Associations between High-Density Lipoprotein Functionality and Major Adverse Cardiovascular Events in Patients Who Have Undergone Coronary Computed Tomography Angiography.

The present study aimed to investigate the associations between high-density lipoprotein (HDL) functionality and major adverse cardiovascular events (MACE) in patients who have undergone coronary computed tomography angiography (CCTA). We performed a prospective cohort study and enrolled 151 patients who underwent CCTA and had a follow-up of up to 5 years. We measured cholesterol efflux capacity (CEC), caspase-3/7 activity and monocyte chemoattractant protein-1 (MCP-1) secretion as bioassays of HDL functionality.

Associations Between High Levels of High-Density Lipoprotein Cholesterol and the Presence and Severity of Coronary Artery Disease in Patients Who Have Undergone Coronary Computed Tomography Angiography.

Background: Although a recent study in a Japanese cohort indicated that extremely high-density lipoprotein cholesterol (HDL-C, ≥ 90 mg/dL) had an adverse effect on atherosclerotic cardiovascular disease mortality, we could not conclude that high levels of HDL-C were associated with the presence or severity of coronary artery disease (CAD).

Methods: We enrolled 1,016 patients who were clinically suspected to have CAD and who underwent coronary computed tomography angiography (CCTA). The number of significantly stenosed coronary vessels (vessel disease (VD), ≥ 50% coronary stenosis is diagnosed as CAD) and the Gensini score were quantified using CCTA, and the lipid profile was measured.

Association between lipid profile and endothelial dysfunction as assessed by the reactive hyperemia index.

Introduction: We investigated the associations between endothelial dysfunction (ED) as evaluated by the reactive hyperemia index (RHI) obtained using Endo-PAT2000® and atherosclerotic risk factors in patients who underwent coronary artery angiography (CAG).

Methods: The subjects consisted of 191 patients who were clinically suspected to have CAD and underwent CAG, and in whom we could perform Endo-PAT2000®. We divided the patients into ED (RHI<1.

Associations between the psoas major muscle index and the presence and severity of coronary artery disease.

The associations between the presence and severity of coronary artery disease (CAD) and measurements of the psoas major muscle (PMM) as assessed by multidetector row coronary computed tomography angiography (MDCT) are not known.We enrolled 793 patients who were clinically suspected to have CAD or had at least one cardiac risk factor and had undergone MDCT. The number of significantly stenosed coronary vessels (VD) and measurements of the PMM index (PMMI) were determined using MDCT.

Regression and Stabilization of Coronary Vulnerable Plaque by Evolocumab as Assessed by Multidetector Row Computed Tomography.

A 65-year-old man was followed for his coronary conditions using 320-multi detector row computed tomography (MDCT) for 30 months. He had soft plaque in the right coronary artery (RCA) [mean density of plaque was 22 hounsfield units (HU)]. His initial serum low-density lipoprotein cholesterol (LDL-C) was 72 mg/dL.

Reactive Hyperemia Index Associated With Atherosclerotic Cardiovascular Disease Under Treatment for Lifestyle Diseases.

Background: Endothelial dysfunction is an early phase of atherosclerosis and causes atherosclerotic cardiovascular disease (ASCVD), but the cutoff reactive hyperemia index (RHI) for identifying ASCVD patients under treatment for lifestyle diseases is unknown.

Methods: Patients who visited Cardiology Section, Izumi General Medical Center, Kagoshima, Japan and were measured RHI using Endo-PAT 2000 during May 2014 and March 2016 were enrolled. We divided them into ASCVD and non-ASCVD groups and investigated the association with RHI between the groups.

Importance of measurement of the diameter of the distal radial artery in a distal radial approach from the anatomical snuffbox before coronary catheterization.

Coronary catheterization by a distal radial approach at the site of the anatomical snuffbox has recently been reported to be both safe and useful. No data are available on the diameter of the distal radial artery (DRA) in Japan, and it is unclear whether the DRA is large enough to withstand the insertion of a conventional sheath by a traditional radial approach. We enrolled 142 patients who underwent coronary catheterization and evaluated the vessel diameter of the DRA using ultrasound.

Randomized trial of an increased dose of calcium channel blocker or angiotensin II type 1 receptor blocker as an add-on intensive depressor therapy in type 2 diabetes mellitus patients with uncontrolled essential hypertension: the ACADEMIE Study.

