Zusammenfassung: | ᅟ
The interaction between the heart and the arterial system (ventricular-arterial coupling - VA) is an important determinant of cardiovascular performance. Vascular stiffness (Ea) and left ventricular (LV) endsystolic stiffness (Elv) augment with age and in heart failure (HF). Beta blockers (BB) are recommended therapy for patients with HF. However, data about the effects of BB on VA coupling are scarce.
Aims of the Study: To assess
1) changes in VA after BB therapy; 2) interactions between VA and LV functions, 3) predictive factors influencing VA change.
Methods
Eight hundred seventy-seven elderly patients with HF (aged ≥ 65, NYHA ≥ II, LV ejection fraction (LVEF) ≤ 45 %), treated with BB according to the CIBIS-ELD protocol of up-titration, underwent Doppler echocardiography with clinical and laboratory assessment before and after 12 weeks of BB. VA coupling was calculated as Ea/Elv ratio.
Results
Ventriculo-arterial interaction improved after 12 weeks of BB in elderly patients with HF. Values of Ea significantly decreased from 2.73 ± 1.16 to 2.40 ± 1.01,
