Prophylactic Effect of Aspirin and Other Medicine on Cerebral Infarction for Patients with Cardiovascular Diseases Risk Factors: A Systemic Review and Meta-Analysis.

Stroke, as a type of cardiovascular disease (CVD) and cerebrovascular disease, has the risk of causing death or disability in patients. Aspirin, as an antipyretic and analgesic drug, can also treat or prevent CVDs. Previous studies have had conflicting results on the preventive effect of aspirin on cerebral infarction for patients with CVD risk factors. This review was carried out through a meticulous search of the Web of Science and PubMed databases. Articles were included or excluded based on predefined criteria. In terms of heterogeneity, a fixed effect model was utilized when I2 was less than 50%. Conversely, if the studies were deemed clinically comparable, a random effect model was implemented. The findings suggest that medical intervention significantly mitigates the risk of cerebral infarction in patients predisposed to CVDs [odds ratio (OR), 0.85; 95% confidence interval (CI), 0.74-0.98; P = 0.03]. Interestingly, the preventive efficacy of medication appears to be higher in men (OR, 0.82; 95% CI, 0.72-0.94; P = 0.004) than in women (OR, 0.84; 95% CI, 0.69-1.01; P = 0.06). However, in terms of stroke prevention, no significant difference was observed between the use of aspirin (OR, 0.90; 95% CI, 0.76-1.06; P = 0.19) and other medications (OR, 0.65; 95% CI, 0.31-1.38; P = 0.26).
