Ultra-processed foods linked to 32 adverse health outcomes, including CVD-related death and diabetes

Data from nearly 9.9 million participants were included in the team’s final analysis. The group emphasized the important role governments can play in trying to reverse the world's reliance on these products.

Left, the FIRE1 heart failure remote monitoring device that gets implanted into the IVC to measure fluid volume status. Right, the external belt monitoring device worn by the patient that can alert clinicians about status changes so interventions can be done before a patient requires a hospital admission. 

Early feasibility study for implantable heart failure monitor moves forward 

Startup vendor FIRE1 completed patient enrollment in its U.S. early feasibility study for a heart failure remote monitoring device that directly measures fluid volume inside the IVC.

Using the Sentinel cerebral protection device during valve-in-valve TAVR is associated with significant clinical improvements.

Cerebral protection devices during valve-in-valve TAVR: Cleveland Clinic cardiologists identify key benefits

Cerebral protection devices, designed to limit the risk of stroke during transcatheter aortic valve replacement, may be especially helpful when patients undergo valve-in-valve TAVR.

Multiple factors can interfere with pulse oximetry accuracy including skin pigmentation. Multiple studies have shown the inaccuracy of current pulse oximeters in patients with darker skin tones than whites, often over estimating their oxygenation when in fact they are hypoxic.

Inaccurate pulse oximeter readings impact Black heart failure patients and FDA plans to address this

Black patients are already less likely to receive LVADs or transplants compared to whites, and these inaccurate readings can further widen the disparities.

Examples of photon-counting coronary angiography showing how clarity improves as the thickness of the image is reduced. Top: 60-year-old female, with noncalcified plaque (arrowheads) and coronary stenosis (inset images). The reduced section thickness did not affect assessment in this patient. Bottom: 56-year-old female with calcified plaque (arrowheads) and coronary stenosis. The reduced section thickness leads to less calcium blooming and therefore a less severe percentage of stenosis.

Coronary artery disease classification improved with photon-counting CT

After a photon-counting CT, 54% of patients had their coronary artery disease classification downgraded.

Anticoagulants after TAVR: 5-year survival data favor DOACs over VKAs

However, that one finding does not tell the whole story. Researchers also found that DOACs may increase a TAVR patient's risk of a disabling stroke.

Michael Garshick, MD, director of the cardio-rheumatology program, cardiologist and assistant professor, Ronald O. Perelman Department of Dermatology, NYU Grossman School of Medicine, explains the role of inflammation in coronary disease development and how this risk factor can be detected and treated.

Targeting coronary inflammation helps cardiologists provide better care

Michael Garshick, MD, examines the role of inflammation in coronary disease development, detailing how this risk factor can be detected and treated.

Eleven medical societies have signed on to a consensus statement aimed at standardizing imaging for suspected cardiovascular infections.

Kate Hanneman, MD, explains why many vendors and hospitals want to lower radiology's impact on the environment. "Taking steps to reduce the carbon footprint in healthcare isn’t just an opportunity," she said. "It’s also a responsibility."
