Test 4 HTN/HF/Angina Flashcards
A 55-year-old white man with seated office blood pressure (BP) readings of 138/89 mm Hg and 136/84 mm Hg is asked to return in 2 weeks for repeat measurements, which are 138/88 mm Hg and 134/82 mm Hg. Which of the following classifies his BP per the 2017 ACC/AHA guidelines?
A. Stage 2 hypertension
B. Stage 1 hypertension
C. Elevated BP
D. Optimal BP
Option B: Correct. The patient’s average BP falls within the range of systolic BP of 130–139 mm Hg or diastolic BP of 80–89 mm Hg, defined as stage 1 hypertension.
A 34-year-old black man presents to your clinic with a BP of 160/94 mm Hg. Repeat readings over the past 2 weeks average 156/92 mm Hg. The patient has no past medical history with the exception of Crohn disease, which is currently treated with chronic steroid therapy. He is also taking an over-the-counter NSAID for ongoing back pain. Physical examination and laboratory tests are unremarkable. Appropriate interventions at this time include:
A. No intervention because patient most likely has drug-induced hypertension
B. NSAID is appropriate as long as he follows the instructions on the package insert
C. Reassessment of the dose and need for long-term oral steroids
D. Initiation of antihypertensive therapy
Answer: C
Option A: Incorrect. Consistent elevations in BP require intervention with either treatment or evaluation of whether hypertension is secondary to alternative cause.
Option B: Incorrect. NSAID should be avoided as this can result in elevated BP and an increased risk of cardiovascular events.
Option C: Correct. It is reasonable to inquire for the need of long-term steroids and dose as this is a possible secondary cause for elevated blood pressures.
Option D: Incorrect. Prior to initiation of therapy, the secondary cause of hypertension should be ruled out or reassessed to see if treatment is necessary.
A 45-year-old African-American woman who has resistant hypertension, heart failure with reduced ejection fraction, type 2 diabetes, and dyslipidemia comes to the clinic for a medication management visit. Her current medications include enalapril/hydrochlorothiazide (Vaseretic), metoprolol succinate, hydralazine, isosorbide dinitrate, metformin, and atorvastatin. She has been adherent to all her medications. She complains of recently developed fatigue, arthralgia, and mild peripheral edema, and a butterfly rash across her nose and upper cheeks. Which of the following statements is correct?
A. The most likely medication causing this adverse reaction is the angiotensin-converting enzyme inhibitor, enalapril
B. This is likely to be a dose-independent adverse drug reaction
C. Testing for N-acetyltransferase-1 (NAT-1) and NAT-2 genes may help to prevent this adverse effect
D. Discontinue all medications due to unknown etiology of this reaction
Answer: C
Option A: Incorrect. Hydralazine is the most likely medication from her medication list to cause lupus-like syndrome.
Option B: Incorrect. Hydralazine induced lupus-like syndrome is a dose-dependent adverse reaction which may be avoided by using less than 200 mg daily.
Option C: Correct. FDA listed NAT-1 and NAT-2 genes as biomarkers for the effectiveness and or toxicity of hydralazine.
Option D: Incorrect. Hydralazine induced lupus-like is reversible on discontinuation. Therefore, discontinue hydralazine first and observe for days is recommended.
A 52-year-old Asian male is newly diagnosed with stage 1 hypertension. Significant lab values are potassium level of 4.5 mEq/L (mmol/L) and an estimated GFR of 25 mL/min/1.73 m2. His past medical history includes type 2 diabetes, chronic kidney disease (stage G4, A1), hyperlipidemia, and gout. His 10-year ASCVD risk is estimated at 10.8%. Which of the following medications would be preferred for this patient?
A. Chlorthalidone
B. Amlodipine
C. Losartan
D. Metoprolol tartrate
Answer: C
Option A: Incorrect. Thiazide-type diuretics, including chlorthalidone have negative metabolic effects like hyperglycemia, dyslipidemia, and hyperuricemia. Use with caution in patients with diabetes, hyperlipidemia, and gout. In addition, alternative agents are recommended in patients with estimated GFR less than 30 mL/min/1.73 m2.
