Definition of hypertension „There is no dividing line. The relationship between arterial pressure and mortality is quantitative; the higher the pressure, the worse the prognosis.” (Pickering, 1972) The operational definition of hypertension is the level at which the benefit …of action exceed those of inaction.” (Rose, 1980) 4

Why is dangerous? Complications of hypertension –Cardiac (hypertrphy, failure, infarction) –Cerebral (ischemia, thrombosis, hemorrhage) –Renal (nephrosclerosis, failure) –Large vessel (aneurysm, dissection) –Atherosclerosis 9

Recommended Lifestyle Modifications and Their Individual Effects on Blood Pressure Chobanian AV, et al. JAMA. 2003;289: ; Blumenthal JA, et al. Arch Intern Med. 2000;160: Modifications*Recommendation Approximate SBP Reduction Reduce weight Maintain normal body weight (BMI of 18.524.9 kg/m 2 ) 320 mm Hg Adopt DASH diet Rich in fruit, vegetables, and low-fat dairy; reduced saturated and total fat content 814 mm Hg Reduce dietary sodium <100 mmol (2.4 g)/day 28 mm Hg Increase physical activity Aerobic activity >30 min/day most days of the week 49 mm Hg Moderate alcohol consumption Men: ≤ 2 drinks/day Women: ≤ 1 drink/day 24 mm Hg *Combining 2 or more of these modifications may or may not have an additive effect on blood pressure reduction. SBP = systolic blood pressure; BMI = body mass index; DASH = Dietary Approaches to Stop Hypertension

Initiation of antihypertensive treatment Journal of Hypertension 2007, 25:

Hypertension in emergency Hypertensive urgency BP > 230/130 mmHg without symptoms of target organ damage Hypertensive emergency BP elevation with serious target organ damage Eg. Encephalopathy, acute heart failure, acute coronaria sy, aortic dissection – acute BP lowering therapy needed 32

Therapy of hypertensive urgency and emergency Nitroglycerin (sublingual or iv.) ACEI (captopril, enalapril p.o.) Urapidil i.v. Short acting nifedipine (CI: angina, AMI) Labetalol Clonidin Sodium nitroprussid In special cases: loop diuretics 33
