Upper-Arm SBP Decline Associated with Repeated Cuff-Oscillometric Inflation Significantly Correlated with the Arterial Stiffness Index.

We evaluated the clinical significance of the new non-invasive vascular indices to explore their potential utility using repeated cuff-oscillometric inflation. In 250 consecutive outpatients, we performed a cross-sectional, retrospective, single-center, observational study to investigate sequential differences in arterial stiffness using blood pressure, arterial velocity pulse index (AVI), and arterial pressure volume index (API) with repeated measurements. Males accounted for 62.

Rationale and Design of the Orencia Atherosclerosis and Rheumatoid Arthritis Study (ORACLE Arthritis Study): Implications of Biologics against Rheumatoid Arthritis and the Vascular Complications, Subclinical Atherosclerosis.

To explore the biological and immunological basis of human rheumatoid arthritis and human atherosclerosis, we planned and reported a detailed design and rationale for Orencia Atherosclerosis and Rheumatoid Arthritis Study (ORACLE Arthritis Study) using highly sensitive, high-throughput, human autoantibody measurement methods with cell-free protein synthesis technologies. Our previous study revealed that subjects with atherosclerosis had various autoantibodies in their sera, and the titers of anti-Th2 cytokine antibodies were correlated with the severity of atherosclerosis. Because rheumatoid arthritis is a representative autoimmune disease, we hypothesized that both rheumatoid arthritis and atherosclerosis are commonly developed by autoantibody-mediated autoimmune processes, leading to incessant inflammatory changes in both articular joint tissues and vessel walls.

The Types and Proportions of Commensal Microbiota Have a Predictive Value in Coronary Heart Disease.

Previous clinical studies have suggested that commensal microbiota play an important role in atherosclerotic cardiovascular disease; however, a synthetic analysis of coronary heart disease (CHD) has yet to be performed. Therefore, we aimed to investigate the specific types of commensal microbiota associated with CHD by performing a systematic review of prospective observational studies that have assessed associations between commensal microbiota and CHD. Of the 544 published articles identified in the initial search, 16 publications with data from 16 cohort studies (2210 patients) were included in the analysis.

Gut microbiota and atherosclerosis: role of B cell for atherosclerosis focusing on the gut-immune-B2 cell axis.

Atherosclerosis is the leading cause of cardiovascular mortality and morbidity worldwide and is described as a complex disease involving several different cell types and their molecular products. Recent studies have revealed that atherosclerosis arises from a systemic inflammatory process, including the accumulation and activities of various immune cells. However, the immune system is a complicated network made up of many cell types, hundreds of bioactive cytokines, and millions of different antigens, making it challenging to readily define the associated mechanism of atherosclerosis.

Lubiprostone as a potential therapeutic agent to improve intestinal permeability and prevent the development of atherosclerosis in apolipoprotein E-deficient mice.

The interaction between atherosclerosis and commensal microbes through leaky gut syndrome (LGS), which is characterized by impaired intestinal permeability and the introduction of undesired pathogens into the body, has not been fully elucidated. Our aim was to investigate the potential role of a ClC-2 chloride channel activator, lubiprostone, which is reported to have beneficial effects on LGS, in the development of atherosclerosis in apolipoprotein E-deficient (ApoE-/-) mice. After a 15-week feeding period of a Western diet (WD), ApoE-/- mice were treated with a Western-type diet (WD) alone or WD with oral supplementation of lubiprostone for 10 weeks.

Comparison of anti-inflammatory effects of rivaroxaban vs. dabigatran in patients with non-valvular atrial fibrillation (RIVAL-AF study): multicenter randomized study.

Some experimental studies have shown that direct oral anticoagulants (DOACs) have anti-inflammatory effects. However, the interval changes in inflammatory markers in patients with non-valvular atrial fibrillation (AF) who receive DOACs remain unknown. Between July 2013 and April 2014, a total of 187 AF patients randomly assigned to receive rivaroxaban (n = 91) or dabigatran (n = 96) were assessed for eligibility.

Takotsubo Cardiomyopathy in a Patient with Previously Undiagnosed Hypertrophic Cardiomyopathy with Latent Obstruction.

A 62-year-old woman with takotsubo cardiomyopathy (TCM) accompanied by cardiogenic shock due to the obstruction of left ventricular outflow tract (LVOT) and massive mitral regurgitation (MR) was admitted to the emergency department. After successful treatment with intensive care, dobutamine stress-echocardiography was performed, which reproduced a dynamic LVOT gradient, severe MR and cardiogenic shock. A histological examination obtained from the right ventricular septum demonstrated hypertrophied and bizarre myocytes, with myocyte disarray.

Impact of flow-mediated dilatation and coronary calcification in providing complementary information on the severity of coronary artery disease.

Background And Aims: Endothelial dysfunction and coronary artery calcification (CAC) may represent two distinct and separate processes in the development of coronary atherosclerosis. However, the interaction between these factors in determining the development of coronary artery disease (CAD) is uncertain.

Methods: Brachial artery flow-mediated dilatation (FMD) was measured by high-resolution ultrasound before coronary angiography, in 156 patients undergoing coronary CT angiography on suspicion of CAD (M/F 100/56, age 67 ± 11yrs).

Pulmonary Thromboembolism Caused by Prolonged Compression at the Femoral Access Site and a Venous Aneurysm of the Ipsilateral Popliteal Vein.

A 51-year-old female with dilated cardiomyopathy underwent a cardiac catheterization via right common femoral vein and artery. Prolonged compression with a bandage and extension of supine bed rest were needed. Immediately after standing up, she lost consciousness and developed electromechanical dissociation.

Impact of n-3 polyunsaturated fatty acids in predicting ischemia/reperfusion injury and progression of myocardial damage after reperfusion in patients with ST-segment elevation acute myocardial infarction.

Background: In animal models of acute myocardial infarction, n-3 polyunsaturated fatty acids (PUFAs) administered before coronary occlusion have been suggested to prevent induction of ventricular arrhythmia and limit infarct size. However, the relation between the serum levels of n-3 PUFAs and ischemia/reperfusion (I/R) injury remains unclear.

Methods: 211 patients with ST-segment elevation acute myocardial infarction received emergency percutaneous coronary intervention (PCI) within 6h from the onset.
