#CardioTwitter #Cardiology
#Heartfailure 💔 is a clinical syndrome that results from a structural or functional impairment of one or both ventricles. Ventricular filling and ejection are thus, hampered.
On the basis of EF, HF is classified into
1️⃣Heart failure with reduced ejection fraction(HFrEF)
2️⃣Heart failure with improved ejection fraction(HFimpEF)
3️⃣Heart failure with mildly reduced ejection fraction(HFmrEF)
4️⃣Heart failure with preserved ejection fraction(HFpEF)

Classically placed in the arm
May be placed in the leg (eg in #pediatrics /neonates – which may then terminate in the infrarenal IVC/iliacs)
#criticalcare #cardiovascular
- Lower infection rate then central lines
- Used in the outpatient setting
- Can be used for several weeks to months
- Duration of PICC lines may be from 4 weeks to 6 months
(although they have been known to be functional for more than 300 days)

🧵 Thread: The Future of Assessing Systemic Microcirculation in Cardiogenic Shock (CS) 🩺🫀

1/ Hey Twitterverse! Today, I want to talk about an exciting topic in cardiology & ICU: the role of evaluating systemic microcirculation in CS. 🌡️🫀 #ICU #Cardiology #Microcirculation Image
2/ CS is a life-threatening condition in which the heart is unable to pump enough blood to meet the body's metabolic needs.… Image
3/ Traditionally, assessment of the macrocirculation (e.g., BP, LVEF, CO) has been the focus, but new research suggests that assessment of the microcirculation is the next step.💡

We have been doing a series of studies, led by @jeb1426, on sex differences in symptom complexity & phenotypes in acute myocardial infarction (AMI) and their impact on diagnosis & treatment. Some imp findings. #Cardiology #MedTwitter @YaleMed @YaleCardiology @yuan_lu1 Image
@jeb1426 @YaleMed @YaleCardiology @yuan_lu1 In one study, we found 'Women had more variation in unique symptom phenotypes than men' greater symptom complexity & longer door-to-balloon times. Non-chest pain symptoms are more frequent in women, potentially delaying STEMI recognition. @CircOutcomes… Image

1/ Had a great time writing this @EPLabDigest article with @DrCJBradley

2️⃣ different perspectives (IC And EP) using different devices (watchman/ amulet) for LAAC in the community center.

Let’s take a dive into two different LAAC programs #Tweetorial
2/ #LAAC has come a long way over the past few years and now we have two main players in the space

🔸 @bostonsci #watchman
🔸 @AbbottNews #Amulet

Both are very effective and each has pros/cons

My center focuses on Watchman FLX while @DrCJBradley center focuses on Amulet……
3/ Historically #EPeeps has taken the driver seat in this space (rightfully so) due to experience with the LA/transeptal. HOWEVER the new gen #IC/structuralist have become a vital part of the team.

#LAAC programs require:

AV dissociation, capture beats and fusion beats are all hallmarks of ventricular tachycardia

A simple understanding 👇

#CardioTwitter #Cardiology #Medtwitter
What’s a “capture beat” ?

During ventricular tachycardia, sometimes the SA nodal firing takes control of independent ventricular depolarization for brief moment, as this happens, “CAPTURE BEATS” appear. They are nothing but a brief moment of normal looking P-QRS pattern Image
Whats a “fusion beat” ?

During ventricular tachycardia, sometimes the SA nodal impulse and the independent ventricular impulse combine together to create a mix looking P-QRS pattern called fusion beats.

Seeing a lots of post-Covid cases like this: 30s-40s, pleuritic chest pain, mild shortness of breath, negative ecg and troponin, low positive or positive D-dimer. CT scans almost always (-) for pulmonary embolism. What to do? #medtwitter #Cardiology…
This study shows Dimer can be elevated for 10 weeks after infection. Reminds me of what @BinitaKane saw last year, but these patients are not hypoxemic at rest or on a walk-test. I've been sending for cardiac consult/ echo/stress test, but is a V/Q scan or resp consult needed?
Forgot to attach the thread where this is discussed last year:

Afectación cardiaca en enfermedad de Fabry en 🧔🏻‍♂️de 52 años. EKG con PR corto + HVI. @VazyurVasquez @MDBeni @CuitlhuacArroy1 @ImagenCardiaca @LiliPosadaM @ASE360 @smexcardiologia @Cardiotweets83 @SISIACOficial @Enrique_Berrios #echofirst #Cardiology #Cardiotwitter
La enfermedad de Fabry es un desorden lisosomal de transmisión ligada al cromosoma X debido al déficit de la enzima alfa galactosidasa A, con acumulación multisistémica de globotriaosilceramida (GB3).
La afectación cardiovascular suele manifestarse en forma de HVI, fibrosis miocárdica, ICC y arritmias, que limitan la calidad de vida y constituyen las causas más frecuentes de muerte. En la imagen se observa los estadios de la afección cardiaca

