Shorten the blanking period after atrial fibrillation ablation, experts say

Research published in Heart Rhythm suggests that the three-month blanking period after atrial fibrillation (AF) ablation may not be necessary, as early AF recurrence is a predictor of late recurrence. The authors propose shortening the blanking period to one month, citing studies that show higher risks of long-term recurrence for patie...

Multidisciplinary research team creates computational models to predict heart valve leakage in children

A multidisciplinary team is developing computational models to predict heart valve leakage in children with specific birth defects. The models use 2D and 3D echocardiogram data to simulate the shape of valves and potential weak spots, enabling surgeons to plan surgeries more effectively.

Clinical trial finds nasal spray safely treats recurrent abnormal heart rhythms

A clinical trial found that a nasal spray called etripamil effectively and safely treated recurrent episodes of paroxysmal supraventricular tachycardia (PSVT) in patients. The study showed that two-thirds of participants experienced relief within an hour, with an average time needed for symptom relief being 17 minutes.

Unnecessary use of beta-blockers after a heart attack

A new study published in the New England Journal of Medicine found that half of patients discharged from hospital after a heart attack are treated with beta-blockers unnecessarily. The study shows that these patients have suffered a small heart attack and have retained heart function afterwards.

Stopping aspirin one month after coronary stenting procedures significantly reduces bleeding complications in heart attack patients

Researchers found that withdrawing aspirin one month after PCI significantly reduced major and minor bleeding incidents by 55% compared to dual antiplatelet therapy. The study, ULTIMATE-DAPT, showed no increase in adverse ischemic events, suggesting continuing aspirin may cause harm without benefit.

Want to cut US heart risks? Get more people into primary care, study suggests

A new study suggests that most essential care for cardiovascular health happens in general primary care clinics, but many at high risk don't receive it. The study found that large percentages of people with major cardiovascular risk factors didn't see a primary care provider or cardiologist in the past year.

Do’s and don'ts with direct oral anticoagulants

New research suggests that direct oral anticoagulants (DOACs) are less effective and safer in certain patient scenarios, such as those with mechanical heart valves or thrombotic antiphospholipid syndrome. DOACs should not be the standard treatment for all patients who need to treat or prevent blood clots.

Inaccurate pulse oximeter readings could limit transplants, heart pumps for Black patients with heart failure

Researchers found that pulse oximeters underestimate blood pumping and overestimate resistance, affecting treatment decisions. Direct blood oxygen measurement is crucial for accurate guidance, especially for Black patients already at higher risk.

Intravascular imaging significantly improves survival, safety, and outcomes in cardiovascular stenting procedures over conventional angiography

Using intravascular imaging to guide stent implantation significantly improves survival and reduces adverse cardiovascular events compared to angiography-guided PCI. The study found a 25% reduction in all-cause death, 45% reduction in cardiac death, and improved outcomes for patients with coronary artery disease.

Revolutionary genomic study sheds light on immune microenvironment in transplanted pediatric hearts

A team of researchers from Texas Heart Institute and Baylor College of Medicine have made a significant discovery about the underlying molecular cell states within transplanted pediatric hearts. They found that donor-derived tissue-resident macrophages are crucial for graft acceptance, but their loss leads to allograft failure.

Two-thirds of patients with low-risk pulmonary embolism are admitted to hospital unnecessarily

A study by researchers at Beth Israel Deaconess Medical Center found that despite guidelines supporting outpatient management, nearly two-thirds of low-risk PE patients remain hospitalized. The findings suggest that many patients with acute PE are being needlessly admitted to the hospital for inpatient management.
