国内外己对心脏收缩功能异常进行了大量的研究,尤其对冠心病的心功能研究。随着心导管术、超声心动图与多普勒以及核素对心功能的深入研究,逐渐发现在某些疾病中,如冠心病,舒张功能异常可能表现得更早,或比收缩功能的检测更敏感。 A great deal of researches have been done on cardiac systolic dysfunction at home and abroad, especially on the cardiac function of coronary heart disease. With cardiac catheterization, echocardiography and Doppler, and nuclide studies of cardiac function, it has been gradually found that in some diseases, such as coronary heart disease, diastolic dysfunction may be earlier, or more than the detection of systolic function More sensitive.
