Health-related quality of life: The impact of diagnostic angiography

Abstract

Background: Little is known regarding the effects of index angiograms on health-related quality of life related to angiographic outcome, that is, positive or negative for coronary heart disease (CHD).

Methods: A longitudinal, comparative design was used. Ninety-three patients underwent initial angiography and completed questionnaires (Cardiac-Quality of Life Index, Short Form-36 mental and physical, and Cardiac Attitudes Index) before, 1 week and 1 year after angiography. Data were evaluated with linear regression and analysis of variance.

Results: Fifty-five patients were CHD positive (age 65.3 ± 10.7 years, 49% were female), and 38 patients were CHD negative (age 59.5 ± 12 years, 53% were female). Compared with CHD-positive patients over 1 year, CHD-negative patients reported lower scores on the Cardiac-Quality of Life Index (P < .008), Short Form-36 mental and physical measures (P = .004), and Cardiac Attitudes Index (P = .05).

Conclusion: CHD-negative patients experienced lower health-related quality of life and lower perceived control than CHD-positive patients. After an index angiogram, a negative finding may not be sufficient to relieve negative emotions.
