Background: Patients with chronic kidney disease are at increased risk for cardiovascular morbidity and mortality. We assessed the association between albuminuria and death or cardiovascular events among patients with stable coronary disease. Methods: We studied patients enrolled in the Prevention of Events with an ACE Inhibitor (PEACE) trial, in which patients with chronic stable coronary disease and preserved systolic function were randomized to trandolapril or placebo and followed for a median of 4.8 years. The urinary albumin to creatinine ratio (ACR) assessed in a core laboratory in 2977 patients at baseline and in 1339 patients at follow-up (mean 34 months) was related to estimated glomerular filtration rate (eGFR) and outcomes. Results: The majority of patients (73%) had a baseline albumin/creatinine ratio within the normal range. Independent of the eGFR and other baseline covariates, a higher albumin/creatinine ratio even within the normal range was associated with increased risks for all-cause mortality (p < 0.001) and cardiovascular death (p = 0.01). The effect of trandolapril therapy on outcomes was not significantly modified by the level of albuminuria. Nevertheless, trandolapril therapy was associated with a significantly lower mean follow-up ACR (12.5 ug/mg vs 14.6 ug/mg, p = 0.0002), after adjusting for baseline ACR, time between collections and other covariates. An increase in ACR over time was associated with increased risk of cardiovascular death (HR per log ACR 1.74, 95% confidence intervals 1.08–2.82). Conclusions: Albuminuria, even in low levels within the normal range, is an independent predictor of cardiovascular and all-cause mortality.

Abstract ObjectiveDiabetes prevalence in Greenland is high and increasing. The aim of this study was to examine the effect of diabetes and the diabetogenic TBC1D4 variant on kidney function in Greenland in a population-based setting.Research Design and MethodsHealth survey data and TBC1D4 genotypes from 5,336 Greenlanders was used to estimate odds ratios (ORs) of albuminuria (>30 mg/g creatinine) and chronic kidney disease (CKD, eGFR<60 ml/min/1.73m2), comparing individuals with and without diabetes. Using baseline and follow-up data from individuals who participated in two surveys we examined the effect of diabetes on eGFR and urinary albumin creatinine ratio (UACR) at follow-up, stepwise adjusting for baseline confounders including the TBC1D4 variant.ResultsA total of 9.3% had diabetes of the 3,909 participants with complete data. Albuminuria and CKD was found in 27.6% and 9.5% among those with and without diabetes respectively. Diabetes was associated with increased risk of albuminuria (OR(95% CI) = 2.37 (1.69,3.33) p<0.001) and the TBC1D4 variant protected against albuminuria (OR(95% CI) = 0.44 (0.22,0.90) p=0.02) in a multivariable model. Neither diabetes nor the TBC1D4 variant significantly associated with CKD. Diabetes was not associated with changes in eGFR or UACR over a median of 11.3 years.ConclusionDiabetes conferred increased risk of albuminuria and the TBC1D4 variant was associated with decreased risk of albuminuria, but neither were associated with CKD. The presence/absence of diabetes did not predict changes in eGFR and UACR in longitudinal analyses. The potential renoprotective association of the TBC1D4 variant on albuminuria calls for further studies.

Abstract Background and Aims Chronic and end-stage kidney disease patients experience significantly increased risk of cardiovascular morbidity and mortality due to multitude of interlinked pathophysiological processes inducing metabolic and inflammatory conditions. Pulse pressure (PP) reports cardiac and vascular conditions, where consistently high PP values are associated with atrial fibrillation, aortic insufficiency, arterial stiffness or arteriovenous malformation, and low PP values may be associated with aortic valve stenosis, cardiac insufficiency or cardiac tamponade. However, the association of pre-hemodialysis (pre-HD) PP with mortality among hemodialysis patients is not well understood. In this study, we aim to explore the extent to which PP is associated with mortality. Method We analyzed pre-HD PP (calculated as pre-HD SBP minus pre-HD DBP) between 1/2001 and 12/2012 in hemodialysis patients treated in U.S. Fresenius Medical Care facilities. A 3-months baseline period was defined as months 4 to 6 after hemodialysis initiation, all-cause mortality was noted during follow-up. Only patients who survived baseline were included. Censoring events were renal transplantation, modality change, or study end. We built Cox proportional hazards models with spline terms, allowing us to model nonlinear effects of pre-HD PP as a continuous variable and its relationship with all-cause mortality. Results We included 152,625 patients. Mean age was 60.8 years, 59% were white and 56% were male. During a median follow-up of 26.0 months 40.4% patients died. We found that for patients with pre-HD PP between 49.2 mmHg and 74.7 mmHg, were associated with better survival. In contrast, a PP below 49.2 mmHg and above 74.7 mmHg were associated with higher mortality. Similar nonlinear effects are seen in SBP for a given pre-HD PP value (see Fig. 1). Conclusion The association of pre-HD PP with mortality is nonlinear, and a better understanding of the nonlinearity will provide further insights into disentangling the associated mediators affecting its dynamics. Our findings may aid risk stratification in HD patients.

