Optimal Blood Pressure for the prevenTIon of Major vAscuLar Events in Stroke Patients

Not Applicable

Active, not recruiting

• Conditions: Ischemic Stroke; Blood Pressure; Cognitive Impairment; Vascular Diseases
• Interventions: Drug: Intensive Control of Systolic Blood Pressure (SBP); Drug: Standard control of Systolic Blood Pressure (SBP)

• Registration Number: NCT04036409
• Lead Sponsor: Hospital Israelita Albert Einstein

Brief Summary

Elevated blood pressure (BP) consists of a major public health concern especially in low and middle income countries. Besides being a highly prevalent condition, it is also a risk factor for several major cardiovascular events including stroke (which consists of the second leading cause of death in developing countries) and coronary artery disease, and is also related to cognitive decline. The OPTIMAL Stroke trial consists of a two-arm, multicenter, randomized clinical trial designed to test whether a lower target systolic blood pressure (SBP) as compared to the currently recommended target for stroke patients will reduce the occurrence of major cardiovascular events.

Time to total death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina or hospitalization for heart failure [ Time Frame: From randomization; for approximately a median of 3.5 years ]	From randomization; for approximately a median of 3.5 years	Time to first event of total death, non-fatal myocardial infarction (MI), non-fatal stroke, hospitalization for unstable angina or hospitalization for heart failure
Time to non-fatal MI, non-fatal stroke, or total death	From randomization; for approximately a median of 3.5 years	Time to non-fatal MI, non-fatal stroke or total death.
Time to Death	From randomization; for approximately a median of 3.5 years	Time to all cause death
Time to Renal Death	From randomization; for approximately a median of 3.5 years	Time to death from renal causes
Time to Renal Outcome	From randomization; for approximately a median of 3.5 years	Time to Renal Outcome, defined as a 50% reduction in the glomerular filtration rate (GRF) associated with a final GFR of \< 60 mL/min/1.73m2 in patients without chronic kidney disease (GFR 60-90 mL/min/1.73m2) at baseline.
