Could a common anti-inflammatory drug help protect the hearts of people with diabetes?

If you have type 2 diabetes and are at high risk for heart disease, your arteries can become stiff and rigid over time, which puts extra strain on your heart. This study tested whether a low-dose, daily anti-inflammatory drug called colchicine could help. In a 26-week trial with 100 participants, those who took colchicine saw a significant improvement in a key measure of artery stiffness compared to those who took a placebo. This suggests the drug may help keep arteries more flexible. However, the treatment did not have a significant effect on 24-hour blood pressure readings or on a marker of kidney stress (urine albumin-to-creatinine ratio). The findings point to a possible new way to protect the heart in high-risk diabetes patients by targeting inflammation and artery health directly, which could complement existing treatments. The researchers note that more studies are needed to confirm these effects and understand exactly how it works.
