[Evolution of strategies of revascularisation in acute coronary syndromes with ST elevation. Analysis of the data of RESURCOR].
The aim of this study was to describe the changes in strategy of revascularisation in acute coronary syndromes with ST elevation (ACS ST+) since setting up a health care network. The authors analysed the incidence of coronary angioplasty and of intravenous thrombolysis from a prospective permanent hospital register of patients with ACS ST+ in the three Northern Alps departments from october 1st 2002 to december 31st 2004. Respectively, 171 patients were enrolled in 2002 and 675 in 2003, and 588 in 2004. The use of percutaneous coronary intervention increased (57, 69, and 78% in 2002, 2003, 2004, p< 0.01) in relation to the increased use of immediate secondary percutaneous coronary intervention (27, 36, 43%, p< 0.01) although the use of primary percutaneous coronary intervention did not changed (30, 33, 35%, p= 0.17). These results were observed in hospitals with and without Percutaneous Coronary Intervention facilities. An increase in prehospital (49, 67, 68%, p= 0.02) and hospital thrombolysis (48, 68, 73%, p= 0.03) was only observed in patients managed in institutions without Percutaneous Coronary Intervention facilities. The average delay to arterial punction (120. 124, 100 minutes, p< 0.01) and to intravenous thrombolysis (40, 30, 25 minutes, p< 0.01) decreased during the same period. Patients with ACS ST+ more commonly benefit from coronary revascularisation at increasingly shorter intervals to treatment. This would seem to be related to the better coordination of practitioners after the implantation of a health care network.
