In the world of modern cardiology, there are pioneers of procedure and architects of systems. Dr. Samer Y. Kazziha is a rare master of both. As a top interventional cardiologist and the leader of one of Michigan’s largest heart and vascular institutes, he operates with equal fluency in the microscopic world of a coronary artery and the complex ecosystem of a multi-hospital network. His life’s work is a testament to the idea that to truly heal a community, you must mend more than just the heart.
The landscape of a human heart, viewed through the lens of an angiogram, is a delicate and vital geography. It is a world of intricate pathways, of life-giving flow and potentially catastrophic blockages. Dr. Samer Y. Kazziha has spent decades navigating this terrain with the skill of a master cartographer and the precision of a bomb disposal expert. With a string of fellowships from institutions like the Cleveland Clinic Foundation and multiple board certifications in Internal Medicine, Cardiovascular Diseases, Interventional Cardiology, and Endovascular Medicine, he is one of the most credentialed and respected cardiologists in the country.
But to define Dr. Sam solely by his procedural skill is to miss the larger picture. His career has been a parallel journey: one path leading to the mastery of the catheter and the stent, the other leading to the mastery of the hospital department and the healthcare system. He has moved seamlessly from the role of clinician to that of leader, from Program Director of an interventional cardiology fellowship to Chief of Cardiovascular Services at major hospitals, and now, to his current position as the Chief Medical Director at McLaren Heart & Vascular Institute.
To understand his impact is to understand that he sees the patient on the table not just as an individual case, but as a data point in a much larger system of care. How was this patient educated about their risks? How quickly did they get from the emergency room to the cath lab? What is the hospital’s protocol for managing their recovery? For Dr. Sam, these are the fundamental components of a system that can be optimized, streamlined, and ultimately, made more effective at saving lives. He is not just treating a disease; he is re-engineering the entire process of care.
The Foundation of a Polymath
Dr. Sam’s journey is one of relentless intellectual acquisition. It’s a story told in a succession of prestigious fellowships, each one adding another layer of specialization. After earning his M.D. from the University of Damascus, his post-graduate training in the United States became a grand tour of cardiovascular medicine. He pursued fellowships in Critical Care Medicine , Cardiovascular Preventive Medicine , Clinical Cardiology , Interventional Cardiology , and Vascular Medicine. It was a deliberate and comprehensive education that transformed him into a medical polymath, capable of understanding a patient’s condition from every conceivable angle.
This deep and varied training gave him a unique perspective. He wasn’t just an interventionist focused on the procedure; he was a vascular medicine expert, a preventive medicine advocate, and an internal medicine physician. This holistic view became the foundation of his career. It allowed him to see the connections that others might miss and to build programs that addressed the full continuum of cardiovascular care.
His early career saw him quickly ascending into leadership roles. He was Co-Director of the Cardiac Catheterization Lab at St. John Hospital and Medical Center and later became the Medical Director of the entire Cardiac and Vascular Intervention Program at Mount Clemens Regional Medical Center. It was here that he began to hone his skills as a system builder, developing protocols, directing research, and establishing one of the region’s premier cardiovascular programs. His work was instrumental in the hospital being named one of the nation’s 100 Top Cardiovascular Hospitals by Solucient in both 2003 and 2005.
The Innovator and the Investigator
Parallel to his rise as a clinical leader, Dr. Sam has been a prolific and influential researcher. He has served as the primary investigator for over 30 clinical trials, placing him at the forefront of cardiovascular innovation. His name is attached to studies that have shaped the modern practice of interventional cardiology, from evaluating new generations of drug-eluting stents like the Orsiro to pioneering studies in carotid stenting and heart failure management.
His research portfolio reads like a history of the last two decades of cardiovascular advancement. He was an investigator on the TITAN-TIMI 34 trial, which explored the early initiation of anti-platelet therapy in heart attack patients, and the ADVANCE MI trial, which studied facilitated angioplasty. He has delved into the world of intravascular ultrasound, investigating plaque characterization in the global VH-IVUS Registry and exploring the link between lipid-rich plaques and future coronary events in the LRP-Infraredx study.
This deep involvement in research is not an academic exercise for Dr. Sam. It is a fundamental part of his commitment to providing the best possible care. By participating in these trials, he has been able to bring cutting-edge technologies and therapies to his patients in Michigan long before they become the standard of care. It is a direct translation of innovation from the research bench to the patient bedside.
The Architect of Regional Systems
In recent years, Dr. Sam has taken on roles that have allowed him to apply his expertise on a massive scale. As the Chief of Cardiovascular Services at Henry Ford Macomb Hospital from 2018 to 2022 and the Executive Director of Cardiovascular Services at Ascension Crittenton Hospital from 2007 to 2018, he was responsible for the strategic direction and clinical quality of the entire service lines.
In these roles, he was not just a manager; he was an architect. He established an Interventional Cardiology Fellowship program at Ascension Crittenton, mentoring the next generation of physicians. He served as the senior leader sponsor for initiatives aimed at achieving Blue Cross Blue Shield’s “Blue Distinction” for cardiac care and improving heart failure outcomes through the American College of Cardiology’s “Hospital to Home” initiative.
Now, as the Chief Medical Director of the McLaren Heart & Vascular Institute, he oversees one of the largest and most comprehensive cardiovascular programs in the state. It is a role that leverages every aspect of his extensive experience—his clinical acumen, his research background, and his proven leadership. He is tasked with standardizing care, driving innovation, and ensuring clinical excellence across a network of hospitals. It is the culmination of a career spent building, refining, and leading.
The Teacher in the Community
Despite the immense responsibilities of his leadership roles, Dr. Sam has never lost sight of the importance of education, both for his fellow physicians and for the public. He is a Clinical Associate Professor at Wayne State University School of Medicine, a role in which he has been recognized with a Physician Teaching Recognition Award for his commitment to mentoring students and residents.
However, his classroom extends far beyond the university. Dr. Sam is a fixture in the community, a tireless advocate for public health education. A glance at his career reveals a staggering list of community outreach activities. He has delivered dozens of lectures at senior centers, community health fairs, and corporate wellness events. He speaks on topics ranging from “Preventing Heart Disease” and “Stroke Prevention” to “Aborting a Heart Attack.” Dr. Sam has been honored with the American Heart Saver Award by the American Heart Association and has been named one of Hour Detroit’s “Top Docs” multiple times, a testament to the respect he has earned from both his peers and his community.
This dedication to public education is perhaps the most telling aspect of Dr. Sam’s character. It reveals a physician who understands that the battle against heart disease is won not just in the high-tech environment of the cath lab, but in the community centers and church basements where people learn to take control of their own health.
Dr. Samer Kazziha’s career is a powerful illustration of modern medical leadership. He is a physician who has mastered the intricate details of his specialty while never losing sight of the bigger picture. He is a leader who builds systems not for the sake of efficiency, but for the sake of better patient outcomes. He is a teacher who shares his knowledge freely, empowering both his colleagues and his community. In a world of increasing specialization, he remains a dedicated generalist in the truest sense of the word, a physician committed to the total health of his patients, his hospitals, and his community.
