Abstract：Objective To investigate the correlation between inter-arm difference in systolic blood pressure (IADSBP) and cardiovascular diseases through Meta-analysis.Methods The databases of Cochrane Library, PubMed, Medline, EMbase, CNKI and WanFang Database were retrieved with computer (until Sept. 30, 2014) for searching the cohort studies, case controlled studies and observation studies related to the correlation between IADSBP and cardiovascular diseases. All documents were read and screened strictly according to exclusion criteria. The data were extracted and given a Meta-analysis by using Revman5.3 software.Results There were totally 7 documents and 8 cross-section observation studies included (all in English) involving 5263 cases. All included studies were divided into group 1 (IADSBP≥15 mmHg) and group 2 (IADSBP<15 mmHg). The Meta-analysis showed that incidence of chronic heart disease (CHD) had no statistical difference between 2 groups (RR=1.03, 95%CI: 0.67~1.58, P=0.88). The simultaneous detection in subgroups showed (RR=0.87, 95%CI: 0.59~1.30,P=0.51) and those of non-simultaneous detection showed (RR=1.13, 95%CI: 0.55~2.31,P=0.73), and the results also indicated that CHD incidence had no statistical difference between 2 groups.Conclusion IADSBP (≥15 mmHg) is not significantly correlated to cardiovascular diseases, so it cannot be taken as risk predictive factor of CHD.