There is a lack of data on how to treat hypertensive patients with diabetes when treatment with medium doses of calcium channel blocker and angiotensin II type 1 receptor blocker (ARB) is insufficient to achieve the target blood pressure (BP). A total of 121 participants with type 2 diabetes and uncontrolled essential hypertension, who were receiving medium doses of amlodipine (5 mg/day) and ARB, were enrolled. Participants were randomized to receive either a high dose of amlodipine (10 mg/day) plus a medium dose of ARB (high-AML) or a medium dose of amlodipine (5 mg/day) plus a high dose of ARB (high-ARB).

Efficacy and Safety of Combination Therapy Consisting of Angiotensin II Type 1 Receptor Blocker, Calcium Channel Blocker and Hydrochlorothiazide in Patients With Hypertension.

Background: Many patients continue to have high blood pressure (BP) even after treatment with high-dose (H)-angiotensin II type 1 receptor blocker (ARB)/calcium channel blocker (CCB) or middle-dose (M)-ARB/CCB/hydrochlorothiazide (HCTZ).

Methods: Thirty-two hypertensive patients who had the use of H-ARB/CCB or M-ARB/CCB/HCTZ were enrolled in this study. We applied a changeover with a switch to H-ARB (telmisartan 80 mg/day)/CCB (amlodipine 5 mg/day or nifedipine CR 40 mg/day)/HCTZ (12.

Advanced glycation of high-density lipoprotein and the functionality of aldosterone release in type 2 diabetes.

Patients with type 2 diabetes mellitus (DM) exhibit modification of high-density lipoprotein (HDL), which is likely to have an important role in the development of atherosclerotic cardiovascular disease (ASCVD). Excess production of aldosterone (Ald) results in hypertension as well as ASCVD. However, the biological activity of modified HDL in steroidogenesis is not clear.

Associations between parameters of flow-mediated vasodilatation obtained by continuous measurement approaches and the presence of coronary artery disease and the severity of coronary atherosclerosis.

We investigated the associations between the parameters of flow-mediated vasodilatation (FMD) obtained by continuous measurement approaches and the presence of coronary artery disease (CAD) and the severity of coronary atherosclerosis. The subjects consisted of 282 consecutive patients who underwent coronary angiography (CAG) and in whom we could measure FMD. Using continuous measurement approaches, we measured FMD as the magnitude of the percentage change from brachial artery diameter from baseline to peak (bFMD), the maximum FMD rate calculated as the maximal slope of dilation (FMD-MDR), and the integrated FMD response calculated as the area under the dilation curve during the 60- and 120 s dilation periods (FMD-AUC60 and FMD-AUC120).

Evaluation of the antithrombotic abilities of non-vitamin K antagonist oral anticoagulants using the Total Thrombus-formation Analysis System.

The Total Thrombus-formation Analysis System (T-TAS) is a novel automated microchip flow-chamber system for the quantitative evaluation of thrombus formation under blood flow conditions. T-TAS uses two types of microchip to evaluate thrombus formation: the AR-chip quantifies white thrombus formation and the PL-chip quantifies platelet thrombus formation. We assessed the antithrombotic abilities of various non-vitamin K antagonist oral anticoagulants (NOACs) using T-TAS.

Significance of the percentage of cholesterol efflux capacity and total cholesterol efflux capacity in patients with or without coronary artery disease.

We hypothesized that cholesterol efflux capacity is more useful than the lipid profile as a marker of the presence and the severity of coronary artery disease (CAD). Therefore, we investigated the associations between the presence and the severity of CAD and both the percentage of cholesterol efflux capacity and total cholesterol efflux capacity and the lipid profile including the high-density lipoprotein cholesterol (HDL-C) level in patients who underwent coronary computed tomography angiography (CTA). The subjects consisted of 204 patients who were clinically suspected to have CAD and underwent CTA.

Impact of the Absolute Difference in Diastolic Blood Pressure Between Arms in Patients With Coronary Artery Disease.

Background: We investigated the relationship between the severity and presence of coronary artery disease (CAD) and a difference in systolic and diastolic blood pressure (SBP and DBP) between arms or between lower limbs.

Methods: We enrolled 277 patients who underwent coronary angiography. We calculated the absolute (|right BP (rt.

Association between pentraxin 3 levels and aortic valve calcification.

