Myocardial flow reserve from PET imaging in patients with ischemic HF may identify those with a greater outcome benefit from CABG vs. PCI, according to data presented at the American College of Cardiology Scientific Session.

In the CIAO ancillary study of patients who were screened for the ISCHEMIA trials but were excluded because they had ischemia but no obstructive CAD, stress echocardiography results and angina frequency changed over time, researchers reported at the virtual American College of Cardiology Scientific Session.

New analyses of the ISCHEMIA trials of patients with stable ischemic heart disease presented at the virtual American College of Cardiology Scientific Session showed that results from the main trial were consistent across all anatomic and ischemia subgroups, but an invasive strategy raised death and stroke risk in patients with advanced chronic kidney disease.

Electromechanical wave imaging, a high-frame rate ultrasound technique, localized atrial and ventricular arrhythmias including premature ventricular complexes, Wolff-Parkinson-White syndrome, atrial tachycardias and atrial flutter, according to a study published in Science Translational Medicine.

The strongest predictor of nonfatal or fatal MI in patients who presented with stable chest pain was low-attenuation plaque burden, according to a new analysis of the SCOT-HEART trial presented at the American College of Cardiology Scientific Session.

A survey of advanced CV imaging programs found that they are as diverse in their size and trainees as the programs are in actual training and effect on subsequent clinical practice.

Patients with chronic kidney disease who were assigned recombinant human C1 esterase inhibitor, or rhC1INH, before coronary angiography had a lower risk for renal injury compared with those assigned placebo, with a favorable safety profile, especially in those with multiple comorbidities, according to findings from the PROTECT study published in JACC: Cardiovascular Interventions.

Automated CT-based algorithms predicted 5-year CV risk and overall survival in otherwise asymptomatic patients with greater efficacy than the Framingham risk score and BMI, according to a study published in The Lancet Digital Health.

Among men with HIV, those who used testosterone therapy had elevated risk for significant coronary artery calcium progression compared with those who did not, according to an abstract presented at CROI.
