BACKGROUND: Although statin use has been indicated to prevent atrial fibrillation in previous observational and experimental trials, the issue remains inadequately and insufficiently explored. We therefore performed this meta-analysis to evaluate the effects of perioperative statin therapy on complications and short-term prognosis following cardiac surgery. METHODS: A search of the PubMed, EMBASE and the Cochrane database of controlled trials was performed from inception to June 2016 to identify relevant randomized controlled trials (RCTs)...

BACKGROUND: Diabetic cardiomyopathy is a major risk factor in diabetic patients but its pathogenesis remains poorly understood. The ubiquitin-proteasome system (UPS) facilitates protein quality control by degrading unnecessary and damaged proteins in eukaryotic cells, and dysfunction of UPS is implicated in various cardiac diseases. However, the overall functional status of the UPS and its pathophysiological role in diabetic cardiomyopathy have not been determined. METHODS AND RESULTS: Type I diabetes was induced in wild-type and transgenic mice expressing a UPS functional reporter (GFPdgn) by injections of streptozotocin (STZ)...

In this study we wanted to verify the diagnostic value of tilt table test (TTT) to predict the efficacy of cardiac pacing (PM) for preventing recurrences of neurally mediated reflex syncope (NMS) in patients with cardioinhibitory activity (CI) documented by implantable loop recorder (ILR). Among patients selected by ILR in the context of severe clinical presentation of NMS, we analysed those who underwent PM implantation. In this observational and retrospective study we wanted to verify the results of TTT in the groups of treated patients with and without recurrences...

OBJECTIVE: Endoluminal aortic aneurysm repair is suitable within certain anatomic specifications. This study aims to compare 30-day outcomes of endovascular versus open repairs for juxtarenal and pararenal aortic aneurysms (JAA/PAAs). METHODS: The ACS-NSQIP database was queried from 2012 to 2015 for JAA/PAA repairs. Procedures characterized as emergent were included in the study; however, failed prior repairs and ruptured aneurysms were excluded. The preoperative and perioperative patient characteristics, operative techniques, and outcome variables were compared between the open aortic repair and the endovascular aortic repair groups...

Patients with kidney disease have a significantly increased cardiovascular morbidity and mortality. Especially diabetics have an increased risk to develop renal insufficiency and cardiovascular events. Two recent studies show that the SGLT2 inhibitor Empagliflozin and the GLP1 agonist Liraglutid are able to lower the cardiovascular risk of type2 diabetics with renal insufficiency. Recent observations suggest that bradycardia and asystole are main triggers for sudden cardiac death in patients with chronic kidney disease...

Patients with pulmonary arterial hypertension (PAH) who do not have an adequate response to therapy with phosphodiesterase-5 inhibitors (PDE-5i) may have insufficient synthesis of cyclic guanosine monophosphate (cGMP). These patients may respond to a direct soluble guanylate cyclase (sGC) stimulator such as riociguat. RESPITE (NCT02007629) was an open-label, multicenter, uncontrolled, single-arm phase 3b study of riociguat in patients with PAH who demonstrated an insufficient response to treatment with PDE-5i...

REVIEW
Samir Nusair
The incremental cardiopulmonary exercise test (CPET) is an increasingly used diagnostic method that serves to evaluate patients with chief complaint of dyspnea during exercise. Performing maximal symptom-limited CPET can show if the tested subject has a reduced exercise capacity and give clues to the mechanism of such exercise capacity reduction, cardiac, pulmonary, or pulmonary vascular source. In this review, it is suggested that the evaluation of the complex results of CPET should be performed by first determining if myocardial/circulatory insufficiency is present and second if there is gas exchange abnormality...

Sudden cardiac death (SCD) is a major public health issue due to its increasing incidence in the general population and the difficulty in identifying high-risk individuals. Nearly 300 000 - 350 000 patients in the United States and 4-5 million patients in the world die annually from SCD. Coronary artery disease and advanced heart failure are the main etiology for SCD. Ischemia of any cause precipitates lethal arrhythmias, and ventricular tachycardia and ventricular fibrillation are the most common lethal arrhythmias precipitating SCD...

