Recent developments of interest in cardiovascular medicine
Intensive blood pressure reduction may reduce the risk of hematoma expansion without improving outcomes in deep intracerebral hemorrhage, an exploratory trial analysis showed. (JAMA Neurology)
Low-dose aspirin for people without symptomatic cardiovascular disease was associated with more intracranial hemorrhage, and more intracerebral hemorrhage in Asian and low-BMI patients. (JAMA Neurology)
Google is getting into gene editing for heart disease with its Verve Therapeutics start-up helmed by heavy hitter Sekar Kathiresan, MD.
In news from the Heart Rhythm Society meeting in San Francisco:
- Rotor ablation flopped when added to conventional pulmonary vein isolation for atrial fibrillation in the REAFFIRM trial. (Mass Device)
- Novel pulsed field ablation technology isolated the pulmonary vein durably but "with a degree of tissue selectivity and a safety profile heretofore not described for cardiac ablation." (ACC.org)
- The Emblem subcutaneous ICD for primary prevention in low ejection fraction patients had a 95.8% rate of freedom from complications, a 99.6% rate of successful implantation at 30 days, and a 99.2% rate of successful defibrillator conversion. (Mass Device)
- Amid low rates of referral to electrophysiologists and low implantation ratesfor cardiac resynchronization therapy defibrillators (CRT-D) and ICDs in eligible patients, women and minorities got even fewer. (BioSpace)
