Abstract Although hyperkalemia is much more common in patients with chronic kidney disease (CKD), the reported frequency of hyperkalemia varies markedly across studies, primarily due to differences in the ascertainment of hyperkalemia and the severity of CKD. Major risk factors for hyperkalemia among CKD patients include lower estimated glomerular filtration rate (eGFR), use of renin–angiotensin–aldosterone system inhibitors (RAASis), diabetes, older age and male gender. The use of two drugs to inhibit RAAS in diabetic CKD markedly increases the risk of hyperkalemia, as demonstrated in large multicenter clinical trials. Hyperkalemia has consistently been associated with an increased risk of adverse events compared with normokalemia, including all-cause mortality and cardiovascular morbidity and mortality. This risk is not explained by differences in comorbidity or estimated GFR, nor concomitant metabolic abnormalities such as acidosis among those with hyperkalemia. Sodium polystyrene sulfonate has been used commonly for decades to treat hyperkalemia in CKD patients, but without any high-quality clinical data to support its efficacy and with an increased risk of rare but serious colonic complications. The newer oral potassium-binding agents, patiromer and sodium zirconium cyclosilicate, have been shown to be effective and safe for the non-emergent treatment of hyperkalemia in CKD patients, including patients treated with RAASis. Although the long-term use of these medications may permit continuation of RAASis in CKD patients with hyperkalemia, the overall impact of this approach (as compared with down-titration of RAASis and/or up-titration of diuretics) on long-term morbidity, mortality and quality of life remains uncertain.

Abstract Background Frailty is associated with reduced quality of life, poor health outcomes, and death. Past studies have investigated how specific biomarkers are associated with frailty but understanding biomarkers in concert with each other and the associated risk of frailty is critical for clinical application. Methods Using a sample aged ≥59 years at baseline from the Swedish AMORIS cohort (n=19341), with biomarkers measured at baseline (1985-1996), we conducted latent class analysis with 18 biomarkers and used Cox models to determine the association between class and frailty and all-cause mortality. Results Four classes were identified. Compared to the largest class, the Reference class (81.7%), all other classes were associated with increased risk of both frailty and mortality. The Anemia class (5.8%), characterized by comparatively lower iron markers and higher inflammatory markers, had HR=1.54, 95% CI 1.38, 1.73 for frailty and HR=1.76, 95% CI 1.65, 1.87 for mortality. The Diabetes class (6.5%) was characterized by higher glucose and fructosamine, and had HR=1.59, 95% CI 1.43, 1.77 for frailty and HR=1.74, 95% CI 1.64, 1.85 for mortality. Finally, the Liver class (6.0%), characterized by higher liver enzyme levels, had HR=1.15, 95% CI 1.01, 1.30 for frailty and HR=1.40, 95% CI 1.31, 1.50 for mortality. Sex-stratified analyses did not show any substantial differences between men and women. Conclusions Distinct sets of commonly available biomarkers were associated with development of frailty and monitoring these biomarkers in patients may allow for earlier detection and possible prevention of frailty, with the potential for improved quality of life.

Abstract Background Autoimmune systemic inflammatory diseases are associated with an increased risk of cardiovascular disease, particularly myocardial infarction (MI). However, there are limited data on the prevalence and effects of inflammatory disease among U.S. adults who experience an MI at a young age. Purpose We sought to determine the prevalence and prognostic value of inflammatory disease in U.S. adults who experience an MI at a young age. Methods The YOUNG-MI registry is a retrospective cohort study of consecutive patients who experienced a Type 1 MI at or below the age of 50 years from 2000 to 2016 at two large medical centers. A diagnosis of rheumatoid arthritis (RA), psoriasis (PsO), systemic lupus erythematosus (SLE), or inflammatory arthritis was determined through physician review of electronic medical records (EMR). Demographic information, presence of cardiovascular (CV) risk-factors, medical procedures, and medications upon discharge were also ascertained from the EMR. Incidence of death was determined using a combination of EMR and national databases. Cox proportional hazard modeling was performed on a sub-sample following Mahalanobis Distance matching on age, sex, and CV risk factors. Results The cohort consisted of 2097 individuals (median age 45 years, 19% female, 53% ST-elevation MI). Among these, 53 (2.5%) individuals possessed a diagnosis of systemic inflammatory disease at or before their index MI (23% SLE, 9% RA, 64% PsO, 4% inflammatory arthritis). When compared to the remainder of the cohort, patients with a diagnosis of systemic inflammatory disease were more likely to be female (36% vs 19%, p=0.004) and be diagnosed with hypertension (62% vs 46%, p=0.025). There was, however, no significant difference in the prevalence of other CV risk factors – diabetes, smoking, dyslipidemia – or a family history of premature coronary artery disease. Despite these similarities, patients with inflammatory disease were less likely to be prescribed aspirin (88% vs 95%, p=0.049) or a statin (76% vs 89%, p=0.008) upon discharge. Over a median follow-up of 11.2 years, patients with inflammatory disease experienced an increased risk of all-cause mortality when compared with the full-cohort (Figure). Compared to the matched sample (n=138), patients with systemic inflammatory disease exhibited an increased risk of all-cause mortality (HR=2.68, CI [1.18 to 6.07], p=0.018), which remained significant after multivariable adjustment for length of stay and GFR (HR=2.38, CI [1.02 to 5.54], p=0.045). Conclusions Among individuals who experienced an MI at a young age, approximately 2.5% had evidence of a systemic inflammatory disease at or before their MI. When compared with a population of individuals with similar cardiovascular risk profiles, those with inflammatory disease had higher rates of all-cause mortality. Our findings suggest that the presence of a systemic inflammatory disorder is independently associated with worse long-term outcomes.

