Cardiovascular Imaging

Assessment of abdominal aortic calcification using computed tomography (CT) is a highly effective predictor of future heart attack and CVD risk, according to research published in Radiology Oct. 2—more effective even than the Framingham risk score, which has been relied upon for more than two decades.

With additional testing for nonobstructive coronary artery disease (CAD), researchers effectively diagnosed microvascular and/or vasospastic angina—as well as non-cardiac related chest pain—and used that information to guide therapy decisions and significantly improve angina and quality-of-life outcomes.

Intravascular ultrasound (IVUS)-guided stent implantation offers improved clinical outcomes for heart patients over a traditional angiography-guided approach, researchers from China reported at this week’s Transcatheter Cardiovascular Therapeutics (TCT) meeting in San Diego, California.

Researchers have developed cardiology’s first pipeline for automated echocardiogram interpretation—an innovation that could cut healthcare costs while expanding care to underserved communities, according to a study published online this week in Circulation.

Photoplethysmography—a noninvasive imaging technique that allows clinicians to measure a patient’s pulse wave velocity as blood moves away from their heart—has for the first time linked alterations in the carotid system to changes in physical movement, according to research out of ITMO University in Saint Petersburg, Russia.

When North Colorado Medical Center in Greeley set out to build a new hybrid OR equipped with robotic angiography, they had no idea the project would set a new bar for project planning and execution across the health system, bring “exponential improvements” in image quality and “exponential reductions” in radiation dose and contrast media, or that they’d finish the project almost a month early without a single change order and $600,000 under budget. Teamwork, meticulous planning and virtual reality-guidance played an essential role in refining and perfecting this image-guided surgery suite even before a pen was put to paper.

Visual estimations of the completeness of revascularization failed to predict subsequent cardiovascular events for patients with acute coronary syndromes (ACS) who underwent stenting guided by fractional flow reserve (FFR), researchers reported in the Journal of the American College of Cardiology.

Scientists have developed a wearable ultrasound device to measure central blood pressure (BP). It performed as well as a current noninvasive technique upon testing, according to a press release.

Millimeter wave body scanners—standard security measures at airports, train stations and public buildings since the 2000s—are completely safe for heart patients with implantable devices, German researchers reported at last month’s ESC Congress.

Heart attack and stroke patients could minimize their risk of a second infarction by consuming apocynin, an antioxidant close in chemical structure to vanilla, according to research out of Portland, Oregon.

A prevalence of left atrial fibrosis in endurance athletes could explain their increased risk for arrhythmias like atrial fibrillation (AFib), according to data presented this week at the European Society of Cardiology (ESC) Congress in Munich.

A simplified cardiac magnetic resonance (CMR) protocol using a contrast agent allowed clinicians in Peru to diagnose heart ailments more quickly and cheaply, a new study found. The results, published online Aug. 29 in the Journal of the American Heart Association, highlight a potential pathway to realizing the benefits of CMR in developing nations.
