BACKGROUND: Recent advances in drug therapy question as to the additional impact behavioral interventions may have on the prognosis of patients with clinically stable coronary heart disease (CHD). PURPOSE: The aim of the study was to evaluate the effects of a multimodal, behavioral intervention on myocardial perfusion (MP) and cardiac events, compared to standardized cardiologic care, in patients with stable CHD. METHODS:Seventy-seven CHD patients (age 54.2 +/- 6.9 years, male 87%) were randomly assigned to a behavioral intervention plus standardized cardiologic care (INT, n = 39) or standardized cardiologic care alone (CO, n = 38). MP was assessed by (201)Thallium MP-scintigrams (SPECT) at baseline, after 2, 3, and 7 years, respectively. Subsequent cardiac events (MI, PCI, CABG) were assessed using the cardiologists' charts. RESULTS:Sixty-five patients (84%) completed the study. In all patients, the course of MP was significantly better in INT analysis of variance (ANOVA group x time p = 0.001); this was also true for patients without subsequent PCI/CABG (ANOVA group x time p = 0.002). Incidence of cardiac events was significantly associated with INT (6 vs. 14; log rank test p = .047). CONCLUSION: The study suggests additional long-term benefits of a behavioral intervention on myocardial perfusion and cardiac events in patients with stable CHD compared to standardized cardiologic care only.
