ClinicalTrials.gov Identifier: NCT01729702
Recruitment Status : Completed
First Posted : November 20, 2012
Last Update Posted : March 26, 2014
Information provided by (Responsible Party):
French Cardiology Society

Brief Summary:
The primary purpose of this study is to demonstrate that changes in plasma levels of circulating neurohormones (mainly BNP and NT-proBNP), measured at rest and post-exercise correlate with exercise functional limitation (assessed by exercise peak VO2) and exercise ultrasonic parameters (as left ventricular filling, obstruction, and mitral regurgitation)

Condition or disease Intervention/treatment
1- Primary (Sarcomeric) Hypertrophic Cardiomyopathy 2- Obstructive Hypertrophic Cardiomyopathy 3- Non Obstructive Hypertrophic Cardiomyopathy Other: blood sample collection

Detailed Description:
The secondary purposes are to study the kinetics of secretions of natriuretic peptides, and their relationships with extent of MRI myocardial fibrosis with the degree of exercise functional limitation.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 131 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Diagnostic
Official Title: Evaluation at Rest and Exercise of Clinical, Ultrasonic and Neurohormonal Parameters in Hypertrophic Cardiomyopathies
Study Start Date : April 2009
Primary Completion Date : December 2013
Study Completion Date : December 2013

Arm Intervention/treatment
single group - consecutive patients Other: blood sample collection

Primary Outcome Measures :
  1. Plasmatic Neurohormonal measures: BNP - NT ProBNP - Troponine [ Time Frame: Day 1 at rest and during exercise ]
