Acute pulmonary embolism (PE) is the third cause of cardiovascular (CV) mortality. We evaluated a new risk index, named Age-Mean Arterial Pressure Index (AMAPI), to predict 30-day CV mortality in patients with acute PE. Data of 209 patients (44.0% male and 56.0% female, mean age 70.58 ± 14.14 years) with confirmed acute PE were retrospectively analysed. AMAPI was calculated as the ratio between age and mean arterial pressure (MAP), which was defined as [systolic blood pressure + (2 × diastolic blood pressure)]/3...

Left ventricular (LV) properties in hypertension (HTN) could be deteriorated by pressure overload, especially in endocardium, resulting in hypertensive heart failure (HHF). We sought to noninvasively examine LV systolic and diastolic functions at three myocardial layers in HTN and elucidate features of HHF by speckle-tracking echocardiography (STE) with high volume rates. We examined normotensive controls (n = 54), HTN patients without LV hypertrophy (LVH) (n = 50), and HTN patients with LVH (n = 40) and HHF patients (n = 45)...

Assessment of left ventricular (LV) dysfunction is vital in patients with repaired tetralogy of Fallot (rTOF). The early diastolic intraventricular pressure gradient (IVPG) in the LV plays an important role in diastolic function. IVPG is calculated as the intraventricular pressure difference divided by the LV length, which allows to account for differences in LV size and therefore calculate IVPG in children. We aimed to investigate the mechanisms of LV diastolic dysfunction by measuring mid-to-apical IVPG as an indicator of the active suction force sucking blood from the left atrium into the LV...

Atrial fibrillation (AF) is one of the most common cardiac arrhythmias, and carries an increased risk of cardiogenic embolism. Oral anticoagulants (OACs) including warfarin and/or non-vitamin K antagonists can prevent the majority of these events. The Saitama AF Registry was a community-based survey of patients with AF in Saitama City, which represents an urban community in Japan. A total of 75 institutions participated in the registry and attempted to enroll consecutive patients with AF from September 2014 to August 2015...

The long-term outcome is poor in patients with sleep apnea and cardiovascular disease. Polyunsaturated fatty acid (PUFA) is also known as an independent predictor for adverse clinical events. However, the profile of PUFA in sleep apnea patients with coronary artery disease (CAD) is still unclear. This study aimed to clarify the association between sleep apnea and PUFA profiles in patients with CAD. Two hundred seventy-four consecutive patients undergoing percutaneous coronary intervention (PCI) were screened for sleep apnea using nocturnal oximetry...

Atrial fibrillation (AF) itself creates structural and electrophysiological changes such as atrial enlargement, shortening of refractory period and decrease in conduction velocity, called "atrial remodeling", promoting its persistence. Although the remodeling process is considered to be reversible, it has not been elucidated in detail. The aim of this study was to assess the feasibility of P wave dispersion in the assessment of reverse atrial remodeling following catheter ablation of AF. Consecutive 126 patients (88 males, age 63...

Coronary heart disease is associated with high morbidity and mortality. Endothelial dysfunction in affected patients is linked to long-term atherosclerotic disease progression and cardiovascular event rates. The present paper reports on changes in the levels of endothelial progenitor cells (VEGFR2/CD133/CD34), essential for endothelial repair, and of endothelial microvesicles (CD31/annexin V) as indicators of endothelial lesion, in patients undergoing coronary bypass surgery with respect both to baseline levels and to counts in healthy subjects...

Although there is reportedly seasonal variation in the occurrence of Takotsubo syndrome (TTS), it is unknown whether there is a relationship between season and patient characteristics, or whether season influences outcomes. Using the Diagnosis Procedure Combination database in Japan, we retrospectively identified 4306 patients (mean age 73.6 years) hospitalized with TTS between January 2011 and December 2013. We divided patients into four groups according to season of admission [n = 914, Spring (March-May); n = 1243, Summer (June-August); n = 1245, Autumn (September-November); n = 904, Winter (December-February)]...

The prognostic significance of chronic medical illness in comatose survivors of cardiac arrest who undergo targeted temperature management (TTM) remains largely unknown. We sought to assess the association between overall burden of pre-existing medical comorbidity and neurological outcomes in survivors of cardiac arrest undergoing TTM. We analyzed a prospectively collected cohort of 314 patients treated with TTM following cardiac arrest at a tertiary care hospital between 2007 and 2014. Overall burden of medical comorbidity was approximated with the use of the Charlson Comorbidity Index (CCI)...

