Filter by:Quality of bystander cardiopulmonary resuscitation (CPR) affect patient survival. Quality of professional CPR on patients has not been studied in detail, but it is regularly reported that the quality when tested on manikins deteriorates dramatically within months after training. Automated direct feedback on CPR quality from manikins brings quality back within a couple of minutes. Similar feedback has been incorporated into a defibrillator which also monitors quality of CPR. We hypothesise that quality of professional clinical CPR improves with such feedback
Recent studies have suggested that arginine-vasopressin could be more effective in the treatment of cardiac arrests. The last published study did not outline obvious improvements in the prognosis of all cardiac arrests but pointed out a possible increased survival rate when arginine-vasopressin is associated with epinephrine. The aim of this study is to compare the efficacy of two successive injections of epinephrine (1 mg) with two successive injections of epinephrine associated with arginine-vasopressin (40 UI) in out-of-hospital cardiac arrests occurring in adult patients. The primary endpoint is the survival rate at hospital admission. The inclusion period lasts 18 months and 2416 patients are planned to be enrolled.
Intravenous epinephrine has been part of the guidelines for cardiopulmonary resuscitation since the start. It improves outcome in animal studies, but has never been investigated in a controlled study in humans. Epidemiologic data indicate that it is an independent negative predictor for survival. If this is true in a controlled randomized study, it could be due to effects of the drug itself or more likely due to reduced quality of chest compressions and ventilations due to the time spent on placing an I.V. needle and injecting drugs.
The study compares the effectiveness of two fully approved shock waveforms (monophasic and biphasic shock) commonly used to defibrillate (shock) patients with out-of-hospital cardiac arrest due to a highly lethal rhythm problem (ventricular fibrillation). The purpose of the study (hypothesis) is to determine if one waveform results in improved resuscitation, admission alive to hospital, and discharge alive from hospital compared with the other.
To evaluate whether T Wave Alternans can predict ventricular arrhythmias and sudden cardiac death (SCD) in a prospective epidemiologic natural history study. The prospective epidemiologic pilot study included 550 patients that had left ventricular dysfunction and no history of sustained ventricular arrhythmias. The primary hypothesis tested was whether there was an increased risk of having an arrhythmic event when T Wave Alternans was present in the patient. The secondary aims included comparing risk due to T Wave Alternans between the ischemic patients and non-ischemic patients and assessing whether T Wave Alternans remained an independent predictor of risk upon adjustment for other known risk factors for arrhythmic events such as ejection fraction, ventricular ectopy, NSVT, average NN interval, and RR interval variability. The study approach was a standard epidemiologic surveillance technique. The subject population consisted of individuals with Class I to III heart failure who will underwent a TWA and Holter monitor test and then were followed for up to two years or until arrhythmic events occured.
To determine whether the dietary intake of trans-fatty acids derived from partially hydrogenated unsaturated fatty acids measured through a biomarker are directly associated with the risk of primary cardiac arrest.
To determine whether treatment with antidepressant, anticonvulsant, and antiarrhythmic drug therapies having the potential for proarrhythmia increased the risk of primary cardiac arrest. The aim of the original grant, starting in 1990 and ending in 1994, was to determine whether use of diuretics for hypertension increased the risk of primary cardiac arrest compared to the use of other antihypertensive agents.
To measure survival to hospital discharge of patients with out-of-hospital cardiac arrest in community units (e.g., apartment or office buildings, gated communities, sports venues, senior centers, shopping malls) served by trained non-medical responders using automated external defibrillators (AEDs), an approach called Public Access Defibrillation, compared to units receiving the traditional optimum community standard of care (i.e., rescuers trained to recognize a cardiac emergency, call 911, and initiate CPR).
To determine whether drug treatment of asymptomatic ventricular arrhythmias in post-myocardial infarction patients reduced the incidence of sudden cardiac death and total mortality.
To determine whether hypertensive patients with ECG abnormalities and receiving hydrochlorothiazide diuretics were at increased risk of sudden death.
