Alfredo E. Rodríguez

Alfredo E. Rodríguez is an Argentine interventional cardiologist, clinical researcher, and author. He is the Chief of Interventional Cardiology Service at Otamendi Hospital and Director and Founder of the Cardiovascular Research Center (CECI) a non -profit Research Organization in Buenos Aires Argentina.
Rodríguez has conducted research in the field of cardiology with a particular focus on coronary angioplasty bypass surgeries, myocardial infarction, diabetes, and hemodynamics. He is the author of several books, including Coronary Transluminal Angioplasty and Controversies in Cardiology and has been the recipient of the Rafael Bullrich Award and the Geronimo H. Alvarez Prize.
Rodriguze is an Academic Editor of Academia Medicine Journal and the Editor in Chief of Argentina Journal of Cardiovascular Interventions.
Rodríguez received his medical degree from Córdoba National University, School of Medicine in 1974, and completed his residency in the Cardiology Department at Hospital Privado Sanatorio Güemes. He then completed his PhD in Coronary Angioplasty and Intracoronary Thrombolysis from Córdoba Catholic University. Following his PhD, he focused on Hemodynamics and Angiography and received an MD from the Argentine Collegium of Hemodynamics.
In 1981, Rodriguez had training in coronary angioplasty for a short period of 3 months at the San Francisco Heart Institute led by Richard K Myler. Rodríguez is the former assistant director and Chief of Interventional Cardiology Service at Hospital Privado Sanatorio Güemes and Interventional Cardiology Service at Sanatorio Anchorena. He also held an appointment as the Director of Post Graduate Medical School at the Buenos Aires University School of Medicine at the Sanatorio Otamendi Unit. Additionally, he founded and currently serves as the Director of the Cardiovascular Research Center (CECI) in Buenos Aires, a non-profit Clinical Research Organization and is the Chief of the Interventional Cardiology Service at Otamnedi Hospital in Buenos Aires and in Sanatorio Las Lomas in San Isidro.
Rodríguez is known for his clinical research in the area of cardiology, with an interest in interventional cardiology including coronary restenosis as well as myocardial infarction and diabetes. He has published several manuscripts.
Throughout his research career, Rodríguez has worked on comprehending the efficacy of percutaneous coronary interventions in patients with multivessel disease by comparing it with the coronary artery bypass technique. Additionally, he reported that transluminal coronary angioplasty treatment had no significant in-hospital complications but a lower efficacy rate when compared to coronary artery bypass in patients with multiple vessel disease, called ERACI I and II trials He conducted multiple randomized clinical trials between 1993 and 2005, including those in 1993, 1995, 1997, 2001, and 2005, to elucidate the aftereffects of interventional treatments among cardiac patients. He was the first to describe the role of acute wall recoil in the pathophysiology of coronary balloon angioplasty and the prevention of this phenomenon with bare metal stent implantation.
During his work on myocardial infarction, Rodríguez evaluated the efficacy of several angioplasty approaches, including tirofiban and abciximab infusion, as well as the implantation of both Sirolimus-Eluting and uncoated stents. In 1998, he published the first randomized trial comparing balloon angioplasty with stents in acute myocardial infarction, known as the GRAMI trial, in the American Journal of Cardiology. He suggested the use of rheolytic thrombectomy prior to stenting of the infarct artery in patients suffering from acute myocardial infarction and exhibiting evidence of coronary thrombus. Additionally, he presented the consideration of Abciximab plus IRA as the routine reperfusion strategy in patients with percutaneous mechanical revascularization. During the early 2000s, he examined the problem of DES (drug-eluting stents) late stent thrombosis, and reported on a trial related to this issue in 2006 in the Journal of the American College of Cardiology, as well as in European Heart Journal and Euro Intervention in 2007. In 2006, he also conducted a randomized trial that demonstrated the benefits of using oral immunosuppressive drugs to prevent restenosis following bare metal stent implantation. Later in 2023, he conducted research on the issue of non-cardiac death and cancer, and proposed the limited use of drug-eluting stent transplantation according to patient's age, lesion complexity, and life expectancy.
In his book, Controversies in Cardiology, Rodríguez has discussed topics that are characterized by ambiguity, ongoing discussions, or a lack of agreement according to existing guidelines. He has highlighted three main areas i.e., cardiovascular risks, its diagnosis, and management. Jorge Lerman commended this book for its ability to explore controversial topics that have not been widely discussed and provide a comprehensive analysis of each subject. He further added that "This innovative format constitutes an attractive incentive for the reader who is interested in learning about the advances in cardiovascular science."
In addition to his work comparing angioplasty approaches and coronary artery bypass, as an interventional cardiologist, Rodríguez has also studied the impact of diabetes on the mortality and efficacy of heart surgeries among diabetic patients. He proposed that using a coronary PC coated stent during the percutaneous intervention in diabetic patients with small coronary arteries has the ability to provide improved angiographic outcomes. Additionally, he noted that the use of paclitaxel-eluting balloons followed by bare-metal stents in treating diabetic patients showed a notably favorable result compared to treating them with a single bare-metal stent. His research further elucidated that a coronary artery bypass graft is a better option than percutaneous coronary intervention as it decreases the risk of mortality and other major cardiovascular issues in nondiabetic patients.
