In the pandemic of diabetes mellitus (DM), there is no unified approach to making the final clinical and postmortem diagnoses of deaths caused by coronary heart disease (CHD), cerebrovascular diseases (CVD), and some other vascular catastrophes. The acute and chronic forms of CHD and CVD and acute and chronic ischemic lesions in other vascular basins, which result in death in DM, should be regard as its complications. Moreover, DM is a peripheral vascular disease.
