Clinical and angiographic profile of symptomatic patients undergoing percutaneous transluminal coronary angioplasty and drug-eluting stent implantation

V.S.R. Bhupal, P. Sampath Kumar


Background: There are limited number of studies in India which have looked at this clinical and angiographic characteristic of the disease. Thus, this study was conducted to assess the clinical and angiographic profile of symptomatic patients who underwent percutaneous transluminal coronary angioplasty (PTCA) and drug-eluting stent (DES) implantation.

Methods: This was an observational study conducted at a tertiary-care center in India between November 2014 and November 2015. A total of 106 consecutive patients who received either Cypher/Xience/BioMime stent presented with anginal symptoms were included in the study. Based on the type of stent received, patients were divided into two groups: (A) Limus group; (B) Paclitaxel group. Coronary angiogram was done in all the patients. Angioplasty data were collected from patient records. Angiographic profiles of the two groups were compared and analysed.

Results: Among the 106 patients, 54 patients were included in the Limus group and 52 patients were included in the Taxus stent. De novo lesions were found to be significantly higher in the Limus group (40(74%), p = 0.06) whereas the in-stent restenosis was found to be significantly higher in the paclitaxel group (22(42.3%), p = 0.08). At follow-up, the incidence of death was 0% and no patients suffered by myocardial infarction. One (1.8%), two (3.8%) patients from the Limus and Paclitaxel groups had target vessel revascularization, respectively.

Conclusions: Development of lesions in new areas rather than in-stent restenosis is the cause for angina in the majority of patients who underwent angioplasty presenting with anginal symptoms.