Option B: Incorrect. Amlodipine can be considered a first-line agent in general. However, for patients with CKD, ACE-Is or ARBs should be initiated prior to other classes of antihypertensive agents.
Option C: Correct. ACE-Is or ARBs should be the first-line treatment for patients with CKD (stage 3 or higher or stage 1 or 2 with severely increased albuminuria) and without any contraindications (eg, history of angioedema or hypersensitivity with prior ACE-I or ARB use) regardless of age and race. These medications provide renal protective effects through reducing intraglomerular pressure.
Option D: Incorrect. Metoprolol is generally not considered as first-line treatment except for compelling indications such as post myocardial infarction or heart failure with reduced ejection fraction.
A 55-year-old black woman has a history of left ventricular hypertrophy with a left ventricular ejection fraction of 55% (0.55). She has had hypertension for 10 years and is currently taking chlorthalidone 25 mg daily, metoprolol succinate 50 mg daily, and amlodipine 2.5 mg daily. Her averaged BP is 152/94 mm Hg with a heart rate of 54 beats/min. Her physical examination is unremarkable and basic metabolic panel reveals serum creatinine of 0.8 mg/dL (71 µmol/L) and potassium of 3.9 mEq/L (mmol/L). She reports allergies to fosinopril and aspirin. Which of the following represents the optimal course of action?
A. Increase amlodipine to 5 mg and have her take it at bedtime
B. Increase metoprolol succinate to 100 mg daily
C. Add lisinopril 5 mg daily
D. Add spironolactone 50 mg daily
Answer: A
Option A: Correct. Amlodipine may be further titrated to a maximum dose of 10 mg daily to achieve BP control rather than adding new medications.
Option B: Incorrect. With an average heart rate of 54 beats/min, further titration of metoprolol succinate may result in bradycardia and result in patient harm.
Option C: Incorrect. The patient has an existing allergy to fosinopril. It would be best to avoid alternative ACE inhibitors.
Option D: Incorrect. It may be reasonable to add spironolactone if uncontrolled at future visits when current medications are titrated to optimal doses.
A 65-year-old black male presents to the clinic today with average BP of 148/88 mm Hg and heart rate of 70 beats/min. He has past medical history of type 2 diabetes and chronic obstructive pulmonary disease (group B). His most recent serum potassium is 3.6 mEq/L (mmol/L), serum creatinine is 0.9 mg/dL (80 µmol/L), calculated creatinine clearance is 92 mL/min (1.54 mL/s) and urine albumin is within normal limits. His current medication list includes atorvastatin, metformin, and inhaled tiotropium. Which of the following antihypertensives would be the most appropriate initial therapy?
A. Amlodipine
B. Chlorthalidone
C. Atenolol
D. Lisinopril
Answer: A
Option A: Correct. CCBs are appropriate as the initial therapy for this patient.
Option B: Incorrect. Thiazide-type diuretics can cause significant hypokalemia and this patient’s serum potassium is at the lower limit. In addition, the patient has type 2 diabetes and thiazide-type diuretics can have negative effect on glucose control.
Option C: Incorrect. β-Blockers are not first line medications for BP management without compelling indications. β-Blockers should also be avoided in patients with pulmonary diseases.
Option D: Incorrect. ACE inhibitors and ARBs should not be used as the first-line agent for African American patients with hypertension but no CKD due to their attenuated response in this population and higher risk for angioedema.
A 67-year-old Asian man with a recent non-ST segment elevation myocardial infarction (MI) (2 weeks ago) has an average BP of 138/86 mm Hg and a heart rate of 76 beats/min. Which of the following antihypertensive agents is preferred in this setting?
A. Metoprolol tartrate
B. Acebutolol
C. Hydrochlorothiazide
D. Spironolactone
Answer: A
Option A: Correct. Metoprolol tartrate and other β-blockers without intrinsic sympathomimetic activity are indicated in patients who are post-MI as a compelling indication for therapy.
