*The predicted equation for EQ-5D health utility was derived from the general population 0.84822−0.00208× (age−50)−0.00002× (age−50)²−0.02090 if women.

†p Value was obtained using one sample t-test.

‡The predicted equation for VAS was 83.183−0.199 (age−50)−0.006 (age−50)²+0.401 if women.

ACS, acute coronary syndromes; EQ-5D, EuroQol five-dimensional questionnaire; PCI, percutaneous coronary intervention; VAS, visual analogue scale.
