Total coronary blood flow is increased in severe AR
Ramipril
A 43 year old man complains of dyspnea on exertion and exertional chest pain. An echocardiographic demonstrates an aortic valve orifice area of less than 0.70 cm2, making it most appropriate to schedule the patient for which of the following?
Coronary angiography
A 45 year old woman with history of mitral valve prolapse presents with the acute onset of shortness of breath and fever. Physical examination reveals an early systolic murmur at the apex and bilateral pulmonary rales. Chest x-ray demonstrates bilateral pulmonary edema but not cardiomegaly. In addition to blood cultures, the next test that should be performed is which of the following?
Echocardiography
A 60-year-old man is hospitalized after he is taken to the emergency department because of dyspnea and leg edema. He has a longstanding history of essential hypertension that is treated with a thiazide diuretic and amlodipine. Coronary angiography performed 1 year ago because of chest pain was normal, but left ventriculogram showed an ejection fraction of 45%. On admission, blood pressure is 180/100 mm Hg and heart rate is 110/min and regular. Jugular venous distension
is 10 cm while the patient is lying on a stretcher with his head elevated at 45 degrees. He has a positive hepatojugular reflex, 2+ pitting leg edema to the knees, soft S1 and S2, an S3 gallop, and diffuse pulmonary crackles. No heart murmurs are auscultated. Echocardiogram shows left ventricular ejection fraction of 20% and left ventricular end-diastolic dimension in diastole of 7 cm. He has 1+ mitral and 1+ tricuspid regurgitation with an estimated right ventricular systolic pressure of 40 mm Hg. Electrocardiogram shows a left bundle branch block. Serum electrolytes and hepatic and renal function measurements are normal. Acute ischemic syndrome is excluded by repeated measurements of cardiac enzymes. He receives furosemide, three boluses of 60 mg intravenously, and nesiritide over a 24-hour period and improves rapidly with diuresis of 2200 mL. Which of the following drugs should be initiated before discharge to improve long-term survival in this patient?
Lisinopril
Which of the following statements regarding ACE inhibitors is true?
Captopril has been shown to reduce systemic arterial pressures and lower ventricular filling pressure
Captopril has been shown to reduce systemic arterial pressures and lower ventricular filling pressure
Clopidogrel, enoxaparin, tirofiban.
Which of the following is a feature of spironolactone?
It has been associated with reduced mortality in CHF, possibly by reducing arrhythmic death
Digoxin is of limited value for right sided heart failure
T
Which of the following statements regarding treatments for chronic stable angina is true?
A combination of β adrenergic blocking agents and nitrates is more effective than treatment with β adrenergic blocking agents alone
A 29-year-old woman in the 28th week of pregnancy has sudden onset of severe anterior chest pain radiating to her back. The pain began 2 hours earlier and increased in severity. It was not associated with shortness of breath, nausea or vomiting, or diaphoresis. The patient has a history of mitral valve prolapse that was diagnosed on echocardiogram 10 years earlier. Her only medication is a prenatal vitamin. Her family history is unremarkable. On physical examination, blood pressure is 105/78 mm Hg, heart rate is 110/min, and respiration rate is 18/min while the patient is lying still. The patient is afebrile. Examination of the head, eyes, ears, nose, and throat shows a high, arched palate. Carotid pulses are normal bilaterally, with no jugular venous distension. The lungs are clear to auscultation. Cardiac examination shows a nondisplaced apical impulse, diminished S1, physiologically split , and a soft blowing murmur in early diastole along the right sternal border. A midsystolic click and a late systolic murmur are noted. Abdominal examination shows a gravid uterus that is appropriate for gestational age. Trace pedal edema and intact symmetrical pulses are noted throughout. Fetal heart sounds are normal. An electrocardiogram shows mild T-wave flattening. Laboratory
findings include hematocrit of 32% and platelet count of 170,000/μL. Fetal monitoring is instituted, and morphine is administered for pain control. Which of the following is the most appropriate diagnostic test?
Transesophageal echocardiography
A 25-year-old pregnant woman is referred to you for evaluation of a heart murmur that was noted during the second trimester of this pregnancy, which is her first. The patient has no history of cardiovascular disease, and the murmur was not heard during previous medical evaluations. She is asymptomatic. Examination shows a mildly displaced apical impulse and lower extremity edema. S1 and S2 are normal, and S3 is noted at the apex. A grade 2/6 early to mid-peaking systolic murmur is audible at the left sternal border. Based on the patients history and physical findings, which of the following is the most likely cause of the murmur?
Physiologic murmur related to pregnancy
For which of the following patients should primary PCI be considered over thrombolytic therapy?
A 58 yar old with blood pressure on presentation of 190/ 110 mmHg
A 47-year-old woman is evaluated for palpitations that occur intermittently during the day, vary in severity, and cause a sensation of skipped beats. She has no other associated symptoms. She had a similar episode 2 years ago while undergoing a stressful job relocation, but did not seek medical attention at that time. She is now under pressure at work, and her son is leaving for college in 1 week. On physical examination, her blood pressure is 160/90 mm Hg and her heart rate is 80/min. Cardiac examination shows normal heart sounds and no murmurs. Electrocardiogram shows sinus rhythm with premature atrial contractions, and a 24-hour ambulatory monitor shows 5673 premature atrial contractions, 127 premature ventricular contractions, and no runs of arrhythmias. Results of laboratory tests, including thyroid function tests and complete blood count, are normal. The patient remains highly symptomatic, despite reassurance.
Which of the following is the most appropriate next step in the management of this patient?
Start β-blocker therapy
Vasodilators are useful in the management of patient with acute AR
T
Total coronary blood flow is increased in severe AR
T
Which of the following statements regarding the management of patients with chronic aortic regurgitation is true?
Vasodilators are of short term benefit in patients in functional classes III and IV heart failure
Diuretic therapy is recommended for every patient with acute and chronic heart failure with signs and/or symptoms of fluid overload. This recommendation is based on :
Diuretic’s rapid induction of diuresis and reduction of fluid and sodium overload
â blocker therapy is recommended for all patients with stable heart failure and reduced ejection fraction, unless there is a specific contraindication, or a specific patient is unable to tolerate treatment. Therapy should be commenced upon diagnosis. However only certain â blockers are recommended by guidelines for managing heart failure. Which of the following is not a guideline-recommended â blocker for heart failure?
Immediate –release metoprolol (tartrate)
Successful beta blocker therapy is dependent on correct dosing. The recommended dosing strategy for beta blocker therapy is :
Up[titration (as tolerated) until the dosages shown effective in clinical trials are achieved