Option B: Incorrect. Acebutolol despite being a β-blocker, also has intrinsic sympathomimetic activity and therefore would be cautioned in a patient with coronary artery disease.
Option C: Incorrect. Hydrochlorothiazide is a reasonable option if the patient did not have a compelling indication for alternative therapy.
Option D: Incorrect. Based on the information provided, spironolactone is not indicated at this time. It may be a reasonable option if the patient was later found to have a reduced left ventricular ejection fraction.
A 58-year old Indian American male presents to urgent care with chief complaints of severe headache, confusion, and blurred vision. Upon examination, his vital signs and relevant lab values include: BP 218/124 mm Hg; HR 92 beats/min; RR 18 breaths/min; serum potassium 4.8 mEq/L (mmol/L); serum creatinine 2.4 mg/dL (212 µmol/L); blood urea nitrogen 45 mg/dL (16.1 mmol/L); serum glucose 145 mg/dL (8.0 mmol/L); hemoglobin A1C 6.4% (0.064; 46 mmol/mol Hb); AST 28 U/L (0.47 µkat/L); ALT 20 U/L (0.33 µkat/L); urinalysis shows positive of proteins and negative of ketones. He has medical history of hypertension but no history of renal or hepatic impairment. According to the pharmacists, his antihypertensive medications are overdue for a refill by 2 months. Which of the following statements is most accurate?
A. He is experiencing hypertensive urgency
B. Goal is to reduce systolic blood pressure by up to 25% within an hour
C. Goal is to reduce systolic blood pressure by 25% to 50% within an hour
D. Administration of short-acting oral antihypertensive such as labetalol or clonidine is appropriate
Answer: B
Option A: Incorrect. He is experiencing hypertensive emergency because his BP is greater than 180/120 mm Hg with evidence of acute renal injury (elevated serum creatinine and protein in the urine)
Option B: Correct
Option C: Incorrect. Goal is to reduce systolic blood pressure by up to 25% within minutes to hours to prevent ischemic complications (decrease BP too rapidly) or further end organ damage (decrease BP too slowly).
Option D: Incorrect. Parenteral therapy such as nitroprusside or labetalol is required for hypertensive emergencies.
A 72-year-old black man with history of hypertension, prior MI, and benign prostatic hypertrophy, is currently receiving amlodipine 5 mg QAM and carvedilol 12.5 mg twice daily. He has an average 24-hour Ambulatory Blood Pressure of 156/92 mm Hg and HR of 60 beats/min with notable nocturnal hypertension. He complains of nocturia but states that the swelling in his feet improved when his amlodipine dose was reduced. Which of the following presents the most clinically appropriate course of action?
A. Increase amlodipine to 10 mg daily and change to bedtime
B. Increase carvedilol to 25 mg twice daily
C. Initiate chlorthalidone 50 mg daily in AM
D. Initiate lisinopril 5 mg once daily at bedtime
Answer: D
Option A: Incorrect. Patient reports an adverse event with higher doses of amlodipine, and it would be best to not titrate further.
Option B: Incorrect. With an average heart rate of 60 beats per minute, further titration of carvedilol may result in bradycardia and result in patient harm.
Option C: Incorrect. Chlorthalidone may worsen nocturia and does not have suggestion of compelling indication at this time. Also, this dose of chlorthalidone is high and would increase patient’s risk of metabolic and electrolyte adverse effects especially if initiated at this low dose.
Option D: Correct. Lisinopril administered in the evening is the best option due to the compelling indication of a prior MI and to attempt to control the patient’s nocturnal hypertension. Additionally, evening administration of at least one antihypertensive has been shown to reduce cardiovascular events.
A 57-year-old white woman has type 2 diabetes, morbid obesity, and hypertension. She is currently taking only lisinopril 20 mg daily and her office blood pressures are consistently at goal less than 130/80 mm Hg, but her home readings are significantly higher. Which of the following is a possible explanation for her elevated home readings?
