    Input: Background Cardiovascular disease ( CVD ) is the leading cause of death worldwide . Secondary prevention is essential , but participation rates for cardiac rehabilitation are low . Furthermore , current programmes do not accomplish that patients with CVD change their lifestyle in a way that their individual risk factors for recurrent events decrease , therefore more effective interventions are needed . In this study , the effectiveness of the Hartcoach-programme , a telephonic secondary prevention program focussing on self management , is studied . Methods / design A multicenter , r and omised parallel-group study is being conducted . Participants are 400 patients with acute myocardial infa rct ion ( STEMI , NSTEMI , ) and patients with chronic or unstable angina pectoris ( IAP ) . Patients are recruited through the participating hospitals and r and omly assigned to the experimental group ( Hartcoach-programme plus usual care ) or the control group ( usual care).The Hartcoach-programme consists of a period of six months during which the coach contacts the patient every four to six weeks by telephone . Coaches train patients to take responsibility for the achievement and maintenance of the defined target levels for their particular individual modifiable risk factors . Target levels and treatment goals are agreed by the nurse and patient together . Data collection is blinded and occurs at baseline and after 26 weeks ( post-intervention ) . Primary outcome is change in cardiovascular risk factors ( cholesterol , body mass index , waist circumference , blood pressure , physical activity and diet ) . Secondary outcomes include chances in glucose , HbA1c , medication adherence , self-management and quality of life . Discussion This study evaluates the effects of the Hartcoach-programme on the reduction of individual risk factors of patients with CVDs . Patients who are not invited to follow a hospital based rehabilitation programme or patients who are unable to adhere to such a programme , may be reached by this home based Hartcoach-programme . If positive results are found , the implementation of the Hartcoach-programme will be extended , having implication s for the management of many people with CVD.Trial registration Wu S-K , Lin Y-W , Chen C-L , Tsai S-W : Cardiac rehabilitation vs. home exercise after coronary artery bypass graft surgery : a comparison of heart rate recovery . Am J Phys Med Rehabil 2006;85:711–717 . Objective : The autonomic dysfunction is known to adversely affect clinical outcome in patients with cardiovascular disease , and exercise training has been shown to modify the sympathovagal control of heart rate . The purpose s of this study were to investigate the effect of cardiac rehabilitation on heart rate recovery in patients who received coronary artery bypass grafting ( CABG )  and compare the effect with that of a home-based exercise program . Design : Fifty-four male patients having undergone CABG were r and omly assigned to a cardiac rehabilitation exercise program ( n = 18 ) , a home-based exercise program ( n = 18 ) , and a control group ( n = 18 ) for 12 wks to evaluate the differences in heart rate recovery among groups . Results : Patients in the cardiac rehabilitation group had significant increases in heart rate recovery ( 19.1 ± 6.2 vs. 14.0 ± 5.4 beats/min , P = 0.022 ) compared with those in the control group . There were no significant differences in heart rate recovery between cardiac rehabilitation and home-based exercise groups ( 16.2 ± 4.8 beats/min ) or between home-based exercise and control groups . All three groups had significantly improved heart rate recovery compared with their baseline data ( P < 0.001 , < 0.001 , and 0.007 ) . Conclusion : Our results point out that a cardiac rehabilitation exercise program has a positive effect on heart rate recovery in patients having undergone CABG and is consistent with the autonomic improvement . Although the home-based exercise group did not reveal statistical significance s over those in the control group , it had comparable efficacy to that demonstrated in the cardiac rehabilitation group Background : There are increasing opportunities for MI patients to attend lay-led , community based generic self-management programmes via self-referral . Aims : To determine the effectiveness of the Expert Patient Programme ( EPP ) for MI patients who had completed CR using a r and omised controlled , wait-list design , with a nested qualitative study . Methods : The Intervention Group attends the EPP immediately after completing the baseline assessment ; The Control Group had the opportunity to attend the EPP after completion of the 4-month follow-up .  