clonidine and Precordial Catch

clonidine has been researched along with Precordial Catch in 2 studies

Clonidine: An imidazoline sympatholytic agent that stimulates ALPHA-2 ADRENERGIC RECEPTORS and central IMIDAZOLINE RECEPTORS. It is commonly used in the management of HYPERTENSION.
clonidine (amino form) : A clonidine that is 4,5-dihydro-1H-imidazol-2-amine in which one of the amino hydrogens is replaced by a 2,6-dichlorophenyl group.

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 (Metabolism Equivalents)

Physical functional disability measured by exercise stress testing. Functional capacity was measured as metabolism equivalents (METs), exercise duration, and exercise-induced chest pain. (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)

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."
