EVALUATION OF THE OUTCOMES OF STABLE ANGINA MANAGEMENT AFTER SELECTIVE PERCUTANEOUS CORONARY INTERVENTION (PILOT RESULTS)

Aim. To evaluate the possibility for electronic data collection about the patients with stable angina after selective percutaneous coronary intervention (PCI) (angioplastics with coronary arteries stenting) in FSBI Almazov Center. To perform the study of life quality and patients satisfaction by PCI results in real clinical setting.

Material and methods. The questionnaire developed, that includes valid Russian language versions of Seattle Angina Questionnaire (SAQ) and EQ5D-5L. The questionnaires are filled by patients at admission for selective PCI, at discharge, in 1 week, 1, 6 and 12 months post discharge. After the discharge from hospital the questionnaires are mailed via e-mail or the data is collected by phone calls. Study is funded by Russian Science Foundation (project ID 17-15-01177).

Results. From 01.01 to 30.042017 the PCI was done in 558 patients (70,7% males) at the age 64,9±9,6 y.o. Informed consent was signed by 59%, of those less than 1% use e-mail. By EQ-5D-5L the points were: baseline 64,4±19,6, at discharge 67,0±19,4, in 1 week 67,7±17,6 and 1 month 63,3±19,2. By SAQ, in 1 month the patients noted increased physical activity, stability of angina, better life quality and decrease of angina severity. In 1 week and 1 month the unsatisfied by their treatment were 19% and 13% of patients, 68% and 69% noted high satisfaction by PCI results. The results of PCI matched the expectations in 78% and 79% patients, respectively.

Conclusion. At the information gathering, the response by e-mail is very low, that makes it necessary to collect data by phone. It is demanded to develop the methods for electronic data gathering (messages, mobile apps) for easier data collection and for feedback. The results of questionnaires processing showed non-matched data for different questionnaires to each other, that makes it to develop unified specific questionnaire with its further validization.
