Radionuclide equilibrium ventriculography was used to examine general and regional ejection fractions and velocity characteristics for both cardiac ventricles in 28 patients with occlusions of the aortic arch branches consequent to aortic arteritis of atherosclerosis. In nonspecific aortic arteritis (NAA) even young patients have myocardial dysfunction comparable to that in the elderly with atherosclerosis. However, as shown by the nitroglycerin test, these patients preserve functional reserves of the myocardium. Right ventricular hyperfunction observed in NAA patients may result from increased postload due to possible hypertension. The above myocardial shifts should be considered when deciding on reconstructive surgery on the aortic arch branches.
采用放射性核素平衡心室造影术检查了28例因动脉粥样硬化性主动脉炎导致主动脉弓分支闭塞患者的两个心室的整体和局部射血分数及速度特征。在非特异性主动脉炎(NAA)中,即使是年轻患者也存在与老年动脉粥样硬化患者相当的心肌功能障碍。然而,正如硝酸甘油试验所示,这些患者保留了心肌的功能储备。NAA患者中观察到的右心室功能亢进可能是由于可能的高血压导致后负荷增加所致。在决定对主动脉弓分支进行重建手术时,应考虑上述心肌变化。
