How soon after an acute upper GI bleed do you restart therapeutic anticoagulation in a patient with atrial fibrillation and a high thromboembolic risk (CHA₂DS₂-VASc ≥4)?
In real-world inpatient practice:~72 hours after endoscopic control for high-stroke-risk AF with stable hemoglobin and no rebleeding,Extending hold to 5–7 days if the lesion is high risk or the bleed was severe.
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...
Would you routinely initiate a high-intensity statin before discharge in an elderly patient presenting with a STEMI s/p revascularization who has an LDL below 70 mg/dL on no prior lipid-lowering therapy?
Yes. High dose stain therapy’s pleiotropic effects after a ‘plaque rupture’ event cannot be overlooked. Also, LDL-C in plaque rupture events (ACS, STEMI, NSTEMI) can be transiently lower due to the acute-phase response/inflammation. Starting high-intensity therapy ensures the ≥50% drop and addresses...
For stroke patients with ablated paroxysmal atrial fibrillation without known recurrence and ICAD, would you recommend dual antiplatelet therapy or anticoagulation with or without an antiplatelet agent?
Ablation treats cardiopulmonary symptoms, but it has not been adequately tested against anticoagulation for AFib-related stroke. Anecdotally, at least once a month, I will see a patient with an acute embolic-appearing stroke after their cardiologist has stopped their anticoagulation because they wer...
Do you have a strict age cut-off for not referring patients for CABG evaluation?
Simple answer: No. The risks and benefits of any procedure should be assessed and balanced for all patients, regardless of age, and decision-making should be undertaken in the context of the patient's overall health status, comorbidity burden, geriatric syndromes (esp. frailty and cognitive impairme...
When telemetry or ECG shows a newly prolonged QTc (e.g., >500 ms) in an otherwise stable hospitalized patient, how aggressively do you modify medications, electrolytes, or monitoring?
A newly prolonged QT can be easy to overlook amid the complexity of inpatient hospitalization, and when identified, I generally add it to the problem list so it remains visible during the admission and in future care. Although prolonged QT is associated with torsades de pointes, sudden cardiac death...
Is there a role for routine stress testing in intermediate-high risk CAD patients with a significantly elevated coronary calcium score who are otherwise asymptomatic?
Current data does not support stress testing in asymptomatic intermediate risk individuals in general and those with incidental CAC also do not have an indication for the test. ASCVD risk factor modification suffices.
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...
How do you explain the use of an AI scribe to patients the first time it is used in their care?
I use an AI scribe in my outpatient clinic, and around 90–95% of my patients agree to it. I obtain consent at the start of each visit and make it clear that it's completely optional—that they can say no at the start or change their mind at any point in the visit, with no impact on their care. I also...
Under what clinical circumstances, if any, would you prescribe fenofibrate along with statin therapy?
Yes, I do sometimes combine fibrates and statins. Usually, it’s in the setting of needing to treat severe hypertriglyceridemia with the fibrate in a patient who also has hypercholesterolemia and an indication for a statin. If a patient is on a statin and still has mild to moderate hypertriglyceridem...
