Abstract:
Cardiovascular disease is the leading global cause of death. The most common type is Coronary Artery Disease [CAD], and the most effective treatment method is Percutaneous Coronary Intervention [PCI]. The purpose of this predictive research was to study the quality of life and predicting factors of quality of life among post percutaneous coronary intervention persons in the Sri Racha district of Chon Buri province. Probability sampling yielded 270 patients aged 30-70 with ischemic heart disease who had received PCI treatment at the outpatient department of Queen Savang Vadhana Memorial Hospital and Cardiovascular Center, Samitivej Sriracha Hospital, Sriracha District, Chonburi Province. Personal information data were collected via an interview; additional data came from the patient's medical records. Quality of life was assessed using the EQ-5D-5L questionnaire, the Self-care Behavior to Prevent Recurrence instrument, and measures of social support and community environment conducive to health promotion. The questionnaire's confidence level was in the range of 0.73-0.96. Data were analyzed by descriptive and inferential statistics, including multiple regression. The results showed that quality of life was very high, with a mean utility of .97 (SD = .06) when assessed by the EQ-5D-5L assessment. When directly assessed by the visual analog scale method, the quality of life mean was 76.96 (SD = 14.16). Factors that could predict the quality of life were left ventricular function after PCI (b= 0.298, p< .01), being male (b= 9.859, p< .01), self-care behaviors to prevent recurrence (b= 0.189, p= .012), community healthenhancing environment (b= 0.296, p= .008), number of risk factors (b= -1.974, p = .017), and period after PCI (b= 0.574, p= .022); together they explained 22.1 % of the variance (R 2 = .221, p< .001) The results of this research suggest that professional nurses or medical personnel, when caring for cardiovascular patients who are post-PCI, should be particularly attentive when caring for patients who are female, have low cardiac contractility, who have multiple risk factors or co-morbidities. They should strive to increase knowledge, understanding and self-care skills for patients and their relatives, and should be referred to community nurses for continuing care to promote health-related quality of life.
