CHAMORRO, Claudio; GUIDI, Dominique; YANEZ, Fernando  and  CHAMORRO, Gastón. Cardiovascular Rehabilitation in patients following myocardial revascularization: factors associated to program success. Rev Chil Cardiol [online]. 2017, vol.36, n.3, pp.185-193. ISSN 0718-8560.


: Background: Cardiovascular Rehabilitation Programs (CRP) have been shown to produce be-neficial effects in patients with coronary artery disease.


to identify factors associated to CRP success in patients who underwent myocardial revascularization


67 patients who underwent coronary artery

bypass surgery (CABG) or percutaneous coronary artery angioplasty (PTCA) were evaluated for functional capacity by means of a standard 6 min walking test (6mWT), before and after completion of the CRP. Distance covered during the test was correlated with age, prior functional class, time employed to complete CRP, time from coronary intervention and CRP initiation, CRP duration and type of revascularization. In addition, patients referred for a 36 sessions CRP were compared to those referred to only 12 sessions.


67 patients met inclusion criteria. Overall, there was a 12% increase (511,4 to 573,4 m) in 6mWT distance (p<0.001). The greatest benefit was obtained with the 36 session CRP as compared to a 12 session CRP (20 vs 8% (p<0.002). Also, completion of a 36 session CRP between 10 and 13 weeks compared to 14 to 24 weeks revealed a greater benefit in the former group (19% vs 10%, respectively (p<0.003). There was no difference in 6minWT distance in 3 groups of age (extending from 49 to 85 years-old); In addition, time from intervention to initiation of CRP (before vs after 8 weeks), type of revascularization or functional capacity at the beginning of CRP showed any difference in 6mWT distance.


CRP is a highly effective intervention to improve functional capacity in patients following myocardial revascularization, more so when more sessions are employed and when at least 3 sessions per week are implemented. The program is equally effective in patients starting CRP early after revascularization, and benefit is independent from patient age.
