1 Cardiology Board Review – Part II March 21, 2013

2 A 65-year-old man is evaluated for 2 months of central chest pain with exertion and relief with rest, exertional dyspnea, orthopnea, and lower-extremity edema. He has a 25-year history of hypertension and a 44-year history of smoking. His only medication is hydrochlorothiazide. On physical examination, he is afebrile. Blood pressure is 118/80 mm Hg, pulse is 95/min, and respiration rate is 16/min. There is mild jugular venous distention. Cardiac examination reveals a regular rate and rhythm, normal S 1 and S 2, and no murmurs or S 3. Crackles are heard at both lung bases. There is mild bilateral edema at the ankles. Laboratory studies show a serum troponin T level of less than 0.01 ng/mL (0.01 µg/L). Electrocardiogram is normal. Echocardiogram shows an ejection fraction of 40%, global hypokinesis, and mild left ventricular hypertrophy Which of the following is the most appropriate diagnostic test? 1.Cardiac catheterization 2.Cardiac MRI 3.Radionuclide ventriculography 4.Nuclear medicine stress test 5.Standard exercise stress test

4 A 70-year-old woman is evaluated for a 1-month history of dyspnea on exertion and fatigue. She can still perform activities of daily living, including vacuuming, grocery shopping, and ascending two flights of stairs carrying laundry. She has a history of hypertension, mild COPD, and smoking. Her medications are lisinopril, hydrochlorothiazide, and albuterol as needed. On exam, she is afebrile. BP 110/80 mm Hg and HR 70/min. Jugular veins are not distended. There is a grade 2/6 holosystolic murmur at the left sternal border that radiates to the axilla, which was not noted during an examination 1 year ago. Rate and rhythm are regular, S 1 and S 2 are normal, and there is no S 3. The lung sounds are distant but clear without wheezing, and there is no edema. Laboratory studies show normal hemoglobin and TSH levels. Electrocardiogram shows low voltage and left axis deviation. Echocardiogram shows an ejection fraction of 35%, global hypokinesis, and mild mitral regurgitation. Chest radiograph shows flattening of the diaphragms but is otherwise normal Which of the following is the most appropriate treatment? 1.Amlodipine 2.Carvedilol 3.Digoxin 4.Losartan 5.Spironolactone

5 A 60-year-old white woman is evaluated for dyspnea with mild activity (ascending less than one flight of stairs, walking less than one block on level ground) that has been stable for the past year. She has a history of nonischemic cardiomyopathy (last ejection fraction 20%). Her current medications are lisinopril, carvedilol, digoxin, and furosemide. She had an implantable ICD placed 1 year ago. On physical examination, she is afebrile. Blood pressure is 95/75 mm Hg, and pulse rate is 70/min. Jugular veins are not distended, and the lungs are clear. Cardiac examination discloses a regular rate and rhythm, no murmurs, normal S 1 and S 2, and no S 3. There is no edema.

Which of the following is the most appropriate addition to her treatment 1.Angiotensin receptor blocker 2.Hydralazine 3.Metolazone 4.Spironolactone

6 A 65-year-old black man is evaluated during a routine annual visit. Over the past year he has had a progressive decline in functional status. Last year he could exercise by walking several blocks at a time, and now he gets tired after one block at most; sometimes he gets short of breath with dressing and showering. He reports no symptoms of orthopnea or paroxysmal nocturnal dyspnea and has had no change in medications since last year. He has a 25-year history of hypertension, a 5-year history of ischemic cardiomyopathy, and received an implantable ICD 1 year ago. An echocardiogram done 6 months ago showed an ejection fraction of 20%. He takes aspirin, enalapril, metoprolol, spironolactone, furosemide, digoxin, pravastatin, and isosorbide dinitrate. On physical examination, he is afebrile. Blood pressure is 100/70 mm Hg and pulse is 70/min. There is no jugular venous distention and the lungs are clear. Cardiac examination discloses a regular rate and rhythm with no S 3 or murmurs. There is no edema. Hgb and Creat are at his baseline. TFTs wnl, EKG shows NSR.

