Influence of long-term exercise training on carotid intima-media thickness in patients with mild-moderate hypertension / 心血管康复医学杂志

ABSTRACT

Objective: To observe influence of long-term exercise training on carotid intima-media thickness (IMT) in patients with mild-moderate hypertension. Methods: A total of 92 patients with essential mild-moderate hypertension were randomly divided into routine treatment group (n=46) and exercise group (n=46, received exercise training based on routine treatment) according to number table. All patients were followed up for one year, and the blood pressure, carotid artery diameter and carotid IMT were measured, compared and analyzed in two groups before and after treatment. Results: There was no significant difference in systolic and diastolic blood pressure before treatment between two groups (P＞0.05). Compared with baseline value, there were significant decrease in systolic blood pressure [(176.66±l1.78)mmHg vs. (130.89±13.01)mmHg], diastolic blood pressure [(101.43±6.41)mmHg vs. (81.71±8.45)mmHg], carotid artery diameter [(6.62±0.97)mm vs. (6.22±1.01)mm] and carotid IMT [(0.98±0.12)mm vs. (0.84±0.11)mm] in exercise group after one-year training (P<0.05 all), and they were all significantly lower than those of routine treatment group (P<0.05 all ). Conclusion: Long-term exercise training can effectively control blood pressure, decrease carotid artery diameter and carotid intima-media thickness.
