Right atrial strain measured by 2D speckle-tracking echocardiography is associated with poor cardiac outcomes in patients with heart failure.

Right heart failure (HF) is a poor prognostic factor in patients with HF. The right atrial (RA) function has attracted less attention than the right ventricular (RV) function. The association of RA reservoir strain evaluated by 2D speckle-tracking echocardiography (2DSTE) with clinical outcomes in patients with HF remains unclear.

Usefulness of Inter-Hospital Heart Team Conference Based Collaborative Outpatient Cardiac Rehabilitation in Patients with Cardiovascular Disease.

An inter-hospital heart team conference based collaborative follow-up (FU) may facilitate outpatient cardiac rehabilitation (CR) programs, especially in hospitals without an outpatient CR center. Consecutive 145 patients with cardiovascular disease who received inpatient treatment at Yamagata University Hospital were divided into collaborative (n = 76) and same-hospital (n = 69) FU groups. In the collaborative FU group, patients received outpatient care at a university hospital and outpatient CR at different hospitals.

Perfusion Balloon Is Useful for Preventing Obstruction of Left Main Coronary Artery During Transcatheter Aortic Valve Implantation.

The incidence of acute coronary obstruction during transcatheter aortic valve implantation (TAVI) is low (< 1.0%); however, it is associated with high mortality. An 83-year-old female with a history of chest pain and syncope was diagnosed with severe aortic stenosis.

Growth Factor Midkine Aggravates Pulmonary Arterial Hypertension via Surface Nucleolin.

Pulmonary arterial hypertension (PAH) is a progressive fatal disease caused by pulmonary arterial remodeling. Midkine regulates cell proliferation and migration, and it is induced by hypoxia, but its roles in pulmonary arterial remodeling remain unclear. Serum midkine levels were significantly increased in PAH patients compared with control patients.

The association between microRNA-21 and hypertension-induced cardiac remodeling.

Hypertension is a major public health problem among the aging population worldwide. It causes cardiac remodeling, including hypertrophy and interstitial fibrosis, which leads to development of hypertensive heart disease (HHD). Although microRNA-21 (miR-21) is associated with fibrogenesis in multiple organs, its contribution to cardiac remodeling in hypertension is poorly understood.

Therapeutic inhibition of microRNA-34a ameliorates aortic valve calcification via modulation of Notch1-Runx2 signalling.

Aims: Calcific aortic valve stenosis (CAVS) is the most common valvular heart disease and is increased with elderly population. However, effective drug therapy has not been established yet. This study aimed to investigate the role of microRNAs (miRs) in the development of CAVS.

Cardiac Nuclear High-Mobility Group Box 1 Ameliorates Pathological Cardiac Hypertrophy by Inhibiting DNA Damage Response.

High-mobility group box 1 (HMGB1) is a deoxyribonucleic acid (DNA)-binding protein associated with DNA repair. Decreased nuclear HMGB1 expression and increased DNA damage response (DDR) were observed in human failing hearts. DNA damage and DDR as well as cardiac remodeling were suppressed in cardiac-specific HMGB1 overexpression transgenic mice after angiotensin II stimulation as compared with wild-type mice.

Impact of Iron Deficiency on Peripheral Artery Disease After Endovascular Therapy.

Despite advances in endovascular therapy (EVT), peripheral artery disease (PAD) is a public health problem associated with high cardiovascular mortality. Iron deficiency (ID) is associated with poor clinical outcome in patients with heart disease, but whether ID is associated with the severity and clinical outcome of PAD remains unclear. A total of 449 patients with PAD who received EVT and who had iron and red blood cell measurement were enrolled.

Decreased Psoas Muscle Computed Tomography Value Predicts Poor Outcome in Peripheral Artery Disease.

Background: The prognosis of peripheral artery disease (PAD) and comorbid sarcopenia is poor. Some reports indicate that the computed tomography (CT) value of skeletal muscle, which reflects intramuscular fat deposition as well as skeletal muscle mass, is considered a marker of sarcopenia. However, it remains unclear if skeletal muscle area and CT value are associated with poor outcomes in patients with PAD.

Ventricular wall stress and silent myocardial damage are associated with pulse pressure in the general population.

Pulse pressure (PP) is a risk factor for cardiovascular diseases and is associated with increased afterload and myocardial oxygen demand. Brain natriuretic peptide (BNP) and heart-type fatty acid-binding protein (H-FABP) are known as biomarkers indicating ventricular wall stress and silent myocardial damage. However, the association between PP and ventricular wall stress and silent myocardial damage in the general population is unclear.

Increased plasma xanthine oxidoreductase activity deteriorates coronary artery spasm.

Increased reactive oxygen species (ROS) contributes to the development of endothelial dysfunction, which is involved in coronary artery spasm (CAS). Xanthine oxidoreductase (XOR) plays a pivotal role in producing both uric acid and ROS. However, the association between plasma XOR activity and CAS has not been elucidated.

Circulating Surfactant Protein-D Is Associated With Clinical Outcomes in Peripheral Artery Disease Patients Following Endovascular Therapy.

Background: Peripheral artery disease (PAD) is a risk factor for the development of cardiovascular disease and death. Surfactant protein-D (SP-D) is a 43-kDa protein secreted from type II pneumocytes in the lungs. Recent studies have demonstrated that circulating SP-D plays a key role in the development of atherosclerosis and is related to clinical outcomes in patients with ischemic heart disease.

The impact of non-alcoholic fatty liver disease fibrosis score on cardiac prognosis in patients with chronic heart failure.

Liver abnormalities have a strong impact on clinical outcomes in patients with heart failure (HF), and are known as cardio-hepatic syndrome. The non-alcoholic fatty liver disease (NAFLD) fibrosis score (NFS) has been developed to identify liver fibrosis in patients with NAFLD. It remains to be determined whether NFS is associated with cardiovascular prognosis in patients with chronic heart failure (CHF).

Impact of Objective Malnutrition Status on the Clinical Outcomes in Patients With Peripheral Artery Disease Following Endovascular Therapy.

Background: Peripheral artery disease (PAD) is an athero-occlusive disease and a known risk factor for cardiovascular events. The controlling nutritional status (CONUT) score and geriatric nutritional risk index (GNRI) are objective tools for evaluating malnutrition and are reportedly associated with poor clinical outcomes in patients with fatal diseases. However, the effect of malnutrition on the clinical outcomes in patients with PAD remains unclear.

Association of plasma xanthine oxidoreductase activity with severity and clinical outcome in patients with chronic heart failure.

Background: Oxidative stress due to purine degradation is associated with the development of chronic heart failure (CHF). Xanthine oxidoreductase (XOR) is a rate-limiting enzyme of purine degradation that plays a key role in uric acid (UA) production with a resultant increase in reactive oxygen species. However, the relationship between plasma XOR activity and CHF severity and clinical outcome remains unclear.

Deficiency of Senescence Marker Protein 30 Exacerbates Cardiac Injury after Ischemia/Reperfusion.

Early myocardial reperfusion is an effective therapy but ischemia/reperfusion (I/R) causes lethal myocardial injury. The aging heart was reported to show greater cardiac damage after I/R injury than that observed in young hearts. Senescence marker protein 30 (SMP30), whose expression decreases with age, plays a role in reducing oxidative stress and apoptosis.