9 A 72-year-old man is evaluated for fatigue and dyspnea. Over the last several months to a year, he has had increasing fatigue, exercise intolerance, and dyspnea on even mild exertion. He becomes short of breath walking across a room, although he is asymptomatic at rest. He has a history of coronary artery disease, with a myocardial infarction and four-vessel coronary artery bypass graft surgery 4 years ago. He also has hyperlipidemia. Medications are aspirin, low-dose carvedilol, lisinopril, digoxin, spironolactone, furosemide, pravastatin. On exam, his BP is 92/57 mm Hg, HR 57/min, and RR 12/min. PMI is displaced laterally. Rhythm is regular and bradycardic. S 1 and S 2 are normal, with a grade 2/6 to 3/6 holosystolic murmur at the apex. An S 3 is present. Estimated CVP is 8 cm H 2 O; there is no hepatojugular reflux. The lungs are clear. There is no ascites. The liver edge is palpable 1 cm below the right costal margin. The lower extremities are warm with decreased distal pulses bilaterally. There is no ankle edema. ECG demonstrates sinus rhythm with a rate of 55/min. PR interval is 180 msec, QRS width is 180 msec, and QT interval is 380 msec. Left bundle branch block is seen. A dobutamine stress echocardiogram reveals a left ventricular ejection fraction of 33% with a large anteroapical area of akinesis and no ischemia. Which of the following is the most appropriate management option for this patient? 1.Add amiodarone 2.Biventricular pacemaker-defibrillator 3.Dual-chamber pacemaker 4.Implantable defibrillator

10 Device Therapy ICD – For prevention of primary sudden cardiac death if: Class II or III on optimal meds + Expected survival > 1 yr + EF <35% – For secondary prevention if: hx of significant vent arrhythmia or cardiac arrest BiV Pacemaker (Cardiac Resynchronization Therapy) – In CHF, interventricular conduction delay is common -> poor coordination of ventricular contraction -> poor hemodynamics – BiV device: one lead pacing RV, one lead in RA to sense intrinsic rhythm, one lead in coronary sinus to pace LV – Criteria: Class III or IV + EF 120ms, LBBB) – Benefit: increased QOL, increased exercise capacity, decreased symptoms, decreased mortality 22%

11 A 45-year-old man with NICM presents to the ED with progressive shortness of breath over one month and edema but no chest pain. Previously, he was symptomatic with moderate activity (New York Heart Association class II heart failure). He has a dual-chamber implantable ICD. Current medications are lisinopril, furosemide, and carvedilol; however, he ran out of carvedilol 6 weeks ago. His most recent echocardiogram 3 months ago showed an EF of 20%. On exam, he is afebrile, BP 80/50 mm Hg, HR 115/min, and RR 16/min. He has jugular venous distention. Heart rhythm is regular, and an S 3 is heard. Lung examination reveals crackles. Edema is present. The extremities are cool, and mentation is intact. Pertinent laboratory results include serum sodium, 130 meq/L, creatinine, 2.6 mg/dL (was normal 1 month ago), troponin <0.01 ng/mL. ECG shows no acute ischemic changes; QRS duration is 100 msec. Which of the following is the most appropriate treatment at this time? 1.Intravenous dobutamine 2.Intravenous furosemide 3.Intravenous nesiritide 4.Oral carvedilol

12 Cardiogenic Shock Causes: – Extensive MI (75%), myocarditis, end stage CM, prolonged bypass, etc Criteria: – Sustained hypotension + decreased CI (<2.2 L/min/m 2 ) + increased PCWP If evidence of inadequate perfusion, need INOTROPIC support – Dobutamine – inotrope with some vasodilation – Dopamine (low-med dose) 1-5µg/kg/min = increased renal blood flow and urine output (dopaminergic agonist properties) 5-15µg/kg/min = increased renal blood flow, increased HR, increased cardiac contractility/cardiac output (beta-agonist) >15µg/kg/min = vasoconstriction (alpha-agonist) – Milrinone – Phosphodiesterase inhibitor in cardiac and vascular tissue – vasodilation and inotropic effects watch for worsened hypotension; don’t use in renal failure If refractory to meds, consider Intraaortic Balloon Pump – Inflates during diastole to help with coronary perfusion – Deflates during systole to help decrease afterload If still refractory, consider LVAD or transplant

13 A 40-year-old man is admitted to the hospital after an episode of syncope at work. He has had a 1-week history of progressive shortness of breath, orthopnea, and fatigue. On admission he is found to be hypotensive and is started on intravenous dopamine. Echocardiogram shows dilated left and right ventricles with a left ventricular ejection fraction of 10% and no regional wall motion abnormalities. Telemetry shows frequent and prolonged runs of nonsustained ventricular tachycardia. He has no other medical problems and takes no medications. On physical examination, he is afebrile. Blood pressure is 70 mm Hg systolic, pulse is 110/min, and respiration rate is 20/min. The jugular veins are distended. Heart rate is regular, and a summation gallop is noted. There is no rash or skin lesions. Extremities are cool with no edema. Labs show a serum troponin level of 5 ng/mL. Chest radiograph shows mild cardiomegaly and pulmonary edema and no other abnormalities. Electrocardiogram shows sinus tachycardia, normal QRS duration, and frequent premature ventricular complexes. Cardiac catheterization after admission shows normal coronary arteries. Which of the following is the most appropriate management step? Biventricular pacemaker placement Cardiac MRI Endomyocardial biopsy Implantable defibrillator placement

