Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

Wearable activity trackers show promise in detecting early signals of disease

Fitbit, Apple Watch or Oura ring, wearable technology is in high demand among the health conscious. But beyond measuring heart rates and blood pressure, could fitness trackers be used to test for and effectively screen for disease?

Genetic variants linked to heart rhythm disturbances in Wolff-Parkinson-White Syndrome

Study by scientists at deCODE genetics/Amgen and collaborators in Denmark and the USA, on the genetics of accessory conduction pathways in the heart (Wolff-Parkinson-White syndrome), reveals that accessory pathways can cause rhythm disturbances, characterized by an overly fast heartbeat, which can be life-threatening.

Interrupting beta-blockers after myocardial infarction shows no advantage

The cardiovascular safety of interrupting beta-blocker could not be shown in comparison to continuation in patients with a history of myocardial infarction (MI) and there was no benefit to the patients' quality of life, according to late-breaking research presented in a Hot Line session today at ESC Congress 2024.

Recreational drug users three times more likely to experience repeat cardiovascular events

New research presented at this year's ESC Congress 2024 in London, UK (30 Aug – 2 Sept) shows that, among patients admitted to the intensive cardiac care unit (ICCU), those with a recent history of recreational drug use are three times more likely than those with no history to experience a repeat serious cardiovascular event within one year.

Innovative AI tool targets missing data to enhance sepsis risk predictions

A proposed artificial intelligence tool to support clinician decision-making about hospital patients at risk for sepsis has an unusual feature: accounting for its lack of certainty and suggesting what demographic data, vital signs and lab test results it needs to improve its predictive performance.

Exploring the impact of thyroid hormone on brain function

Thyroid hormone plays a key role in regulating a range of physiologic functions, including metabolism, temperature, heart rate, and growth. It accomplishes this impressive array of activities by interacting with almost every organ system in the body. Yet despite a long history of research on how thyroid hormone influences different organs, its effects on arguably the most crucial organ -; the brain -; have remained shrouded in mystery.

FDA-approved drug could revolutionize organ transplantation

Researchers at the Wyss Institute for Biologically Inspired Engineering at Harvard University report that they were able to successfully put tadpoles of Xenopus laevis frogs into a hibernation-like torpor state using donepezil (DNP), a drug approved by the FDA to treat Alzheimer's. The team had previously used another drug, SNC80, to achieve similar results in tadpoles and enhance the survival of whole mammalian hearts for transplants, but SNC80 is not approved for clinical use in humans because it can cause seizures. By contrast, DNP is already being used in the clinic, meaning it potentially could be rapidly repurposed for use in emergency situations to prevent irreversible organ injury while a person is being transported to a hospital.

Long COVID symptoms may stem from low cortisol and altered brain immune response

Proteins left behind by COVID-19 long after initial infection can cause cortisol levels in the brain to plummet, inflame the nervous system and prime its immune cells to hyper-react when another stressor arises, according to new animal research by University of Colorado Boulder scientists.
