A study of patients with heart failure found hyperkalaemia in 28%, with CKD significantly associated with elevated potassium. RAAS inhibitor and mineralocorticoid receptor antagonist prescriptions showed no association.

A randomised controlled trial found that nicorandil improved exercise capacity, coronary microcirculation, and quality of life in patients with heart failure with preserved ejection fraction and coronary microvascular dysfunction.

A multicentre Malaysian study identified six SCN5A gene variants among 40 patients with Brugada syndrome. Findings highlighted the potential role of genetic testing in risk stratification and family screening.

Remote ischemic conditioning reduced pulmonary fibrosis markers, inflammation, and tissue damage in a mouse model.

Artificial intelligence in cardiovascular medicine advances diagnostics, risk prediction, and clinical decision support.

A pilot study found facial video photoplethysmography estimated heart rate variability with strong correlation to ECG measurements, supporting the potential of contactless monitoring technologies.

A randomised trial found that breathing exercise, HIBIT, and combined exercise significantly reduced blood pressure in adults with hypertension, though combining the interventions offered no additional benefit.

A meta-analysis found subtle heart muscle dysfunction in people with HIV despite normal ejection fraction, highlighting the potential of strain imaging.
