Ticagrelor with aspirin dual antiplatelet therapy combined with intravenous thrombolysis in patients with ischaemic stroke in China (TAPIS): a multicentre, double-blind, randomised controlled trial
Ticagrelor-aspirin DAPT after thrombolysis improves excellent functional outcomes in acute ischaemic stroke; extends dual antiplatelet evidence to this population.
“Early DAPT significantly improved the rate of excellent functional outcome at 90 days (68.7% vs 62.0%; RR 1.11; p=0.0089) without a meaningful increase in symptomatic intracranial haemorrhage, representing an important advance in acute stroke care pending validation in broader populations.”

Highlights large eligible population for icosapent ethyl in ASCVD; extends trial criteria to contemporary cohorts.
This joint EAPC/ESC and ACC clinical consensus statement provides expert guidance on managing cardiovascular abnormalities in Masters athletes, addressing the limitations of applying standard guidelines to highly trained individuals.
New-onset postoperative atrial fibrillation management and outcomes: the VISION Cardiac Surgery cohort
New-onset postoperative atrial fibrillation after cardiac surgery is associated with a significantly increased risk of subsequent clinical AF and all-cause mortality at 1 year, highlighting the need for optimized long-term management.
“One of the goals of these guidelines was not to promote a single dominant therapy, but to provide a structured, phase-based approach that can reduce unwarranted practice variation while still allowing clinical judgment.”
Randomized trial evaluates accelerated pathways improving diagnostics in acute coronary syndrome.
“The results of MACROS-2 remind us that even when clinical pathways have been validated in rigorous trials, these pathways may not perform as well in some real-world practice setting. Laboratory turnaround times, clinical decision-making and limited resources in clinical practice can challenge eff...”
Optimal serum potassium concentrations in heart failure: an individual patient data meta-analysis
Hypokalemia <3.5 mmol/L flags higher mortality risk in HFrEF; extends RCT-pooled data supporting 4.2-5.0 mmol/L optimization trials.
Genome-first study compares familial hypercholesterolemia prevalence in African and European ancestry, highlighting different risks.
Endovascular Therapy for Post-Thrombotic Syndrome — A Randomized Trial
Endovascular therapy improves symptoms and quality of life in patients with moderate to severe post-thrombotic syndrome and iliac-vein obstruction at 6 months, though it is associated with an increased risk of bleeding.
“Many patients with PTS suffer in silence because few physicians are aware of this complication or know how to effectively treat it. This study suggests that even severe PTS is, in fact, a treatable condition in many patients.”
Prospective study evaluates implantation depth and clinical outcomes in TAVR, suggesting impactful insights for future procedures.
“The proximity of the prosthesis frame to the membranous septum and conduction system has been shown to be strongly depth-dependent, supporting a strategy of higher implantation to minimize mechanical interaction with the atrioventricular conduction tissue.”
This study evaluates the clinical, echocardiographic, and functional outcomes of transfemoral transcatheter mitral valve replacement in an international registry.
“When placed into the context of early TMVR experiences, which were predominantly performed via a [transapical] access, mortality rates appear favorable. This evolution represents a crucial step forward, offering a definitive valve replacement strategy to a frail, comorbid patient population previ...”
