Larger mean platelet volume was associated with a significantly higher risk of major adverse cardiac events in patients undergoing percutaneous coronary interventions (RR 1.81; 95% CI 1.29-2.55).
Meta-Analysis
Does larger mean platelet volume increase major adverse cardiac events in patients undergoing percutaneous coronary interventions?
Larger mean platelet volume is significantly associated with an increased risk of long-term MACE and mortality in patients undergoing PCI, suggesting its potential utility as an accessible indicator for risk stratification.
Relative Risk: 1.81 (95% CI 1.29–2.55)
Platelets with high hemostatic activity play a key role during percutaneous coronary interventions (PCI), and in recent years, mean platelet volume (MPV) has been looked upon as a crucial indicator of platelet reactivity. Thus, MPV may emerge as a potential gauge for the measurement of major adverse cardiac event (MACE) risks in PCI patients. This study aimed to conduct a meta-analysis illustrating the association between MPV and long-term MACE in PCI. The Cochrane Library, Pubmed, EMBASE, Ovid MEDLINE, and BIOSIS databases were used to search for relevant studies from their inception to 30 June 2019. All studies reporting incidences of MACE and MPV in PCI patients were retained. Data extraction was performed by three independent reviewers. A total of 33 studies were included in this meta-analysis. The results indicated that patients with MACE had a significantly larger MPV than those without, with an unstandardized mean difference (USMD) of 0.29 fL (95% CI, 0.04-0.54). The USMD of MPV in deceased patients was 0.39 fL (95% CI, 0.09-0.68). The results also indicated that patients with larger MPV were at greater risks of having MACE and higher incidence of mortality than those with smaller MPV, with a pooled risk ratio of 1.81 (95% CI, 1.29-2.55) and 2.34 (95% CI, 1.52-3.60), respectively. These findings indicate a significant association between larger MPV and MACE in PCI patients. Consequently, MPV, an easily accessible indicator, might be helpful in PCI patients' risk assessment and stratification.
Chen et al. (Thu,) conducted a meta-analysis in Percutaneous coronary interventions (PCI). Larger mean platelet volume vs. Smaller mean platelet volume was evaluated on Major adverse cardiac events (MACE) (RR 1.81, 95% CI 1.29-2.55). Larger mean platelet volume was associated with a significantly higher risk of major adverse cardiac events in patients undergoing percutaneous coronary interventions (RR 1.81; 95% CI 1.29-2.55).
