Among children treated for septic shock, no significant difference was seen in the incidence of death, new renal-replacement therapy, or persistent kidney dysfunction when fluid resuscitation was administered with balanced fluid as compared with 0.9% saline.

Among patients who received beta-blocker therapy beyond the first year after a myocardial infarction, discontinuation of beta-blocker therapy was noninferior to continuation with respect to a composite of death from any cause, recurrent myocardial infarction, or hospitalization for heart failure. (Funded by Patient-Centered Clinical Research Coordinating Center in the Ministry of Health and Welfa…

Among patients undergoing complex high-risk PCI, a strategy of routine IVUS-guided PCI performed with the use of prespecified stent-optimization criteria was not associated with a lower risk of target-vessel failure than angiography-guided PCI alone. (Funded by Boston Scientific; IVUS-CHIP ClinicalTrials.gov number, NCT04854070.).

Among patients with unprotected left main coronary artery disease, IVUS-guided PCI showed no additional benefit over angiography-guided PCI with respect to the incidence of stroke, myocardial infarction, any revascularization, or death from any cause at a median follow-up of 2.9 years. (Funded by Philips Image Guided Therapy Devices and Boston Scientific; OPTIMAL ClinicalTrials.gov number, NCT041…

Among patients with infrainguinal artery disease undergoing endovascular treatment, angioplasty with sirolimus-coated balloons led to a lower incidence of major adverse limb events at 1 year than angioplasty with uncoated balloons. (Funded by Concept Medical and others; SirPAD ClinicalTrials.gov number, NCT04238546.).

Among adolescent patients with obstructive hypertrophic cardiomyopathy, the reduction in left ventricular outflow tract obstruction was significantly greater with mavacamten than with placebo over a 28-week period. (Funded by Bristol Myers Squibb; SCOUT-HCM ClinicalTrials.gov number, NCT06253221.).

Among patients with severely impaired left ventricular function undergoing complex PCI, elective left ventricular unloading with a microaxial flow pump did not reduce the risk of major adverse clinical outcomes at a minimum of 12 months. (Funded by the U.K. National Institute for Health and Care Research; CHIP-BCIS3 ClinicalTrials.gov number, NCT05003817.).

Among patients with intermediate coronary lesions, vFFR-guided revascularization was noninferior to FFR-guided revascularization with respect to a composite of death, myocardial infarction, or revascularization at 1 year. (Funded by Pie Medical Imaging and Siemens Healthineers; FAST III ClinicalTrials.gov number, NCT04931771.).

Among patients with intermediate coronary-artery lesions undergoing physiological assessment in the cardiac catheterization laboratory, an angiography-guided strategy involving FFRangio was noninferior to a pressure-wire-guided strategy with respect to a composite end point of death, myocardial infarction, or unplanned clinically indicated coronary revascularization at 1 year. (Funded by CathWork…

Iptacopan therapy led to a significantly slower decline in kidney function than placebo. (Funded by Novartis; APPLAUSE-IgAN ClinicalTrials.gov number, NCT04578834.).

Among patients with atherosclerotic cardiovascular disease, targeting an LDL cholesterol level of less than 55 mg per deciliter resulted in a lower risk of cardiovascular events at 3 years than targeting a level of less than 70 mg per deciliter. (Funded by the Cardiovascular Research Center and Yuhan; Ez-PAVE ClinicalTrials.gov number, NCT04626973.).

In patients with acute, intermediate-risk pulmonary embolism, ultrasound-facilitated, catheter-directed fibrinolysis plus anticoagulation led to a lower risk of the composite of pulmonary embolism-related death, cardiopulmonary decompensation or collapse, or symptomatic recurrence of pulmonary embolism within 7 days than anticoagulation alone. (Funded by Boston Scientific; HI-PEITHO ClinicalTrial…

In adults with dermatomyositis that was resistant to previous therapy, the use of brepocitinib at a dose of 30 mg (but not at a dose of 15 mg) resulted in significant benefits with respect to a composite myositis index, skin disease severity, glucocorticoid tapering, and functional disability. (Funded by Priovant Therapeutics; ClinicalTrials.gov number, NCT05437263.).
