BACKGROUND: Exercise therapy following endovascular treatment (EVT) is important for patients with peripheral artery disease (PAD); however, continuous exercise therapy is difficult to be performed in clinical practice. This study aimed to investigate the association between the implementation of home-based exercise using pedometers after EVT and 1-year clinical outcomes. METHODS: This multicenter observational prospective cohort registry included patients with PAD complaining of intermittent claudication who underwent EVT for aortoiliac and/or femoropopliteal artery lesions between January 2016 and March 2019. Patients were instructed to perform home-based exercises using a specific pedometer after EVT. The study population was divided into good and poor recording groups according to the frequency of the pedometer measurements. The good recording group was defined as those who completed ≥50 % of the prescribed daily pedometer recording during the follow-up period. The poor recording group was defined as those with an inability to use a pedometer and/or who completed <50 % of the prescribed daily pedometer recordings. The primary outcome was 1-year major adverse events (MAE), defined as a composite of all-cause death, non-fatal myocardial infarction, non-fatal stroke, target vessel revascularization, and major amputation of the target limb. RESULTS: The mean age was 74.4 years; 78 % were male. A total of 623 lesions were analyzed (58.7 % aortoiliac, 41.3 % femoropopliteal). At 1 year, a lower cumulative incidence of MAE was observed in the good recording group compared to that in the poor recording group [10/233 (4.3 %) vs. 35/267 (13.7 %) patients, respectively; p < 0.001]. Multivariate Cox regression analysis showed that patients in the good recording group had a lower hazard ratio for 1-year MAE (0.33; 95 % confidence interval, 0.16-0.68; p = 0.004) than that in the poor recording group. CONCLUSIONS: Good self-recording of pedometer measurements was associated with favorable prognosis in patients with PAD following EVT.

Sodium-glucose cotransporter 2 inhibitors could reduce cardiovascular events in patients with heart failure irrespective of diabetes status. In this prespecified sub-analysis of randomised-controlled trial, we investigated the efficacy of luseogliflozin (2.5 mg daily), a sodium-glucose cotransporter 2 inhibitor, with that of voglibose (0.6 mg daily), an alpha-glucosidase inhibitor, on high-risk lipid profile and inflammatory markers in patients with type-2 diabetes and heart failure. Among the 157 patients studied, there were no significant differences in the mean malondialdehyde LDL or small-dense LDL cholesterol levels between the luseogliflozin and voglibose groups (percent change: 0.2% vs. - 0.6%, p = 0.93; - 1.7% vs. - 8.6%, p = 0.21) after 12 weeks in comparison to levels at the baseline. No significant difference was observed between the two groups in the adiponectin and high-sensitivity C-reactive protein levels after 12 weeks compared to the baseline levels (percent change, - 1.6% vs. - 4.0% and 22.5% vs. 10.0%; p = 0.52 and p = 0.55, respectively). In conclusion, in patients with type-2 diabetes and heart failure, compared to voglibose, luseogliflozin did not significantly improve the high-risk lipoprotein profile including malondialdehyde LDL and small-dense LDL cholesterol or the levels of inflammatory markers, including adiponectin and high-sensitivity C-reactive protein.Trial registration: Trial number: UMIN-CTR, UMIN000018395; Registered 23 July 2015; URL: https://www.umin.ac.jp/ctr/index.htm .

BACKGROUND: Perioperative atrial fibrillation (POAF) after non-cardiac surgery is a risk factor for cardiovascular events including stroke and death. The aim of this subanalysis of the MAMACARI study, a multicenter randomized control study on the effectiveness of a bisoprolol transdermal patch for prevention of perioperative myocardial injury in high-risk patients undergoing non-cardiac surgery, was to identify the predictors of POAF after non-cardiac surgery in high-risk patients and to determine changes in blood pressure and heart rate during bisoprolol patch administration in the perioperative period. METHODS AND RESULTS: Patients aged over 60 years with hypertension and a high revised cardiac risk index (≥2) who were scheduled to undergo non-cardiac surgery were randomly assigned to a bisoprolol patch group (n = 120) or a control group (n = 120). We divided the patients into two groups: patients with POAF (POAF group; n = 16) and patients without POAF (non-POAF group; n = 206). Multivariate analysis showed that bisoprolol patch therapy (OR: 0.30, 95% CI: 0.092-0.978) and surgery time of 250 min or more (OR: 4.99, 95% CI: 1.37-18.2) were independently associated with POAF. Although systolic blood pressure did not differ significantly between the two groups throughout the perioperative period, treatment with a bisoprolol patch significantly reduced heart rate throughout the perioperative period compared with that in the control group. CONCLUSIONS: Low dose of a bisoprolol patch in the perioperative period was effective for prevention of POAF after non-cardiac surgery in high-risk patients, while long surgery time was an independent risk factor for POAF. It is expected that low dose of a bisoprolol patch can prevent POAF without causing hypotension.

ABSTRACT: Peripheral arterial disease (PAD) is one of major vascular diseases which frequently coexists with coronary arterial disease and cerebrovascular disease. The patients with PAD have a poor prognosis when it progresses. A new blood pressure testing device enables to simultaneously measure brachial blood pressure (BP), central BP, and several vascular parameters, with easy and non-invasive, in a short time. Here, we aimed to evaluate these arterial stiffness parameters in patients with PAD.In this study, 243 consecutive patients who were suspected of having PAD and referred to our hospital from September 2016 to June 2019, were registered. Several parameters, such as brachial BP, central BP, aortic pulse wave velocity (aPWV), total vascular resistance (TVR), augmentation index (AI) and augmentation pressure (AP), were determined by Mobil-O-Graph. Ankle-brachial pressure index (ABI) was used to define PAD (ABI ≤ 0.9 as PAD). The relationship between PAD and central BP, aPWV, TVR, AI, or AP were investigated.One hundred sixty-two patients (67%) were categorized as the PAD group and 81 patients (33%) as the non-PAD group. In the PAD group, the systolic brachial BP and central systolic BP were significantly higher than those in the non-PAD group (138 ± 24 mmHg vs 131 ± 19 mmHg, P < .05, 125 ± 22 mmHg vs 119 ± 18 mmHg, P < .05, respectively). TVR, AI, and AP were significantly higher in the PAD group (1785 ± 379 dyn s/cm5 vs 1661 ± 317 dyn s/cm5, P < .05, 26.2 ± 13.0% vs 22.2 ± 13.3%, P < .05, 13.5 ± 9.4 mmHg vs 10.7 ± 7.2 mmHg, P < .05, respectively). No significant differences in diastolic BP, central diastolic BP, and aPWV were found between the groups. Multivariate logistic regression analysis revealed that PAD was significantly associated with TVR, AI, and AP (P < .05, respectively).TVR/AP/AI were significantly higher in the PAD group than in the non-PAD group.

BACKGROUND: Oxidized high-density lipoprotein (oxHDL), unlike native HDL, is characterized by reduced cholesterol efflux capability and anti-inflammatory properties. The ratio of oxHDL to apolipoprotein A-I (oxHDL/apoAI) is a possible marker of dysfunctional HDL. The aim of this study was to evaluate the association between oxHDL/apoAI and coronary plaque characteristics that increase the likelihood of cardiovascular events as determined by coronary computed tomography (CT) angiography. METHODS: A total of 297 patients (mean age; 67 years, men; 63%) who underwent coronary CT angiography for suspected stable coronary artery disease (CAD) were included. High-risk plaques (HRP) were defined by three characteristics: positive remodeling; low-density plaques; and spotty calcification. Significant stenosis was defined as a luminal narrowing of >70%. Serum concentrations of oxHDL were measured using an enzyme-linked immunosorbent assay. RESULTS: Patients with higher oxHDL/ApoAI showed significantly greater prevalence of HRP (p = 0.03) and significant stenosis (p < 0.01) compared with patients with low oxHDL/ ApoAI. The multivariate logistic analysis demonstrated that oxHDL/ApoAI significantly associated with the presence of HRP and significant coronary stenosis (p = 0.01 and < 0.01). In the follow-up study including 243 patients for a median period of 1.8 years, univariate cox regression analysis showed that oxHDL/ApoAI, HRP and significant stenosis were significant predictors of cardiovascular events. CONCLUSIONS: A high oxHDL/apoAI was associated with the presence of HRP and significant stenosis determined by coronary CT angiography, which can lead to cardiovascular events in patients with suspected stable CAD.

