左室肥厚是心脏对血液动力学负荷过重的反应。高血压患者左室肥厚开始是作为对抗周围阻力增加的代偿机制,但一定时间之后则产生不同程度的变化,这些变化损害心脏功能,降低冠脉储备,增加心绞痛、心衰、室性心律失常及猝死的发生率。本文分析18例高血压性心肌肥厚病人的平衡法核素心室造影心功能结果,并与正常人及无心肌肥厚者对比,旨在进一步探讨高血压性左室肥厚对左室功能的影响。
Left ventricular hypertrophy is the heart’s response to haemodynamic overload. Left ventricular hypertrophy in hypertensive patients begins as a compensatory mechanism to counteract increased peripheral resistance, but changes occur to varying degrees after a certain period of time, impairing cardiac function, reducing coronary reserve, increasing angina pectoris, heart failure, and ventricular arrhythmias And the incidence of sudden death. This paper analyzes the results of 18 patients with hypertensive cardiac hypertrophy by balanced method radionuclide ventriculocardiography cardiac function and compared with normal and no cardiac hypertrophy were compared to further explore the impact of hypertensive left ventricular hypertrophy on left ventricular function.
