Does the presence of diastolic dysfunction guide subsequent pharmacological, pacing and ablative therapies for atrial fibrillation?
For the majority of patients with atrial fibrillation, symptoms are generated by the elevated heart rates rather than the irregularity or the loss of the atrial contribution to ventricular filling. The exception to this is patients with heart failure with preserved ejection fraction (diastolic dysfu...
When do you think physicians should seriously consider prescribing PCSK9 inhibitors for the prevention of heart attack and stroke in people with ASCVD or diabetes, based on the results of the VESALIUS-CV trial?
Although I checked 'high lipoprotein (a) as a reason to go with a PCSK9 first, I would almost never do it is practice. Statins first and then add a PCSK9 if LDL is above my goal for the patient. I might use a lower dose of the statin to get 35% lowering and then add the inhibitor if the patient was ...
What is your approach to checking preoperative cardiac biomarkers such as troponin and BNP?
While now recommended as a means of risk stratification for those over 65 years with cardiac risk factors across all three guidelines (AHA/ACC, CCS, ESC), we mostly reserve the use of biomarkers preoperatively for patients in whom we are on the fence for obtaining additional cardiac workup. We view ...
Besides treadmill, what other exercises may be considered for post-exercise ABIs, and are their diagnostic parameters identical to standard post-exercise ABIs?
2 minutes of Toe-raises has been demonstrated to be an acceptable alternative to exercise ABI's.
What serologic biomarkers do you send to assess for sarcoidosis at baseline and/or during flares, in patients where it may correlate with disease activity?
Elevated ACE, dihydroxy vitamin D, and soluble IL2r levels have been shown to correlate with disease activity, but it is important to keep in mind that the sensitivity and specificity are variable and they should never be used in isolation to diagnosis or assess disease activity in sarcoidosis. The ...
How do you approach a patient with sarcoidosis who cannot tolerate steroids and who is developing ILD?
As with most questions about sarcoidosis, clear understanding of the relevant clinical context should first be established. While interstitial lung disease (ILD) is a common manifestation of sarcoidosis, it often can be safely monitored without treatment, and so radiologically identified sarcoid ILD...
How would you manage cardiac sarcoid with intolerance/contraindications to methotrexate, azathioprine, and mycophenolate/mycophenolic acid and that has proven refractory to adalimumab and infliximab as determined by PET?
I think it would be important to know the doses of the medications 'failed'. Similarly to allopurinol dosing and gout prophylaxis 'failures', I find most patients I see for consultation with this story are not on high enough doses, need combo therapy, or are not on the medication long enough. Meth...
For those who don't have access to addiction medicine, have you considered using naltrexone for the treatment of stimulant use disorder in your primary care clinic?
I am an addiction medicine clinician, and this is my general approach for treatment of stimulant use disorder (which is almost entirely methamphetamine use in my location of Portland, Oregon). Most of my patients have co-use of opioids, so they are typically unable to get onto naltrexone, and I reco...
What is your approach to distinguishing a Jarisch-Herxheimer reaction from a delayed anaphylactoid reaction?
As with most things in medicine, this is context-dependent. The Jarisch-Herxheimer reaction is a systemic inflammatory response to the death of bacteria (most commonly associated with spirochetes and in particular, syphilis), typically in the hours following antibiotic administration. This response ...
What medications would you have a patient avoid with an IgE mediated reaction to cyclobenzaprine?
The mechanism of immediate hypersensitivity to cyclobenzaprine is likely MRGPRX2-mediated rather than IgE-mediated. MRGPRX2 is a G-protein coupled receptor (GPCR) predominantly expressed in human mast cells. Upon activation, MRGPRX2 triggers mast cell degranulation and anaphylactic reactions. MRGPRX...
