运动性心肌肥大的机理研究(综述)

运动性心肌肥大是运动训练中普遍出现的生理现象,其表现为心脏增大,心肌肥厚,心室壁增厚,心脏重量增加等现象.目前,对运动性心肌肥大属调节性、生理性肥大的认识渐趋一致,但其发生机制尚末完全阐明.根据文献报导,从血流动力学因素、神经内分泌因素(如儿茶酚胺、血管紧张素Ⅱ)、致心肌肥大因子、遗传因素等对心肌肥大机理作一综述.

The Study of Medanisms of Developing Exercise Induced Cardiac Hypertrophy

The cardiac hypertrophy induced by exercise is an ordinary physical phenomenon in exercise. It appears cardiac enlargement, cardiac hypertrophy, wall-ventricular hypertrophy, cardiac weight increasement and so on. At present, the recognization is agreed on that cardiac hypertrophy belongs to regulatory and physical cardiac enlargement. But its mechanisms are still not be stated clearly. A statement of the mechanisms about cardiac hypertrophy which involve factors of Hemodynamics, Neuroendocrine system (eg:Catecholamine, AngiotensionII),Hypertrophy, Heredity will be given from the documents and the reports.
