Poor mid-life heart health linked to dementia in later years

Posted on by

A new study has found healthy subjects in their 50s with subclinical signs of heart disease also displayed impaired metabolism in parts of the brain associated with Alzheimer's disease

A compelling new study, led by a team of Spanish researchers, is suggesting cardiovascular disease in mid-life is linked to neurodegeneration and cognitive decline in senior years. The research found subjects in their 50s with mild hypertension displayed evidence of impaired brain metabolism in areas associated with Alzheimer’s and dementia.

Artificial aorta takes pressure off the heart to reduce transplants

Posted on by

When the heart is injured it can’t repair itself, meaning that heart failure often requires a transplant of the whole organ. But now, scientists at EPFL have developed an artificial aorta that can help pump blood, taking some of the pressure off the he… Continue reading Artificial aorta takes pressure off the heart to reduce transplants→

Swine of the Times: Pig-to-Human Organ Transplants on Track for 2021

The results of a new study in which fruit flies were flown to the International Space Station (ISS) and back could help develop treatments designed to keep astronauts’ hearts healthy on long-haul missions to Mars.Continue ReadingCategory: Space, Scienc… Continue reading Spacefaring flies shed light on heart defect caused by microgravity→

Life-size model heart 3D-printed out of cardiac tissue-like material

Posted on by

If you were planning to perform open-heart surgery on someone, it would definitely help if you could first do a “dry run” on an exact replica of their heart. Doing so may soon be possible, thanks to a recent advance in 3D printing technology.Continue R… Continue reading Life-size model heart 3D-printed out of cardiac tissue-like material→

Experimental drug halves cholesterol levels in phase 2 clinical trials

Posted on by

Scientists are reporting promising results from a phase 2 clinical trial of a cholesterol-reducing drug called evinacumab. The study reports that in patients with extremely high cholesterol, the drug was able to reduce levels by about half, compared to… Continue reading Experimental drug halves cholesterol levels in phase 2 clinical trials→

Self-powered patch monitors and treats damaged hearts

Posted on by

Over the years we’ve looked at many implantable patches that can be used to treat damaged hearts, but a new example developed at the University of Houston is claimed to take these into new territory. Described as the first of its kind, the rubbery patc… Continue reading Self-powered patch monitors and treats damaged hearts→

Scientists knit new artery grafts out of collagen and synthetic fibers

Posted on by

Heart attack patients often need replacements for damaged or blocked sections of coronary arteries, which are usually taken from their own leg veins. But in a new proof-of-concept study, scientists knitted a prototype graft out of hybrid synthetic and … Continue reading Scientists knit new artery grafts out of collagen and synthetic fibers→

Depression detectable through heart rate fluctuations, small study finds

Posted on by

New research, presented at the European College of Neuropsychopharmacology’s Virtual Congress, has shown depression can be detected by monitoring fluctuations in a person’s heart rate over a 24-hour period. The small, proof-of-concept study certainly n… Continue reading Depression detectable through heart rate fluctuations, small study finds→

Spit test promises to diagnose heart attacks in just 10 minutes

Posted on by

New preliminary research is suggesting a simple saliva test can detect the presence of a protein biomarker known to signal the occurrence of a heart attack in just 10 minutes. If this prototype test is validated in future studies it could dramatically … Continue reading Spit test promises to diagnose heart attacks in just 10 minutes→
