RESUMO
BACKGROUND: The Italian network on acute coronary syndromes outcome (IN-ACS Outcome) study is a nationwide observational, multicenter study with the aim to describe clinical epidemiology, management, 30-days and one-year outcomes of ACS in Italy. METHODS: All consecutive patients admitted for ACS to 38 hospitals, between December 2005 and February 2007, were enrolled in the study. Patient in-hospital details and follow-up data at 30-days and one-year were collected using a web-based CRF and stored in a central database. RESULTS: A total of 6045 patients (age 68 ± 13 years) were enrolled: 2313 patients (38.3%) had ST elevation myocardial infarction (STEMI) and 3732 (61.7%) patients had NSTE-ACS. Primary PCI was performed in 1085 (46.9%) STEMI patients, thrombolysis in 590 (25.5%) patients, whereas 638 (27.6%) patients were not reperfused. Among patients with NSTE-ACS, coronary angiography was performed in 2797 (75%) patients, PCI in 1797 (48.2%) patients and CABG in 213 (5.7%) patients. Thirty-days and one-year mortality rates were 5.8% and 9.8%, in STEMI patients and 3.1% and 8.6%, in NSTE-ACS patients. CONCLUSIONS: The IN-ACS Outcome study showed that the management of ACS is still suboptimal. Although 30-days mortality is low, the one-year mortality is still substantial.

BACKGROUND: This study was designed to evaluate the biological significance of simultaneous changes in the circulating levels of osteoprotegerin (OPG) and TNF-related apoptosis inducing ligand (TRAIL) in patients with coronary artery disease (CAD), and, in particular, with acute myocardial infarction (AMI). METHODS: Total levels of OPG and TRAIL were measured by ELISA in patients with AMI (n=113), unstable angina (UA, n=21) and healthy controls (n=120). RESULTS: Since OPG was elevated during the acute phase (first 12-24-48h) after AMI and in patients with UA with respect to healthy controls, while TRAIL was decreased in acute AMI patients, CAD patients were characterized by an increased OPG/TRAIL ratio. Moreover, the OPG/TRAIL ratio was significantly (p<0.05) higher in the acute AMI patients who developed heart failure (HF) than in those who did not develop HF in the follow-up. CONCLUSIONS: An impaired OPG/TRAIL ratio after AMI is related to a higher risk of HF.

AIMS: A large number of descriptive data on patients with acute myocardial infarction are based on clinical trials and registries on non consecutive patients: these data may give only a partial picture on treatment delay, patient characteristics, treatment and outcome of acute myocardial infarction in the real world. METHODS AND RESULTS: The BLITZ survey prospectively enrolled all of the patients with acute myocardial infarction admitted in 296 (87%) Italian Coronary Care Units from 15-29 October 2001. Data on treatment delay, therapeutic strategies, duration of hospitalization and 30-day outcome were collected. One thousand nine hundred and fifty-nine consecutive patients (mean age 67+/-12 years, 70% males) were enrolled, 65% with ST-segment elevation (STEMI), 30% with no ST-segment elevation (NSTEMI) and 5% with undetermined ECG. The median delay between symptom onset and hospital arrival was 2h and 9 min with 76% of patients hospitalized within the sixth hour (26% within the first hour, 48% within the second). The median delay from hospital arrival to reperfusion therapy in STEMI was 45 min (IQR 26-85) for thrombolysis (50% of the patients) and 85 min (IQR 60-135) for primary angioplasty (15% of the patients). Coronary angiography was performed during hospital stay in 46% of the patients (STEMI 48%, NSTEMI 43%, undetermined AMI 35%), coronary angioplasty in 25% (STEMI 26%, NSTEMI 15%, undetermined AMI 13%) and coronary bypass in 1.4% (1%, 2.2% and 1% respectively). Twenty-two percent of the patients admitted to hospitals without cath-lab were transferred to a tertiary care hospital for invasive procedures. The overall median hospital stay was 10 days (IQR 7-12, STEMI 10, NSTEMI 9, undetermined AMI 11) and was not significantly different between hospitals with or without cath-lab (respectively, 9 and 10 days, P=0.38). After discharge and up to 30 days, coronary angiography was performed in 11% (STEMI 11%, NSTEMI 11%, undetermined MI 9%), angioplasty in 10% (STEMI 10%, NSTEMI 11%, undetermined MI 7%), bypass surgery in 7% (STEMI 5%, NSTEMI 11%, undetermined AMI 7%). The in-hospital and 30-day case fatality rates were 7.4% and 9.4%, respectively (7.5% and 9.5% for STEMI, 5.2% and 7.1% for NSTEMI, 18.2% and 21.2% for undetermined MI). CONCLUSIONS: Patients with acute myocardial infarction admitted to the Italian CCUs, are older than those represented in clinical trials. A high proportion of these cases has the chance to receive early reperfusion therapy. Short-term mortality is lower than expected for patients with STEMI, but higher than reported for NSTEMI.
