UW researchers engineer stem cells that do not generate dangerous arrhythmias

Researchers at the University of Washington School of Medicine in Seattle have engineered stem cells that do not generate dangerous arrhythmias, a complication that has to date thwarted efforts to develop stem-cell therapies for injured hearts.

Research uncovers the root cause of adverse health effects from circadian rhythm disruption

New research at the University of Massachusetts Amherst zeroes in on the root cause of adverse health effects from disruption of the body's circadian rhythms, which typically occurs from jet lag and rotating work shifts.

New imaging tool creates real-time, 3D images and maps of contractions during labor

Researchers funded by the National Institutes of Health have developed a new imaging tool, called electromyometrial imaging (EMMI), to create real-time, three-dimensional images and maps of contractions during labor.

Using tissue-embedded nanoelectronic devices to monitor the functional maturation of cardiomyocytes

Research in animal models has demonstrated that stem-cell derived heart tissues have promising potential for therapeutic applications to treat cardiac disease. But before such therapies are viable and safe for use in humans, scientists must first precisely understand on the cellular and molecular levels which factors are necessary for implanted stem-cell derived heart cells to properly grow and integrate in three dimensions within surrounding tissue.

Researchers optically evoke tachycardia enhanced anxiety-like behaviour

In a recent study published in the journal Nature, researchers devised a non-invasive optogenetic and wearable cardiac pacemaker for accurate and specific control of cardiac rhythm for ≤900 beats per minute (bpm), enabled by micro-light-emitting display (LED) harness and systemic channelrhodopsin delivery.

Initial benefit of TAVR remains consistent over the first three years among patients at low surgical risk

The number of deaths and disabling strokes among patients at low surgical risk who were treated with transcatheter aortic valve replacement (TAVR) remained lower at three years, but not significantly lower, following the TAVR procedure compared with patients who received conventional surgical aortic valve replacement (SAVR), according to new data being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

Certain wearable gadgets could pose serious risks for people with cardiac implantable electronic devices

In recent years, wearable devices such as smartwatches and rings, as well as smart scales, have become ubiquitous – "must-haves" for the health conscious to self-monitor heart rate, blood pressure, and other vital signs.

Researchers report two unusual COVID-19-related arrhythmic cases in children

Researchers explored the association between cardiac arrhythmias in children and COVID-19 infection.

Researchers investigate whether the perception of time changes with age

Researchers at Eötvös Loránd University have investigated whether the perception of time changes with age, and if so, how, and why we perceive the passage of time differently.

Understanding more about heart rhythm disorders

Heart rhythm disorders like atrial fibrillation and sudden cardiac arrest have made headlines in recent months, prompting many to learn more about how the heart beats.

Research uncovers a new way to boost the effectiveness of RNA therapies

Investigators from the Smidt Heart Institute at Cedars-Sinai have identified how biological pacemaker cells-;cells that control your heartbeat-;can "fight back" against therapies to biologically correct abnormal heartbeat rates.

Wireless, battery-free pacemaker could make life easier for heart disease patients

Atrial fibrillation – a form of irregular heartbeat, or arrhythmia – leads to more than 454,000 hospitalizations and nearly 160,000 deaths in the United States each year. Globally, it is estimated that approximately 60 million people are affected by the condition.

UMass Amherst genetic research provides a new model for investigating diseases related to circadian rhythm disruptions

University of Massachusetts Amherst research into genetic mutations that affect circadian rhythms offers new insight into the rest-wake cycle and provides a new model for investigating human disease and ultimately developing medical treatments.

Minimally invasive procedure enables patients to be out of the hospital within a few days

Minimally invasive, catheter-based transcatheter aortic valve replacement (TAVR) has revolutionized treatment of aortic stenosis (AS), and both American and European guidelines have approved its use. However, there is a perception that TAVR is more expensive than surgical aortic valve replacement (SAVR). A budget impact analysis comparing the two options now shows that TAVR is an affordable and effective strategy for the treatment of AS. The study appears in the Canadian Journal of Cardiology, published by Elsevier.

Healthy people over 65 years of age recommended to get a heart check-up before non-cardiac surgery

A heart check-up is recommended in even apparently healthy people over 65 years of age before intermediate- or high-risk non-cardiac surgery, according to European Society of Cardiology (ESC) Guidelines on cardiovascular assessment and management of patients undergoing non-cardiac surgery published online today in European Heart Journal.

Neurons show rhythmic activity at different frequencies in the desynchronized state

In the 17th century, the Dutch scientist Christiaan Huygens hanged two of his recently invented pendulum clocks on a wooden beam and observed that as time passed, the clocks aligned their beats.
