That doesn’t make sense...
High triglycerides cause plaque build up in the arteries, causing a narrowing, causing a clog = heart attack or stroke.
Aneurysms are a ballooning of the arterial walls (a weakness in the hose if you will). So this study says they’re simultaneously causing the clogging AND the ballooning of the arteries? Ehhhh... Maybe because the clogging causes HBP but that still doesn’t completely jive...
The first step is a structural compromise of the endothelial layer of the vasculature that protects the entire structure behind it. The endothelial layer is the teflon-like layer that faces our blood. This then allows the soft plaque formation that then later forms a hard plaque facing the bloodstream.
Yes, that location becomes narrowed if it went toward plaque formation, but this describes yet another handy option for destruction—it seemingly allows more protein in place of primarily Type 1, but some Type 3, collagen. I say this not from having read the study, but from understanding what happens with varicose veins and their immediate siblings, hemorrhoids. Those tissues are similarly expanded.
Compromise of the endothelial layer is the terrible first step, it seems.
I have an aortic aneurysm and low blood pressure. I typically run 105/53. It has been an issue most of my life. I stand up slowly to avoid getting dizzy or falling.
