چکیده
INTRODUCTION AND OBJECTIVES The aim of this study was to analyze the prevalence, risk factors, and short- and long-term prognosis of patients with acute coronary syndrome and normal renal function who developed percutaneous coronary intervention-associated nephropathy. METHODS This was an observational, retrospective, single-center study with a prospective follow-up of 470 consecutive patients hospitalized for acute coronary syndrome (not in cardiogenic shock) who underwent percutaneous coronary intervention, with no preexisting renal failure (admission creatinine ≤ 1.3mg/dL). Percutaneous coronary intervention-associated was defined as an increase in baseline creatinine ≥ 0.5 mg/dL or ≥ 25% baseline. The mean follow-up was 26.7 (14) months. RESULTS Of the 470 patients, 30 (6.4%) developed percutaneous coronary intervention-associated nepfhropathy. The independent predictors for acute renal failure were admission hemoglobin level (odds ratio = 0.71) and maximum troponin I level prior to the procedure (odds ratio = 1.02). During the long-term follow-up, the patients whose renal function deteriorated had a higher incidence of total mortality (5 [16.7%] vs 27 [6.1%]; P = .027). In the Cox regression analysis, percutaneous coronary intervention-associated nepfhropathy was not an independent predictor for total mortality, but could be a predictor for cardiac mortality (hazard ratio=5.4; 95% confidence interval 1.35-21.3; P = .017). CONCLUSIONS Percutaneous coronary intervention-associated nephropathy in patients with acute coronary syndrome and normal preexisting renal function is not uncommon and influences long-term survival.

Background: Cardiovascular diseases are global problems. They are causes of death in about 43% of people worldwide and may become the most widespread reason of death by 2020. The prognosis is directly dependent to immediate diagnosis and on time treatment. Introduction of new biochemical markers as the early diagnosis of complications after coronary revascularization is very important in this p...

Introduction: No-reflow phenomenon in coronary vessels, manifested in some patients with reperfused acute myocardial infarction (MI), is associated with poor clinical and functional outcomes. Therefore, evaluation of predisposing risk factors can be helpful in risk assessment and identification of patients at higher risk. Herein, we aimed to study the predictive factors for the development of...
