2017 ACC/AHA Practice Guideline for the Management of Hypertension Common CVD Risk Factors in Patients With Hypertension Modifiable Relatively Fixed Current cigarette smoking, secondhand smoking CKD Diabetes mellitus Family history Dyslipidemia/hypercholesterolemia Increased age Overweight/obesity Low socioeconomic/educational status Physical inactivity/low fitness Male sex Unhealthy diet Obstructive sleep apnea Psychosocial stress Adult patients with hypertension have other CVD risk factors Higher percentage of adults with CVD risk factors have hypertension (i.e. 71% of US adults with diagnosed DM have hypertension) CVD risk factors affect BP through over activation of the renin-angiotensin-aldosterone system, activation of the sympathetic nervous system, inhibition of the cardiac natriuretic peptide system, endothelial dysfunction, and other mechanisms o Treating some of the other modifiable risk factors may reduce BP through modification of shared pathology Causes of Secondary Hypertension Sleep apnea Renal disease/CKD Primary aldosteronism Drug/alcohol-induced Cushing’s syndrome Pheochromocytoma Thyroid dysfunction Aortic Coarctation Alcohol Amphetamines MAOI, SNRI, TCA Atypical antipsychotics (clozapine, olanzapine) Caffeine Decongestants (phenylephrine, pseudoephedrine) Immunosuppressants (cyclosporine) Oral contraceptives NSAIDs Recreational drugs (bath salts, cocaine, meth) Systemic corticosteroids Drug Induced HTN 1/day F and 2/d M D/C or decrease dose Consider SSRI, avoid tyramine with MAOI D/C or limit use, consider alt agents with lower weight gain/DM/dyslipidemia (ziprasidone, aripiprazole) Limit to <300 mg/d Use for shorted duration possible, consider alt. therapies Consider converting to tacrolimus Use low dose (20-30 mg ethinyl estradiol) or progestin-only, consider alternative forms of birth control (IUD) Avoid systemic NSAIDs, consider alternative analgesics D/C Avoid or limit use, consider alternate routes of administration when possible 1 2017 ACC/AHA Practice Guideline for the Management of Hypertension Step 1: Properly prepare the patient Step 2: Use proper technique for BP measurements Step 3: Take the proper measurements needed for diagnosis and treatment of elevated BP/hypertension Step 4: Properly document accurate BP readings Step 5: Average the readings Step 6: Provide BP readings to patient Accurate Blood Pressure Measurement 1. Have the patient relax, sitting in a chair (feet on floor, back supported) for >5 min. 2. The patient should avoid caffeine, exercise, and smoking for at least 30 min before measurement. 3. Ensure patient has emptied his/her bladder. 4. Neither the patient nor the observer should talk during the rest period or during the measurement. 5. Remove all clothing covering the location of cuff placement. 6. Measurements made while the patient is sitting or lying on an examining table do not fulfill these criteria. 1. Use a BP measurement device that has been validated, and ensure that the device is calibrated periodically. 2. Support the patient’s arm (eg, resting on a desk). 3. Position the middle of the cuff on the patient’s upper arm at the level of the right atrium (the midpoint of the sternum). 4. Use the correct cuff size, such that the bladder encircles 80% of the arm, and note if a larger- or smaller-than-normal cuff size is used. 5. Either the stethoscope diaphragm or bell may be used for auscultatory readings. 1. At the first visit, record BP in both arms. Use the arm that gives the higher reading for subsequent readings. 2. Separate repeated measurements by 1–2 min. 3. For auscultatory determinations, use a palpated estimate of radial pulse obliteration pressure to estimate SBP. Inflate the cuff 20–30 mm Hg above this level for an auscultatory determination of the BP level. 4. For auscultatory readings, deflate the cuff pressure 2 mm Hg per second, and listen for Korotkoff sounds. 1. Record SBP and DBP. If using the auscultatory technique, record SBP and DBP as onset of the first Korotkoff sound and disappearance of all Korotkoff sounds, respectively, using the nearest even number. 2. Note the time of most recent BP medication taken before measurements. Use an average of ≥2 readings obtained on ≥2 occasions to estimate the individual’s level of BP. Provide patients the SBP/DBP readings both verbally and in writing. Out-of-Office Blood Pressure Measurements Recommended to confirm HTN diagnosis and to titrate medications Training should occur for home blood pressure monitoring(HBPM) o Automated devices, appropriate cuff size o Remain still, avoid smoking, caffeine, exercise for 30m prior; feet on the floor; keep arm supported on flat surface 2 2017 ACC/AHA Practice Guideline for the Management of Hypertension o Take at least 2 readings 1 min apart before taking medications and in the evening before dinner o Optimally measure daily o Record all readings Ambulatory blood pressure monitoring (ABPM) is preferred method for out-of-office measurements o Monitors usually programmed to obtain readings every 15-30m during the day and every 15m-1h during the night o Can determine the nocturnal “dipping” of blood pressure and daily/nighttime patterns o Machine may be reimbursable to patients with suspected white-coat HTN and masked HTN White-coat HTN - office BP elevated (>130/80 and <160/100) but daytime ABPM or HBPM is not Masked HTN – office BP 120-129/<80 but ABPM or HBPM >130/80 Clinic 120/80 130/80 140/90 160/100 Corresponding SBP/DBP Values for Measurement Kinds HBPM Daytime ABPM Nighttime ABPM 120/80 120/80 100/65 130/80 130/80 110/65 135/85 135/85 120/70 145/90 145/90 140/85 Category Normal Elevated Hypertension Stage 1 Stage 2 Hypertensive Crisis Hypertensive Emergency Population Uncomplicated HTN Diabetes CKD Older Adults Blood Pressure Classification SBP (mmHg) < 120 And 120 – 129 And 24-hour ABPM 115/75 125/75 130/80 145/90 DBP (mmHg) < 80 < 80 130 – 139 Or 80 – 89 ≥ 140 Or ≥ 90 > 180 And/or > 120 Hypertensive crisis + evidence of acute target organ damage Blood Pressure Goals Across Guidelines ACC/AHA Other Guideline Recommendations < 130 / 80 < 130 / 80 ADA 2023 < 130 / 80 < 130 / 80 KDIGO 2021 < 120 SBP < 130 SBP ACP/AAFP 2017 General: < 150 SBP Stroke/TIA or high CV risk: < 140 SBP 3 2017 ACC/AHA Practice Guideline for the Management of Hypertension Non-Pharmacologic Treatment Treatment Weight loss DASH diet Dietary Sodium Dietary Potassium Aerobic exercise Dynamic resistance exercise Alcohol Intervention Goal: IBW;
