Novel cardiovascular therapeutics and the risk of financial toxicity
Novel cardiovascular therapeutics have the potential to improve health outcomes, but financial toxicity from high out-of-pocket costs can limit the reach of these medications and worsen existing health disparities. Understanding the phenomenon of financial toxicity in treating cardiovascular disease is crucial to achieving health equity.

Novel drug therapies for atrial fibrillation
Atrial fibrillation is the most common sustained arrhythmia and imposes a substantial burden on patients and health-care providers. Clinical evidence suggests that antiarrhythmic therapy to restore and maintain sinus rhythm (rhythm control) can reduce adverse cardiovascular outcomes in patients with new-onset atrial fibrillation. As a result, a paradigm shift towards rhythm control over rate control therapy is emerging, increasing the clinical need for effective and safe antiarrhythmic drugs.

Anticoagulation in patients with atrial high-rate episodes
The risk of stroke in patients with atrial high-rate episodes (AHREs) depends on age, comorbidities and AHRE burden. Two randomized clinical trials on the use of oral anticoagulant therapy for stroke prevention in older patients with short and rare AHREs have reported conflicting findings on the efficacy of oral anticoagulation in this patient population, although both trials report a significantly increased risk of major bleeding with oral anticoagulation.

Factor XI inhibitors in patients with cardiovascular disease and a high risk of bleeding: a cautionary tale
Factor XIa inhibitors are being tested in clinical trials, with the assumption that these agents are as effective as direct oral anticoagulants but cause fewer bleeding events. Findings from phase II trials of direct inhibitors of factor XIa for the prevention of first-ever and recurrent ischaemic stroke or recurrent major coronary artery events suggest fewer bleeding events but with uncertainty about efficacy.

The need for new clinical trials of old cardiovascular drugs
While there is understandable excitement about the development of new cardiovascular drugs, an unmet and equally important need is to perform new clinical trials of old drugs, including to determine their longer-term effects and if and when they should be discontinued after years of use. New trials of old drugs can inform clinical practice and are much needed.
