Background:Given the high prevalence of heart failure (HF) in the elderly, it is essential to establish medical coordination between general practitioners (GPs) and acute care hospitals (ACHs) in an aging society. The aim of this study was to elucidate the status of acceptance of elderly patients with HF and their management requirements in a comprehensive community health system. Furthermore, we investigated GPs’ interest in using information and communications technology (ICT) in patient care.Methods and Results:We sent a questionnaire survey to 1,800 GPs in January 2015 and received 392 replies. The overall prevalence of home visits was 55%, with no differences according to GP background characteristics or geographic area. However, less than half (44%) reported accepting patients with symptomatic HF for treatment in their clinic. In addition, only 3 GPs reported accepting and providing emergency visits for patients with refractory HF. In particular, GPs who were not certificated cardiologists, female, and older showed poorer acceptance of symptomatic HF patients. More than half the GPs wanted the prompt acceptance by ACHs of emergency patients, followed by strengthening of home care support at discharge and support for end-of-life care. Half the GPs were interested in telemedicine.Conclusions:ACHs must promptly accept patients with HF in cases of emergency and strengthen nursing care support at discharge. It is also necessary to consider how to support older and female GPs.

Background: Although highly sensitive assays for troponin T (hs-TnT) have been developed, the sensitivity and specificity of hs-TnT for diagnosing acute coronary syndrome (ACS) remains imperfect. We evaluated the diagnostic value of a new biomarker of plaque vulnerability (soluble lectin-like oxidized low-density lipoprotein receptor-1, sLOX-1) as compared with hs-TnT in the emergency room (ER). Methods and Results: Plasma sLOX-1 and serum hs-TnT levels were measured in 200 consecutive patients presenting with chest symptoms and ECG abnormalities in the ER (116 ST elevation ACS [STEACS], 44 non-ST elevation ACS [NSTEACS], 40 non-ACS). The non-ACS group consisted of patients with cardiovascular diseases such as coronary spastic angina pectoris, pulmonary thromboembolism, perimyocarditis and takotsubo cardiomyopathy. Levels of sLOX-1 and hs-TnT were significantly higher in STEACS and NSTEACS than in non-ACS patients. The receiver-operating characteristic (ROC) curves of sLOX-1 and hs-TnT for detecting ACS, using the non-ACS patients as negative references, showed that the area under the curve (AUC) values of sLOX-1 and hs-TnT were 0.769 and 0.739, respectively. In the lower hs-TnT (<0.0205ng/ml) subgroup, the AUC value of the ROC curve of sLOX-1 for detecting ACS was 0.869. Conclusions: The diagnostic value for ACS was comparable between sLOX-1 and hs-TnT, and the accuracy of ACS diagnosis appeared to improve when sLOX-1 and hs-TnT were measured in combination.

It has been reported that green tea consumption reduces the risk of coronary artery disease and cardiac events. Catechin is a major constituent of Japanese green tea and an antioxidant. Lipids and oxidization of low-density lipoprotein cholesterol (LDL-C) play important roles in atherosclerosis. Therefore, we evaluated the effect of catechin intake on the lipid profile and plasma oxidized LDL. The study population consisted of 40 healthy adult volunteers (10 men, 30 women). Catechin was extracted from green tea leaves. The subjects were randomly divided into two groups, a catechin group (n = 29) and a control group (n = 11). In the catechin group, catechin (500 mg: equivalent to 6 or 7 cups of green tea) was administered orally. Venous blood samples were obtained before eating a meal at the start and after 4 weeks without any lifestyle modification. Plasma oxidized LDL assay was performed with a sandwich-type enzyme immunoassay using anti-oxidized phosphatidylcholine monoclonal antibody. The baseline lipid profiles and tea consumptions were similar between the two groups. Plasma oxidized LDL was significantly decreased after catechin administration (from 9.56 ± 9.2 to 7.76 ± 7.7 U/mL, P = 0.005), while plasma LDL-C, triglyceride, and HDL-C concentrations did not change. Catechin decreased the plasma oxidized LDL concentration without significant change in plasma LDL concentration. The mechanism of the beneficial effects of green tea on coronary artery disease might result from a decrease in plasma oxidized LDL.

Background: A rapid heart rate (HR) during atrial fibrillation (AF) and atrial flutter (AFL) in left ventricular (LV) dysfunction often impairs cardiac performance. The J-Land study was conducted to compare the efficacy and safety of landiolol, an ultra-short-acting β-blocker, with those of digoxin for swift control of tachycardia in AF/AFL in patients with LV dysfunction. Methods and Results: The 200 patients with AF/AFL, HR ≥120beats/min, and LV ejection fraction 25–50% were randomized to receive either landiolol (n=93) or digoxin (n=107). Successful HR control was defined as ≥20% reduction in HR together with HR <110beats/min at 2h after starting intravenous administration of landiolol or digoxin. The dose of landiolol was adjusted in the range of 1–10μg·kg–1·min–1 according to the patient’s condition. The mean HR at baseline was 138.2±15.7 and 138.0±15.0beats/min in the landiolol and digoxin groups, respectively. Successful HR control was achieved in 48.0% of patients treated with landiolol and in 13.9% of patients treated with digoxin (P<0.0001). Serious adverse events were reported in 2 and 3 patients in each group, respectively. Conclusions: Landiolol was more effective for controlling rapid HR than digoxin in AF/AFL patients with LV dysfunction, and could be considered as a therapeutic option in this clinical setting.  (Circ J 2013; 77: 908–916)
