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.

Email alerts boost valve replacement rates in older patients with aortic stenosis

New data finds older patients with severe aortic stenosis (AS) were more likely to receive aortic valve replacement (AVR) and survive when clinicians received automated email notifications with abnormal heart ultrasound results detecting AS.

Trends reveal growing burden of deaths from non-ischemic cardiogenic shock

New data from the CDC WONDER database finds deaths from heart attack-related cardiogenic shock (CS) decreased between 1999 and 2020, but deaths linked to heart failure (HF) and abnormal heart rhythms have risen sharply since 2010, particularly among men.

Novel algorithm improves detection of moderate-to-severe aortic stenosis

A novel detection algorithm spotted moderate-to-severe aortic stenosis (AS) with a sensitivity of 90.5% of all patients and 100% of African American patients.

Elevated Lp(a) levels associated with residual cardiovascular risk

New data analyzing more than 20,000 patients from three major NIH studies show that elevated Lipoprotein(a) [Lp(a)] is associated with residual cardiovascular risk and warrants aggressive risk reduction.

M-TEER procedure effectively treats mitral regurgitation in patients with calcification

Results from a new analysis show that patients with mitral annular calcification (MAC) who undergo minimally invasive mitral transcatheter edge-to-edge repair (M-TEER) experience similar reductions in mitral regurgitation (MR) and improvement in quality of life compared to those seen in patients without calcification.

COVID-19 patients with STEMI show higher one-year mortality rates

Findings from the North American COVID-19 Myocardial Infarction (NACMI) registry demonstrate significantly higher one-year mortality rates in patients with COVID-19 and ST-elevation myocardial infarction (STEMI) compared to patients with STEMI alone.

Real-world study examines cangrelor dosing for antiplatelet bridging after PCI

A multi-center retrospective cohort study examined how cangrelor has been used in real-world clinical practice around the time of surgery following percutaneous coronary intervention (PCI) and described differences in outcomes seen with different dosing approaches.

Blood return system dramatically reduces blood loss during pulmonary thrombectomy

The first comparative analysis from the ENGULF (A Safety and Feasibility Single-Arm Study of a Novel Catheter Thrombectomy Device For the Treatment of Pulmonary Embolism) trial shows that using blood return during continuous aspiration thrombectomy dramatically reduces blood loss by 97%, while maintaining hemodynamic efficacy and improving procedural efficiency.

Google search trends reflect a shift toward minimally invasive heart care

New research found that public interest in Transcatheter Aortic Valve Replacement (TAVR) increased substantially over the last decade, with Google search volume rising by 340% from 2015 to 2025, while searches for SAVR (Surgical Aortic Valve Replacement) declined by 42%.

Drug-coated balloons reduce the need for permanent heart stents

A new sub-study suggests that using a sirolimus-eluting balloon (SEB), a drug-coated balloon, can reduce the number of stents a patient may need, making it a safe and effective way to treat certain heart attacks or unstable chest pain.

Early heart pump use improves survival in patients experiencing cardiogenic shock

Findings from the Can Escalation Reduce Acute Myocardial Infarction Mortality in Cardiogenic Shock (CERAMICS) registry demonstrate that early use of a small heart pump improves outcomes in patients experiencing a severe form of heart failure called cardiogenic shock after suffering from a heart attack and undergoing a stenting procedure.

Treatment goals guide cardiogenic shock care more often in women

New findings from the Northwell-Shock Registry show that while women with acute myocardial infarction-related cardiogenic shock (AMI-CS) are less likely to receive invasive treatments, clinical decisions are driven by objective markers of illness severity rather than sex.

Tirzepatide significantly reduces cardiovascular risk in high-risk patients

Two new studies show that tirzepatide, a glucose-dependent insulinotropic polypeptide (GIP) receptor and glucagon-like peptide-1 (GLP-1) receptor agonist (RA), significantly reduces cardiovascular risk in high-risk patients, including those undergoing percutaneous coronary intervention (PCI) and those with obesity undergoing transcatheter aortic valve replacement (TAVR).

Minimally invasive PTAB shows promise for patients with complex peripheral arterial disease

New findings from a DETOUR2 substudy show that minimally invasive percutaneous transmural arterial bypass (PTAB) may offer a promising alternative to traditional leg bypass surgery for patients with complex peripheral arterial disease (PAD), even when distal vessel run off is severely limited.
