    Input: AIMS AND OBJECTIVES To compare drug adherence to lipid-lowering therapy among out patients with coronary artery disease who received information via short message service , via short message service and Micro Letter , or via phone only .  BACKGROUND Messaging applications and short message service are commonly used internationally . However , little is known about how coronary artery disease out patients in China may benefit from receiving health education through these technologies . DESIGN R and om sampling method . METHODS Data were collected from March-December 2013 . Subjects from Chengdu City , China , were r and omised to three groups : short message service , short message service + Micro Letter , and phone ( control ) . Appointment reminders and health information were delivered to patients in accordance with design ations . After six months , adherence to statin prescriptions was compared among the groups by using the Morisky Medication Adherence Scale . Logistic regression analysis was applied to determine those independent variables that were related to adherence . RESULTS The short message service and short message service + Micro Letter groups had better cumulative adherence ( lower Morisky Medication Adherence Scale scores ) after six months than phone group , and the short message service + Micro Letter group had better cumulative adherence ( lower Morisky Medication Adherence Scale scores ) than the short message service group . Female sex , older age and marriage show positive associations with adherence . CONCLUSIONS Short message service and messaging applications , such as Micro Letter , are effective means of providing discharged patients with reminders and coronary artery disease-related health information . Implementation of a short message service + Micro Letter program can improve outpatient adherence to medication . RELEVANCE TO CLINICAL PRACTICE This research offers useful information to help medical staff design effective interventions to improve medication compliance among coronary artery disease patients Background —Delay from onset of acute coronary syndrome ( ACS ) symptoms to hospital admission continues to be prolonged . To date , community education campaigns on the topic have had disappointing results . Therefore , we conducted a clinical r and omized trial to test whether an intervention tailored specifically for patients with ACS and delivered one-on-one would reduce prehospital delay time . Methods and Results — Participants ( n=3522 ) with documented coronary heart disease were r and omized to experimental ( n=1777 ) or control ( n=1745 ) groups . Experimental patients received education and counseling about ACS symptoms and actions required .  Patients had a mean age of 67±11 years , and 68 % were male . Over the 2 years of follow-up , 565 patients ( 16.0 % ) were admitted to an emergency department with ACS symptoms a total of 842 times . Neither median prehospital delay time ( experimental , 2.20 versus control , 2.25 hours ) nor emergency medical system use ( experimental , 63.6 % versus control , 66.9 % ) was different between groups , although experimental patients were more likely than control to call the emergency medical system if the symptoms occurred within the first 6 months following the intervention ( P=0.036 ) . Experimental patients were significantly more likely to  take aspirin after symptom onset than control patients ( experimental , 22.3 % versus control , 10.1 % , P=0.02 ) . The intervention did not result in an increase in emergency department use ( experimental , 14.6 % versus control , 17.5 % ) . Conclusions —The education and counseling intervention did not lead to reduced prehospital delay or increased ambulance use . Reducing the time from onset of ACS symptoms to arrival at the hospital continues to be a significant public health challenge . Clinical Trial Registration — clinical trials.gov . Identifier NCT00734760 Background — Secondary prevention by risk factor modification improves patient outcomes , yet it is often not achieved in clinical practice . Reasons for failure stem from challenges of prioritizing risk factor reduction and engaging patients in changing their behaviors . We hypothesize that a novel telemedicine intervention with tailored patient education could improve cardiovascular risk factors . Methods — To evaluate this intervention , we propose enrolling 450 patients with a recent myocardial infa rct ion and hypertension into a 3-arm r and omized , controlled trial . The first arm ( n=150 ) will receive home blood pressure ( BP ) monitors plus a nurse-delivered , telephone-based tailored patient education intervention and will be enrolled into HealthVault , a Microsoft electronic health record platform . The second arm ( n=150 ) will also receive BP monitors plus a tailored patient education intervention and be enrolled in HeartVault . However , the patient education intervention will be delivered by a Web-based program and will cover topics identical to those in the nurse-delivered intervention . Both arms will be compared with a control group receiving st and ard care ( n=150 ) . All participants will have an in-person assessment at baseline and at completion of the study , including st and ardized measurements of BP , LDL cholesterol , and glycosylated hemoglobin ( in diabetic subjects ) . The study design will allow assessment of a telephone-based , nurse-administered disease management program versus st and ard care . The main outcome of interest is the reduction in systolic BP in each intervention group compared with the control group at 12 months . Secondary outcomes assessed will include reductions in LDL cholesterol , body weight , and glycosylated hemoglobin , as well as adherence to evidence -based therapies and improvement in health behaviors . Conclusion — If successful in optimizing BP control , managing other coronary heart disease risk factors , and demonstrating a lower cost , the Web-based disease management tool has the potential to enhance coronary artery disease management , quality of care , and ultimately , patient outcomes . Clinical Trial Registration — URL : http://www . clinical trials.gov . Unique identifier : NCT00901277 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 BACKGROUND Recent clinical trials have shown that modification of plasma lipoprotein concentrations can favorably alter progression of coronary atherosclerosis , but no data exist on the effects of a comprehensive program of risk reduction involving both changes in lifestyle and medications . This study tested the hypothesis that intensive multiple risk factor reduction over 4 years would significantly reduce the rate of progression of atherosclerosis in the coronary arteries of men and women compared with subjects r and omly assigned to the usual care of their physician .  