Abstract Introduction Cardiovascular disease is the leading cause of death in patients with end-stage renal disease on haemodialysis. Guidelines recommend echocardiography in all incident patients on dialysis and every three years, or when considered for kidney transplantation. The prognostic value of significant valve disease or reduced systolic function detected by echocardiographic screening is however not clear. Purpose We aimed to test the hypothesis that structural heart disease in an unselected, contemporary population of patients on maintenance dialysis is associated to a higher risk of death. Methods Adult chronic haemodialysis patients in two large dialysis centers had transthoracic echocardiography performed immediately prior to dialysis and were followed prospectively. Significant structural or functional left sided heart disease was defined as moderate or severe left-sided valve disease or left ventricular ejection fraction (LVEF) ≤40%. Results Among the 247 included patients (66 [IQR 64–67] years of age, 68% male), 54 (22%) had significant structural or functional left sided heart disease. An LVEF ≤40% was observed in 31 patients (13%). Severe or moderate aortic stenosis was present in 4 (2%) and 16 (7%) patients respectively, moderate mitral regurgitation in 4 (2%) patients and mitral stenosis in one (0.4%) patient. In more than half of the patients (56%), significant structural or functional left sided heart disease was not recognized prior to the study. After 2.8 years of follow-up, all-cause mortality was 52% for patients with significant heart disease and 32% for patients without significant structural heart disease (hazard ratio [HR] 1.95 (95% CI 1.25–3.06) (Figure). On multivariable adjusted Cox proportional hazard analysis, including age, sex, ischemic heart disease, diabetes, hypertension and time on dialysis, structural heart disease was an independent predictor of mortality with a HR of 1.60 (95% CI 1.01–2.55) along with age (HR per year 1.05 [95% CI 1.03–1.07]). Kaplan-Meier estimate of survival Conclusion Left ventricular systolic dysfunction and moderate to severe valve disease are common and often unrecognized in patients with end-stage renal failure on haemodialysis and are associated with a higher risk of death.

A 54-year-old man with remote large cell non-Hodgkin’s lymphoma in remission following R-CHOP and severe atopic dermatitis was transferred from another hospital with a non-ST elevation myocardial infarction. Over the preceding year, the patient had suffered recurrent admissions for acutely decompensated heart failure with a newly depressed left ventricular ejection fraction (LVEF) of 20% by echocardiography and rapidly progressive end-stage renal disease of unclear etiology requiring the initiation of hemodialysis. Prior workup had demonstrated an infrarenal abdominal aortic aneurysm and bilateral common iliac artery aneurysms with subsequent computed tomography (CT) additionally demonstrating a superior mesenteric artery aneurysm. The patient was taken for immediate coronary arteriography, which demonstrated giant aneurysms in the left main and right coronary arteries, as well as multivessel severe stenoses. CT coronary angiogram demonstrated significant circumferential wall thickening throughout the coronary vasculature. Given concern for IgG4-related disease (IgG4-RD), a renal biopsy was pursued that confirmed the diagnosis. 18F-fluorodeoxyglucose positron emission tomography-CT identified only mild aortic inflammation. The patient was treated with high-dose steroids and rituximab. The serological inflammatory markers improved, and he underwent coronary artery bypass grafting. Pericardial, aortic adventitial, left internal mammary artery, and saphenous vein biopsies showed cardiovascular involvement of IgG4-RD. The patient has been maintained on rituximab with normalization of his LVEF and no recurrence of chest pain over the past eighteen months. IgG4-RD is a fibroinflammatory systemic disease newly described in 2003 and only recently found to involve the cardiovascular system with several reports of peripheral aneurysmal disease. To our knowledge, the current case represents the first report of a patient successfully treated for biopsy-proven IgG4-RD associated with coronary artery disease and left ventricular systolic dysfunction. IgG4-RD may represent a novel mechanism underlying some forms of peripheral and coronary arterial disease and may offer new insights into vascular biology.

