalities for the first time. 

Scientists for some time had been aware of the anatomy of the human heart, but it wasn’t until 1929 that they actually were able to see it in action. That was when a 24-year old German medical intern in training named Werner Forssmann came up with the idea of threading a ureteral catheter through a vein in the arm into his heart. 

His superiors refused permission for the experiment. But with junior accomplices, including an enamored nurse, and a radiologist in training, he secretly catheterized his own heart and injected dye revealing for the first time a live 4-chamber heart. Two decades would pass before Werner Forssmann’s “reckless action” was rewarded with the 1956 Nobel Prize in Medicine. But another two years would pass before the dynamic Mason Sones, Cleveland Clinic’s director of cardiovascular disease, successfully (if inadvertently) imaged the coronary arteries themselves without inducing a heart attack in his 26-year old patient with rheumatic heart disease. 

But it was the American head of all Allied Forces in World War II, turned President of the United States, Dwight D.Eisenhower, who arguably had the greatest impact on the world focus on this “public enemy #1.” His seven heart attacks, in full public view, have been credited with increasing public awareness of the condition which finally claimed his life in1969. 

Cardiac catheterization soon became a relatively standard affair. Not surprisingly, less than a decade later, on September 16, 1977, an East German physician, Andreas Gruntzig performed the first ballon angioplasty, but not without a bit of drama. 

Dr. Gruntzig had moved to Zurich, Switzerland in pursuit of this new, non-invasive technique for opening blocked arteries. But first, he had to manufacture his own catheters. He tested them out on dogs in 1976, and excitedly shared his positive results in November that year at the 49th Scientific Session of the American Heart Association in Miami Beach. 

He returned to Zurich that year expecting swift approval to perform the procedure on a human candidate. But a year later, the Switzerland Board had still not given him a green light to use his newly improved double lumen catheter. Instead he had been invited by Dr. Richard Myler at the San Francisco Heart Institute to perform the first ever balloon coronary artery angioplasty on an awake patient.

Gruntzig arrived in May, 1977, with equipment in hand. He was able to successfully dilate the arteries of several anesthetized patients who were undergoing open heart coronary bypass surgery. But sadly, after two weeks on hold there, no appropriate candidates had emerged for a minimally invasive balloon angioplasty in a non-anesthetized heart attack patient. 

In the meantime, a 38-year-old insurance salesman, Adolf Bachmann, with severe coronary artery stenosis, angina, and ECG changes had surfaced in Zurich. With verbal assurances that he might proceed, Gruntzig returned again to Zurich. The landmark procedure at Zurich University Hospital went off without a hitch, and the rest is history.
