Abstract:

Objective

To evaluate the clinical efficacy of direct stenting during primary percutaneous coronary intervention (PCI) for patients with acute ST-segment elevation myocardial infarction (STEMI) with high thrombus burden.

Methods

We retrospective analyzed the clinical data of 298 patients with STEMI with high thrombus burden treated by PCI at the Department of Emergency Medicine of the Affiliated Hospital of Inner Mongolia Medical University between March 2016 and February 2018. The patients were divided into two groups according to different treatment methods for target lesions before stent implantation, namely, balloon predilation+ PCI group (control group) and direct PCI without balloon predilation group (experimental group). The chi-square test was used to compare the incidence of no-reflow phenomenon (NR) and rates of ST-segment resolution and major adverse cardiac events (MACE) between the two groups. Factors with a statistically significant difference in univariate analysis were included into Logistic regression analysis to identify the independent risk factors for NR.

Results

There were 31 (10.4%, 31/298) patients with no reflow after PCI in the two groups, including 3 (1.2%, 3/249) in the experimental group and 28 (57.1%, 28/49) in the control group; there was a statistically significant difference between the two groups (χ2=137.453, P<0.001). For patients with a ST-segment elevation drop rate< 50% in the infarcted artery within 2 h after surgery, there were 2 (0.8%, 2/249) cases in the experimental group, and 18 (36.7%, 18/49) cases in the control group; there was a statistically significant difference between them (χ2=162.213, P<0.001). The rates of acute heart failure within 30 days after surgery [18 (36.7%) vs 21 (8.4%, 21/249, χ2=28.830, P<0.001] and cardiac death after primary PCI [8 (16.3%, 8/49) vs 0 (0%, 0/49), χ2=42.216, P<0.001] were significantly higher in the control group than in the experimental group. Logistic regression analysis demonstrated that balloon predilation was positively correlated with NR (odds ratio=47.594, P<0.001).

Conclusion

Direct stenting without balloon predilation can effectively reduce the incidence of NR and MACE and decrease mortality when performing primary PCI for patients with high thrombus burden STEMI.