Abstract Background In patients with diabetes and hypertension, proteinuria is independently associated with all-cause death. However, in the general population, urinary albumin to creatinine ratio (UACR) is less used to predict all-cause mortality. When the urinary albumin to creatinine ratio is within the normal range (UACR< 30 mg/g), the clinical relevance of an increased urinary albumin excretion rate is still debated. We studied the relationship between UACR and all-cause mortality in community populations, and compared UACR groups within the normal range. Methods The participants were the inhabitants from the Wanshoulu community in Beijing, China. The average age is 71.48 years, and the proportion of women is 60.1%. A total of 2148 people completed random urine samples to determine the urinary albumin to creatinine ratio (UACR). The subjects were divided into three groups according to UACR: Group 1 (UACR< 10 mg/g), Group 2 (10 mg/g < UACR< 30 mg/g), Group 3 (UACR> 30 mg/g). We used Kaplan-Meier survival analysis and Cox regression model to verify the relationship between UACR and all-cause mortality. Results At an average follow-up of 9.87 years (718,407.3 years), the total mortality rate were 183.4/1000. In the Cox proportional hazards model, after adjusting for possible confounders, those with normal high-value UACR (group 2) showed a higher all-cause mortality than those with normal low-value UACR (group 1) [hazard ratio (HR) 1.289, 95% confidence interval (CI) 1.002 ~ 1.659 for all-cause mortality]. Those with proteinuria (group 3) showed a higher all-cause mortality than those with normal low-value UACR (group 1) [hazard ratio (HR) 1.394, 95% confidence interval (CI) 1.020 ~ 1.905 for all-cause mortality]. Conclusion Urinary albumin to creatinine ratio is an important risk factor for all-cause death in community population. Even if it is within the normal range (UACR< 30 mg/g), it occurs in people with high normal value (10 mg/g < UACR< 30 mg/g), the risk of all-cause death will also increase.

Abstract Objective It is unclear whether relatively low glycated haemoglobin (HbA1c) levels are beneficial or harmful for the long-term health outcomes among people without diabetes. We aimed to investigate the association between low HbA1c levels and mortality among the US general population. Methods This study includes a nationally representative sample of 39 453 US adults from the National Health and Nutrition Examination Surveys 1999–2014, linked to mortality data through 2015. We employed the parametric g-formula with pooled logistic regression models and the ensemble machine learning algorithms to estimate the time-varying risk of all-cause and cardiovascular mortality by HbA1c categories (low, 4.0 to &lt;5.0%; mid-level, 5.0 to &lt;5.7%; prediabetes, 5.7 to &lt;6.5%; and diabetes, ≥6.5% or taking antidiabetic medication), adjusting for 72 potential confounders including demographic characteristics, lifestyle, biomarkers, comorbidities and medications. Results Over a median follow-up of 7.5 years, 5118 (13%) all-cause deaths, and 1116 (3%) cardiovascular deaths were observed. Logistic regression models and machine learning algorithms showed nearly identical predictive performance of death and risk estimates. Compared with mid-level HbA1c, low HbA1c was associated with a 30% (95% CI, 16 to 48) and a 12% (95% CI, 3 to 22) increased risk of all-cause mortality at 5 years and 10 years of follow-up, respectively. We found no evidence that low HbA1c levels were associated with cardiovascular mortality risk. The diabetes group, but not the prediabetes group, also showed an increased risk of all-cause mortality. Conclusions Using the US national database and adjusting for an extensive set of potential confounders with flexible modelling, we found that adults with low HbA1c were at increased risk of all-cause mortality. Further evaluation and careful monitoring of low HbA1c levels need to be considered.

