While the benefits of resistance training on musculoskeletal health are on daily display in any weightlifting room, the question of how much good all those sets and reps do for the heart has been open. Now comes an imaging-based answer from Germany, where researchers using MRI found measurable cardiac changes in a randomized group of novice male “gym rats” after they’d worked out regularly for around half a year.

Acute chest-pain patients imaged with coronary CT angiography (CCTA) are more likely to receive revascularization and invasive coronary interventions that don’t clearly improve outcomes than patients evaluated with standard functional tests such as stress EKG and stress echocardiography, according to a meta-analysis of randomized clinical trials.

Imaging techniques can be beneficial in identifying ischemic heart disease during minimally invasive autopsies, according to a study presented at RSNA 2017 in Chicago.

Former National Football League (NFL) players have significantly larger aortas than similarly aged men in the general population, potentially putting them at higher risk for aortic rupture or dissection, according to research presented Nov. 29 at RSNA 2017 and published online in Circulation: Cardiovascular Imaging.

Multidetector computed tomography (CT) could play a pivotal role in improving the outcomes of transcatheter aortic valve replacement (TAVR) procedures, research presented at the 103rd annual RSNA symposium suggests.

Technology from HeartFlow provides insights to help identify coronary plaques at risk of rupturing

A study of hemodynamic data from HeartFlow, Inc. may help predict which coronary plaques have the potential to rupture. Analyzing HeartFlow technology, the study was designed to predict the risk of developing acute coronary syndrome (ACS), a condition associated with sudden, reduced blood flow to the heart.

USPSTF releases draft research plan on screening for CVD risk and atrial fibrillation with electrocardiography

The U.S. Preventive Services Task Force (USPSTF) released a draft research plan on screening for cardiovascular disease risk and atrial fibrillation with electrocardiography. The plan is open for public comment until June 1 at 8:00 p.m. EST. The USPSTF will read and evaluate the comments and use them to develop a systematic review of the evidence.

Photoacoustic imaging gives researchers an inside look at arterial plaque

An international team of researchers from Purdue University in Indiana and the Shanghai Institute of Optics and Fine Mechanics in Shanghai, China, have developed a highly sensitive imaging probe capable of more accurately assessing impending risks to patients resulting from arterial plaques.

Cardiovascular MRI tops SPECT as predictor of future adverse cardiac events

Cardiovascular MRI is more effective than SPECT at predicting major adverse cardiovascular events in patients with suspected heart disease, according to results of a new study recently published in the Annals of Internal Medicine.

3D virtual heart helps identify potential defibrillator implant patients

Researchers from Johns Hopkins University have developed a non-invasive method to determine a patient’s risk of cardiac arrhythmia and the appropriateness of a defibrillator implant using a 3D virtual heart assessment tool, according to results of a study published online in the journal Nature Communications.

New imaging recommendations for prosthetic heart valve assessment

Recommendations for the assessment of prosthetic heart valves using multimodality imaging including echochardiography and cardiac CT have been published in European Heart Journal: Cardiovascular Imaging.

Streamlined algorithms spur update to heart failure evaluation guidelines

The American Society of Echocardiography (ASE) and the European Association of Cardiovascular Imaging (EACVI) have jointly released an update to recommendations for the evaluation of left ventricular diastolic function using echocardiography imaging. The update was recently published in the April issue of the Journal of the American Society of Echocardiography.

Study reveals high rate of questionable imaging in asymptomatic revascularization patients

A majority of Veterans Health Administration (VHA) patients who underwent carotid revascularization for asymptomatic carotid disease were diagnosed based on “uncertain” or “inappropriate” imaging, according to a study published in JAMA Internal Medicine

Image-guided stent retrievers speed treatment to improve stroke outcomes

Stent retrievers guided by radiography allow for faster treatment of ischemic stroke and improve patient outcomes, according to results of a new study published online April 19 in the journal Radiology.

Cath lab personnel experience more health problems than unexposed staff

Italian researchers have successfully linked the amount of time spent inside cardiac catheterization labs—and therefore the time spent exposed to potentially harmful radiation—with an increased prevalence in negative health conditions such as skin lesions, cataracts and hypertension, according to results published online in the journal Circulation: Cardiovascular Interventions.
