Would you consider opting for beta blocker withdrawal to improve exercise capacity in patients with heart failure with preserved ejection fraction and chronotropic incompetence?
The short version of my answer is Yes, however, I will provide more insight into this: When considering beta-blocker withdrawal to improve exercise capacity in patients with HFpEF and chronotropic incompetence, the evidence and guidelines are nuanced. A prospective, randomized, controlled trial "Pre...
When would you consider switching to or adding on a PCSK9 inhibitor to lipid-lowering therapy following hospital discharge for acute coronary syndrome, in light of the results of the VICTORION-INCEPTION trial, provided LDL is still not at goal?
I don’t think the trial really changed my mind on this. I never really worried about not having ACS patients in the original phase 3 trials, so I had already been using inclisiran when I could in recent ACS patients. I would never switch from a statin to a PCSK9i. Statins are cheap, effective, and w...
For atrial fibrillation patients with high risk of CVA who cannot tolerate full dose AC due to bleeding, do you consider low dose/extended dosing anticoagulation even if they do not meet age/GFR criteria for a dose reduction, if Watchman is not readily available as an option?
Most drugs, including anticoagulants, have a dose-response. Therefore, one could argue that even though DOACs were not studied at low doses, except in defined sub-groups such as the very elderly, using such a dose in other situations may have some benefit. The problem is that without data, we simply...
What is your preferred anticoagulation/antiplatelet regimen for younger patients presenting with ACS, found to have an acute thrombotic event requiring aspiration thrombectomy without need for stent deployment?
Spontaneous in situ thrombosis of a coronary is rare, especially in the absence of a plaque rupture event. Malignancy-related coronary thrombotic occlusion, even with DOAC semi-compliance, is pathophysiologically difficult to understand, because coronary arteries are relatively high-flow areas, fili...
For septic patients with borderline heart failure, how do you individualize the decision about additional fluid boluses after the initial resuscitation?
For septic patients with borderline heart failure, the decision about additional fluid boluses after the initial resuscitation requires careful observation and monitoring. My approach has been to administer 500 cc-1 liter of fluid, and then assess volume status (physical exam, JVP, or POCUS, which i...
Are there instances where TAVR should be considered for patients with moderate AS and HFrEF?
Perhaps this is better asked provocatively; did AS (with less than severely elevated gradients) result in a decline in LVEF, or did moderate AS cause HFrEF? In the absence of an alternate cause of LV dysfunction, AS may be the only causative elephant in the room. Other subtle markers of AS severity,...
Is dexrazoxane recommended for cardioprotection in AYA patients with Hodgkin lymphoma who are receiving anthracyclines as part of their upfront therapy?
This is a good question that reflects the growing body of evidence in favor of dexrazoxane cardioprotection being safe and beneficial (Chow et al., PMID 26014292; Getz et al., PMID 32343641). For AYAs with Hodgkin lymphoma, doxorubicin remains a key component of therapy even for lower stage disease ...
What is your approach when a patient has concomitant acute decompensated heart failure and rapid atrial fibrillation?
Is the patient stable? If not stable, then I would move towards immediate cardioversion. If stable (good BP) but poor oxygenation, then diuretic with consideration of metoprolol, digoxin, or amiodarone. If unable to tolerate BB due to lower BP, then would lean towards amiodarone or digoxin. Anticoa...
What factors do you consider for patients on an individual basis when establishing a post-cardiac arrest MAP goal after ROSC is achieved, considering some may benefit from higher MAP goals for optimal cerebral perfusion?
I generally aim for a MAP of 70. However, I am more concerned with ensuring end organ perfusion and will track urine output, lactate, mental status, and LFTs in addition to the physical exam (cool vs warm and absence of mottling). MAP goal adjustment should also be considered in instances with a wid...
What is your approach to treating patients with decompensated heart failure when their hypervolemia is refractory to oral furosemide?
Depending on the oral dose, it may just be a problem of underdosing or even perhaps non-adherence. We would typically transition to intermittent IV Lasix dosing with close monitoring, if minimal response, we can double the dose to try and get to the ceiling effect of Lasix, depending on the renal fu...
