Cardiac MRI can accurately diagnose pulmonary hypertension (PH) without the invasiveness of right-sided heart catheterization (RHC), suggests a new study published in Radiology.

A simple score containing four MRI markers of cerebral small vessel disease (CSVD) is associated with stroke, dementia and mortality among older adults, according to an analysis of the population-based Rotterdam Study published Oct. 24 in Stroke.

Coronary artery calcium (CAC) is predictive of all-cause and cardiovascular mortality across all racial and ethnic groups, according to a study published in the Journal of the American Heart Association—but the risk of those outcomes is significantly higher across all CAC scores for black and Hispanic patients than for whites and Asians.

Transcranial duplex sonography (TCD) can assess middle cerebral artery blood flow and provide prognostic information for stroke patients after thrombectomy for large vessel occlusions, suggests a report published Oct. 15 in Stroke.

Right ventricular (RV) strain analysis could be a useful addition to existing methods of risk assessment in patients with acute decompensated heart failure (ADHF), according to recent research that identified RV longitudinal strain from the free wall (RV-fwLS) as an independent predictor of cardiac events in the demographic.

Avinger announced on Oct. 18 its Pantheris SV atherectomy device has gained CE mark approval, allowing it to be sold commercially in Europe. The system extends the plaque-removing technique for peripheral artery disease to smaller vessels with diameters between 2 and 4 millimeters.

The proportion of part-time cardiologists is declining at a time when one would expect health systems to be doing everything they can to keep competent physicians on board, according to MedAxiom’s 2018 Cardiovascular Provider Compensation & Production Survey.

People with unrecognized myocardial infarction carry a lower short-term risk of death but an equal 10-year risk of mortality compared to those with clinically diagnosed heart attacks, according to an analysis of the ICELAND MI study published in JAMA Cardiology.

MRI measurements of carotid wall thickness improve predictions of cardiovascular disease risk more than a commonly used ultrasound-based test, according to research published Oct. 9 in Radiology.

Asymptomatic patients with severe aortic stenosis are at greater risk of all-cause and cardiovascular mortality if they have higher peak aortic jet velocities or left ventricular ejection fractions (LVEFs) below 60 percent, researchers reported Oct. 3 in JAMA Cardiology.

Women who suffer from peripartum cardiomyopathy (PPCM) will likely be clinically asymptomatic seven years after they give birth, according to research published in the Journal of the American Heart Association Oct. 3—but it’s also likely they’ll develop enduring diastolic dysfunction and reduced exercise capacity in the same window.

Fractional flow reserve (FFR) can be closely approximated using conventional coronary angiography and propriety software, according to the FAST-FFR study published online in Circulation. The findings offer a potential route for more patients with suspected coronary artery disease to receive functional assessment of lesions without the need for a guidewire or hyperemic agents.
