Your heart is about to explode and you die
If the systolic and diastolic numbers are close together, the patient has a narrow pulse pressure.
Diastolic, because it would lower the pressure.
Reduced blood flow ... but its usually an artifact of measurement rather than real.
When after contraction of ventricles of heart, blood is propelled into circulatory system (both systemic and pulmonary circulation) and that pressure is called systolic pressure, witch dilates the aorta and large(and small also) arteries. When ventricles relax in diastole aortic (and pulmonary) valves close down and then aorta and large (and small also)arteries contract, witch are dilated during systole. Peripheral resistance in closed system maintain the lower blood pressure called diastolic blood pressure.
It is not the maximum systolic pressure, but if close to that point.
It would depend on whether or not you had this reading on a fairly regular basis. The systolic number of 165 is higher than normal and should be evaluated by a doctor.
Systolic is when your heart is pumping, and diastolic is when the heart is at rest. Your diastolic pressure seems fine, however a systolic of 140 could mean you have isolated systolic hypertension. It would be worth it to speak to your doctor and see what you measures you can take to manage it.

It's due to the atmospheric pressures.
