In claudication patients , SE is more effective than UE at improving maximal walking and claudication distances , yet there is no difference in general quality of life or patient-reported community-based walking .
BACKGROUND Supervised exercise ( SE ) is widely accepted as an effective therapy for intermittent claudication ( IC ) , but its use is limited by cost .
Unsupervised exercise ( UE ) represents a less costly alternative .
We assessed the comparative effectiveness of SE vs UE in patients with IC .
The effect of supervised exercise and cilostazol on coagulation and fibrinolysis in intermittent claudication: a randomized controlled trial.
BACKGROUND The prothrombotic , hypofibrinolytic state that develops in patients with intermittent claudication ( IC ) upon walking due to ischemia-reperfusion injury ( IRI ) of the leg muscles may contribute to the high incidence of life- and limb-threatening thrombotic events observed in this patient group . Treatments , such as angioplasty , that obtund the IRI also ameliorate the procoagulant diathesis . The effect on this diathesis of supervised exercise and cilostazol , both of which provide symptomatic benefit in IC , but without significantly obtunding IRI , is unknown . METHODS Thirty-four patients ( 27 men and 7 women ; median age , 67 years ; range , 63 - 72 years ) were r and omized to receive best medical therapy ( BMT ) plus supervised exercise ( n = 9 ) , BMT plus cilostazol ( n = 9 ) , BMT plus supervised exercise plus cilostazol ( n = 7 ) , or BMT alone ( n = 9 ) in a 2 x 2 factorial design . Thrombin-antithrombin complex and prothrombin fragments 1 and 2 , both markers of thrombin generation ; plasminogen activator inhibitor antigen and tissue plasminogen activator antigen , both markers of fibrinolysis ; ankle-brachial pressure index ( ABPI ) ; and initial and absolute claudication distance ( ACD ) were measured at baseline and then 3 and 6 months after r and omization . RESULTS At 6 months , when compared with receiving BMT only , supervised exercise and cilostazol result ed in improvements in ABPI of 18 % and 13 % and in ACD of 40 % and 64 % , respectively . The effects on ABPI and ACD of combining supervised exercise and cilostazol were additive . Supervised exercise , cilostazol , and supervised exercise combined with cilostazol had no significant effect on any of the four hemostatic markers . CONCLUSIONS Treatment of IC by supervised exercise or cilostazol results in significant improvements in ABPI and ACD but has no demonstrable effect on the prothrombotic diathesis . This suggests that supervised exercise and cilostazol , unlike angioplasty , are unlikely to have a long-term beneficial effect on the thrombotic risks faced by these patients
