Survival Proportional Odds Outperforms Cox Regression in High-Heterogeneity Heart Failure Trials: Insights from DAPA-HF and DELIVER

A critical reanalysis of the DAPA-HF and DELIVER trials reveals that the survival proportional odds model provides greater statistical power and more robust treatment effect estimates than traditional Cox regression in heart failure populations characterized by high risk heterogeneity.

Precision Medicine in Atrial Fibrillation: Biomarker-Based ABC-AF Risk Scores Fail to Outperform Standard Care

A large-scale registry-based RCT reveals that tailoring atrial fibrillation treatment using the biomarker-driven ABC-AF risk score does not significantly reduce stroke or death compared to current standard guideline-based care, highlighting the complexities of implementing precision medicine in clinical practice.

Routine Cerebral Embolic Protection Fails to Mitigate Stroke or Cognitive Decline in TAVI: Results from the BHF PROTECT-TAVI Trial

The landmark BHF PROTECT-TAVI trial reveals that cerebral embolic protection (CEP) does not reduce periprocedural stroke or cognitive impairment following TAVI. This large-scale study challenges the routine use of embolic filters, suggesting that neurological outcomes are influenced by factors beyond intraprocedural debris capture.

Abluminus DES+ Fails to Achieve Non-Inferiority Against XIENCE EES in Patients with Diabetes: Results from the ABILITY Diabetes Global Trial

The ABILITY Diabetes Global trial demonstrates that the Abluminus DES+ sirolimus-eluting stent failed to meet non-inferiority compared to the XIENCE everolimus-eluting stent in patients with diabetes, showing significantly higher rates of target-lesion failure and revascularization at 12 months.

Mechanical Thrombectomy Superior to Anticoagulation Alone for Rapid Right Ventricular Recovery in Intermediate-High Risk Pulmonary Embolism: Results from the STORM-PE Trial

The STORM-PE trial, the first randomized controlled trial of its kind, demonstrates that computer-assisted vacuum thrombectomy (CAVT) significantly improves right ventricular recovery and reduces clot burden compared to anticoagulation alone in patients with intermediate-high risk pulmonary embolism.

Targeted Education Enhances Rhythm Control Adherence in Atrial Fibrillation but Faces Limits in Stroke Prevention: Insights from STEEER-AF

The STEEER-AF cluster-randomized trial reveals that structured professional education significantly boosts adherence to complex rhythm control guidelines in atrial fibrillation, though it shows no significant impact on stroke prevention where baseline performance is already high.

Mavacamten Redefines Long-Term Outcomes in Obstructive Hypertrophic Cardiomyopathy: 128-Week Results From the VALOR-HCM Trial

The 128-week follow-up of the VALOR-HCM trial demonstrates that mavacamten provides sustained relief from LVOT obstruction, promotes favorable cardiac remodeling, and significantly reduces the need for invasive septal reduction therapy in patients with symptomatic obstructive hypertrophic cardiomyopathy.
