What is your preferred method for subclinical CAD screening prior to initiation of class IC antiarrhythmic drugs for atrial fibrillation?
Flecainide and propafenone are the IC agents in use for atrial fibrillation. Encainide and moricizine were predominantly used for ventricular arrhythmias and encainide was pulled a long time ago due to proarrhythmia concerns and I believe Ethmozine stopped being marked many years ago.The CAST trial ...
Is there a particular PVC/NSVT burden on inpatient telemetry in which you would consider discharging a patient with a LifeVest post-STEMI with newly reduced LVEF <35% while optimizing GDMT?
The PVC/NSVT burden is not part of the equation for post-STEMI LifeVest. The guidelines clearly state that if you have an EF of <35% and are within 40 days of an MI, or any revascularization within the past 90 days, the wearable defibrillator is a class IIb indication while optimizing GDMT. If the p...
How should we approach the recommendation of intermittent fasting for weight loss in patients with pre-existing cardiovascular conditions, given the observed association of increased CV mortality with eating durations of less than 8 hrs?
I will admit my prejudice on this topic. I don’t understand the biologic plausibility of shortening the time during which meals are consumed to 8 consecutive hours a day with no snacking for 16 hours a day (but without calorie restriction) in order to lose weight. This would be like saying “have bru...
What is your preferred intervention for diffuse severe ISR involving two layers of stent?
Drug coated balloons
How do you approach the use of benzodiazepines in patients with chronic medical illnesses that may be susceptible to respiratory compromise (e.g., CHF, COPD, ILD)?
It’s a very good question and answers may vary among different specialty providers. Yes, a slow or gradual weaning of the benzodiazepines would be advisable. When they reach lower doses the taper should be even slower over weeks or longer. There is a risk for not weaning them off benzodiazepines inc...
When do you usually introduce conversations regarding tracheostomy placement in patients with refractory status epilepticus, or other conditions where one may anticipate delayed awakening?
It depends on the underlying pathology and how long the patient is expected to have impaired airway reflexes requiring prolonged mechanical ventilation. In the Setpoint 2 trial, among patients with severe stroke receiving mechanical ventilation, a strategy of early tracheostomy (</= 5 days), compare...
Which regimen would you recommend for a young patient with node-positive, triple-negative breast cancer with significant anthracycline-induced cardiomyopathy?
I would consider the NeoPact regimen, consisting of 6 cycles of docetaxel, carboplatin, and pembrolizumab, which is currently being directly compared to the Keynote-522 regimen in the SCARLET trial. Given some immune-related cardiac risks of pembrolizumab, I would strongly recommend that the patient...
What is your typical approach to the use of beta blockers in the setting of recent cocaine use amongst patients presenting with cocaine-related MI, arrhythmias, or new-onset heart failure?
I favor using or continuing non-selective beta-blockers in patients presenting with acute cardiac manifestations of recent cocaine use. My preferred agent in this setting is carvedilol.
What are standard selection criteria for patients who are eligible for heart transplantation?
Some of the selection criteria for isolated heart transplant are age </= 70 years, controlled DM (Hba1c </=7.5, BMI </=35 kg/m2 (may vary according to institution), absence of irreversible fixed pulmonary hypertension (PASP> 50 mm Hg and either TPG > 15 mm Hg or PVR > 3 WU), no illicit drug use in t...
What is your preferred mechanism for venting the left ventricle in patients on VA-ECMO?
Based on recent studies and evidence in the literature, my preferred approach for venting the left ventricle in patients on VA-ECMO would be guided by the individual patient's clinical scenario, with a cautious inclination towards using the intra-aortic balloon pump (IABP) over Impella. This prefere...
