I have a family history of hemorrhagic stroke. No history of ischemic stroke, and very few heart attacks. Additionally, I think I personally have a low risk of heart attack from my lifestyle. That leaves a high risk of hemorrhagic stroke.
I have been looking at ways to lower my risk. The risk factors for hemorrhagic stroke (intracerebral hemorrhage) are often the exact opposite compared to ischemic stroke or heart attack. See references below.
Higher risk of hemorrhagic stroke:
- LOW Total Cholesterol
- LOW LDL
- HIGH HDL
- LOW Triglycerides
- LOW Protein diet
- LOW Saturated fat
Lower risk of hemorrhagic stroke:
- Egg consumption
- Animal protein
What's the best, safest, healthiest way to raise my LDL-C and Total Cholesterol?
I started eating more eggs and animal protein. Is there anything else I should do?
Thanks.

Fat and protein intakes and risk of intraparenchymal hemorrhage among middle-aged Japanese.

"Intake of animal protein tended to correlate inversely with risk; the relative risk with a one standard deviation increase in animal protein intake (17.6 g/day) was 0.79 (95% CI: 0.61, 1.02); p = 0.07. Results are similar to those recently reported for US women and together help to explain the high rate of this stroke subtype in Asian countries, where intakes of these nutrients are low."

"Low intake of saturated fat and animal protein was associated with an increased risk of intraparenchymal hemorrhage, which may help to explain the high rate of this stroke subtype in Asian countries. The increased risk with low intake of saturated fat and trans unsaturated fat is compatible with the reported association between low serum total cholesterol and risk."
