When a blood pressure reading is taken, two pressure levels are measured: systolic (the pressure during a heartbeat) and diastolic (the pressure between heartbeats). These measurements are typically recorded as one number over the other (e.g., 120/80 mmHg) with both values represented in mill...

Blood pressure is a measure of the force of the blood being pumped through the arteries(动脉)and is determined by both the amount of blood being pumped and the resistance to pressure in the arteries. High blood pressure is a dangerous condition that has no clear symptoms and can easily go ...
Reports that the cutoff point widely quoted in determining safe and dangerous blood pressure levels should be lowered based on what scientists are learning about the effects of hypertension. Impact of hypertension on risk of heart attacks; Levels of blood pressure that will now be considered as '...

The process in which high blood pressure causesheartdisease is not completely understood. But now scientists at the Baker Heart and Diabetes Institute have found that high blood pressure caused by specific signalling from the brain promotes heart disease by altering stem cells with the bone marrow....
blood pressure drops slightly, especially at the beginning of pregnancy, and the heart rate is increased. While low blood pressure does not normally pose any risks for the expectant mother and the child, too high blood pressure can be dangerous for both.39A blood pressure of 140/90 mmHg is...
Actually, when patients talk about feeling stressed or having a headache when the pressure goes up, it is usually the stress or the pain from the headache that causes the blood pressure rise, not the other way around. Even if blood pressure increases to dangerous levels (180/110 mm Hg or...
There is no threshold blood pressure reading that can trigger organ damage. The diagnosis is made based on the symptoms that present in the patient. Historically, a blood pressure of 180/120 was considered dangerous and in need of treatment to lower it immediately. That is no longer the ...
