NCT ID: NCT03713333 Not yet recruiting - Hypertension Clinical Trials

Implementing Digital Health in a Learning Health System

ASE-INNOVATE
Start date: October 20, 2018
Phase: N/A
Study type: Interventional

The need for new models of integrated care that can improve the efficiency of healthcare and reduce the costs are key priorities for health systems across the United States. Treatment costs for patients with at least one chronic medical or cardiovascular condition make up over 4-trillion dollars in spending on healthcare, with estimations of a population prevalence of 100-million affected individuals within the next decade. Therefore, the management of chronic conditions requires innovative and new implementation methods that improve outcomes, reduce costs, and increase healthcare efficiencies. Digital health, the use of mobile computing and communication technologies as an integral new models of care is seen as one potential solution. Despite the potential applications, there is limited data to support that new technologies improve healthcare outcomes. To do so requires; 1) robust methods to determine the impact of new technologies on healthcare outcomes and costs; and 2) evaluative mechanisms for how new devices are integrated into patient care. In this regard, the proposed clinical trial aims to advance the investigator's knowledge and to demonstrate the pragmatic utilization of new technologies within a learning healthcare system providing services to high-risk patient populations.

NCT ID: NCT03712865 Enrolling by invitation - Clinical trials for Embolic Stroke of Undetermined Source

Thirty Day Heart Monitoring for Detection of Atrial Fibrillation Among Cryptogenic Stroke Patients

PROPhecy
Start date: November 19, 2015
Phase:
Study type: Observational

The PROPhecy study aims to detect the presence of atrial fibrillation/flutter in patients who have suffered an embolic stroke of undetermined source (ESUS) using 30 day cardiac monitoring. We hypothesize that the presence of any of the following features on long-term heart rhythm monitoring (holter monitoring) or heart ultrasound (transthoracic echocardiogram), either individually or in combination, will have additional predictive value for the detection of atrial fibrillation lasting 30 seconds or longer on 30 day holter monitoring: - greater than 100 premature atrial beats in 24 hours - greater than 2 runs of atrial tachycardia (4 or more non-sinus beats) in 24 hours - Left atrial enlargement on transthoracic echocardiogram

NCT ID: NCT03708471 Recruiting - Atrial Fibrillation Clinical Trials

Two-stage Hybrid Ablation or Thoracoscopic Epicardial Ablation for Long-standing Persistent Atrial Fibrillation

THAT-LSPAF
Start date: March 4, 2018
Phase: N/A
Study type: Interventional

Hybrid ablation, as an emerging strategy for atrial fibrillation (AF) in recent years, shows encouraging outcomes in many medical centers. A lot of cases demonstrated hybrid ablation has higher success rate than surgical ablation on patients with persistent AF, especially long-standing persistent AF (LSPAF). But it is still lack of high level evidence to prove it. This study focus on patients with long-standing persistent atrial fibrillation (LSPAF). In order to compare the efficacy and safety of hybrid ablation (two-stage) versus thoracoscopic surgical ablation, a randomized, controlled clinical trial will be performed in the population of LSPAF patients.

NCT ID: NCT03707873 Not yet recruiting - Clinical trials for Atrial Fibrillation and Flutter

Effect of Targeted Education for Atrial Fibrillation Patients

AF-EduCare
Start date: October 2018
Phase: N/A
Study type: Interventional

The aim of this study is to evaluate the effect of targeted in-person and online education on cardiovascular outcomes of AF patients (inpatient and outpatient), compared with standard care. Several other parameters (i.e. knowledge level, quality of life, symptom burden, self-care capabilities, adherence to oral anticoagulation, and an evaluation of the educational efforts) will be studied. Cost-effectiveness and cost-utility will also be investigated. The main research hypothesis is that individualized education based on the knowledge gaps measured with the JAKQ (Jessa Atrial fibrillation Knowledge Questionnaire) in each individual patient (called 'targeted education') is superior when compared to current AF care, both from an efficacy perspective (evaluated by different outcome measures) and from a cost-effectiveness perspective.

NCT ID: NCT03706677 Not yet recruiting - Clinical trials for Persistent Atrial Fibrillation

FIRE AND ICE II Trial Pilot

Start date: November 30, 2018
Phase: N/A
Study type: Interventional

The FIRE AND ICE II Trial (Pilot) is the pilot phase of a prospective, randomized, single-blinded, multi-center, interventional post-market clinical trial, comparing efficacy and safety of isolation of the pulmonary veins (PVI) using a Cryoballoon catheter or radiofrequency ablation with a ThermoCool® Smarttouch® catheter in subjects with persistent atrial fibrillation (AF).

