Evaluation of collateral growth was performed after completion of the protocol by a simple functional test: total coronary occlusion. The rationale for this procedure was that if collaterals were developed, then occlusion would not induce functional disturbances. Alternatively, if collaterals were not mature, then occlusion would cause hemodynamic disturbances. After the second measurement of coronary blood flow, the coronary occlusion was maintained, systemic hemodynamics were measured and also the number of arrhythmias. In animals without collaterals, coronary occlusion caused deterioration of systemic hemodynamics and arrhythmias, including premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation; in animals with well developed collaterals, no such adverse effects were noted. | We evaluated collateral growth after completion of the protocol by a simple functional test: total coronary occlusion.

[page 2110] procedure was that if collaterals were developed, then occlusion would not induce functional disturbances. Alternatively, if collaterals were not mature, then occlusion would cause hemodynamic disturbances. After the second measurement of coronary blood flow, we maintained the coronary occlusion (n=9 in control group, n=6 in anti-VEGF group) and measured systemic hemodynamics and the number of arrhythmias. In animals without collaterals, coronary occlusion caused deterioration of systemic hemodynamics and arrhythmias, including premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation; in animals with well-developed collaterals, no such adverse effects were noted. |
