Active clinical trials for "Heart Arrest"

After successful resuscitation from certain types of cardiac arrest, total body cooling is now a well established treatment that improves the chances of the brain recovering. This however, has only been definitively proven after a certain type of cardiac arrest that is "ventricular fibrillation / ventricular tachycardia". The purpose of this study is to explore if total body cooling is beneficial for patients recovering from another type of cardiac arrest that is "pulseless electrical activity". HYPOTHESIS: Patients undergoing post-cardiac arrest therapeutic hypothermia have better neurological outcomes if their initial arrest rhythm is pulseless electrical activity (PEA) in comparison to asystole.

Therapeutic hypothermia after out-of-hospital cardiac arrest is considered as a standard care. However, optimal candidates, optimal dose, duration, timing of initiation and rate of rewarming is still unknown. The objective of this project is to improve the outcomes for patients after resuscitation from out-of-hospital cardiac arrest treated with therapeutic hypothermia established from the analysis of multicenter registry data.

Two-thirds of patients admitted to the Intensive Care Unit after a cardiac arrest die in the context of treatment withdrawal after a multimodal evaluation that determines an unfavorable neurological outcome. This study will evaluate the Pupillary Pain Index (PPI) in the neurological prognosis after cardiac arrest. The PPI is determined by recording of pupillary dilatation with a videopupillometer after a calibrated and incremented nociceptive stimulus on a cutaneous metamere.

This study was aimed to investigate the clinical characteristics, management and prognosis of patients developing intraoperative cardiac arrest during transcatheter aortic valve implantation

The primary hypothesis is that an ICD shock may be predicted days in advance by a combined score derived from different data obtainable from the ICD

The right side of the heart of often overlooked in patients who are acutely unwell, as the main area of focus when performing echocardiography tends to be the left ventricle. The right ventricle can yield important diagnostic clues that can aid the clinician, particularly in cases where one may suspect elevated right sided pressures, such as those due to a pulmonary embolus. Although it is taught that a dilated right ventricle is associated in patients with pulmonary embolus, but in patients with spontaneous circulation. What is unknown is patients who sustain a cardiac arrest, does the same hold true. There is a paucity of literature surrounding the appearance of the right ventricle in the cardiac arrest patient acutely. This study aims to assess right ventricular size and function in the immediate post cardiac arrest phase.

Define the frequency and survival pattern of cardiac arrests in relation to the hospital day of event and etiology of arrest.

This study evaluate the association of some in-ICU factors with the neurological prognosis of patients admitted for an out-of-hospital cardiac arrest due to a myocardial infarction.

The investigators hypothesized that pre-arrival instructions would increase the likelihood of bystanders performing Cardiopulmonary Resuscitation (CPR).
