To investigate whether apelin can be used as an indicator to predict postoperative atrial fibrillation in patients with coronary atherosclerotic heart disease, and to provide an objective basis for the clinical selection of a preventive intervention program for atrial fibrillation.
No successful strategy is proposed to patients submitted to important surgery to reduce the incidence of postoperative cognitive disorders (POCD) onset. In our project, we propose to measure plasma levels of apelin in wide population submitted to orthopedic surgery. Apelin could be involved in anti-inflammatory processes. Apelin levels before and after surgery correlated to postoperative cognitive disorders symptom measured by PET-Scan could be an important predictive or diagno...
The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease. Two of the main actions of apelin are to increase the pumping ability of the heart and cause blood vessels to relax. The investigators wish to assess if these actions are altered in the setting of normal renin-angiotensin activation and increased renin-angio...
Comparison of Effectiveness of Ranolazine Plus Metoprolol Combination vs. FlecainidE pluS Metoprolol Combination in ATrial Fibrillation Recurrences FOllowing PhaRmacological or Electrical CardioverSion of AtRial Fibrillation
Atrial fibrillation (AF) is the most common arrhythmia in clinical practice with a prevalence reaching 5% in patients older than 65 years and an incidence that increases progressively with age.1 According to the most recent guidelines, class Ic anti-arrhythmic drugs are considered the first line treatment in patients without significant structural heart disease. Flecainide is effective in preventing AF recurrences in 31-61% of cases according to different studies.2-5 A recent s...
Postoperative new-onset atrial fibrillation (AF) is the most common complication stemming from coronary artery bypass graft surgery, and is associated with increased early and late mortality risk. Standard guidelines recommend β blockers for the prevention of AF; however, no prospective study has compared the relative efficacy of β-blocking agents. We hypothesize that carvedilol, a non-selective adrenergic blocker with both anti-inflammatory and antioxidant properties, is m...
This is a sigle-center, prospective study to evaluate the role of D-Dimer testing in patients with atrial fibrillation receiving Dabigatran or warfarin anticoagulation therapy.
Preclinical studies have demonstrated in mouse models that (PYR1)-apelin-13 exerts a glucose-regulating action in vivo. The (PYR1)-apelin-13 effect on insulin sensitivity in healthy overweighed volunteers has been previously assessed in a phase I clinical trial (APELINS study; NCT02033473). The APELINS-2 clinical trial aims to expand the initial proof of concept to the population targeted by future innovative insulin-sensitizing therapies: patients living with type 2 diabetes.
The purpose of this study is to determine if preforming a posterior left pericardiotomy prevents atrial fibrillation after cardiac surgery.
The objective of this registry is the characterization of patients with atrial fibrillation (AF) with confirmed valvular heart disease (VHD) who are prescribed edoxaban in a real-life clinical setting.
The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease. Apelin has the ability to cause blood vessels to relax, increasing their diameter and hence blood flow down the blood vessel. The researchers wish to investigate the hypothesis that an infusion of apelin will reduce the effects of angiotensin II, which is kn...
The apelin-APJ system is a relatively new discovery. It has generated interest in part due to it's apparent ability to counteract the renin-angiotensin system, which is frequently overactive in many cardiovascular disease. Apelin improves that pumping ability of the heart and we wish to know if this action persists in the presence of increased levels of angiotensin II.
Atrial fibrillation is the most common cardiac arrhythmia and is expected to affect about 30 million North Americans and Europeans by 2050. Atrial fibrillation is associated with increased cardiovascular morbidity and mortality, with stroke being an especially important and potentially devastating complication. Many studies have investigated the efficacy of different drugs in converting atrial fibrillation to sinus rhythm. There are numerous randomized controlled trials that ha...
The DExamethasone for Cardiac Surgery - Postoperative New-onset Atrial Fibrillation (DECS-PNAF) project described in this protocol aims to elucidate how corticosteroids protect cardiac surgical patients from Postoperative New-onset Atrial Fibrillation (PNAF). Patients will be randomized to receive either a single high dose of dexamethasone or a placebo. Continuous ECG-monitoring, echocardiography and biochemical and genomic analyses will be used to investigate the mechanisms re...
The laboratory test, C-Reactive Protein (CRP), has become well established as a marker of inflammation. Recently a high CRP level (indicating an increase in inflammation) was identified as a risk factor for atrial fibrillation. We are conducting this study with patients such as yourself with atrial fibrillation who are planning to undergo cardioversion to determine what sort of relationship exists between CRP levels and atrial fibrillation. We will then look at success rates ...
Type two diabetes mellitus (T2DM) is a common, long term metabolic disorder characterised by hyperglycaemia (high blood glucose) resulting from insulin resistance and relative insulin insufficiency. The risk of developing insulin resistance and subsequently T2DM is increased by being overweight and also through a sedentary lifestyle. As the onset can be gradual, physiological damage may have occurred prior to diagnosis. Diabetes is associated with the development of microvascul...
Many people who suffer from irregular heartbeats (atrial fibrillation) which might cause stroke, need to take blood thinners to prevent it. However, people with atrial fibrillation are also at increased risk of acute myocardial infarction or unstable angina pectoris (another heart condition marked by a chest pain, comprising so-called acute coronary syndrome for which another type of treatment that prevents blood from clotting (antiplatelet treatment) is indicated. In particula...

The optimal antithrombotic treatment for Coronary Heart disease (CHD) patients combined with Atrial Fibrillation (AF) is the hotspot at present. Although the European and American guidelines have given a hand for us, however,there is absence of solid evidence-based data on the safety of antithrombotic therapy in Asian populations. A vailable clinical trials and registries provide remarkably little evidence to guide difficult clinical decision making in patients with combined AF...
In patients undergoing elective coronary artery bypass grafting (CABG) surgery, coronary artery disease, sleep-disordered breathing (SDB), atrial fibrillation (AF) perioperative atrial fibrillation and complications will be assessed. The primary objective is to determine, whether SDB patients have a higher rate of Major Adverse Cardiac and Cerebrovascular Events (MACCE) within 30 days after surgery compared to those without SDB.
Sudden death is a natural death occurring within one hour after the onset of symptoms. It remains a major public health problem and accounts for 5 to 10 % of the annual total mortality ie about 300.000 in the United States. Despite community-based interventions, overall survival remains below 5%. Better understanding of the mechanisms causing sudden death could allow early identification of high risk subjects and implementation of specific prevention strategies. The cause of mo...
The benefit of a drug-eluting stent (DES) in patients with acute myocardial infarction (AMI) is controversial. This study will aim to observe the effect of a DES on the risk of new-onset AF in patients with AMI.
