How do you monitor for cardiac toxicity in patients taking osimertinib?
There are multiple studies that have explored the issue of cardiotoxicity from osimertinib. A large single-center retrospective observational cohort series from Taiwan, (n=401) compared a matched cohort of patients treated with osimertinib (n=253) to those treated with other EGFR TKIs (n=195) and fo...
What are your thoughts on the results from the AQUATIC trial which showed that the addition of aspirin daily + oral anticoagulation in patients > 6 months from PCI and with high atherothrombotic risk was associated with a higher risk of death, MI, stroke, coronary revascularization and acute limb ischemia, compared to oral anticoagulation alone?
I think AQUATIC is a well-designed definitive trial. It shows that in patients with chronic CAD (at least 6 mo. out from stent) who are also receiving anticoagulation (typically for AFib), the use of anticoag monotherapy is safer (statistically lower risk in terms of a composite endpoint as well as ...
Should we be more cautious with the use of GLP 1 R agonist therapy in patients with Type 1 diabetes mellitus and obesity given the increased risk of cardiovascular disease with high body weight variability?
There doesn't seem to be any evidence that GLP-1 RA would increase the risk of CV disease. Biologically, the benefits that have been shown in patients without Diabetes (the SELECT trial) should still be applicable for patients with Diabetes Type 1.The trials that didn't show much efficacy in glucose...
How do you advise patients on cardiotoxicity when they are expected to receive a low mean heart dose and low cardiac substructure doses with their radiation plan?
I would say something along the lines of: "Radiation therapy is an effective tool for treating your cancer. However, whenever we give radiation therapy, there is always some incidental dose delivered to the adjacent normal tissues. We cannot make the dose zero to all of the normal tissues. Thus, we ...
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...
