The Left Ventricular Dysfunction Questionnaire: Italian translation and validation
AbstractPatients affected by heart failure have a compromised quality of life (QOL) and in the last few years â€œhealth related quality of lifeâ€ has become an important outcome indicator for the evaluation of heart failure treatment. Methods: Translation into Italian of the Left Ventricular Dysfunction Questionnaire (LVD-36), a new, 36-item, disease-specific health status instrument for patients with congestive heart failure, and its subsequent validation by administration to 50 consecutive patients in our heart failure outpatient clinic. The Italian LVD-36 was compared to the â€œThe Minnesota Living with Heart Failure Questionnaireâ€ (MLHF). Results: The Italian version of the LVD-36 correlates well with MLHF for ejection fraction (EF), NYHA class I and II, etiology and therapy. Since, however, the LVD-36 has only one domain, it may be able to offer more synthetic information than MLHF about patientsâ€™ status. Conclusions: The Italian version of the LVD-36 appears to be a reliable instrument for assessing patientsâ€™ QOL and the degree of limitations imposed on them by the disease. It is short, clear and easy to complete. In patients with heart failure the LVD-36 correlates well with the MLHF and may be considered a new disease- specific instrument to estimate changes in health status, and an useful support in optimizing therapeutic options.