Background Effects of sodium-glucose cotransporter 2 inhibitors on reducing hospitalization for heart failure have been reported in randomized controlled trials, but their effects on patients with heart failure with preserved ejection fraction (HFpEF) are unknown. This study aimed to evaluate the drug efficacy of luseogliflozin, a sodium-glucose cotransporter 2 inhibitor, in patients with type 2 diabetes mellitus and HFpEF. Methods and Results We performed a multicenter, open-label, randomized, controlled trial for comparing luseogliflozin 2.5 mg once daily with voglibose 0.2 mg 3 times daily in patients with type 2 diabetes mellitus suffering from HFpEF (left ventricular ejection fraction >45% and BNP [B-type natriuretic peptide] concentrations ≥35 pg/mL) in a 1:1 randomization fashion. The primary outcome was the difference from baseline in BNP levels after 12 weeks of treatment between the 2 drugs. A total of 173 patients with diabetes mellitus and HFpEF were included. Of these, 83 patients were assigned to receive luseogliflozin and 82 to receive voglibose. There was no significant difference in the reduction in BNP concentrations after 12 weeks from baseline between the 2 groups. The ratio of the mean BNP value at week 12 to the baseline value was 0.79 in the luseogliflozin group and 0.87 in the voglibose group (percent change, -9.0% versus -1.9%; ratio of change with luseogliflozin versus voglibose, 0.93; 95% CI, 0.78-1.10; P=0.26). Conclusion In patients with type 2 diabetes mellitus and HFpEF, there is no significant difference in the degree of reduction in BNP concentrations after 12 weeks between luseogliflozin and voglibose.

BACKGROUND: The aim of this study was to evaluate the efficacy and safety of transdermal β-blocker patches, which offer stable blood concentration and easy availability during operation, for prevention of perioperative myocardial injury (PMI) in high-risk patients.Methods and Results:In this randomized controlled trial, patients aged >60 years with hypertension and high revised cardiac risk index (≥2) undergoing non-cardiac surgery were randomly assigned to a bisoprolol patch or control group. Primary efficacy outcome was incidence of PMI, defined as postoperative high-sensitivity cardiac troponin T (hs-cTnT) >0.014ng/mL and relative hs-cTnT change ≥20%. Secondary efficacy outcomes were number of cardiovascular events and 30-day mortality. From November 2014 to February 2019, 240 patients from 5 hospitals were enrolled in this study. The incidence of PMI was 35.7% in the bisoprolol patch group and 44.5% in the control group (P=0.18). Incidence of major adverse cardiac events including non-critical myocardial infarction, strokes, decompensated heart failure and tachyarrhythmia was similar between the 2 groups. Tachyarrhythmia tended to be higher in the control group. There were no significant differences in safety outcomes including significant hypotension and bradycardia requiring any treatment between the 2 groups. CONCLUSIONS: Bisoprolol patches do not influence the incidence of PMI and cardiovascular events in high-risk patients undergoing non-cardiac surgery, but perioperative use of these patches is safe.

