Filter by:A double-blind, multi-centre, randomized, placebo-controlled, feasibility pilot trial in the prevention of new onset atrial fibrillation of critically ill patients admitted to an ICU.
To investigate the prognostic impacts of the atrial fibrillation burden (AFb) in acute myocardial infarction (AMI) patients who developed paroxysmal new-onset atrial fibrillation (NOAF) during the index AMI hospitalization.
Atrial fibrillation (AF) is a heart problem that causes an irregular heartbeat. It can cause the heart to beat more rapidly and reduce the heart's ability to pump blood around the body efficiently, causing heart failure. It also increases the risk of blood clots forming inside the heart. These clots may then be pumped out of the heart, through the blood vessels, to other parts of the body. This can cause strokes if the clots spread to the brain. AF is a common problem outside an Intensive Care Unit (ICU), where treatment is based on good, evidence-based guidelines designed to reduce the risk of problems like heart failure or strokes. Around 10% of patients treated in ICU develop atrial fibrillation as a complication of their underlying illness. Some patients will recover their normal heart rhythm before leaving the ICU, often with the help of some medical treatments. It is not known whether these patients will get AF again after leaving the ICU, or when this is likely to happen. It is also unknown whether patients who avoid AF whilst on the ICU may still be at high risk of developing it after they leave. This study will identify patients on the ICU who have no previous record of atrial fibrillation. These patients will be monitored whilst on the ICU to identify those who develop AF. Those patients who develop new onset AF will be monitored on the ward after leaving the ICU to see which patients have AF at this point. The heart monitoring will be repeated once the patients leave hospital, again to identify whether they have atrial fibrillation. Some studies suggest that AF during critical illness causes a long-term risk of recurrent AF and AF associated complications such as heart failure, stroke, and death. To understand how to minimise these risks in intensive care patients, we need to know how which patients who develop atrial fibrillation whilst in an ICU go on to have recurrent atrial fibrillation in hospital and in the community. These patients may benefit from interventions to reduce long term adverse events such as anticoagulation to reduce stroke risk.
Postoperative atrial fibrillation is a major complication of cardiac surgery, which could lead to high morbidity and mortality, increase duration of hospital stay and increase the cost of treatment. New-onset atrial fibrillation after cardiac surgery is considered as a multifactorial phenomenon. Amiodarone, the most commonly used drug for cardioversion, is limited in atrial fibrillation after cardiac surgery due to side effects such as hypotension, bradycardia, and extracardiac side effects. Nifekalant is a novel class III antiarrhythmic agent with short onset time. It is a pure potassium channel blocker, which generally does not cause hypotension and bradycardia. There have been several trials that proven efficacy of nifekalant in converting persistent atrial fibrillation. For atrial fibrillation after cardiac surgery, the effectiveness and safety of nifekalant compared to amiodarone have not yet been reported. The investigators plan to perform a clinical trial comparing nifekalant to amiodarone in new-onset atrial fibrillation after cardiac surgery patients with a primary outcome of cardioversion at 4 hours. Secondary outcomes will follow cardioversion at 90 minutes and 24 hours, maintenance time of sinus rhythm within 24 hours, average time to conversion to sinus rhythm, rate of hypotension, length of ICU stay, length of hospital stay and hospital mortality.
The purpose if this pilot study is to determine if a perioperative infusion of 0.2% ropivacaine via bilateral T3 paravertebral catheters can decrease the incidence of new onset atrial fibrillation following primary CABG and/or valve surgery and compare a number of secondary outcomes.
Prospective, randomized, open-label clinical trial studying the treatment of new onset atrial fibrillation in critically ill patients with septic shock. Patients will be assigned to rhythm vs rate control strategies with various outcome measures assessed.
This pilot study aims to assess the feasibility and safety of using an ILR to identify the incidence of recurrent AF after an episode of newly diagnosed AF. The study further aims to assess the risk of AF recurrence in this low risk population based on left atrial and left atrial appendage anatomic and functional indices in addition to the standardized clinical CHA2DS2-Vasc score.
The primary purpose of the study is to evaluate treatment of new onset atrial fibrillation in french ICU.
Purpose/Objectives: Severe sepsis and septic shock are a common cause of new onset atrial fibrillation (NOAF) in the intensive care unit. Development of NOAF in this setting can prolong length of stay and increase mortality. Amiodarone is the most commonly used agent used in this setting to control rate and rhythm. However, limited data exist detailing appropriate dosing in this setting. The primary objective of this study is to evaluate two amiodarone dosing strategies, a full loading dose versus a partial loading dose, in patients with new-onset atrial fibrillation (AF) due to severe sepsis or septic shock to assess the mean heart rate every 6 hours after initiation of amiodarone infusion to day 7 or death. Research Design/Plan: Consecutive patients admitted to the medical or cardiac intensive care unit at University Hospital with NOAF in the setting of severe sepsis or septic shock will be screened for study inclusion. Data will be collected and stored using Microsoft Excel or Access and analyzed with JMP 12.0 and SPSS. Methods: Patients aged 18 years or older who develop new-onset atrial fibrillation in the setting of severe sepsis or septic shock and in whom the medical team deems appropriate to initiate amiodarone therapy in will be considered for study inclusion. Patients will receive intravenous (IV) and oral (PO) amiodarone, as per the standard of care. Patients will be randomized to a certain quantitative loading dose strategy; either a full loading dose (≥ 5g IV or ≥10g PO +/- 20%) or a partial loading dose (<4g IV or < 8g PO). Clinical Relevance: With intensive care unit length of stay (ICU LOS) and mortality being twice as high in NOAF with sepsis as compared to septic patients without NOAF, the investigators ultimately aim to identify a management strategy that may minimize this morbidity and mortality while also minimizing exposure to a drug that may cause serious adverse effects.
