Cardiopulmonary Exercise Testing‐Guided Exercise Therapy in Hypertensive Patients: A Single Center Study

Abstract

Objective: To observe the effects of cardiac rehabilitation guided by cardiopulmonary exercise testing (CPET) on cardiorespiratory reserve function, blood pressure, blood pressure variability, and lipid metabolism in patients with hypertension.Methods: A randomized trial enrolled 67 Grade 1 hypertensive patients on antihypertensive drugs, divided into conventional (n = 35) and CPET (n = 32) groups. Antihypertensive drugs were not adjusted in both groups during the study period. Blood pressure, cardiorespiratory indicators, lipid profile, and BMI were assessed pre/post 12 weeks.Results: Postintervention, the CPET group exhibited significantly lower blood pressure levels and improved cardiac indicators compared to the conventional group (p < 0.05). CPET group showed greater improvements in cardiorespiratory endurance indicators (p < 0.05). The cardiorespiratory endurance indicators showed significantly greater increases in the CPET group compared to the conventional group (p < 0.05). Low‐density lipoprotein cholesterol (LDL‐C), total cholesterol (TC), triglycerides (TG), and body mass index (BMI) were significantly lower in the CPET group (p < 0.05).Conclusion: In addition to drug treatment, cardiac rehabilitation guided by CPET can effectively improve blood pressure control, reduce blood pressure variability, improve cardiorespiratory function and lipid metabolism, and increase exercise endurance in patients with Grade 1 hypertension. Its efficacy is clear and safe, with clinical value for promotion.