Recent large clinical trials failed to show clear benefits of percutaneous transluminal renal angioplasty (PTRA) as compared with medical therapy on patients with renal artery stenosis. It was also reported that proteinuria is an adverse prognostic factor after PTRA, and PTRA is less effective in patients with overt proteinuria. From the renoprotective point of view, to reduce proteinuria after PTRA is an important therapeutic goal in patients with renal artery stenosis with overt proteinuria. We hereby describe two patients successfully treated by combination therapy with PTRA and administration of angiotensin-converting enzyme (ACE) inhibitor for bilateral renal artery disease with overt proteinuria.

PURPOSE OF REVIEW: To summarize the current status of coronary computed tomography angiography (CTA) in the assessment of coronary plaques and discuss the ability of serial coronary CTA to quantitatively measure changes in the plaque burden in response to lipid-lowering therapy. RECENT FINDINGS: Recent advances in coronary CTA have allowed identification of high-risk coronary features in acute coronary syndrome and measurement of changes in the coronary plaque burden with good reproducibility. Statin therapy may delay plaque progression and change some plaque features. However, the clinical relevance of quantitative changes in coronary plaques and the optimal methods to reduce the plaque burden remain unclear. Despite guideline-directed lipid-lowering therapy, adverse events still occur in substantial numbers of patients receiving statins. Coronary CTA is noninvasive and has high diagnostic performance in patients with coronary artery disease, making change in the plaque burden an applicable biomarker for individualized assessment of future risk.

BACKGROUND: High-sensitivity cardiac troponin T (hs-cTnT) is useful for detecting myocardial injury and is expected to become a prognostic marker in patients undergoing non-cardiac surgery. The aim of this pilot study evaluating the efficacy of β-blocker therapy in a perioperative setting (MAMACARI study) was to assess perioperative myocardial injury (PMI) in elderly patients with preserved ejection fraction (EF) undergoing non-cardiac surgery.Methods and Results:In this prospective observational cohort study of 151 consecutive patients with preserved EF and aged >60 years who underwent non-cardiac surgery, serum levels of hs-cTnT were measured before and on postoperative days 1 and 3 after surgery. PMI was defined as postoperative hs-cTnT >0.014 ng/mL and relative hs-cTnT change ≥20%. A total of 36 (23.8%) of the patients were diagnosed as having PMI. The incidence of a composite of cardiovascular events within 30 days after surgery, including myocardial infarction, stroke, worsening heart failure, atrial fibrillation and pulmonary embolism, was significantly higher in patients with PMI than in patients without PMI (odds ratio (OR) 9.25, P<0.001, 95% confidence interval (CI) 2.65-32.3). Multivariate analysis revealed that left ventricular diastolic dysfunction defined by echocardiography was independently associated with PMI (OR: 3.029, 95% CI: 1.341-6.84, P=0.008). CONCLUSIONS: PMI is frequently observed in elderly patients undergoing non-cardiac surgery. Diastolic dysfunction is an independent predictor of PMI.

BACKGROUND: Recent clinical trials have demonstrated the efficacy of short-term treatment with tolvaptan, an oral vasopressin V2 receptor antagonist, in patients with heart failure. However, the response to tolvaptan varies among patients. The aim of this study was to determine factors associated with response to tolvaptan in patients with acute decompensated heart failure (ADHF). METHODS: The Tolvaptan Registry, a prospective, observational, multicenter cohort study performed in Japan, aims to determine factors affecting the responsiveness of tolvaptan in patients with ADHF. We enrolled ADHF patients treated with tolvaptan and they were divided into two groups: responders and non-responders. Responders were defined as subjects who met all of the following three conditions: (1) increasing urine volume during a 24-hour period after the start of tolvaptan treatment; (2) improvement in New York Heart Association functional class; and (3) decrease in cardiothoracic ratio assessed by chest X-ray on day 3 of tolvaptan administration. RESULTS: Among the 114 patients, treatment with tolvaptan improved three conditions of heart failure in more than half of all the cohorts (71 patients, 62%). As for baseline characteristics, estimated glomerular filtration rate, urine osmolality, and kidney size were significantly greater in responders than in non-responders. Multivariate logistic analysis revealed that kidney size was independently associated with responders (odds ratio: 1.083, p=0.001, 95% confidence interval 1.031-1.137). CONCLUSIONS: The main clinical characteristic of responders to treatment with tolvaptan is that kidney size is preserved.

