Would you consider PCSK9 inhibitors for patients with elevated coronary calcium score or coronary calcification for primary prevention in lieu of statins/ezetimibe and/or bempedoic acid?

Absolutely! The VESALIUS trial confirms that lower is better even in people without a prior event. I wouldn’t use a PCSK9i in lieu of a statin, though. I would add it to the statin if someone’s LDL-C is still elevated. If someone has a high CAC score, I target an LDL-C and apoB <55 mg/dL. Ezetimibe ...

CCTA can not likely stand as a way of perfectly excluding ischemic heart disease, but neither can any test, such as ETT, SET, MRA, etc. As such, it seems attractive to individualize screening tests and even employ a complementary array of techniques.

Generally, the approach is to have the patient start their exercise regimen at a lower intensity and gradually increase it based on their tolerance.

There are a few options when using roto for the RCA or a dominant LCX. Upfront TVP if you want to play it safe. Pretreatment with aminophylline 100-250 mg 10 minutes. Test run without pre-treatment and having atropine and/or TVP nearby at the ready. Which you choose depends on gut instinct and how...

Do you prefer a loading dose of 300mg or 600mg plavix for patients presenting with NSTEMI or unstable angina about to undergo LHC?

Interesting question! As a rule of thumb, 600mg loads faster than 300mg. Therefore, it is more important when you anticipate your ballooning/stenting happening sooner rather than later (within minutes/hours). Per guidelines, Plavix is preferred over prasugrel/brilinta for stable angina (which was no...

Amiodarone has been studied in patients with prior TDP patients and found to be safe (small paper from Mattioni et al., PMID 2774388 at Northwestern at the time of my EP fellowship). Amiodarone has been found to be more effective when it prolongs the QT, and the 500 mS limit does not apply to it as ...

When would you consider AV nodal ablation in CRT-non-responders with persistent atrial fibrillation?

AV node ablation is the most definitive method for rate control. In this scenario where the patient already has CRT and is a nonresponder, what I do next depends on age of the patient, how symptomatic the patient is, whether the rates are elevated causing the CRT pacing percentage to be suboptimal a...

Would you consider transitioning patients older than 75 years of age with coronary disease from statins and/or other lipid-lowering agents to PCSK9 inhibitors given concerns for polypharmacy, provided their LDL levels remain at or below goal?

We do not have any data to suggest PCSK9i are better than statins, and all of the PCSK9i outcomes data are on top of statins. Data show generally that lower is better, and there isn’t a “floor” to benefit. That said, if I have someone on statin + ezetimibe who then gets LDL-C very low on a PCSK9i, I...
