Elevated blood pressure (BP) is probably the most-important modifiable risk factor for cardiovascular disease (CVD). BP influences the development of CVD, even if levels of BP are well below the usual cut-off point that defines the presence of arterial hypertension. Adequate measurement of BP is the most-important requirement for the ...
