Incidence and Risk Factors of Left Ventricular Thrombus in Acute ST-Segment Elevation Myocardial Infarction Treated by Primary Percutaneous Coronary Intervention: A Meta-Analysis.

ABSTRACT:

Objective

Left ventricular thrombosis (LVT) is a common complication of acute ST-segment elevation myocardial infarction (STEMI). This study attempted to synthesize the available evidence to understand the incidence and risk factors of LVT in acute STEMI patients undergoing primary percutaneous coronary intervention (PCI).

Methods

We searched PubMed, Embase, Cochrane Library, and Web of Science for studies published from January 2001 to January 2022. The random-effects and fixed-effects model meta-analysis estimated pooled incidence, mean difference (MD), odds ratio (OR), and 95% confidence interval (CI). The Review Manager 5.4 software was used for meta-analysis performance.

Results

The results of meta-analysis showed that the incidence of LVT in acute STEMI treated by primary PCI was 4% (95% CI [0.03, 0.05]), and the overall pooled incidence in patients with anterior STEMI was 10.0% (95% CI [0.07, 0.12]). Anterior STEMI (OR = 11.93, 95% CI [6.25, 22.78], p = 0.0003), left anterior descending-related infarct (OR = 6.85, 95% CI [3.70, 12.66], p < 0.00001), left ventricular wall motion abnormalities (OR = 7.53, 95% CI [3.18, 17.82], p < 0.00001), and lower post-PCI LVEF (MD = 13.78, 95% CI [12.15, 15.41], p < 0.00001) were risk factors for post-PCI LVT.

Conclusion

The incidence of LVT after acute STEMI in the PCI era remains high. This study provides a preliminary overview of STEMI patients at risk for post-PCI LVT and will help the design of prospective randomized controlled trials for the management and prevention of LVT.

Project description:BackgroundAtrioventricular plane displacement (AVPD) reflects longitudinal left ventricular (LV) systolic function, and wall thickening (WT) regional radial LV function. The temporal evolution of these measures after STEMI with CMR has not been evaluated. We aimed to investigate how AVPD and WT are affected globally and regionally from the sub-acute to the chronic phase after ST-elevation myocardial infarction (STEMI).MethodsHealthy volunteers without cardiovascular disease and medication (controls, n = 20) and patients from the CHILL-MI study ( NCT01379261 ) prospectively underwent magnetic resonance imaging (MRI) 2-6 days and 6 months after STEMI (n = 77). CHILL-MI randomized STEMI-patients to cooling therapy initiated before reperfusion or standard of care. AVPD was measured at six points in three long axis cine images and wall thickening in short axis cine images. Infarction was quantified using late gadolinium enhancement (LGE) and used to define infarct and remote segments.ResultsThere were no difference in AVPD either at acute or chronic phase (p = 0.90 and p = 0.40) or WT (p = 0.85 and p = 0.99) between patients randomized to cooling therapy and standard of care. Therefore, the results are presented for the pooled cohort. Global AVPD was decreased in both the sub-acute (12 ± 2 mm, p < 0.001) and the chronic phase (13 ± 2 mm, p < 0.001) compared to controls (15 ± 2 mm) with a partial recovery of AVPD (p < 0.001) in the chronic phase. Patients with left anterior descending (LAD) and right coronary artery (RCA) infarcts had decreased AVPD in the chronic phase in both infarcted and remote segments. Mean WT was decreased in patients with LAD infarction both in the sub-acute and the chronic phase in both infarcted and remote segments. The decrease in WT in patients with RCA and left circumflex (LCx) infarcts was more affected in the infarcted segments, especially in the chronic phase.ConclusionAVPD was a global rather than regional marker of cardiac function in this STEMI study and this may explain the prognostic importance of local measurements of mitral annular plane systolic excursion (MAPSE). The decrease in WT in remote myocardium even in the chronic phase needs to be taken into consideration when combining functional measurements with infarct quantification for diagnosis of post-ischemic stunning and hibernation.