Rationale: End-stage renal disease (ESRD) patients have high annual mortality mainly due to cardiovascular causes. The acute effects of obstructive and central sleep apnea on cardiac function in ESRD patients have not been determined. We therefore tested, in patients with ESRD, the hypotheses that (1) sleep apnea induces deterioration in cardiac function overnight and (2) attenuation of sleep apnea severity by ultrafiltration (UF) attenuates this deterioration. Methods: At baseline, ESRD patients, on conventional hemodialysis, with left ventricular ejection fraction (LVEF) >45% had polysomnography (PSG) performed on a non-dialysis day to determine the apnea-hypopnea index (AHI). Echocardiography was performed at the bedside, before and after sleep. Isovolumetric contraction time divided by left ventricular ejection time (IVCT/ET) and isovolumetric relaxation time divided by ET (IVRT/ET) were measured by tissue doppler imaging. The myocardial performance index (MPI), a composite of systolic and diastolic function was also calculated. One week later, subjects with sleep apnea (AHI ≥15) had fluid removed by UF, followed by repeat PSG and echocardiography. ­Results: Fifteen subjects had baseline measurements, of which 7 had an AHI <15 (no–sleep-apnea group) and 8 had an AHI ≥15 (sleep-apnea group). At baseline, there was no overnight change in the LVEF in either the no-sleep-apnea group or the sleep-apnea group. In the no-sleep-apnea group, there was also no overnight change in MPI, IVCT/ET and IVRT/ET. However, in the sleep-apnea group there were overnight increases in MPI, IVCT/ET and IVRT/ET (p = 0.008, 0.007 and 0.031, respectively), indicating deterioration in systolic and diastolic function. Following fluid removal by UF in the sleep-apnea group, the AHI decreased by 48.7% (p = 0.012) and overnight increases in MPI, IVCT/ET and IVRT/ET observed at baseline were abolished. Conclusions: In ESRD, cardiac function deteriorates overnight in those with sleep apnea, but not in those without sleep apnea. This overnight deterioration in the sleep-apnea group may be at least partially due to sleep apnea, since attenuation of sleep apnea by UF was accompanied by elimination of this deleterious overnight effect.

Abstract Background Cardiovascular disease is the most common cause of death in patients with end-stage kidney disease on haemodialysis. The potential clinical consequence of systematic echocardiographic assessment is however not clear. In an unselected, contemporary population of patients on maintenance haemodialysis we aimed to assess: the prevalence of structural and functional heart disease, the potential therapeutic consequences of echocardiographic screening and whether left-sided heart disease is associated with prognosis. Methods Adult chronic haemodialysis patients in two large dialysis centres had transthoracic echocardiography performed prior to dialysis and were followed prospectively. Significant left-sided heart disease was defined as moderate or severe left-sided valve disease or left ventricular ejection fraction (LVEF) ≤40%. Results Among the 247 included patients (mean 66 years of age [95%CI 64–67], 68% male), 54 (22%) had significant left-sided heart disease. An LVEF ≤40% was observed in 31 patients (13%) and severe or moderate valve disease in 27 (11%) patients. The findings were not previously recognized in more than half of the patients (56%) prior to the study. Diagnosis had a potential impact on management in 31 (13%) patients including for 18 (7%) who would benefit from initiation of evidence-based heart failure therapy. After 2.8 years of follow-up, all-cause mortality among patients with and without left-sided heart disease was 52 and 32% respectively (hazard ratio [HR] 1.95 (95%CI 1.25–3.06). A multivariable adjusted Cox proportional hazard analysis showed that left-sided heart disease was an independent predictor of mortality with a HR of 1.60 (95%CI 1.01–2.55) along with age (HR per year 1.05 [95%CI 1.03–1.07]). Conclusion Left ventricular systolic dysfunction and moderate to severe valve disease are common and often unrecognized in patients with end-stage kidney failure on haemodialysis and are associated with a higher risk of death. For more than 10% of the included patients, systematic echocardiographic assessment had a potential clinical consequence.

Objective: To determine the risk for major adverse cardiovascular events (MACE) following acute coronary syndrome (ACS) in patients with and without heart failure (HF) and whether this risk varies by race and comorbidity. Methods: We studied adults with and without HF who underwent percutaneous coronary intervention (PCI) for the treatment of ACS in the Pharmacogenomic Resource to improve Medication Effectiveness Genotype Guided Antiplatelet Therapy study. ACS was defined by the presence of ≥2 of the following: ischemic symptoms, acutely elevated cardiac troponin, or ischemic electrocardiographic changes. HF was defined prior to PCI as a known history of HF, left ventricular ejection fraction <50%, or brain natriuretic peptide level >400 pg/mL. Demographic and clinical characteristics were collected prior to PCI. Race was self-reported. Participants were followed for up to 1 year for MACE. We constructed Cox proportional hazard models, adjusted for demographic and clinical characteristics, separately in those with and without HF to identify independent predictors of MACE. Results: Since 2014, 1,230 individuals have undergone PCI for ACS. Those with HF (n=419) were older and had more comorbidities than those without HF (n=811). The incidence of MACE per 100 person years was 40.4 in those with HF and 22.2 in those without HF (p<0.001). African American race was associated with increased risk for MACE following ACS in those without but not with a history of HF. Other clinical factors associated with MACE following ACS were older age and end stage renal disease in those with HF and diabetes, end stage renal disease, and peripheral arterial disease in those without HF (Table). Conclusions: Individuals with HF are at increased risk of MACE following ACS irrespective of race. However, in those without HF, African Americans have a higher risk of MACE following ACS relative to their white counterparts. Individuals with end stage renal disease are at high risk of MACE following ACS regardless of HF status.

