Objective To understand to what extent patients control resting heart rate one year after percutaneous coronary intervention (PCI), and explore the factors influencing control of resting heart rate. Methods A total of 232 patients after coronary intervention were followed up by telephone for 1 year, and resting heart rates were recorded before discharge, and 1,3,6,12 months post-PCI. Readmission and recurrence of cardiovascular and cerebrovascular events within one year after the operation were also documented. Results A total of 222 patients completed the study. The percentage of patients whose resting heart rate was controlled within standard range were 28.45%, 32.33%, 34.06%, 35.84%,and 33.33% at the 5 time points. The highest resting heart rate was (68.87±8.13) beats/min before discharge, and the lowest was (63.67±5.48) beats/min 6 months post-PCI. The readmission rate was 27.48%, and the recurrence rate of cardiovascular and cerebrovascular events was 24.32% one year after the operation. The control of resting heart rate at 5 time points was respectively treated as the dependent variable, and the results of logistic regression analysis showed that, smoking and diabetes influenced control of resting heart rate at 5 time points; β receptor blockers and systolic blood pressure weighed on control of resting heart rate at 4 time points; age, and heart rate control knowledge level weighed at 2 time points (before discharge, and 12 months post-PCI). Conclusion Overall resting heart rate control after PCI in patients with coronary heart disease needs to be improved. Medical staff are recommended to help patients quit smoking, lower blood pressure and control blood glucose levels. In addition, it is of significance to improve patients′ resting heart rate control knowledge level and medication compliance.
