Boston Children’s criteria IDs kids at risk for arrhythmias during stress tests

Clinically significant arrhythmias are rare during exercise stress tests (ESTs) in pediatric heart patients, researchers reported in JACC: Clinical Electrophysiology, but those most at risk for life-threatening events can be identified from a set of predefined risk factors like cardiomyopathy and ventricular dysfunction.

Image-guided atherectomy system for smaller vessels gains CE mark

Avinger announced on Oct. 18 its Pantheris SV atherectomy device has gained CE mark approval, allowing it to be sold commercially in Europe. The system extends the plaque-removing technique for peripheral artery disease to smaller vessels with diameters between 2 and 4 millimeters.

Bedside troponin test can rule out AMI within 15 minutes

A point-of-care troponin assay that yields results within about 15 minutes was equally effective at ruling out acute myocardial infarction (AMI) as a high-sensitivity troponin I test performed in a laboratory setting, researchers reported in JAMA Cardiology.

AHA, AMA recognize 802 practices for efforts to control hypertension

A year after its launch, the American Heart Association and American Medical Association’s joint Target: BP Recognition Program, an effort to reduce the rate of uncontrolled hypertension in the U.S., has reached 802 members, the organizations announced this week.

Prior PCI does little to affect CABG outcomes

Despite past research suggesting a history of percutaneous coronary intervention (PCI) could complicate coronary artery bypass grafting (CABG) outcomes, a study published in the Journal of the American Heart Association Oct. 16 reported prior PCI has little to do with how a patient recovers from subsequent surgeries.

Why Cleveland Clinic began screening carpal tunnel patients for cardiac amyloidosis

Cleveland Clinic researchers identified amyloid deposits in 10.2 percent of patients undergoing carpal tunnel release surgery, suggesting biopsies of hand tissue could be an early signal of life-threatening cardiac amyloidosis.

An alternative to exercise: Chemical may lower BP without lifestyle changes

Beta hydroxybutyrate—a ketone body produced in the liver—could be key to regulating hypertension in heart patients who aren’t able to exercise, according to research out of the University of Toledo.

Catheter ablation safer than surgery for paroxysmal or early persistent AFib

Catheter ablation was associated with better arrhythmia-free survival and lower complication rates than surgical ablation in patients with paroxysmal or early-onset persistent atrial fibrillation (AFib), according to a small, randomized study published in Circulation: Arrhythmia and Electrophysiology.
