- W64154321 abstract "Background: Contrast induced nephropathy (CIN) is an important complication post percutaneous coronary intervention (PCI). We examine the risk factors for developing CIN in patients with normal baseline renal function so that prophylactic measures may be undertaken to prevent its development. Methods: A cohort of 5086 patients with normal baseline renal function (defined as serum creatinine <1.5mg/dl) who did not receive prophylactic treatment while undergoing PCI (primary or elective) between May 1996 to March 2007 in our centre was enrolled in the study. We examine the occurrence of CIN (defined as >25% increase from baseline creatinine within 48 hours post PCI) in 3036 subjects of this cohort with available creatinine data and aim to identify the clinical predictors. Results: CIN occurred in 7.3% of the patients. The mean age of these patients was 57.5 yrs, 78.7% were men, and 34.6% had diabetes mellitus. Clinical predictors for CIN were age (OR 6.4, 95% CI 0.1–13.3, p=0.042), female gender (OR 2.0, 95% CI 1.5–2.7, p=0.001), lower left ventricular ejection fraction (OR 1.02, 95% CI 1.01–1.04, p=0.01), anemia with hemoglobin <11mg/dl (OR 1.5 (95% CI 1.01–2.4, p=0.044) and systolic hypotension with blood pressure <100mmHg on admission(OR 1.5, 95% CI 1.01–2.2, p=0.004). While there was no increase in the incidence of CIN among diabetics and nondiabetics (8.2% vs 6.8%, p=0.18), those who are on insulin therapy are at the highest risk compared with diabetics on diet control and oral hypoglycemic drugs (18.9% vs 3.6% vs 6.8%, p=0.001). There was no significant difference between patients who underwent primary vs elective PCI (7.0% vs. 6.6% p=0.75). Patients who developed CIN had higher mortality rate at 1 month (14.5% vs 1.1%, p<0.001) and 6 month (17.8% vs 2.2%, p<0.001) Conclusion: Patients with normal baseline renal function undergoing PCI are also at risk of developing CIN with resultant higher mortality. Age, female, insulin dependent diabetes mellitus, hypotension, anemia, low left ventricular ejection fraction are predictors of CIN. Such patients should also be considered CIN prophylactic therapy." @default.
