Background: Heart failure with preserved ejection fraction (HFpEF) is an increasing health problem associated with high morbidity and mortality rates. Several reports have shown an association between hypokalemia and clinical outcomes in patients with heart failure (HF). However, the association of hypokalemia with kidney function and clinical outcomes in patients with HFpEF remains unclear.Methods and Results: We measured serum potassium levels and kidney function in 454 patients with HFpEF (mean age 76 years; 55% men) at admission. Hypokalemia (K+<3.5 mmol/L) and hyperkalemia (K+>5.0 mmol/L) were identified in 58 (12.7%) and 11 (2.4%) patients, respectively. Patients with hypokalemia showed renal tubular damage (RTD), defined as a urinary β2-microglobulin to creatinine ratio ≥300 μg/gCr, preserved estimated glomerular filtration rate (eGFR), and plasma volume expansion. Multivariate logistic analysis demonstrated that RTD, preserved eGFR, and plasma volume expansion were significantly associated with hypokalemia. During the median follow-up period of 1,000 days, 82 HF-related events occurred. Kaplan-Meier analysis showed that patients with hypokalemia had a higher rate of HF-related events than those without hypokalemia. Multivariate Cox proportional hazard regression analysis demonstrated that hypokalemia was significantly associated with HF-related events after adjusting for confounding factors.Conclusions: Hypokalemia is affected by kidney function, notably RTD, in patients with HFpEF. Hypokalemia is a risk factor for HF-related events in patients with HFpEF.

Background:Insulin resistance as assessed using homeostasis model assessment ratio (HOMA-R) is associated with latent myocardial damage in apparently healthy subjects in health check. Meanwhile, diabetes mellitus (DM) is an unfavorable prognostic risk factor in patients with heart failure (HF). We examined the impact of pancreatic β-cell dysfunction on clinical outcomes in HF patients without DM.Methods and Results:This study enrolled 312 HF patients without DM. Pancreatic β-cell dysfunction was defined as HOMA-β <30%. A total of 108 patients (35%) had β-cell dysfunction. Plasma brain natriuretic peptide was higher in patients with pancreatic β-cell dysfunction compared with those without (625.2 vs. 399.0 pg/mL, P<0.001). On Kaplan-Meier analysis, a significantly higher cardiovascular events rate was observed in patients with pancreatic β-cell dysfunction (log-rank test, P=0.001), but there was no significant difference between patients with and without insulin resistance. On Cox hazard analysis, pancreatic β-cell dysfunction was independently associated with cardiovascular events after adjustment for confounding factors (HR, 1.58; 95% CI: 1.02–2.45), whereas insulin resistance was not associated with cardiovascular events.Conclusions:Pancreatic β-cell dysfunction, but not insulin resistance, was associated with unfavorable outcome in HF patients without DM.

Background:Peripheral artery disease (PAD) is an athero-occlusive disease and a known risk factor for cardiovascular events. The controlling nutritional status (CONUT) score and geriatric nutritional risk index (GNRI) are objective tools for evaluating malnutrition and are reportedly associated with poor clinical outcomes in patients with fatal diseases. However, the effect of malnutrition on the clinical outcomes in patients with PAD remains unclear.

Background: Single nucleotide polymorphisms (SNPs) in nitric oxide synthase 3 (NOS3) are associated with cardiovascular risk factors. However, it is not clear whether the NOS3 SNP is a genetic risk factor for cardiovascular diseases.Methods and Results: This prospective cohort study included 2,726 subjects aged ≥40 years who participated in a community-based health checkup. We genotyped 639 SNPs, including 2 NOS3 SNPs (rs1799983 and rs1808593). All subjects were monitored prospectively over a median follow-up period of 16.0 years, with the endpoint being cardiovascular events, including cardiovascular death and/or non-fatal myocardial infarction. Kaplan-Meier analysis demonstrated that both rs1799983 GT/TT and rs1808593 GG carriers had a higher risk of the endpoint than non-carriers. Univariate and multivariate Cox proportional hazard regression analyses revealed that both rs1799983 GT/TT and rs1808593 GG were independently associated with cardiovascular events after adjusting for confounding risk factors. The net reclassification index and integrated discrimination index were significantly improved by the addition of NOS3 SNPs as cardiovascular risk factors.Conclusions:NOS3 gene polymorphisms could be genetic risk factors for cardiovascular events in the general Japanese population, and could be used to facilitate the early identification of individuals at high risk of cardiovascular events.

Background: Lower extremity artery disease (LEAD) is an arterial occlusive disease characterized by an insufficient blood supply to the lower limb arteries. The H2FPEF score, comprising Heavy, Hypertensive, atrial Fibrillation, Pulmonary hypertension, Elder, and Filling pressure, has been developed to identify patients at high risk of heart failure (HF) with preserved ejection fraction. This study assessed the impact of modified H2FPEF scores on chronic limb-threatening ischemia (CLTI) in patients with LEAD.Methods and Results: This study was a prospective observational study. Because the definition of obesity differs by race, we calculated the modified H2FPEF score using a body mass index >25 kg/m2to define obesity in 293 patients with LEAD who underwent first endovascular therapy. The primary endpoints were newly developed and recurrent CLTI. The secondary endpoint was a composite of events, including mortality and rehospitalization due to worsening HF and/or CLTI. The modified H2FPEF score increased significantly with advancing Fontaine classes. Multivariate Cox proportional hazard analysis revealed that the modified H2FPEF score was an independent predictor of newly developed and recurrent CLTI and composite events. The net reclassification index and integrated discrimination improvement were significantly improved by adding the modified H2FPEF score to the basic predictors.Conclusions: The modified H2FPEF score was associated with LEAD severity and future CLTI development, suggesting that it could be a feasible marker for patients with LEAD.

Background: Aortic artery disease (AAD), such as aortic dissection or aortic aneurysm rupture, is fatal, with an extremely high mortality. Because of its low incidence, the risk for the development of AAD has not yet been elucidated. Hypertension (HT) is an established risk factor for cardiovascular disease, but there has been no prospective study on the effect of HT on AAD-related mortality. Methods and Results: We used a nationwide database of 276,197 subjects (aged 40–75 years) who participated in the annual “Specific Health Check and Guidance in Japan” from 2008 to 2010. There were 80 AAD-related deaths during the follow-up period of 1,049,549 person-years. On multivariate Cox proportional hazard regression, HT was an independent risk factor for AAD-related death in apparently healthy subjects. On receiver operating characteristics curve analysis for AAD-related death, abnormal systolic and diastolic blood pressure (SBP and DBP) were 130 mmHg and 82 mmHg, respectively. The prediction capacity was significantly improved by the addition of SBP to confounding risk factors. Notably, further improvement of the C index was observed by addition of DBP to the model with SBP. Conclusions: This is the first report to prospectively show that HT is a risk factor for AAD-related death. Both SBP and DBP are of critical importance in the primary prevention of AAD-related death in apparently healthy subjects.