192 MI patients ( 72 % men ) completed baseline assessment ; 162 responded at follow-up . Telephone interviews were conducted with 10 male and 9 female Intervention group participants . Results : Intention-to-treat analysis revealed no statistically significant differences between the groups although a pattern of small improvements among the Intervention Group was observed over time . Interviews revealed that Intervention Group participants viewed CR as being more about instruction whereas the EPP was viewed as being more about discussion , mutual support , and goal setting . A gender difference emerged whereby male participants valued information exchange whereas female participants expressed a preference for emotional support and social interaction within the EPP context . Conclusion : The EPP appears to hold few benefits for MI patients who have attended CR OBJECTIVE To evaluate the effectiveness of a home-based cardiac rehabilitation ( CR ) program on post-coronary arteries bypass graft patients . METHODS This is a r and omized study conducted in King Fahd Armed Forces Hospital , Jeddah , Kingdom of Saudi Arabia between June 2008 and January 2010 . Forty-nine participants were r and omized to either a control group ( st and ard hospital treatment , n=21 ) or an intervention group ( home-based CR , n=28 ) . Data were collected before hospital discharge ( baseline test ) and repeated 6 months after hospital discharge ( follow-up test ) . RESULTS There were no significant differences between the groups in the body mass index , hemodynamics , serum fasting lipid profile , and Quality of Life question naire ( QoL ) ( p>0.05 ) , with differences in physical function and Hospital Anxiety and Depression Scales ( HADS ) ( p<0.05 ) at the baseline test . At the follow-up test , the intervention group showed greater improvement in health-related QoL and risk factors compared to the control group , with significant differences in fasting blood glucose , triglycerides , high density lipoprotein cholesterol , physical function , and both QoL and HADS question naires ( p<0.05 ) . The intervention group also demonstrated significant improvements in QoL , HADS , body mass index , heart rate , high density lipoprotein cholesterol and physical function ( p<0.05 ) , while significant differences were observed in the control group in heart rate , QoL and physical function ( p<0.05 ) . CONCLUSION The home-based CR program improves health-related QoL and risk factor profiles for patients following coronary arteries bypass graft to greater extent than the st and ard hospital care The purpose of this pilot study was to test the initial efficacy , feasibility , and safety of a specially design ed postacute care transitional rehabilitation intervention for cardiac patients .  Cardiac Transitional Rehabilitation Using Self-Management Techniques ( Cardiac TRUST ) is a family-focused intervention that includes progressive low-intensity walking and education in self-management skills to facilitate recovery following a cardiac event . Using a r and omized two-group design , exercise self-efficacy , steps walked , and participation in an outpatient cardiac rehabilitation ( CR ) program  were compared in a sample of 38 older adults ( 17 Cardiac TRUST , 21 usual care ) . At discharge from postacute care , the intervention group trended toward higher levels of self-efficacy for exercise outcomes than the usual care group . During the 6 weeks following discharge , the intervention group had greater attendance in outpatient CR and a trend toward more steps walked during the first week . The feasibility of the intervention was better for the home health care participants than for those in the skilled nursing facility . The provision of CR during postacute care has the potential to bridge the gap in transitional services from hospitalization to outpatient CR for these patients at high risk for future cardiac events . Further evidence of the efficacy of Cardiac TRUST is warranted BACKGROUND Peak oxygen uptake ( Vo(2peak ) ) strongly predicts mortality in cardiac patients . We compared the effects of aerobic interval training ( AIT ) versus moderate continuous training ( MCT ) on Vo(2peak ) and quality of life after  coronary artery bypass grafting ( CABG ) . METHODS Fifty-nine CABG patients were r and omized to either AIT at 90 % of maximum heart rate or MCT at 70 % of maximum heart rate , 5 d/wk , for 4 weeks at a rehabilitation center . Primary outcome was Vo(2peak ) , at baseline , after rehabilitation ( 4 weeks ) , and after 6 months of home-based exercise ( 6 months ) . RESULTS Vo(2peak ) increased between baseline and 4 weeks in AIT ( 27.1 + /- 4.5 vs 30.4 + /- 5.5 mL.kg(-1).min(-1 ) , P < .001 ) and MCT ( 26.2 + /- 5.2 vs 28.5 + /- 5.6 mL.kg(-1).min(-1 ) , P < .001 ; group difference , not significant ) . Aerobic interval training increased Vo(2peak ) between 4 weeks and 6 months ( 30.4 + /- 5.5 vs 32.2 + /- 7.0 mL.kg(-1).min(-1 ) , P < .001 ) , with no significant