What is your approach to managing incidental hypertension without evidence of end-organ damage in hospitalized patients?
Approaches to managing inpatient HTN without evidence of end-organ dysfunction have evolved over the years. I worked with some attendings who felt strongly about treating. There was a great JAMA IM article that explored this very question for non-cardiac patients. Link here: Rastogi et al., PMID 333...
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...
How do you manage anticoagulation/antiplatelet therapies with strong indications for uninterrupted therapy in the setting of urgent procedures?
If anticoagulation is absolutely contraindicated because of the bleeding risk of the procedure, then "bridging" will usually make the most sense, most of the time, with low molecular weight heparin such as enoxaparin. If dual antiplatelet agents are contraindicated, particularly in the first month a...
How do you think about using contraction alkalosis as a mark of achieving goal diuresis?
Thank you for your insightful question. Residual congestion at discharge for patients treated for decompensated heart failure is associated with increased rates of readmission and mortality. While I do occasionally use the development of metabolic alkalosis as a marker of decongestion, a review of t...
What treatments options may be considered in patients with POTS who also need daily diuretics to treat heart failure and are already wearing compression garments?
Given the epidemiology of POTS and congestive heart failure, you are far more likely to see a patient with neurogenic orthostatic hypotension and CHF than POTS and CHF. I have an article on NOH and CHF in Autonomic Neuroscience 2020. The principals are basically the same however because the managem...
How do you counsel patients who develop DVT or atrial fibrillation requiring anticoagulation when being treated with lecanemab or donanemab?
I believe until further data/studies are available, I would prefer not to use anticoagulation (at least long term) without comprehensive discussion among other treating physicians depending on the indication. The lecanemab appropriate use recommendations (Cummings et al., PMID 37357276) recommend ag...
Is there any evidence to support further uptitration of dobutamine beyond 5 mcg/kg/min for patients with advanced HF and/or cardiogenic shock, or should further investigation into potential MCS be considered at that point?
When a patient with acutely decompensated heart failure and shock is exhibiting insufficient perfusion in spite of a given level of support, whether pharmacologic or mechanical, it is appropriate to pause and ask why. Options at this point could include an escalation of inotropic therapy (dose escal...
What is your approach to a newly diagnosed LBBB in individuals >70 years old who are free of any signs or symptoms of heart disease and without other significant ASCVD risk factors besides age?
The presence of BBB; whether IVCD or RBBB or LBBB, signifies infranodal conduction delay from a myopathy. That myopathy may be hypertensive (LVH) or ischemic (LAD disease) or something less common (inflammatory etc). The ideal test would evaluate anterior septal LV thickness and vascular flow; it’s ...
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?
This is an interesting question and a challenging situation for a patient. I think that the ideal scenario would be for the patient to be euvolemic clinically prior to surgery. I am very aggressive with intravenous diuretics. I think that a discussion with the patient, with the surgeon, and with ane...
