Cardiovascular Imaging

At Brigham and Women’s Hospital, like many hospitals and medical centers across the country, cardiac PET is emerging as the go-to imaging modality for a growing list of clinical scenarios.

Experts recently offered a blueprint to make the choice easier when it comes to using cardiac PET to assess coronary artery disease, myocardial perfusion, viability, and ventricular function.

A randomized trial found that patients with suspected coronary heart disease who underwent cardiovascular magnetic resonance (CMR)–guided care had a significantly lower probability of unnecessary angiography within 12 months compared with patients who received National Institute for Health and Care Excellence (NICE) guidelines–directed care. The difference was not statistically different between CMR-guided care and myocardial perfusion scintigraphy (MPS)–guided care.

Researchers have used PET/CT imaging to link stress-related amygdala activation in the brain with arterial inflammation and an increased risk of eventual cardiovascular disease events, according to results of a study presented today at ACC.16 in Chicago.

A systematic comparative effectiveness review of noninvasive testing for coronary artery disease found there was no significant difference in MI or all-cause mortality between testing strategies across settings and pretest risk groups. The Agency for Healthcare Research and Quality (AHRQ) conducted the review and released the report on March 29.

Although nearly one-fifth of adults with acute stroke syndromes had rapid neurological improvement before entering the hospital, 47 percent of that group was not discharged to their homes, according to a post-hoc analysis of a randomized trial.

Inpatient echocardiography is on the rise and, with it, questions about potential overutilization. A new study suggests that, on the contrary, during critical cardiovascular hospitalizations, echo may not get tapped enough.

Merge Healthcare claimed four awards—including the distinction of Category Leader in cardiology—in the Best in KLAS 2015/2016 honors.

The American College of Cardiology (ACC) and American College of Radiology (ACR) released guidelines on Jan. 22 regarding the appropriate use of imaging for patients who come to the emergency department with chest pain.

An analysis of Medicare Part B databases found that the use of radionuclide myocardial perfusion imaging (MPI), stress echocardiography and coronary CT angiography for suspected coronary artery disease declined in recent years. Although studies have shown the value of coronary CT angiography, it is still being used much less frequently than the other two noninvasive imaging techniques.

For patients with chest pain and no known coronary artery disease, an evaluation strategy based on fractional flow reserve estimated using CT (FFRCT) led to reduced costs within 90 days and less resource utilization compared with an invasive coronary angiography evaluation strategy.
