A significant global health concern, cardiovascular disease (CVD) is characterized by a rising prevalence and accompanying mortality rates. It is crucial to implement primary and secondary prevention strategies, particularly in resource-scarce settings. Polypills, which combine blood pressure, cholesterol, and homocysteine drugs, hold significant potential for lowering the risk of CVD. This study follows PRISMA meta-analysis guidelines. Two researchers conducted an extensive literature search. Inclusion criteria encompassed RCT design, polypill use, a four-week duration, and one meta-analysis outcome. Primary outcomes included MACE and CV mortality, while secondary outcomes encompassed SBP and LDL-C changes. Data extraction was performed independently, and conflicts were resolved. Review Manager 5.4 with random effects was employed for statistical analysis, and ROB 2.0 bias evaluation was conducted. The study reported CVD mortality and MACE risk ratios (RRs) with 95% CIs, as well as SBP and LDL-C weighted mean differences (MD). A total of 24 trials were included in this meta-analysis. The results revealed that the polypill was associated with a decreased risk of CVD mortality and major adverse cardiovascular events (MACE). Additionally, a significant reduction in systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-C) was observed. This meta-analysis showed that polypill is a viable medication for reducing the risk of CVD mortality and MACE. It is also a beneficial medication for lowering LDL-C levels and SBP.
