The Kansas City Cardiomyopathy Questionnaire is the most sensitive, specific, and responsive health-related quality of life measure for heart failure. The Kansas City Cardiomyopathy Questionnaire is a item, self-administered instrument that quantifies physical function, symptoms frequency, cardio,yopathy and recent changesocial function, self-efficacy and knowledge, and quality of life.
This instrument was developed and validated by John Spertus. In the KCCQan overall summary score can be derived from the physical function, symptom frequency and severitysocial function and quality of life domains. For each domain, the validity, lansas, responsiveness and interpretability have been independently established.
Scores are transformed to a range ofin which higher scores reflect better health status. For brevity, only the performance characteristics of the overall summary score are presented questionnaite this discussion. Validity refers to the degree to which an instrument measures what it is supposed to measure. Since the validity of each individual cardiomyopaathy has been independently established, all components of the summary score are considered valid representations of their intended domains.
acrdiomyopathy Reliability refers to the ability of a measure to produce consistent results when the measured phenomenon is unchanged. Responsiveness refers to the ability of a measure to track accurately a phenomenon when it does change.
Cardiology Research and Practice
Baseline and 3-month KCCQ overall summary scores were One is to examine the prognostic significance of KCCQ scores and the other is to benchmark score changes against clinical assessments of change.
To facilitate the interpretation of cross-sectional KCCQ scores, 1, patients assessed 3 months after a myocardial infarction complicated by heart failure were followed for 1 year survival and heart failure hospitalization. This figure describes the Kaplan-Meier curves for this study:. Among these patients, the magnitude and direction of change was as follows: The KCCQ change scores were exquisitely reflective of clinical changes in heart failure both in terms of its directionality improvement versus deterioration and proportion-al-ity of change magnitude — as revealed in this figure:.
For patients experiencing large, moderate and small deteriorations in their condition, KCCQ Overall Summary scores decreased by For those with no, small, moderate and large improvements in their heart failure, the KCCQ scores improved by 1. The mean change in KCCQ scores was significantly different for all categories of change compared to stable patients. Even those with small clinical deteriorations or improvements This suggests that a mean difference over time of 5 points on the KCCQ Overall Summary Scale reflects a clinically significant change in heart failure status.

An alternative approach to interpreting clinical changes is to appreciate the prognostic significance of changes in scores. These data suggest that a 10 point decline in KCCQ scores has important prognostic significance.
