INTRODUCTION: Despite advances in medicine, chronic systolic heart failure (CHF) due to hypertension still constitutes a serious clinical challenge.
OBJECTIVES: The aim of the study was to determine risk mortality factors in a 3-year follow-up of patients with CHF due to hypertension.
PATIENTS AND METHODS: The study involved 140 consecutive stable inpatients with CHF (left ventricular end diastolic diameter >57 mm; left ventricular ejection fraction [LVEF] <40%), without epicardial artery stenosis (>30% vessel lumen), significant heart defect, diabetes, neoplastic, disease, or chronic kidney disease, with a minimum 5-year history of hypertension, and administration of angiotensin-converting enzyme inhibitors (or angiotensin II receptor antagonists), β-adrenolytics, spironolactone and furosemide for 3 or more months. The follow-up began on admission to the hospital after laboratory tests, resting electrocardiogram and echocardiogram, six-minute walk test, coronarography, and endomyocardial biopsy. Late follow-up data was obtained from the follow-up visits or by telephone.
RESULTS: The analysis involved 130 of 140 patients aged 47.8 ±7.9 years. The 3-year mortality rate was 18.5%. Independent risk factors for death were LVEF (hazard ratio [HR], 0.881; 95% confidence interval [CI], 0.797-0.975, P <0.05), serum glucose (HR, 1.266; 95% CI, 1.085-1.627; P <0.05), N-terminal pro-B-type natriuretic peptide (NT-proBNP; HR, 1.369; 95% CI, 1.166-1.671; P <0.001), and bilirubin levels (HR, 1.057; 95% CI, 1.021-1.094; P <0.01).
CONCLUSIONS: Beside LVEF and serum NT-proBNP, other independent risk factors for death in patients with CHF due to hypertension are glucose and bilirubin levels.
