Emory, Balloon Angioplasty, and the Musk Attack on Medical Diplomacy

By MIKE MAGEE

 “The recently announced limitation from the NIH on grants is an example that will significantly reduce essential funding for research at Emory.”       

                                              Gregory L. Fenes, President, Emory University 

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.

Why Texting Patients Works: The Health Belief Model

With the rise of cell phone usage, smart and otherwise, many health care providers, researchers and entrepreneurs alike have assumed that this ubiquitous technology can be used to improve health and wellbeing. Entrepreneurs have led the charge and so the common catch phrase “there’s an app for that” underscores the fact that nearly 17, 000 health related apps are available either for free or a small charge for Android or Apple users.  Young people in the US are perhaps the best targets of our mhealth efforts because they are eager users of mobile technology. However two questions arise naturally: 1) does data show that these apps lead to improved outcomes? 2) is there a theory of how we might use cell phones to improve health outcomes?

In a series of studies, we found that simply responding to text messages over a 3-month period led to improved quality of life and pulmonary function in pediatric asthma patients. In both studies, the researchers randomly assigned 30 asthmatic children, 10 to 17 years old, into three groups – a control group that did not receive any SMS messages; a group that received text messages on alternate days and a group that received texts every day. The children that received messages everyday between two scheduled appointments had the improved psychological and physical outcomes. Thus, our data does indicate that cell phones can be used effectively to improve health outcomes.

Perhaps more compelling is that we may have evidence of a possible mechanism that can lead to improved outcomes. The Health Belief Model is a cognitive theory of behavior change that espouses the notion that a critical pillar of behavior modification is that the individual must make the connection between the severity of the symptoms and the disease itself. In the case of asthmatic patients, we found that many times they attributed their symptoms to other causes. For example, they would say that they couldn’t exercise in the afternoon because they had a heavy lunch or that they couldn’t sleep the night before because they had seen a movie that had made them anxious— rather than attributing these symptoms (inability to exercise or sleep) to their asthma. The Health Belief Model also places value on acquiring knowledge about the disease. Thus, we sent patients texts messages that either asked about symptoms they had experienced or about asthma myths. Thus, our studies also indicate that improving symptom awareness and knowledge about their disease led them to have better medication adherence which in turn led to improved health outcomes.