Abstract Objective: The aim of this meta-analysis was to investigate the association between malnutrition assessed by the controlling nutritional status (CONUT) score and all-cause mortality in patients with heart failure. Design: Systematic review and meta-analysis. Settings: A comprehensively literature search of PubMed and Embase databases was performed until 30 November 2020. Studies reporting the utility of CONUT score in prediction of all-cause mortality among patients with heart failure were eligible. Patients with a CONUT score ≥2 are grouped as malnourished. Predictive values of the CONUT score were summarized by pooling the multivariable-adjusted risk ratios (RR) with 95 % CI for the malnourished v. normal nutritional status or per point CONUT score increase. Participants: Ten studies involving 5196 patients with heart failure. Results: Malnourished patients with heart failure conferred a higher risk of all-cause mortality (RR 1·92; 95 % CI 1·58, 2·34) compared with the normal nutritional status. Subgroup analysis showed the malnourished patients with heart failure had an increased risk of in-hospital mortality (RR 1·78; 95 % CI 1·29, 2·46) and follow-up mortality (RR 2·01; 95 % CI 1·58, 2·57). Moreover, per point increase in CONUT score significantly increased 16% risk of all-cause mortality during the follow-up. Conclusions: Malnutrition defined by the CONUT score is an independent predictor of all-cause mortality in patients with heart failure. Assessment of nutritional status using CONUT score would be helpful for improving risk stratification of heart failure.

Background: In patients with atrial fibrillation (AF), the long-term prognosis of long electrocardiographic pauses in the ventricular action is not well-studied. Methods: Consecutive Holter recordings in patients with AF (n=200) between 2009-2011 were evaluated, focusing on pauses of at least 2.5 s. Outcomes of interest were all-cause mortality and pacemaker implantation. Results: Forty-three patients (21.5%) had pauses with a mean of 3.2 s and SD of 0.9 s. After a median follow-up of 99 months (ranging 89-111), 47% (20/43) of the patients with, and 45% (70/157) without pauses were deceased. Pauses of ≥ 2.5 s did not constitute a risk of increased mortality: HR = 0.75; (95% CI: 0.34 - 1.66); p = 0.48. Neither did pauses of ≥ 3.0 s: HR = 0.43; (95% CI: 0.06 - 3.20); p = 0.41. Sixteen percent of patients with pauses underwent pacemaker implantation during follow-up. Only pauses in patients referred to Holter due to syncope and/or dizzy spells were associated with an increased risk of pacemaker treatment: HR = 4.7 (95% CI: 1.4-15.9), p = 0.014, adjusted for age, sex and rate-limiting medication. Conclusion: In patients with AF, prolonged electrocardiographic pauses of ≥ 2.5 s or ≥ 3.0 s are not a marker for increased mortality in this real-life clinical study.

Objective Several studies have shown an increased risk for cardiovascular disease (CVD) in hyperthyroidism, but most studies have been too small to address the effect of hyperthyroidism on individual cardiovascular endpoints. Our main aim was to assess the association among hyperthyroidism, acute cardiovascular events and mortality. Design It is a nationwide population-based cohort study. Data were obtained from the Danish Civil Registration System and the Danish National Patient Registry, which covers all Danish hospitals. We compared the rate of all-cause mortality as well as venous thromboembolism (VTE), acute myocardial infarction (AMI), ischemic and non-ischemic stroke, arterial embolism, atrial fibrillation (AF) and percutaneous coronary intervention (PCI) in the two cohorts. Hazard ratios (HR) with 95% confidence intervals (95% CI) were estimated. Results The study included 85 856 hyperthyroid patients and 847 057 matched population-based controls. Mean follow-up time was 9.2 years. The HR for mortality was highest in the first 3 months after diagnosis of hyperthyroidism: 4.62, 95% CI: 4.40–4.85, and remained elevated during long-term follow-up (>3 years) (HR: 1.35, 95% CI: 1.33–1.37). The risk for all examined cardiovascular events was increased, with the highest risk in the first 3 months after hyperthyroidism diagnosis. The 3-month post-diagnosis risk was highest for atrial fibrillation (HR: 7.32, 95% CI: 6.58–8.14) and arterial embolism (HR: 6.08, 95% CI: 4.30–8.61), but the risks of VTE, AMI, ischemic and non-ischemic stroke and PCI were increased also 2- to 3-fold. Conclusions We found an increased risk for all-cause mortality and acute cardiovascular events in patients with hyperthyroidism.

