What drug has been shown to improve walking distance in pt with PAD? Contraindictaions?What is the first line tx for walking in PAD?
Cilostazol (PDE-3 inhibitor); Contraindicated if EF \<40% due to similar MOA as milrinone which has worse outcomes with CHRONIC use in HFrEF; supervised walking program
156
What medications should be held prior to a stress test?
Beta blockers because they can blunt the HR response and pt may not meet 85% MPHR to have an adequate test; hold 24-48 hours prior
157
What is the tx of severe MR with LV dysfunction?
Assuming that the valve is suitable for repair, mitral valve repair is the treatment of choice if there is LV dysfunction, even if asymptomatic (Of note, EF should be at least 30%)
158
MC cardiac anomaly associated with Turner Syndrome?
Bicuspid AoV
159
When is CABG best for CAD?
Patients who are symptomatic despite optimal medical tx and who have specific angiographic findings of L main dz, multivessel dz with pLAD involvement; or DM pts with triple vessel dz and concomittant reduced LV fxn (FREEDOM)
160
When is a moderate to high intensity statin indicated in a pt with DM?
Age 40-75 with DM whose CV risk is \>= 7.5%
161
What is a diagnostic consideration in a pt with newly diagnosed Afib i.e. on random EKG to determine if they may need rate control?
Can do a Holter monitor to see if the average HR is \>110 bpm as the goal should be less than 110
162
What is a likely etiology of acute heart failure with atrial arrhythmias in a pt within 2 years of heart transplant?
Acute Allograft Rejection (development of afib and aflutter common); allograft vasculopathy more common and may just have the HF sx and is SLOWER TO PROGRESS and needs angio
163
In what cases of acute heart failure are steroids useful?
If it is due to sarcoidosis, giant cell myocarditis, or eosinophilic myocarditis; it is not helpful for viral myocarditis; note that NSAIDS, colchicine, and asa are options for pericarditis do NOT pick this for myocarditis
164
What is the appropriate mgmt of thrombolytic therapy failure for MI? What may indicated that pt has had failure of thrombolytics?
Transfer to a PCI capable center for rescue PCI; Failure to resolve CP, lack of improvement in ST elevations, no reperfusion arrhthmias, or clinical deterioration/cardiogenic shock
165
In addition to aspirin and a statin, the typical med started in a pt with symptomatic CAD (i.e. stable angina) is \_\_\_\_\_\_\_\_\_\_
BB; BB is first line then can try long-acting CCB (dilt/verapamil) or nitrate then ranolazine
166
How do you diagnose subclavian steal syndrome?
See reversal of flow in the vertebral arteries with doppler US, can see BP diff of \>15 mmHg between the arms
167
The INTERHEART study assessed 9 modifiable risk factors for MI, which one was the worst?
Dyslipidemia; Dyslipidemia \> smoking \> psycho stress \> DM \> HTN \> obesity \> EtOH \> physical inactivity \> diet low in fruits/veg
168
Explain an Austin Flint murmur
It is a diastolic decrescendo aortic regurgitation murmur with a diastolic rumble due to premature closure of the MV from the regurgitant jet causing functional MS
169
What are some evidence of severe AS on TTE? Tx?
Aortic valve area \<1 cm2, mean transvalvular pressure gradient \>40, Vmax (flow) \>4 m/s or AVA by BSA index \<0.6 cm2/m2