Dual antiplatelet therapy (DAPT) after percutaneous coronary intervention increases the risk of bleeding. We studied the safety and clinical outcomes of switching from DAPT to aspirin monotherapy at 3 months after ZES implantation. We retrospectively evaluated 168 consecutive patients with coronary artery disease who had been implanted with a ZES from June 2009 through March 2010. After excluding 40 patients according to exclusion criteria such as myocardial infarction, 128 patients were divided into a 3-month DAPT group (67 patients, 88 lesions) and a 12-month conventional DAPT group (61 patients, 81 lesions). Coronary angiographic followup and clinical followup were conducted at more than 8 months and at 12 months after ZES implantation, respectively. Minor and major bleeding events, stent thrombosis (ST), and major adverse cardiac events (MACE) (death, myocardial infarction, cerebrovascular accident, target lesion revascularization, and target vessel revascularization) were evaluated. There were no statistically significant differences in the incidences of ST and MACE between the two groups. The incidence of bleeding events was significantly lower in the 3-month group than in the 12-month group (1.5% versus 11.5%, P < 0.05). DAPT can be safely discontinued at 3 months after ZES implantation, which reduces bleeding risk.

A 54-year-old man with a surgically repaired double-outlet right ventricle (DORV) presented with palpitations and worsening right heart failure. His 12-lead ECG showed atrial tachycardia (AT) with an atrial cycle length (CL) of 300 ms and an inverted saw-tooth F-wave pattern in the inferior leads II, III, and aVF typical of atrial flutter. Electrophysiological study and radiofrequency catheter ablation were performed. A total of 3 sustained ATs (AT1-AT3) were induced. Using the electroanatomical mapping system, CARTO3, and conventional mapping techniques, the ATs were identified as macroreentrant tachycardias circling around an incisional line on the free wall of the right atrium (AT1), the tricuspid annulus (AT2), and low voltage area in the lateral wall including the right septum (AT3). Accuracy of CARTO3 in three-dimensional reconstruction was sufficient to elucidate anatomical features (including catheter sites, incision, and low voltage areas) and macroreentrant circuits. However, conventional mapping techniques were also necessary to identify the mechanism of the tachycardias, and therefore to eliminate all of them successfully. This case demonstrates that the use of combined conventional and electroanatomical mapping techniques, such as CARTO3, can be helpful in identifying the critical isthmus for catheter ablation of macroreentrant AT in patients with surgically corrected congenital heart disease (CHD). © 2012 Japanese Heart Rhythm Society.

Background: To examine the effect of pacing sites on heart failure, we evaluated the brain natriuretic peptide (BNP) level and hospitalizations for heart failure. Methods: A total of 90 patients (mean age 77±9 years, 43 men) with newly implanted pacemakers (sick sinus syndrome, n = 21
atrioventricular block, n = 69) were divided into two groups according to the pacing site: RV apical pacing group (RVA group, n = 46) and RV septal pacing group (RVS group, n = 44). All patients had a preserved LV function and more than a 90% cumulative percent ventricular pacing. We performed BNP measurements annually and at the clinical follow-ups (mean duration 3.0 years). Results: Compared with the RVS group, in the RVA group the QRS duration was prolonged (162±14ms vs. 147± 17ms, p&lt
0.05). However, there was no significant difference in the BNP levels at 1 year (141±141pg/mL vs. 119±139pg/mL, p=NS) and δ BNP, the difference in the BNP levels between post-implantation and 1 year (-29 ±103pg/mL vs. 0±107pg/mL, p=NS). For hospitalization for heart failure, there was no significant difference between the groups (4.4% vs. 6.8%, p=NS). Conclusions: In patients with a preserved LV function, RVS or RVA pacing sites might not correlate with the heart failure. © 2011, Japanese Heart Rhythm Society. All rights reserved.