METHODS AND RESULTS Three hundred men ( n = 259 ) and women ( n = 41 ) ( mean age , 56 + /- 7.4 years ) with angiographically defined coronary atherosclerosis were r and omly assigned to usual care ( n = 155 ) or multifactor risk reduction ( n = 145 ) . Patients assigned to risk reduction were provided individualized programs involving a low-fat and -cholesterol diet , exercise , weight loss , smoking cessation , and medications to favorably alter lipoprotein profiles . Computer-assisted quantitative coronary arteriography was performed at baseline and after 4 years . The main angiographic outcome was the rate of change in the minimal diameter of diseased segments . All subjects underwent medical and risk factor evaluations at baseline and yearly for 4 years , and reasons for all hospitalizations and deaths were documented . Of the 300 subjects r and omized , 274 ( 91.3 % ) completed a follow-up arteriogram , and 246 ( 82 % ) had comparative measurements of segments with visible disease at baseline and follow-up . Intensive risk reduction result ed in highly significant improvements in various risk factors , including low-density lipoprotein cholesterol and apolipoprotein B ( both , 22 % ) , high-density lipoprotein cholesterol ( + 12 % ) , plasma triglycerides ( -20 % ) , body weight ( -4 % ) , exercise capacity ( + 20 % ) , and intake of dietary fat ( -24 % ) and cholesterol ( -40 % ) compared with relatively small changes in the usual-care group . No change was observed in lipoprotein(a ) in either group . The risk-reduction group showed a rate of narrowing of diseased coronary artery segments that was 47 % less than that for subjects in the usual-care group ( change in minimal diameter , -0.024 + /- 0.066 mm/y versus -0.045 + /- 0.073 mm/y ; P < .02 , two-tailed ) . Three deaths occurred in each group . There were 25 hospitalizations in the risk-reduction group initiated by clinical cardiac events compared with 44 in the usual-care group ( rate ratio , 0.61 ; P = .05 ; 95 % confidence interval , 0.4 to 0.9 ) . CONCLUSIONS Intensive multifactor risk reduction conducted over 4 years favorably altered the rate of luminal narrowing in coronary arteries of men and women with coronary artery disease and decreased hospitalizations for clinical cardiac events BACKGROUND Increases in life stress have been linked to poor prognosis , after myocardial infa rct ion ( MI ) . Previous research suggested that a programme of monthly screening for psychological distress , combined with supportive and educational home nursing interventions for distressed patients , may improve post-MI survival among men . Our study assessed this approach for both men and women . We aim ed to find out whether the programme would reduce 1-year cardiac mortality for women and men . METHODS We carried out a r and omised , controlled trial of 1376 post-MI patients ( 903 men , 473 women ) assigned to the intervention programme ( n = 692 ) or usual care ( n = 684 ) for 1 year . All patients completed a baseline interview that included assessment of depression and anxiety . Survivors were also interviewed at 1 year . FINDINGS The programme had no overall survival impact . Preplanned analyses showed higher cardiac ( 9.4 vs 5.0 % , p = 0.064 ) and all-cause mortality ( 10.3 vs 5.4 % , p = 0.051 ) among women in the intervention group . There was no evidence of either benefit or harm among men ( cardiac mortality 2.4 vs 2.5 % , p = 0.94 ; all-cause mortality 3.1 vs 3.1 % , p = 0.93 ) . The programme 's impact on depression and anxiety among survivors was small . INTERPRETATION Our results do not warrant the routine implementation of programmes that involve psychological-distress screening and home nursing intervention for patients recovering from MI . The poorer overall outcome for women , and the possible harmful impact of the intervention on women , underline the need for further research and the inclusion of adequate numbers of women in future post-MI trials Background : Patient delay in seeking treatment for acute coronary syndrome symptoms remains a problem . Thus , it is vital to test interventions to improve this behavior , but at the same time it is essential that interventions not increase anxiety . Purpose : To determine the impact on anxiety and perceived control of an individual face-to-face education and counseling intervention design ed to decrease patient delay in seeking treatment for acute coronary syndrome symptoms . Methods : This was a multicenter r and omized controlled trial of the intervention in which anxiety data were collected at baseline , 3-months and 12-months . A total of 3522 patients with confirmed coronary artery disease were enrolled ; data from 2597 patients with anxiety data at all time points are included . The intervention was a 45 min education and counseling session , in which the social , cognitive and emotional responses to acute coronary syndrome symptoms were discussed as were barriers to early treatment seeking . Repeated measures analysis of covariance was used to compare anxiety and perceived control levels across time between the groups controlling for age , gender , ethnicity , education level , and comorbidities . Results : There were significant differences in anxiety by group ( p = 0.03 ) . 
    Output:
    
Individual causes of mortality were reported rarely , and we were unable to report separate results for cardiovascular mortality or non-cardiovascular mortality .
Although some health-related quality of life ( HRQoL ) domain scores were higher with education , there was no consistent evidence of superiority across all domains .
We found no reduction in total mortality , in people who received education delivered as part of cardiac rehabilitation , compared to people in control groups ( moderate quality evidence ) .
There were no improvements in fatal or non fatal MI , total revascularisations or hospitalisations , with education .
