Immune signaling pathway protects newborn heart cells from injury

Researchers at the University Hospital of Bonn (UKB) and the University of Bonn have identified a previously unknown signaling pathway in the immune system that helps newborn heart cells survive and regenerate after injury.

A 30-year study found a surprising link between alcohol, survival and heart attack risk

In a 30-year study of 973 middle-aged Swedish male automotive workers, alcohol consumption was associated with lower all-cause mortality and longer estimated time to death, while beer consumption was linked to a higher likelihood of myocardial infarction. No significant association was found between alcohol consumption and stroke, and the authors cautioned that socioeconomic differences, self-reported intake, and other unmeasured factors may have influenced the findings.

Huge philanthropic grant funds pioneering stem cell-based heart attack therapy

In a landmark moment for both the treatment of heart disease and philanthropic support, The Marcus Foundation has awarded the head of USC Stem Cell Center, Chuck Murry, MD, PhD, $28.7 million to advance a clinical trial testing a stem cell-based therapy designed to regenerate damaged tissue after a heart attack.

Waist size predicts heart disease risk better than body mass index

The size of a person's midsection is a better indicator of cardiovascular disease risk when compared to their body mass index (BMI) alone, according to a study published in JACC, the flagship journal of the American College of Cardiology.

Tirzepatide lowers heart attack and cardiovascular event risk in adults with type 2 diabetes

In a US cohort of 52,971 adults with type 2 diabetes and established atherosclerotic cardiovascular disease, tirzepatide initiation was associated with a lower one-year risk of major adverse cardiovascular events than sitagliptin. The benefit was driven mainly by lower myocardial infarction and all-cause mortality hazards, although the authors cautioned that mortality findings may be influenced by residual confounding.

Explainable AI helps predict dangerous bleeding after severe heart attacks

Researchers at Indiana University School of Medicine have developed and tested a six-point scoring system that can help identify patients at high risk of internal bleeding in damaged heart muscle after a severe heart attack using explainable artificial intelligence (XAI).

Genetic analysis of 1 million people points to FNIP1 as a promising metabolic target

Mega-scale exome sequencing of 1,032,116 people identified 59 independent genes linked to the TG:HDL ratio, including 44 rare-coding associations not detected in the previous largest analysis. Ultra-rare FNIP1 loss-of-function variants were associated with favorable fat distribution, lower liver fat and glycemia, and around 60% lower odds of a composite cardiometabolic disease outcome.

Severe COVID-19 reactivates dormant viruses and may leave a lasting viral signature

A longitudinal study of 1,154 hospitalized COVID-19 patients found widespread reactivation of chronic Herpesviridae and Anelloviridae, with distinct viral patterns linked to disease severity, inflammation, and clinical outcomes. Anelloviridae also persisted during convalescence and were associated with physical deficits in long COVID, although the study did not establish causation.

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.

ACC introduces cardiogenic shock designation to improve heart attack care

The American College of Cardiology (ACC) is introducing a new cardiogenic shock designation to improve outcomes for one of the most life-threatening complications of a heart attack.

Semaglutide vs. liraglutide: Head-to-head study reveals a diabetes risk difference

Researchers compared semaglutide with liraglutide in 57,456 insured adults without recorded diabetes or cardiovascular disease who initiated formulations indicated for chronic weight management. Semaglutide users had a lower risk of incident diabetes, particularly beyond six months of follow-up, but limited cardiovascular events prevented a precise comparison of cardiovascular risk.

G&H highlights end-to-end diagnostic device development at ADLM 2026

At the ADLM Clinical Lab Expo 2026, G&H will showcase how diagnostic and medical device companies can accelerate the development and commercialization of innovative healthcare technologies through a single partner offering multidisciplinary engineering, precision optics, photonics and ISO 13485-certified manufacturing.

New model improves short- and long-term disease risk prediction

Researchers developed ALADYNOULLI, a Bayesian generative model that combines longitudinal health records, age, and polygenic risk to identify reproducible disease signatures across more than 683,000 participants. In UK Biobank testing, the framework achieved stronger short- and long-term risk discrimination than established clinical scores while revealing disease subgroups and genetic associations.

Irritable patients changed physicians’ emotions but not decisions

Irritable patient behavior influences physician emotions but does not alter clinical assessments, emphasizing the need for emotional resilience training.

Micro and nanoplastics in the blood linked to increased heart attack risk factors

People who have suffered a serious heart attack had higher levels of micro and nanoplastics in their blood, compared to patients diagnosed with chronic ischemic heart disease and those who have normal blood vessels supplying the heart, according to a study published in the European Heart Journal today (Wednesday).

GLP-1RAs linked to lower risk of amputation in diabetes with PAD

Research indicates GLP-1RAs may decrease limb complications in type 2 diabetes with PAD, though more randomized studies are required to confirm efficacy.

Targeting specific immune pathways could prevent severe reperfusion injury

IRI is a shared pathological process in myocardial infarction, ischaemic stroke, acute kidney injury, lung injury, and graft dysfunction after transplantation.

Study links COVID-19 to higher sleep apnea risk years after infection

Researchers analyzed more than 910,000 adults and found that SARS-CoV-2 infection was associated with a higher adjusted risk of new-onset obstructive sleep apnea up to 4.5 years later. The association appeared in both hospitalized and non-hospitalized COVID-19 patients, supporting targeted screening in higher-risk post-COVID groups while highlighting the need for objective sleep testing.

Pioneering technique maps the proteome of individual cardiomyocytes

Two research teams at the Centro Nacional de Investigaciones Cardiovasculares Carlos III (CNIC) have developed a pioneering technique in Spain to characterize the proteome of individual cardiomyocytes-the cells responsible for heart contraction.

Early diabetes drug treatment links to better survival after diagnosis thresholds

A Korean target trial emulation found that starting antidiabetic medication within 12 months of newly crossing type 2 diabetes diagnostic thresholds was associated with lower five-year all-cause mortality. MACE risk was numerically lower with earlier treatment, but the reductions in cardiovascular events were not statistically significant, underscoring the need for larger studies.
