PCI before TAVR? In older CAD patients, deferral may be the best approach
Patients with coronary artery disease and severe aortic stenosis often undergo PCI before TAVR. According to new data presented at ACC.26, however, deferring PCI is associated with comparable outcomes as well as a reduced bleeding risk.
Premature menopause linked to substantial long-term heart risks
Starting menopause before the age of 40 could increase a woman's lifetime risk of coronary heart disease by up to 40%.
Cold weather responsible for many more stroke and heart attack deaths than heat
While heat consistently gets more attention in terms of public health messaging, new data show just how dangerous the cold can be.
MRI findings detail how a 'leaky' barrier can damage the brain years after head injuries
New evidence suggests the BBB can remain compromised following a head injury, even years after it first occurred.
Single injection could help heal heart attack damage
Amplifying the body’s natural release of a specific hormone may reduce stress on the heart and limit long‑term damage after myocardial infarctions.

Saarland University adopting Sectra Education Portal to enhance medical learning

The German institution will have access to the portal for training radiology techs in a patient care setting.

Aycan and Enspectra partner for clinical trials on cellular imaging system

The VIO system visualizes and captures images at the cellular level for improved diagnostics.

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.

Focused ultrasound may alleviate pain without drugs, study finds

Researchers from Virginia Tech uncovered physiological changes from altering the way the brain perceives pain.

Artifacts from hair on X-rays shed light on health equity gap

Do radiologists see how the hair styles of Black and brown people impact imaging exams?

Microrobots guided by an MRI eradicate liver cancer

The technique was successful in a proof-of-concept animal study, but human trials are a long way off.

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.
