The GRACE registry provides the opportunity to analyse management of acute coronary syndromes in the real word and the impact of hospital characteristics. In this setting, we compare the activity of a new coronary intensive care unit with regional data.
Methods: From January 2000 to December 2003, 376 eligible patients were involved (22% of regional inclusion). GRACE standard diagnosis were the following, for our centrer (for the cluster): ST elevation myocardial infarction 28% (37%), non-ST elevation myocardial infarction 32% (31%), unstable angina 33% (24%). Demographic characteristics were similar with a median age of 64 (vs 66) and a large majority of male (74 vs 81%). Medical history and cardiovascular risk factors were comparable. Predictors of hospital mortality were observed at the same rate: cardiogenic shock (3 vs 3%), congestive heart failure > Killip 2 (4 vs 4%), left ventricular ejection fraction (LVEF) lower than 40% (17 vs 16%), recurrent ischemic symptoms (8 vs 8%). Coronary artery bypass grafts were required in 5% (vs 2%).
Results: Drugs prescription rates were similar: aspirin at admission (95%) and at discharge (95%), betablocker at admission (70%) and at discharge (85%), statin at admission (< 30% in 2000, > 60% in 2003) and at discharge (< 60% in 2000 and > 80% in 2003), ticlopidin-clopidogrel at admission (< 20% in 2000 and > 40% in 2003), ACE inhibitor for LVEF < 40%, intravenous GPIIblIIa, and low molecular weight heparin (90%). Cardiac catheterisation (90%) and percutaneous coronary interventions (80%) were performed at the same rates in our center and in the cluster. Hospital death was similar (2 vs 4%). Discharge status was home for a large majority of patients (63 vs 76%). The median length of stay was five days and shorter than three days for patients with unstable angina.
Conclusion: Based on GRACE registry data, the present evaluation revealed that our new center offered evidence-based medical and interventional therapy in patients with acute coronary syndromes at the same level than experienced institutions with similar results for hospital death and length of stay.
