The Prognosis of Primary Percutaneous Coronary Intervention after One Year Clinical Follow Up

Objectives: The aim of this study was to evaluate the clinical outcomes, one year after primary percutaneous coronary intervention(PCI).

Patients and Methods: From September 2009 to March 2012, primary PCI was performed on 70 cases, and the data relating to their catheterization were recorded. Peri-interventional treatment data included PCI with drug-eluting or bare-metal stent or balloon angioplasty alone.

Results: The mean age of the patients was 61.34+11.31 years, and 72.9% of them were males. The ratios of patients with diabetes, hypertension and, hyperlipidemia were 61.4%, 71.4%, and 52.9% respectively.
In clinical follow-up, total incidence of death was 4.3%, with no death occurring during 30 days. However, 3 patients died after one-year, of which one patient (1.4%) had cardiac problem and the other 2 (2.9%) died because of non-cardiac reasons. Target vessel revascularization, reinfarction within 30 days, and mechanical complication or stroke were not found in any of the patients. Patients with hypertension (6%) and those with LAD ST-elevation myocardial infarction (5%) died after one year (P= 0.263 and P= 0.319 respectively). However, no mortality was reported in patients with RCA and LCX ST-elevation myocardial infarction. Of subjects with multivessel disease, 7% died after one-year (P= 0.161), but there was no reported mortality in those with single vessel disease.

Conclusions: The prognosis was satisfactory in patients undergoing PCI after one year clinical follow up.
