siRNA therapy shows promise for reducing genetic heart disease risk

In phase 1 trials, an experimental siRNA therapy has shown promise for reducing levels of a lipoprotein associated with a higher risk of premature heart disease. The treatment could help fight a form of the disease that can’t currently be treated throu… Continue reading siRNA therapy shows promise for reducing genetic heart disease risk→

Heart cells’ 24-hour clock may explain prevalence of morning heart attacks

New research has discovered a distinct circadian mechanism within heart cells that influences how cardiac activity shifts across 24-hour periods. The findings offer clues to why shift workers are at higher risk of heart problems.Continue ReadingCategor… Continue reading Heart cells’ 24-hour clock may explain prevalence of morning heart attacks→

Real-world tests show life-saving potential of defibrillator drones

Drones may prove to be a more expedient means of delivering many items, but a number of research projects have demonstrated that dropping defibrillators off to heart attack victims could have life-saving consequences. A new study from a Swedish team of… Continue reading Real-world tests show life-saving potential of defibrillator drones→

Noisy nanoparticles sound plaque alarm before heart attack or stroke

Cardiovascular diseases are the leading cause of death worldwide, but numbers could be reduced with better early warning systems. A new study has outlined just such a system, using nanoparticles that make atherosclerotic plaques emit ultrasound waves.C… Continue reading Noisy nanoparticles sound plaque alarm before heart attack or stroke→

Wearable ultrasound patch could warn of cardiovascular problems

It goes without saying that the earlier someone can be warned of an impending heart attack or stroke, the better. A new skin patch could provide such warnings, by sending ultrasound pulses into the wearer’s body.Continue ReadingCategory: Medical, Scien… Continue reading Wearable ultrasound patch could warn of cardiovascular problems→

Protein in deadly spider venom blocks “death signal” after heart attack

As unlikely as it may seem, the venom of the deadly funnel web spider could prove a valuable source of a number of life-saving medicines, including drugs that kill skin cancer and reduce brain damage in stroke victims. Adding to these possibilities is … Continue reading Protein in deadly spider venom blocks “death signal” after heart attack→

Stem cells “reprogrammed” by diabetes could increase heart attack risk

Diabetes has a long list of run-on health effects, and one of them is an increased risk of cardiovascular disease. Now, scientists at Oxford have uncovered a mechanism behind that, finding high blood sugar levels “reprogram” stem cells so the white blo… Continue reading Stem cells “reprogrammed” by diabetes could increase heart attack risk→

Exosome spray may be better able to heal damaged hearts

After someone has suffered a heart attack, non-beating scar tissue grows back in place of the damaged cardiac tissue, leaving the heart permanently weakened. A newly developed spray-on medication, however, may someday help change that.Continue ReadingC… Continue reading Exosome spray may be better able to heal damaged hearts→
