Popis: The usefulness of aspirin in patients without a cardiovascular history continues to be a subject of controversy. Objectives 1. Perform an updated meta-analysis on the use of aspirin in primary cardiovascular prevention. 2. Analyze the results by risk. Methods This meta-analysis was performed according to the PRISMA guidelines. The primary endpoint was cardiovascular death, AMI, and ischemic stroke. The measures of effect size are expressed as odds ratios. The level of statistical significance was established at 0.05.

Figure 1 Results Thirteen works were considered for the analysis (Table 1). A total of 164,225 patients were included, 82,900 in the aspirin arm and 81,325 in the control group. A reduction of the primary endpoint was observed in the AAS group (OR 0.90, 95% CI 0.85–0.94). No differences by risk group (Figure 1). Risk of severe bleeding was significantly higher in patients treated with ASA (OR 1.45, 95% CI 1.34–1.56), this difference was maintained by risk (Figure 1). Acknowledgement/Funding None
