Background. Anemia and chronic renal failure (CRF) are frequent comorbidities in patients with heart failure (HF), and they have been reported to be associated with increased mortality and hospitalization rates. HF, anemia, and CRF have been reported to interact with each other forming a vicious cycle termed cardio-renal-anemia syndrome. The aim of the present study was to evaluate the association of HF, anemia, and CRF using data from the large-scale "Heart Failure Prevalence and Predictors in Turkey (HAPPY)" study.
Patients and methods. Among the HAPPY cohort, 3,369 subjects who had either left ventricular dysLVD) or normal left ventricular function on echocardiography or normal serum NT-proBNP levels were included in this analysis. Results. The prevalence of anemia and CRF was significantly higher in patients with LVD compared with subjects with normal ventricular 20.7% vs. 4.0% and 19.0% vs. 3.7%, respectively; p< 0.001 for each). Binary logistic regression analyses for the presence of LVD, anemia, and CRF demonstrated that each one was an independent predictor for the presence of the others.
Conclusion. These findings point to the presence of cardio-renal-anemia syndrome and the necessity of treating these comorbidities in patients with HF.
