The subjects of the study were men and women (n=418) suffering from myocardial infarction or angina pectoris and hospitalized in the Cardiological Clinic of Kaunas Medical University during May-June, 2001. In order to assess the possibility to apply measures of psychological rehabilitation in a hospital setting, patients were invited to participate in three group sessions of relaxation (achieved by visualizing certain images). Effectiveness of psychological intervention was assessed by measuring statements indicating presence/absence of type A behavior pattern, depressiveness, and anxiety. Blood pressure was measured twice during each session. 38.3% of men and 35.15% of women came to the first session, while all three sessions were attended by 14.2 and 7.8% of men and women, respectively. Patients did not participate due to subjective (negative attitude towards psychological measures) and objective (hospital regimen: treatment and diagnostic procedures, etc) reasons. Average age of participants of three sessions was 56.9+/-10.31 for men, and 64.4+/-8.91 for women (p<0.02). After three group sessions such indices of type A behavior pattern, depressiveness, and anxiety as nervous tension, impatience, being in a hurry, fatigue, worrying, pessimism, anxiety became lower as compared with those at the first session.
