Prognostic value of left atrial functional parameters in patients with severe chronic heart failure and preserved left ventricular systolic function

The aim of study was to assess prognostic significance of left atrial (LA) functional parameters and levels of biomarkers in patients (pts) with severe chronic heart failure (CHF) and preserved left ventricular (LV) systolic function. Methods. Prognostic value of LA functional parameters, levels of BNP., NT-proBNP and high sensitivity C reactive protein (CRP) was assesed in 128 pts (age 63.2±1.7) with III-IV NYHA functional calss CHF and preserved LV systolic function (LV EF >50%). Results. During 37±0.8 months from cardiac causes died 43 (33.6%) pts. In Kaplan-Mayer analisys survival rate was 62, 63 и 64% in pts with levels of BNP >300 pg/ml, NT-proBNP ≥1500 pg/ml and CRP≥15 ng/ml and 85, 86 и 84% (p150 msec (63%) и Ar-A>-30 msec (62%), respectively. Conclusions: 1) LA functional parameters are powerfull independent predictors in pts with CHF and preserved LV systolic function. 2) Distribution of pts according to baseline levels of BNP