15 A 77-year-old woman is admitted to the hospital for intermittent dizziness over the past few days. She does not have chest discomfort, dyspnea, palpitations, syncope, orthopnea, or edema. She underwent coronary artery bypass graft surgery 6 years ago after a myocardial infarction. She has hypertension, hyperlipidemia, and paroxysmal atrial fibrillation with a history of rapid ventricular response. She notes that over the past several years, she feels she has slowed down and has had problems with memory, which she attributes to aging. Medications are metoprolol, HCTZ, pravastatin, lisinopril, aspirin, and warfarin. On physical examination, her blood pressure is 137/88 mm Hg and her pulse is 52/min. Estimated central venous pressure is 7 cm H 2 O. The point of maximal impulse is felt in the fifth intercostal space and at the midcostal line. Cardiac auscultation reveals bradycardia with regular S 1 and S 2, as well as an S 4. A grade 2/6 early systolic murmur is heard at the left upper sternal border. The lungs are clear to auscultation. Edema is not present. On telemetry, she has sinus bradycardia with rates between 40/min and 50/min, with two symptomatic sinus pauses of 3 to 5 seconds each. Which of the following is the most appropriate management for this patient? 1.Add amiodarone 2.Discontinue metoprolol 3.Echocardiography 4.Pacemaker implantation

16 Bradycardia Don’t forget about Reversible Causes! – Lyme, hypothyroidism, hyperK, meds, ischemia Sick Sinus Syndrome/Sinus Node dysfunction – Typically seen in elderly – Associated with paroxysmal Afib/flutter in 50% – Tachy-brady syndrome = common subtype Tx: pacemaker + aggressive rate control AV Block – 1 st degree = prolonged PR due to delay within AV node – 2 nd degree Mobitz I (Wenckebach) = progressive delay of conduction within AV node, therefore progressive elongation of PR resulting in dropped beat Mobitz II = constant PR with intermittent failure of conduction – Needs pacemaker if advanced or symptomatic – 3 rd degree Escape rate: – Junctional (40-60 beats/min) – narrow QRS – Ventricular (slower) – wide QRS If reversible (Meds, Lyme, ischemia) – can monitor If nonreversible, need PACEMAKER

17 A 54-year-old man is evaluated for recurrent arrhythmia. He was diagnosed with atrial flutter with a rapid ventricular response 6 weeks ago. Rate control was initially difficult to achieve; he underwent cardioversion and was started on metoprolol. He has had general fatigue since initiation of metoprolol. Two days ago, he had a recurrence of his arrhythmia; his fatigue worsened, and he began experiencing dyspnea on exertion. He denies chest pain, lightheadedness, and heart racing. He has no other medical problems, and his only other medication is daily aspirin. On physical examination, his blood pressure is 123/65 mm Hg and his pulse is 50/min. BMI is 24. Cardiac examination reveals bradycardia with an irregular rhythm, normal S 1 and S 2, and no murmurs or gallops. Lungs are clear to auscultation. The electrocardiogram shows atrial flutter with a 6:1 block and a ventricular rate of 50/min. Which of the following is the most appropriate management for this patient? 1.Add amiodarone 2.Add digoxin 3.Discontinue metoprolol; initiate flecainide 4.Radiofrequency ablation

18 Tachycardia NarrowRegular Sinus Tach Atrial tach AVRTAVNRTIrregularFlutterAfibMATWide Pre- excitation (6%) SVT with aberrant conduction (20%) Vtach (80%) Treat as VT unless certain of other diagnosis If any of the above are unstable - need synchronized cardioversion If stable: vagal maneuver or adenosine (if AV node part of reentry circuit) ***Do NOT use AV nodal blockers if AVRT!!! After arrhythmia terminated, then check: EKG: looking for prior MI, LVH, long QT Echo: looking for underlying structural disease Labs: electrolytes, TFTs (K, Ca, Mg – disturbances may precipitate arrhythmias) AVNRT (60% of SVT) – reentry circuit within AV node AVRT (30% of SVT) – accessory pathway WPW

