RESUMEN
Palliative care for end-stage heart failure should be provided by a multidisciplinary team. However, the influence of each occupational category on patients receiving palliative care for end-stage heart failure remains unclear. Thus, this study investigated the relationships between palliative care conferences and positive outcomes of palliative care for end-stage heart failure patients. We sent questionnaires to all cardiology training hospitals authorized by the Japanese Circulation Society (n = 1004); of these, responses from the directors at 554 institutions were analyzed. We divided the responding institutions into two groups according to their implementation of palliative care conferences for patients with end-stage heart failure. The institutions that had held such conferences (n = 223) had a larger number of hospital beds, beds in the cardiovascular department, and patients admitted to the cardiovascular department, compared with institutions that had not held these conferences (n = 321). The usage rates of opioids, non-steroidal anti-inflammatory drugs, and sedatives were significantly higher in institutions that held these conferences. Multivariate analysis revealed that nutritionists and medical social workers had greater involvement in the improvement of mental symptoms and ensuring that patients could stay where they wished, respectively. The presence of palliative care physicians, physical therapists, or pharmacists was associated with multiple positive outcomes. This study indicated that there are possible associations between palliative care conferences and positive outcomes when performing palliative care for patients with end-stage heart failure.

BACKGROUND: The aim of this study was to explore whether the pouch depth influenced the radiofrequency (RF) duration and total delivered RF energy for cavotricuspid isthmus (CTI) ablation and define the cutoff value for a deep pouch-specified ablation strategy. METHODS: This study included 94 atrial fibrillation (AF) patients (56 males, age 68 ± 8.0 years). With intracardiac echocardiography, the isthmus length and pouch depth were precisely measured. After a standard AF ablation, all patients underwent the CTI ablation along the lateral isthmus. If bidirectional block could not be achieved, the ablation catheter was deflected more than 90 degrees to ablate inside the pouch (knuckle-curve ablation). RESULTS: Seventy-two patients (76.6%) had a sub-Eustachian pouch. Bidirectional block could be achieved in all patients. By a univariate logistic regression analysis, only the pouch depth was significantly correlated with the RF duration (P = .005) and RF energy (P = .006). A multivariate logistic regression analysis also revealed the pouch depth was the sole factor that influenced the RF duration (P = .001) and RF energy (P = .001). Among the 72 patients, 21 patients needed a knuckle-curve ablation. Using a receiver operating characteristic curve, the optimal cutoff value of the pouch depth for a knuckle-curve ablation was 3.7 mm with a sensitivity of 90% and specificity of 69%. CONCLUSIONS: The sub-Eustachian pouch depth was the sole factor that influenced the RF duration and energy in the CTI ablation. If the pouch was deeper than 3.7 mm, a deep pouch-specified ablation strategy would be needed.
RESUMEN
BACKGROUND: Palliative care for heart failure (HF) patients is recommended in Western guidelines, so this study aimed to clarify the current status of palliative care for HF patients in Japan.MethodsâandâResults:A survey was sent to all Japanese Circulation Society-authorized cardiology training hospitals (n=1,004) in August 2016. A total of 544 institutions (54%) returned the questionnaire. Of them, 527 (98%) answered that palliative care is necessary for patients with HF. A total of 227 (42%) institutions held a palliative care conference for patients with HF, and 79% of the institutions had <10 cases per year. Drug therapy as palliative care was administered at 403 (76%) institutions; morphine (87%) was most frequently used. Among sedatives, dexmedetomidine (33%) was administered more often than midazolam (29%) or propofol (20%). Regarding the timing of end-of-life care, most institutions (84%) reported having considered palliative care when a patient reached the terminal stage of HF. Most frequently, the reason for the decision at the terminal stage was "difficulty in discontinuing cardiotonics." A major impediment to the delivery of palliative care was "difficulty predicting an accurate prognosis." CONCLUSIONS: This large-scale survey showed the characteristics of palliative care for HF in Japan. The present findings may aid in the development of effective end-of-life care systems.

