Active clinical trials for "Syncope"

Objective: To determine if atomoxetine 40 mg bid (bis in die) in patients ≥18 years old with recurrent vasovagal syncope will better prevent syncope during tilt testing than placebo.

Syncope affects about 50% of Canadians, is the cause of 1 - 2% of all emergency room visits, and probably is responsible for CDN $250 million in health care spending each year. It is associated with decreased quality of life, trauma, loss of employment, and limitations in daily activities. It is a particular problem for older people, partly because of increased frailty, and partly because of a difficult differential diagnosis. One of the causes in older adults is intermittent complete heart block in the setting of bifascicular heart block, but they may also faint due to a variety of tachyarrhythmias, sick sinus syndrome, and several neurally mediated syncopes. Often treatment decisions should be made before the true cause is apparent.

This randomized controlled trial will examine the impact of local anesthetic on the frequency of vasovagal reactions and the patients perception of pain during femoral arterial sheath removal after percutaneous coronary intervention.

Syncope is a common problem that many clinicians may encounter in various outpatient settings. Neurocardiogenic syncope (NCS) is a benign condition characterized by a self limited episode of systemic hypotension. Patients are usually managed with education on syncope, anxiety management, and coping skills. It has been established that practice of Yoga could relieve stress and anxiety. In a different study, they also found that Yoga positively influences cardiovascular function by decreasing the heart rate and blood pressure. The main objective of Yoga is to achieve control over the autonomic nervous system and able to control functions like heart rate, blood pressure and respiratory rate. Based on the findings that Yoga relieves stress and reduces heart rate, the investigators propose to study if Yoga can decrease the frequency of NCS and also reduce the symptoms associated with these episodes.

The current proposal will determine if blocking carbohydrate intake in the small intestine with Acarbose can be a possible therapy for older adults with (PPH) Post Prandial Hypotension (a drop of blood pressure after eating), which can result in falls.

Beneficial effect of chronic hydration with salt supplementation in patients with recurrent unexplained syncope is not established. We sought to determine if chronic oral rehydration with salt supplementation improved the tolerance and hemodynamic responses of patients with unexplained recurrent syncope.

The main purpose of this study is to assess the reliability of a new patient's self-administered wearable watch-type BP monitor in detecting episodes of hypotensive (pre)syncope. Secondary aim regards the estimation of feasibility of this tool.

The main purpose of this study is to assess the reliability of a new cuffless patch BP monitor in detecting episodes of hypotensive (pre)syncope during tilt testing.

The number of cardiac implantable electronic devices (CIEDs) implanted each year has grown rapidly over the past two decades. CIED infections, defined as infections involving the generator implant site (pocket) and/or intravascular leads, have become increasingly prevalent, with the rate of growth in infections outpacing that of CIED procedures. The odds of both short term and long term mortality are at least doubled in patients who suffer CIED infections, and long term survival is particularly poor in women. Optimal strategies to prevent CIED infections in high-risk patients are largely unproven. However, recent observational studies of an antibiotic-coated envelope implanted at the time of CIED procedure have shown that this strategy is associated with a low incidence of CIED infections. Other interventions to prevent CIED infections, including the use of antibiotic irrigant used to wash the pocket during implantation and postoperative oral antibiotics, are commonly used but not supported by rigorous controlled studies. The Specific Aim of this study is to test the hypothesis that the use of the antibacterial envelope alone is noninferior to a strategy using the antibacterial envelope and intraoperative antibacterial irrigant and postoperative oral antibiotics for the reduction of cardiac implantable device infections in patients with ≥2 risk factors for infection.

The investigators hypothesis is that a significant number of patients may remain without specific cause and have recurrent syncope with its associated physical and mental morbidity.
