From August 27th to 31st, the 2016 Annual Congress of the European Society of Cardiology (ESC 2016) was held in Fiera di Roma, Italy. Despite the socially unstable situation, more than 32,000 attendees, including clinical physicians, basic researchers, medical students, and paramedical personnel, as well as 5,000 exhibitors from 106 countries gathered in this historical city to share the latest findings and to discuss the present issues in cardiovascular medicine. There were scientific sessions, including 28 Hot Lines, 26 clinical trial updates, 24 registry studies, and 5 clinical practice guideline sessions. Japan had 1,170 attendees, with 1,743 submitted and 670 accepted abstracts, including the NIPPON trial presented in the hotline session. From 2011 to 2016, Japan has been the first abstract submitter and has had the most abstracts accepted, which indicates the great contribution of Japanese cardiologists and the Japanese Circulation Society. This report briefly introduces the key presentations and highlights from the ESC 2016 Scientific Sessions.

Background:Outcomes of cryoballoon ablation for paroxysmal atrial fibrillation (PAF) have been reported in the Western countries but not in Japan. The CRYO-Japan PMS study was a single-arm, observational, multicenter, prospective study of the 2nd-generation cryoballoon Arctic Front AdvanceTM. We evaluated device- and procedure-related complications and clinical outcomes at 6 months.Methods and Results:The 616 patients (male, 72%; mean age, 63±11 years) were enrolled from 33 Japanese hospitals. Of all patients, 610 had PAF, and procedural data were analyzed in 607. A subset of 328 patients was followed for 6 months for the primary efficacy analysis. AF recurrence outside the 3-month blanking period or repeat ablation was considered treatment failure. Pulmonary vein isolation was achieved in 606/607 patients (99.8%); 1 patient (0.3%) had a repeat ablation during the blanking period. Freedom from AF at 6 months was 88.4% (95% CI: 84.1–91.6%). Device- and/or procedure-related adverse events included phrenic nerve injury unresolved at hospital discharge in 9/616 patients (1.5%), which resolved within 6 months in 7, pericardial effusion in 5/616 (0.8%), and tamponade in 4/616 (0.6%). One non-device-related death from pneumonia was reported 6 days post-procedure.Conclusions:Cryoballoon ablation is safe and effective for Japanese PAF patients, with 88.4% AF freedom at 6 months post-ablation.

Background:Obstructive sleep apnea (OSA) is associated with activation of the sympathetic nervous system, and patients with this condition often experience elevated blood pressure (BP), increased BP variability, and nocturnal BP surges.Methods and Results:The SYMPLICITY HTN-3 trial was a large prospective, randomized, blinded, sham-controlled trial of renal denervation for treatment of uncontrolled, apparently treatment-resistant hypertension. In a post hoc analysis, we examined the effect of renal denervation vs. sham control on office and ambulatory (including nocturnal) systolic BP in patients with and without OSA. 26% (94/364) of renal denervation subjects and 32% (54/171) of sham control subjects had OSA. Baseline office and nighttime systolic BP values were similar in both arms, including in subjects with and without OSA. Compared with sham control, renal denervation reduced the 6-month office systolic BP in subjects with (−17.0±22.4 vs. −6.3±26.1 mmHg, P=0.01) but not in subjects without OSA (−14.7±24.5 vs. −13.4±26.4 mmHg, P=0.64), P=0.07 for the interaction between treatment arm and OSA status. In those with sleep apnea, renal denervation was also associated with a reduction in maximum (−4.8±21.8 vs. 4.5±24.6 mmHg, P=0.03) and average peak (−5.6±20.4 vs. 3.2±22.4 mmHg, P=0.02) nighttime systolic BP.Conclusions:OSA subjects appeared to be responsive to renal denervation therapy. However, this hypothesis requires prospective testing.