A. Her home BP cuff is too small
B. She has white coat hypertension
C. Her home BP cuff is too large
D. She checks her blood pressure immediately after exercise
Answer: A
Option A: Correct. It is important to have the correct BP cuff size as cuffs that are too small will result in falsely elevated BP readings.
Option B: Incorrect. White coat hypertension would be suspected if results of office BP were routinely elevated but with normal home BP logs.
Option C: Incorrect. A BP cuff that is too large would likely provide falsely low measurement and would not explain the elevated home numbers.
Option D: Incorrect. It is unlikely that the patient is taking blood pressure readings directly following exercise and not the best answer.
A 72-year-old black man with history of heart failure with reduced left ventricular ejection fraction, dyslipidemia and peripheral arterial disease presents for risk factor reduction follow-up. His weight does not change from the baseline and he lacks any signs and symptoms for fluid retention. His blood pressure in clinic is 142/75 mm Hg initially and 140/77 mm Hg on repeat. Current medications include bisoprolol 10 mg once daily and valsartan 160 mg twice daily along with furosemide 20 mg as needed for edema. Current labs are stable and within normal limits with serum creatinine of 1.4 mg/dL (124 µmol/L) and potassium of 5.1 mEq/L (mmol/L). Which of the following additions to his medication regimen would be most appropriate at this time?
A. Amlodipine
B. Furosemide on regular daily basis
C. Hydralazine/Isosorbide dinitrate
D. Minoxidil
Answer: C
Option A: Incorrect. Amlodipine could be used in this patient but is not the best choice as dihydropyridine calcium channel blockers have not been tied to reduction in cardiovascular events in patients with HFrEF.
Option B: Incorrect. Furosemide and other loop diuretics are typically used for symptomatic benefit in heart failure patients and not primarily for blood pressure control.
Option C: Correct. The combination of nitrates and hydralazine is the best option due to a mortality benefit in black patients with symptomatic HFrEF.
Option D: Incorrect. Minoxidil is reserved for resistant hypertension refractory to most antihypertensive therapies and does not have an established role in heart failure patients and could potentially worsen edema.
A 63-year-old black man with a past medical history significant for hypertension and left ventricular hypertrophy is sent for 24-hour ambulatory blood pressure monitoring. Current medications include lisinopril 40 mg daily in AM, hydrochlorothiazide 12.5 mg daily in AM, and amlodipine 10 mg daily at bedtime. He is found to have controlled awake averages but his nocturnal values are elevated at 134/82 mm Hg. All laboratory results are within normal limits. Which of the following would be a reasonable change to his antihypertensive regimen?
A. Change amlodipine to nifedipine 30 mg twice daily
B. Replace hydrochlorothiazide with chlorthalidone 25 mg daily
C. Add spironolactone 50 mg daily
D. Add losartan 25 mg daily
Answer: B
Option A: Incorrect. Changing amlodipine to nifedipine would be unlikely to change overall blood pressure control at this point.
Option B: Correct. Switching hydrochlorothiazide to chlorthalidone would be reasonable to improve BP control especially nocturnal BP control given its longer effective half-life and data supporting a more consistent 24-hour BP lowering effect compared to hydrochlorothiazide.
Option C: Incorrect. Spironolactone administered daily is not the best option to address nocturnal hypertension.
Option D: Incorrect. Patient is already taking an ACE inhibitor.
A 54-year-old white man was brought to the emergency department an hour after ingesting 1500 mg lisinopril and 120 mg amlodipine. Initial vital signs showed significant hypotension of 72/36 mm Hg and tachycardia of 130 beats/min. Other physical examinations and laboratory tests were unremarkable. Toxicology screen was negative for alcohol, other usual licit and illicit substances. He has a history of hypertension and depression with poor adherence to medications. Which of the following statements is correct?
A. Supportive care such as fluid resuscitation and vasopressin administration should be considered only after the comprehensive toxicology report has returned to the medical team.
