According to 2017 hypertension guidelines from the American College of Cardiology and American Heart Association (ACC/AHA), Stage 2 high blood pressure (BP) is defined as 140 mm Hg or higher systolic or 90 mm Hg or higher diastolic.1 The risk for heart attack, stroke and other high blood pressure complications begins to increase around 115/75 mm Hg.1-5 The risk doubles for each 20 mm Hg increase in the systolic pressure and each 10 mm Hg increase in the diastolic pressure.1-5
Diagnosis of hypertension is based on an average of two or more careful blood pressure readings on two or more occasions when the patient is relaxed, sitting for more than five minutes, and has not done anything recently to increase BP such as smoke or exercise.1
Use of BP-lowering medications is recommended for people with Stage 2 hypertension.1 People started on medication should be reassessed in one month. 1
Evidence shows that lowering high BP decreases the risk of adverse cardiovascular outcomes such as heart disease, stroke, and death.6-9 It may also slow the progression of kidney damage in people with chronic kidney disease.10 Further, meta-analyses as well as national and international guidelines suggest that lowering BP decreases risk of these outcomes regardless of which agent is used. 6-9,6
