Prevalence of Subclinical Coronary Atherosclerosis in General Population

🇸🇪 25K randomly invited individuals w/o known CAD underwent CCTA
🇸🇪 51% women
🇸🇪 50 to 64 yrs
🇸🇪 #SCAPIS (the Swedish Cardiopulmonary Bioimage Study)…
🇸🇪 42.1% any CCTA-detected atherosclerosis

🇸🇪 5.2% any significant stenosis (≥50%)

🇸🇪 1.9% LM, prox LAD or 3VCAD

🇸🇪 8.3% any non-calcified plaque

🇸🇪 plaques most common in prox LAD

🇸🇪 Participants with only non-Ca plaques were rare (2.4%)…
🇸🇪 Prevalence of CCTA-detected atherosclerosis ⬆ w/ ⬆ #CAC scores

🇸🇪#CAC-positive participants:
- Most w/ low (11 - 100) or ultralow (1 - 10) scores
- median score 35 (IQR 8 - 126)

🇸🇪 participants w/ #CAC zero & interm 10-yr risk, 9.2% had CCTA-verified atherosclerosis

#Tweetorial #CMD #ACC21

#CMD shares similar RFs w epicardial atherosclerosis (traditional ASCVD RFs) & is associated with several biomarkers of inflammation, oxidative stress & coagulation

#Tweetorial #CMD #ACC21

There is significant overlap between #CMD & epicardial disease

Large number of patients w/ #CMD also have epicardial atherosclerosis (obstructive or non-obstructive) & epicardial endothelial dysfunction

#Tweetorial #CMD #ACC21

In our IVUS study:
✅ Most patients with #CMD had significant plaque burden
✅ Patients with #CMD had higher plaque burden & more diffuse atherosclerosis as compared to patients w/o CMD

⚡ Coronary Microvascular Dysfunction ⚡


📌 What Is #CMD
📌 Why Is #CMD Important❓

Based on my #ACC21 #ACCImaging presentation
#Tweetorial #CMD #ACC21

Let’s start by talking about angina

✅ Angina w/o obstructive CAD is very prevalent 

#Tweetorial #CMD #ACC21

✅ Angina ➡ poor prognosis
✅ Angina with no obstructive CAD = ⬆ risks of CV events compared to no angina, even after adjusting for traditional RFs & co-morbidities

⚡Selecting Between Different Functional Tests⚡

☢ vs 🧲 vs ⏺ ❓

🔘 Strengths/Limits of Lesion Specific vs Myocardial Ischemia
🔘 Comparing Dx Accuracy of Tests
🔘 Ischemia Testing in #INOCA
🔘 How to Select Best Noninvasive Test

☢ Issues with proposed #FFR threshold 0.8
☢ Exercise MPI correlates well with FFR but not at 0.8
☢ Benefit of FFR-guided revasc dominantly occurs w/ thresholds <0.8
☢ Quantification of lesion-specific #ischemia insufficient for patient mgmt
#ASNC2020 #cvNuc
Dr Di Carli

Lesion-specific #ischemia measurements (FFR/#FFRCT)

☢ Strength
Validated against ETT/MPI
Strong outcome data
Guidelines supported

☢ Limit
Controversial threshold (0.80 vs MPI-validated 0.66)
⬆ microvasc resist causes FFR pseudonormalization
