 What pregnancy reveals about a woman’s future heart healthWhat pregnancy reveals about a woman’s future heart health
 
Pregnancy acts as a natural cardiovascular stress test, revealing hidden heart disease and identifying women at higher long-term risk after complications such as preeclampsia, gestational diabetes, and preterm birth. The review highlights major evidence gaps in cardio-obstetric care and calls for stronger postpartum screening, dedicated women’s health clinics, and better inclusion of reproductive-age women in research.

Researchers developed Passive Heart-Rate Monitoring, a deep-learning smartphone system that estimates heart rate and daily resting heart rate from eight-second facial videos captured during normal phone use. Validated on more than 160,000 videos, the system met accuracy targets across skin-tone groups, although usable measurement rates were lower in the darkest skin-tone group and clinical use still requires further testing.
 
   Frailty flags poorer blood pressure control in older womenFrailty flags poorer blood pressure control in older women
 
In 1,038 older adults with hypertension attending outpatient clinics in Vietnam, frailty was more common in women than men, while overall rates of suboptimal blood pressure were similar by sex. Frailty was associated with about twice the odds of suboptimal blood pressure in women, but not in men, highlighting the need to study sex-specific and frailty-informed hypertension care.
 
   Protein repair defects linked to hidden heart failureProtein repair defects linked to hidden heart failure
 
Researchers in the del Monte Lab at the Medical University of South Carolina (MUSC) are the first to observe defects in the protein repair system associated with the peculiar, misfolded protein plaques previously observed in patients with idiopathic dilated cardiomyopathy (IDCM ).
 
   Pulse-wave tracking at home catches spontaneous normal heart rhythms earlyPulse-wave tracking at home catches spontaneous normal heart rhythms early
 
Smartphone-based heart rhythm monitoring from home can reduce same-day cancellations and help save significant healthcare resources ahead of planned electrical cardioversion in patients with atrial fibrillation. This is shown in a new study published in JAMA Cardiology by researchers at Karolinska Institutet and Danderyd Hospital.
 
 American Heart Association launches national heart transplant research network
 
American Heart Association launches national heart transplant research networkNearly 60 years after the first successful heart transplant, the American Heart Association, a relentless force changing the future of health for everyone everywhere, is launching a bold new initiative to fundamentally transform how heart transplant care is delivered across the United States - addressing long-standing gaps in innovation, equity and patient outcomes.
 
 
 Seven-second X-ray scan detects severe pulmonary valve regurgitation with high accuracy
 
Researchers at Kyushu University have developed a simple, rapid, and low-radiation X-ray technique that can evaluate the severity of a heart condition known as pulmonary valve regurgitation-a common and clinically significant complication after surgical repair of a congenital heart defect known as Tetralogy of Fallot.
 
 
 Diabetes drug dramatically lowers heart failure risk in genetic carriers
 
Diabetes drug dramatically lowers heart failure risk in genetic carriersRare genetic variants known to cause cardiomyopathy, an inherited cause of a weak heart, can increase the risk of patients developing heart failure.