NCT ID: NCT03703349 Not yet recruiting - Clinical trials for Coronary Artery Disease

Preoperative Oral Magnesium to Prevent Postoperative Atrial Fibrillation Following Coronary Surgery (POMAF-CS)

POMAF-CS
Start date: October 2018
Phase: Phase 4
Study type: Interventional

Post operative atrial fibrillation following coronary surgery (POAF) is a common complication that can affect 10-50% of patients. Intravenous magnesium, administered per-or post-operatively, reduces the incidence of POAF. However, the effect of preoperative magnesium loading on the incidence of POAF is not yet studied. 200 patients admitted for elective coronary surgery under Cardiopulmonary bypass will be included in this prospective randomized controlled trial. Treatment group will receive preoperative oral magnesium and control group will receive placebo for 3 days before the planned coronary artery surgery. The occurrence of POAF will be studied as a main outcome.

NCT ID: NCT03702582 Not yet recruiting - Stroke Clinical Trials

Rivaroxaban vs. Warfarin for Post Cardiac Surgery Atrial Fibrillation

NEW-AF
Start date: November 2018
Phase: Phase 3
Study type: Interventional

This prospective, randomized, active-controlled, parallel arm study compares the safety and financial benefits of arterial thromboembolism prophylaxis with Warfarin vs. Rivaroxaban (A novel oral anticoagulant) in patients with new onset atrial fibrillation after sternotomy for cardiac operations.

NCT ID: NCT03700307 Recruiting - Clinical trials for Persistent Atrial Fibrillation

Effects of Different Surgical Methods for Persistent Atrial Fibrillation Combined With the Application of Statin Drugs on Left Atrial Function

Start date: August 28, 2018
Phase: N/A
Study type: Interventional

A total of 164 patients with persistent atrial fibrillation, who are planned to undergo treatment with cryoballoon ablation, will be randomly allocated into two groups. These patients will receive circumferential pulmonary vein isolation, circumferential pulmonary vein and left atrial roof linear isolation using cryoballoon ablation(allocation ratio, 1:1). Patients in each group will be randomly allocated into the statin treatment group and non-statin treatment group (allocation ratio, 1:1). Real-time 3D ultrasound and 2D ultrasound examinations and measurement of left atrial function are carried out for all patients before the operation, and at 1, 2, 3 and 4 weeks and 2, 3, 6, 9 and 12 months after the operation. Preoperative transesophageal echocardiography will be carried out in all patients to measure the left atrial appendage function. All ultrasound data will be stored and a professional director from the ultrasound room will be invited for quantitative analysis. Indicators for ultrasonography include: left atrial anterior and posterior diameter, left atrial volume, left atrial volume index, mitral e ", E peak, A peak, velocity time integral (VTI), left atrial ejection fraction, left atrial strain, strain rate and left atrial appendage emptying velocity. Blood samples are extracted in all patients to detect routine blood, troponin I, D-D dimer, oral anticoagulant monitoring and other biochemical parameters such as blood lipids before the operation and at 1, 2, 3 and 4 weeks and 1, 2 and 3 months after the operation. This study will clarify whether these different operation methods have different effects on the recovery of postoperative left atrial function in patients with persistent atrial fibrillation, and whether changes in left atrial function are related to indicators such as inflammation, blood clotting and myocardial injury. Furthermore, this study will investigate whether the application of statin drugs can improve postoperative left atrial function by affecting these indicators. In addition, the operation method has been improved targeting at the disadvantage of the greater amount of X-ray exposure during cryoballoon ablation for persistent atrial fibrillation. Circumferential pulmonary vein isolation is combined with left atrial roof linear isolation´╝îand related indicators such as the success rate of the operation, intraoperative complications, postoperative recurrence rate and the amount of x-ray exposure are compared among two groups. At the same time, biochemical indicators of inflammation, blood clotting and myocardial injury such as blood routine, myocardial enzyme, troponin I and D-D dimmer are detected to analyze and determine which indicators are related to the postoperative recurrence of atrial fibrillation, the incidence of postoperative thrombosis and the recovery of postoperative left atrial function.
