Observation on therapeutic effect of balloon dilation in acute thrombus disease / 中国医师进修杂志

ABSTRACT

Objective To observe the therapeutic effect of balloon dilation in acute thrombus disease. Methods After coronary angiography, 137 patients with acute thrombus disease who were performed percutaneous coronary artery interventional therapy (PCI) from August 2010 to August 2012 were enrolled. In them, 53 patients (control group) didn′t undergo balloon dilation after PCI, and 84 patients(observation group)underwent balloon dilation after PCI. The intraoperative complications and the major adverse cardiac events (MACE) rate were observed. Results The rate of residue stenosis in observation group was lower than that in control group(6.7 ± 1.3)% vs. (17.1 ± 1.8)%, and there was significant difference (P0.05). The follow-up time was (0.9 ± 0.2) years. In control group, myocardial infarction occurred in 2 patients, 7 patients reviewed coronary angiography, and 2 patients underwent revascularization. In observation group, there was no MACE. Five patients reviewed coronary angiography, and no patient underwent revascularization. Conclusions The method of balloon dilation after PCI in acute thrombus disease is safe and feasible. It can reduce the incidence of MACE, and did not increase the rate of no-reflow or slow flow.
