In older Finnish men, eating a lot of eggs is linked to a small drop in the bottom number of their blood pressure reading, but it doesn't seem to affect the top number.

We analyzed one assertion about egg consumption and diastolic blood pressure in older Finnish men, and it supports the idea that eating more eggs is linked to a small decrease in the bottom number of their blood pressure reading. No evidence was found to contradict this. The same assertion noted that egg intake does not appear to affect the top number of blood pressure [1]. What we’ve found so far is limited to just this single assertion, which comes from a specific group — older Finnish men — and only looks at diastolic pressure, not systolic. The link described is small, and we don’t know if it’s due to eggs themselves or other habits common in this group. We also don’t know how long the effect lasts, or whether it changes with different amounts of eggs. Because only one assertion was reviewed, and no studies were included to show how this was measured or controlled, we can’t say whether this connection is strong, consistent, or applies to other people. The evidence we’ve reviewed leans toward a minor association between higher egg intake and lower diastolic blood pressure in this group, but it’s not enough to draw broader conclusions. If you’re an older Finnish man and eat eggs regularly, this one piece of information suggests your diastolic pressure might be slightly lower than expected — but it’s just one observation, and many other factors could be involved.