Background:We investigated the effects of age and low diastolic blood pressure (DBP) on cardiovascular death in patients with coronary artery disease (CAD) after coronary revascularization.Methods and Results:Stable, chronic CAD patients after coronary revascularization in the CREDO-Kyoto registry cohort-1 were allocated to the Young (≤64 years, n=2,619), Young-Old (65–74 years, n=2,932), and Old-Old (≥75 years, n=1,629) groups. Kaplan-Meier analysis showed that the crude cumulative incidence of cardiovascular death was higher in Young-Old patients with DBP <70 mmHg (P<0.001) and in Old-Old patients with DBP <60 mmHg (P=0.017), but not <70 mmHg (P=0.629), compared with each counterpart. Low DBP did not increase cardiovascular death in young patients. After adjustments with independent predictors, DBP <60 mmHg did not increase the cardiovascular death in the Old-Old group (HR=1.579 [95% CI, 0.944–2.642], P=0.082) and DBP <70 mmHg remained a predictor in the Young-Old group (HR=1.665 [1.094–2.532], P=0.017). On multivariate stepwise Cox proportional hazard regression analysis, independent predictors for cardiovascular death in low DBP patients were creatinine clearance (CCr; inversely), prior cerebrovascular disease, and aortic disease in the Young-Old group and CCr (inversely) and malignancy in the Old-Old group.Conclusions:DBP <60 mmHg was not an independent factor for predicting cardiovascular death in Old-Old revascularized CAD patients, whereas DBP <70 mmHg remained a predictor in the Young-Old.

Despite advancements in pharmacological therapy and refinement of the tools and technique of primary percutaneous coronary intervention (PCI) and coronary artery bypass surgery, patients with acute myocardial infarction (AMI) complicated by profound cardiogenic shock (CS) still have unacceptably high in-hospital mortality and unfavorable long-term outcome. Thus, there is an imminent need of a new and safe treatment modality in the management of AMI complicated by profound CS. Growing evidence suggests that extracorporeal membrane oxygenator (ECMO)-supported primary PCI is an effective therapeutic option for saving lives under such conditions. In this review, we describe and interpret the potential role of circulatory mechanical support by ECMO in the setting of AMI complicated by profound CS for improving clinical outcomes.

Myocardial infarction with non-obstructive coronary arteries (MINOCA) is an intriguing clinical entity that is being increasingly recognized with the more common use of coronary angiography during acute myocardial infarction. This review systematically addresses the contemporary understanding of MINOCA, including, (1) what are the diagnostic criteria, (2) when the diagnosis should be considered, (3) who is at risk, (4) why this new syndrome should be diagnosed, (5) how these patients should be managed, and (6) where to next?

Background:Mean pulmonary arterial pressure (MPAP) is an important pulmonary hemodynamic parameter used in the management of patients with chronic thromboembolic pulmonary hypertension (CTEPH). We compared echocardiography-derived estimates of MPAP with right heart catheterization (RHC) to identify reliable noninvasive methods of estimating MPAP-derived RHC (MPAPRHC) in these patients.Methods and Results:Echocardiography and RHC were performed in 56 patients with CTEPH (60.5±12.0 years; 44 females). We measured the tricuspid regurgitation (TR) pressure gradient (TRPG) using echocardiography. The mean systolic right ventricular (RV)-right atrial (RA) gradient was calculated by tracing the TR time velocity flow. Systolic and mean pulmonary artery pressures (SPAPTRand MPAPTR) estimated from TRPG and mean systolic RV-RA gradient were calculated by adding RA pressure based on the inferior vena cava. MPAPChemlawas calculated using Chemla’s formula: 0.61×SPAPTR+2 mmHg. MPAPRHCand pulmonary vascular resistance were 35.9±11.3 mmHg and 6.6±3.6 Wood units, respectively. The mean difference from MPAPRHCand limits of agreement were −1.5 mmHg and −19.6 to 16.5 mmHg for MPAPTR, and −4.6 mmHg and −24.5 to 15.2 mmHg for MPAPChemla. Accuracy within 10 mmHg and 5 mmHg of MPAPRHCwas 80.4% and 46.4% for MPAPTR, and 71.4% and 48.2% for MPAPChemla, respectively.Conclusions:MPAPTRand MPAPChemlaare reliable estimates for MPAPRHCin patients with CTEPH.

