Abstract
OBJECTIVE
Describe the frequency of high degree atrioventricular block (HDAVB) in patients with unstable angina (UA), analyze the variables associated with their appearance and evaluate whether HDAVB is independently associated with increased mortality or increased length of ICU stay.
DESIGN
Retrospective descriptive study of patients with UA included in the ARIAM registry.
SETTING
ICUs from 129 hospitals in Spain.
PATIENTS
From June 1996 to December 2003 a total of 14,096 patients were included in the ARIAM registry with a diagnosis of UA.
MAIN VARIABLES OF INTEREST
Variables associated with the development of HDAVB, variables associated with the mortality of patients with UA, variables associated with the length of ICU stay of patients with UA.
RESULTS
HDAVB frequency was 1%. Development of HDAVB was independently associated with the Killip classification and the presence of sustained ventricular tachycardia or ventricular fibrillation. Crude mortality of patients was significantly increased when HDAVB was present (9% versus 1%, p < 0,001). When adjusted for other variables, HDAVB was not associated with increased mortality. Development of HDAVB in patients with UA was independently associated with an increase in the length of ICU stay (adjusted odds ratio 1.89: 95% confidence interval: 1.33-5.69).
CONCLUSIONS
Patients with UA complicated with HDAVB represent a high-risk population with an increased ICU stay.
