71
How should you monitor BP when starting / adjusting an anti-hypertensive medication?
BP should generally be monitored within 2-4 weeks of starting or adjusting antihypertensive medication
72
using ACEI's
- Good in co-morbid DM, coronary heart disease, chronic kidney disease, heart failure. - Usually well tolerated. - Check labs within 7-10 days. • Contraindicated in pregnancy.
73
using ARBs
- Good in co-morbid DM, coronary heart disease, chronic kidney disease, heart failure. - Usually well tolerated. - Check labs within 7-10 days. • Contraindicated in pregnancy.
74
using beta-blockers
- Good in patients with co-morbid heart failure, coronary heart disease/post-MI, migraines, tachycardias, essential tremor, portal hypertension, or thyrotoxicosis. - Unless a patient has one of these co-morbidities, β-blockers are not one of the first line agents - Do not abruptly stop - avoid in asthma unless cardioselective - use in caution with DM pts; can mask hypoglycemia symptoms - monitor heart rate and breathing
75
What are the cardioselective beta blockers?
- bisoprolol - atenolol - metoprolol - acebutalol - nebivolol
76
Which beta blockers have vasodilating activity?
- carvedilol - nebivolol - labetalol
77
Which beta blocker is renally and which is hepatically eliminated?
- renal: atenolol | - hepatic: metoprolol, carvedilol, propranolol
78
What is the most and least lipophillic beta blocker?
- most: propranolol - least: atenolol - highly lipophilic agents can cross the blood brain barrier better and may cause more CNS side effects
79
using thiazide diuretics
- more effective in lowering BP than loop diuretics - Diuretic effect goes away after about 1 week of consistent use - check labs within 7-10 days - Good in patients with co-morbid osteoporosis / osteopenia - Can precipitate gout - Chlorthalidone is about 1.5 – 2 times more potent for blood pressure lowering than hydrochlorothiazide; it is also more slightly potent at causing hypokalemia - Significant contraindication: with dofetilide (brand name, Tikosyn)
80
using loop diuretics
- Most effective for BP when used in patients with GFR < 30 mL/min. - Has a sulfonamide group, but is generally well tolerated among those patients with a reaction to sulfonamide drugs - Can precipitate gout
81
using Potassium-sparing diuretics
- Good choice for patients with “resistant” or “difficult to treat” hypertension - Excellent option for patient with known or suspected hyperaldosteronism - Must check labs within 3-7 days
82
using Non-dihydropyridine CCBs
- Contraindicated in patients with heart failure with a reduced ejection fraction - slow heart rate and weaken heart contractility - Good in patients with co-morbid tachycardias
83
using Dihydropyridine CCBs
- do not slow heart rate - peripheral edema is local - safe for all types of heart failures - Short-acting agents are no longer used as they are excessive at BP lowering
84
using α-1 Blockers
- Good in patients with co-morbid benign prostatic hypertrophy - Avoid as monotherapy - Dose at bedtime - should avoid this class in patients with an orthostatic pattern to their BP
85
Why should you avoid α-1 Blockers as monotherapy?
increase prevalence of development of heart failure
86
Why should you dose α-1 Blockers at bedtime?
to minimize risk of postural hypotension
87
using Central α-2 agonists
- avoid abrupt discontinuation - May need to use with diuretic to control fluid retention - Patch is generally better tolerated than tablet
88
using Direct Arterial Vasodilators
Generally used as one of the last additions
89
What are the Fab 4?
- Thiazide diuretics - ACEI - ARBs - Calcium channel blockers
90
What are the factors that contribute to high risk of CV event?
- Prior CV disease, stroke, or heart failure - Diabetes - Chronic Kidney Disease - Estimated 10-yr CV risk of 10% or higher based on ACC/AHA Risk estimator
91
How do you follow up on BP?
- Monthly for those not at their BP goal. | - Weekly for those with dangerously elevated BP (hypertensive crisis level).
92
treating Black patients

99
treating pts with HTN and heart failure
ACEI or ARB + BB + loop diuretic + AA regardless of BP. DHP CCB if needed for additional BP control.

112
What is the BP for hypertensive crisis and why?
- BP greater than 180/120 | - the risk of stroke at this level become exponentially higher
113
Chest pain could indicate which TOD?
Acute coronary syndrome (ex: myocardial infarction)
114
increased SOB could indicate which TOD?
Acute fluid retention in the lungs (which could be acute heart failure); could also indicate myocardial infarction
115
FAST symptoms could indicate which TOD?
- stroke - encephalopathy - intracranial hemorrhage
116
How do you manage hypertensive urgency?
- Optimize chronic therapy. - Avoid overly aggressive BP reduction (can cause hypotension-related problems). - Goal: reduce BP to Stage 1 level over period of several hours to several days - don't want to normalize BP too fast
117
How do you manage hypertensive emergency?
- Immediate BP reduction needed to limit progression of TOD. - Requires parenteral therapy. - Goal: reduce mean arterial BP (MAP) by no more than 25% within minutes to hours; NOT to obtain BP < 140/90
118
What are the parenteral agents used to treat hypertensive emergency?
- Clevidipine - fenoldopam - esmolol - enalaprilat - nitroprusside
119
How does the bladder affect BP?
- A full bladder can increase systolic BP around 20 – 30 mmHg - Have patient empty their bladder before checking their BP
