Background:There has been no large multicenter clinical trial on the prognosis of implantable cardioverter defibrillator (ICD) or cardiac resynchronization therapy with a defibrillator (CRT-D) in Japanese patients with coronary artery disease (CAD). The aim of the present study was to compare differences in the prognoses of Japanese patients with CAD between primary and secondary prevention, and to identify potential predictors of prognosis.Methods and Results:We investigated 392 CAD patients (median age 69 years, 90% male) treated with ICD/CRT-D enrolled in the Japan Implantable Devices in CAD (JID-CAD) Registry. The primary endpoint was all-cause death, and the secondary endpoint was appropriate ICD therapies. Endpoints were assessed by dividing patients into primary prevention (n=165) and secondary prevention (n=227) groups. The mean (±SD) follow-up period was 2.1±0.9 years. The primary endpoint was similar in the 2 groups (P=0.350).Conclusions:The mortality rate in Japanese patients with CAD who underwent ICD/CRT-D implantation as primary prevention was not lower than that of patients who underwent ICD/CRT-D implantation as secondary prevention, despite the lower cardiac function in the patients undergoing ICD/CRT-D implantation as primary prevention.

Background: It remains controversial whether a cancer history increases the risk of cardiovascular (CV) events among patients with myocardial infarction (MI) who undergo revascularization.Methods and Results: Patients who were confirmed as type 1 acute MI (AMI) by coronary angiography were retrospectively analyzed. Patients who died in hospital or those not undergoing revascularization were excluded. Patients with a cancer history were compared with those without it. A cancer history was examined in the in-hospital cancer registry. The primary outcome was a composite of cardiac death, recurrent type 1 MI, post-discharge coronary revascularization, heart failure hospitalization, and stroke. Among 551 AMI patients, 55 had a cancer history (cancer group) and 496 did not (non-cancer group). Cox proportional hazards model revealed that the risk of composite endpoint was significantly higher in the cancer group than in the non-cancer group (adjusted hazard ratio [HR]: 1.78; 95% confidence interval [CI]: 1.13–2.82). Among the cancer group, patients who were diagnosed as AMI within 6 months after the cancer diagnosis had a higher risk of the composite endpoint than those who were diagnosed as AMI 6 months or later after the cancer diagnosis (adjusted HR: 5.43; 95% CI: 1.55–19.07).Conclusions: A cancer history increased the risk of CV events after discharge among AMI patients after revascularization.

Background Normal values for echocardiographic measurements and the relationship between these parameters and age in a large Japanese population are still unknown. Methods and Results A total of 700 healthy Japanese aged 20-79 years underwent 2-dimensional and Doppler echocardiography at collaborating institutions. The respective mean values obtained in men and women were as follows: septal wall thickness, 0.9±0.1 and 0.8±0.1 cm; posterior wall thickness, 0.9±0.1 and 0.8±0.1 cm; left ventricular (LV) diastolic diameter, 4.8±0.4 and 4.4±0.3 cm; LV systolic diameter, 3.0±0.4 and 2.8±0.3 cm; LV diastolic volume, 93±20 and 74±17 ml; LV systolic volume, 33±20 and 25±7 ml; LV ejection fraction, 64±5 and 66±5%; maximum left atrial (LA) volume, 42±14 and 38±12 ml. Aortic root diameter, LV wall thickness, and LV mass slightly increased with age, whereas indexed LA volume did not vary with age. Diastolic parameters assessed by mitral inflow and mitral annular velocities declined with age, as previously reported. Conclusions Normal values of echocardiographic measurements in a large Japanese population are reported for the first time; several systolic and diastolic parameters varied with age. These results provide important reference values that should be useful in routine clinical practice as well as in clinical trials. (Circ J 2008; 72: 1859 - 1866)

Neurological Diving Accidents in Japanese Breath-Hold Divers: A Preliminary Report: Kiyotaka KoHSHI, et al. Department of Neurosurgery and Division of Hyperbaric Medicine, University of Occupational and Environmental Health—There have been no reports of diving accidents involving Korean or Japanese professional breath-hold (ama) divers except for our 2 recent cases. We investigated a direct interview survey on their village to determine whether other ama divers had experienced any accidents during or after dives. Interview responses were retrospectively obtained from 16 partially assisted male ama divers belonging to the Utsu Union on Mishima Island, Yamaguchi Prefecture in Japan. We questioned the divers about diving history (diving depth, length of the diving shift, number of dives and diving accidents), medical history (hypertension, cardiac arrhythmia, diabetes mellitus, and cerebrovascular diseases) and health habits (smoking and alcohol consumption). Nine of 16 ama divers previously had stroke-like neurological accidents, in which the most common symptom were unilateral motor weakness [7 cases] and sensory abnormalities [4 cases]. All of these neurological problems had manifested transiently. In addition, 13 of 16 divers had occasional episodes of dizziness, nausea and/or euphoria during such dives. Repeated deep breathhold dives may be harmful to the divers and cause brain involvement. (J Occup Health 2001; 43: 56-60)

Background: The purpose of the present study was to investigate gender differences in age-related changes of left ventricular (LV) and right ventricular (RV) geometries and functions throughout the entire adult age range using the Japanese Normal Values for Echocardiographic Measurements Project (JAMP) study database. Methods and Results: Seven hundred healthy volunteers (aged 20-79 years) underwent 2-dimensional and Doppler echocardiography. The subjects were stratified into 6 different age groups and then stratified by gender in each age group. LV diastolic function was assessed from pulsed wave Doppler measurements of mitral early (E) and late (A) inflow velocities and tissue Doppler measurements of mitral early (e') and late (a') annular velocities. LV volume decreased and LV mass increased with age to a similar extent in both men and women. Furthermore, for subjects <50 years, women had significantly greater E, E/A ratio and e' than men, but these parameters were similar between genders in subjects >50 years. In addition, there was a significant interaction between age and gender that affected the differences in E, e' and E/e' among the groups (P<0.03, P<0.01, and P<0.03, respectively; ANOVA). There were no gender differences in age-related changes in RV parameters. Conclusions: Gender differences were found in age-related changes in LV diastolic function in a healthy population. Gender differences should be considered for optimal diagnosis and management of cardiovascular disease. (Circ J 2011; 75: 2840-2846)
