[Adherence to guidelines on management of acute coronary syndrome in Russian hospitals and outcomes of hospitalization (data from the RECORD-2 Registry)].
Complete following existing guidelines for management of acute coronary syndrome (ACS) is known to be associated with better outcomes. Partly this is explained by lesser adherence to recommendations in high risk patients. Aim of our study was to assess relationship between degree of following current guidelines and in hospital outcomes independently from initial assessment of risk.
Each key recommendation from guidelines issued between 2008 and 2011 (13 for STE ACS, 12 for NSTE ACS) was given weight of 1. Sum of these units constituted index of guideline adherence (IGA). IGA was retrospectively calculated for 1656 patients included in Russian independent ACS registry RECORD-2 (7 hospitals, duration 04.2009 to 04.2011). The patients were divided into 2 groups according to quartiles of IGA distribution: 1) low adherence group (quartiles I-II); 2) high adherence group (quartiles III-IV).
In low adherence compared with high adherence group there were significantly more patients more or equal 65 years (=0.0007), with chronic heart failure [CHF] (
