Influence of Angiotensin Converting Enzyme (ACE) Genotype on Lung Diffusion in Heart Failure

This study has been completed.

In patients with chronic heart failure ACE-inhibitor treatment improves lung diffusion and prevents pulmonary edema after fluid overload. In the western country, 3 population types of ACE genotypes exist (DD, ID, II). It is unknown whether the ACE genotype influences the response to fluid overload in ACE-inhibitor treated chronic heart failure patients.

Condition Intervention
Heart Failure, Congestive Drug: isotonic saline infusion

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Prevention

Further study details as provided by Piergiuseppe Agostoni, Centro Cardiologico Monzino:

Primary Outcome Measures:
  • Possible identification of a genetic pattern responsible for different responses to ACE-inhibition during fluid overload in heart failure [ Time Frame: Third day ]

Secondary Outcome Measures:
  • Influence of ACE-genotype on exercise capacity [ Time Frame: Third day ]
  • Influence of ACE-genotype on lung function [ Time Frame: Third day ]

Enrollment: 100
Study Start Date: August 2006
Study Completion Date: December 2013
Primary Completion Date: December 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: CMPD patients
Patients with CMPD with evaluation of ACE I/D polymorphism
Drug: isotonic saline infusion

Detailed Description:
Patients with chronic heart failure in stable clinical condition treated with ACE-inhibitors, but not aspirin, will be evaluated by means of maximal cardiopulmonary exercise test and lung function including lung diffusion measurements. These tests will be done before and after rapid 500 ml isotonic saline infusion. Patients will be grouped according to their ACE genotype.

Inclusion Criteria:
