Calcium-Phosphorus Product Is Associated with Adverse Prognosis in Hospitalized Patients with Heart Failure and Chronic Kidney Disease.

It has been reported that high levels of calcium-phosphorus (Ca-P) product are an indicator of coronary calcification and mortality risk in patients undergoing chronic hemodialysis. In the present study, we aimed to evaluate the significance of Ca-P product to predict the prognosis of patients with heart failure (HF) and chronic kidney disease (CKD). We conducted a prospective observational study of 793 patients with decompensated HF and CKD, and measured the value of Ca-P product. The cut-off value was obtained from the survival classification and regression tree (CART) analysis to predict post-discharge all-cause mortality and/or worsening HF, and the patients were divided into 2 groups: a high group (Ca-P product > 28, n = 594) and a low group (Ca-P product ≤ 28, n = 199). We compared the patient baseline characteristics and post-discharge prognosis between the 2 groups. The age as well as the prevalence of male sex, ischemic etiology, and anemia were significantly higher in the low group than in the high group. In contrast, there was no difference in echocardiographic parameters between the 2 groups. In the Kaplan-Meier analysis (mean follow-up 1089 days), all-cause mortality and/or worsening HF event rates were higher in the low group than in the high group (log-rank P = 0.001). In the multivariable Cox proportional hazard analysis, lower Ca-P product was found to be an independent predictor of all-cause mortality and/or worsening HF (hazard ratio 0.981, P = 0.031). Lower Ca-P product predicts adverse prognosis in patients with HF and CKD.

Prognostic Effects of Changes in Right Ventricular Fractional Area Change in Patients With Heart Failure.

BACKGROUND: It is still unclear whether changes in right ventricular function are associated with prognosis in heart failure (HF) patients. This study aimed to examine the prognostic effect of changes in right ventricular fractional area change (RVFAC).Methods and Results: This study enrolled 480 hospitalized patients with decompensated HF, and measured RVFAC with echocardiography at discharge (first examination) and post-discharge in the outpatient setting (second examination). RVFAC was divided into 3 categories: >35% in 314 patients, 25-35% in 108 patients, and <25% in 58 patients. Next, based on changes in RVFAC from the first to the second examination, the patients were further classed into 4 groups: (1) Preserved/Unchanged (preserved and unchanged RVFAC, n=235); (2) Reduced/Improved (improved RVFAC in at least 1 category, n=106); (3) Reduced/Unchanged (reduced and unchanged RVFAC, n=47); and (4) Preserved or Reduced/Worsened (deteriorated RVAFC in at least 1 category, n=92). Multivariate logistic regression analysis revealed that chronic kidney disease and anemia were the predictors of the preserved or reduced/worsened RVFAC. In the Kaplan-Meier analysis, changes in RVFAC were associated with the cardiac event rate and all-cause mortality. In the multivariable Cox proportional hazard analysis, the preserved or reduced/worsened RVFAC was an independent predictor of cardiac events and all-cause mortality. CONCLUSIONS: Changes in RVFAC were associated with post-discharge prognosis in hospitalized heart failure patients.

B-type natriuretic peptide is associated with the occurrence of bleeding events in heart failure patients with a history of coronary artery disease.

BACKGROUND: Bleeding risk in heart failure (HF) patients with coronary artery disease (CAD) has not yet been fully investigated. METHODS: We analyzed the data of 677 patients with a previous history of CAD who were hospitalized for HF. The patients were divided into three groups based on the tertiles of B-type natriuretic peptide (BNP) levels: Low, Middle, and High BNP groups (n = 225, 226, and 226, respectively). The primary endpoint was post-discharge bleeding events, which was defined as hemorrhagic stroke and gastrointestinal bleeding. RESULTS: The High BNP group was the oldest (Low, Middle, High, 67.0, 74.0, and 75.0 years, respectively; p < 0.001), showed the lowest left ventricular ejection fraction (56.0%, 50.7%, and 40.3%, respectively; p < 0.001), and contained more patients at high bleeding risk (HBR) defined by the simplified version of the Academic Research Consortium for High Bleeding Risk (ARC-HBR) definition (65.3%, 85.4%, and 93.8%, respectively, p < 0.001). Kaplan-Meier analysis demonstrated that post-discharge bleeding events occurred most frequently in the High BNP group (log-rank p = 0.008). In the Cox proportional hazard analysis, compared to the Low BNP group as a reference, the High BNP group was independently associated with bleeding events after adjustment for age, sex, simplified ARC-HBR definition, and left ventricular ejection fraction (hazard ratio 3.208, 95% confidence interval 1.078-9.544, p = 0.036). CONCLUSIONS: High BNP is associated with bleeding events in HF patients with a history of CAD.

The efficacy of combination of transcatheter atrial septal defects closure and radiofrequency catheter ablation for the prevention of atrial fibrillation recurrence through bi-atrial reverse remodeling.

