Beginning from the epidemiology of coronary heart disease, the authors firstly analyze the pathology and pathophysiology of the infarcted heart. Back to the basic anatomy of heart muscles, the authors then review the development history of basic anatomy theory of heart muscle fibers, focusing mainly on the helical myocardial band theory. This part covers theories of evolutionary biology, developmental biology, and modern imaging evidence on cardiac structures, as well as the intrinsic link between structures and functions of the heart. The relation between cardiac geometry and function is analyzed with helical myocardial band theory. Then returning to clinical problems, the authors introduce the development of left ventricular reconstruction (LVR), the impact of helical myocardial band theory on LVR, current status and disputes of LVR, and future prospect of LVR.
