Everything you need to know about acute pericarditis

🆕 ACC/AHA Guideline on the Management of Dyslipidemia offers a comprehensive “one-stop shop” for addressing the evaluation, management & monitoring of individuals w/ dyslipidemias.

AHA/ACC #PulmonaryEmbolism Guidelines out today!
⭐️ Patients with acute PE who are asymptomatic (AHA/ACC PE Category A) can safely be discharged home from the ER
⭐️Early hospital 🏥 discharge is generally recommended for patients with acute PE who are symptomatic but have a low clinical severity score (AHA/ACC PE Category B)
⭐️Symptomatic patients with acute PE & ⤴️ clinical severity score should be hospitalized to optimize treatment strategies.

🫀 CardioNugget: V

ereckei (aVR) Algorithm for Wide-Complex Tachycardia

Goal: Is this VT or SVT with aberrancy?

Physiology key: SVT usually has a fast start (His–Purkinje early). VT often has a slow/fragmented start (myocardium-first).

Step through lead aVR (in order):
1) Initial R in aVR? → VT
The vector suggests ventricular origin.

2) Initial r or q ≥ 40 ms in aVR? → VT
“Slow start” = cell-to-cell myocardial activation.

3) Notching on the initial downstroke of a predominantly negative QRS in aVR? → VT
Fragmented early conduction (scar/anisotropy) vs smooth Purkinje.

4) Vi/Vt ratio (first vs last 40 ms of QRS in aVR):
Vi/Vt ≤ 1 → VT (slow early, relatively faster late)

#CardioNugget:

“Northwest Axis” = Clue for VT

What it is:
✅ Extreme axis deviation (“northwest axis”)
QRS positive in aVR and negative in Lead I + aVF.

How to spot it fast:
Look at I and aVF: both negative → axis is “northwest”
Confirm: aVR is upright

Why it favors VT:
SVT with aberrancy usually still uses the His–Purkinje system, so the axis is often more “physiologic.”

VT activates the ventricles from myocardium, spreading in an abnormal direction → can drive the net vector superior/rightward → upright aVR + negative I/aVF.

🧵 Can we have cardiac dysfunction despite a normal ejection fraction?

Even with a normal LV ejection fraction (LVEF), early myocardial damage can exist — especially in conditions like systemic sclerosis, lupus, or diabetes.

Let’s explore how we can detect it early — before symptoms appear.

Lets explore about Speckle Tracking Echocardiography (STE) 👇

Pericardial Tamponade vs Constrictive Pericarditis ➡️Spot the Difference

Tamponade
⬇️
Accumulation of fluid in the pericardial space
⬇️
↑ intrapericardial pressure
⬇️
impairs diastolic filling throughout the cardiac cycle (early and late diastole).
Doppler shows blunted E and A waves due to restricted filling.

Constrictive Pericarditis
⬇️
Thickened, non-compliant pericardium
⬇️
rapid early diastolic filling that abruptly halts once volume limit is hit.
Doppler shows prominent E wave, reduced A wave, classic for constriction.

Recognizing the echocardiographic filling patterns is essential for diagnosis.

🔹 #CardioNugget:

LV Mass by Echo
👉 LV mass (g) =
0.8 × 1.04 × [(IVS + LVID + PWT)³ – (LVID)³] + 0.6

IVS = interventricular septal thickness (mm)
LVID = LV internal diameter in diastole (mm)
PWT = posterior wall thickness (mm)

🧠 Key takeaways:
1.04 = myocardial density (g/cm³).
0.8 = correction factor for LV shape assumptions.

LV mass index (g/m²):
Men >115 → LVH
Women >95 → LVH

Prognostic: LV mass predicts CV events better than wall thickness alone.

🚫 When NOT to use cube formula:
-LV is asymmetric or remodeled (e.g., regional wall motion abnormalities, infarction, eccentric LVH).
-LV is not a true ellipsoid (e.g., dilated cardiomyopathy, distorted geometry).
-Poor acoustic windows → inaccurate dimension measurements.
👉 In such cases, 2D or 3D echo or CMR is preferred.