Background:The J-RHYTHM Registry 2 was a multicenter, prospective observational study that extended the follow-up period of the J-RHYTHM Registry in order to investigate long-term outcomes and effects of non-vitamin K antagonist oral anticoagulants (NOACs) in Japanese patients with atrial fibrillation (AF).Methods and Results:Among 6,616 patients with nonvalvular AF (NVAF) (men 71.0%, 69.7±9.9 years, CHADS2score 1.7±1.2), event rates were compared among patients receiving warfarin (n=3,964), NOACs (n=923), and no anticoagulation therapy (No-OAC, n=753) at the end of follow-up, except for 976 patients lacking anticoagulant data. During the 5-year follow-up period, thromboembolism occurred in 196 (4.9%), 19 (2.1%), and 45 (6.0%) patients, respectively; major hemorrhage in 233 (5.9%), 22 (2.4%), and 36 (4.8%); all-cause death in 230 (5.8%), 13 (1.4%), and 105 (13.9%), (P<0.001 for each). After adjusting for the components of the CHA2DS2-VASc score and antiplatelet drug use, the odds ratio (OR) in the Warfarin group was significantly lower for all-cause death compared with that in the No-OAC group (OR 0.30, 95% confidence interval [CI] 0.23–0.39, P<0.001), whereas ORs in the NOACs group were significantly lower for all events (OR 0.42, 95% CI 0.24–0.74, P=0.003 for thromboembolism; OR 0.53, 95% CI 0.31–0.93, P=0.027 for major hemorrhage; and OR 0.10, 95% CI 0.06–0.18, P<0.001 for all-cause death, respectively).Conclusions:NOACs could be beneficial for reducing event rates of all types in Japanese NVAF patients.

Background:Waon therapy improves heart failure (HF) symptoms, but further evidence in patients with advanced HF remains uncertain.Methods and Results:In 19 institutes, we prospectively enrolled hospitalized patients with advanced HF, who had plasma levels of B-type natriuretic peptide (BNP) >500 pg/ml on admission and BNP >300 pg/ml regardless of more than 1 week of medical therapy. Enrolled patients were randomized into Waon therapy or control groups. Waon therapy was performed once daily for 10 days with a far infrared-ray dry sauna maintained at 60℃ for 15 min, followed by bed rest for 30 min covered with a blanket. The primary endpoint was the ratio of BNP before and after treatment. In total, 76 Waon therapy and 73 control patients (mean age 66 years, men 61%, mean plasma BNP 777 pg/ml) were studied. The groups differed only in body mass index and the frequency of diabetes. The plasma BNP, NYHA classification, 6-min walk distance (6MWD), and cardiothoracic ratio significantly improved only in the Waon therapy group. Improvements in NYHA classification, 6MWD, and cardiothoracic ratio were significant in the Waon therapy group, although the change in plasma BNP did not reach statistical significance. No serious adverse events were observed in either group.Conclusions:Waon therapy, a holistic soothing warmth therapy, showed clinical advantages in safety and efficacy among patients with advanced HF.

Background:It has been shown that serum lipoprotein(a) [Lp(a)] is elevated in familial hypercholesterolemia (FH) with mutation(s) of the LDL receptor (LDLR) gene. However, few data exist regarding Lp(a) levels in FH with gain-of-function mutations of the PCSK9 gene.Methods and Results:We evaluated 42 mutation-determined heterozygous FH patients with aPCSK9gain-of-function mutation (FH-PCSK9, mean age 52, mean LDL-C 235 mg/dl), 198 mutation-determined heterozygous FH patients with aLDLRmutation (FH-LDLR, mean age 44, mean LDL-C 217 mg/dl), and 4,015 controls (CONTROL, mean age 56, mean LDL-C 109 mg/dl). We assessed their Lp(a), total cholesterol, triglycerides, HDL-C, LDL-C, use of statins, presence of hypertension, diabetes, chronic kidney disease, smoking, body mass index (BMI) and coronary artery disease (CAD). Multiple regression analysis showed that HDL-C, use of statins, presence of hypertension, smoking, BMI, and Lp(a) were independently associated with the presence of CAD. Under these conditions, the serum levels of Lp(a) in patients with FH were significantly higher than those of the CONTROL group regardless of their causative genes, among the groups propensity score-matched (median Lp(a) 12.6 mg/dl [IQR:9.4–33.9], 21.1 mg/dl [IQR:11.7–34.9], and 5.0 mg/dl [IQR:2.7–8.1] in the FH-LDLR, FH-PCSK9, and CONTROL groups, respectively, P=0.002 for FH-LDLR vs. CONTROL, P=0.002 for FH-PCSK9 vs. CONTROL).Conclusions:These data demonstrate that serum Lp(a) is elevated in patients with FH caused by PCSK9 gain-of-function mutations to the same level as that in FH caused by LDLR mutations.

