Diagnosis algorithm. This algorithm does not apply to very elderly patients (age ≥80 years) because their treatment threshold and targets are 150/90 mmHg. For special patient groups (coronary heart disease, diabetes, or proteinuric chronic kidney disease), lower BPs are applied (* ≥130/80 mmHg; # 120–129/70–79 mmHg; § <120/70 mmHg). ABPM = ambulatory blood pressure monitoring; BP = blood pressure; FU = follow-up; HBPM = home blood pressure monitoring; LSM = life style modification; m = month; TOD = target organ damage (including left ventricular hypertrophy by electrocardiogram, microalbuminuria, or asymptomatic atherosclerosis [carotid intima-media thickening or aortic plaque], ankle-brachial index<0.9, or increased pulse wave velocity); y = year.

Rule of 10. Panel A. Comparison of effects of incremental doses of 5 classes of anti-hypertension drugs on reducing systolic blood pressure (SBP) at a baseline SBP of 154 mmHg. On average, there is a 10-mmHg decrease in SBP by a standard dose of any kind of the 5 classes of drugs (Rule of 10). Doubling the dose of any drug brings out only a 2-mmHg incremental decrease in SBP. Panel B. Combination of drugs from different classes is more effective in reducing SBP than increasing doses of the same drug. The combination of 2 drugs from different classes decreases SBP by 20 mmHg (10 + 10 = 20); whereas doubling doses decreased SBP further by 2 mmHg only (10 + 2 = 12). To decrease SBP by 30 mmHg, 3 drugs of different classes are generally needed. Data were modified from article by Laws et al.245

Rule of 5. Panel A. Comparison of the effects of incremental doses of 5 classes of anti-hypertension drugs on reducing diastolic blood pressure (DBP) at a baseline DBP of 97 mmHg. On average, there is a 5-mmHg decrease in DBP by a standard dose of any kind of the 5 classes of drugs (Rule of 5). Doubling the dose of any drug brings out only a 1-mmHg incremental decrease in DBP. Panel B. Combination of drugs from different classes is more effective in reducing DBP than increasing doses of the same drug. The combination of 2 drugs from different classes decreases DBP by 10 mmHg (5 + 5 = 10); whereas doubling doses decreased DBP further by 1 mmHg only (5 + 1 = 6). To decrease DBP by 15 mmHg, 3 drugs of different classes are generally needed. Data were modified from article by Laws et al.245
