title: [Prognostic value of the myocardial performance (Tei) index in patients with chronic heart failure].
abstract: Aim of this study was to define the prognostic value of Tei index compared with other clinical and instrumental parameters in elderly patients with chronic heart failure (CHF) observed in outpatient conditions. A total of 97 patients aged 60 to 85 years with symptoms of CHF NYHA class II--IV due to coronary heart disease or hypertension were included. Clinical examination, a 6-minute walk test, echocardiography with determination of Tei index were carried out. There was statistically significant difference between survival among patients with Tei index > or = 0.6 and patients with Tei index < 0.6 (p < 0.001). Among patients with preserved left ventricular ejection fraction (LV EF) survival of patients with Tei index <0.6 was higher compared to those with Tei index > or = 0.6 (p < 0.05). Independent predictors of acute myocardial infarction and mortality in elderly patients with CHF were detected. The greatest risk (odds ratio 11.6, 95% CI 2.50 - 53.70) compared with other clinical and instrumental parameters was associated with Tei index > or = 0.6. Among patients with preserved LVEF (LVEF > 45%) prognostic value of Tei index was similar to that of LV EF.
