Cardio Flashcards
(91 cards)
A 50 yo male presents to the ER with 10/10 chest pain that is ripping and knife like. On exam, there are no murmurs. There is a decreased left-sided femoral pulse compared to the R side. BP in the R arm is 160/120 and 110/90 in the L arm. Which of the following radiologic findings would most likely be present? A. cardiomegaly B. widening of the mediastinum C. rib notching and a "3 sign" of aorta D. Kerley B lines E. Batwing appearance of hilum
B, widening of the mediastinum
*Classic description of aortic dissection
Systolic dysfunction (heart failure)
Dilated cardiomyopathy
Large pericardial effusions
All have what appearance on a CXR
Cardiomegaly
Rib notching and a “3 sign” of aorta are signs of…
Narrowing (coarctation) of aorta
- coarctation also usually has a systolic murmur that radiates to the back
- coarctation usually present with signs of HF
Kerley B lines and batwing appearance of hilum are seen in…
CHF
In evaluating a pt with progressive dyspnea, an echocardiogram is obtained, showing inadequate relaxation of the heart, a thickened pericardium and diastolic dysfunction. Exam shows increased jugular venous distention, especially with inspiration. Which of the following is most consistent with the suspected diagnosis?
A. pericardial knock
B. bilateral atrial enlargement
C. speckled myocardium
D. vegetation on the mitral valve
E. diastolic collapse of the cardiac chambers
A, pericardial knock
*classic description of constrictive pericarditis. in contrive pericarditis, the stiff, inelastic pericardium causes diastolic dysfunction by inhibiting the filling of the ventricles during diastole. The PERICARDIAL KNOCK is due to sudden cessation of ventricular filling by the stiff pericardium
the stiff, inelastic pericardium causes diastolic dysfunction by inhibiting the filling of the ventricles during diastole
Constrictive pericarditis
In constrictive pericarditis, the ______ is due to sudden cessation of ventricular filling by the stiff pericardium
pericardial knock
bilateral atrial enlargement and speckled myocardium are seen in..
Restrive cardiomyopathy
BOTH constrictive pericarditis AND restrictive cardiomyopathy are associated with _____ dysfunction
diastolic
and impaired diastolic ventricular filling
A speckled myocardium is seen with this common cause of restrictive cardiomyopathy
Amyloidosis
Vegetation on the mitral valve is associated with..
infective endocarditis
Diastolic collapse of the ventricles is classic for..
pericardial tamponade
*Kussmaul’s sign (increased JVP with inspiration) also see with pericardial tamponade
_____ ______ is associated with Beck’s triad (muffled heart sounds due to pericardial effusion), systemic hypotension (due to decreased forward flow) and increased jugular venous pressure (from increased back flow of blood)
Cardiac tamponade
Which class I anti arrhythmic has been shown to prolong depolarization and refractory period
Procainamide
A 43 yo male presents after a near syncopal episode and is currently dizzy. His EKG shows sinus bradycardia with a HR of around 40 bpm. Which of the following is the management of choice? A. observation B. permanent pacemaker C. IV epinephrine D. IV atropine E. IV amiodarone
D, IV atropine
*IV atropine is the first line tx for symptomatic bradycardia. Most bradyarrhythmias are thought to arise from vagal hyperstiumulation. Atropine is an anticholindergic drug that blocks the effects of Ach released by the vagus nerve and therefore is the first line agent in most cases
Which of the following drugs is the DOC to increase HDL levels? A. cholestyramine B. ezetimibe C. fenofibrate D. nicotinic acid E. simvastatin
D, nicotinic acid
HMG-CoA reductase inhibitors, used to lower LDL levels and have been show to reduce cardiovascular morbidity and mortality
“statins”
ie..Simvastatin
During a routine exam, an abdominal bruit is heard. What is the best initial study of choice if abdominal aortic aneurysm is suspected?
Abdominal ultrasound
A 43 yo male with a hx of hyperlipidemia, HTN and diabetes presents with crushing, substernal chest pain of 45 minutes of duration with radiation to the L arm. His prior ECG a month ago showed normal sinus rhythm with no abnormalities. Which of the following new ECG findings are considered an ST elevation myocardial infarction equivalent?
A. “m” shaped P waves in lead II, biphasic p waves in V1
B. R waves larger than S waves in V1, with the R waves measuring greater than 7 mm
C. Wide QRS complexes with broad, slurred R waves in V5 and V6 with a deep S wave in V1
D. Deep S waves in lead I, isolated Q waves in lead III, inverted T waves in lead III
E. Wide QRS complexes with an RSR’ pattern in leads V1 and V2. Wide S waves in V6
C, Wide QRS complexes with broad, slurred R waves in V5 and V6 with a deep S wave in V1
*these findings are consistent with a LBBB. LBBB are considered a myocardial equivalent because MIs can present with new bundle branch blocks
Why is a LBB considered a myocardial equivalent?
MIs can present with new bundle branch blocks
A pt with no noted risk factors for DVT develops unilateral R leg swelling. A venous doppler is performed, showing non-compressibility of the superficial femoral vein. What is tx for first episode of idiopathic DVT?
initiation of heparin with warfarin. Warfarin therapy continued for 6-12 months
Which of the following is most reliably seen in peripheral venous dz?
A. redness with dependency of leg
B. leg pain worse w ambulation
C. thin, shiny skin with loss of hair on foot
D. cool extremities
E. presence of a medial malleolus ulcer with uneven ulcer margins
E, presence of a medial malleolus ulcer with uneven ulcer margins
*medial ulcers are classically associated with peripheral venous dz
Medial ulcers are classically associated with..
Peripheral venous disease
Leg pain an cyanosis worse w dependency
stasis dermatitis with brownish pigmentation
peripheral edema with normal temp and pulses
Peripheral venous disease
