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.

An EMR-embedded cardiocerebrovascular registry integrated 27 modules, captured data from over 80,000 patients, and demonstrated feasibility for research, quality assessment, and patient reported outcome collection.

A prospective study found significant alterations in fetal cardiac function and Doppler parameters in severe preeclampsia, alongside earlier delivery, lower birth weight, and increased neonatal intensive care unit admission.

A UK study reports encouraging stent expansion with lithotripsy for severely calcified left main coronary disease.

A validation study found that contactless vital sign monitoring accurately measured respiratory and heart rates while maintaining performance across a range of realistic care scenarios.

A multimodal AI model combining tongue and facial photographs achieved excellent accuracy for coronary heart disease screening, outperforming single modality approaches while providing interpretable decision making.
