dipyridamole and Active Hyperemia

dipyridamole has been researched along with Active Hyperemia in 74 studies

Dipyridamole: A phosphodiesterase inhibitor that blocks uptake and metabolism of adenosine by erythrocytes and vascular endothelial cells. Dipyridamole also potentiates the antiaggregating action of prostacyclin. (From AMA Drug Evaluations Annual, 1994, p752)
dipyridamole : A pyrimidopyrimidine that is 2,2',2'',2'''-(pyrimido[5,4-d]pyrimidine-2,6-diyldinitrilo)tetraethanol substituted by piperidin-1-yl groups at positions 4 and 8 respectively. A vasodilator agent, it inhibits the formation of blood clots.

Trial Outcomes

Endothelial Dysfunction (FMD)

"Endothelial dysfunction refers to altered vasoactive, anticoagulant, and anti-inflammatory properties of endothelium, and dysregulated vascular growth remodeling that results from a loss of nitric oxide (NO) bioactivity in the endothelium. Brachial Artery Reactivity Testing (BART), high-frequency ultrasonographic imaging of the brachial artery, evaluates flow-mediated vasodilation (FMD), an endothelium-dependent function. The technique provokes the release of nitric oxide, resulting in vasodilation that can be quantitated as an index of endothelial dysfunction.~Flow-mediated vasodilation is typically expressed as the change in post-stimulus diameter as a percentage of the baseline diameter [diameter after cuff deflation - baseline diameter / baseline diameter) x 100]."

Inducible Myocardial Ischemia

Inducible myocardial ischemia measured by P-31 gated magnetic resonance cardiac spectroscopy (MRS) is reported as change (∆) in PCr/ATP ratio, with isometric submaximal handgrip stress. PCr/ATP ratio defined as (stress-[average of rest and recovery periods]) / average of rest and recover periods X 100, and expressed as % mean ± SD. For this trial, myocardial ischemia was pre-specified as a fall in quantitative PCR/ATP ratio >20% from rest, and a lower value is considered indicative of greater ischemia. (NCT00600106)

Physical Functional Disability - Functional Capacity (Exercise Induced ST Segment Depression)

"Physical functional disability measured by exercise stress testing. Functional capacity was measured as metabolism equivalents (METs), exercise duration, and exercise-induced chest pain.~In electrocardiography, the ST segment connects the QRS complex and the T wave and has duration of 80 to 120 ms. It should be essentially level with the PR and TP segment. The normal ST segment has a slight upward concavity. Flat, downsloping, or depressed ST segment may indicate coronary ishcemia. Positive treadmill exercise stress test (>1.0 mm horizontal / downsloping or >1.5 upsloping ST segment depression measured 0.08 msec after the J point)." (NCT00600106)

Physical Functional Disability - Functional Capacity (METs)

Physical functional disability measured by exercise stress testing. Functional capacity was measured as metabolism equivalents (METs), exercise duration, and exercise-induced chest pain. A MET is defined as the resting metabolic rate, that is, the amount or oxygen consumet at rest, sitting quietly in a chair, approximately 3.5 ml O2 / kg / min (1.2 kcallmin for a 70-kg person). As such, work at METs requires twice the resting metabolism or 7.0 ml O2/kg/min, and so on. (NCT00600106)

Physical Functional Disability - Functional Capacity (Stress Induced ST Segment Depression)

"Physical functional disability measured by exercise stress testing. Functional capacity was measured as metabolism equivalents (METs), exercise duration, and exercise-induced chest pain.~In electrocardiography, the ST segment connects the QRS complex and the T wave and has duration of 80 to 120 ms. It should be essentially level with the PR and TP segment. The normal ST segment has a slight upward concavity. Flat, downsloping, or depressed ST segment may indicate coronary ishcemia. Positive treadmill exercise stress test (>1.0 mm horizontal / downsloping or >1.5 upsloping ST segment depression measured 0.08 msec after the J point)." (NCT00600106)

Quality of Life - Health Survey

"Quality of life assessed by cardiac symptoms and psychological questionnaires (SF 36 scale - Short Form Health Survey) The SF-36 includes one multi-item scale that assesses eight health concepts: 1) limitations in physical activities because of health problems; 2) limitations in social activities because of physical or emotional problems; 3) limitations in usual role activities because of physical health problems; 4) bodily pain; 5) general mental health (psychological distress and well-being); 6) limitations in usual role activities because of emotional problems; 7) vitality (energy and fatigue); and 8) general health perceptions.~Each scale is directly transformed into a 0-100 scale on the assumption that each question carries equal weight. The lower the score the more disability. The higher the score the less disability i.e., a score of zero is equivalent to maximum disability and a score of 100 is equivalent to no disability."