Background:No study has examined the association between television (TV) viewing time and mortality from stroke and coronary artery disease (CAD) in Japanese.Methods and Results:A total of 35,959 men and 49,940 women aged 40–79 years without a history of cardiovascular disease (CVD) and cancer were followed from 1988–1990 until 2009. During 19.2 median years of follow-up, there were 2,553 deaths from stroke, 1,206 from CAD and 5,835 from total CVD. Compared with viewing TV for <2 h/day, mortality from stroke, CAD and total CVD were higher for ≥6 h/day of TV viewing. The multivariable hazard ratios (HRs) for ≥6 h/day of TV viewing were 1.15 (95% confidence interval: 0.96–1.37) for stroke, 1.33 (1.03–1.72) for CAD and 1.19 (1.06–1.34) for total CVD. The corresponding HRs for each 1-h/day increment in TV viewing time were 1.01 (0.99–1.04), 1.04 (1.01–1.08) and 1.02 (1.01–1.04), respectively. The excess risk of mortality from CAD and total CVD was somewhat attenuated after further adjustment for potential mediators such as history of hypertension and diabetes: the multivariable HRs for ≥6 h/day of TV viewing were 1.24 (0.96–1.61) and 1.14 (1.02–1.28). The corresponding HRs for each 1-h/day increment in TV viewing time were 1.03 (1.00–1.07) and 1.01 (1.00–1.03).Conclusions:Prolonged TV viewing was associated with a small but significant increase in mortality from CAD and total CVD in Japanese.

Background:To clarify the effects of warfarin therapy in very old patients with non-valvular atrial fibrillation (NVAF), a post-hoc analysis was performed using the data of the J-RHYTHM Registry.Methods and Results:A consecutive series of AF outpatients was enrolled from 158 institutions. Of 7,937 patients, 7,406 with NVAF (men, 70.8%; 69.8±10.0 years) were followed for 2 years or until an event occurred. Patients were divided into 3 age groups (<70, 70–84, and ≥85 years) and 5 subgroups according to international normalized ratio (INR; <1.6, 1.6–1.99, 2.0–2.59, 2.6–2.99, and ≥3.0). Prevalence of female sex, permanent AF, hypertension, coronary artery disease, heart failure, and history of ischemic stroke/transient ischemic attack was higher in the older groups. In the oldest group, 79.7% of patients received warfarin and their time in therapeutic range, using the Japanese target INR of 1.6–2.6, was 67.1%. Rate of thromboembolic events was lower in the age groups <70 and 70–84 years (P=0.027 and P<0.001, respectively) for patients receiving warfarin compared with those who were not. In the oldest group, the rate of thromboembolism plus major hemorrhage was lower at INR 1.6–2.59.Conclusions:Warfarin could have beneficial effects even in very old NVAF patients if INR is kept between 1.6 and 2.59.

