چکیده

BACKGROUND Impaired renal function is a marker of poor prognosis in patients with acute myocardial infarction (AMI). The aim of the study was to assess the incidence and independent predictors of stroke in population of patients with AMI treated invasively and concomitant impaired renal function (IRF). METHODS We analyzed 2,520 consecutive AMI patients admitted to our Center between 2003 and 2007 and treated with percutaneous coronary intervention. The whole population was divided into patients with IRF, defined as glomerular filtration rate < 60 mL/min/1.73 m(2) or contrast induced nephropathy (IRF group, n = 933; 37.02%) and patients without IRF (control group, n = 1587; 62.98%). The IRF group was subjected to further analysis. Data on long-term follow-up were screened to identify the patients who experienced stroke. RESULTS During median of 25.5 months of follow-up 52 (2.07%) the patients experienced stroke - 33 (3.54%) in the IRF group and 19 (1.2%) patients in the control group. The risk of major adverse cardiovascular events in the IRF group, including repeated AMI (68.8 vs.14.9%, p < 0.001) and death (45.5 vs. 25.1%, p < 0.05) was significantly higher in patients with stroke. Previous stroke (HR 6.85), female gender (HR 3.13), as well as STEMI anterior (HR 2.55) were independent risk factors of stroke in this population. CONCLUSIONS Patients with AMI treated invasively and concomitant IRF were at higher risk of stroke occurrence in the future. Stroke was associated with poor outcome in the studied population. Independent predictors of stroke in patients with IRF and AMI treated invasively were different from commonly recognized stroke predictors.

  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...