BACKGROUND: Patients supported with extracorporeal membrane oxygenation (ECMO) are given priority listing status for heart transplant (HT). Data on post-HT outcomes for adults with ECMO support at the time of HT are limited. METHODS: We analyzed data from the United Network for Organ Registry (UNOS) registry for 157 ECMO-supported adults (age ≥ 18 years) undergoing HT after January 1, 2000. Data at the time of HT were examined for their association with post-transplant mortality using multivariable Cox proportional hazard analyses...

BACKGROUND: Cardiac myxomas (CMs) are a major primary heart tumor which often causes unexpected symptoms or sudden death. Among CMs, biatrial myxomas are even rare. This study was designed to investigate the clinical characteristics and surgical treatment of 5 cases with biatrial myxoma, to summarize the treatment experience and the effect of short-to-mid-term prognosis. METHODS: Five patients with biatrial myxoma were included in this study. The patients' relative literature, chest X-ray, body-surface electrocardiogram, and ultrasonic cardiogram (UCG) were used to investigate the clinical characteristics...

BACKGROUND: Ultrafiltration is a method used to achieve diuresis in acute decompensated heart failure (ADHF) when there is diuretic resistance, but its efficacy in other settings is unclear. We therefore conducted a systematic review and meta-analysis to evaluate the use of ultrafiltration in ADHF. METHODS: We searched MEDLINE and EMBASE for studies that evaluated outcomes following filtration compared to diuretic therapy in ADHF. The outcomes of interest were body weight change, change in renal function, length of stay, frequency of rehospitalization, mortality and dependence on dialysis...

OBJECTIVE: Fetal growth restriction is a powerful determinant of poor perinatal outcomes. Our previous work in pregnancies at high risk for the development of hypertension found that early in pregnancy maternal haemodynamics show impaired cardiovascular adaptation in gestations destined to deliver growth-restricted infants. In this study, we serially monitored maternal haemodynamics from the first through to the third trimester in a similar high-risk cohort, in order to determine if, in pregnancies complicated by growth-restriction, these distinct haemodynamic profiles found at presentation persisted throughout pregnancy...

Background: Cardiovascular Disease (CVD) is the leading burden of disease worldwide. Moreover, CVD-related death rates are considered an epidemic in low- and middle-income countries (LMICs). Research shows that cardiac rehabilitation (CR) participation reduces death and improves disability and quality of life. Given the growing epidemic of CVD in LMICs and the insufficient evidence about CR programs in these countries, a Randomized Control Trial (RCT) in Latin America is warranted. Objective: To investigate the effects of comprehensive CR on functional capacity and cardiovascular risk factors...

Brent T Boettcher, Timothy J Olund, Paul S Pagel
INTRODUCTION: Eptifibatide is a platelet glycoprotein IIb/IIIa (GP IIb/IIIa) receptor antagonist that inhibits fibrinogen binding to the activated GP IIb/IIIa site and prevents platelet-platelet interaction and clot formation. GP IIb/IIIa inhibitors improve outcome in patients undergoing percutaneous coronary intervention for acute coronary syndrome. Thrombocytopenia is a complication of GP IIb/IIIa inhibitors, but severe thrombocytopenia is unusual. Most reported cases of severe thrombocytopenia after eptifibatide occurred in patients with acute coronary syndrome...

Impedance cardiography measurement of cardiac output gained wide interest due to its ease of use and non-invasiveness. However, validation studies of different algorithms yielded diverging results. Bioreactance (BR) as a recent adaption differs fundamentally as the flow signal is derived from phase shifts. Our aim was to assess the accuracy and reproducibility of BR, as compared to the non-invasive gold standard--cardiac magnetic resonance imaging (CMR). We prospectively included 32 stable patients. BR was performed twice in the supine position and averaged over 30 seconds...
