Heart attack warning as NHS doctor says symptoms could be 'silent'

People with the lung disease COPD have nearly twice the risk of suffering a heart attack, according to a new study of over 20,000 Swedes. Now researchers are warning about the increasing use of vaping among schoolchildren.

Heart attack warning as NHS doctor says symptoms could be 'silent'

Heart attacks are a medical emergency that requires immediate treatment, but the symptoms could be easily missed.

Link between heart attack severity and circadian rhythm unveiled

The molecular mechanism behind why heart attacks can vary in severity depending on the time of day has been uncovered, potentially paving the way for innovative treatments that align with the natural circadian rhythm.

Researchers uncover link between heart attack severity and circadian rhythm

The molecular mechanism behind why heart attacks can vary in severity depending on the time of day has been uncovered by researchers at UTHealth Houston, potentially paving the way for innovative treatments that align with the natural circadian rhythm.

BMAL1–HIF2A heterodimer modulates circadian variations of myocardial injury

Acute myocardial infarction is a leading cause of morbidity and mortality worldwide1. Clinical studies have shown that the severity of cardiac injury after myocardial infarction exhibits a circadian pattern, with larger infarcts and poorer outcomes in patients experiencing morning-onset events2–7. However, the molecular mechanisms underlying these diurnal variations remain unclear. Here we show that the core circadian transcription factor BMAL17…

New mechanical pump regenerates heart muscle at 6x the normal rate

When heart muscle gets damaged, the result is often permanent. Unlike other muscles in the body, the heart has long been believed to lack the ability to heal itself. But recent research suggests that under the right conditions, even adult heart muscle cells, called cardiomyocytes, can regenerate. This discovery could open up new ways to treat and possibly even cure heart failure in the future. A Glimmer of Regrowth in the Failing Heart The heart…
