CardioExchange, an NEJM practice community for medical professionals dedicated to improving cardiac patient care, was active from 2009 to 2015. CardioExchange fostered discussion between clinicians from across the globe.
Among patients with ST-segment elevation myocardial infarction and multivessel disease, physiology-guided angiography led to a lower risk of major cardiovascular events than conventional angiography-guided treatment.
In two placebo-controlled trials, oveporexton improved wakefulness, reduced daytime sleepiness, and lowered the cataplexy rate among patients with narcolepsy type 1. Increased urinary frequency and transient insomnia were common.
Among patients with syncope that remained unexplained after evaluation in the ED, immediate initiation of 14-day ECG monitoring did not result in significantly fewer patient-reported syncope episodes at 1 year than standard care.
Catheter-directed thrombolysis led to a lower risk of death, recurrent pulmonary embolism, or cardiorespiratory decompensation or collapse at 7 days than anticoagulation alone in intermediate-high–risk acute pulmonary embolism.
In patients with severe aortic stenosis and coronary artery disease, a strategy of transcatheter aortic-valve implantation before percutaneous coronary intervention was noninferior to PCI before TAVI for major clinical events at 1 year.
