In 466 patients with coronary artery disease having a catheter valve replacement, delaying stents reduced bleeding at every level of disease. But with complex disease, deferral was linked to more deaths, heart…
In California, opening a hospital able to unblock heart arteries with stents within 30 minutes of a community without one was linked to 20% lower 30-day mortality after a heart attack. In…
Pooling seven studies with 121,480 patients who had a coronary stent, a moderate-intensity statin plus ezetimibe was linked to a lower risk of new diabetes (RR 0.83) and similar heart events compared…
In 199 patients with a major heart attack from the ASSAIL-MI trial, lipoprotein(a) rose only slightly in the first days, from a median of 17 to 25 nmol/L, and few patients changed…
Pooling seven observational studies of 7887 people with type 2 diabetes after a heart attack or stent, high lipoprotein(a) was linked to about double the risk of another heart attack (hazard ratio…
A Cochrane review published Oct. 29, 2026, pooled 12 randomized trials with 1860 people and found no evidence that levodopa or dopamine agonists improve motor function after stroke. Serious side effects were…
In the LEAP-Block trial, published Oct. 28, 2026, in JAMA, people with heart block who got left bundle-branch area pacing had death, heart failure events or pacemaker upgrade in 2.4% of cases…

A meta-analysis of 20 randomized trials with 1009 adults found that diets rich in oleic acid did not change body weight, body fat, inflammation markers or blood pressure compared with low-oleic diets…
A review published Oct. 26, 2026, in Circulation argues that activin A, released by fat around the heart, drives stiffness and fibrosis in a form of heart failure with pulmonary hypertension, and…
A Korean study of 802 people with severe but symptom-free mitral valve leakage, published Oct. 1, 2026, in JAMA Network Open, linked surgery within 6 months of diagnosis to lower mortality than…
A study of Medicare data from 2007 to 2022, published Oct. 1, 2026, in JAMA Network Open, found that colder days were linked to more heart failure hospitalizations in adults 65 and…
