title: Myocardial protection via the coronary sinus.
abstract: BACKGROUND
  Recent reports on facilitated reperfusion therapy re-address interests in coronary sinus interventions (CSI). Patients in whom short time results have been reported earlier were re-evaluated, with the aim of gathering the long-term results of pressure-controlled intermittent coronary sinus occlusion (PICSO) generated in patients with acute myocardial infarction (MI) and revascularization.
  
  
  RESULTS
  Thirty-four patients with ST elevated MI, in whom complete revascularization was achieved, underwent primary thrombolysis with or without PICSO. Follow-up data from these patients were collected for at least 48 months. Immediate perioperative differences were observed for time to peak creatine kinase (CK), as well as cumulative CK. In addition, the time until reperfusion was considerably less than for the control group (p=0.014). Long-term data showed significant differences in reinfarction (p=0.015), as well as in major adverse cardiovascular events, between the 2 groups (p<0.0001).
  
  
  CONCLUSIONS
  These data, because of the wide interval between collection and current analysis, could have inherited historical bias. Nonetheless, they are also uniquely indicating the potential of CSI to induce not only immediate, but also clinically significant long-term, effects as an adjunct to reperfusion therapy. Therefore, CSI should be, once again, on the study agenda and be placed under contemporary and best-available scientific scrutiny.
