1/9 @ACCinTouch 2023- Summary of key Lp(a) presentations.

On search function, there are 63 hits for “lipoprotein(a)”, and in ~1/3rd it was the primary focus.

1- 10 moderated posters
2- 3 oral presentations
3- 30 posters
4- 1 standing room only session
5- 19 “other”

I’m no Cardiologist, but even I picked up some learning points after being on the inpt heart failure service for the past 5 wks 🤷‍♀️🫀 - A series of “🦪 📿” on a variety of heart failure topics for the internist.

First one is on GDMT in HFpEF!

I’ve been seeing a lot of people quoting stats that show more athletes died in the last year than have died in the last 38 years. Is this true? No, let’s chat about it. A 🧵👇🏻

What should you call that elevated troponin?

This is NOT taught well and impacts more than you think.

🤔Why does heart failure with preserved ejection fraction (HFpEF) lead to sodium retention?

With reduced ejection fraction (HFrEF), decreased cardiac output (CO) leads to neurohormonal activation and sodium avidity.

If CO is preserved in HFpEF, what's the inciting event?

Why would adenosine, a purine nucleoside, be able to treat supraventricular tachycardias (SVT)?

And why are its effects so short lived (e.g. <2 seconds)?

The answers will change the way you think about this drug.

PMH: ESRD. Only 1 HD session/week. However, residual urine volume has now decreased substantially

On exam: BP 134/94, 2L O2,🧠✅, elevated JVP, decreased 🫁 sounds at bases, No murmurs, very mild edema. Functional left BC AVF

🤔Why does subarachnoid hemorrhage lead to deep/inverted "cerebral T-waves"?

This ECG finding is so dramatic. But as we will see, these patients often have normal hearts.

Why does an issue in the brain manifest on a test of the heart?

Here is the thread containg all master classes by @Lpa_Doc

ICU stories: Eldelry pt w CAD s/p multi-vessel PCI / DM2 / HTN presented to the ED w epigastric "burning". Symptoms much worse with laying down & while eating. No relief w iv famotidine; got relief with morphine. Troponin I elevated and peaked at 1,000 (nl <15). ECG:

There are ~350,000 sudden cardiac deaths (SCD) each year in the US (almost 1000 per day).

Most SCD occurs in older people with known coronary disease, but, sadly a minority of sudden deaths occur in the young.

Roughly 1500 people under 25 die of SCD each year in the US.

‘VT’ versus ‘SVT with aberrancy’.

The long list of VT "suggestive" ECG features is difficult to recall and apply in real time.

How can we simplify things?

Here is my ABCDE approach – five simple Qs to ask:

You see a patient on the ward with an exacerbation of heart failure.

The team has inserted a urinary catheter for fluid monitoring. What would you do?

🤔 Why do patients with acute myocardial infarction often present with diaphoresis (sweating)?

And, is there any significance when this symptom is present?

🎟️Let's have a look.

Should you give albumin with loop diuretics to augment diuresis?

I've been asked this three different times today so a quick🧵of my thoughts

#nephtwitter #MedTwitter @MedTweetorials

Yesterday, I discussed a pt who had subacute chest pain and dyspnea w/a group of learners

A pivot point in the case gave me some insight into the process of teaching reasoning

I'd love to share my experience #medtwitter #teachdx 1/

1/ You see a 56 y.o man with a h/o HTN, DM2 & HLD in your clinic. He’s been out of care for a while and you’re concerned about his ASCVD risk. You order a lipid panel, but wonder, “should I also add an ApoB level?”

Keep reading this @CardioNerds #tweetorial to learn more…!

1/10. Wat is the most important driver of worsening renal function in #HeartFailure ?

Look at #Tweetorial on central hemodynamic derangements in heart failure

#Cardiotwitter #Cardiology #FOAMed #Cardiorenal #MedEd #MedTwitter #Nephrology #ADVOR

Here’s a situation many of us have seen in the ICU or ED: “It looked like there was ST elevation on the monitor but when I took a 12 lead it was gone?!”

A STEMI went MIA? Here’s a #tweetorial all about why ST segments look different on monitors.

MINOCA :
MINOCA terminology came when has been recongnozed that angiograpghy may identified no signficant ( < 50% ) diseases artery in pts with MI

It’s 5-10% of all MI
Incidence 50000-100000 / year US

ICU stories: Middle-aged pt w remote hx of seizures had grand-mal sz at home & in the ambulance. Intubated for airway protection in ED; transferred to ICU. Placed on propofol. Overnight received 5 l NS & norepi gtt @ 0.1 & (ABx + steroids) for septic shock due to aspiration PNA.

🚨STAT 📟 I received recently in the @mghmedres CCU: “balloon pump helium leak alarm, blood in driveline.” In other words, the balloon had RUPRTURED. What do you do?

Here’s a quick primer on intra-aortic balloon pumps for your next rotation in the CCU! #CardioTwitter

LV thrombi (LVT)

👉Are associated with systolic dysfunction.
👉Can occur in both ischemic & non-ischemic cardiomyopathy.
👉Carry a significant risk of systemic thromboembolism.

Management is mainly anticoagulation, but would you choose WARFARIN or a DOAC?? A #tweetorial 🧵

Here's something we only do rarely--joint posting of an #accredited #tweetorial on @cardiomet_ce and @ckd_ce at the same time. What's the 🗝️ this time? Anderson-#Fabry disease, which affects both the #cardiovascular and #renal organ systems. Figure from 🔓https://link.springer.com/article/10.1007/s40265-021-01486-1

How often do you check for Primary Aldosteronism (PA)?

Chances are, NOT nearly often enough!

VA study reveals widespread undertesting...can we do better?

https://www.acpjournals.org/doi/10.7326/M20-4873

If you've seen 10 pt's with HTN ➡️ you've probably seen PA!

Let's review in this #medtweetorial

Why is torsemide my preferred loop diuretic when treating heart failure?

As a follow-up to a recent tweetorial on furosemide and gut edema, let me offer a 3-part ode to torsemide.

1/17
[Why] is furosemide susceptible to malabsorption from "gut edema"?

When a patient with heart failure is hospitalized with congestion I often hear "let's use IV furosemide; they're probably not absorbing the PO."

It's a comment unique to furosemide.

But is it accurate?

In our @JAMA_current editorial, we tackle a timely question in #CardioTwitter: should we recommend #apixaban or #rivaroxaban as first-line anticoagulant for #Afib?The two #DOACs are not interchangeable for bleeding or stroke. Let's review all RCTs & RWE🧵

ICU stories: Middle-aged pt w/o significant PMHx presented to the ED on a Friday afternoon w SOB/cough x 2 wks. Vaxed x2 but tested C19(+). BP 120/90, Sat 98% on 2 l/m. ECG: new-onset Afib/HR 140/QTc 500. CXR attached; read as RLL infiltrate. Labs: Na 125, BNP 800 (nl<100),

Last week a 50 y/o man is admitted to my service with alcohol withdrawal. No cardiopulmonary symptoms. Would you listen to his heart as part of your initial evaluation?

Why are statins administered at night?

In this tweetorial I'll discuss the mechanistic and historical reasons for the frequently used QHS dosing schedule. And why it's often unnecessary.

But before we get there, I'm curious: when do you prescribe/order/take statins?

70M presents with SOB. You're asked examine the cardiovascular system.

As you auscultate the heart you hear a murmur. What would you do next?

Open this thread and I'll share my approach.

70F presents with SOB. You're asked examine the cardiovascular system.

You look at the legs and detect peripheral oedema. What would you do next?
