1 혈압의효과적인 조절방법 ( 저항성고혈압과임 신성고혈압중심으로 ) 대한고혈압학회진료지침을중심으로 - (2016 년 2 월개정교육표준슬라이드 ) 연세의대내과학교실심장내과박성하

2 Initiation of antihypertensive drug treatment

3 고혈압약선택의원칙 (1) 약을처음투여할때는부작용을피하기위해저용량으로시작함. 약효가 24시간지속되어 1일 1회복용이가능한약을선택함. 최저 / 최대효과 (trough/peak ratio) 0.5 1일 1회투여로부족하면 2회이상나누어투여함. 일차고혈압약으로 ACE 억제제, 안지오텐신수용체차단제 (ARB), 베타차단제, 칼슘차단제, 이뇨제중에서선택하며적응증, 금기사항, 환자의동반질환, 무증상장기손상등을고려함.

4 고혈압약선택의원칙 (2) 동반질환에대한효과를우선적으로고려함. 노인에서베타차단제는치료이득에대한논란이있음. 베타차단제와이뇨제의병용투여는당뇨병발생의위험이높은환자에게는주의가필요함. 혈압이 160/100 mmhg 이상이거나, 목표혈압보다 20/10 mmhg 이상높은경우는처음부터병용투여가가능함. 병용요법은강압효과를상승시키고부작용을줄이고, 환자의약순응도를증가시켜, 심혈관질환과무증상장기손상을방지하는데도움이됨.

18 Follow-up of hypertensive patients: ESH/ESC After initiating anti-ht drug therapy, it is important to see the patient at 2- to 4-week intervals to evaluate the effects on BP and the possible side effects. Once the target is reached, a visit interval between 3- and 6- month is evidenced to be not different. It is nevertheless advisable to assess risk factors and asymptomatic OD at least every 2 years. Subjects with high normal BP or white-coat HT without medication should be regularly follow-up (at least annually) to measure office and out-of-office BP as well as CV risk profile.

19 Hypertensive emergency Large elevations in BP > 180/120mmHg with impending or progressive organ damage Large elevation in BP > 180/120mmHg without organ damage urgent HT HT emergencies 25% reduction within the first few hours 2013 ESH/ESC guidelines J Hypertens 2013;31:

47 Categories Chronic Hypertension Gestational Hypertension Preeclampsia Preeclampsia superimposed on Chronic Hypertension

48 Chronic Hypertension Preexisting Hypertension Definition Systolic pressure 140 mmhg, diastolic pressure 90 mmhg, or both. Presents before 20 th week of pregnancy or persists longer then 12 weeks postpartum. Causes Primary = Essential Hypertension Secondary = Result of other medical condition (ie: renal disease)

49 Prenatal Care for Chronic Hypertensives Electrocardiogram should be obtained in women with long-standing hypertension. Baseline laboratory tests Urinalysis, urine culture, and serum creatinine, glucose, and electrolytes Tests will rule out renal disease, and identify comorbidities such as diabetes mellitus. Women with proteinuria on a urine dipstick should have a quantitative test for urine protein. 2ndary HT should be ruled out

50 Treatment for Chronic Hypertension 1. Avoid treatment in women with uncomplicated mild essential HTN as blood pressure may decrease in the 1 st and 2 nd trimester 2. May taper or discontinue meds for women with blood pressures less than 150/95mmHg in 1 st and 2 nd trimester. 3. Reinstitute or initiate therapy for persistent diastolic pressures >95 mmhg, systolic pressures >150 mmhg 4. Start therapy > 140/90mmHg with gestational HT, organ damage, symptoms, preeclampsia To prevent stroke 5. Medication choices = Oral methyldopa, labetalol, nifedipine(iia), 2 nd line: oral hydralazine 6. Target SBP; mmHg

51 Preeclampsia superimposed on Chronic Hypertension Affects 10-25% of patients with chronic HTN Preexisting Hypertension with the following additional signs/symptoms: New onset proteinuria Hypertension and proteinuria beginning prior to 20 weeks of gestation. A sudden increase in blood pressure. Thrombocytopenia. Elevated aminotransferases.

52 Treatment of Preeclampsia Definitive Treatment = Delivery Major indication for antihypertensive therapy is prevention of stroke. Diastolic pressure 90 mmhg or systolic pressure 140 mmhg Choice of drug therapy: Acute IV labetalol, IV hydralazine, SR Nifedipine Long-term Oral methyldopa, labetalol, nifedipine

53 Gestational Hypertension Mild hypertension without proteinuria or other signs of preeclampsia. Develops in late pregnancy, after 20 weeks gestation. Resolves by 12 weeks postpartum. Can progress onto preeclampsia. Often when hypertension develops <30 weeks gestation. Indications for and choice of antihypertensive therapy are the same as for women with preeclampsia Diastolic pressure 90 mmhg or systolic pressure 140 mmhg
