ABFM HYPERTENSION QUESTIONS AND ANSWERSA 39-year-old male sees you for evaluation of high blood pressure. His past medical
history is unremarkable. On examination he has a BMI of 32 kg/m2 and you note that he
has a round face and a plethoric complexion. His blood pressure is 150/98 mm Hg, his
pulse rate is 88 beats/min, and his respiratory rate is 16/min. Other notable findings
include a prominent dorsal cervical fat pad and supraclavicular fat pads, as well as
violaceous striae on his trunk. Laboratory findings are notable only for a fasting glucose
level of 114 mg/dL.Which one of the following is the most likely cause of his
hypertension?
Addison's disease
Cushing syndrome
Hemochromatosis
Pheochromocytoma
Primary hyperaldosteronism - Answers-B
This patient's clinical findings are consistent with Cushing syndrome, or
hyperadrenocorticism. This is a clinical syndrome and metabolic disorder resulting from
chronic excess of glucocorticoids. The most common cause is corticosteroid use, but
adrenal neoplasms account for 20%-25% of cases. Findings include general weakness,
osteoporosis, moon facies, facial plethora, ecchymoses, truncal obesity, violaceous
striae of the abdomen, deposition of adipose tissue in the interscapular area ("buffalo
hump"), and glucose intolerance.
You diagnose stage 2 hypertension in a 54-year-old male. His past medical history is
otherwise unremarkable and a physical examination is notable for mild AV nicking on
funduscopic examination. A baseline EKG reveals evidence of left ventricular
hypertrophy.Which one of the following classes of antihypertensive agents has NOT
been shown to produce a regression of left ventricular hypertrophy?
ACE inhibitors
β-Blockers
Calcium channel blockers
Direct vasodilators
Thiazide diuretics - Answers-D
The ALTITUDE study (Aliskiren Trial in Type 2 Diabetes Using Cardiorenal Endpoints)
was a randomized, double-blind, placebo-controlled international multicenter trial
undertaken to determine whether the addition of the direct renin inhibitor aliskiren to
standard therapy with renin-angiotensin system blockade would be beneficial for
patients with type 2 diabetes who are at high risk for cardiovascular and renal events.
The study was terminated prematurely after a median follow-up of 27 months when no
benefit was apparent, and a higher risk of hyperkalemia and hypotension was seen in
patients receiving aliskiren. Based on this study, the FDA issued a drug safety warning
in 2012 that announced two additions to the drug labeling of aliskiren-containing
products. The first addition was a contraindication to the use of aliskiren in patients with
diabetes mellitus who are taking angiotensin receptor blockers (ARBs) or ACE
,inhibitors, because of an increased risk of renal impairment, hypotension, and
hyperkalemia. The second addition was a warning to avoid the use of aliskiren with
ARBs or ACE inhibitors in patients with moderate to severe renal impairment
(glomerular filtration rate <60 mL/min/1.73 m2).The use of ACE inhibitors, ARBs, β-
blockers, diuretics, and calcium channel blockers has been shown to be effective in
reducing cardiovascular events in patients with diabetes mellitus. Although no such
benefit has been seen with doxazosin, there is no contraindication to its use in patients
with diabetes.
A 44-year-old male has a 1-week history of generalized headaches and nonspecific
dizziness. His past medical history is notable only for a 3-year history of hypertension,
which has been poorly controlled because of a lack of adherence to his drug regimen.
His renal status was normal 1 month ago. On examination his blood pressure is
250/150 mm Hg, and you note cotton-wool exudates on funduscopic examination.
Laboratory evaluation reveals normal serum electrolytes, a serum creatinine level of 3.8
mg/dL (N 0.7-1.3), and a BUN level of 60 mg/dL (N 6-20). A urinalysis shows gross
hematuria and 3+ proteinuria.Which one of the following will rapidly lower his blood
pressure and increase renal blood flow?
Diazoxide (Proglycem)
Enalaprilat (Vasotec)
Esmolol (Brevibloc)
Fenoldopam (Corlopam)
Nitroprusside (Nitropress) - Answers-D
Fenoldopam is a selective peripheral dopamine-receptor agonist used for the treatment
of severe hypertension. In studies investigating fenoldopam use in severe hypertension,
its efficacy in lowering blood pressure was found to be comparable to that of
nitroprusside. It is FDA-approved for the in-hospital management of severe
hypertension when rapid but quickly reversible reduction of blood pressure is required,
such as in a patient with malignant hypertension who has deteriorating end-organ
function. By virtue of its actions on peripheral dopamine receptors, fenoldopam
produces renal arterial vasodilation and natriuresis, and thus can provide a renal
protective effect in clinical situations associated with impaired renal function. In addition,
there is evidence that it may improve creatinine clearance and urine flow rates in
severely hypertensive patients with either normal or impaired renal function. The 2017
American College of Cardiology/American Heart Association (ACC/AHA) hypertension
guidelines include fenoldopam as a preferred agent for treating hypertensive
emergencies associated with acute renal failure. Other options include nicardipine and
clevidipine.
