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.

The addition of perivascular fat attenuation to routine coronary computed tomography angiography (CTA) improves risk stratification in heart patients, according to research presented at the European Society of Cardiology (ESC)’s annual symposium in Munich, surpassing current prognostic models to re-classify and predict cardiac deaths with more accuracy.

Patients with stable chest pain who were evaluated with coronary CT angiography (CTA) were significantly less likely to experience a heart attack or die from coronary heart disease (CHD) within five years compared to individuals who received standard testing, researchers reported in the New England Journal of Medicine.

Intravascular ultrasound may help identify patients who will benefit most from distal protection during percutaneous coronary intervention (PCI), according to a new study published in JACC: Cardiovascular Interventions.

The Avert system successfully reduced contrast media volume but failed to trim the risk of acute kidney injury (AKI) following coronary angiography, according to a trial published in JACC: Cardiovascular Interventions.

Patients with valvular heart disease were significantly less likely to receive transthoracic echocardiograms (TTEs) within guideline-recommended timeframes if they were women, black, older or used Medicaid insurance, according to a single-center study published in JACC: Cardiovascular Imaging.

More frequent chest x-ray screenings of children with epicardial pacemakers may help identify those at risk of coronary artery compression, according to the authors of a study published online Aug. 13 in HeartRhythm.

A machine learning algorithm derived from thoracic phase signals can identify obstructive coronary artery disease (CAD) with the same accuracy as existing functional tests, according to a study published Aug. 8 in PLOS One. The signals can be collected in about three minutes and don’t require the patient to exercise or be exposed to radiation, contrast media or pharmacological stress.

Coronary microvascular dysfunction (CMD) identified with cardiac stress PET testing was a better predictor of adverse events among obese patients than body mass index (BMI) and other traditional risk factors, researchers reported in the Journal of the American College of Cardiology.

Instantaneous wave-free ratio (iFR) and fractional flow reserve (FFR) were equally safe in deferring patients from coronary revascularization, according to a pooled analysis of two randomized trials published Aug. 6 in JACC: Cardiovascular Interventions.

In a single-center study of smokers with heart failure, those who also had emphysema identified by CT were twice as likely to be rehospitalized for heart failure in the following two years.

A group of researchers from a Veterans Affairs health system in California shared their experience with limited left ventricular echocardiography, something they believe could reduce the cost and time required for testing in select patients.
