  • 简介:AbstractBackground:The diagnosis of contrast-induced nephropathy (CIN) is usually based on changes in serum creatinine (sCr). However, sCr has poor sensitivity as a biomarker of kidney injury. The aim of this study was to investigate the usefulness of serum cystatin C (sCysC) to predict CIN after intra-arterial interventions.Methods:A total of 360 consecutive patients underwent intra-arterial procedures using digital subtraction angiography. SCr, sCysC, and estimated glomerular filtration rate were measured at 1 to 2 days before and at 48, 72 h, and 7 days after the procedure.Results:Thirty-one patients (8.61%) developed CIN. Receiver operating characteristic (ROC) curve analysis showed that preoperative sCysC levels had good discriminatory power (area under the curve [AUC] = 0.634; 95% confidence interval [CI] = 0.526-0.743) for evaluating the risk of CIN after an endovascular procedure, with a sensitivity of 53.33% and specificity of 73.70%. ROC analysis showed that sCysC at 48 h after contrast medium administration was predictive of CIN after an endovascular procedure (AUC = 0.735; 95% CI = 0.647-0.822) with satisfactory sensitivity of 74.20% and specificity of 63.90%. Diabetes mellitus was an independent risk factor for CIN (odds ratio = 2.778; 95% CI = 1.045-7.382; P = 0.040).Conclusions:SCysC is an appropriate biomarker to predict the occurrence of CIN. Baseline sCysC before an intervention is useful to obtain a preliminary estimate of the risk of CIN. A 48-h cut-off value of sCysC of 0.99 mg/L after an endovascular procedure may help to rule out patients at lower risk of CIN.

  • 简介:AbstractBackground:Hypertension is associated with stroke-related mortality. However, the long-term association of blood pressure (BP) and the risk of stroke-related mortality and the influence path of BP on stroke-related death remain unknown. The current study aimed to estimate the long-term causal associations between BP and stroke-related mortality and the potential mediating and moderated mediating model of the associations.Methods:This is a 45-year follow-up cohort study and a total of 1696 subjects were enrolled in 1976 and 1081 participants died by the latest follow-up in 2020. COX proportional hazard model was used to explore the associations of stroke-related death with baseline systolic blood pressure (SBP)/diastolic blood pressure (DBP) categories and BP changes from 1976 to 1994. The mediating and moderated mediating effects were performed to detect the possible influencing path from BP to stroke-related deaths. E value was calculated in the sensitivity analysis.Results:Among 1696 participants, the average age was 44.38 ± 6.10 years, and 1124 were men (66.3%). After a 45-year follow-up, a total of 201 (11.9%) stroke-related deaths occurred. After the adjustment, the COX proportional hazard model showed that among the participants with SBP ≥ 160 mmHg or DBP ≥ 100 mmHg in 1976, the risk of stroke-related death increased by 217.5% (hazard ratio [HR] = 3.175, 95% confidence interval [CI]: 2.297-4.388), and the adjusted HRs were higher in male participants. Among the participants with hypertension in 1976 and 1994, the risk of stroke-related death increased by 110.4% (HR= 2.104, 95% CI: 1.632-2.713), and the adjusted HRs of the BP changes were higher in male participants. Body mass index (BMI) significantly mediated the association of SBP and stroke-related deaths and this mediating effect was moderated by gender.Conclusions:In a 45-year follow-up, high BP and persistent hypertension are associated with stroke-related death, and these associations were even more pronounced in male participants. The paths of association are mediated by BMI and moderated by gender.
