ABSTRACT=<p><bold>Background:</bold> Association between plasma pentraxin-3 (PTX-3) and clinical outcomes in patients with coronary artery disease (CAD) remains not fully determined. An updated meta-analysis of cohort studies was performed to systematically evaluate the association.</p><p><bold>Methods:</bold> Cohort studies evaluating the association between plasma PTX-3 and adverse outcomes [mortality and major adverse cardiovascular events (MACEs)] in adults with CAD were identified by systematic search of PubMed, Embase, and Web of Science databases. Only studies with multivariate analysis were included. A random-effects model incorporating the potential intrastudy heterogeneity was used for the meta-analysis.</p><p><bold>Results:</bold> A total of 16 studies including 11,007 patients were included. Pooled results showed that patients with highest level of PTX-3 were independently associated with higher risk of mortality [adjusted risk ratio (RR): 2.09, 95% CI: 1.60 to 2.74, <italic>p</italic> &lt; 0.001; <italic>I</italic><sup>2</sup> = 50%] and MACEs (adjusted RR: 1.80, 95% CI: 1.43 to 2.28, <italic>p</italic> &lt; 0.001; <italic>I</italic><sup>2</sup> = 49%). Subgroup analyses showed that the associations between PTX-3 and poor prognosis in CAD were consistent in patients with ST-segment elevation myocardial infraction, non-ST-segment elevation acute coronary syndrome, and stable CAD (<italic>p</italic> &lt; 0.05 for each subgroup). Besides, the association between PTX-3 and increased incidence of mortality and MACEs were consistent in short-term (within 1 year) and long-term (over 1 year) studies and in studies with or without adjustment of C-reactive protein (CRP) (<italic>p</italic> &lt; 0.05 for each subgroup).</p><p><bold>Conclusion:</bold> Higher plasma PTX-3 is associated with poor prognosis in patients with CAD, which may be independent of the CAD subtype, follow-up durations, and adjustment of CRP.</p>
