Diuretic Vascular Filling in the Initial Management of Acute PE With Right Ventricular Dysfunction Normotensive

Study Overview
=================
Brief Summary
-----------------
Pulmonary embolism (PE) is a serious disease with frequent intra hospital mortality remains high. If anticoagulation is perfectly codified, the remainder of the initial management has been less studied. In particular, the conditioning Initial often involves systematic plasma volume of 250 to 500 cc, by analogy to other situations. But this treatment option is not based on factual data. In the right ventricular dysfunction that often accompany severe EP, volume expansion may instead be harmful, according to the law of Frank Starling. A retrospective study has recently shown a benefit of diuretic therapy in patients hospitalized for severe normotensive EP. The proposed study is interventional, prospective, multicenter, randomized, require to include 60 patients. The main objective of the study is the comparison of the troponin normalization period Ic (biomarker of right ventricular dysfunction) in patients hospitalized in the initial phase of a serious normotensive EP, between the 2 groups diuretic and filling Vascular. The primary endpoint is the time in hours standardization of troponin Ic. The secondary endpoints will be: the period of normalization of Brain Natriuretic Peptide (BNP) changes in echocardiographic parameters of right ventricular dysfunction a composite endpoint: cardiovascular death / cardiogenic shock / use of amines / use of thrombolysis.

Masking: None (Open Label)


Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: Furosémide<br>Furosemide: a dose of 40 mg IV bolus initially and live according to the diuretic response: possibility of 2nd Live IV bolus 40 mg if urine output <500 cc / 24 at the 4th hour. Establishment of an infusion G5 500cc% in vein custody. | Drug: Furosemide<br>* furosemide 40 mg bolus with second bolus to 4 hours so inadequate diuretic response defined as urine output <500cc<br>* Other names: diuretic vascular filling;|
| Active Comparator: NaCl 9% isotonic<br>Infusion of 500 cc of isotonic NaCl 9% in 4 hours and 1000 cc 24-hour peripheral vein. The filling is being used in an empirical in severe EP and this group is therefore the control group. | Drug: NaCl 9% isotonic<br>* normal saline 500 cc / 4 hours and 1 L / 24 hours<br>* Other names: fluid replacement;|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Time normalization hours Troponin Ic. | This is a direct assay on peripheral venous sampling, easy to collect, accurate and reproducible, made routines in biochemistry laboratories CHU Nice and Antibes CH. Assay kits are the same at the University Hospital of Nice and Antibes CH (BECKMANTM kit). The threshold of positivity of troponin is 0.07 ng / mL. | participants will be followed for the duration of hospital stay, an expected average of 12 hours |
