Trial Outcomes & Findings for The Antihypertensives and Vascular, Endothelial and Cognitive Function Trial (NCT NCT00605072)

NCT ID: NCT00605072

Last Updated: 2013-02-15

Results Overview

This test requires the connection of sequentially numbered circles (A), and the connection of circles marked by numbers and letters in alternating sequence (B). This test is considered a benchmark of executive function. The test score is the time required to complete the task in seconds.

PRIMARY outcome

Timeframe: Baseline-12 months

This is a 12-item list learning test in which individuals are presented three learning and recall trials followed by a delayed recall and 24 item recognition test. The HVLT-R has been identified as an ideal memory measure for elderly patients, and appropriate reliability and validity have been shown in older individuals. The test score is the number of correct answers in the delayed recall ( score range 0-12)

PRIMARY outcome

Timeframe: Baseline-12 months

This test consists of series of digits of increasing length, some of which are recited as presented, and some of which are to be recited in reversed order. The forward digit span score ranges from 0 (ie cannot repeat two digits) to 8 ( participant can repeat up to 8 digits)

SECONDARY outcome

Timeframe: Baseline-12 months

Blood pressure was measured as follows: the participant was in the sitting position, rested for 5 minutes, no caffeine or smoking 2 hours prior to measurement, using appropriate cuff size (covering 60% of upper arm length and 80% of arm circumference), correct cuff placement (1-2 inches above brachial pulse on bare arm), and the bell of the stethoscope. The systolic blood pressure was defined as the pressure corresponding to the first korotkoff sounds (K1) and the diastolic as the pressure corresponding to the last korotkoff sound (K5). Blood pressure was measured in both arms and recorded
