CONCLUSIONS

The PCI method improved the overall health outcomes of patients with unstable angina, as illustrated by the increase in six out of eight aspects of the QoL assessment tool, SF-36. Only the patient’s mental well-being and social functioning QOL scores after PCI were lower than those of the baseline. Furthermore, demographic factors such as age, occupation status as well as place of residence were found to be significantly correlated with the improvement in patients’ quality of life after the treatment. Our findings suggest the delivery of appropriate rehabilitation care and other methods which could support the recovery of patients as well as improve their social functioning and mental health. It is also necessary to communicate about the harmful effect of residence facilities and occupational status on health improvement after the treatment in order to increase the knowledge and awareness not only of the patients but also of their caregivers and relatives. There would be further research needed to declare some factors that may be related to PCI outcome and to take more effective policy strategy to improve QoL of patients with UA.
