Using coronary microvascular dysfunction (CMD) measurement identified with cardiac stress PET was more accurate at predicting adverse events in obese patients compared to measuring body mass index (BMI), according to a recent Journal of the American College of Cardiology study.
Researchers from Boston Children’s Hospital and Harvard Medical School recommend stricter chest x-ray screenings of children fitted with epicardial pacemakers to detect those at risk of coronary artery compression, according to a study published online Aug. 13 in HeartRhythm.
A 20-year study published in the New England Journal of Medicine on Aug. 9 compiled cardiovascular screening exams from more than 11,000 adolescent soccer players in the U.K. It found that routine cardiac imaging tests prevented an insufficient amount of heart-related deaths from physical activity.
A group of California researchers believes a limited transthoracic echocardiogram (TTE) that solely evaluates the left ventricle could be more efficient and cost-effective in certain patients compared to whole echocardiography.
A team of international scientists developed a new non-invasive MRI-based early warning system that may alert physicians about approaching heart attacks in patients and identify those at high risk.
Optical coherence tomography (OCT) offers superior detection of coronary vascular changes compared to angiography in pediatric heart transplant recipients. The technique can be used to improve the medical management in this population.
Quantifying myocardial blood flow (MBF) with CT perfusion (CTP) imaging can accurately predict major adverse cardiac events (MACEs). It also showed improved risk stratification in stenosis patients when paired with coronary CT angiography (CTA), according to a recent JACC: Cardiovascular Imaging study.
Quantitative flow ratio (QFR) outperformed coronary angiography in calculating fractional flow reserve (FFR), a measurement key to determining heart blockages, according to a study in the Journal of the American Heart Association.
Myocardial delayed enhancement (MDE) CT rivaled late gadolinium enhanced (LGE) MRI in the detection and classification of myocardial scar in patients with heart failure, according to a recent Radiology study. The results may help identify features of chronic heart failure.
Patients with retrievable inferior vena cava (IVC) filters used to prevent venous thromboembolisms face increased complication risks the longer their device remains in the body. Researchers created an informatics tool to address the issue.
Patients with stable coronary artery disease (CAD) monitored with either cardiac MR (CMR) or angiography demonstrated no difference in impact rates over three years, according to a recent JACC: Cardiovascular Imaging study.
In those tested for coronary artery disease, research published July 3 in Radiology suggests that cardiac hybrid imaging with CT imaging and nuclear stress testing may be an effective predictor of heart attack risk and other adverse cardiac events.
A majority of cardiovascular implantable electronic devices (CIEDs) in the U.S. are still MR-nonconditional, but a pair of neurologists believe hospitals need to assess their institutional policy to ensure patients have access to MRIs when needed.
4D flow CT produced similar intracardiac blood flow patterns compared to the current reference standard obtained with 4D MRI, according to recent research in Radiology.
A deep-learning software that can automatically calculate left ventricular ejection fraction (LVEF) with less variability than a cardiologist recently received approval from the U.S. Food and Drug Administration (FDA).

Coronary computed tomography angiography (CTA) is the current go-to for triaging chest pain patients in the emergency department (ED), but a recent study found the often-overlooked stress echocardiography (SE) may actually be safer and provide patients with a better overall experience.
