STI Combined to Valsalva Maneuver for the Diagnosis of Left Ventricular Dysfunction in COPD Exacerbations (STICOPD)

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.
Verified June 2015 by Nouira, University of Monastir.
Recruitment status was:  Recruiting

The aim of this investigation was to assess the value of Systolic Time Intervals (STIs) as a method of detecting Left Ventricular Dysfunction (LVD) in patients admitted to the ED for Acute exacerbations of chronic obstructive pulmonary disease (AECOPD) and whether STIs measured under Valsalva manoeuver (VM) could improve the distinction between patients with LVD and those without LVD.

Condition Intervention
Obstructive Chronic Bronchitis With Acute Exacerbation Device: STI measurements at baseline and under Valsalva maneuver

Study Type: Observational [Patient Registry]
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Target Follow-Up Duration: 1 Year
Official Title: a New and Non Invasive Method to Calculate STI ( Systolic Time Intervals) Combined to Valsalva Maneuver in Patient With Acute Exacerbation of COPD

Further study details as provided by Nouira, University of Monastir:

Primary Outcome Measures:
  • diagnosis of left ventricular dysfunction [ Time Frame: during the first day admission in emergency department ]
    Systolic time intervals measured at baseline and under Valsalva maneuver

Estimated Enrollment: 166
Study Start Date: September 2014
Estimated Study Completion Date: August 2015
Estimated Primary Completion Date: June 2015 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: STI measurements at baseline and under Valsalva maneuver
    STI measurements at baseline and under Valsalva maneuver
Detailed Description:
We included patients admitted to the ED for AECOPD. Measurement of STIs included electromechanical activation time (EMAT), left ventricular ejection time and EMAT/LVET ration. These were performed at baseline and during the first strain phase of the VM using a computerized phonoelectrocardiographic method. The diagnosis of LVD was determined on the basis of clinical examination, echocardiography and brain natriuretic peptide. The values of STIs were compared between patients with and without LVD ; their diagnostic performance was assessed using the area under receiver operating characteristic curve (AUC of ROC).
