It was previously reported that inhibition of carnitine synthesis by 3-(2,2,2-trimethyl-hydrazinium) propionate (MET-88) restores left ventricular (LV) systolic and diastolic function in rats with myocardial infarction (MI). Preservation of the calcium uptake function of sarcoplasmic reticulum
To determine whether alterations in the mechanical properties and calcium transients of myocytes are important factors in the evolution of the postinfarcted heart, these physiological parameters were measured in the viable muscle cells of the left ventricle 6 h, 2-3 days, 1 wk, and 1 mo after
OBJECTIVE
In the present work, the effects of L-carnitine (LC) on postischemic cardiac hemodynamic functions and infarction size were studied in isolated rat heart.
METHODS
The hearts were subjected to 30 min regional ischemia followed by 120 min reperfusion. Then they were perfused by a drug-free

OBJECTIVE
Earlier studies have revealed sarcolemmal (SL) defects in congestive heart failure due to myocardial infarction; however, the mechanisms of SL changes in the failing heart are poorly understood. Since congestive heart failure is associated with various metabolic abnormalities including a
BACKGROUND
Administration of L-carnitine in patients with anterior acute myocardial infarction (AMI) prevents left ventricular remodeling. Current study was aimed to assess the effect of L-carnitine administration on mortality and heart failure in patients with anterior AMI.
METHODS
CEDIM 2 trial
A controlled study was carried out on 160 patients of both sexes (age between 39 and 86 years) discharged from the Cardiology Department of the Santa Chiara Hospital, Pisa, with a diagnosis of recent myocardial infarction. L-carnitine was randomly administered to 81 patients at an oral dose of g
The effect of L-acetyl carnitine (L-AC) on cerebral blood flow (CBF) was evaluated in 20 patients with chronic cerebrovascular disease, who suffered an ischaemic stroke at least 6 months before the study. All patients performed a CT scan and were investigated with xenon-133 by brain dedicated single
l-Carnitine is a cofactor in the energy metabolism pathways where it drives the uptake and oxidation of long chain fatty acids (LCFA) by mitochondria. LCFA lipotoxicity causes mitochondrial damage and results in an insufficient energy supply and a decrease in l-carnitine content limits LCFA flux and
Inhibition of carnitine palmitoyltransferase I with etomoxir increases sarcoplasmic reticulum Ca(2+)-transport and V(1) isomyosin expression. To test whether etomoxir attenuates contractile dysfunction after myocardial infarction, we compared the contractility of papillary muscles from etomoxir- and
A double blind randomized placebo controlled clinical trial was carried out to assess the efficacy and safety of L-carnitine in patients suffering from acute anterior wall myocardial infarction with respect to left ventricular function. Sixty patients (34 men, 26 women, mean age 56+11 yr.) with
Although the therapeutic strategies available for treating acute myocardial infarction (AMI) have evolved dramatically in recent decades, coronary artery disease remains the leading cause of death in our society, and the rates of recurrent myocardial infarction and mortality are still unacceptably
Limitation on infarct size, using propionyl-L-carnitine (Sigma-Tau) by itself and with the calcium entry blocker, tiapamil (Hoffmann-LaRoche), was evaluated in two groups of ten dogs each, during chronic (9 days) myocardial infarction. There were eight dogs that served as the control group. A
To elucidate 1-carnitine chloride effects ischemic myocardium for the possibility of a salvage of risk zone around necrosis in myocardial infarcts of dogs, a quantitative evaluation of the extent of myocardial infarcts was done by size detection with use of monastral blue and tissue dehydrogenase
The effect of administration of carnitine on the severity of myocardial infarction in rats induced by isoproterenol was studied by following histopathological and biochemical parameters. Carnitine afforded partial protection against myocardial infarction. Serum aspartate amino transferase (GOT) and
