Aim: N-terminal pro-B-type natriuretic peptide (NT-proBNP) and high-sensitivity cardiac troponin T (hs-cTnT) associate with structural heart disease and heart failure risk in individuals without known cardiovascular disease (CVD). However, few data are available regarding whether factors influencing levels of these two biomarkers are similar or distinct. We performed serial measurement of NT-proBNP and hs-cTnT in a contemporary multiethnic cohort with extensive phenotyping, with the goal of identifying their respective biological determinants in a population without known or suspected CVD. Methods: We evaluated 1877 participants of the Dallas Heart Study who had NT-proBNP and hs-cTnT measured and were free from clinical CVD at the each of its two examinations (2000–2002 and 2007–2009). Variables collected included demographic and risk factors, high-sensitivity C-reactive protein, body composition via dual-energy x-ray absorptiometry, coronary artery calcium by computed tomography, and cardiac dimensions and function by cardiac MRI. Linear regression was used to identify associations of these factors with each biomarker at baseline and with changes in biomarkers over follow-up. Results: NT-proBNP and hs-cTnT were poorly correlated at baseline (Spearman rho 0.083, p = 0.015), with only moderate correlation between change values (rho 0.18, p < 0.001). hs-cTnT positively associated and NT-proBNP inversely associated with male gender and black race. At baseline, both NT-proBNP and hs-cTnT associated with left ventricular end-diastolic volume and wall thickness, but only NT-proBNP associated with left atrial size. Changes in cardiac dimensions between phases were more strongly associated with changes in NT-proBNP than hs-cTnT. NT-proBNP was more strongly associated with high-sensitivity C-reactive protein and measures of body composition than hs-cTnT. Conclusion: Among individuals without CVD in the general population, NT-proBNP and hs-cTnT are nonredundant biomarkers that are differentially associated with demographic and cardiac factors. These findings indicate that hs-cTnT and NT-proBNP may reflect different pathophysiological pathways.

Objective: The aim of this study was to determine the independent value of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein to predict onset of cardiopulmonary disease in a large, multi-center systemic sclerosis cohort followed prospectively. Methods: Subjects from the Canadian Scleroderma Research Group registry with data on N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were identified. Outcomes of interest were death, systolic dysfunction (left ventricular ejection fraction < 50% or medications for heart failure), pulmonary arterial hypertension by right heart catheterization, pulmonary hypertension by cardiac echocardiography (systolic pulmonary artery pressures ⩾ 45 mmHg), arrhythmias (pacemaker/implantable cardiac defibrillator or anti-arrhythmic medications), and interstitial lung disease. Multivariate Cox proportional hazard models were generated for each outcome. Results: A total of 675 subjects were included with a mean follow-up of 3.0 ± 1.8 years. Subjects were predominantly women (88.4%) with mean age of 58.2 ± 11.3 years and mean disease duration of 13.7 ± 9.1 years. One hundred and one (101, 15%) subjects died during follow-up, 37 (6.4 %) developed systolic dysfunction, 18 (2.9%) arrhythmias, 34 (5.1%) pulmonary arterial hypertension, 43 (7.3%) pulmonary hypertension, and 48 (12.3%) interstitial lung disease. In multivariate analyses, elevated levels of N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein were associated with increased risk of death, while elevated levels of N-terminal pro b-type natriuretic peptide and C-reactive protein were associated with increased risk of developing pulmonary hypertension. Conclusion: In systemic sclerosis, N-terminal pro b-type natriuretic peptide, high-sensitivity cardiac troponin T, and C-reactive protein have independent predictive value for death and pulmonary hypertension. A larger study would be required to determine the predictive value of these biomarkers for less common systemic sclerosis outcomes.

Abstract Background: Data are sparse regarding the association between C-reactive protein (CRP) and percutaneous coronary intervention (PCI) in long-term prognosis. Previous studies have shown that PCI evokes an inflammatory response. We tested the hypothesis that the CRP response to PCI has a prognostic value. Methods: We investigated 891 consecutive patients presenting with stable or unstable angina pectoris, with serum concentrations of cardiac troponin T ≤0.03 μg/L, who were undergoing a variety of PCIs. Serum concentrations of CRP and cardiac troponin T were determined before and the day after PCI. The mean follow-up time after PCI was 2.6 years, and the endpoint was death or nonfatal myocardial infarction. Results: Seventy-six patients reached the endpoint (4.6% death, 3.9% nonfatal myocardial infarction), whereas 21% developed myocardial infarction during the procedure. CRP increased more than 2-fold after the procedure. Patients in the third tertile of the CRP response to PCI had an increased risk for death or nonfatal myocardial infarction in multivariate analysis. Conclusions: Increased serum CRP in response to PCI is an independent predictor of death or nonfatal myocardial infarction independent of myocardial injury during the procedure. CRP determinations might be of value in risk stratification after PCI.

Introduction: Cardiac troponin T in renal failure is used for the assessment of cardiovascular risk and mortality. Elevated cardiac troponin T levels correlate with subclinical myocardial necrosis, coronary heart disease, several echocardiographic parameters, metastatic calcification, as well as the presence of diabetes and uremic toxins. Aim: The aim of the authors was to examine the impact of factors, mainly the independent effects of inflammatory laboratory parameters, which may influence hypersensitive troponin T levels in hemodialysed patient groups with and without diabetes. Method: Hemodialysed patient groups with (n = 44) and without diabetes (n = 76) were studied. Difference in serum hypersensitive troponin T values before and after dialysis were analysed by paired Wilcoxon test. Factors possibly affecting the level of hypersensitive troponin T (especially inflammatory markers) were evaluated by multiregression analysis. Results: Hypersensitive troponin T levels in patients without diabetes (p = 0.0003) and those with diabetes (p = 0.0032) significantly increased during hemodialysis. In patients without diabetes several factors had significant effect on hypersensitive troponin T including age (p = 0.025), duration of hemodialysis (p = 0.0002), presence of cardiovascular complications (p = 0.0002), high sensivivity C-reactive protein (p = 0.0021), white blood cell count (p = 0.038), and the monocyte ratio (p = 0.0202). However, in patients with diabetes only high sensivivity C-reactive protein (p = 0.0024) showed association with hypersensitive troponin T levels. Conclusions: In hemodyalised patients with and without diabetes the hypersensitive troponin T levels are differently influenced by clinical and inflammatory laboratory parameters, which should be taken into consideration during clinical judgement.
