Objective To evaluate the impact of cardiac rehabilitation on blood lipid level,blood pressure control,exercise endurance,cardiac function, quality of life and lung function in patients with hypertension and atrial fibrillation (AF). Methods This prospective cohort study enrolled 96 patients with AF and hypertension, who were randomly and evenly assigned to the conventional group and the cardiac rehabilitation (CR) group, both treated for at least 6 months. Research indicators included the levels of triglycerides (TG), total cholesterol (TC) and low density lipoprotein cholesterol (LDL-C); left atrial diameter (LA), left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDd), anaerobic threshold (AT), peak oxygen uptake volume per kilogram (PeakVO₂/kg), peak ventilation volume (VEpeak), stroke volume (SV), peak oxygen pulse (PeakO₂pluse), changes in blood pressure, 6 minutes walking distance, Borg Fatigue Scale score, Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) scores. Results At the 6th month of the treatment, the levels of TG, TC, LDL-C, systolic blood pressure (SBP), diastolic blood pressure (DBP) were significantly reduced (P<0.05) in both groups. However, there was no statistical difference among the three blood lipid indicators between the conventional group and the CR group after treatment (P>0.05). Blood pressure dropped significantly(P<0.05) in both groups, especially in the CR group. Meanwhile, after treatment, LA and LVEDd decreased significantly (P<0.05) in both groups, except LVEF. LA decreased significantly (P<0.05) in CR group, compared with conventional group. In addition, AT, PeakVO₂/kg, VEpeak, SV and PeakO₂pluse levels were significantly elevated (P<0.05) in CR group compared with the conventional group after the treatment. There was no significant difference (P>0.05) in the indicators above in the conventional group. Six minutes walking distance were significantly increased (P<0.05) in both groups at 6th month of treatment, compared with the conventional group, the CR group increased more (P<0.05). Borg Fatigue Scale score, SAS score and SDS score were significantly reduced (P<0.05) in CR group at 6th month of treatment, however, there was no statistical difference (P>0.05) in the conventional group compared with that before treatment. The scores above were significantly reduced (P<0.05) in CR group compared with the conventional group after the treatment. Conclusions Cardiac rehabilitation therapy dominated by moderate-intensity exercise intervention can reduce the blood lipid level of atrial fibrillation and hypertension patients, control the blood pressure, improve the left atrial and left ventricular structure reconstruction, increase the exercise endurance, improve cardiopulmonary function, reduce negative emotions and improve the quality of life.
