Coronary artery diseaseEffect of Gradual Computerized Angioplasty on Outcomes of Patients Undergoing Coronary Stenting
Section snippets
Methods
Consecutive patients undergoing PCI at Hadassah-Hebrew University Medical Center were eligible for participation in the present trial. The institutional ethics committee approved the protocol, and all subjects provided informed consent before participation in the study. Patients with a 75% to 99% stenotic lesion after diagnostic angiography who were undergoing stenting were eligible for the present trial. Patients undergoing primary PCI for acute ST-elevation myocardial infarction and patients
Results
A total of 310 patients, with a total of 388 narrowings, were enrolled in the present trial. The baseline characteristics for the patient population are listed in Table 1. No significant differences were found between the control and CAPSID group, except for a greater prevalence of diabetes in the CAPSID group. Table 2 lists the angiographic data, including the quantitative coronary angiography comparison between the 2 groups. No significant difference was found between the groups in lesion
Discussion
The results of the present study have demonstrated that a novel computerized gradual balloon dilation system (CAPSID) reduces clinical events in a population of patients undergoing coronary stenting. This finding presumably resulted from the slower and more gradual balloon inflation using the CAPSID method, which is less traumatic to the vessel wall than standard manual inflation.
The mechanisms underlying early and late complications after angioplasty are complex; however, multiple studies in