Abstract Background Identifying people with HIV (PWH) at risk for chronic kidney disease, cardiovascular events, and death is crucial. We evaluated biomarkers to predict all-cause mortality and cardiovascular events, and measured glomerular filtration rate (mGFR) slope. Methods Biomarkers were measured at enrollment. Baseline and 5-year mGFR were measured by plasma iohexol clearance. Outcomes were a composite criterion of all-cause mortality and/or cardiovascular events, and mGFR slope. Results Of 168 subjects, 146 (87.4%) had undetectable HIV load. Median follow-up was 59.1 months (interquartile range, 56.2–62.1). At baseline, mean age was 49.5 years (± 9.8) and mean mGFR 98.9 mL/min/1.73m2 (± 20.6). Seventeen deaths and 10 cardiovascular events occurred during 5-year follow-up. Baseline mGFR was not associated with mortality/cardiovascular events. In multivariable analysis, cystatin C (hazard ratio [HR], 5.978; 95% confidence interval [CI], 2.774–12.88; P &lt; .0001) and urine albumin to creatinine ratio (uACR) at inclusion (HR, 1.002; 95% CI, 1.001–1.004; P &lt; .001) were associated with mortality/cardiovascular events. Area under receiver operating curve of cystatin C was 0.67 (95% CI, .55–.79) for mortality/cardiovascular event prediction. Biomarkers were not associated with GFR slope. Conclusions uACR and cystatin C predict all-cause mortality and/or cardiovascular events in PWH independently of mGFR.

To investigate the association of body weight variability (BWV) with adverse cardiovascular (CV) outcomes in patient with pre-dialysis chronic kidney disease (CKD), a total of 1867 participants with pre-dialysis CKD from Korean Cohort Study for Outcomes in Patients With Chronic Kidney Disease (KNOW-CKD) were analyzed. BWV was defined as the average absolute difference between successive values. The primary outcome was a composite of non-fatal CV events and all-cause mortality. Secondary outcomes were fatal and non-fatal CV events and all-cause mortality. High BWV was associated with increased risk of the composite outcome (adjusted hazard ratio (HR) 1.745, 95% confidence interval (CI) 1.065 to 2.847) as well as fatal and non-fatal CV events (adjusted HR 1.845, 95% CI 1.136 to 2.996) and all-cause mortality (adjusted HR 1.861, 95% CI 1.101 to 3.145). High BWV was associated with increased risk of fatal and non-fatal CV events, even in subjects without significant body weight gain or loss during follow-up periods (adjusted HR 2.755, 95% CI 1.114 to 6.813). In conclusion, high BWV is associated with adverse CV outcomes in patients with pre-dialysis CKD.

Background: Microalbuminuria (MA) is associated with an increased risk of cardiovascular disease (CVD) but the mechanism by which microalbuminuria imparts this increased risk is not known. In this study we assessed the relationship between MA and the development and progression of atherosclerosis by measuring the incidence of new CAC and the progression of existing CAC in individuals free of clinical CVD. Methods : The Multi-Ethnic Study of Atherosclerosis (MESA) is a prospective cohort study of 6,814 participants free of clinical CVD at entry who underwent assessment of coronary artery calcification (CAC) by computerized tomography at baseline. Overall, 6,775 individuals had data available on urinary albumin creatinine ratio (UACR); 1,109 individuals were excluded for missing data or macroalbuminuria (UACR≥300 mg/g). Incident CAC was defined as detectable CAC at follow-up among those with CAC=0 at baseline, and absolute CAC score change among those with CAC>0 at baseline. Relative risk (RR) regression adjusted for covariates; and multivariable adjusted median regression was employed to assess the independent relationship of MA with CAC incidence and progression. Results : Of the 5,666 subjects (mean age 62±10 years, 48% males), baseline MA was seen in 424 (7%) participants, who were more likely to have CAC compared to those with normal UACR (62% vs. 48%, p<0.0001). During a mean follow-up of 2.4±0.8 years, those with MA were more likely to develop CAC (28% vs. 15%, p<0.0001) and they had a higher absolute median increase in CAC (47 vs. 29 Agatston Units, p<0.0001). After adjustment for age, gender, ethnicity, site, follow-up duration, diabetes, hypertension, smoking, family history of heart attack, total cholesterol, lipid lowering medications and body mass index; MA was associated with incident CAC (RR 1.65; 95%CI 1.41–2.48) among those with CAC=0 at baseline. Among those with CAC>0 at baseline, MA was associated with a median increase in CAC of 7.93 (95%CI 0.38 –15.47) Agatston Units in multivariable adjusted analyses (variables noted above). Conclusion : MA is independently associated with development of incident CAC and progression of CAC in an asymptomatic multi-ethnic population, and may in part explain its associated increased risk of CVD.
