Unlabelled: In 2020, a 48-year-old male patient was admitted to our hospital due to unstable angina. In 2005, three first-generation sirolimus-eluting stents (1st-SESs) had been deployed to his right coronary artery (RCA). Over the past 10 years or so, the patient has been treated with single antiplatelet therapy using aspirin.

We recently reported increased serum OSM levels in patients with coronary artery disease. However, the specific role in HF with ischemic heart disease (IHD) remains unclear.

While no obvious coronary artery stenosis was found, there was evidence of apical ballooning wall motion in the left ventricle, leading to a diagnosis of takotsubo syndrome. Three months later, he occasionally experienced chest pain at rest, prompting us to conduct another cardiac catheterization.

However, cardiac complications of trastuzumab without left ventricular systolic dysfunction have been rarely reported. These include left bundle branch block, sinus node dysfunction, and ventricular tachycardia.

Our objective was to elucidate the electrical properties of the specific shape of LCPV and to apply it to an ablation procedure.
Methods And Results: We investigated consecutive 12 out of 204 paroxysmal AF patients who had the shape of a straight common trunk in LCPV defined by the formation of a single conduit with parallel cranial and caudal walls after the coalescence of superior and inferior PVs on the distal side.
We herein report a case of a 56-year-old woman with angina pectoris. She visited our emergency room because of chest pain. She finally underwent emergency percutaneous coronary intervention in right coronary artery due to acute coronary syndrome.
View Article and Find Full Text PDFObjective: Oncostatin M (OSM) is an inflammatory cytokine of the interleukin-6 family which plays a crucial role in the pathogenesis of atherosclerosis. Therefore, we tested our hypothesis that serum OSM levels are increased in patients with coronary artery diseases (CAD).
Methods And Results: Serum OSM level was measured by sandwich technique immunoassay in 315 consecutive patients and who underwent coronary angiography at the International University of Health and Welfare Hospital from April 2019 to March 2021.
Background: The impact of cold ambient temperature on out-of-hospital cardiac arrest (OHCA) in aged individuals caused by cardiovascular events in indoor environments has not been investigated sufficiently.
Methods and results: We conducted a case-crossover study. The relationship between OHCA caused by cardiovascular events and exposure to minimum temperature <0℃ was analyzed.
Aims: The study aims to evaluate the prognostic significance of impaired glucose tolerance (IGT) with reference to albuminuria in patients with chronic heart failure (CHF).
Methods And Results: We examined 535 CHF patients (mean 66 years, women 25%) in the control arm of our SUPPORT trial, in which we examined additive impact of olmesartan in hypertensive patients with symptomatic CHF treated with β-blockers and/or angiotensin-converting enzyme inhibitors. We examined the association between glycaemic abnormality (assessed by 75 g of oral glucose tolerance test) and albuminuria for a composite outcome of all-cause death, myocardial infarction, stroke, and HF hospitalization.
We present the case of an 82-year-old male patient with unstable angina pectoris referred for percutaneous coronary intervention in the saphenous vein graft (SVG) to left circumflex coronary artery. An everolimus-eluting cobalt chrome stent was successfully deployed, using an embolic protection device with balloon occlusion and aspiration system. During the procedure of aspiration thrombectomy, the deployed stent unexpectedly collapsed.

In this subanalysis study of the SUPPORT Trial, we addressed the influence of LVEF on the effects of olmesartan in HF.
Methods and results: Among 1,147 patients enrolled in the SUPPORT Trial, we examined 429 patients with reduced LVEF (HFrEF, LVEF <50%) and 709 with HFpEF (LVEF ≥50%).
We examined whether an additive treatment with an angiotensin receptor blocker, olmesartan, reduces the mortality and morbidity in hypertensive patients with chronic heart failure (CHF) treated with angiotensin-converting enzyme (ACE) inhibitors, β-blockers, or both. In this prospective, randomized, open-label, blinded endpoint study, a total of 1147 hypertensive patients with symptomatic CHF (mean age 66 years, 75% male) were randomized to the addition of olmesartan (n = 578) to baseline therapy vs. control (n = 569).

METHODS AND RESULTS: In the CHART-2 Study, we obtained information on daily life, physical ability, nutrition and mental status for 4,174 patients (mean age, 67.1±10.
View Article and Find Full Text PDFBackground: The appropriate target ranges of heart rate (HR) and systolic blood pressure (SBP) for the management of chronic heart failure (CHF) patients remain to be elucidated in a large-scale cohort study.
Methods And Results: We examined 3,029 consecutive CHF patients with sinus rhythm (SR) (mean age, 67.9 years) registered in the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 Study (CHART-2; NCT00418041).
Background: The prognostic impact of nutritional status is poorly understood in asymptomatic patients with structural and/or functional heart diseases, classified as stage B in the ESC/AHA/ACC chronic heart failure (HF) guidelines.
Methods And Results: We evaluated the impact of nutrition, using the controlling nutritional status (CONUT) score, calculated by the serum albumin and total cholesterol levels,and lymphocyte number, in 3,421 stage B patients from the Chronic Heart Failure Analysis and Registry in the Tohoku District-2 Study (mean age: 66.9±12.
Background: Although angiotensin receptor blockers (ARBs) are now one of the first-line drug classes for the management of hypertension, recommendations for the management of chronic heart failure (CHF) are limited. The supplemental benefit of angiotensin receptor blocker in hypertensive patients with stable heart failure using olmesartan (SUPPORT) trial investigates whether an additive treatment with an ARB, olmesartan, reduces the mortality and morbidity in hypertensive patients with stable chronic heart failure.
Methods And Results: The SUPPORT trial is a prospective randomized open-label blinded endpoint study.
Objective: The pleiotropic effects of 3-hydroxy-3-methylglutaryl-coenzyme A reductase inhibitors (statins) independent of cholesterol-lowering effects are thought to be mediated through inhibition of the Rho/Rho-kinase pathway. However, we have previously demonstrated that the pleiotropic effects of regular-dose statins are mediated mainly through inhibition of the Rac1 signaling pathway rather than the Rho/Rho-kinase pathway, although the molecular mechanisms of the selective inhibition of the Rac1 signaling pathway by regular-dose statins remain to be elucidated. In this study, we tested our hypothesis that small GTP-binding protein GDP dissociation stimulator (SmgGDS) plays a crucial role in the molecular mechanisms of the Rac1 signaling pathway inhibition by statins in endothelial cells.

The purpose of this study was to examine the prognostic impact of BUN changes during hospitalization on the long-term prognosis of AHFS patients.
Methods And Results: The Tohoku Acute Heart Failure Registry (n=497) is a multicenter retrospective cohort study enrolling AHFS patients who were admitted in 2007.
We describe a 42-year-old man with very late stent thrombosis (VLST) 35 months after implantation of a sirolimus-eluting stent (SES). Three months after the VLST episode, a follow-up angiography showed a formation of peri-stent coronary artery aneurysm. Sixty-five months after SES implantation, the patient suffered an out-of-hospital cardiac arrest.

The prognosis of patients with HF is still poor and a prospective approach for preventing and treating HF is necessary. The number of HF patients in Japan has been increasing since 1950 mainly because of a rapidly aging population.

Methods And Results: Nineteen healthy subjects (male/female 14/5; mean age, 31±3 [SD] years-old) were randomized to receive ezetimibe (10mg/day) or pravastatin (10mg/day) for 4 weeks in a cross-over manner with a 4-week washout interval.
