To observe and evaluate the effects of enhanced external counterpulsation (EECP) or exercises instruction on relieving depression and anxiety in patients with coronary heart disease.
Patients with coronary heart disease were selected from Shenzhen Futian Hospital Cardiology Department within one year (Feb.2015-Feb.2016). All patients were given standard medical therapy for coronary heart disease and allocated into two groups -- EECP group and exercise group. EECP group (n=42) underwent EECP therapy (one hour each day, 36 hours in total) while exercise group (n=48) accepted instruction on two phases of physical exercises. Both two groups filled in Depression questionnary (PHQ-9) and Anxiety questionnary (GAD-7) before and after the 9-week intervention. Epidata3.0 and SPSS 20.0 were used in data analysis.
(1) Before the intervention both groups of patients showed no significant difference (P > 0.05) in age, gender composition, body mass index, cardiac functional grading, smoking history and combined hypertension and (or) diabetes and (or) hyperlipidemia. (2) Scores of PHQ-9 and GAD-7 in both groups after the 9-week intervention were lower than the scores before the intervention by self-comparison(P<0.05), which indicated both EECP and exercises instruction could relieve depression and anxiety in patients with coronary heart disease. (3) Statistics of each group before and after the intervention were analyzed respectively. Before the intervention, EECP group had more severe depression and anxiety with higher scores of PHQ-9 (t1=3.090, P1<0.05) and GAD-7 (t2=3.030, P2<0.05) than exercise group did.Differently, after the 9-week intervention, the scores of PHQ-9 (t1=-4.060, P1<0.001) and GAD-7 (t2=-3.390, P2<0.001) in EECP group were significantly lower than that in exercise group. It meant that patients in EECP group had lower degree of depression and anxiety.
Both EECP and exercises instruction can relieve depression and anxiety in patients with coronary heart disease, but the effects of EECP are better than that of exercises instruction.
