In brief: Top and bottom BP
Systolic pressure is the peak blood pressure generated by the heart when it contracts, assuming no outflow obstruction, in which case it's still the highest BP sen blythe circulation.
Diastolic pressure is the lowest BP recorded as the heart "relaxes" (not really), as supported by the aortic valve. Cardiac risk of future events increased by higher levels of both numbers.
