Cardiology

Cardiology is the branch of internal medicine dealing with disorders of the heart and blood vessels. The field is commonly divided in the branches of congenital heart defects, coronary artery disease, heart failure, valvular heart disease and electrophysiology.

What is Cardiology?

The term cardiology is derived from the Greek words “cardia,” which refers to the heart and “logy” meaning “study of.” Cardiology is a branch of medicine that concerns diseases and disorders of the heart, which may range from congenital defects through to acquired heart diseases such as coronary artery disease and congestive heart failure.

Global collaboration can improve diagnosis and care for children with Kawasaki disease

International collaboration in research, diagnosis and care is critical to reducing the risk of serious heart conditions for children with Kawasaki disease worldwide, according to a new science advisory published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association.

Stent-assisted coiling and flow diverters effectively treat rare basilar artery cases

Basilar trunk artery aneurysms (BTAs) are among the rarest and most complex types of brain aneurysms, occurring in a critical vessel that supplies blood to the brainstem. Because of their location and low incidence, there has been limited research guiding how best to treat them, leaving neurosurgeons with few large datasets to inform clinical decisions.

Study traces adult heart disease risk back to the womb

A child's future heart health may be partially shaped before they are born, reports a new Northwestern Medicine study that found pregnancy complications are linked to poorer cardiovascular health in offspring more than 20 years later.

AI models predict sudden cardiac arrest risk using health records

Researchers have developed artificial intelligence (AI) models that can scrutinize electronic health records (EHR) and electrocardiograms to identify individuals in the general population at elevated risk for sudden cardiac arrest - a condition that causes more than 400,000 U.S. deaths annually and has a survival rate of only 10%.

Combined workouts and HIIT significantly lower daily blood pressure

Aerobic and resistance training combined, and high intensity interval training (HIIT), are associated with significant reductions in blood pressure over 24 hours, finds a pooled data analysis of the available evidence for several different types of structured exercise, and published online in the British Journal of Sports Medicine.

New genetic link found for sudden cardiac death in young people

Short QT syndrome is a genetic disease that leads to sudden cardiac death at a young age. Mutations in the SLC4A3 gene, which regulates bicarbonate-chloride exchange, were recently described as a potential cause. An international research team, including a group from Ruhr University Bochum, Germany, investigated this possibility.

New research identifies stress response as trigger for heart inflammation

After a heart attack, the body rapidly floods the injured heart with neutrophils - white blood cells that help repair damage but can also make it worse when too many arrive too quickly.

New genetic risk report reveals hidden heart disease risk before symptoms appear

Researchers developed and externally validated integrated polygenic risk scores for eight cardiovascular conditions using large U.S.-based biobank data. The clinically orderable report may help identify inherited cardiovascular risk that traditional clinical markers can miss, although broader prospective validation is still needed.