Background: Cardiac resynchronization therapy (CRT) is effective in many symptomatic patients with wide QRS complexes. However, whether CRT is effective in patients with narrow QRS complexes and dyssynchrony is unknown. We evaluated the efficacy of CRT in patients with narrow QRS complexes who were evaluated using real time three-dimensional echocardiography (RT3DE) before the implant. Method and Results: In a total of 18 out of 34 patients, we evaluated the mechanical dyssynchrony using 2D echocardiography and RT3DE. LV dyssynchrony was defined as a standard deviation of the time to reach the minimum systolic volume in 16 LV segments, expressed as the percentage of the cardiac cycle (systolic dyssynchrony index, SDI). A positive response to CRT was defined as a persistent reduction in the NYHA class during the long-term follow-up. An SDI score in the upper 10% was positive. Fourteen of 18 patients (78%) were responders. Six of 14 patients had narrow QRS complexes (QRS duration &lt
130ms). There was no significant difference in the SDI before the CRT implantation between the patients with narrow or wide QRS complexes (SDI: narrow 11.9±4.1% vs. wide 8.9±3.8%, p=0.09). Conclusion: The evaluation of the dyssynchrony using RT3DE might be useful to decide indication for CRT in patients with a narrow QRS complex. © 2011, Japanese Heart Rhythm Society.

We describe a case of a ventricular fibrillation (VF) storm related to a prominent and widely distributed J-wave. A 34-year-old man, without any family history of sudden cardiac death or structural heart disease, suffered from a VF storm unresponsive to repeated defibrillation attempts and drugs including amiodarone. After the VF disappeared, his electrocardiogram (ECG) exhibited prominent J-waves and ST-segment elevation in almost all the leads. The J-point elevation slowly decreased without any recurrence of VF within a few days, and finally the J-waves remained only in the inferolateral leads. In the electrophysiological study, we tried to record an epicardial electrogram from the coronary sinus on the lateral wall, but no definite delayed potentials were observed. After implanting an implantable cardioverter-defibrillator, we performed pharmacologic stress tests (pilsicainide, protanol, mexan and atropine). The J-waves increased only during bradycardia after administering mexan. In the Holter ECG, transient ST-segment elevation was repetitively observed only while asleep.With the J-wave syndrome, it has been suggested that autonomic tone plays a major role in the J-wave variability. In this case, prominent J-waves and ST-segment elevation were observed during bradycardia and sleep. This is a very rare case of J-wave syndrome with transient J-wave changes suggesting some relationship to the autonomic tone. © 2011, Japanese Heart Rhythm Society. All rights reserved.

84歳男。拡張型心筋症、慢性心不全で外来通院中で、慢性心不全の増悪にて入退院をくり返した。呼吸困難が悪化したため救急車にて搬送となった。拡張型心筋症を基礎心疾患とした慢性心不全の増悪と診断した。入院後、内服利尿薬は継続し、トルバプタンを追加した。投与開始4時間後から250mL/時を超える利尿が得られた。投与開始16時間後、血清Na濃度が増加し、口渇の訴えも認めたため飲水制限を緩和した。投与2日目には5330mL/日と著明な利尿が得られ、心不全徴候も改善したため飲水制限を中止とし、5%ブドウ糖液の点滴を追加した。投与7日目の胸部レントゲンにて、うっ血および心拡大の改善を認めた。投与11日目に軽快退院した。退院後トルバプタンを2週間だけ継続したが、中止1ヵ月後の外来受診時に心不全の増悪を認めたためフロセミドを増量した。現在まで心不全増悪による入院には至っていないが、血清Crが上昇傾向にある。