Background:Because the current Japanese guideline recommends CHADS2score-based risk stratification in nonvalvular atrial fibrillation (NVAF) patients and does not list female sex as a risk for thromboembolic events, we designed the present study to compare the CHA2DS2-VASc and CHA2DS2-VA scores in the J-RHYTHM Registry.Methods and Results:We prospectively assessed the incidence of thromboembolic events for 2 years in 997 NVAF patients without warfarin treatment (age 68±12 years, 294 females). The predictive value of the CHA2DS2-VASc and CHA2DS2-VA scores for thromboembolic events was evaluated by c-statistic difference and net reclassification improvement (NRI). Thromboembolic events occurred in 7/294 females (1.2%/year) and 23/703 males (1.6%/year) (odds ratio 0.72 for female to male, 95% confidence interval (CI) 0.28–1.62, P=0.44). No sex difference was found in patient groups stratified by CHA2DS2-VASc and CHA2DS2-VA scores. There were significant c-statistic difference (0.029, Z=2.3, P=0.02) and NRI (0.11, 95% CI 0.01–0.20, P=0.02), with the CHA2DS2-VA score being superior to the CHA2DS2-VASc score. In patients with CHA2DS2-VASc scores 0 and 1 (n=374), there were markedly significant c-statistic difference (0.053, Z=6.6, P<0.0001) and NRI (0.11, 95% CI 0.07–0.14, P<0.0001), again supporting superiority of CHA2DS2-VA to CHA2DS2-VASc score.Conclusions:In Japanese NVAF patients, the CHA2DS2-VA score, a risk scoring system excluding female sex from CHA2DS2-VASc, may be more useful in risk stratification for thromboembolic events than CHA2DS2-VASc score, especially in identifying truly low-risk patients.

Background:We explored 12-month clinical outcomes of 929 patients with atrial fibrillation (AF) undergoing percutaneous coronary intervention (PCI) with bare-metal stents (BMS) vs. drug-eluting stents (DES) from the prospective multicenter AFCAS (Atrial Fibrillation undergoing Coronary Artery Stenting) registry.Methods and Results:Endpoints included the first occurrence of major adverse cardiac and cerebrovascular events (MACCE), defined as a composite of all-cause death, myocardial infarction (MI), target vessel revascularization, definite/probable stent thrombosis (ST), transient ischemic attack or stroke. Bleeding events were defined according to the Bleeding Academic Research Consortium criteria. Altogether, 673 (72.4%) patients received BMS and 220 (23.7%) at least one DES. Patients treated with DES more often had diabetes and prior ischemic events, and a longer stent length (P<0.05 for all), whereas patients treated with BMS more often had heart failure and were more likely to present with acute ST-elevation MI (P<0.05 for both). At 12-month follow-up, rates and risks of MACCE and total bleeding events were comparable between the groups (22.0% with BMS vs. 19.5% with DES, P=0.51, hazard ratio (HR) 0.89, 95% confidence interval (CI) 0.63–1.25 for DES) and (19.5% vs. 15.0%, respectively, P=0.16, HR 0.75, 95% CI 0.51–1.09 for DES). Definite/probable ST was more frequent in the BMS group (1.9% vs. 0%, respectively, P=0.046).Conclusions:In real-world patients with AF undergoing PCI, DES use was associated with outcomes comparable to those with BMS without excess bleeding complications. More ST was seen in BMS-treated patients.

Background:The aim of this study was to investigate the incidence and predictors (which have not previously been fully elucidated) of late-phase thromboembolism (TE) after catheter ablation (CA) for paroxysmal atrial fibrillation (AF).Methods and Results:We studied 1,156 consecutive patients (61±10 years; 891 men; CHADS2score, 0.8±1.0) after CA for symptomatic paroxysmal AF and examined the details of late-phase TE. During a follow-up of 49.5±21.9 months (median, 47 months; range, 6–113 months) after CA, 9 patients (0.78%) developed late-phase TE, all of which were ischemic stroke. Of these, 5 patients with AF recurrence experienced cardioembolism; the AF was asymptomatic at recurrence. The remaining 4 without AF recurrence experienced cardioembolism (n=1), small-vessel occlusion (n=1), large-artery atherosclerosis (n=1), and stroke of other determined etiology (n=1). On Kaplan-Meier analysis patients with structural heart disease (P=0.003), AF recurrence after the final CA (P=0.01), prior stroke (P=0.002), CHADS2score ≥2 (P=0.0002), left ventricular ejection fraction <50% (P<0.0001), and spontaneous echo contrast on transesophageal echocardiogram (P=0.0004) had a significantly higher risk of late-phase TE. Multivariate analysis indicated that CHADS2score ≥2 (HR, 4.49; 95% CI: 1.08–22.56; P=0.04) independently predicted late-phase TE.Conclusions:The incidence of TE was low after CA for paroxysmal AF, but CHADS2score ≥2 independently increased the risk of late-phase TE.

