intervention (int1)
The course Program at the Feiring Heart Clinic will: Clinical examination and ergospirometric testing, optimizing both treatment and prophylactic medication. Promoting physical Activity, changes in lifestyle, dietary changes/weight reduction, smoking cessation. In the follow-up period the participants will be contacted and report regularly through a web-based secure program (MedAxess)(such as: Activity-, dietary- and smoking habits). Each participant will have their own Mentor, helping keeping up the motivation. They will also meet regularly at the local doctors Office which reports relevant parameters to the Project (such as weight, BP, Lipoproteins, blood glucose/HbA1C)
(No Intervention)
The participants in the Control Group will receive care as usual at their local Doctors Office

Principal investigator Dag Elle Rivrud, MD
Description Background It has been established that the major risk factors of coronary artery disease are modifiable risk factors. The international Case control study across 52 countries has identified that 90% of the risk of acute myocardial infarction in males and 94% in females were modifiable risk factors as smoking habits, presence of hypertension, diabetes mellitus, abdominal obesity, psychological and social stress and hyperlipidemia (1). It is well established that interventions to promote physical activity and dietary changes could have beneficial effect in the reduction of incidence of coronary heart disease (CHD) (2). Aim of the Study The research hypothesis is that for persons on medium to high risk of CHD an early intervention using lifestyle and drugs over a period of three years can reduce the patients risk to develop CHD as estimated by risk score and some established risk factors of CHD as secondary surrogate end points. Major End Point For the major end point change in NORRISK Score (3) a systematic review of the literature to estimate sample size for a power estimate was done in association with a pilot study to estimate the variability of the score. The outcome variable is difference in risk score between baseline and three years follow-up. Considering the analysis of the pilot study, the investigators estimated the variability of the score difference (delta) of NORRISK to be standard deviation = 6.18%. As the median age of this sample was 51 years it is considered a change in the probability of ten years cardiovascular death of 1.5% to be clinically interesting. For a power of 90% and a type-I error of 5% the study will need two times 358 patients. Accepting a 10% dropout in the actual population, the corrected sample size will be two times 394. A total of 800 patients, two times 400, could be enough to pinpoint substantial risk change between baseline and three years follow-up for the NORRISK score. Secondary end points The investigators have done an extensive research of the literature as far the effect of lifestyle intervention on different surrogate end points as change in Systolic Blood Pressure (SBP) and Diastolic Blood Pressure (DBP), weight in kg, change in waist circumference in cm and change in TG, HDL-, LDL- Cholesterol, and HBA1C. (4, 5, 6). From the literature the estimated change between baseline and one year of intervention are: 1. Change in weight for the intervention is - 4.2kg (SD=5.1) and in percent - 4.75 % (SD=5.4). For the control group it is - 0.8 kg (SD=3.7) and - 0.9% (SD=4.2). 2. Change in waist circumference in cm for the intervention is - 4.4 cm (SD=5.2) for the control - 1.3 cm (SD=4.8). 3. Change in serum lipid in mg/dl: Cholesterol mg/dl for the intervention - 5mg/dl (SD=2.8) for the control - 1.3 mg/dl (SD=2.8) HDL in mg/dl for the intervention 2 mg/dl (SD=7) for the control 1 mg/dl (SD=6) TG in mg/dl for the intervention -18 mg/dl (SD=51) and intervention -1 mg/dl (SD=60) 4. Change in BMI in percent after one year for the intervention group -6.7% and the control -1.4% according to (6)) Considering those figure from the literature for a power of 80% and a type - I error of 5% the investigators will need the following minimum sample size: - Change in weight in kg 2*27 = 54 patients, in percent 2*48 = 96 patients - Change in SBP and DBP in mmHg: SBP mmg 2*207 = 414 patients DBP mmg 2*318 = 636 patients - Change in BMI in percent 2*214 = 428 patients - Changes in Triglycerides (TG) 2*169 = 338 patients In this clinical trial there will surely be enough power with a sample size of' 2*220 = 440 patients for the major surrogate outcomes except for changes in Cholesterol and HDL. As the intervention time is longer than three years instead of one year, those power estimates could under estimate the "de facto" power at the end of the three years observation time. Study population Selection criteria All persons who are selected from the general practitioner physician (GP) offices in all Norway. This study use the NORRISK Score (3), a new guideline for prevention of CardioVascular Disease (CVD) that includes calculation of total risk. This new risk model based on updated Norwegian data, as the European SCORE function, overestimates the risk of fatal CVD in Norway. NORRISK for 10-year CVD mortality is presented. It includes gender, age, smoking and levels of systolic blood pressure and serum total Cholesterol. Ten - year risk estimates calculated from NORRISK fall between SCORE high- and low risk estimates and increase strongly with age. Very few persons below 50 years of age have a 10 - year risk above 5% (European limit for high risk). More than half of men aged 60 years have estimated risks above this limit, while only 7% of 60-year-old women exceed the limit. Even if the risk limit is reduced to 1% for younger age groups, very few women below 50 years of age have risks above the limit. NORRISK is more adapted to the current situation in Norway than the SCORE model and may be a useful and relevant tool in Norwegian clinical practice. Randomization procedure Patients will be randomized to intervention or usual care. Randomization will be in permuted block randomization with utilization of concealed opaque envelopes. Patient information At randomization the patient receives verbal and written information about the study. This information will be repeated verbally. The patients sign a formula "Consent to participate". Ethics Committee The committee may look into the database during the study to assess data quality and to evaluate the quality of end points. If necessary the inclusion period or follow up time could be prolonged. Recording of data All case report forms (CRF) will be kept for the analysis in Feiring Heart Clinic before their introduction to the database electronically. Evaluation of data All CRF's are checked centrally for validity and completeness. Disclosure of data and publication All information obtained as a result of the study will be regarded confidential until appropriate analysis and review is performed. The results will be published and presented internationally. As far authorship and contribution, the investigators will follow the recommendations from the International Committee of Medical Journal Editor (ICMJE)(www.ICMJE.org). After publication of the initial report, participating investigators may prepare and publish sub analysis. All sub studies must be approved by the steering committee. All participant investigators will be acknowledged by name in the main publication.The recommendations of the STROBE group will be followed all the way (7). Insurance All patients participating in the study are insured in accordance with the official Norwegian insurance regulations.