We performed a retrospective analysis involving 1269 patients with atrial fibrillation (AF) to evaluate the predictive value of the neutrophil-to-lymphocyte ratio (NLR) on long-term outcomes. The primary outcomes were all-cause mortality and combined end point events (CEEs). Cox proportional hazards regression analysis and net reclassification improvement (NRI) analysis were performed. During a median follow-up of 3.32 years, 285 deaths and 376 CEEs occurred. With the elevation of the NLR, the incidence of all-cause mortality (2.77, 4.14, 6.12, and 12.18/100 person-years) and CEEs (4.19, 7.40, 8.03, and 15.22/100 person-years) significantly increased. Multivariate Cox analysis indicated that the highest NLR quartile was independently associated with the incidence of all-cause mortality (hazard ratio [HR] = 1.77, 95% CI: 1.19-2.65) and CEEs (HR = 1.66, 95% CI: 1.18-2.33). When the NLR was analyzed as a continuous variable, a 1-unit increment in log NLR was related to 134% increased risk of all-cause mortality and 119% increased risk of CEEs. Net reclassification improvement analysis revealed that NLR significantly improved risk stratification for all-cause death and CEEs by 15.0% and 9.6%, respectively. Neutrophil-to-lymphocyte ratio could be an independent predictor of long-term outcomes in patients with AF.

Abstract Background: C-reactive protein (CRP), an acute-phase protein, is a sensitive systemic marker of inflammation and acute-phase reactions. Testing CRP concentrations at hospital admission may provide information about disease risk and overall survival. Methods: All first-ever transmittals to the department of medical and chemical laboratory diagnostics for determination of low-sensitivity CRP (n = 274 515, 44.5% male, median age 51 years) between January 1991 and July 2003 were included [median follow-up time: 4.4 years (interquartile range, 2.3–7.4 years)]. The primary endpoint was all-cause mortality. Multivariate Cox regression adjusted for sex and age was applied for analysis. Results: Compared to individuals within the reference category (CRP <5 mg/L), hazard ratios (HR) for all-cause mortality increased from 1.4 (5–10 mg/L category) to 3.3 in the highest category (>80 mg/L, all P <0.001). CRP was associated with various causes of death. The relation of CRP to cancer death was stronger than to vascular death. Younger patients with increased CRP had relatively far worse outcome than older patients (maximal HR: ≤30 years: 6.7 vs >60 years: 1.7–3.7). Interestingly, both short- and long-term mortality were associated with increasing CRP concentrations (>80 mg/L: HR 22.8 vs 1.4). Conclusion: Measurement of low-sensitivity CRP at hospital admission allowed for the identification of patients at increased risk of unfavorable outcome. Our findings indicate that close attention should be paid to hospitalized patients with high CRP not only because of very substantial short-term risk, but also long-term excess risk, the basis for which needs to be determined.

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.

