The development of atherosclerosis is a process of sequential events. Arrange the pathophysiological events in order of occurrence. Place the first event on top, and the last on the bottom.
Explanation & Rationale
This sequence starts with an injury to the arterial endothelium, leading to inflammation. Macrophages then consume LDL, forming foam cells. These foam cells release growth factors that stimulate the growth of smooth muscle cells. The smooth muscle cells grow over the fatty streaks, creating fibrous plaques. Finally, as these plaques grow, they narrow the vessel, which can result in ischemia. This is a simplified explanation of a complex process that involves many other factors and steps. It’s also important to note that this process can take many years to develop.
