Are there other scenarios besides prior history of TIA or stroke or LV dysfunction in which systemic anticoagulation for LV non-compaction would be considered?
There is limited data in this area, but LV non-compaction by itself is not always an indication for anticoagulation. In addition to prior history of TIA, stroke or LV dysfunction, other conditions that anticoagulation should be considered include a history of atrial fibrillation or LV thrombus. The ...
In your clinical practice, do you find that patients with moderate dementia due to Alzheimer's see much benefit from increasing donepezil dosing from 10 mg/day to a higher dose such as 23 mg/day?
Personally, I do not see much benefit in increasing to 23 mg. To be fair, I do not do this very often, as our cognitive neurologists that I trained with during fellowship rarely did this, given their experience that 23 mg did not offer noticeably more benefit and often many more side effects. I have...
What are the reasons for SLE specific labs to turn negative?
I agree and appreciate the answers by Dr @Dr. First Last and Dr @Dr. First Last. My answer may be stating the obvious, but I think it is important to mention that lupus is not infrequently over-diagnosed and overtreated. Serologies are sometimes over-interpreted with low-titer antibodies labeled as ...
When should one consider obtaining a cardiac MRI in ischemic stroke patients?
This is a terrific question. Cardiac MRI is increasingly utilized in the diagnostic evaluation of ischemic stroke and can uncover clinically covert cardiovascular disease. The clinical utility in ischemic stroke is most in patients with concern for LV thrombus (low EF or recent anterior ST elevation...
What is your risk/benefit analysis when deciding on the appropriateness and timing for discontinuation of systemic anticoagulation in patients who underwent ablation for paroxysmal atrial fibrillation with CHADS2VASc score >2?
I typically do not discontinue oral anticoagulation in post-ablation patients with paroxysmal atrial fibrillation and a CHA₂DS₂-VASc score of >2. Catheter ablation is not considered a "cure" for atrial fibrillation; therefore, there is always a risk of recurrent arrhythmia. The patient may be asympt...
In adults ≥80 years with TSH 6–10 mIU/L and minimal symptoms, do you initiate levothyroxine, monitor, or avoid treatment entirely?
I tend to check free T4 in this situation. Aging is associated with some elevation in TSH value up to 10 mIU/L with normal free T4, and in those patients, levothyroxine is not needed. In some patients, I have seen it rise above 10 with normal free T4. Supplementing levothyroxine to lower serum TSH w...

What is a reasonable imaging modality for older patients with pAfib already on systemic anticoagulation outpatient but presenting with suspected cardioembolic stroke and TTE without evidence of LV thrombus?
Gold standard is TEE.
What is your approach to the management of chronic GI bleeding from AVMs in an elderly patient on DOAC for atrial fibrillation?
I would definitely strongly consider the left atrial appendage occlusion device in these patients. While usually these devices (such as Watchman) do require anticoagulation for about 45 days until the device has an endothelial layer form on it (we usually confirm with a CT scan or TEE), there are so...
Do you obtain routine blood cultures in a non-immunocompromised patient with community-acquired pneumonia who does not meet criteria for severe CAP?
Fabre et al., PMID 31942949, categorizes "non-severe community-acquired pneumonia" as low yield for bacteremia and therefore less critical and potentially wasteful/poor stewardship to obtain blood cultures, however do note that severe community-acquired pneumonia (CAP) falls into a moderate pre-test...