Objective: Aortic valve calcification (AVC) reflects the state of aortic valve sclerosis (AVS), which is a precursor to aortic valve stenosis (AS). Therefore, we investigated the presence of AVC in patients who underwent coronary computed tomography angiography (CTA), which is an effective tool for evaluating early-stage AVC, and examined the association between plasma levels of pentraxin 3 (PTX3) and AVC.

Methods And Results: The subjects consisted of 162 consecutive patients who underwent CTA and in whom we could measure plasma levels of PTX3.

Association between the severity of coronary artery stenosis and the combination of the difference in blood pressure between arms and brachial-ankle pulse wave velocity.

Background: A difference in systolic blood pressure (SBP) ≥10 mmHg between the arms is associated with an increased risk of coronary artery disease (CAD) and mortality in high-risk patients.

Methods And Results: Four hundred and fourteen patients were divided into three groups according to the percent most severe luminal narrowing of a coronary artery as diagnosed by coronary computed tomography angiography: no or mild coronary stenosis (0-49%), moderate stenosis (50-69%) and severe stenosis (≥70%) groups. The relative difference in SBP between arms in the severe group was significantly lower than those in the no or mild and moderate groups.

Efficacy and safety of combination therapy of high-dose losartan and hydrochlorothiazide in patients with hypertension.

Objective: We analyzed the efficacy and safety of combination therapy of high-dose losartan (100 mg/day) and hydrochlorothiazide (HCTZ, 12.5 mg/day) compared with those of the combination of high-dose telmisartan (80 mg/day) and HCTZ (12.5 mg/day).

Associations between glycated albumin or hemoglobin A1c and the presence of coronary artery disease.

Objective: We investigated the associations between serum levels of glycated albumin (GA) or hemoglobin A1c (HbA1c) and the presence of coronary artery disease (CAD) in patients who underwent coronary computed tomography angiography (CTA).

Methods And Results: The study consisted of 244 consecutive patients who underwent CTA and in whom we could measure the levels of both GA and HbA1c. Any narrowing of the normal contrast-enhanced lumen to >50% that could be identified in multiplanar reconstructions or cross-sectional images by CTA was defined as significant stenosis in CAD.

Is pentraxin 3 a biomarker, a player, or both in the context of coronary atherosclerosis and metabolic factors?

The objective of this study is to determine whether pentraxin-3 (PTX-3) is clinically a biomarker of inflammation, a player in anti-inflammation, or both with regard to coronary atherosclerosis, we compared levels of PTX-3 with levels of adiponectin in addition to high-sensitivity C-reactive protein (hs-CRP). We enrolled 693 patients (51 % male; mean age 64 ± 12 years) at Fukuoka University Hospital. They were clinically suspected to have coronary artery disease (CAD) or had at least one cardiac risk factor and had undergone coronary computed tomography angiography (CTA).

The ratio of low-frequency to high-frequency in ambulatory electrocardiographic monitoring immediately before coronary angiography as a predictor of the presence of coronary artery disease.

Background: There is considerable evidence that impaired autonomic control may be associated with the etiology of coronary artery disease (CAD). We hypothesized that the autonomic imbalance as assessed by measuring heart rate variability (HRV) and biological parameters before and after coronary angiography (CAG) may predict the presence of CAD.

Methods: Ambulatory electrocardiographic (ECG) examination using eHEART(®) (Parama-Tec) is a novel, rapid, and simple method with which we can measure HRV within 5 min.

Contrast between innovator drug- and generic drug-induced renal dysfunction on coronary angiography (CONTRAST study).

Contrast-induced nephropathy (CIN) has gained increasing attention in clinical practice, particularly during coronary angiography (CAG). However, some "bioequivalent" generic (GE) drugs are less effective than the innovator (IN) drug. Therefore, the aim of this study was to compare contrast media (IN drug)-induced renal dysfunction with contrast media (GE drug)-induced dysfunction.

Efficacy and safety of a single-pill fixed-dose combination of high-dose telmisartan/hydrochlorothiazide in patients with uncontrolled hypertension.

Objective: Many patients still have high blood pressure (BP) after treatment with high-dose angiotensin II type 1 receptor blockers (ARBs) or Preminent® (medium-dose of losartan (50 mg/day)/hydrochlorothiazide (HCTZ) (12.5 mg/day)). Therefore, we analyzed whether Micombi®BP (high-dose telmisartan (80 mg/day)/HCTZ (12.
