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.

ASNC, SNMMI release position statement, guidelines on myocardial perfusion PET

After reviewing the available literature, the societies said that rest-stress myocardial perfusion PET was a first-line preferred test for patients with known or suspected coronary artery disease who meet the criteria for stress imaging and are unable to complete the diagnostic level exercise stress imaging study.

Bigger hearts don’t necessarily signal a bigger problem

“Athlete’s heart” is a documented phenomenon in which the hearts of endurance athletes become enlarged in response to high levels of exercise. Aware of the condition, physicians are careful not to misdiagnose athletes with heart disease, which is a potential cause of an enlarged heart.

Human heart regeneration on the horizon

University of Houston researchers are developing strategies to help regenerate heart muscle cell formation. 

People with HIV at greater risk for developing heart disease, new research suggests

HIV puts individuals at higher risk for developing several chronic diseases, one of them being coronary artery disease (CAD). Medical professionals know this but haven’t been able to pinpoint the underlying reasons that contribute to the development of the disease. But new research delves into why and how CAD can develop. 

Study uses NASA technology for heart health tests

A new study underway at the University of Cincinnati Medical Center could give physicians a way to get a better understanding of patients’ cardiac health using technology developed by NASA, according to a statement by the university.

 
Two coronary CT image datasets shown obtainable during one short breath-hold

Researchers in Japan have demonstrated a way to modify a coronary CT technique such that it significantly cuts the time patients have to hold their breath while being scanned both with and without contrast, according to a study published online July 14 in Academic Radiology. 

Tomosynthesis beats chest x-ray at guiding decision-making around pulmonary nodules

Spots on the lung are better detected and managed by digital chest tomosynthesis than by imaging with conventional chest radiography, including when the latter is augmented by dual-energy (DE) technology—and regardless of the lack of deep, chest-specific experience in the interpreting radiologist. 

More precise MRI technique works better for patients with dilated cardiomyopathy

A previously unused type of MRI scan can work to measure heart conditions in patients with dilated cardiomyopathy, according to a new study published in Radiology.

 
New study reveals why patients quit antiplatelet medication

Although patients stop taking their antiplatelet medication for a variety of reasons, new research suggests that better education will help ensure they take it.
