We have previously reported that a long-acting loop diuretic, azosemide, reduces cardiovascular risks in patients with chronic heart failure (CHF) as compared with a short-acting one, furosemide, in Japanese Multicenter Evaluation of LOng- versus short-acting Diuretics In Congestive heart failure (J-MELODIC). However, the mechanisms of the difference have not been elucidated. This study aimed to examine whether there is a difference in the reduction in plasma brain natriuretic peptide (BNP) level and in left ventricular (LV) functional recovery between the CHF patients treated with the long-acting diuretic (the azosemide group) and the short-acting diuretic (the furosemide group)...

MicroRNAs are able to modulate gene expression in a range of diseases. We focused on microRNAs as potential contributors to the pathogenesis of ascending aorta (AA) dilatation in patients with stenotic tricuspid (TAV) or bicuspid aortic valve (BAV). Aortic specimens were collected from the 'concavity' and the 'convexity' of mildly dilated AAs and of normal AAs from heart transplant donors. Aortic RNA was analyzed through PCR arrays, profiling the expression of 84 microRNAs involved in cardiovascular disease...

Elevated right atrial (RA) pressure and progressive RA dilation are thought to play pivotal roles in the development of late complications after atriopulmonary connection (APC) Fontan surgery. However, no clear cut-off value for RA pressure or RA volume has been determined for stratifying the risk of developing Fontan complications. We hypothesized that RA tension, which incorporates information about both RA pressure and volume, might help predict the risk of developing complications. We retrospectively studied 51 consecutive APC Fontan patients (median postoperative period 14 years)...

The prognostic value of atrial fibrillation (AF) in heart failure with preserved ejection fraction (HFPEF) remains controversial. We sought to study the prognostic value of AF in a prospective cohort and to characterize the HFPEF patients with AF. KaRen was a prospective, multicenter, international, observational study intended to characterize HFPEF; 538 patients presenting with an acute decompensated cardiac failure and a left ventricular EF > 45% were included. EKG and echocardiogram performed 4-8 week following the index hospitalization were analyzed in core centers...

Previous studies have demonstrated that patients with small coronary artery lesions are at increased risk for late cardiac events after percutaneous coronary intervention. It remains uncertain whether second-generation drug-eluting stents have an advantage over first-generation drug-eluting stents in patients with small vessel lesions. Our aim was to compare in the 3-year clinical impact between second-generation everolimus-eluting stents (EES) and first-generation sirolimus-eluting stents (SES) in small vessel lesions...

Independently of the lipid-lowering effects, statin has been reported to attenuate the development of diabetic cardiomyopathy. However, the effect of statin in glucose-controlled diabetic condition has not been demonstrated. We evaluated the effect of fluvastatin on cardiac function, fibrosis, and angiotensin-converting enzyme-2 (ACE2) expression in glucose-controlled diabetic rats. Male Wistar rats were randomly divided into four groups: control (Group C), diabetes (Group D), diabetes with insulin (Group I), and diabetes with insulin and fluvastatin (Group I+F)...

: We aimed to investigate the safety and medium-term durability of an adjustable mitral annuloplasty ring in patients undergoing surgery for mitral valve regurgitation. Forty-five patients requiring mitral valve repair were enrolled into this prospective, multicentre study between May 2012 and May 2013 in six hospitals in Europe and Israel. Study endpoints evaluated the performance and safety of the device assessed using inter-individual comparisons. Implantation was performed through a sternotomy in ten patients and mini-thoracotomy in 35 patients...

Intracoronary acetylcholine (ACh) provocation test is useful to diagnose vasospastic angina. However, paroxysmal atrial fibrillation (AF) often occurs during intracoronary ACh provocation test, leading to disabling symptoms. The aim of this study was to investigate the incidence and predictors of paroxysmal AF during the test. A total of 377 patients without persistent AF who underwent intracoronary ACh provocation test were included. Paroxysmal AF during ACh provocation test was defined as documented AF on electrocardiogram during the procedure...

Overlapping implantation of bioresorbable vascular scaffolds is frequently necessary, but its influence on vessel and scaffold structure has not been thoroughly analyzed previously. The aim of this study was to analyze the acute effects of overlapping implantation on BRS as determined by optical coherence tomography (OCT). A total of 38 patients with de novo coronary artery stenoses who underwent OCT in the context of implantation of novolimus-eluting BRS (DESolve, Elixir Medical Corporation, Sunnyvale, California, USA) were investigated...

