OBJECTIVE: The aim of this study was to investigate the dynamic characteristics and changing trends of ambulatory blood pressure in patients with hypertension and coronary heart disease before and after percutaneous coronary intervention (PCI), and to determine the effects of PCI on the ambulatory blood pressure of patients with hypertension and coronary heart disease.
METHODS: A total of 126 patients with hypertension and unstable angina and who were hospitalized and received complete revascularization were enrolled in the study. The ambulatory blood pressure of the patients was monitored at three time points: 1-3 days before PCI (baseline), 3-6 days after PCI (1 week) and 1 month after PCI (1 month). The parameters between the time points were then compared using a t test.
RESULTS: Each ambulatory blood pressure index after PCI was not statistically different from those before PCI (P > 0.05). However, 1 month after the PCI, all ambulatory blood pressure indices significantly decreased and statistically differed from those before PCI (P < 0.01).
CONCLUSION: PCI can significantly improve the autonomic nerve function and ambulatory blood pressure indices of patients with hypertension and coronary heart disease.
