[Comparison of data from registries of acute coronary syndromes RECORD and RECORD-2: management of patients and its results in noninvasive hospitals].

Positive changes are declared to occur during recent years in management of hospitalized patients with acute coronary syndromes (ACS) in Russia. Most of these changes are related to availability of invasive treatment. But considerable portion of patients (pts) are still treated in hospitals without facilities for invasive myocardial revascularization (noninvasive hospitals - NIHs). Aim of this study was to compare some characteristics of management of ACS in NIHs which participated in ACS registries RECORD (2007-2008, 8 NIHs from 6 cities; n=381) and RECORD-2 (2009-2011, 3 NIHs from 3 cities, n=680). Results. Groups of pts recruited in these NIHs had similar mean age and portion of women (67.6 and 66.5 years, 51.1 and 53.1 % in RECORD-2 and RECORD, respectively, p=0.64). Time from symptoms onset to hospitalization was shorter in RECORD-2 (3.2 vs 4.1 hours for ST-elevation [STE], =0.03; 4.0 vs 6.5 hours for non ST elevation [NSTE] ACS, <0.0001). Among RECORD-2 NSTEACS pts more had ST depressions (50.6 vs 28.7%, <0.0001), high risk of death according to GRACE score (39.1 vs 20.9 %, <0.0001), but less Killip class >II (15.0 vs 21.6%, p=0.025). No such differences existed among STEACS pts. Thrombolysis was more often used in RECORD-2 (62.6 vs 34.1%, <0.0001). Both STEACS and NSTEACS RECORD-2 pts more often received clopidogrel (63.5 vs 18.8%, p<0.0001, and 41.6 vs 11.1%, <0.0001, respectively). More NSTEACS RECORD-2 pts were given parenteral anticoagulants (93.4 vs 80.4%, <0.0001), low molecular weight heparins (23.4 vs. 3.4%, <0.0001) and fondaparinux (10.4 vs 0.7%, <0.0001), but still in 20% of NSTEACS RECORD-2 pts unfractionated heparin was given subcutaneously. Twenty RECORD-2 pts (2.9%) were transferred to invasive hospital but none during first 24 hours. There were no significant differences between registers in hospital mortality (20.0 vs 21.2%, =0.84; 4.2 vs 2.7%, =0.24 in STE and NSTE ACS pts of RECORD-2 and RECORD, respectively). Conclusions. Despite some improvement in management of pts occurring in 2-3 years NIHs mortality in STEACS remained very high. Numerically higher mortality in NSTEACS could be partially attributed to higher risk of RECORD-2 pts.
