Brief summary

Patients on chronic hemodialysis without obstructive coronary artery disease identified by coronary angiography were randomly divided into the two groups: carnitine group and control group. SPECT using FFA analogue, BMIPP, was performed before and one year after intravenous administration of L-carnitine (1000 mg on every dialysis session). Control group received the examination of BMIPP SPECT at the same time of the carnitine group. The effects of chronic intravenous administration of L-carnitine on myocardial fatty acid metabolism were investigated among this population.

Detailed description

Patients on chronic hemodialysis in Toujinkai hospital who had no obstructive coronary artery disease identified by coronary angiography and left ventricular dysfunction were randomly divided into the two groups: carnitine group and control group. To evaluate the possible effect of carnitine administration on myocardial fatty acid metabolism, SPECT using FFA analogue, BMIPP, was performed before and one year after intravenous administration of L-carnitine (1000 mg on every dialysis session). Control group received the examination of BMIPP SPECT at the same time of the carnitine group. Circulating concentrations of total, free, and acyl L-carnitine were measured every three months in the carnitine group. Clinical data including blood chemistry, blood pressure, or cardiac functions by echocardiography were obtained every 6 months in both groups. The effects of chronic intravenous administration of L-carnitine on myocardial fatty acid metabolism and cardiac functions were investigated among this population.
