Interventions	DETAILS OF INTERVENTION: The supportive‐educative telephone program was an interactive program involving information exchange between patient and the cardiac rehabilitation NURSE specialist through a series of 4 to 6 telephone calls initiated by the nurse during the first 6 weeks home convalescent period. The program was designed to assist patients to gain knowledge and improve decision making and coping skills, thereby decreasing their anxiety. A first call was made early in the first week after discharge in which the time and number of subsequent calls was made. DETAILS OF CONTROL usual care: group and individual teaching during hospital stay, visit of self help group member, information about cardiac rehabilitation program. CO‐INTERVENTION? yes. DETAILS OF CO‐INTERVENTIONS: usual care. DELIVERY OF INTERVENTION Frequency: 4‐6. First time at day 3 after discharge. Period: 6 weeks. PROVIDERS: nurse. INTERVENTION QUALITY: good. FIDELITY/INTEGRITY: yes.
