Rapid pathway for diagnosing heart attacks does not improve emergency discharge rates

A rapid pathway for diagnosing heart attacks in the emergency department (ED) was as safe as a slower pathway but neither reduced the length of time patients spent in the ED nor increased direct discharge from the ED.

A common dietary nutrient feeds a gut pathway linked to atrial fibrillation

Researchers linked higher plasma TMAO to prevalent atrial fibrillation in 5,090 people and found that TMAO or choline supplementation accelerated AF onset, progression, atrial remodeling, and electrical dysfunction in mice. Inhibiting gut microbial TMA production lowered circulating TMAO and delayed AF in mice, identifying a potential therapeutic pathway that now requires human testing.

Novel gene therapy appears to be safe for Friedreich ataxia cardiomyopathy

A new gene therapy appears to be safe in patients diagnosed with Friedreich ataxia cardiomyopathy, a progressive and fatal inherited cardiac disease, according to a phase 1 clinical trial led by Weill Cornell Medicine researchers.

Running a marathon triggers measurable heart changes

Acute cardiac responses to marathon running include biomarker spikes and structural changes, though their long-term impact on heart health needs further study.

Review explores impact of extreme endurance running on heart health

Changes to the heart linked to marathon running vary by age, sex, and training level, finds a synthesis of the available data, published in the open access journal BMJ Open Sport & Exercise Medicine.

Losing weight improves heart muscle contraction in people with obesity and heart failure

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type of heart failure experience weakened heart muscles, and that losing weight may reverse some of these effects.

New guidelines and follow-up standards improve pulmonary embolism outcomes

Pulmonary embolism, or PE, is a serious and sometimes life-threatening condition that occurs when a blood clot travels to the lungs and blocks blood flow.

Can camel milk improve health? Review highlights benefits but warns against drinking it raw

A narrative review in Food Science & Nutrition examined studies published from 2000 to 2025 and found that camel milk contains bioactive compounds with potential glycemic, anti-inflammatory, gut, and other health benefits. It also stressed that raw, unpasteurized camel milk poses microbial and zoonotic risks, underscoring that safety remains a key part of the story.

AI-based ECG interpretation outperforms standard diagnosis of occlusive myocardial infarction

Artificial intelligence (AI)-based ECG interpretation outperformed standard pathways for the detection of occlusive myocardial infarction (MI), according to a study presented today at ESC Acute CardioVascular Care 2026,1 the annual congress of the Association for Acute CardioVascular Care (ACVC), a branch of the European Society of Cardiology (ESC).

New review calls for biologically grounded approach to psychiatric diagnosis

A comprehensive invited review published today in Brain Medicine confronts one of the most persistent paradoxes in modern medicine: psychiatry remains the only major clinical discipline that diagnoses complex illness primarily through conversation and symptom checklists, while fields such as oncology and cardiology long ago embraced laboratory markers, imaging, and molecular profiling.

Novel DAMP markers advance myocardial contusion detection

Researchers are exploring a new generation of biochemical markers that may help clinicians detect myocardial contusion. A frequently overlooked form of heart injury caused by blunt chest trauma, earlier and more accurately.

Influenza viruses can directly impair heart function

Mount Sinai researchers have identified a cellular mechanism linking infections from influenza A viruses (IAVs) to cardiovascular disease, providing critical insights on how influenza can damage the heart and increase the risk of a heart attack or other major cardiovascular event.

Why cardiologist evaluation matters after non-cardiac surgery

Interdisciplinary collaboration with cardiologists in non-cardiac surgery enhances patient outcomes, reducing cardiac event risks and improving survival rates.

Cardiology consults post-surgery may reduce heart risks and mortality rates

An estimated 4.2 million people die within 30 days of surgery worldwide each year. A new study, published in the European Heart Journal today (Thursday), suggests that deaths and serious heart disease might be prevented if some patients see a specialist heart doctor as part of their post-surgery care.

New blood biomarker tracks brain injury progression after ischemic stroke

A new blood marker reflects the extent of brain injury after an ischemic stroke and can predict patient outcomes months to years later.

ACE2 protein may play a protective role against high blood pressure and type 2 diabetes

A collaborative study from the MRC Laboratory of Medical Sciences (LMS) and Imperial College London has found that the protein ACE2 may play a protective role against two common conditions, high blood pressure and type-2 diabetes, which affect millions of people worldwide.

Circadian control of neutrophils limits heart damage after myocardial infarction

Neutrophils cause time-of-day–dependent collateral tissue damage after sterile injury through an intrinsic circadian program. Activating a CXCL12–CXCR4 checkpoint repositions neutrophils, limiting inflammatory injury without impairing antimicrobial defense.
