Slide 5-

Development of atherosclerosis follows a predictable path from initiation phase to progression and development of lipid rich atheromatous plaque to complications leading to ischemic events Numerous risk factors for the development of coronary artery disease are common among patients, including obesity, smoking, dyslipidemia and hypertension Typical atherosclerotic plaque shows a well-formed necrotic core and overlying fibrous cap; smooth muscle cells, macrophages, lymphocytes, connective tissue components and calcification are variably present

Acknowledgement I'm extremely grateful to Professor Zi-Li Lv (吕自力) for making these microscopic slides available to us online. I’d also like to express my deepest thanks to Professor Gang Chen (陈罡) for his supervision and guidance. Finally, I would also like to thank colleagues and other teachers for their support and help.