Left ventricular reverse remodeling (LVRR) is reported in dilated cardiomyopathy (DCM) patients (pts). However, numerous definitions of LVRR exist. Measurements of serum markers of fibrosis provide insight into myocardial fibrosis. The relationship between LVRR and fibrosis is poorly understood. From July 2014 until October 2015, we included 63 consecutive DCM pts (48 ± 12.1 years, EF 24.4 ± 7.4%) with completed baseline and 3-month follow-up echocardiograms. LVRR was assessed on the basis of four differing definitions...

We investigated the influence of tricuspid regurgitation (TR) severity on the echocardiographic peak systolic transtricuspid pressure gradient (TRPG) and evaluated the usefulness of the peak early diastolic transpulmonary valve pressure gradient (PRPG) for estimating pulmonary artery (PA) pressure. In 55 consecutive right heart-catheterized patients, we measured the peak systolic right ventricular (RV)-right atrial (RA) pressure gradient (RV-RACATH), peak early diastolic PA-RV pressure gradient (PA-RVCATH), and mean PA pressure (MPAPCATH)...

Coenzyme Q10 (CoQ10) has a potential role in the prevention and treatment of heart failure through improved cellular bioenergetics. In addition, it has antioxidant, free radical scavenging, and vasodilatory effects that may be beneficial. Although critical illness in intensive care unit is associated with decreased circulating CoQ10 levels, the clinical significance of CoQ10 levels during acute phase in the patients of cardiovascular disease remains unclear. We enrolled 257 consecutive cardiovascular patients admitted to the coronary care unit (CCU)...

We investigated the clinical situations and the present knowledge of Japanese cardiologists about coronary artery spasm before and after the establishment of guidelines for this condition in the real world. A questionnaire was developed regarding the number of cases of coronary angiography, percutaneous coronary intervention, and invasive/non-invasive spasm provocation tests before (2008) and after (2014) the establishment of the Japanese Circulation Society (JCS) guidelines for coronary artery spasm and the status of spasm provocation tests...

Statins are primarily metabolized by cytochrome P450 3A4 (CYP3A4), which reduces clopidogrel to its active metabolite. Recent studies suggest that CYP3A4-metabolized statins attenuate clopidogrel's anti-aggregatory effect on platelets. We aimed to assess the impact of concomitant CYP3A4-metabolized statin and clopidogrel use on antiplatelet activity and clinical outcomes in patients undergoing percutaneous coronary intervention (PCI). We enrolled 1187 patients from the HOST-ASSURE trial with platelet reactivity unit (PRU) values at both baseline and 1 month...

Although some studies have attempted to find useful prognostic factors in hypertrophic cardiomyopathy (HCM), those results are not fully helpful for use in actual clinical practice. Furthermore, several genetic abnormalities associated with HCM have been identified. However, the genotype-phenotype correlation in HCM remains to be elucidated. Here, we attempted to assess patients with different types of gene mutations causing HCM and investigate the prognosis. A total of 140 patients with HCM underwent a screening test for myofilament gene mutations by direct sequencing of eight sarcomeric genes...

Wild-type transthyretin amyloidosis (ATTRwt) is often overlooked in elderly patients with left ventricular hypertrophy (LVH). Impaired atrial function, in addition to ventricular diastolic dysfunction, is one of the hallmarks of cardiac amyloidosis. Here, we assessed the hypothesis that atrial function evaluated by A-velocity in pulse Doppler echocardiography is useful to differentiate ATTRwt in elderly patients with LVH. We analyzed 133 consecutive patients who underwent tissue biopsy to rule out infiltrative cardiomyopathy in our institute...

According to the Japanese Circulation Society guideline of vasospastic angina, incremental doses of acetylcholine (ACh) are prescribed for coronary spasm provocation: 20 and 50 μg for the right coronary artery (RCA), and 20, 50 and 100 μg for the left coronary artery (LCA). However, provocation by low doses of ACh in patients with low vasoreactivity may be less needed, and the requirement of 50 μg of ACh for the LCA in these patients has not been evaluated. In the present study, patients who underwent ACh provocation test for both the RCA and LCA were included...
