Abstract
Background:
The aim of our study was to compare Euroqol-5D (EQ-5D) outcomes in coronary heart disease (CHD) patients with those from the general population. We aimed to identify those dimensions which were mostly impaired.
Methods:
EQ-5D results (both the dimensions and the EQ-5D visual analogue scale (EQ-VAS)) from a European sample (11 countries) of coronary patients were compared with published age- and gender-specific normative data.
Results:
EQ-5D outcomes differed across countries and gender. Overall, the age-adjusted EQ-VAS scores were significantly lower in coronary patients compared with the general population, both in males (mean difference (MD)= −5.24(−7.59 to −2.88)) and in females (MD= −8.32 (−11.69 to −4.95)). Coronary patients had a significantly higher risk to report moderate or severe problems related to anxiety/depression (odds ratio (OR) male=1.84 (1.14–2.95); OR female=3.20 (2.32–4.40)). Furthermore, female coronary patients reported more problems on the mobility (OR=2.00 (1.38–2.90)), usual activity (OR= 2.54 (1.81–3.57)) and pain/discomfort dimension (OR=1.73 (1.23–2.43)) whereas in males, a borderline significant OR was found on the mobility (OR=1.43 (0.97–2.11)) and usual activity dimension (OR=1.44 (0.94–2.20)). The difference between the general population and the CHD patients attenuated as age increased.
Conclusions:
CHD has a negative influence on patient’s self-reported health status, both the EQ-VAS as well as the EQ-5D dimensions (with the exception of self-care in both genders and pain/discomfort in males) were impaired. The relative impairment was the greatest in female patients and the differences in the proportion of reported problems diminished with increasing age. The EQ-5D instrument is appropriate in capturing problems related to anxiety/depression, pain/discomfort, mobility and usual activities. Within clinical practice, particular attention should be given to females and younger CHD patients.
