Could a Common Diabetes Medication Increase Cardiovascular Risks?

Synopsis
Key Takeaways
- Glipizide is linked to higher cardiovascular risks.
- It may cause heart failure, hospitalizations, and death.
- Comparison with DPP-4 inhibitors shows significant differences.
- Type 2 diabetes management must consider cardiovascular health.
- Further research is needed to understand the mechanisms involved.
New Delhi, July 26 (NationPress) A widely prescribed medication for type 2 diabetes in the US, Glipizide, may be associated with a higher rate of cardiovascular issues, according to a recent study. Researchers from Mass General Brigham analyzed national data involving nearly 50,000 patients treated with various sulfonylureas. Their findings indicated that Glipizide was linked to an increased incidence of heart failure, related hospitalizations, and mortality when compared to dipeptidyl peptidase-4 (DPP-4) inhibitors. These results were published in the prestigious JAMA Network Open.
“Individuals living with type 2 diabetes face an elevated risk of severe cardiovascular events such as stroke and cardiac arrest,” stated Alexander Turchin, the study's corresponding author from the Division of Endocrinology at Brigham and Women’s Hospital (BWH).
“While sulfonylureas are both popular and cost-effective medications for diabetes, there is a significant lack of extensive clinical data regarding their impact on heart health compared to more neutral options like DPP-4 inhibitors,” he added.
Type 2 diabetes is a prevalent chronic condition with increasing global incidence. Those with this condition have a heightened risk of serious cardiovascular events such as coronary ischemia, stroke, and heart failure. Therefore, addressing cardiovascular risk is a critical component of diabetes management.
The study encompassed 48,165 patients diagnosed with type 2 diabetes and moderate cardiovascular risk, receiving care at ten diverse study sites nationwide.
The researchers evaluated the five-year risk of significant adverse cardiovascular events in patients treated with various sulfonylureas (including glimepiride, glipizide, or glyburide) or DPP-4 inhibitors, alongside metformin, a primary diabetes medication.
Results revealed that Glipizide was associated with a 13% increase in cardiovascular risk compared to DPP-4 inhibitors, while glimepiride and glyburide exhibited comparatively smaller and less defined effects.
“This study emphasizes the necessity of assessing each medication within a pharmacological class on its individual merits,” Turchin remarked.
The research team also advocated for further exploration to reveal the underlying mechanisms.
