Some patients with unstable angina and critical stenosis of the left anterior descending coronary artery (LAD) present with Wellens syndrome (WS), i.e., inverted or biphasic T-waves in the anterior precordial leads. We assessed clinical, angiographic, electro- and echocardiographic characteristic of patients with WS. In this retrospective study, clinical, angiographic, electro- and echocardiographic characteristic of 35 patients with WS were compared to 57 patients with critical LAD stenosis and normal resting electrocardiogram (ECG), and 45 subjects with normal coronary angiogram...

Adipose triglyceride lipase (ATGL) is a rate-limiting enzyme that mobilizes fatty acids from cellular triglyceride stores. Metabolic syndrome, which refers to a group of abnormalities that occur together and increase the risk of coronary artery disease, stroke, type-2 diabetes, and cachexia, can be treated using ATGL-specific inhibitors. Atglistatin (1) is the first small-molecule inhibitor of ATGL. In this study, we designed and synthesized 29 Atglistatin derivatives and evaluated their inhibition of forskolin-stimulated lipolysis in 3T3-L1 adipocytes as an indicator of their potential to inhibit ATGL in adipose tissues...

BACKGROUND: Contrast-induced acute kidney injury (CI-AKI) is one of the most serious complications in patients who undergo percutaneous coronary intervention (PCI), especially in those with acute coronary syndrome. It has been shown that inflammation may play an important role in the pathophysiology of CI-AKI. HYPOTHESIS: Inflammatory factors may play a predominant role in the prediction of CI-AKI in patients who undergo emergency PCI. METHODS: Patients who underwent emergency PCI from 2013 to 2015 were consecutively enrolled and were divided into CI-AKI and non-CI-AKI groups...

In the Guidance for Industry from the Food and Drug Administration in 2008, excess cardiovascular risk should be ruled out in trials of all new antidiabetic drugs; however, relatively few studies have focused on cardiovascular safety with antidiabetic drug use. We aimed to examine mortality and cardiovascular risk using a network meta-analysis. We searched the Medline, Embase, Cochrane, and ClinicalTrials.gov registry databases in March 2016 to identify randomized controlled trials reporting cardiovascular risk with the following oral antidiabetic drugs: metformin, sulfonylureas, thiazolidinedione (TZD), dipeptidyl peptidase-4 (DPP4) inhibitors, and sodium-glucose co-transporter-2 (SGLT2) inhibitors...

BACKGROUND: Women with signs and symptoms of ischemia, no obstructive coronary artery disease (CAD) and preserved left ventricular ejection fraction (EF) often have diastolic dysfunction and experience elevated rates of major adverse cardiac events (MACE), including heart failure (HF) hospitalization with preserved ejection fraction (HFpEF). We evaluated the predictive value of inflammatory biomarkers for long-term HF hospitalization and all-cause mortality in these women. METHODS: We performed a cross-sectional analysis to investigate the relationships between inflammatory biomarkers [serum interleukin-6 (IL-6), C-reactive protein (hs-CRP) and serum amyloid A (SAA)] and median of 6 years follow-up for all-cause mortality and HF hospitalization among women with signs and symptoms of ischemia, non-obstructive CAD and preserved EF...

Infective endocarditis (IE) is uncommon, however, the incidence is on the rise [1]. Despite improvements in its management, infective endocarditis (IE) is associated with significant short- and long-term morbidity and mortality [2]. A definitive diagnosis of IE may be challenging and is often delayed due to the highly variable and non-specific symptoms at patient presentation, alongside limited availability of specialist services [3]. In addition to IE remaining a diagnostic challenge, the decisions about the treatment modality (medical vs surgical) and the timing of potential valve surgery are demanding, despite established national and international guidelines [4]...

In the recent decades, systemic inflammation, as a clinical phenomenon, has been the focus of extensive research particularly with regard to its potential association with a variety of cardiovascular diseases including atherogenesis and acute coronary syndromes. Within this context, there also exists a potential link between systemic inflammation and cardiac arrhythmogenesis in various aspects. Accordingly, systemic inflammation response as measured with inflammation markers (cytokines, etc) has been investigated in the setting of well-known cardiac arrhythmias including atrial fibrillation and ventricular tachycardia...
