Heart Ejection Fraction

I am reading that anything about 75% is considered high...do you know if your blood pressure is high and your pulse is high will that make a higher ejection fraction....I was really stressed when the echo was done....and now I am scared that my heart is having problems...my echo show everything else as normal and it even shows that my ejection fraction they consider normal...what scares me as I been have some dizziness vertigo type symptoms the past couple of weeks...my echo was done in February