B. High dose insulin with glucose and calcium gluconate are appropriate treatments for this patient.
C. The consequences from antihypertensive agents overdose are usually mild; therefore, watchful waiting is an appropriate approach for this patient.
D. The toxicities of ACE-Is are generally more severe than CCBs.
Answer: B
Option A: Incorrect. Supportive care should be given to any symptomatic patients as soon as possible.
Option B: Correct. High dose insulin with glucose and calcium gluconate are appropriate treatments for CCB toxicity.
Option C: Incorrect. This patient was hemodynamically unstable, as noted by profound hypotension and tachycardia. Interventions should be taken immediately to maintain hemodynamic stability.
Option D: Incorrect. CCBs generally have more profound toxicities than ACE-Is.
A 32-year-old woman is 20 weeks pregnant and has a history of gestational diabetes. She presents with an average BP of 154/96 mm Hg and a heart rate of 60 beats/min. Her laboratory results are remarkable for proteinuria, elevated serum uric acid, and low potassium. Which of the following presents the most appropriate course of action?
A. Closely monitor her BP and provide supportive care
B. Start losartan 50 mg daily while monitoring BP
C. Start methyldopa 250 mg every 6 hours while monitoring BP
D. Start labetalol 100 mg every 12 hours while monitoring BP
Answer: C
Option A: Incorrect. Treatment is indicated.
Option B: Incorrect. Losartan and other angiotensin receptor blockers are contraindicated in pregnancy.
Option C: Correct. Methyldopa is a first-line agent in pregnancy and is the best answer choice.
Option D: Incorrect. With an average heart rate of 60 beats/min, initiation of labetalol may result in bradycardia and result in patient harm.
A 56-year-old black woman is currently on verapamil ER 360 mg once daily. She has a past medical history of hypertension and paroxysmal atrial fibrillation. Today, her office BP readings are 137/97 mm Hg and 144/96 mm Hg with a heart rate of 60 beats/min. Which of the following is the most appropriate intervention?
A. Add amlodipine 5 mg daily
B. Increase verapamil ER to 360 mg twice daily
C. Add chlorthalidone 12.5 mg daily
D. Add valsartan 80 mg daily
Answer: D
Option A: Incorrect. Patient is already receiving a calcium channel blocker in verapamil.
Option B: Incorrect. Verapamil ER 360 mg twice daily is above the usual dose and could result in bradycardia with current heart rate.
Option C: Incorrect. According to the 2017 ACC/AHA guidelines while thiazides are generally recommended in black adults for the treatment of hypertension, the recommendations for ARB therapy to prevent atrial fibrillation reoccurrence makes option D a better choice for this patient with paroxysmal atrial fibrillation.
Option D: Correct. ARBs are recommended by the ACC/AHA 2017 Hypertension Guideline to decrease atrial fibrillation reoccurrences.
Which of the following findings, when increased, indicates elevated cardiac filling pressures (or volume overload) in a patient with heart failure?
A. LVH
B. Potassium
C. LVEF
D. BNP
Answer: D
Option A: Incorrect. LVH is a marker of hypertrophy, but is not specific to volume status.
Option B: Incorrect. Potassium level is not indicative of volume.
Option C: Incorrect. LVEF provides information about the heart’s contractile function after completion of diastole.
Option D: Correct. B-type natriuretic peptide is released by the ventricles in response to chamber wall stretch and increased filling pressures that accompany volume retention.
What is the most common etiology of heart failure?
A. Ischemic
B. Idiopathic, unknown cause
C. Viral cardiomyopathy
D. Drug-induced
Answer: A
Option A: Correct. Ischemic etiology, resulting from coronary artery disease, is the most common cause of HFrEF, occurring in up to 2/3 of cases.
Option B: Incorrect. Idiopathic cardiomyopathy, while common, is not as frequent as ischemic etiology.
Options C and D: Incorrect. Viral and drug induced cardiomyopathy are rare causes of heart failure.
