The development of coronary revascularization has dramatically improved early cardiovascular outcomes in patients with acute coronary syndrome (ACS). However, patients who have experienced myocardial infarction (MI) are at high risk of recurrence of cardiovascular events compared with those who are healthy or have stable coronary artery disease. Acute coronary events induce further inflammatory responses and plaque vulnerability in either a coronary culprit or whole vessels. The majority of data have supported the importance of coronary risk management to prevent secondary events...

Patients with cardiovascular disease (CVD) often have multiple comorbid conditions that may interact with each other, confound the choice of treatments, and reduce mortality. Chronic obstructive pulmonary disease (COPD) is one of the most important comorbidities of CVD, which causes serious consequences in patients with ischemic heart disease, stroke, arrhythmia, and heart failure. COPD shares common risk factors such as tobacco smoking and aging with CVD, is associated with less physical activity, and produces systemic inflammation and oxidative stress...

BACKGROUND: Kawasaki disease (KD) is a pediatric vasculitis of unknown origin. Its main complication is the development of coronary artery aneurysms (CAA) with giant CAA at the end of the spectrum. METHODS: In this cohort study, we evaluated the association between patient characteristics and the development of giant CAA based on z-scores. Multivariable, multinomial logistic regression analysis was used to identify variables associated with giant CAA. RESULTS: A total of 301 KD patients, comprising 216 patients without enlargement, 45 with small-sized, 19 with medium-sized, and 21 with giant CAA with all echocardiographies at our center were retrospectively included...

Obesity leads to the development of cardiovascular diseases. Adipose tissue produces various bioactive molecules, also known as adipokines, and imbalanced production of adipokines contributes to the pathogenesis of obesity-linked metabolic and cardiovascular complications. Some adipokines such as adiponectin exert salutary actions on cardiovascular and metabolic disorders. Recent research has been conducted to identify poorly-characterized adipokines involved in cardiovascular regulation. In this review, we focus on the protective role of novel adipokines that are of current interest in the field of cardiology...

REVIEW

Chronic total occlusion (CTO) is a challenging subset of coronary artery disease that is commonly encountered in real-world practice; it is associated with worse long-term prognosis. Observational studies suggest that percutaneous coronary intervention (PCI) for CTO is associated with reduction in myocardial ischemia and improvement in quality of life and left ventricular function. Some observational studies suggested that CTO-PCI is associated with improvement of the 'hard' clinical endpoints; others did not...

BACKGROUND: Catecholamine sensitivity estimated using a dobutamine stress test (DST) is recognized as a measure of the beta-adrenergic myocardial contractile reserve, which is involved with left ventricular reverse remodeling (LV-RR). We investigated whether the prognostic ability of the DST for LV-RR could predict cardiac events. METHODS: There was a total of 192 enrolled patients with dilated cardiomyopathy (DCM). DCM was defined as a LV ejection fraction (LV-EF) ≤45% and LV end-diastolic dimension (LVDd) ≥55mm...

BACKGROUND: Doppler echocardiography is ideally suited for assessment of diastolic function, being widely available, non-invasive, and less expensive than other techniques. However, data regarding age- and gender-matched reference values of right ventricular diastolic function are limited. This study aims to explore the physiologic variations of right ventricle (RV) diastolic function in a large cohort of healthy adults, and to investigate clinical and echocardiographic correlates. METHODS: From June 2007 to February 2014, 1168 healthy Caucasian subjects [mean age 45...

Myocardial perfusion imaging using positron emission tomography (PET) allows both qualitative and quantitative measurement. The quantitative myocardial blood flow and coronary flow reserve (CFR) are reliable indices for evaluating functional severity, influenced by both epicardial stenosis and microvascular disease. Fractional flow reserve (FFR) also reflects physiological stenosis, which measures the pressure differences across a coronary artery stenosis during maximum hyperemia. Discordance between CFR and FFR has been noticed in estimating the functional significance of coronary stenosis...

BACKGROUND: Metabolic profiles have been shown to provide prognostic information in patients with heart failure (HF). Galectin-3 (Gal-3), indicating cardiac fibrosis, is a documented biomarker of prognosis in HF. It is unknown whether metabolic profiles provide prognostic value better than Gal-3. METHODS AND RESULTS: This study analyzed 212 hospitalized HF patients, measuring metabolic score (composed by butyrylcarnitine, dimethylarginine/arginine ratio, spermidine, and total essential amino acids) and Gal-3...

BACKGROUND: Myocardial ischemia induces cardiac dysfunction, resulting in insufficient oxygen supply to peripheral tissues and mismatched energy production during exercise. To relieve the insufficient oxygen supply, heart rate (HR) response is augmented; however, beta-adrenergic receptor blockers (BB) restrict HR response. Although BB are essential drugs for angina pectoris, the effect of BB on exercise tolerance in patients with angina has not been studied. The aim of this study was to clarify the importance of HR augmentation to preserve exercise tolerance in patients with angina pectoris...

BACKGROUND: Limited fluoroscopy ablation using 3D electro-anatomical system (3DS) has been used for arrhythmias in children, however it is not a common practice. We aimed to facilitate a fluoroscopy limited approach for ablation of accessory pathways (AP) in children. METHODS: Following electrophysiologic (EP) catheter placement a single dual-plane fluoroscopic image (right anterior oblique-30° and left anterior oblique-60° views) was acquired and the 3DS views were rotated to be a perfect match to the fluoroscopy...