Serum levels of the soluble urokinase-type plasminogen activator receptor (suPAR) reflect immune and inflammatory activation, and are shown to be associated with cardiovascular outcomes. We herein investigated the potential association between suPAR and left ventricular diastolic dysfunction among patients with preserved left ventricular ejection fraction (LVEF) and sinus rhythm. Among 291 patients who had sinus rhythm and an LVEF of ≥50% enrolled in the study, 26 (8.9%) were considered to have diastolic dysfunction...

The objective of the study was to clarify whether controlling nutritional status (CONUT) is useful for predicting the long-term prognosis of patients hospitalized with heart failure (HF). A total of 482 (57.5%) HF patients from the Ibaraki Cardiovascular Assessment Study-HF (N = 838) were enrolled (298 men, 71.7 ± 13.6 years). At admission, blood samples were collected and nutritional status assessed using CONUT. CONUT scores were defined as follows: 0-1, normal; 2-4, light; 5-8, moderate; and 9-12, severe undernutrition...

Osteoprotegerin (OPG) and receptor activator of nuclear factor-κB ligand (RANKL) are regulators of bone remodeling, but are also considered to play important roles in coronary artery disease (CAD). This study evaluated potential associations of soluble (s) RANKL and OPG with atherosclerosis-relevant cytokines. Blood was collected from 414 individuals who presented to our hospital with intermediate likelihood for CAD for further examination. Plasma concentrations of total sRANKL, OPG, and 20 cytokines were measured using sandwich-type enzyme-linked immunoassays (ELISAs; OPG and sRANKL) and Luminex laser-based fluorescence analysis and correlated with each other...

Peripheral arterial disease (PAD) is a common manifestation of arterial stenosis of the extremity that reduces arterial flow. While patients with periodontitis are at a high risk of PAD, little causal information has been provided to date. To clarify the relationship, we conducted this cross-sectional study. The oral condition of patients with or without PAD, who attended Tokyo Medical and Dental University Hospital, was evaluated. Blood examinations and dental clinical measurements, including number of teeth, probing pocket depth (PPD), bleeding on probing (BOP) and clinical attachment level (CAL) were performed...

We aimed to create a scoring model to predict post-discharge bleeding (PDB) after drug-eluting stent (DES) implantation in Japanese subjects. We enrolled 1912 consecutive patients undergoing DES implantation (age 70 ± 10 years; 72% male). PDB was defined as a composite of type 5, 3, and 2 bleeding using the Bleeding Academic Research Consortium criteria. A Cox proportional hazard model assessed predictors, and we then derived a clinical model stratifying risk of PDB after DES implantation. Ninety-eight patients (6...

Cardiopulmonary exercise testing (CPET) is useful for the evaluation of patients with suspected or confirmed pulmonary hypertension (PH). End-tidal carbon dioxide pressure (PETCO2) during exercise is reduced with elevated pulmonary artery pressure. However, the utility of ventilatory parameters such as CPET for detecting PH remains unclear. We conducted a review in 155 patients who underwent right heart catheterization and CPET. Fifty-nine patients had PH [mean pulmonary arterial pressure (mPAP) ≥25 mmHg]...

Transcatheter aortic valve implantation (TAVI) is recommended for patients who are inoperable or at high risk for surgical aortic valve replacement (SAVR). Corticosteroid therapy is considered to be a risk factor for SAVR, but there is a paucity of information about TAVI in patients taking corticosteroids. The aim of this study is to elucidate the outcome of TAVI in patients on chronic corticosteroid therapy, compared with SAVR. We retrospectively analyzed patients on corticosteroid therapy who underwent TAVI (n = 21) or SAVR (n = 30) for severe aortic stenosis in Sakakibara Heart Institute...

Although measurement of right ventricular ejection fraction (RVEF) may be relevant for evaluation of therapeutic efficacy and/or prognosis in patients with pulmonary hypertension, RVEF obtained by echocardiography has limited accuracy. In contrast, radionuclide and/or magnetic resonance imaging can measure RVEF more reliably. In this study, we investigated the relationship between RVEF measured by radionuclide angiography and the echocardiographic parameters that are recommended by the American Society of Echocardiography as representative of right heart function...
