G. Furze et al. registered trial acronym – LAMP. All participants received care as usual from their GP and/or cardiologist. Figure 1 is a CONSORT diagram (Consolidated Standards of Reporting Trials) (Schulz et al. 2010) which shows the ﬂow through the study. Randomization and blinding Remote telephone randomization using computer generated allocation was undertaken by people not involved in the study. Study measures were obtained by either postal ques- tionnaire or by the research nurse who was not involved in the treatment. Baseline measures were obtained before ran- domization. Members of staff who delivered the treatments were not involved in data collection. Data entry was by automated scanner and all analyses were carried out blind to the randomization status. Participants Recruitment was from all patients, diagnosed with angina in rapid access chest pain clinic (RACPC) at a district general hospital in the north of England, who met the inclusion criteria. Inclusion Adults (aged 18+ years) with a diagnosis of angina following a positive symptom-limited exercise treadmill test in RACPC; does not have any exclusion criteria. Exclusion Need for urgent revascularization, exercise induced arrhyth- mias or loss of systolic BP greater than 20 mmHg during exercise stress testing, self-report of rapidly increasing num- ber and duration of attacks of angina; a score of 4 on the Canadian Angina Class or the New York Heart Association classiﬁcation of heart failure; life-threatening co-morbidities; documented psychiatric problems (other than mild to mod- erate uni-polar depression or a simple anxiety state); dementia or confusion. Sample size In the original study of the Angina Plan (Lewin et al. 2002) the mean change (SD) in angina frequency per week at 6-month follow-up for patients on the Angina Plan arm was – 2Æ98 (5Æ54), and for the control patients was 0Æ40 (5Æ97). This gives an effect size of 0Æ45. To detect a standardized difference of 0Æ45 between the treatment groups in frequency of angina, with 80% power and 5% two-sided signiﬁcance, required 158 participants to be included in the analysis. 2270 Details of the intervention and control arms Intervention arm The Angina Plan targets misconceptions about angina, and uses goal setting and pacing to increase activity and reduce risk factors. It includes a workbook and a relaxation pro- gramme on CD, and was introduced in a 45-minute inter- view by a lay facilitator during which misconceptions about living with angina were dispelled, and goals to increase physical activity and reduce behavioural risks for further heart disease were introduced. Stress management and other psychological issues were also raised (Figure 2 is a graphic representation of the ﬂow through the ﬁrst interview). Participants were shown how to record their progress, which was reported at follow-up in brief (10–15 minutes) telephone or home-visits, the number of which was negotiated between the facilitator and the patient. People who smoked were offered referral to the local Smoking Cessation Service. All lay facilitator follow-up was completed by 3 months after the initial interview. The facilitators were six lay people with experience of heart disease, either personally (myocardial infarction and revascularization) or as carers of people with heart disease. They were recruited via advert in the local press, and were employed by the local NHS Primary Care Trust. The lay workers were four women and two men who were trained face-to-face, in 40 hours over 4 weeks with additional homework. They were managed by a community cardiac rehabilitation nurse; had regular group and individual supervision and were able to contact the nurse for advice at any time. Control arm Control group participants attended the clinic of the Angina Nurse Specialist, where the diagnosis was discussed and risk factor advice given, with referral to agencies such as the Smoking Cessation Service where appropriate. Participants also received written information about their condition and risk factors from sources such as the British Heart Foundation.
