Interim analysis of ambulance logistics and timings in patients recruited into the Rapid intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2) (2018)
Conference Proceeding
Dixon, M., Scutt, P., Appleton, J. P., Spaight, R., Johnson, R., Siriwardena, A. N., & Bath, P. M. (2018). Interim analysis of ambulance logistics and timings in patients recruited into the Rapid intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2).

Introduction: Stroke is a severe condition with high morbidity and mortality. Despite treatment effects in acute stroke being predominantly time dependent (e.g. thrombolysis and thrombectomy), proven treatments are hospital based and require prior br...

International Journal of Stroke, 14(3), 298-305. https://doi.org/10.1177/1747493018816451

Background: High blood pressure (BP) is common in acute stroke and associated with a worse functional outcome. Glyceryl trinitrate (GTN), a nitric oxide donor, lowers BP in acute stroke and may improve outcome. Aims: RIGHT-2 tested the feasibility o...

Rationale: Glyceryl trinitrate, a nitric oxide donor, is a candidate treatment for acute stroke; it lowers blood pressure, does not alter cerebral blood flow or platelet function and is neuroprotective in experimental stroke. The ongoing rapid interv... Read More about Statistical analysis plan for the ‘Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2)’.

Ambulance-delivered transdermal glyceryl trinitrate versus sham for ultra-acute stroke: rationale, design and protocol for the Rapid Intervention with Glyceryl trinitrate in Hypertensive stroke Trial-2 (RIGHT-2) trial (ISRCTN26986053). International Journal of Stroke, https://doi.org/10.1177/1747493017724627

Rationale: Vascular nitric oxide levels are low in acute stroke and donors such as glyceryl trinitrate have shown promise when administered very early after stroke. Potential mechanisms of action include augmentation of cerebral reperfusion, thrombol...