Compared to the typical American diet, the Dietary Approaches to Stop Hypertension
(DASH) diet includes reduced consumption of which one of the following?
Dietary fiber
Dietary protein
Low-fat dairy products
Nuts and whole grains
,Fats and sweets - Answers-E
Compared to a control diet with a high sodium level, the low-sodium Dietary Approaches
to Stop Hypertension (DASH) diet was found to lower mean systolic blood pressure 7.1
mm Hg in participants without hypertension and 11.5 mm Hg in participants with
hypertension. The DASH diet emphasizes fruits, vegetables, and low-fat dairy foods,
and includes whole grains, poultry, fish, and nuts, and contains smaller amounts of red
meats, sweets, and sugar-containing beverages than the typical American diet. It also
provides smaller amounts of cholesterol and total and saturated fat, and larger amounts
of potassium, dietary fiber, and protein.
An obese 64-year-old female with a history of hypercholesterolemia has a blood
pressure of 168/102 mm Hg and is started on hydrochlorothiazide and amlodipine
(Norvasc). For patients such as this, the 2017 treatment guidelines jointly developed by
the American Academy of Family Physicians and the American College of Physicians
recommend a target systolic blood pressure of less than
160 mm Hg
150 mm Hg
140 mm Hg
135 mm Hg
130 mm Hg - Answers-B
The target blood pressure for older patients continues to be an area of controversy,
particularly as it relates to systolic blood pressure (SBP). Although a target blood
pressure of <140/90 mm Hg was generally favored in the past, the JNC 8 panel found
insufficient evidence to conclude that a goal SBP of <140 mm Hg in patients age 60 or
over provided additional benefit compared with a goal SBP of <140-160 mm Hg or
<140-149 mm Hg. Accordingly, the JNC 8 panel recommends a goal SBP of <150 mm
Hg and a goal diastolic blood pressure of <90 mm Hg in those age 60 or over (SOR A).
The higher target blood pressure recommended by the JNC 8 panel has generated
controversy, as reflected in a special article published in the Annals of Internal Medicine,
written by five members of the original 18-member JNC 8 panel who disagreed with
lowering the target blood pressure in subjects older than 60.Support for lowering the
target blood pressure can be found in the Systolic Blood Pressure Intervention Trial
(SPRINT) findings, which were published after the JNC 8 panel recommendations and
reported a significant reduction in major cardiovascular events among hypertensive
patients over age 50 at high cardiovascular risk if a target SBP of <120 mm Hg was
used, when compared to a target of <140 mm Hg. Although the 2017 American College
of Cardiology/American Heart Association (ACC/AHA) hypertension guidelines generally
support a target blood pressure of <130/80 mm Hg in ambulatory community-dwelling
adults over 65 years of age, they also urge caution in older adults with a high burden of
comorbidity and a limited life expectancy. Earlier the same year, the American College
of Physicians (ACP) and the American Academy of Family Physicians (AAFP) jointly
issued a joint clinical practice guideline that was in general agreement with JNC 8, fav
, In patients with left ventricular hypertrophy, studies have shown a reduction in left
ventricular mass in those treated with ACE inhibitors, diuretics, calcium channel
blockers, and β-blockers, with the most consistent reduction achieved with ACE
inhibitors and the least with β-blockers. Regression of left ventricular hypertrophy has
not been demonstrated with direct vasodilators such as hydralazine and minoxidil.
According to currently accepted criteria, hypertension in children is defined as repeated
blood pressure measurements at or above a threshold of which one of the following
percentiles for age, sex, and height?
80th
85th
90th
95th
99th - Answers-D
In children and adolescents, hypertension is defined as blood pressure at or above the
95th percentile for age, sex, and height, on repeated measurements.
Which one of the following conditions is associated with isolated systolic hypertension?
Aortic stenosis
Hypothyroidism
Paget's disease
Renovascular hypertension
Severe osteoporosis - Answers-C
Isolated elevation of systolic blood pressure can be secondary to conditions associated
with elevated cardiac output, such as anemia, Paget's disease, hyperthyroidism,
arteriovenous fistula, and aortic insufficiency.
