Got heart problems? It’s probably one of two things, or both: Your diabetes medication or the Covid clot shot(s) you got. Do the research and you’ll see the science is there.
Millions of Americans rely on affordable diabetes medications to control blood sugar, but a major new study from Mass General Brigham has uncovered troubling findings about one of the most widely prescribed diabetes drugs in the U.S. – glipizide. According to research published in JAMA Network Open, glipizide is associated with a 13 percent higher risk of major cardiovascular events compared to newer alternatives, posing significant concerns for the long-term heart health of patients with Type 2 diabetes.
The study, led by Dr. Alexander Turchin of Brigham and Women’s Hospital, analyzed data from 48,165 patients with type 2 diabetes and moderate cardiovascular risk. All participants were on metformin as their base therapy and were tracked over a five-year period.
Patients were grouped based on the second medication they began using: glipizide, glimepiride, glyburide (all sulfonylureas) or DPP-4 inhibitors (a newer drug class). The research drew from real-world health records and insurance claims data through the BESTMED consortium, making its findings broadly applicable.
Key findings include:
Dr. Turchin emphasized that a 13 percent relative risk increase is considered clinically significant, especially in a patient population already vulnerable to heart disease. These findings challenge the long-held medical assumption that all sulfonylureas function similarly and carry equal risk. Glipizide, while effective and inexpensive, may be more harmful to heart health than previously recognized.
Although the exact mechanisms behind glipizide’s elevated heart risk remain unclear, researchers suspect the drug may interfere with cardiac receptors and the heart’s protective responses during periods of reduced blood flow. Interestingly, glipizide doesn’t appear to affect these receptors more aggressively than other drugs in its class, making the specific cause of the increased risk still unknown.
This discovery reinforces the need for personalized medicine and informed decision-making between doctors and patients. Cost and familiarity should not be the sole factors in selecting a diabetes medication, especially when cardiovascular health is on the line.
In addition to medication, patients can reduce both blood sugar and heart risks through natural strategies, such as:
Ultimately, this study is a wake-up call to reexamine common diabetes treatments. For patients and physicians alike, balancing effective glucose control with cardiovascular safety is vital for long-term health.
