ITE - Cardiology Flashcards
Educational objectives for missed questions
Chronic venous insufficiency: Clues, Dx
Dx: clinical diagnosis with/without venous duplex u/s
clues: edema, dilated veins, thin/hyperpigmented skin, ulceration.
Hypertrophic cardiomyopathy: Clues, Dx.
Clues: ejection murmur at LSB (outflow obstruction), late systolic murmur at apex (MR), abnormal ECG
Dx: TT echo w/ asymmetric LVH and septal thickening
Peripheral vascular disease: Dx.
Dx: resting ABI < 0.9 (1.0-1.4 is normal), exercise ABI with >30mmhg or 20% drop. ABI > 1.4 uninterpretable and needs toe ABI
RIght ventricular infarction: Dx.
Sxs: hypotension, JVD, clear lungs
ECG: V1, V4R
Torsades de Pointes, drug-induced: Dx
Dx: Use of QTc prolonging meds
Ex: ondansetron, amio, quinolones, antifungals, antipsychotics, triptans
Wolff-Parkinson-White pre-excitation: Dx
Dx: symptomatic AVRT with preexcitation (delta wave)
Resynchronization therapy: Indications
HF w/ EF < 35%, NYHA class II-IV despite GDMT, sinus rhythm, LBBB with QRS > 150
AC for mechanical prosthetic valve
Lifelong AC and antiplatelet therapy. Goal INR 2.5, with risk factors or ball/cage valve INR 3.0, bioprosthesis INR 2.5
Bradycardia: Tx
Pacemaker for symptomatic and asymptomatic with high risk conduction abnormalities or heart block
Mitral stenosis: Ausculation
Loud S1, increased pulmonic component of S2, opening snap, diastolic rumble, low pitched murmur at apex
STEMI + signs of heart failure or shock
Emergent PCI, temporize with IABP or LVAD, reduce afterload, avoid beta blockers
STEMI + V-Fib
EP consult and ICD, predischarge
Atrial myxoma: Tx
Surgical removal
Cardiogenic shock: Tx
Early/Aggressive fluids with initial bolus of 30mL/kg
ICD: indications
HF w/ EF<35%, NYHA class II-III despite GDMT
PVCs: Tx
Reasurance
If high risk or > 10% of beats affected: Beta blocker or CC blocker, then antiarrhythmics, then ablation
PVD: Tx
Tx: Similar to CAD. Smoking cessation, DM control, HLD control. Aspirin, supervised exercise training (most effective way to improve fxnl status)
Claudication: Tx
cilostazol for claudication
Unstable angina: Tx
Tx: relieve pain, early risk stratification (TIMI risk score), if high risk –> PCI, if low –> medical management

Risk factors ranked
?
ECG abnormalities that contraindicate stress ECG:
ST segment changes, preexcitation, LBBB, VPCs, digitalis effect
digitalis effect:
?
Contra’s for adenosine (for single-photon emission CT)
reactive airway disease with active wheezing
Red flag murmurs
???diastolic or continuous murmur, cardiac symptoms (chest pain, dyspnea, syncope), or abnormalities on examination (clicks, abnormal S2, abnormal pulses)
Benign murmurs do what with standing
decrease
HCM, hemodynamics that affect
increases with decreased venous return
Maneuver to decrease venous return
standing
valsalva
MV prolapse, hemodynamics that affect
decrease venous return will move earlier in systole, increase intensity
