For years, Circulation: Population Health and Outcomes has published research that helps shape cardiovascular health across communities and health systems. We're excited to announce Dhruv S. Kazi, MD, MSc, MS, (@kardiologykazi) as the next Editor-In-Chief.

Reweighting to national demographics barely changed K-M survival curves → data are nationally representative K-M curves largely matched an independent referral center BCH → data are externally valid 🔗ahajournals.org/doi/10.1161/… 📝Article by @KidsHeartHealth et al @AHAScience

No national registry tracks long-term survival after congenital heart Sx. How to estimate it? Researchers built & validated K-M curves, standardized using KID weights, log-rank comparison with BCH)& found 7 operations w/ reliable coding (≥70% concordance) Read More ⬇️

⬇️odds for oac: dementia, prior bleed, renal disease ⬆️odds for oac: HF (though HF in CHA₂DS₂-VASc) Bleeding risk/frailty seem to drive prescribing > stroke risk itself 🔗ahajournals.org/doi/10.1161/… 📝Article by @p_gouda1 & @manesh_patelMD et al

High-risk AF pts & OACs: study finds gap is big Only 57.4% of 161K high-risk AF patients (PCORnet, 2015-19) on OAC at Dx. Of those started, only 45.6% on yr later. Of those untreated, only 12.5% ever on one Read More⬇️

After full adjustment, Black women still ~2.7x more likely to develop HTN The other unexplained ~75%? Likely unmeasured structural and systemic factors, including structural racism 🔗ahajournals.org/doi/10.1161/… 📝Article by @JD_Borrowman & @MCarnethon et al. @AHAScience

New CARDIA analysis: Black women develop postpartum HTN more often than White women. Does that gap come down to measurable risk factors? Measured risk factors explain only ~25% of the Black–White gap in postpartum HTN Read More ⬇️

These real-world data may help refine future pediatric CPR guidelines & improve survival as less than half of children survive in-hospital cardiac arrest 🔗ahajournals.org/doi/10.1161/… @ryan_w_morgan @AHAScience (3/3)

Exploratory targets linked to improved survival: ❤️ CC rate: 130–160/min vs 100-120 cc/min ❤️ CCF >90% vs >80%. ❤️ Infants <1 yr: CC depth 23–27 mm vs. ≥40mm for age <1year & ≥50mm for age ≥1year (2/3)

Are current pediatric CPR targets optimal? Targets based on adults? In ICU-RESUS study AHA-recommended chest compression (CC) rate, depth & chest compression fraction (CCF) were not associated with better outcomes Read More ⬇️ (1/3)

EVT moved closer to patients but does broader local access outweigh the potential benefits of concentrating complex stroke care at fewer, high-volume centers? ahajournals.org/doi/10.1161/… @AHAScience

New paper maps stroke care networks in California & finds expanded networks beyond major referral hubs to more hospitals after endovascular thrombectomy (EVT) became standard of care in 2015 This reduced hospital transfers & increased EVT use Read More ⬇️

MA patients had better outcomes despite greater socioeconomic disadvantage but why? Differences in patient selection, unmeasured TAVR risk, coding intensity, & underlying AS prevalence may contribute. ahajournals.org/doi/10.1161/… @AHAScience

Does Medicare coverage type influence outcomes after #TAVR? Using Medicare claims, paper compares MA vs FFS: 🔹 TAVR utilization 🔹 Patient & hospital characteristics 🔹30–150-day & 1-year outcomes Read More⬇️ @AHAScience @ChristinaLalani @rwyeh @rkwadhera @djc795 @JMKimMD

Reported leadless pacemaker adverse events rose faster than implantations raising safety concerns @deviceevents @rfredberg ahajrnls.org/4rxjJbU

2/ BP control highest-yield target in subset with high 30-year risk: PAR 57.8% women/28.9% men. @MohanSatishMD @sbradley_heart @iamritu @AHAScience @kardiologykazi @bnallamo @lcolantonio @uabsoph @nyphospital @WeillCornell

1/ Analysis of REGARDS proposes adding a 30-year CV risk estimate to standard 10-year risk to ID subset of 45–59 year-olds for earlier prevention, suggesting a 3-tier risk stratification approach bit.ly/3SZjx8o (Read More...🧵)