BACKGROUND: The term palliative care has historically been associated with support for individuals with advanced incurable cancer, so cardiologists and cardiac nurses may be unfamiliar with its principles and practice. However, palliative care is now a part of end-stage heart failure management. We conducted the first nationwide survey to investigate the status of palliative care for heart failure in Japan. METHODS AND RESULTS: A self-reported questionnaire was mailed to all Japanese Circulation Society - authorized cardiology training hospitals (n=1004) in August 2016. The response deadline was December 2016. The survey focused on the following topics: basic information about the facility and multidisciplinary team, patient symptoms for palliative care, positive outcomes after providing palliative care, drug therapy as palliative care for patients with heart failure, advance care planning with patients and their families, and impediments to providing palliative care to patients with heart failure. The results of the survey will be reported in detail elsewhere. CONCLUSIONS: Current guidelines on palliative care do not specifically address what team members should be involved, what drugs should be used, or when palliative care should be started. This survey collected information to improve the quality of palliative care and provide more specialized palliative care within the limits of resources.

PURPOSE: In patients undergoing primary percutaneous coronary intervention (PCI) for the treatment of ST-segment elevation myocardial infarction (STEMI), coronary microvascular dysfunction is associated with poor prognosis. Coronary microvascular resistance is predominantly regulated by ATP-sensitive potassium (KATP) channels. The aim of this study was to clarify whether nicorandil, a hybrid KATP channel opener and nitric oxide donor, may be a good candidate for improving microvascular dysfunction even when administered after primary PCI. METHODS: We compared the beneficial effects of nicorandil and nitroglycerin on microvascular function in 60 consecutive patients with STEMI. After primary PCI, all patients received single intracoronary administrations of nitroglycerin (250 µg) and nicorandil (2 mg) in a randomized order; 30 received nicorandil first, while the other 30 received nitroglycerin first. Microvascular dysfunction was evaluated with the index of microcirculatory resistance (IMR), defined as the distal coronary pressure multiplied by the hyperemic mean transit time. RESULTS: As a first administration, nicorandil decreased IMR significantly more than did nitroglycerin (median [interquartile ranges]: 10.8[5.2-20.7] U vs. 2.1[1.0-6.0] U, p=0.0002).As a second administration, nicorandil further decreased IMR, while nitroglycerin did not (median [interquartile ranges]: 6.0[1.3-12.7] U vs. -1.4[-2.6 to 1.3] U, p<0.0001). The IMR after the second administration was significantly associated with myocardial blush grade, angiographic TIMI frame count after the procedure, and peak creatine kinase level. CONCLUSION: Intracoronary nicorandil reduced microvascular dysfunction after primary PCI more effectively than did nitroglycerin in patients with STEMI, probably via its KATP channel-opening effect.

BACKGROUND: The objective of this study was to investigate whether a distal protection (DP) device can preserve the index of microcirculatory resistance (IMR) after primary percutaneous coronary intervention (PCI) in patients with anterior ST-segment elevation myocardial infarction (STEMI). METHODS AND RESULTS: The study group of 36 consecutive patients with anterior STEMI were randomized into 2 groups of primary PCI with or without DP: stenting without DP (non-DP group, n = 17) and with DP (DP group, n = 19). The DP in all cases was Filtrap (Nipro, Japan). Following final coronary angiography after successful PCI, IMR was measured using PressureWire™ Certus (St Jude Medical, USA) at maximal hyperemia. The averaged IMR of the 36 patients with STEMI after primary PCI was 31.6U. The IMR in the DP group was significantly lower than that in the non-DP group (26.6 ± 25.8U vs. 37.2 ± 23.2U, P = 0.03242). CONCLUSIONS: DP as an adjunctive therapy of PCI for acute anterior STEMI may have beneficial effects on myocardial microcirculation because of preservation of IMR.
