NCT ID: NCT03232658 Recruiting - Clinical trials for Obstructive Sleep Apnea

The Severity Of Individual Breathing Cessation Events In Diagnostics Of Obstructive Sleep Apnea

Start date: March 1, 2018
Phase:
Study type: Observational

Obstructive sleep apnea (OSA) is a common nocturnal breathing disorder characterized by complete (apnea) and partial (hypopnea) breathing cessations during sleep. Currently, clinical diagnosis of OSA is based on the clinical symptoms, especially excessive daytime sleepiness, and apnea-hypopnea index (AHI) providing a limited overview of the breathing cessation event frequency during the night. Longer obstruction events and deeper desaturations have been suggested to be more harmful than shorter and shallower events and these individual characteristics are completely neglected by conventional and currently used AHI. The investigators have previously introduced novel diagnostic parameters incorporating the number, duration and morphology of individual obstruction events and shown that they improve the severity estimation of OSA compared to traditional measures. Even though, the novel diagnostic parameters have so far tackled some of shortcomings of AHI, they need to be refined to further increase the accuracy of the OSA severity estimation. It has been shown that age, body mass index (BMI) and sleeping position are strongly related to the severity OSA. However, it is not thoroughly studied whether the severity of individual obstruction events progress over time (the aging process) and which factors affect to this progression. It is known that OSA patients with similar AHI values, durations of individual breathing cessation events can differ significantly. Longer and deeper events are connected to increased mortality rate in patients with moderate or severe OSA and thus, could be considered to be more detrimental than shorter and shallower ones. However, it has not been thoroughly investigated whether in severe OSA patients with identical AHI values, sleep efficiency or hypertension is related to the severity of individual breathing cessation events. The investigators planned to explore, whether the individual breathing cessation event severity progress over time and how different confounding factors affect this progression. Furthermore, the correlation of EDS with the individual breathing cessation event severity, sleep structure, and frequency and occurrence of cortical arousals will be investigated. Also, the investigators will explore whether the percentage time of disturbed breathing from total sleep time is related to sleep efficiency or hypertension in severe OSA patients having similar AHI. Moreover, Positional therapy (PT) i.e., the avoidance of the supine posture during sleep is the treatment of choice for Positional Patients (PP) having most of their breathing abnormalities while sleeping supine. Since it is known that apneas/hypopneas are more severe while sleeping supine, this time the investigators will assess the therapeutic value of PT for severe Non Positional patients (NPP).

NCT ID: NCT03232398 Completed - Clinical trials for Acute Myocardial Infarction

Apixaban Versus Warfarin in Patients With Left Ventricular (LV) Thrombus

Start date: January 1, 2018
Phase: Phase 3
Study type: Interventional

Patients with acute ST-segment elevation myocardial infarction (STEMI) have an elevated risk of stroke, most of which are cardio-embolic in origin as a result of left ventricular (LV) thrombus formation. Anterior-wall location of a MI, in particular, can lead to the complications of LV aneurysm and/or thrombus, which some estimate occurs in approximately up to one-third of individuals within the first 2 weeks following an anterior MI. In the absence of anti coagulation, the risk of embolization in patients with a documented LV thrombus has been reported to be between 10 and 15 percent [3]. Although there are no randomized trials evaluating the efficacy of anticoagulation in patients with an LV thrombus after MI, observational studies provide substantial supporting evidence for the recommendation to anticoagulate patients with documented LV thrombus in order to reduce the risk of embolization. The observation that most events occur within the first three months from the MI forms the basis for the recommendation that anticoagulant therapy should be started early and continued for at least three to six months after myocardial infarction. Currently the practice guidelines recommend anticoagulation after MI only in certain settings such as the presence of LV thrombus or atrial fibrillation. To date there are no data on the use of novel oral anticoagulants (NOACS) for stroke prevention in the setting of LV thrombus after acute MI. The proposed aim of this randomized open label non inferiority clinical trial is to assess whether apixaban is as effective as VKA for the treatment of LV thrombus after acute ST segment elevation MI. Population: Patients with evidence of LV thrombus as assessed by trans-thoracic echocardiography (TTE) 3 to 7 days post admission for acute ST-elevation MI Intervention: The patients will be randomly assigned to treatment with apixaban or s.c enoxaparin 1mg/Kg BID followed by dose-adjusted warfarin to achieve a target international normalized ratio (INR) of 2.0 to 3.0 for 3 months. The study Outcomes are the presence of LV thrombus as assessed be echo, major bleeding, and stroke or systemic embolism and death from any cause.
