Background:Increased heart rate (HR) is an independent risk factor for cardiovascular outcomes in chronic heart failure (HF). Ivabradine, anIfinhibitor, improved outcomes in patients with HF and reduced ejection fraction (HFrEF) in the SHIFT study. We evaluated its efficacy and safety in Japanese HFrEF patients in a randomized, double-blind, placebo-controlled phase III study: the J-SHIFT study. The main objective was to confirm a hazard ratio of <1 in the primary composite endpoint of cardiovascular death or hospital admission for worsening HF.Methods and Results:Patients with NYHA functional class II–IV, left ventricular EF ≤35%, and resting HR ≥75 beats/min in sinus rhythm under optimal medical therapy received ivabradine (n=127) or placebo (n=127). Mean reduction in resting HR was significantly greater in the ivabradine group (15.2 vs. 6.1 beats/min, P<0.0001). However, symptomatic bradycardia did not occur. A total of 26 (20.5%) patients in the ivabradine group and 37 (29.1%) patients in the placebo group had the primary endpoint event (hazard ratio 0.67, 95% CI 0.40–1.11, P=0.1179) during median follow-up of 589 days. Mild phosphenes were reported in 8 (6.3%) patients in the ivabradine group and 4 (3.1%) patients in the placebo group (P=0.3760).Conclusions:The J-SHIFT study supported the efficacy and safety of ivabradine for Japanese HFrEF patients, in accord with the SHIFT study.

Background:The optimal cutoff values of the brachial-ankle pulse wave velocity (baPWV) for predicting cardiovascular disease (CVD) were examined in patients with hypertension.Methods and Results:A total of 7,656 participants were followed prospectively. The hazard ratio for the development of CVD increased significantly as the baPWV increased, independent of conventional risk factors. The receiver-operating characteristic curve analysis showed that the optimal cutoff values for predicting CVD was 18.3 m/s. This cutoff value significantly predicted THE incidence of CVD.Conclusions:The present analysis suggests that the optimal cutoff value for CVD in patients with hypertension is 18.3 m/s.

Aims: This prospective observational study, which utilized repeated annual measurements performed over a 9-year period, applied mixed model analyses to examine age-related differences in longitudinal associations between alcohol intake and arterial stiffness, pressure wave reflection, and inflammation.Methods: In 4016 middle-aged (43±9 years) healthy Japanese male employees, alcohol intake, brachial-ankle pulse wave velocity (baPWV), radial augmentation index (rAI), and serum C-reactive protein (CRP) levels were measured annually during a 9-year study period.Results: The estimated marginal mean baPWV (non-drinkers=1306 cm/s, mild–moderate drinkers=1311 cm/s, and heavy drinkers=1337 cm/s, P<0.01) and that of rAI showed significant stepped increases in an alcohol dose-dependent manner in the entire cohort, but an increase in rAI was not observed in subjects aged ≥ 50 years. The estimated slope of the annual increase in baPWV, but not rAI, was higher for heavy drinkers than for non-drinkers (slope difference, 1.84; P<0.05), especially for subjects aged <50 years (slope difference, 2.84; P<0.05).Conclusion: In middle-aged male Japanese employees, alcohol intake may attenuate inflammatory activity. While alcohol intake may exacerbate the progression of arterial stiffening in a dose-dependent manner without mediating inflammation, especially in subjects under 50 years of age, it may promote pressure wave reflection abnormalities with aging at earlier ages without further exacerbation at older ages.

Background:Papaverine is useful for evaluating the functional status of a coronary artery, but it may provoke malignant ventricular arrhythmia (VA). The aim of this study was to investigate the incidence, and clinical and ECG characteristics of patients with papaverine-induced VAs.Methods and Results:The 182 consecutive patients underwent fractional flow reserve (FFR) measurement of 277 lesions. FFR was determined after intracoronary papaverine administration by standard procedures. The clinical and ECG characteristics were compared between patients with and without ventricular tachycardia (VT: ≥3 successive premature ventricular beats (PVBs), or ventricular fibrillation (VF)). After papaverine administration, the QTc interval, QTUc interval, and T-peak to U-end interval were prolonged significantly. Single PVBs on the T-wave or U-wave type developed in 29 patients (15.9%). Polymorphic VT (torsade de pointes) occurred in 5 patients (2.8%), and of those, VF developed in 3 patients (1.7%). No clinical and baseline ECG parameters were predictors for VT or VF except for sex and administration of papaverine into the left coronary artery. Excessive prolongation of QT (or QTU), T-peak to U-end intervals and giant T-U waves were found immediately prior to the ventricular tachyarrhythmias (VTAs), which were unpredictable from the baseline data.Conclusions:Intracoronary administration of papaverine induced fatal VTAs, although the incidence is rare. Excessive prolongation of the QT (and QTU) interval appeared prior to VTAs; however, they were unpredictable. (Circ J 2015; 79: 530–536)

Since 2001, brachial-ankle pulse wave velocity (brachial-ankle PWV) measurement has been applied for risk stratification of patients with atherosclerotic cardiovascular disease and/or its risk factors in Japan. Measurement of the brachial-ankle PWV is simple and well standardized, and its reproducibility and accuracy are acceptable. Several cross-sectional studies have demonstrated a significant correlation between the brachial-ankle PWV and known risk factors for cardiovascular disease; the correlation is stronger in subjects with cardiovascular disease than in those without cardiovascular disease. We conducted a meta-analysis, which demonstrated that the brachial-ankle PWV is an independent predictor of future cardiovascular events. Furthermore, the treatment of cardiovascular risk factors and lifestyle modifications have been shown to improve the brachial-ankle PWV. Thus, at present, brachial-ankle PWV is close to being considered as a useful marker in the management of atherosclerotic cardiovascular disease and/or its risk factors.

A 41-year-old man developed sustained monomorphic ventricular tachycardia (VT) with a left bundle branch block and inferior axis pattern during treadmill exercise concomitantly with unmasking of the typical Brugada electrocardiography (ECG) pattern. The typical ECG phenotype was provoked by a class IC drug. VT was not inducible with programmed electrical stimulation, but premature ventricular beat and non-sustained VT with the same morphology increased in frequency with isoproterenol treatment. Additionally, atrioventricular nodal reentrant tachycardia (AVNRT) was induced by electrical stimulation and VT and AVNRT were treated by radiofrequency catheter ablation.
