What CV research looks like in space

Researchers on the International Space Station are leveraging the microgravity conditions within the ISS U.S. National Laboratory to study heart cells in ways we can’t on the ground.

Mobile stroke units get patients to hospital faster than ambulances

Transport to the hospital via mobile stroke unit—as opposed to standard transit in an ambulance—saved stroke victims 10 minutes and up to 270 million neurons in a study out of the University of Texas Health Science Center at Houston.

Motivation key to post-PCI recovery among women

The results of a Journal of Cardiovascular Nursing study suggest motivation is the key driver of adherence to secondary prevention measures among women who have CHD and have undergone PCI.

Plant-based diets once again linked to lower CVD risk

People who ate the most plant-based foods in a recent Journal of the American Heart Association study were 32% less likely than their counterparts to die from heart disease later down the line.

Endovascular-first approach boosts amputation-free survival in patients with critical limb ischemia

Patients with critical limb ischemia might be better off if they opt for endovascular-first treatment over an open surgical bypass, a Circulation: Cardiovascular Quality and Outcomes study suggests.

Surgery fails to improve survival in those with severe TR

Surgery doesn’t improve survival in patients with isolated severe tricuspid regurgitation, researchers have found.

Warm perfusion preserves donor hearts for up to 10 hours

The director of Duke University’s heart transplant program is promoting warm perfusion—a technique that preserves organs more effectively than a traditional cooling box—as a means of expanding the CV donor pool in the U.S.

Update: FDA acknowledges late mortality signal with paclitaxel devices

The FDA issued an advisory August 7 updating healthcare providers and the public on its stance regarding the long-term safety of paclitaxel-coated and -eluting devices, sharing that its expert panel had indeed identified a late mortality signal associated with the devices.

Around the web

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.
