Impact of Non-Infarct-Related Artery Disease on Infarct Size and Outcomes (from the CRISP-AMI Trial)

The Inhibition of Evolocumab on Non-Infarct-Related Artery Disease in Patients with ST-Elevation Myocardial Infarction

Purpose

The effects of combing evolocumab and statin on the clinical outcome and physiological function of coronary arteries in STEMI patients with non-infarct-related artery (NIRA) disease are still unclear.

Methods

A total of 355 STEMI patients with NIRA were enrolled in this study, who underwent combined quantitative flow ratio (QFR) at baseline and after 12 months of treatment with statin monotherapy or statin plus evolocumab.

Results

Diameter stenosis and lesion length were significantly lower in the group undergoing statin plus evolocumab. While the group exhibited significantly higher minimum lumen diameter (MLD), and QFR values. Statin plus evolocumab (OR = 0.350; 95% CI: 0.149-0.824; P = 0.016) and plaque lesion length (OR = 1.223; 95% CI: 1.102-1.457; P = 0.033) were independently associated with rehospitalization for unstable angina (UA) within 12 months.

Conclusion

Evolocumab combined with statin therapy can significantly improve the anatomical and physiological function of the coronary arteries and downregulate the re-hospitalization rate due to UA in STEMI patients with NIRA.

Fractional flow reserve-guided complete revascularization versus culprit-only revascularization in acute ST-segment elevation myocardial infarction and multi-vessel disease patients: a meta-analysis and systematic review

Background

Approximately 30–50% patients with acute ST-segment elevation myocardial infarction (STMEI) were found to have non-infarct-related coronary artery (IRA) disease, which was significantly associated with worse prognosis. However, challenges still remain for these patients: which non-infarct-related lesion should be treated and when should the procedure be performed? The present study aims to investigate Fractional flow reserve (FFR)-guided complete revascularization (CR) in comparison to culprit-only revascularization (COR) in patients with ST-segment elevation myocardial infarction (STEMI) and multi-vessel disease (MVD).

Methods

Three appropriate randomized controlled trials (RCTs) were selected from the PubMed/Medline, EMBASE, and the Cochrane library /CENTRAL databases. 1631 patients (688 patients underwent FFR-guided CR and 943 patients underwent COR) following-up 12–44 months was evaluated.

Results

FFR-guided CR significantly reduced major adverse cardiac event (MACE) (OR 0.47, 95% CI: 0.35–0.62, P < 0.00001) and ischemia-driven repeat revascularization (OR 0.36, 0.26–0.51, P < 0.00001), as compared to COR. However, there is no difference in all-cause mortality (OR 1.24, 0.65–2.35, P = 0.51).

Conclusions

In patients with STEMI and MVD, FFR-guided CR is better than COR in terms of MACE and ischemia-driven repeat revascularization, while there are almost similar in all-cause mortality.
