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.

Sirolimus-eluting balloon emerges as a safe and effective option for coronary in-stent restenosis

A new drug-eluting balloon can perform just as well as the standard treatment for patients with coronary in-stent restenosis (ISR) undergoing repeated percutaneous coronary intervention (PCI).

Study provides first worldwide validation of new GLIS model in older patients with heart failure

With populations aging rapidly worldwide, heart failure has become one of the most pressing medical and social challenges.

AI-driven ECG improves detection of severe heart attacks

Using artificial intelligence (AI) to analyze electrocardiograms (ECG) improved detection of severe heart attacks, including those that presented with unconventional symptoms, or atypical ECG patterns, and reduced false positives, according to a study published in JACC: Cardiovascular Interventions and simultaneously presented at TCT 2025 in San Francisco.

Women gain stronger heart protection from exercise than men, study reveals

Researchers analyzing over 85,000 UK Biobank participants found that women gain greater cardiovascular benefits from physical activity than men, needing only half the exercise to achieve similar reductions in coronary heart disease and mortality risk. The study underscores the importance of sex-specific guidelines for CHD prevention.

Clinical Frailty Scale can quickly predict mortality in patients with heart failure

Frailty is closely linked to adverse outcomes in older adults, particularly those with heart failure. Numerous epidemiologic studies show that frailty has important prognostic value in this population, underscoring the need for routine assessment.

Cutting balloon angioplasty proves noninferior to intravascular lithotripsy in treating calcified coronary lesions

Results from the first randomized controlled trial to directly compare the safety and efficacy of cutting balloon (CB) angioplasty to intravascular lithotripsy (IVL) prior to drug-eluting stent (DES) implantation for the treatment of calcified coronary artery disease found CB to be noninferior to IVL.

Circadian rhythm disruptions may increase the risk of cardiovascular disease

As modern lifestyles increasingly challenge the body's natural circadian rhythm, the American Heart Association is spotlighting the potential health consequences of regular disruptions to our body's internal clock with a new scientific statement published today in its flagship journal Circulation.

Updated guidelines published for pediatric CPR and emergency cardiovascular care

The American Academy of Pediatrics and the American Heart Association (the Association), a relentless force changing the future of health for everyone everywhere, have published updated guidelines for cardiopulmonary resuscitation and emergency cardiovascular care for newborn and pediatric populations.

A little walking goes a long way: 4,000 steps linked to lower mortality in older women

Older women who achieved at least 4,000 steps per day for just one or two days each week showed significantly lower risks of death and cardiovascular disease. The study suggests that total step volume, not frequency, drives these benefits, redefining what “enough movement” means for health.

Semaglutide can offer important heart benefits that go beyond weight loss

A new analysis of the SELECT trial – the largest and longest clinical trial to date examining the cardiovascular benefits of semaglutide (a medication used to support weight loss and diabetes management) – confirms it also lowers the risk of major heart problems in people who are overweight or obese and already have heart disease, even if they don't have diabetes.

Novel PET scan quickly predicts functional recovery after heart attack

A new approach to PET imaging offers a promising way for physicians to promptly identify patients who are at risk for poor functional recovery after a heart attack, according to new research published in The Journal of Nuclear Medicine.

Updated CPR guidelines provide expanded recommendations for managing choking and opioid overdose

The "2025 American Heart Association Guidelines for Cardiopulmonary Resuscitation (CPR) and Emergency Cardiovascular Care (ECC)," published today in the Association's flagship journal, Circulation, marks the first full revision of lifesaving resuscitation guidance since 2020.

Abstinence or limiting alcohol intake may lead to clinically meaningful blood pressure reductions

Light-to-moderate alcohol consumption is associated with increases in blood pressure (BP) and stopping drinking – even drinking less – may lead to clinically meaningful BP reductions, according to a study published today in JACC, the flagship journal of the American College of Cardiology.

Neighborhood environments can influence a child's risk of developing type 2 diabetes

Type 2 diabetes (T2D), once considered an adult-onset disease, is increasing at alarming rates in children and adolescents. Before the mid-1990s, just 1% to 2% of youth with diabetes had T2D.

Study reveals high sudden cardiac death rates in female bodybuilders

Sudden cardiac death is responsible for an unusually high proportion of deaths in female bodybuilders worldwide, according to research published in the European Heart Journal today (Tuesday).

Preexisting hyperlipidemia in pregnancy linked to obstetric and early heart risks

Preexisting hyperlipidemia in pregnancy is associated with heightened risks of obstetric complications and early cardiovascular events in the first five-years postpartum, according to a new study being presented at ACC's Cardio-Obstetrics Essentials: Team-Based Management of Cardiovascular Disease and Pregnancy conference.

Artificial intelligence guides personalized treatment for heart patients

A landmark international study led by the University of Zurich has shown that artificial intelligence can assess patient risk for the most common type of heart attack more accurately than existing methods.

Air pollution plays a significant role in the development of metabolic disorders

Long-term exposure to fine air pollution can impair metabolic health by disrupting the normal function of brown fat in mice. A study co-led by the University of Zurich shows that this occurs through complex changes in gene regulation driven by epigenetic mechanisms.

New program aims to educate clinicians on the latest advances in heart failure treatment

The American College of Cardiology is launching a new program to educate clinicians on the latest advances, medications and interventions emerging in heart failure (HF) management and treatment. Transformation of HF Care: New Horizons in Treatment aims to ensure the prompt and evidence-based use of the latest HF therapies to improve outcomes among individuals with HF.
