pyruvic acid has been researched along with Intermittent Claudication in 9 studies
Pyruvic Acid: An intermediate compound in the metabolism of carbohydrates, proteins, and fats. In thiamine deficiency, its oxidation is retarded and it accumulates in the tissues, especially in nervous structures. (From Stedman, 26th ed)
pyruvic acid : A 2-oxo monocarboxylic acid that is the 2-keto derivative of propionic acid. It is a metabolite obtained during glycolysis.
Intermittent Claudication: A symptom complex characterized by pain and weakness in SKELETAL MUSCLE group associated with exercise, such as leg pain and weakness brought on by walking. Such muscle limpness disappears after a brief rest and is often relates to arterial STENOSIS; muscle ISCHEMIA; and accumulation of LACTATE.

Evaluation of Cilostazol in Combination With L-Carnitine in Subjects With Intermittent Claudication[NCT00822172] | Phase 4 | 164 participants (Actual) | Interventional | 2008-09-30 | Completed | ||

Subjects were asked to complete a standardized exercise treadmill test using a modified Gardner protocol. Subjects walked on the treadmill until they were physically unable to walk further either as a result of their peripheral artery disease (PAD) symptoms or other non-PAD symptoms. The time during the conduct of the exercise treadmill test at which the subject first reported claudication symptoms is referred to as the claudication onset time (COT) and reported in minutes/seconds. The exercise treadmill test was conducted at Screening, Baseline, Day 90, and Day 180 visits. The log transformation is used to make highly skewed distributions less skewed. (NCT00822172)

Subjects were asked to complete a standardized exercise treadmill test using a modified Gardner protocol. Subjects walked on the treadmill until they were physically unable to walk further either as a result of their peripheral artery disease (PAD) symptoms or other non-PAD symptoms. This maximum time walked is referred to as the peak walking time (PWT) and reported in minutes/seconds. The exercise treadmill test was conducted at Screening, Baseline, Day 90, and Day 180 visits. The log transformation is used to make highly skewed distributions less skewed. (NCT00822172)

Subjects completed the Walking Impairment Questionnaire (WIQ) whereby they were asked about their maximal walking distance before having to rest as a result of claudication symptoms associated with their peripheral artery disease (PAD). The WIQ was administered at the Baseline, Day 90, and Day 180 visits. On the WIQ subjects were asked a series of questions related to their degree of physical difficulty that best described how hard it was for the subject to walk on level ground without stopping to rest. The questions began by asking the degree of difficulty walking around indoors, then 50 feet, 150 feet, 300 feet, 600 feet, 900 feet, and lastly 1500 feet. The responses range from None (best outcome) to Slight, then Some, then Much, then lastly Unable (worst outcome). The walking distance score was calculated from the 7 questions in the section by way of a weighted sum. A score of 100 indicated no walking impairment. A score of 0 corresponded to the highest degree of walking impairment (NCT00822172)
