Aortale Druckkurven
Journal für Hypertonie - Austrian Journal of Hypertension 2008; 12 (1): 7-13
Aortale Druckkurven bei junger gesunder Person (links) und älterem Patienten mit Hypertonie und Linksherzhypertrophie (rechts). Beim älteren Patienten ist die Fläche unter der systolischen Kurve (weiß), die ein Surrogat für die Nachlast
und damit den myokardialen Sauerstoffverbrauch darstellt, durch verfrühte und erhöhte
Pulswellenreflexionen erhöht. Im Gegensatz dazu ist die Fläche unter der
diastolischen Druckkurve (grau), die ein Surrogat der Sauerstoffversorgung des linken
Ventrikels darstellt, vermindert. Es resultiert, und zwar bemerkenswerterweise schon ohne das Auftreten einer Koronarstenose, ein Missverhältnis zwischen myokardialem Sauerstoffbedarf und -angebot. Keywords: Alter,

Preparation has been incubated with 4 mM cinnamate for 15 minutes before beginning of trace in right hand panel. Left and right hand panel from the same preparation. Gap represents 20 min. B. In Cl-- free solution (Cl- replaced by glucuronate one hour before testing the effect of simulated ischaemia) rate and extent of K+ accumulation are the same as in the presence of Cl-.

Measurement of Na+ with Na+ selective microelectrode during simulated ischaemia in an isolated pig coronary artery strip. Na+s did not change throughout the ischaemic episode, indicating a steady state of transmembrane Na+-movement during early simulated ischaemia in this preparation. In the presence of glibenclamide (50 microM), Na+ also remained unchanged. Left and
right hand panel from the same preparation. Glibenclamide added 20 minutes before beginning of trace on the right hand panel. Like in Figure 4, left and right hand panel from the same preparation Keywords: Arteria coronaria,

Guinea pig papillary muscle. Typical results when measuring K+ during an ischaemic episode. A. Experiment performed using an electrode bevelled with a 45° angle pushed too deeply into the preparation - penetrating approximately two or three layers of myocardial cells. Right handside panel: lack of effect of glibenclamide upon ischaemic K+ efflux in the same experiment, when microelectrode pushed too deeply into the tissue. B. Ideal experimental conditions: flat-tipped surface
microelectrode gently touching the preparation like in Figure 2. Glibenclamide (100 microM) prevents early ischaemia-induced K+ efflux. Keywords: Arteria coronaria,

Journal of Clinical and Basic Cardiology 1998; 1 (1): 43-51
Simplified diagram of different microelectrode tips during simulated ischaemia. Hatched area represents paraffin oil (P.o.), area underneath, marked with oval rings, represents myocardial or smooth muscle tissue (T). Between tissue and P.o. one can see the artificially created reduced extra-cellular space (ARECS). a. Electrode tip bevelled in a 45° angle not yielding ideal contact with the tissue surface, thus making contact with the paraffin oil. Under these conditions the hydrophobic carrier will instantly escape from the tip and the electrode does not give further readings. b. Elec-trode tip bevelled in a 45° angle pushed too deeply into the tissue causing cell damage. Cells will be
either damaged or destroyed causing a constant leak of K+(K+ ions represented by stippling) into the ARECS which, in turn, leads to faulty measurements: instead of ischaemia-induced K+ efflux caused by changed K+ conductance of the membrane the electrode measures changes resulting from damaged cells (c.f. Fig. 3). c. Electrode tip bevelled in a 90° angle (flat tip) ideally positioned in the ARECS. Only under these circumstances correct measurements of transmembrane K+ efflux induced by ischaemia are possible (c.f. Fig. 3). d. Ideally bevelled surface microelectrode, impaled too deeply into the tissue. Stippling represents K+ ions leaking from damaged tissue - readings will be misleading. e. Too fine-tipped microelectrode, pushed too deeply into the tissue. Leaking K+ from the damaged tissue like in b and d, represented by stippling and small arrows. Keywords: Arteria coronaria,

Journal of Clinical and Basic Cardiology 1998; 1 (1): 43-51
Experimental assembly used for simulating ischaemia. Fig. redrawn from Gasser & Vaughan-Jones (1990). Schematic diagram of perfusion chamber. Ion-selective microelectrode (in our experiments e.g. Na+, pH, K+- selective microelectrode) pressed gently on the surface of a pig coronary artery strip and recording specific ion concentration changes during ischaemia. Preparation is laid across four supports (micropins, 100 µm in diameter) and pinned on one end and attached to a force transducer at the other. Also shown are two electrodes for field Stimulation. The diagram illustrates an episode of simulated ischaemia, with the preparation immersed almost completely in a stationary pool of paraffin oil (heavy stippling) while perfusion of warm (37 °C) Tyrode (light stippling) continues at the base of the chamber. Dashed lines represent ligated areas as described in the Methods. Keywords: Arteria coronaria,