19 An 18-year-old woman is evaluated for recurrent syncope. She has experienced four syncopal episodes in her lifetime, all of which occurred during activity. The most recent was last week, when she dove into a pool and had a brief loss of consciousness. Episodes have no prodrome, and she has had no dizziness. She is healthy and active, without cardiopulmonary complaints, and takes no medications. Her maternal cousin drowned at age 10 years, and her mother has been diagnosed with a seizure disorder. On physical examination, her blood pressure is 112/65 mm Hg and her pulse is 67/min and regular. The cardiopulmonary and general physical examinations are normal. Which of the following is the most likely diagnosis? 1.Brugada syndrome 2.Long QT syndrome 3.Short QT syndrome 4.Wolff-Parkinson-White syndrome

20 A 67-year-old man presented to the emergency department 2 days ago with an acute ST- elevation myocardial infarction. During the initial evaluation, he became unresponsive due to ventricular fibrillation. He was successfully resuscitated and taken to the cardiac catheterization lab, where a 100% occlusion of his proximal left anterior descending artery was stented. His postinfarction course was notable for mild heart failure, which has now resolved. He is now stable on his current medical regimen. Current medications include aspirin, metoprolol, atorvastatin, clopidogrel, and lisinopril. On physical examination, his blood pressure is 115/72 mm Hg, his pulse is 65/min, and his respiration rate is 12/min. There is no jugular venous distention, crackles, murmur, or S 3. Transthoracic echocardiogram reveals mild hypokinesis of the anterior wall and a left ventricular ejection fraction of 42%. Which of the following is the best management option at this time? 1.Add amiodarone 2.Continue medical management 3.Implantable cardioverter-defibrillator placement 4.Order electrophysiology study

21 Tachycardia Pearls… Afib cardioversion for long-term control: – Without anticoagulation if Afib <48h – If >48h, need at least 3 weeks of therapeutic INR OR negative TEE while on heparin gtt *need 4 weeks anticoagulation after cardioversion WPW = AVRT *If Afib, use PROCAINAMIDE – No AV nodal blocking agents if Afib -> will go into Vfib!!! PVCs – treat only if symptomatic (AVN blockers) NSVT – (total duration <30s) – If symptomatic – use AVN blockers – Treat reversible ischemia if present – ICD if EF <35% (to protect from SVT) EP study if EF 35-55% -> if can induce SVT, then ICD needed SVT (>30s) – Commonly seen with prior MI – Amio or Lidocaine in acute setting (unless unstable – then cardioversion) – ICD if EF 35%; EP study if >35% for decision on ICD Sudden Cardiac Death – Vfib = most common cause Triggers: electrolyte disturbances, druge (cocaine, QT prolonging agents, etc), acute stress Genetics: familial dilated CM, HOCM, long QT syndrome, Brugada Syndrome

22 Which team has won the most NCAA Tournament Championships? 1.Kentucky 2.Duke 3.UNC 4.Indiana 5.UCLA 6.Michigan State 7.Kansas

He has had hypertension for 12 years. His medications are hydrochlorothiazide and amlodipine. On physical examination, temperature is 37.8 °C (100.0 °F), blood pressure is 168/100 mm Hg, pulse is 110/min, and respiration rate is 26/min. Oxygen saturation on ambient air is 96%. The patient’s face and chest appear diaphoretic. The oropharynx is erythematous. There is no jugular venous distention and no hepatojugular reflux. Cardiac examination discloses a two-component rub that is loudest at the apex, distant heart sounds, and no murmurs. Pulmonary examination discloses normal breath sounds and no crackles. Initial serum troponin T level is 0.6 ng/mL. ECG shows sinus tachycardia and concave upward ST-segment elevation in leads V 1 through V 6.

24 A 34-year-old woman is evaluated for sharp intermittent pleuritic chest pain that has persisted for 1 week. The pain is worse when she lies down in the supine position. She has had no fever, chills, cough, or weight loss. She had acute viral pericarditis 6 months ago that was treated initially with ibuprofen, but when she failed to respond after 3 days, a 10-day tapering dosage of prednisone was instituted, leading to resolution of clinical symptoms. Cardiac examination discloses a pericardial friction rub at the lower left sternal border but no gallops. ECG consistent with acute pericarditis. Which of the following is the most appropriate treatment? 1.Colchicine 2.High-dose ASA 3.High-dose Ibuprofen 4.Prednisone

