Abstract


Background: According to the European Society of Cardiology (ESC) consensus, over 75% of patients with ST-elevation myocardial infarction (STEMI) should receive reperfusion therapy. An early invasive strategy is also advocated for high-risk non-ST elevation acute coronary syndromes (NSTE ACS). Until 2005, a single high-volume percutaneous coronary intervention (PCI) centre provided 24-hour service for the population of 3.2 million inhabitants in the Krakow Hospital Network Region. In August 2005 and December 2005 two additional round-the-clock duty PCI centres were launched in remote municipal hospitals (Tarnow and Nowy Sącz).
Methods: 29 non-PCI centres participated in the Registry of ACS in February-March 2005 (Period 1) and in December 2005-January 2006 (Period 2), so while Period 2 was conducted, three PCI centres provided 24-hour service for the Małopolska Region. Results: A total of 1404 patients with ACS were enrolled – 695 during Period 1 and 709 in Period 2. In comparison to Period 1, a non-significant trend towards more frequent mechanical reperfusion of STEMI patients with chest pain onset <12 hours was observed in Period 2 (54 vs. 60%; p=NS). A steep and significant rise was observed particularly among STEMI patients treated in non-PCI centres outside of the Krakow City Network (51 vs. 78%; p=0.001). In the newly established Tarnow and Nowy Sącz (eastern Małopolska) PCI networks the reperfusion rates for STEMI patients with chest pain <12 hours were 78% and 88%, respectively, in comparison to 55% in western Małopolska (p=0.001). The transfer rate for invasive treatment of NSTE ACS has increased from 13.8% in Period 1 to 19% in Period 2 (p=0.031) in the entire region. The in-hospital mortality for patients receiving conservative treatment in community hospitals has decreased among NSTE ACS patients (6.8 vs. 3.9%; p=0.045) and remained unchanged in STEMI (21.3 vs. 19%; p=NS).
Conclusions: Opening of new PCI centres, based on population magnitude and structure, improves local adherence to the guideline-recommended invasive approach in high-risk ACS patients. The Małopolska Programme model showed that one high-volume 24-hour duty PCI centre with a network of cooperating non-PCI centres for a population of 0.5 million might be sufficient to provide invasive treatment according to the ESC guidelines for eligible patients.
