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.

AI analysis of chest X-rays may reveal early signs of aging

Artificial intelligence may be able to reveal how fast your body is aging by analyzing a chest X-ray, according to a new study published in The Journals of Gerontology. Researchers found that a deep learning model was able to detect subtle, age-related changes in the heart, lungs, and overall health more effectively than leading DNA-based "epigenetic clocks."

Relationship quality impacts heart health, study shows

With heart disease as the leading cause of death worldwide, there is growing recognition that recovery is not only physical but also emotional and social. A new study shows that strong and supportive relationships can indeed improve heart health for individuals with cardiovascular disease.

First-of-its-kind mRNA system switches on therapeutic genes inside targeted cells

Researchers at the Icahn School of Medicine at Mount Sinai have developed a first-of-its-kind mRNA system that switches on therapeutic genes preferentially inside targeted cells-an advance demonstrated in studies in mice that could lay the groundwork for safer, more precise treatments for cancer and other diseases.

New data supports link between gum disease and heart disease

There is increasing evidence that gum disease is associated with increased risk of cardiovascular events, including heart attack, stroke, atrial fibrillation, heart failure and cardiometabolic health conditions. Effective prevention and treatment of gum disease, also called periodontal disease, could potentially decrease the burden of cardiovascular disease, according to a new scientific statement published today in the American Heart Association's flagship journal Circulation.

Mediterranean diet and healthy habits improve cancer survival rates

Being more physically active, following a balanced diet, not smoking, and keeping body weight and blood pressure under control: the same habits that protect the heart also prove decisive after a cancer diagnosis.

Single-pill combination medications may simplify treatment for adults with high blood pressure

Taking one pill that combines two or more blood pressure medications may help adults with high blood pressure (also known as hypertension) lower their blood pressure level faster and more effectively than taking multiple medications separately, and it may also reduce the risk of heart attack and stroke, according to a new scientific statement published today in the American Heart Association's journal Hypertension.

Mass General Brigham launches AI company to enhance clinical trial matching

Mass General Brigham is announcing the spinout of AIwithCare, a company founded by researchers from the health system who developed an artificial intelligence (AI) screening tool that significantly outperformed manual screening for determining a patient's eligibility and enrolling them in a clinical trial.

Increased epicardial fat volume linked to greater myocardial injury after infarction

Increased volume of epicardial adipose tissue, detected by cardiovascular imaging, was found to be associated with greater myocardial injury after a myocardial infarction.

Cuffless blood pressure devices show great promise as alternatives to traditional arm-cuff monitors

Cuffless devices to measure blood pressure, such as smartwatches, rings, patches and fingertip monitors, show great promise as alternatives to traditional arm-cuff monitors, however, they are not yet proven accurate enough to diagnose high blood pressure or guide treatment decisions, according to a new scientific statement published today in the American Heart Association's journal Hypertension.

Interventions to treat valvular heart disease in cancer patients significantly improve survival

Valvular heart disease, identified through cardiovascular imaging, is common in cancer patients. Interventions to treat valvular heart disease significantly improved survival.

Family history of cardiometabolic disease linked to early heart damage in adolescents

A new study among more than 1,500 British adolescents is the first in the world to assess the association between familial cardiometabolic diseases and the offspring's risk of premature heart damage by early adulthood.

Simple blood and urine tests could spare febrile infants from more invasive procedures

New evidence from a six-country study led by the Montreal Children's Hospital and Children's National Hospital shows simple blood and urine tests could spare many young infants with fevers from more invasive procedures.

Chronic kidney disease accelerates cognitive decline through heart-brain pathways

A new study published in the American Journal of Physiology - Heart and Circulatory Physiology reveals that chronic kidney disease (CKD) accelerates cognitive decline through interconnected damage to the heart and brain-and that these pathways differ markedly between men and women.
