Do shorter door-to-balloon (D2B) times impact outcomes in STEMI, if it's already less than 90 minutes, and to what degree (i.e., 30 vs 60 minutes would have a more significant impact)?
No. Shorter door-to-balloon times have not been shown to improve survival or outcomes in STEMI. The reason is that the other variable is the time from the onset of chest pain to presentation to a medical facility. This time is beyond the control of the medical system. For example, a patient waits 4 ...
How do you approach the management of patients with mildly elevated mPAP (21-24 mmHg) and PVR (2-3 WU) who may be at risk of progression, given the recent changes in the hemodynamic definition of pulmonary hypertension?
The "new" definition of PH with a cutoff of 20 mmHg is a very sensible change, based on the study by Kovacs et al., PMID 19324955, which showed that a mean PAP of 20 mmHg is already two standard deviations above the mean PAP in normals. Thus, the cut off of 20 mmHg makes more sense than 25 mmHg.To a...
How do you approach patients who identify so strongly with being sick or with a particular diagnostic label that it makes up a significant portion of their identity?
In many cases, the point at which this question is being asked is one at which the train has already left the station, and sickness as a way of life/career has set in. Unfortunately, with functional somatic syndromes, there is data suggesting that self-rated quality of life and functioning are lower...
How do you decide if a patient should get follow-up perfusion imaging after acute PE when they are minimally symptomatic?
I practice essentially as reflected in the most recent AHA/ACC/ACCP/CHEST/SCAI/SHM/SIR/SVM/SVN Guideline for the Diagnosis and Management of Acute Pulmonary Embolism in Adults.Figure 8. Evaluating Ongoing Symptoms Following Acute PE - concisely outlines the workup of patients with ongoing symptoms f...
How often, if at all, do you monitor a CBC with differential to assess peripheral eosinophilia in patients with type 2 inflammatory asthma who have been started on dupilumab?
For most patients, a baseline CBC with differential followed by a recheck at approximately 3 months aligns with the observed pharmacokinetics of eosinophil rebound. GINA 2026 notes transient blood eosinophilia occurs in 4–13% of patients, with rare EGPA cases potentially unmasked following OCS reduc...
How do you counsel women with cystic fibrosis on when pregnancy is reasonably safe after lung transplant?
Unfortunately, pregnancy after lung transplantation is never safe; what we usually mean by 'safe' is a close to 100% chance of a healthy baby and a healthy mother, and in the current era we cannot be certain of such odds. Having said that, there are situations where the risk of complications is lowe...
When do you consider extended steroid tapers for acute asthma or COPD exacerbations?
The data doesn't support extended tapers - 5 days of 40 pred equivalent are non-inferior, and extended courses can cause harm, including increases in mortality. I only use extended tapers for patients who have, in the past have rapid symptom recrudescence with the typical shorter course. Typically, ...
Do you routinely repeat imaging for PE after anticoagulation treatment to establish a new baseline?
We only do imaging if the patient is symptomatic still after a few weeks or has persistent chest pain or clinical signs of pulmonary hypertension. Rarely I have seen recurrent or progressive thromboembolic disease on anticoagulation. Another possible reason if the patient needs to go to surgery in t...
What would be your approach to percutaneous intervention for acute plaque rupture and cardiogenic shock for a patient with cirrhosis and severe thrombocytopenia?
Thrombocytopenia is not an absolute contraindication to indicated percutaneous coronary intervention (PCI) and the antiplatelet therapy which it obligates. In a scenario such as this one -- cardiogenic shock complicating an acute myocardial infarction -- PCI is indicated as a life-saving procedure. ...
Do you recommend avoidance of occupational/environmental exposures in patients with pulmonary sarcoidosis?
The best assessment of occupational exposures associated with pulmonary sarcoidosis comes from A Case Controlled Etiologic Study of Sarcoidosis (ACESS). This is nicely summarized in a state-of-the-art article that lists occupations and exposures with both positive and negative associations between o...