25 Acute Pericarditis Acute Therapy – 1 st line: Anti-inflammatories (taper over 4-6 weeks) High dose ASA 650mg q4-6h – Preferred if pt post-MI Ibuprofen 800mg q8h – Not if renal failure – 2 nd line: Colchicine (add to 1 st line if persistent symptoms) Not if renal failure – 3 rd line: Prednisone 60mg/d – Avoid anticoagulation 10-30% will recur – Colchicine for recurrent disease

26 A 45-year-old man is evaluated in the emergency department for a 3-day history of progressively worsening dyspnea on exertion to the point that he is unable to walk more than one block without resting. He has had sharp intermittent pleuritic chest pain and a nonproductive cough with myalgias and malaise for 7 days and has had orthostatic dizziness for 2 days. He is taking no medications. On exam, temperature is 37.7 °C (99.9 °F), blood pressure is 88/44 mm Hg, pulse is 125/min, and respiration rate is 29/min. O2 Sat is 95%. Pulsus paradoxus is 15 mm Hg. Estimated CVP is 10 cm H 2 O.

40 PAD - Diagnosis ABIs (ankle pressure/brachial pressure) – – normal – – borderline – – mild-moderate PAD – – severe PAD – If >1.30 = noncompressible artery -> needs to try toe-brachial index Exercise ABIs – If normal ABIs but high suspicion for PAD – If ABI decrease by 20% post-exercise, then patient has significant PAD Segmental Limb Pressure recordings – To locate affected region MRA vs CTA – To locate affected region

41 A 68-year-old man is evaluated for left calf pain that occurs after walking 2 to 3 blocks and is relieved with rest; he has had the pain for about 6 months. He has a history of coronary artery disease with depressed left ventricular systolic function (left ventricular ejection fraction, 30%) treated with coronary artery bypass grafting 2 years ago and subsequent implanted cardiac defibrillator placement for primary prevention purposes. He has hypertension and hyperlipidemia, and is a prior cigarette smoker. His medications include atorvastatin, aspirin, metoprolol, and lisinopril. On physical examination, blood pressure is 110/70 mm Hg, pulse is 68/min and regular, and respiration rate is 16/min. Peripheral pulses are diminished. There is no skin breakdown or ulceration and no abdominal or femoral bruits. Ankle-brachial index is 0.7 on the left and 1.0 on the right. Segmental plethysmography demonstrates a pressure drop of 20 mm Hg below the left knee. Which of the following is the most appropriate treatment for this patient? 1.Femoral-popliteal bypass 2.Medical treatment with cilostazol 3.Percutaneous intervention 4.Supervised exercise program

42 PAD - Treatment If no lifestyle limiting symptoms: – RF modification (LDL <100, statin, stop smoking) – ASA, Bblocker – Exercise – Consider cilostasol if claudication (but not in CAD) If lifestyle limiting symptoms: – Angioplasty (best for short segments of large calibur vessels) – Bypass (best for distal, mutivessel occlusive disease)

44 A 72-year-old man is evaluated in the emergency department for acute severe pain during rest in the lower left leg that began 3 days ago. The patient has repeatedly used oxycodone/acetaminophen that he had at home for relief of pain. His pain is now much better, but he finds that he is having difficulty walking. He has had progressive exertional pain in the lower left leg over the past year. Five years ago, he had a left femoral popliteal bypass for occlusive peripheral arterial disease with distal ulceration. He has hypertension and hyperlipidemia. He has a 50 pack-year smoking history. Current daily medications include aspirin, lisinopril, hydrochlorothiazide, and simvastatin. On physical examination, the patient’s temperature is 37.8 °C (100.1 °F), blood pressure is 106/60 mm Hg, pulse is 100/min, and respiration rate is 20/min. The left lower extremity is pale and cool from the toes to the mid shin, and there is a small ulceration on the ball of the left foot. The left posterior tibialis and dorsalis pedis pulses are not palpable and cannot be identified by Doppler ultrasonography. Venous Doppler signals are audible. The left foot and calf feel stiff, and the patient can only weakly flex the foot. Toe movement on the left side is minimal, and sensation to light touch is absent. Which of the following is the most appropriate treatment for this patient? 1.Emergent surgical revascularization 2.Intravenous heparin 3.Intra-arterial thrombolytic therapy 4.Prompt amputation

45 Acute Limb Ischemia!! Remember the 6 P’s! Due to embolus or thrombosis = ACUTE SX Management: – Class I: mod-severe claudication but NO rest pain ASA, heparin, surgery consult – Class II: PAIN AT REST URGENT intervention; consider lytics – Class III: irreversible disease (absent dopplers, profound anesthesia, paralysis) Need amputation
