EAT‑Lancet Diet and Recurrent Cardiovascular Events: Lower Stroke Risk and a Signal for Myocardial Infarction in Patients with Established CVD

Two cohort analyses suggest greater adherence to the EAT‑Lancet diet is linked with lower recurrent non‑fatal vascular events—notably stroke—and that education and sex modify long‑term cardioprotective benefits of this sustainable, plant‑forward pattern.

Immediate Coronary Angiography After Out‑of‑Hospital Cardiac Arrest Without ST Elevation Shows No 1‑Year Survival Benefit — IPD Meta‑Analysis of COACT and TOMAHAWK

An individual patient data meta‑analysis of COACT and TOMAHAWK (n=1,031) found no 1‑year survival benefit to immediate coronary angiography versus delayed/selective angiography after out‑of‑hospital cardiac arrest (OHCA) without ST‑elevation; no patient subgroup showed a clear differential benefit.

LMNA Variant Type and Location Shape Arrhythmic Risk in Cardiomyopathy: Truncations Confer Higher VA Risk; Tail-domain Missense Variants Appear Lower Risk

In 718 patients with pathogenic/likely pathogenic LMNA variants, truncating variants carried higher risk of malignant ventricular arrhythmia independent of position, while missense variants in the tail domain and exons 7–12 had lower arrhythmic and heart-failure events, suggesting genotype-location refines risk stratification.

Shared Genetic Vulnerability: Polygenic and Monogenic Contributions to Peripartum, Alcohol-Induced, and Cancer Therapy–Related Cardiomyopathies

A large multi-cohort genetic analysis shows that both rare monogenic variants and a high polygenic score for dilated cardiomyopathy (DCM) are enriched in peripartum, alcohol-induced, and cancer therapy–related cardiomyopathies, supporting a shared genetic susceptibility unmasked by diverse environmental stressors.

Common, Rare and Somatic Genetic Drivers Together Double 5‑Year Atrial Fibrillation Risk: Toward an Integrated Genomic Model (IGM‑AF)

A UK Biobank whole‑genome study finds polygenic, rare monogenic, and somatic (CHIP) variants each independently associate with incident atrial fibrillation (AF); combined genomic profiling plus clinical risk (CHARGE‑AF) improves discrimination (C=0.80) and reclassification.

Intracardiac Echocardiography Is Noninferior to Transesophageal Echocardiography for Thrombus Screening in Atrial Fibrillation Ablation — with Added Safety and Efficiency Gains

A multicenter randomized trial (N=1,810) found intracardiac echocardiography (ICE) noninferior to transesophageal echocardiography (TEE) for preventing periprocedural thromboembolism in AF ablation, while reducing bleeding related to transseptal puncture, fluoroscopy time, preprocedural wait, and patient anxiety.

Sự viêm vi mạch bẩm sinh sớm và kích hoạt nội mô xác định đặc điểm miễn dịch chủng khác sau ghép tim lợn sang người

Phân tích đa chế độ của hai quả tim lợn đã được chỉnh sửa gen 10 gen được ghép vào người đã chết não cho thấy sự viêm vi mạch bẩm sinh sớm với kích hoạt nội mô và hồ sơ phân tử phù hợp với tổn thương do kháng thể mặc dù không có C4d trong mao mạch. Một cách tiếp cận chẩn đoán chính xác có thể cải thiện giám sát ghép.

Early Innate Microvascular Inflammation and Endothelial Activation Define the Xenoimmune Signature After Pig-to-Human Heart Transplantation

Multimodal analysis of two 10-gene–edited pig hearts transplanted into brain-dead human recipients revealed early innate microvascular inflammation with endothelial activation and a molecular profile consistent with antibody-mediated injury despite absent capillary C4d. A precision diagnostic approach may improve graft surveillance.

Elevated Blood Pressure in Adolescence Predicts Dose‑Dependent Coronary Atherosclerosis in Middle Age: Implications for Early Detection and Prevention

A Swedish cohort study of 10,222 men linked adolescent blood pressure to coronary atherosclerosis by CCTA ~40 years later; higher systolic BP in adolescence, even in the ‘elevated’ range, was associated with greater odds of severe (>50%) coronary stenosis in middle age.
