CCTA isn’t just for diagnosis, it’s a PCI playbook. Excellent new review details how #CCTA offers shorter cases, less contrast/radiation, fewer geographic misses, better stent sizing, and a reproducible workflow you can teach.

❗ Coronary calcium scoring is a great way to risk stratify patients for the #1 cause of death, but many insurance plans still don't cover this test. 👏 Here's a new expert statement in @JACCJournals that calls on payers to provide coverage. The time is now for progress. buff.ly/UCWJZG5

💥 New review from @TheLancet on Dx of #CAD. 👉 Bottom line: The field continues to shift toward plaque-centric #CCTA, with functional tests layered on for ischemia, reflecting a more comprehensive approach to chronic CAD. www.thelancet.com/journals/lan... @drmarthagulati.bsky.social #CardioSky

🚀 New #EACVI consensus statement on multimodality imaging for #HCM from @s_e_petersen @cardim_nuno. #Echo, #CMR, #CCT, and #PET each add unique value across diagnosis, symptoms, prognosis, screening, and treatment monitoring. Key points👇

Michael Hadley @hadleymd.bsky.social · 04/11/2025

💥 Myocardial Blood Flow (#MBF) isn't just a #PET thing anymore. #CCT and #CMR are in the game. 🚦 Angina isn't always explained by epicardial stenoses. Quantification of MBF can detect other causes (#ANOCA), like microvascular disease, HCM, or transplant vasculopathy.

We’re doing CT before most TAVRs, but we’re only cashing in on the “planning” part. This review argues we should be squeezing the rest of the dataset for prognosis and longitudinal care. www.journalofcardiovascularct.com/article/S193... What else is sitting on those scans? 👇

🤔 Thought-provoking piece in @CircAHA from Kole & Joshi 🫀 A growing group of patients with subclinical atherosclerosis falls in between traditional "primary" and "secondary" prevention. I've heard of "prevention 1.5" or "plaque-informed prevention." How about the following classification system?👇

🪦 Ischemic heart disease remains the #1 cause of death worldwide 💥 That's 8.9M premature deaths or 136M years of life lost in 2023 alone 💊 We need a better strategy to detect and prevent ischemic heart disease 👏 Thanks to GBD for another incredible report: www.thelancet.com/journals/lan... #CCTA

Michael Hadley @hadleymd.bsky.social · 14/10/2025

💥 As coronary CTA volumes increase, we must keep radiation exposures as low as reasonably achievable. ☢️ AHA/ACC/SCCT recommend a goal of median CCTA dose ≤4 mSv, which has been achieved in multicenter trials without compromising quality.

💥 Photon-counting detector CT offers good diagnostic accuracy for detecting ISR, overcoming artifacts that have plagued prior generations of scanners. 🔬 In a blinded study of 283 stented lesions, PCD-CT, as compared to cath, demonstrated NPV of 96.4% and accuracy of 88.9% for ISR ≥50%.

🧲 #CMR can identify cardiac allograft vasculopathy effectively and non-invasively. 🔬 In this study of 110 patients s/p heart transplant, quant myocardial perfusion reserve <2.2 had NPV 100% and AUC 0.88 for significant CAV, as compared to cath. doi.org/10.1093/ehjc... @SCMR @EHJ #CardioSky

🚨 Preventing first heart attacks may need a rethink. 🔬 In this massive study of 4.6 million people with their first heart attack: --18% had no standard modifiable risk factors --51% had no warning symptoms beforehand --63% weren't on preventive meds (only 22% on statin)

Michael Hadley @hadleymd.bsky.social · 07/10/2025

💥 The SCOT-HEART 2 trail could transform how we identify those at risk of heart attacks. 🔬 Trial randomizes asymptomatic patients ages 40-70 with ≥1 risk factors to either #CoronaryCTA or standard care, with appropriate therapies, looking for primary outcome of heart attack.

🚨Late-presenting ostial LAD STEMI, imaged 7-days later with #CMR. Here's the #LGE. ❓Would you call thrombus? Microvascular obstruction? Intramyocardial hemorrhage? Or a combination of these? @NorthwellHealth @LenoxHill #cardiotwitter

❓As Plaque Analysis roles out nationwide for #CCTA, providers are asking "How will this change clinical management?" ✔️The DECIDE registry provides one framework: Total Plaque Volume determines level of therapy. 🔬More research is needed to show impact on hard outcomes. #cardiotwitter @NorthwellHealth

Important multicenter study in #EHJ #CMR outperforms societal recs for ICD placement in cardiac sarcoidosis 📈AUC=0.86 for 5-yr risk of fatal/life-threatening arrhythmias ⚡Highest risk = abnl LVEF + LGE that is multifocal, septal, subepicardial, or involves RV freewall buff.ly/Nc2upbU #cardiotwitter

Nice review in #EHJ on LGE and SCD by @DrMarchlinski et al. buff.ly/GeU589P 🫀Good reminder that in CAD: LGE predicts SCD better than LVEF; absence of LGE has a high NPV for SCD 🔭Looking ahead, digital twins made from CMR data undergo virtual inductions to uncover arrhythmia risk #cardiotwitter