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 Background Left-sided infectious endocarditis (IE) has a high 1-year mortality. Anemia is a common finding in patients with IE, yet little is known about frequency, severity, and associated outcomes in this setting. Purpose To examine the relationship between Hemoglobin (Hgb) level measured at IE stabilization (time of randomization) in the Partial Oral versus intravenous Antibiotic Treatment of Endocarditis (POET) trial - and long-term all-cause mortality. Methods In the POET trial, 400 patients with left-sided IE were randomized, after medical and/or surgical stabilization, to conventional antibiotic treatment or partial oral treatment. Only non-surgically treated patients were considered in this study. Patients were divided by quartiles into four groups based on Hgb level at randomization. Results We examined 248 patients with non-surgically treated IE. Median time from diagnosis of IE to randomization was 14 days (IQ 12–19). At long-term follow-up (median 3.2 years, IQ 2.18–4.60), 71 patients had died (28.6%). Patients in the lowest quantile (Hgb ≤6.0 mmol) had a HR of 4.17 (95% CI 1.81–9.61, p&lt;0.001) for death compared to patients in the highest quantile (Hgb &gt;7.5 mmol/L). This association remained significant after multivariable adjustment for age, sex, renal disease, C-Reactive Protein, and Prosthetic heart valve (HR 2.69, 95% CI 1.11–6.50); p=0.028). Conclusion Low Hemoglobin level at stabilization in patients with IE was associated with an increased risk of long-term mortality. Whether intensified treatment of anemia in patients with IE could improve long-term outcome requires investigation. Funding Acknowledgement Type of funding source: Foundation.

Abstract Aims Oral anticoagulants reduce the risk of ischaemic stroke but may increase the risk of major bleeding in atrial fibrillation (AF) patients. Little is known about the clinical outcomes of patients after a major bleeding event. This study assessed the outcomes of AF patients after major bleeding. Methods and results The Fushimi AF Registry is a community-based prospective survey of the AF patients in Fushimi-ku, Kyoto, Japan. Analyses were performed on 4304 AF patients registered by 81 institutions participating in the Fushimi AF Registry. We investigated the demographics and outcomes of AF patients who experienced major bleeding during follow-up period. During the median follow-up of 1307 days, major bleeding occurred in 297 patients (6.9%). Patients with major bleeding were older than those without (75.6 vs. 73.4 years; P &lt; 0.01). They were more likely to have pre-existing heart failure (33.7% vs. 26.7%; P &lt; 0.01), history of major bleeding (7.7% vs. 4.0%; P &lt; 0.01), and higher mean HAS-BLED score (2.05 vs.1.73; P &lt; 0.01). On landmark analysis, ischaemic stroke or systemic embolism occurred in 17 patients (3.6/100 person-years) after major bleeding and 227 patients (1.7/100 person-years) without major bleeding, with an adjusted hazard ratio (HR) of 1.93 [95% confidence interval (CI), 1.06–3.23; P = 0.03]. All-cause mortality occurred in 97 patients with major bleeding (20.0/100 person-years) and 709 (5.1/100 person-years) patients without major bleeding [HR 2.73 (95% CI, 2.16–3.41; P &lt; 0.01)]. Conclusion In this community-based cohort, major bleeding is associated with increased risk of subsequent all-cause mortality and thromboembolism in the long-term amongst AF patients.

Purpose Childhood cancer survivors are at increased risk for adverse outcomes and chronic medical conditions. Treatment-related scarring, disfigurement, and persistent hair loss, in addition to their long-term impact on psychological distress or health-related quality of life (HRQOL), have received little attention. Patients and Methods Self-reported scarring/disfigurement and persistent hair loss were examined in 14,358 survivors and 4,023 siblings from the Childhood Cancer Survivor Study. Multivariable models were used to examine associations with demographic and cancer treatment. The impact of disfigurement and hair loss on HRQOL (ie, Medical Outcomes Short Form–36) and emotional distress (ie, Brief Symptom Inventory–18) was examined. Results Survivors reported a significantly higher rate of scarring/disfigurement compared with siblings for head/neck (25.1% v 8.4%), arms/legs (18.2% v 10.2%), and chest/abdomen (38.1% v 9.1%), as well as hair loss (14.0% v 6.3%). In age-, sex-, and race-adjusted models, cranial radiation exposure ≥ 36 Gy increased risk for head/neck disfigurement (relative risk [RR], 2.42; 95% CI, 2.22 to 2.65) and hair loss (RR, 4.24; 95% CI, 3.63 to 4.95). Adjusting for cranial radiation, age, sex, race, education, and marital status, survivor hair loss increased risk of anxiety (RR, 1.60; 95% CI, 1.23 to 2.07), whereas head/neck disfigurement increased risk of depression (RR, 1.19; 95% CI, 1.01 to 1.41). Limitations due to emotional symptoms were associated with head/neck disfigurement (RR, 1.24; 95% CI, 1.10 to 1.41), arm/leg disfigurement (RR, 1.19; 95% CI, 1.05 to 1.35), and hair loss (RR, 1.26; 95% CI, 1.09 to 1.47). Conclusion Survivors of childhood cancer are at increased risk for disfigurement and persistent hair loss, which is associated with future emotional distress and reduced quality of life. Future studies are needed to better identify and manage functional outcomes in these patients.
