Aspirin, Statins, and Primary Prevention: Opportunities for Shared Decision Making in the Face of Uncertainty.

PURPOSE OF REVIEW: The utility of aspirin and statins for primary prevention of atherosclerotic cardiovascular disease remains ambiguous in older adults. Current guidelines and recent data are vague and inconclusive. This review seeks to summarize the landscape of primary prevention of cardiovascular disease in older adults and explore the role of shared decision making. RECENT FINDINGS: Observational data suggest potential benefit of statin therapy in older adults. Aspirin is presently not recommended for primary prevention based on evidence from recent clinical trials. The implementation of shared decision making and decision aids in routine clinical practice remains challenging but may rise in coming years. Clinical trial data on the horizon may aid in solidifying guideline therapy for statin use. However, in the face of uncertainty, shared decision making between provider and patient should be utilized to determine whether pharmacotherapy may benefit older adults. Decision aids are an effective tool to guide this process.

Meta-analysis of the effect of colchicine on C-reactive protein in patients with acute and chronic coronary syndromes.

OBJECTIVE: The anti-inflammatory drug colchicine has recently shown benefits in the prevention of major adverse cardiovascular events (MACE) in patients with the acute coronary syndrome (ACS) and chronic coronary syndromes (CCS). This meta-analysis focuses on understanding Colchicine's effects on the high-sensitivity C-reactive protein (hs-CRP) to provide mechanistic insight to explain its clinical event reduction. METHODS: A computerized search of MEDLINE was conducted to retrieve journal articles with studies performed on humans from 1 January 2005 to 1 January 2022, using keywords: 'Colchicine AND Coronary', 'Colchicine AND CRP', and 'Colchicine AND Coronary Artery Disease'. Studies were included if they measured hs-CRP changes from baseline, and colchicine or placebo were given to patients with ACS or CCS. RESULTS: Thirteen studies with a biomarker subgroup population of 1636 patients were included in the hs-CRP meta-analysis. Of those 13 studies, 8 studies with a total population of 6016 reported clinical events defined as myocardial infarction (MI), stroke, cardiovascular death, periprocedural MI, repeat angina after PCI and repeat revascularization. Multivariate analysis revealed a weak negative correlation of -0.1056 ( P = 0.805) between change in CRP and clinical events. Overall, colchicine treatment resulted in a greater reduction in hs-CRP levels compared with placebo (Mean Difference: -1.59; 95% Confidence Interval, -2.40 to -0.79, P = 0.0001) and clinical events (Odds Ratio: 0.78; 95% Confidence Interval 0.64 to 0.95, P = 0.01). CONCLUSION: Colchicine therapy is associated with a reduction in hs-CRP and clinical events in patients with ACS and CCS. This finding supports colchicine's anti-inflammatory efficacy via CRP reduction to explain its clinical benefit.
