Association of maximal stress ergometry performance with troponin T and abdominal aortic calcification score in advanced chronic kidney disease.

ABSTRACT:

Background

Cardiac biomarkers Troponin T (TnT) and N-terminal pro-B-type natriuretic peptide (proBNP) and abdominal aortic calcification score (AAC) are associated with cardiovascular events and mortality in patients with chronic kidney disease (CKD). The effects of cardiac biomarkers and AAC on maximal exercise capacity in CKD are unknown and were studied.

Methods

One hundred seventy-four CKD 4-5 patients not on maintenance dialysis underwent maximal bicycle ergometry stress testing, lateral lumbar radiograph to study AAC, echocardiography and biochemical assessments.

Results

The subjects with proportional maximal ergometry workload (WMAX%) less than 50% of the expected values had higher TnT, proBNP, AAC, left ventricular end-diastolic diameter, left ventricular mass index, E/e' and pulse pressure, and lower global longitudinal strain compared to the better performing patients. TnT (??=?-?0.09, p?=?0.02), AAC (??=?-?1.67, p?ConclusionsTnT and AAC are independently associated with maximal ergometry stress test workload in patients with advanced CKD.

Project description:BackgroundAbdominal aortic calcification (AAC) is prevalent among middle-aged and elderly populations, elevating the risk of cardiovascular and cerebrovascular events. Leveraging data from the National Health and Nutrition Examination Survey (NHANES), we conducted a nationally representative cross-sectional study. Our aim was to evaluate whether subjective interventions could influence AAC scores by modifying the antioxidant/pro-oxidant status of individuals and to investigate the role of glycohemoglobin in this relationship.MethodsThe study analyzed data from 1,600 U.S. adults. The study used oxidation balance score (OBS) as an exposure variable derived from 16 dietary and 4 lifestyle factors, as well as glycohemoglobin obtained from blood tests. The main outcome measure was AAC, which was evaluated by dual-energy X-ray absorption and quantified by Kauppila scoring system.ResultsThe mean (SD) age of the 1,600 patients was 56.53 (10.90) years, with a female predominance (50.22%). According to weighted linear regressions not adjusted for covariates, the AAC scores were lower in the third and fourth quartile groups of OBS than in the first quartile group of OBS (Q3: coefficients [coef], -0.92 [95% CI, -1.64 to-0.20], p = 0.017; Q4: coefficients [coef], -0.97 [95% CI, -1.86 ~ -0.08; p < 0.035]). According to the weighted linear regression subgroup analyses, there were no significant OBS-AAC correlations among males (p > 0.05), but there were significant correlations among females (p < 0.05). Smooth fitting curves showed a more significant trend of change in the negative correlation between OBS and AAC scores in postmenopausal women than in premenopausal women. In further mediation analyses, glycohemoglobin was identified as a mediator of the relationship between the oxidative balance score and AAC.ConclusionThis study revealed a significant negative correlation between OBS and AAC scores, particularly in postmenopausal women. The negative correlation between OBS and AAC is partly mediated by glycohemoglobin.

Project description:BackgroundVascular calcification (VC), especially coronary artery calcification (CAC), serves as a robust predictor of cardiovascular mortality in chronic kidney disease (CKD) patients. Recent studies have revealed that the presence of extra-coronary calcifications (ECCs) contributes to cardiovascular disease (CVD). Elevated myocardial injury markers predict mortality risk in CKD patients and are associated with CVD. Nevertheless, the relationship between VC, including CAC and ECCs, and myocardial injury markers remain unexplored in non-dialysis CKD patients.MethodsIn 278 non-dialysis CKD patients of stage G3 to G5, we assessed calcified scores in CAC (Agatston score) and ECCs including thoracic aortic calcification (TAC), abdominal aortic calcification (AAC), carotid artery calcification, and valvular calcification. We analyzed the relationships between VC and myocardial injury markers of cardiac troponin T (cTnT) and creatine kinase-MB (CK-MB).ResultsA total of 278 non-dialysis CKD patients (median age 52.4 ± 13.2; male 65.1%; diabetes 33.5%) were enrolled. A total of 71.8% (227) of patients had cTnT levels above the upper limit of normal (> 0.014 ng/mL). Moderate to severe (calcified score ≥100 vs. <100), CAC (OR 6.39; 95% CI 1.03-39.61) and TAC (OR 6.16; 95% CI 1.76-21.55) were significantly associated with higher cTnT concentrations after adjustment for confounders. Additionally, male sex and a lower eGFR were also associated with cTnT elevation. However, when we included CAC and TAC in one model, only moderate to severe TAC (OR 4.85; 95% CI 1.38-16.96) was a risk factor for cTnT elevation, but not CAC. Furthermore, patients with severer TAC presented lower diastolic blood pressure (DBP), wider pulse pressure (p < 0.001) and higher prevalence of left ventricular hypertrophy (LVH).ConclusionModerate to severe thoracic aortic calcification (TAC score ≥ 100) is significantly associated with elevated cTnT concentrations in non-dialysis CKD patients of stage G3 to G5. The linkage may result from decreased coronary perfusion and relative myocardial ischemia.
