High cholesterol levels are a common and potentially deadly health problem, but a new drug could help more people manage the condition. An experimental pill has been shown to reduce levels of “bad” cholesterol by 60% in a phase 2 clinical trial.Continu… Continue reading Oral pill cuts bad cholesterol by 60% in phase 2 clinical trial
The heart has long been called our “ticker.” Now, a new study shows why that might be the case even more than we previously imagined. Researchers at Cornell University have demonstrated that our perception of time shifts with the length of our heartbea… Continue reading Our heartbeats cause “wrinkles in time” says new study
Before operating on someone, it would be very helpful if cardiac surgeons could examine a physical model of that specific individual’s heart. Well, they should soon be able to do so – and the model will actually pump liquid, just like the patient’s rea… Continue reading Liquid-pumping heart replicas could lead to better cardiac treatments
Organ transplants can save lives, but unfortunately organs don’t last long in storage. Now scientists have demonstrated that an existing drug can reprogram donor hearts to last much longer outside the body, and reduce their risk of failure after transp… Continue reading Drug reprograms donor hearts for longer storage and safer transplants
Researchers studying the hearts of healthy centenarians have homed in on a specific genetic mutation that seems to play a crucial role in maintaining cardiovascular functions in old age. Across a series of lab and animal experiments the researchers dem… Continue reading Unique gene mutation in superagers could rewind heart age by a decade
A new study is offering more evidence expensive vitamin supplements may be a waste of money, finding six common heart-health formulations are ineffective at reducing cholesterol levels or markers of inflammation. Cardiovascular experts say patients sho… Continue reading Heart-health supplements ineffective at reducing bad cholesterol
Ordinarily, pacemakers correct irregular heartbeats by delivering an electric shock to the entire heart – which can be painful. An experimental new one takes a different approach, and it does so by encompassing the heart with light-emitting “petals.”Co… Continue reading Flower-like pacemaker uses light for pain-free defibrillation
Smartphones are beginning to have a real influence on the way we manage our day-to-day health, and one area they may have a significant impact is in monitoring our hearts. A new study has demonstrated that an app designed to turn smartphones into electronic stethoscopes can capture reliable, quality recordings of user heartbeats across the population, which doctors can then use to remotely monitor progression of heart conditions.

Soft tissues don’t fossilize well, so most of the time scientists have to infer organ anatomy from just bones. But an unexpected treasure trove of new information has been discovered in Australia, with a 380-million-year-old fish fossil preserving the oldest heart ever found.

Scientists have demonstrated a new system that can restore crucial molecular and cellular functions in pigs one hour after death. Experiments showed that some tissue damage from loss of oxygen can be reversed, which could widen the organ transplantatio… Continue reading Scientists restore vital cellular functions to pigs one hour after death