Background Based on the NIPPON DATA80, risk charts for the probability of death from coronary heart disease (CHD), stroke, and all cardiovascular disease (CVD) were constructed by sex and 10-year age groups. Methods and Results The 9,638 participants were followed-up for 19 years from 1980, excluding 28 individuals without the necessary baseline data and 257 participants with past history of stroke or CHD. Final analysis was performed on 9,353 participants (4,098 men, mean age 50.3 years; 5,255 women, mean age 50.8) using a Cox proportional hazards model. Death probabilities over a 10-year period from CHD, stroke, and all CVD were calculated and displayed as color coding on each chart by combining 10-year age, systolic blood pressure, smoking, and serum total cholesterol and glucose levels. Six different colors corresponding to probabilities of death were displayed on each chart. Conclusions The original charts based on the findings from NIPPON DATA80 are suitable for assessing CHD, stroke, and all CVD death risk in the general Japanese population. These charts should be used as a health-education tool for lifestyle modification targeting individuals with CVD risk factors. (Circ J 2006; 70: 1249 - 1255)

Background: A prospective, 3-year comparative observational study compared the risk of cardiovascular events in patients with osteoarthritis or rheumatoid arthritis prescribed celecoxib or a nonsteroidal antiinflammatory drug (NSAID). Methods and Results: Patients prescribed celecoxib (n=5,470) or NSAIDs (n=5,059) between November 1, 2007, and July 31, 2008 in 1,084 hospitals and clinics in Japan were eligible for safety analysis. Mean (standard deviation) observation for the celecoxib group was 716 (420) days and 692 (426) days for the NSAID group (P=0.004). Composite I (adjudicated cardiovascular adverse events of myocardial infarction, angina pectoris, heart failure, cerebral infarction, cerebral hemorrhage) number of events (percentage) and rate/1,000 person years was 66 (1.2%) and 6.2 (10,745 person years), respectively, for the celecoxib and 65 (1.3%) and 6.8 (9,601 person years) for the NSAID (P=0.58) groups. Composite II (all cardiovascular events) number of events (percentage) and rate/1,000 person years was 79 (1.4%) and 7.4, respectively, for the celecoxib and 84 (1.7%) and 8.8 for the NSAID (P=0.26) group. Adjusted Cox hazards ratio (95% confidence interval) was 0.89 (0.63–1.27; P=0.52) for Composite I, 0.87 (0.63–1.19; P=0.39) for Composite II and 1.03 (0.75–1.41; P=0.87) for death from all causes. Conclusions: After adjustment for confounding variables, celecoxib was not associated with an increase of cardiovascular risk in comparison with nonselective NSAID in Japanese patients with rheumatoid arthritis or osteoarthritis in an observational setting.  (Circ J 2014; 78: 194–205)

Background: Although there is a general fear that exercise training might deteriorate renal function in chronic kidney disease (CKD) patients, the effect of cardiac rehabilitation (CR) on renal function in acute myocardial infarction (AMI) patients with CKD remains unknown. We sought to determine whether CR is associated with amelioration or deterioration of renal function in such patients. Methods and Results: We enrolled 528 AMI patients who participated in a 3-month CR program. Clinical data before and after CR were compared according to participation in CR and comorbidities. In patients without CKD (estimated glomerular filtration rate [eGFR] ≥60ml·min−1·1.73m−2, n=348), peak oxygen uptake (VO2) and B-type natriuretic peptide (BNP) improved without a change in eGFR. In contrast, in patients with CKD (eGFR <60ml·min−1·1.73m−2, n=180), eGFR improved (48±12 to 53±15ml·min−1·1.73m−2, P<0.001), together with improvements in peak VO2 and BNP. When patients with CKD were divided into non-active (≤1time/week, n=70) and active participants (≥1.1time/week, n=110) according to attendance in CR, active participants showed an improvement in eGFR (50±10 to 53±13ml·min−1·1.73m−2, P<0.001), whereas eGFR did not change in non-active participants. Similar results were obtained in each subgroup of patients with hypertension, dyslipidemia, or diabetes mellitus. Conclusions: In AMI patients with CKD, active participation in CR was associated with improved peak VO2, BNP, and eGFR.  (Circ J 2014; 78: 377–384)
