<<Table 2 about here>>
Figure 2 summarizes trends in health-related QoL at baseline, 1 month and 3 months after PCI using eight subscales. The scores of 6 out of 8 subscales including general health perception, physical functioning, energy/fatigue, bodily pain, role limitations due to physical health and emotional problems significantly increased at 1 and 3 months from intervention. The two other subscales, social functioning and emotional well-being had a drop in QoL after 1 month and tended to rise again after 3 months.
