BACKGROUND: Parathyroid hormone (PTH) is a novel promising biomarker that can predict hospitalization, functional status and mortality in patients who suffered heart failure with preserved ejection fraction (HFpEF). OBJECTIVE: We aimed to investigate the association of serum PTH levels and measures of disease severity (NYHA functional class, NT-proBNP, CRP, EF, Troponin I) in patients with HFpEF. METHODS: A total of consecutive 58 outpatients with HFpEF and 30 controls were prospectively studied. All patients underwent laboratory tests, including NT-proBNP and PTH analyses. RESULTS: PTH, NT-proBNP, troponin I, and CRP levels were significantly higher in patients with HFpEF when compared with control group (54.61 ± 31.02 vs 40.40 ± 14.22 pg/ml, p < 0.05; 126.05 ± 162.94 vs 44.57 ± 14.95 pg/ml, p < 0.01; 0.011 ± 0.013 vs 0.004 ± 0.001 ug/L, p < 0.01; 4.65 ± 4.24 vs 1.63 ± 0.97 mg/L, p < 0.01, respectively). Left atrium was found to be more enlarged in HFpEF patients (LAVI = 36 ± 18 vs 28 ± 11 ml/m2, p < 0.01). Most indices of left ventricular diastolic function were more severely impaired compared to controls (p < 0.05). There was no correlation between PTH and CRP, troponin I, LVMI, LV volumes, LV diameters, E/E', age, and BMI in both groups (p = NS). There was strong positive correlation between PTH and NT-proBNP levels in all study participants (r = 0.359; p < 0.01). CONCLUSION: PTH together with other markers of heart failure may provide valuable information both in the diagnosis and staging of heart failure syndromes.

Background: The prognostic relevance of hematological parameters in cardiovascular diseases has been well demonstrated. The purpose of the present study is to investigate the association between the hematological parameters, particularly neutrophil to lymphocyte ratio (NLR), and outcomes of aortic dissection (AD). Methods: Two hundred patients diagnosed with AD were retrospectively recruited and compared with 76 subjects with ascending aortic dilatation (AAD) and 92 subjects with normal aortic diameters. The independent relation between hematological parameters and in-hospital mortality was analyzed by regression analysis. Results: The NLR was significantly higher in the AD group compared to the AAD and control groups (median 8.83 [8.13] vs. median 1.95 [1.10] vs. median 1.71 [0.77], respectively; p = 0.01). The NLR was higher in the de-ceased (n = 57) compared to the surviving patients (n = 143) (median 10.37 [10.86] vs. median 7.84 [8.17]; p = 0.01). Receiver operating curve (ROC) analysis revealed that a NLR measurement higher than > 8.78 predicted in-hospital mortality for patients with acute aortic dissection with a sensitivity of 67.4% and a specificity of 57.2% (AUC: 0.672; p = 0.01). In multivariate logistic regression analysis, increased aortic diameter, acute dissection, and increased levels of NLR remained as the independent markers of in-hospital mortality within the study population. Conclusions: In patients with AD, NLR levels were increased compared to patients with AAD and controls and were independently associated with in-hospital mortality. This finding implicates that admission hematological parameters may have clinical importance in evaluating the mortality risk in patients with AD.
