| Popis: | The following Abstracts were omitted from the Abstract Supplement of the XVIIIth Congress of the European Society of Cardiology. To analyse left atrial (LA) systolic function in patients with congestive heart failure LA dimension (aortic-root echogram) and pulmonary capillary wedge pressure (PCWP) (balloon-tipped flow-directed catheter) were simultaneously recorded in 23 patients E.F. (33·4±9·1), (18 with ischaemic heart disease and 5 with dilated cardiomyopathy). Methods: LA pressure-dimension curve was constructed and was composed of 2 loops the A loop (expressing the pump function of the left atrium) and the V loop (expressing the reservoir function). The area of A-loop (AAL, in mm.mmHg) which reflected LA stroke work and the area of V loop (AVL) were measured. The difference between these (AAL-AVL, in mm mmHg) which reflected net atrial work was calculated before and after esmolol (E) administration, normal saline (S) infusion, dobutamine (D) and isosorbide dinitrate (N) administration. Results: AAL significantly increased after E (20·6±6·6 mm.mmHg, p |
