Ventricular arrhythmias during exercise in patients with mitral valve prolapse Mitral valve prolapse may be associated with ventricular arrhythmias, but little is known about the relationship between VA and exercise in these patients.

Risk and protective factors for stroke and transient ischaemic attack in patients with atrial fibrillation: an umbrella review of meta-analyses Atrial fibrillation is linked to significant morbidity and mortality, with ischaemic stroke being a leading cause of death. Identifying modifiable risk and protective factors may help reduce stroke incidence in patients with atrial fibrillation.

Chewing sugary gum may enhance the cardiovascular benefits of nitrate-rich vegetables For the first time, researchers at King's College London have discovered a link between chewing sugary gum after consuming vegetables high in nitrate, such as beetroot, spinach and kale, and lowering blood pressure.

Epigenetic drugs could protect blood vessels in obesity and diabetes Scientists from Zurich, together with colleagues from Italy, have proved that by acting on epigenetic "switches", early damage to blood vessels can be reversed. People with obesity and type 2 diabetes are at increased risk of cardiovascular complications. However, the danger depends not only on heredity, but also on how genes work.

Non-atherosclerotic myocardial infarction in hypereosinophilic syndrome: emerging insights and therapeutic approaches Hypereosinophilic syndrome (HES) is a heterogeneous disorder characterised by persistent, abnormal eosinophil elevation in blood and tissues, with multisystem involvement. Cardiac manifestations are frequent in HES and significantly worsen prognosis. Recent evidence establishes a direct link between HES and myocardial infarction (MI), demonstrating that HES induces MI primarily via non-atherosclerotic mechanisms.
