What were the principle findings of the Framingham study?
Increasing blood pressure is associated with a progressive increase in the risk of stroke and CV disease
What numerical value of hypertension?

Stage 3: Severe 180mmHg systolic or 110 mmHg diastolic
What is an ABPM?
An ambulatory blood pressure monitor - small machine that regularly take BP - more accurate
