Background
Chronic kidney disease is a frequent comorbidity in heart failure (HF), associated with increased mortality. The impact of temporal evolution of kidney function in HF prognosis is largely unknown. We evaluated the effect of renal function over time in all-cause mortality among ambulatory patients with HF.Methods
We retrospectively analyzed data from 560 patients with HF with left ventricular systolic dysfunction followed for a median of 25.1 months at an outpatient clinic. Demographics and comorbidities were collected at baseline. Creatinine values were abstracted from records at each clinical visit. Kidney function was assessed by estimated glomerular filtration rate (eGFR) and was categorized into 3 classes. Extended Cox models were performed to study the association between time-varying eGFR and death.Results
Patients’ mean age was 67.5 ± 13.9 years, 67.0% were men, 46.1% had ischemic etiology, the majority had moderate-to-severe left ventricular systolic dysfunction, and 45.9% had chronic kidney disease at baseline. The eGFR declined approximately 9.0 mL/min/1.73 m2 over 5 years. In crude analysis, time-varying eGFR had a significant dose-dependent association with death (hazard ratio [HR] = 1.34, 95% confidence interval [CI]: 1.03-1.75 for eGFR between 30 and 60 mL/min/1.73 m2; HR = 1.55, 95% CI: 1.11-2.17 for <30 mL/min/1.73 m2). The prognostic value of time-varying eGFR was totally explained by baseline comorbidities, indicators of HF severity and drugs (adjusted HR = 1.11, 95% CI: 0.83-1.48; HR = 1.19, 95% CI: 0.79-1.80, for eGFR 30-60 and <30 mL/min/m2, respectively).Conclusions
Time-varying kidney function is not independently related to poor prognosis in HF. Rather than directly affecting survival, renal impairment is probably a surrogate marker of HF severity. 相似文献2.

Introduction and objectivesDespite increased awareness of sex disparities in care and outcomes of acute myocardial infarction (AMI), there appears to have been no consistent attenuation of these differences over the last decade. We investigated differences by sex in management and 30-day mortality using the European Society of Cardiology Acute Cardiovascular Care Association quality indicators (QIs) for AMI.MethodsProportions and standard errors of the 20 Acute Cardiovascular Care Association QIs were calculated for 771 patients with AMI who were admitted to the cardiology departments of 2 tertiary hospitals in Portugal between August 2013 and December 2014. The association between the composite QI and 30-day mortality was derived from logistic regression.ResultsSignificantly fewer eligible women than men received timely reperfusion, were discharged on dual antiplatelet therapy and high-intensity statins, and were referred to cardiac rehabilitation. Women were less likely to receive recommended interventions (59.6% vs 65.2%; P < .001) and also had higher mean GRACE 2.0 risk score-adjusted 30-day mortality (3.0% vs 1.7%; P < .001). An inverse association between the composite QI and crude 30-day mortality was observed for both sexes (OR, 0.08; 95%CI, 0.01-0.64 for the highest performance tertile vs the lowest).ConclusionsPerformance in AMI management is worse for women than men and is associated with higher 30-day mortality, which is also worse for women. Evidence-based QIs have the potential to improve health care delivery and patient prognosis in the overall AMI population and may also bridge the disparity gap between women and men.Full English text available from: www.revespcardiol.org/en 相似文献