change in MCT ( 28.5 + /- 5.6 vs 29.5 + /- 5.7 mL.kg(-1).min(-1 ) ) . Quality of life improved in both groups from baseline to 4 weeks , remaining improved at 6 months . There were no changes in echocardiographic systolic and diastolic left ventricular function . Adiponectin increased between 4 weeks and 6 months in both groups ( group differences , not significant ) . CONCLUSIONS Four weeks of intense training increased Vo(2peak ) significantly after both AIT and MCT . Six months later , the AIT group had a significantly higher Vo(2peak ) than MCT . The results indicate that AIT and MCT increase Vo(2peak ) similarly in the short term , but with better long-term effect of AIT after CABG Background Coronary heart disease ( CHD ) is typically associated with many cardiovascular risk factors ( e.g. , elevated blood pressure ) , low health-related quality of life , depression , anxiety and psychological stress . Expressive writing ( EW ) has shown beneficial effects on such variables in both people from the community and in patients with a variety of chronic illnesses . However , no study to date has evaluated the physical and psychological effects of the expressive writing procedure on coronary patients referred to cardiac rehabilitation ( CR ) . Methods The clinical effectiveness of a 2-week disease-related expressive writing procedure ( writing about one 's deepest thoughts and feelings regarding the experience with heart disease ) compared with the st and ard writing task ( writing about one 's deepest thoughts and feelings about the most traumatic or negative event experienced in the life ) , a neutral writing condition ( writing about the facts regarding heart disease and its treatment ) and an empty control condition will be evaluated in a r and omized controlled clinical trial ( RCT ) with repeated follow-up measurements at 3 , 6 and 12 months after discharge from CR . The primary outcome is health-related quality of life ( SF-12 ) . Secondary outcome measures are depression ( BDI-II ) , anxiety ( BAI ) and post-traumatic growth ( PTGI ) . Furthermore , the study will explore the moderating effects of coping styles , type D personality , perceived emotional support and participants ' evaluative ratings of the writing interventions on the main experimental effects in order to identify sub-groups of patients showing different results . Discussion The WRITTEN-HEART study aims to explore and exp and the frontiers of the expressive writing research enterprise by investigating the feasibility , safety and clinical efficacy of brief and cost-effective  expressive writing interventions in patients with CHD referred to CR.Trial registration Clinical Trials.gov BACKGROUND Participation in cardiac rehabilitation  after acute myocardial infa rct ion is sub-optimal . Offering home-based rehabilitation may improve uptake . We report the first r and omized study of cardiac rehabilitation to include patient preference . AIM To compare the clinical effectiveness of a home-based rehabilitation with hospital-based rehabilitation after myocardial infa rct ion and to determine whether patient choice affects clinical outcomes . DESIGN Pragmatic r and omized controlled trial with patient preference arms . SETTING Rural South West Engl and . METHODS Patients admitted with uncomplicated myocardial infa rct ion were offered hospital-based rehabilitation classes over 8 - 10 weeks or a self-help package of six weeks ' duration ( the Heart Manual ) supported by a nurse . Primary outcomes at 9 months were mean depression and anxiety scores on the Hospital Anxiety Depression scale , quality of life after myocardial infa rct ion ( MacNew ) score and serum total cholesterol . RESULTS Of the 230 patients who agreed to participate , 104 ( 45 % ) consented to r and omization and 126 ( 55 % ) chose their rehabilitation programme . Nine month follow-up data were available for 84/104 ( 81 % ) r and omized and 100/126 ( 79 % ) preference patients . At follow-up no difference was seen in the change in mean depression scores between the r and omized home and hospital-based groups ( mean difference : 0 ; 95 % confidence interval , -1.12 to 1.12 ) nor mean anxiety score ( -0.07 ; 
    Output:
    
Multifactorial individualized telehealth and community- or home-based cardiac rehabilitation are effective alternative models of cardiac rehabilitation , as they have produced similar reductions in cardiovascular disease risk factors compared with hospital-based programmes .
While further research is required to address the paucity of data available regarding the effectiveness of alternative models of  cardiac rehabilitation in rural , remote , and culturally and linguistically diverse population s , our review indicates there is no need to rely on hospital-based strategies alone to deliver effective cardiac rehabilitation .
