最近世界卫生组织公布的死亡人数最多的10大疾病中,冠心病和脑血管疾病分别排在第1位和第3位,其死亡人数约为720万和560万,占10大疾病总死亡人数的52.24％,另外尚有大量因本病而早衰和致残者未统计在内。由此可见,心脑血管疾病确为人类健康的最大杀手。动脉粥样硬化是导致心脑血管疾病发生的重要原因。其发病机理有动脉壁内膜增厚、脂质沉积、细胞浸润等,中膜平滑肌细胞向管腔转移和填殖,继而细胞外基质增生并出现泡沫细胞,使动脉壁变成糜粥样结构,终致发生破裂或血栓形成,管腔阻塞和供血障碍。若发生于心脏冠状动脉则呈现冠心病的系列症状,发生于脑血管则呈现脑血管病的诸
Of the 10 major diseases with the highest number of deaths released by the World Health Organization recently, coronary heart disease and cerebrovascular disease ranked No. 1 and No. 3, respectively. The number of deaths was about 7.2 million and 5.6 million respectively, accounting for 10 deaths in total. Of 52.24%, in addition there are a large number of patients with premature aging and disability are not included in statistics. This shows that cardiovascular disease is indeed the biggest killer of human health. Atherosclerosis is an important cause of cardiovascular and cerebrovascular diseases. The pathogenesis of arterial wall intimal thickening, lipid deposition, cell infiltration, smooth muscle cells in the tunica media to the lumen and the proliferation, and then extracellular matrix proliferation and the emergence of foam cells, the artery wall into a porridge-like structure , Eventually resulting in rupture or thrombosis, lumen obstruction and blood supply disorders. If occurred in the heart of the coronary artery presents a series of symptoms of coronary heart disease occurs in the cerebrovascular disease is manifested in cerebrovascular disease
