Percutaneous coronary intervention versus coronary artery bypass grafting among patients with left ventricular systolic dysfunction: a systematic review and meta-analysis

Efficacy of Colchicine for Prevention of Stroke and Adverse Cardiovascular Events: A Meta-analysis of 16 Randomized Controlled Trials

BACKGROUND

Colchicine has been shown to reduce adverse cardiovascular events (ACE) and stroke among patients with coronary artery disease. However, its efficacy with short- and long-term use and risk of stroke has not been well studied, with conflicting results to date.

OBJECTIVE

We sought to evaluate the efficacy of colchicine for the prevention of stroke and other cardiovascular outcomes and to evaluate the effect of short- and long-term use.

METHODS

We performed a systematic literature search on PubMed, EMBASE, and Clinicaltrial.gov for relevant randomized controlled trials (RCTs) from inception until July 20th, 2024. Odds ratios (ORs) were pooled using a random-effect model, and a p value of < 0.05 was considered statistically significant.

RESULTS

A total of 16 RCTs with 24,967 patients were included (12,538 in colchicine group and 12,429 in the control group) in the analysis. Pooled analysis of primary outcomes showed that risk of incidence of stroke was comparable between colchicine and placebo groups (OR 0.78, 95% confidence interval [CI] 0.59-1.02, p = 0.07). Pooled analysis of secondary outcomes showed that colchicine significantly reduced the risk of incidence of ACE by 33% (OR 0.67, 95% CI 0.54-0.82, p < 0.001), and myocardial infarction by 21% (OR 0.79, 95% CI 0.65-0.95, p = 0.01) compared with placebo. However, the risk of all-cause mortality (OR 0.98, 95% CI 0.79-1.21, p = 0.83) and cardiovascular mortality (OR 0.78, 95% CI 0.56-1.08, p = 0.14) were comparable between both groups of patients.

CONCLUSION

Colchicine was associated with an overall reduction in the risk of incidence of ACE and MI; however, no such effect was observed with mortality and stroke.

Association between testosterone replacement therapy and cardiovascular outcomes: A meta-analysis of 30 randomized controlled trials

BACKGROUND

The Cardiovascular safety of testosterone replacement therapy (TRT) among men with hypogonadism is not well established to date. Hence, we sought to evaluate the cardiovascular disease (CVD) outcomes among patients receiving testosterone therapy by using all recently published randomized controlled trials.

METHODS

We performed a systematic literature search on PubMed, EMBASE, and Clinicaltrial.gov for relevant randomized controlled trials (RCTs) from inception until September 30th, 2023.

RESULTS

A total of 30 randomized trials with 11,502 patients were included in the final analysis. The mean age was ranging from 61.61 to 61.82 years. Pooled analysis of primary and secondary outcomes showed that the incidence of any CVD events (OR, 1.12 (95%CI: 0.77-1.62), P = 0.55), stroke (OR, 1.01 (95%CI: 0.68-1.51), P = 0.94), myocardial infarction (OR, 1.05 (95%CI: 0.76-1.45), P = 0.77), all-cause mortality (OR, 0.94 (95%CI: 0.76-1.17), P = 0.57), and CVD mortality (OR, 0.87 (95%CI: 0.65-1.15), P = 0.31) was comparable between TRT and placebo groups.

CONCLUSION

Our analysis indicates that for patients with hypogonadism, testosterone replacement therapy does not increase the CVD risk and all-cause mortality.