PURPOSE: Atrial fibrillation (AF) often coexists with atrial septal defects (ASD). Each of the transcatheter closure for ASD and radiofrequency catheter ablation (RFCA) for AF have been established as the first-line therapy. However, there are limited data about therapeutic effect RFCA plus transcatheter ASD closure on AF recurrence in AF patients with ASD. The aim of the current study was to investigate the clinical impact of ASD closure following RFCA on AF recurrence. METHODS: Forty-two ASD patients (17 males and 54 ± 20 years old) were enrolled and classified into three groups: ASD occlusion-sinus rhythm (ASO-SR) (n = 26), no AF history prior to ASD closure; ASO-AF-RFCA (n = 11), RFCA was performed due to AF history before ASD closure; and ASO-AF-anti-arrhythmic drug (ASO-AF-AAD) (n = 5), AF was treated with AAD before and after ASD closure. AF occurrence among the 3 groups was evaluated. RESULTS: Kaplan-Meier analysis showed that ASO-SR and ASO-AF-RFCA groups showed a lower AF occurrence ratio than ASO-AF-AAD group during the 14- ± 9-month follow-up periods (P = 0.013). AF occurrence in ASO-SR and ASO-AF-RFCA groups was comparable (P = 0.480). Bi-atrial reverse remodeling, such as decrease in left atrial volume index (P = 0.049) and right atrial area (P = 0.046), and significant decrease in high-sensitivity C-reactive protein levels (P = 0.049) were identified in ASO-AF-RFCA group, but not in ASO-AF-AAD group. CONCLUSION: A combination of two percutaneous therapies was proven to be effective and induced bi-atrial reverse remodeling in association with inflammatory reaction.

B-type natriuretic peptide is associated with post-discharge stroke in hospitalized patients with heart failure.

AIMS: Recently, B-type natriuretic peptide (BNP) has been attracting attention as a predictor of stroke in patients with atrial fibrillation or those with prior stroke experience. However, the association between BNP and stroke has not been examined in patients with chronic heart failure (CHF). In the current study, we assessed whether BNP is associated with future occurrence of stroke in patients with CHF. METHODS AND RESULTS: We prospectively studied 1803 consecutive patients who were admitted for decompensated HF and assessed the predictive value of circulating BNP levels for occurrence of post-discharge stroke. A total of 69 (3.8%) patients experienced a stroke (the stroke group) during the post-discharge follow-up period of a median of 1150 days. The stroke group showed a higher CHADS2 score. With respect to past medical history, the stroke group had a higher prevalence of arterial hypertension, atrial fibrillation, prior stroke, and chronic kidney disease. Echocardiographic parameters showed no significant differences between the two groups. In contrast, BNP levels were significantly higher in the stroke group than in the non-stroke group (452.1 vs. 222.7 pg/mL, P < 0.001). Multivariate Cox proportional hazard analysis indicated that BNP levels were independently associated with post-discharge stroke (hazard ratio 2.636, 95% confidence interval 1.595-4.357, P < 0.001). The survival classification and regression tree analysis revealed that the accurate cut-off point of BNP in predicting post-discharge stroke was 187.7 pg/mL. We added high BNP level (BNP ≥ 180 pg/mL) as one point to CHADS2 score. The BNP-added CHADS2 score was compared with CHADS2 score alone by using c-statistics. The areas under the curve of CHADS2 score, BNP, and BNP-added CHADS2 score were 0.698, 0.616, and 0.723, respectively. The predictive value of BNP-added CHADS2 score was higher compared with those of CHADS2 score (P = 0.026). CONCLUSIONS: The assessment of BNP may predict the occurrence of stroke in CHF patients used alone or in combination with established CHADS2 score.

[Functional improvement program of musculoskeletal system of the elderly in an isolated island of Kagoshima prefecture].

Under the coming amendment of long term care insurance (LTCI), the preventive activities will be more strengthened in order to ameliorate the quality of life (QOL) levels of the slightly frail elderly and then to rationalize the LTCI expenditures. The functional training of the musculoskeletal system is regarded as especially important. In order to validate its effectiveness and availability in a rural setting, we organized a physical fitness program for the slightly frail elderly in an isolated island of Kagoshima prefecture. According to the results of our preliminary study, statistically significant improvement was observed for some items of the physical fitness level, but not for life style, activities of daily living (ADL), instrumental activities of daily living (IADL) levels or Frenchay Activities Index. In addition to the relatively small number of participants, it is thought that physical fitness training alone cannot increase the elderly activity volume. Further studies are necessary to clarify the usefulness of physical training on the ADL/IADL level of the elderly.

[Effect of oral health care program on the oral function of the elderly].

In order to prepare a new prevention program under the long term care insurance from the fiscal year 2006, we have organized an oral health care program for the elderly in a town of Kagoshima prefecture. We conducted a series of oral health education, i.e., instruction on brushing and flossing, and oral function exercises. Before and after the three months program, we evaluated the unstimulated and stimulated salivary flow rate, the counts of S. mutans, the counts of repetitive saliva swallowing test (RSST), bilateral bite force and the number of permanent teeth and artificial teeth. According to the results, a statistically significant improvement was observed in RSST and the unstimulated and stimulated salivary flow rate, but not in the S. mutans level and bite force. The present research suggests the effectiveness of the oral health care program for the aged. A larger sized and longer period intervention will be necessary in order to validate our findings.

Multiple Intestinal Ulcers Associated with Primary Epstein-Barr Virus Infection in a Patient with Rheumatoid Arthritis Undergoing Methotrexate Therapy.

A 47-year-old woman with a 2-year history of rheumatoid arthritis (RA) undergoing methotrexate treatment developed a perforated ulcer in the ileum for which she underwent emergency surgery. A histological analysis of the extirpated specimen presented a possible Epstein-Barr virus (EBV) infection in the ulcerative lesion without a feature of lymphoproliferative disorder. Interestingly, the patient's serological tests with a paired serum diagnosed a primary EBV infection. The present case emphasizes the importance of being aware of severe enteritis as a possibility for patients with RA, for an accurate diagnosis.