Psychosocial #Stress increases the risk of #stroke

1. A longitudinal study (2007-2021) was conducted on 27,000 people from 32 countries belonging to various continents to assess the relation of self-reported stress and risk of various types of stroke
#MedTwitter #neurotwitter
2. Increased stress at home and at work (within the previous 12 months) increased the risk of stroke by 95% (1.95 times) and 170% (2.7 times) respectively, as compared to no self-reported stress. Recent stressful events increased the risk of stroke by 1.3 times.
3. This association was consistent for all stress domains, including work stress, home stress, and financial stress. The association was independent of socioeconomic status, occupation, and educational level & remained significant after adjustment for cardiovascular risk factors.

Dato importante 🚨
Si tienes un paciente hospitalizado con falla cardíaca aguda y está cerca del egreso hospitalario, entonces INÍCIALE a la mitad de la dosis los medicamentos esenciales en falla cardíaca crónica (IECA/ARA2/ARNI + BB + ARM) y cítalo a mas tardar en 2 semanas🧵👇
Si bien las guías recomiendan un seguimiento ambulatorio temprano (2 a 4 semanas) luego del egreso por falla cardíaca aguda, el nivel de evidencia de esta recomendación es bajo y no aclaran cómo se debe iniciar y titular los medicamentos de falla cardíaca crónica.
Sin embargo…👇
El estudio STRONG-HF mostró que los pacientes asignados al grupo de cuidado de alta intensidad (iniciando la mitad de las dosis antes del egreso y titulando a la totalidad de la dosis a las 2 semanas) presentaban menos el desenlace primario.

Three #cardiology cases with diagnostic ECGs in our resus room today and some learning points for emergency clinicians

#ecg #ekg
1. Sudden onset palpitations

ECG shows regular narrow complex tachycardia with rate around 140
We suspected this was atrial flutter
Rather than subject a patient to the horror of iv adenosine (which only reveals flutter - it can’t convert it), we moved the ECG limb leads around to get a ‘Lewis lead’ which better shows atrial activity

Empagliflozin is now my go-to SGLT2i for pts with #diabetes and #CKD or #CHF, over cana or dapa or ertu.


and EMPEROR-Reduced and EMPEROR-Preserved
EMPA-KIDNEY is unique because it enrolled GFR 20-45 *without* proteinuria whereas others (DAPA CKD, CANVAS) enrolled pts with CKD+proteinuria, though DAPA-CKD conducted a subgroup analysis for UACR < and > 1000
The primary outcome was a composite of progression of #kidney disease (defined as #ESRD, a sustained decrease in eGFR to <10, a sustained decrease in eGFR of ≥40% from baseline, or death
from #renal causes) or death from #cardiovascular causes

1/ For the fellows and #ACCEarlyCareer!

It’s a coronary thrombus! When to consider thrombectomy? What do you do? Let’s walk through this…#Tweetorial

#Cardiotwitter #Cardiology #STEMI
2/ Middle age patient with hx of CAD and PCI to LAD presents with significant SOB and elevated Hs-Trop. No chest pain. No ECG changes. Echo with inferior hypokinesis.

Here’s the diagnostic with a JR4.

Notice the filling defect in the RCA. This is thrombus. How do we know?
3/ Keys of #thrombus on angiogram

🔑 contrast staining
🔑 Lack of calcium on non con image
🔑 ovoid filling defect (complete lumen)

🧵 on the Algorithmic Localisation of Accessory Pathways from ECG

A concept I’m getting to grips with made easier by a beautiful review by #Crinion & @adribaran in Card Electrophysiol Clinic (PMID 33161996)

#EPeeps #MedEd #Cardiology
🫀Considerations of AP localising algorithms:

A. Only apply to manifest antegrade AP & not concealed AP which conduct retrograde

B. Algorithms focused on atrioventricular AP & not other rarer AP

C. Depend on the degree of preexcitation with

D. Cautions with multiple APs
🩻 Anatomic Nomenclature

- AP locations is described in the LAO view
- Older algorithms use anatomical descriptions derived from the Valentine heart position & not attitudinally correct nomenclature which can be confusing

Joint British Society consensus recommendations for magnetic resonance imaging for patients with cardiac implantable electronic devices.

1. Recommendations for MRI workflows in patients with cardiac implantable electronic devices.

#CardioEd #Cardiotwitter #CardioScience
2. Workflow for provision of MRI to patients with MR Conditional cardiac implantable electronic devices.

3. Suggested additional steps required prior to performing MRI for patients with CIEDs that are MR Unlabelled or do not fulfil MR conditions.

#CardioEd #Cardiology #Cardio
4. Suggested consent statement for implanting cardiologists when potentially implanting an MR Unlabelled device, or revising/upgrading a device that may then become MR Unlabelled.
