Is there a potential role that hormonal replacement therapy can play in contributing to the development of SCAD?
Spontaneous coronary artery dissection (SCAD) is an infrequent if not rare cause of acute coronary syndrome (ACS). SCAD is estimated to occur in 0.7-1.1% of acute infarctions. In patients, especially female, who present with an ACS but have a low risk profile for coronary disease, SCAD should be con...
In a patient with decompensated heart failure requiring urgent non-cardiac surgery, how much volume optimization do you pursue preoperatively, and at what point does the risk of further surgical delay outweigh the benefit of continued diuresis?
I would recommend preoperative placement of a Swan-Ganz catheter in this situation to guide perioperative management, including intensity of diuresis and use of intravenous inotropic agents and/or vasodilators.
Are there still clinical situations in which you deliberately treat patients with a DOAC besides apixaban?
Thank you for your question. Apixaban has been my preferred agent for a long time for patients requiring therapeutic anticoagulation. Apixaban’s lower bleeding risk was shown prior to and now has additional evidence to support this with the COBRRA trial. The risk is also ameliorated by the safety in...
When you identify new atrial fibrillation in a hospitalized patient that spontaneously converts to sinus rhythm within 24–48 hours, and the patient has a CHA₂DS₂-VASc score of 2–3, how do you decide whether to initiate anticoagulation and/or discharge with a wearable cardiac monitor?
This is a tough one. I think the easier part is who should get a wearable cardiac monitor? I think the answer is pretty much everyone since the recurrence rate is around 30% in one year - and if it recurs, it predisposes to strokes, and I'd likely provide anticoagulation per AHA/ACC based on CHA₂DS₂...
For patients admitted with acute decompensated heart failure, do you wait until the patient is euvolemic before ordering a TTE?
For patients with newly diagnosed CHF, I always get a TTE prior to discharge to establish a baseline study. It would help me identify valvular disease and pulmonary hypertension, or other structural problems. If a TTE would help you distinguish CHF from other volume overload conditions, then I would...
Would you favor CT AV calcium score or dobutamine stress echo for a patient with symptomatic AS and an aortic valve with normal SV/SV index, Vmax 3.4m/s, AVA < 1.0 cm2, and mean gradient < 40 mmHg?
This scenario appears to be one of normal flow, low gradient severe aortic stenosis(NF-LG AS). This is one of the least understood variants of low gradient aortic stenosis. The most important focus should be on avoiding measurement errors during echocardiography, which may lead to underestimation of...
What GDMT do you recommend for patients with AL amyloidosis and systolic heart failure?
You are correct that cardiac amyloidosis patients do not tolerate most of the GDMT. SGLT2i may be helpful for both diuresis as well as HFpEF, and we do try to start this. Generally, they do not tolerate ARB/ACEI or even beta blockers. We find that torsemide seems to have better GI absorption and thu...
Similar to the HFA-ICOS risk stratification tool for patients on chemotherapy, are there cardiac risk calculators available for use in patients starting immunotherapy?
Currently, there are no validated risk calculators available for predicting ICI-induced cardiovascular immune-related adverse events (irAEs). Several risk factors have been reported to be associated with a higher risk of experiencing cardiac irAEs. These risk factors include a history of preexisting...
Can cardioversion be safely performed for recurrent atrial fibrillation in patients who have undergone left atrial appendage clipping during CABG, if they are not on chronic anticoagulation anymore?
Based upon the LAAOS III trial, we know that patients with left atrial appendage ligation at the time of cardiac surgery have a lower risk of stroke compared to those who did not when anticoagulation is continued in both groups. The data is much less clear for complete cessation of anticoagulation a...
Is active cocaine or methamphetamine use a contraindication to implanting defibrillators?
As a general principle, I do not think that a potentially life-saving intervention should be withheld in patients with substance use disorders (including tobacco, alcohol, cocaine, methamphetamine, or even IV drugs) unless the risk of the intervention outweighs the anticipated benefit. Further, I be...
