AUG 21RaoCirculation Arrhythmia and Electrophysiology
Left atrial appendage closure showed no significant difference in any stroke compared with OAC (RR 1.08; 95% CI 0.82-1.42; P=0.60), but increased ischemic stroke and reduced nonprocedural bleeding.
LAAC raises ischemic stroke risk while halving nonprocedural bleeding versus OAC; challenges composite-endpoint reliance and extends calls for individual-outcome RCTs.

AUG 25OyamaCirculation Reports
Wide interlesion distance fails to meet noninferiority versus standard distance for acute PVI success.
May support 6-mm ILD PVI with TactiFlex in paroxysmal AF; leaves open durability and outcome confirmation.

AUG 25FerroCirculation
PFA linked to ~0.4% higher absolute 30-day stroke or TIA risk vs RFA.
May warrant caution with pulsed field ablation for AF; leaves open confirmation in randomized trials.
EFDr. Enrico G. Ferro
Cardiologist, Beth Israel Deaconess Medical Center
The 30-day rate of stroke/TIA was significantly higher for PFA cases (10 events; 0.47%) compared with RFA (2 events; 0.10%) in both unweighted and propensity score–weighted analyses (weighted risk difference, 0.36% [95% CI, 0.03%–0.70%]; P=0.03).

Higher post-MI adherence to healthy dietary patterns is linked to ~33% lower total mortality.
Supports post-MI dietary counseling; leaves open whether interventions improve survival in trials.
ŞADr. Şekip Altunkan
Internal Medicine Specialist, Private Clinic, Ankara
A 33% reduction in mortality is not a marginal gain; it is a fundamental shift in trajectory. Most importantly, this research dispels any sense of fatalism following a cardiac event. Even if your diet was poor before your heart attack, improving it afterward is independently associated with better survival.

AUG 24RazaCirculation Heart Failure
RV dysfunction in PH-HFpEF is linked to ~8-fold higher risk of 1-year death or HF hospitalization.
Provides hypothesis-generating mechanistic insights into right ventricular failure in PH-HFpEF;.
BSDr. Bradley Serwer
interventional cardiologist, VitalSolution
This study may signify a paradigm shift in our understanding of heart failure with preserved ejection fraction. Patients who concurrently develop pulmonary vascular remodeling and right ventricular dysfunction may represent a fundamentally distinct and significantly elevated risk group compared to those with standard uncomplicated heart failure with preserved ejection fraction. The main clinical message from this study is that heart failure with preserved ejection fraction should be viewed as a disease of the entire cardiopulmonary system, rather than simply a disease isolated to the left ventricle.

AUG 21PatelCirculation Arrhythmia and Electrophysiology
Endocardial PFA achieves mitral isthmus block in only 45% of patients, often requiring ethanol infusion.
Endocardial PFA yields durable transmural mitral isthmus block in only ~52% of cases; leaves open the role of adjunctive strategies in AF ablation.

New RCT protocol evaluates AI coaching versus supervised HIIT and passive monitoring for cfPWV and VO2 max.
Planned RCT tests wearables for lifestyle adherence targeting cfPWV and VO2max; leaves open clinical efficacy in CVD prevention.

AUG 25RowinCirculation
ICDs deliver appropriate therapy to ~16% of HCM patients alongside low disease-related mortality.
Supports ICD consideration in selected HCM patients; leaves optimal risk stratification open for prospective trials.

Tirzepatide is linked to ~29% lower stroke risk versus other GLP-1RAs in AF and T2D.
Tirzepatide-associated lower cerebrovascular risk in AF with T2D; hypothesis-generating, needs randomized confirmation before practice change.

AUG 25Maldonado-GarciaHeart
Higher VAT links to incident CVD, with accelerated heart ageing explaining ~14% of this risk.
Imaging phenotypes may refine CVD risk assessment beyond BMI; leaves open whether they improve outcomes or warrant routine use.
