AFAIK one is the pressure entering the heart and the other is the pressure exiting the heart.

Systole is when your heart pumps while diastole is when your heart rests and the pressure of blood at diastole thus measures the resistence to flow of blood in your blood vessels in your peripheral blood vessels in the absense of pressure from your heart (the pump) pushing blood through these vessels.
In reality, diastolic blood pressure is the one we try and control, and , infact, systolic blood pressure has only recently been amenable to treatment( Calcium blocker drugs). High systolic blood pressure in the absense of diastolic high blood pressure( = isolated systolic hypertension) is felt to represent a sign of hardening of arteries, especially in males. High Systolic BP in conjunction with well treated lowered diastolic BP is thought to be normal enough eg 160/70 type readings
So Diastolic BP, representing the pressure on your blood vessels while the heart isn't pumping ( at rest) is the critical one.In all truth a reading below 90 mmHG is desirable. High Blood pressure is often associated with symptoms such as pounding headaches etc, but in truth, high BP is without symptoms and usually discovered accidently. Its effects are usually long term..i.e. untreated you increase chances of stroke and the heart muscle will get thicker( muscle up) in response to the extra load of pumping it has to do.The heart relies alot on being thin walled in order for oxygen to reach all the cells and so enlarging the heart promotes less oxygen to the heart...possibly causing a heart attack.
Initial drugs developed in 1970s etc were very powerful and often caused dramatic drops in bp with fainting. In addition, they were poor at extending life as they caused increased cholesterol. Modern drugs tend to be weaker and target elements of high blood pressure that cause kidney failure or heart enlargement rather than producing textbook ideal blood pressure = systolic below 140...diastolic below 90. Thus often a combination of drugs are used and they effect on extending life of various combinations is always under trial in order to spot poor combinations or define the best combinations

The systolic arterial pressure is defined as the peak pressure in the arteries, which occurs near the beginning of the cardiac cycle; the diastolic arterial pressure is the lowest pressure (at the resting phase of the cardiac cycle).

Systole and diastole refer to the high and low points of arterial pressure, defined as a measure of the arterial force exerted against a 1 centimeter diameter column of Mercury at sea level and is express as Millimeters of Mercury displaced. As mercury is displaced by pressure, the height that the mercury column rises to, is recorded in millimeters. This millimeter reading are the numbers expressed by a blood pressure recording. So a common reading would be:
120 Millimeters of Mercury OVER 80 Millimeters of Mercury
The term, "Millimeters of Mercury" is considered redundant and is dropped by convention, resulting in that same reading being expressed as simply 120 over 80.
Systole refers to the maximum or highest measure, read at the height of left ventricular contraction as blood is forcefully ejected from the the heart.
Diastole refers to the minimum or lowest measure, read at the end of left ventriular rest immediately before the aortic valve opens and blood is ejected anew in the next cardiac cycle.
Pressure upon "entry into the heart" refers to Central Venous Pressure and has nothing to do with Systolic or Diastolic events.

Blood pressure is the force in the arteries when the heart beats (systolic pressure) and when the heart is at rest (diastolic pressure). It's measured in millimeters of mercury (mm Hg).
