by Catherine S. Williams, American Heart Association Credit: Pixabay/CC0 Public Domain Chest pain, heart palpitations, shortness of breath, lightheadedness, nausea: Are you having a heart attack or a panic attack? Doctors and psychologists agree you shouldn’t take a chance on it not being a heart attack. That’s because the symptoms of a heart attack and...
by Michael Morrison, Massachusetts General Hospital Summary of findings. Credit: Nature Cardiovascular Research (2022). DOI: 10.1038/s44161-022-00094-w Patients with heart disease are at risk of experiencing a potentially lethal “electrical storm” involving recurrent episodes of a type of irregular heartbeat called ventricular tachycardia (VT). Electric shock therapy is used to treat VT following a heart attack, but unfortunately,...
Anyone who has suffered from jet lag or struggled after turning the clock forward or back an hour for daylight saving time knows all about what researchers call your biological clock, or circadian rhythm – the “master pacemaker” that synchronizes how your body responds to the passing of one day to the next. This “clock” is...
by University of Gothenburg Cumulative incidences for patients with primary hyperparathyroidism (pHPT) and control individuals. The cumulative incidence of events for untreated pHPT and control groups was estimated using 1-minus Kaplan-Meier estimate of the corresponding survival function and presented with 95% CIs (indicated by shaded areas).

EUROPEAN SOCIETY OF HUMAN GENETICS Vienna, Austria: Combining information about the pattern of blood vessels in the retina with genetic data can enable accurate prediction of an individual’s risk of coronary artery disease (CAD) and its potentially fatal outcome, myocardial infarction (MI), commonly known as a heart attack. The discovery could lead to a simple screening...
by University of Montreal Graphical abstract. Credit: Circulation Research (2022). DOI: 10.1161/circresaha.121.319929 Heart attacks are damaging, and the severity depends on how long blood flow has been interrupted; when temporarily deprived of oxygen, heart cells die. In addition, the heart can’t rebuild its own tissue, leading to its failure, the main cause of mortality and morbidity worldwide....
by Michael Addelman, University of Manchester Credit: University of Manchester University of Manchester Researchers have developed a new biodegradable gel that can help to improve the delivery of cells directly into the living heart and could form a new generation of treatments to repair damage caused by a heart attack. The research is being presented...
by Technical University Munich Credit: Pixabay/CC0 Public Domain Following a heart attack, the human body is incapable of repairing lost tissue due to the heart’s inability to generate new muscle. However, treatment with heart progenitor cells could result in the formation of functional heart cells at injured sites. This new therapeutic approach is introduced by...
by Amanda Chase, Stanford University Graphical abstract. Credit: Circulation Research (2022). DOI: 10.1161/CIRCRESAHA.121.320090 Researchers at the Stanford Cardiovascular Institute have discovered how viruses like influenza and SARS-CoV-2 as well as their associated vaccines may increase the risk of heart attack, stroke, heart inflammation, and other cardiovascular complications. “Although flu has long been associated with heart attack and...
