Global secondary prevention strategies to limit event recurrence after myocardial infarction: results of the GOSPEL study, a multicenter, randomized controlled trial from the Italian Cardiac Rehabilitation Network.
BACKGROUND Secondary prevention is not adequately implemented after myocardial infa rct ion ( MI ) . We assessed the effect on quality of care and prognosis of a long-term , relatively intensive rehabilitation strategy after MI . METHODS We conducted a multicenter , r and omized controlled trial in patients following st and ard post-MI cardiac rehabilitation  , comparing a long-term , reinforced , multifactorial educational and behavioral intervention with usual care . A total of 3241 patients with recent MI were r and omized to a 3-year multifactorial continued educational and behavioral program ( intervention group ; n = 1620 ) or usual care ( control group ; n = 1621 ) . The combination of cardiovascular ( CV ) mortality , nonfatal MI , nonfatal stroke , and hospitalization for angina pectoris , heart failure , or urgent revascularization procedure was the primary end point . Other end points were major CV events , major cardiac and cerebrovascular events , lifestyle habits , and drug prescriptions . RESULTS End point events occurred in 556 patients ( 17.2 % ) . Compared with usual care , the intensive intervention did not decrease the primary end point significantly ( 16.1 % vs 18.2 % ; hazard ratio [ HR ] , 0.88 ; 95 % confidence interval [ CI ] , 0.74 - 1.04 ) . However , the intensive intervention decreased several secondary end points : CV mortality plus nonfatal MI and stroke ( 3.2 % vs 4.8 % ; HR , 0.67 ; 95 % CI , 0.47 - 0.95 ) , cardiac death plus nonfatal myocardial infa rct ion ( 2.5 % vs 4.0 % ; HR , 0.64 ; 95 % CI , 0.43 - 0.94 ) , and nonfatal MI ( 1.4 % vs 2.7 % ; HR , 0.52 ; 95 % CI , 0.31 - 0.86 ) . A marked improvement in lifestyle habits ( ie , exercise , diet , psychosocial stress , less deterioration of body weight control ) and in prescription of drugs for secondary prevention was seen in the intervention group . CONCLUSION The GOSPEL Study is the first trial to our knowledge to demonstrate that a multifactorial , continued reinforced intervention up to 3 years after rehabilitation following MI is effective in decreasing the risk of several important CV outcomes , particularly nonfatal MI , although the overall effect is small .
