Imagine this: A common, affordable medication, already used for gout, could significantly lower your risk of heart attack and stroke. Sounds almost too good to be true, doesn’t it? Well, a new review published in the Cochrane Database of Systematic Reviews suggests exactly that.
The study delves into the potential of low-dose colchicine, a drug typically prescribed for gout, to act as a shield against cardiovascular events. But how does this work?
Cardiovascular disease often stems from chronic, low-grade inflammation, a silent threat that can trigger heart attacks and strokes. Colchicine steps in with its anti-inflammatory properties, potentially offering a new line of defense for those with heart conditions.
A Promising Look at Cardiovascular Risk
The review analyzed data from 12 randomized controlled trials, encompassing nearly 23,000 individuals with a history of heart disease, heart attack, or stroke. These participants took colchicine at doses of 0.5 mg once or twice daily for at least six months. The majority of participants were male (~80%) with an average age range of 57 to 74 years old. Half received colchicine, while the other half received either a placebo or no additional treatment.
The results? Those taking low-dose colchicine showed a reduced likelihood of experiencing a heart attack or stroke. For every 1,000 people treated, there were nine fewer heart attacks and eight fewer strokes compared to those not taking the drug. While serious side effects weren’t identified, some patients experienced mild and temporary stomach or digestive issues.
“Among 200 people with cardiovascular disease—where we would normally expect around seven heart attacks and four strokes—using low-dose colchicine could prevent about two of each,” explains Dr. Ramin Ebrahimi, co-lead author from the University of Medicine in Greifswald, Germany. “Reductions like this can make a real difference for patients who live with ongoing, lifelong cardiovascular risk.”
A New Chapter for an Old Drug
Given that cardiovascular diseases are a leading cause of death worldwide, colchicine presents a promising, inexpensive, and accessible option for secondary prevention in high-risk patients.
“These results come from publicly-funded trials repurposing a very old, low-cost drug for an entirely new use,” notes Lars Hemkens, senior author from the University of Bern, Switzerland. “It shows the power of academic research to reveal treatment opportunities that traditional drug development often overlooks.”
But here’s where it gets controversial… The evidence is less clear on whether colchicine impacts overall death rates or the need for procedures like coronary revascularization. The studies didn’t provide information on whether the drug improves quality of life or reduces hospital stays. The authors emphasize that further research is needed in these areas.
