Invasive coronary procedures were associated with a small improvement in physical health-related quality of life at 2 years, with younger, male, and more educated angina patients showing the greatest gains.

Do invasive coronary procedures and sociodemographic characteristics affect changes in health-related quality of life in patients with coronary heart disease?
Sociodemographic factors such as age, sex, and education significantly influence improvements in health-related quality of life following invasive coronary procedures in patients with angina.

BACKGROUND: Few studies have focused on the association between the sociodemographic characteristics of a patient with the change in health-related quality of life (HRQOL) following invasive coronary procedures, and the results remain inconclusive. The objective of the present study was to measure the temporal changes in HRQOL of patients with coronary heart disease, and assess how these changes are associated with invasive coronary procedures and sociodemographic characteristics. METHODS: This was a prospective study of 254 patients with angina pectoris and 90 patients with acute coronary syndrome. HRQOL was assessed with the multi-item scales and summary components of the SF-36, both 6 weeks and 2 years after baseline hospitalization in 1998. Paired t-tests and multiple regression analyses were used to assess temporal changes in HRQOL and to identify the associated factors. RESULTS: Physical components of HRQOL had improved most during the 2 years following invasive coronary procedures. Our findings indicated that patients with angina pectoris who were younger, male, and more educated were most likely to increase their HRQOL following invasive coronary procedures. When adjusting for baseline HRQOL scores, invasive coronary procedures and sociodemographic characteristics did not explain temporal changes in patients with acute coronary syndrome, possibly due to higher comorbidity. CONCLUSION: Sociodemographic characteristics should be taken into account when comparing and interpreting changes in HRQOL scores in patients with and without invasive coronary procedures.
Veenstra et al. (Mon,) conducted a cohort in Coronary heart disease (angina pectoris and acute coronary syndrome) (n=344). Invasive coronary procedures vs. No invasive coronary procedures was evaluated on Change in Physical Component Summary (PCS) score at 2 years (p=0.034). Invasive coronary procedures were associated with a small improvement in physical health-related quality of life at 2 years, with younger, male, and more educated angina patients showing the greatest gains.