Introduction: Echocardiography is a simple and established method of evaluating cardiac functions, assessing left ventricle geometry, and systolic and diastolic functions. Patients with chronic kidney disease have a tremendous burden of cardiovascular disease (CVD), and patients with end-stage renal disease (ESRD) are at a greater risk of CVD and deaths.Materials and Methods: In this study, 245 incident dialysis patients were included, and none of the patient was on erythropoietin. All the patients were aged >18 years. Patients with ESRD, already on maintenance dialysis, were not included in this study. Patient’s data such as demographic details, comorbidities, laboratory values, echocardiographic changes, management, and outcome were recorded.Results: Out of 245 patients, 165 (67.3%) were males and 80 (32.6%) females. The mean age of the patients was 49.7 years. Left ventricular hypertrophy (LVH) was observed in 188 (76.7%), mild left ventricular dysfunction (LVD) in 25.7%, moderate LVD in 23.67%, severe LVD in 8.5%, global hypokinesia in 33.8%, valvular heart disease in 26.5%, regional wall motion abnormality in 4.4%, and pericardial effusion in 1.6% patients. Echocardiographic changes, such as LVD, LVH, and global hypokinesia, were observed in greater number in hypertensive group com-pared to normotensive group (P < 0.05). On regression analysis adjusted for age and gender, we found that hypertension and anemia (<10 g/dL) were associated with LVH. Further, hypertension and anemia (Hb < 10 g/dL) were associated with LVD. Similarly, anemia (Hb < 10 g/dL) was associated with global hypokinesia and valvular heart disease. LVD was associated with death in our study.Conclusion: Echocardiography is a noninvasive diagnostic test which detects early changes in cardiac parameters. All ESRD patients with hypertension and anemia at the time of initiation of renal replacement therapy must undergo echocardiography screening.

Objectives Dental problems occur widely in patients with chronic kidney disease (CKD) and may increase comorbidities. Root canal therapy (RCT) is a common procedure for advanced decayed caries with pulp inflammation and root canals. However, end-stage renal disease (ESRD) patients are considered to have a higher risk of potentially life-threatening infections after treatment and might fail to receive satisfactory dental care such as RCT. We investigated whether appropriate intervention for dental problems had a potential impact among dialysis patients. Design Men and women who began maintenance dialysis (hemodialysis or peritoneal dialysis) between January 1, 2000, and December 31, 2015, in Taiwan (total 12,454 patients) were enrolled in this study. Participants were followed up from the first reported dialysis date to the date of death or end of dialysis by December 31, 2015. Setting Data collection was conducted in Taiwan. Results A total of 2633 and 9821 patients were classified into the RCT and non-RCT groups, respectively. From the data of Taiwan’s National Health Insurance, a total of 5,092,734 teeth received RCT from 2000 to 2015. Then, a total of 12,454 patients were followed within the 16 years, and 4030 patients passed away. The results showed that members of the non-RCT group (34.93%) had a higher mortality rate than those of the RCT group (22.79%; p = 0.001). The multivariate-adjusted hazard ratio for the risk of death was 0.69 (RCT vs. non-RCT; p = 0.001). Conclusions This study suggested that patients who had received RCT had a relatively lower risk of death among dialysis patients. Infectious diseases had a significant role in mortality among dialysis patients with non-RCT. Appropriate interventions for dental problems may increase survival among dialysis patients.

Abstract Background Coronary microvascular dysfunction (CMD) is common in end-stage renal disease (ESRD) and is an adverse prognostic marker. Coronary flow velocity reserve (CFVR) is a measure of coronary microvascular function and can be assessed using Doppler echocardiography. Reduced CFVR in ESRD has been attributed to factors such as diabetes, hypertension and left ventricular hypertrophy. The contributory role of other mediators important in the development of cardiovascular disease in ESRD has not been studied. The aim of this study was to examine the prevalence of CMD in a cohort of kidney transplant candidates and to look for associations of CMD with markers of anaemia, bone mineral metabolism and chronic inflammation. Methods Twenty-two kidney transplant candidates with ESRD were studied with myocardial contrast echocardiography, Doppler CFVR assessment and serum multiplex immunoassay analysis. Individuals with diabetes, uncontrolled hypertension or ischaemic heart disease were excluded. Results 7/22 subjects had CMD (defined as CFVR < 2). Demographic, laboratory and echocardiographic parameters and serum biomarkers were similar between subjects with and without CMD. Subjects with CMD had significantly lower haemoglobin than subjects without CMD (102 g/L ± 12 vs. 117 g/L ± 11, p = 0.008). There was a positive correlation between haemoglobin and CFVR (r = 0.7, p = 0.001). Similar results were seen for haematocrit. In regression analyses, haemoglobin was an independent predictor of CFVR (β = 0.041 95% confidence interval 0.012–0.071, p = 0.009) and of CFVR < 2 (odds ratio 0.85 95% confidence interval 0.74–0.98, p = 0.022). Conclusions Among kidney transplant candidates with ESRD, there is a high prevalence of CMD, despite the absence of traditional risk factors. Anaemia may be a potential driver of microvascular dysfunction in this population and requires further investigation.
