How do you manage patients with atrial fibrillation having a thromboembolic infarct despite being on adequate anticoagulation?
This scenario is always challenging. In terms of anticoagulation, the efficacy of DOACs in preventing embolic events in AF patients is around 70%, which is impressive compared to warfarin but not foolproof. In cases of a second embolic event while on anticoagulation, two reasonable approaches are of...
How do you counsel an otherwise healthy patient on how soon they can go back to moderate exercise after a bilateral pulmonary embolism?
Generally, the approach is to have the patient start their exercise regimen at a lower intensity and gradually increase it based on their tolerance.
How do you approach exercise recommendations in a frail patient with chronic heart failure who has low baseline functional capacity?
Generally, the frail chronic heart failure patient will potentially benefit from a multicomponent and progressive approach to exercise. This should include balance training and flexibility in addition to resistance and endurance training. Studies have supported the benefit of exercise training in th...
What is your preferred follow-up imaging modality for an incidentally found thoracic aortic aneurysm measuring 4.4 cm detected on CT?
It depends on the location. If proximal, I would use echo. If more distal, I would prefer MRA.
How do you decide in older adults with newly diagnosed stage 2 hypertension when to start with two antihypertensive agents versus taking a more cautious approach due to concerns about potential orthostasis, frailty, or polypharmacy?
Starting Dual Therapy vs. a Staged Approach in Older Adults with Newly Diagnosed Stage 2 HypertensionThe core question isn't just how high blood pressure is; it's how much treatment this patient can safely absorb.In geriatric cardiology, cardiovascular risk reduction and treatment-related harm are t...
How do you approach the management and surveillance of mixed aortic valvular disease with moderate AS and AR, and threshold to refer for surgical intervention?
There are three parameters to consider for surgical management in moderate AS/AR: symptoms LVSF LV dilation Progressive pulmonary hypertension may also make surgery the appropriate decision.
Would you consider opting for beta blocker withdrawal to improve exercise capacity in patients with heart failure with preserved ejection fraction and chronotropic incompetence?
The short version of my answer is Yes, however, I will provide more insight into this: When considering beta-blocker withdrawal to improve exercise capacity in patients with HFpEF and chronotropic incompetence, the evidence and guidelines are nuanced. A prospective, randomized, controlled trial "Pre...
Would you perform a diagnostic paracentesis for first-time ascites in a patient with established CHF or pulmonary hypertension, but without apparent liver or other intra-abdominal disease?
Great question. Yes, we should perform a diagnostic paracentesis for first-time ascites, even in patients with established CHF or pulmonary hypertension, unless there is an obvious alternative explanation and the procedure is unsafe or technically not feasible. After the etiology is established, rep...
Do you require an ECG to assess the QTc interval before administering ondansetron to a hospitalized patient without a known cardiac history or QT-prolonging medications?
There is a nice "Things We Do For No Reason" article in Journal of Hospital Medicine on this: "Hospitalists need not order an initial and subsequent ECGs when administering standard doses of intravenous ondansetron for patients without significant risk factors for QTc prolongation. To assess risk fa...
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...
