Document Summary
Should be done on at least 3 separate occasions: 3 sets of 3 readings interval of > 2 weeks, unless the initial levels is >120 mmhg or target organ damage is present. Pt should sit or lie down quietly for > 5 mins before. Avoid smoking or eating within 30 mins before. Automated bp machines are better because: reduces the white coat response, quality and accuracy of automated is better. Hypertension: search for exogenous, potentially modifiable factors that can induce/aggravate htn. Excessive alcohol use: routine lab tests, urinalysis, blood chemistry (potassium, sodium, creatinine) Serum total cholesterol, ldl, hdl, non-hdl, tg may be drawn fasting or non-fasting. Standard 12-lead electrocardiography: risk assessment using some sort of cvd calculator. Reduce sodium intake to 2000 mg (5 g salt, or 87 mmol sodium) per day to reduce bp. Health canada: aim for 1500 mg/day, don"t go over. 2300 mg/day: average canadian intake = ~3000 mg/day.
