As an important means of treating heart failure (HF), cardiac assist device has been widely used in clinic. This paper reviews the application status, existing problems and future development trend of cardiac assist devices, including the classification of cardiac assist devices, representative research achievements and indications of the assist devices. It also summarizes the biomechanical indexes of the heart and the new approaches and methods for treating heart failure, as well as the hemodynamic studies of cardiac assist devices in recent years. The research findings provide references for further optimization of cardiac assist device structure and clinical application of the device.
心脏辅助装置作为治疗心衰的重要医疗器械，已经在临床上得到了广泛的应用。本文对心脏辅助装置的应用现状、存在的问题以及未来的发展趋势进行了综述，其中包括心脏辅助装置的分类、国内外代表性的研究成果、心脏辅助装置的适应证等，而且还对心脏的生物力学指标、心衰的生物力学因素、心衰的评价指标、近几年国内外心脏辅助装置的血流动力学研究以及治疗心衰的新方法等进行了分析总结，为进一步优化心脏辅助装置结构及其临床应用提供理论参考。.
