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.

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

The Reprieve System using intelligent software and automation to manage diuretic dosing and fluid replacement for patients with acute decompensated heart failure (ADHF).

Reprieve Cardiovascular emerged from stealth mode this week with sizable financial backing and some big name board members to advance development for its intelligent, automated diuretic and fluid management system for heart failure.

An Illinois appellate judge upheld a pervious trial victory that cleared and central Illinois cardiologist Amit Dande, MD, and Prairie Cardiovascular Consults LLP of alleged misdiagnosis of the severity of a patient's heart condition that led to his death prior to a schedule percutaneous coronary intervention (PCI).

A judge upheld a previous trial victory that cleared Prairie Cardiovascular Consults of alleged mishandling of a patient and not fully understanding the severity of the heart condition prior to their death.

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.

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

Several key trends were evident at the Radiological Society of North America 2024 meeting, including new CT and MR technology and evolving adoption of artificial intelligence.

Ron Blankstein, MD, professor of radiology, Harvard Medical School, explains the use of artificial intelligence to detect heart disease in non-cardiac CT exams.

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