This paper describes a GC-MS method for the analysis of the carboxylic acid metabolite (SR26334, II) of methyl (+)-(S)-alpha-(o-chlorophenyl)-6,7-dihydrothieno[3,2-c]pyridine-5( 4H)-acetate hydrogensulfate (clopidogrel, SR 25990, I) in plasma and serum. The analytical procedure involves a robotic liquid-liquid extraction with diethyl ether followed by a solid-liquid extraction on C18 cartridges. The derivatization process was performed using n-ethyl diisopropylethylamine and alpha-bromo-2,3,4,5,6-pentafluoro toluene.

Based on a retrospective study, we report the clinical and electrophysiological characteristics of 62 cases of effort-induced atrio-ventricular block (AVB). The diagnosis of effort-induced AVB was established by stress test and/or Holter ECG. This series consisted of 18 women and 44 men with a mean age of 64 +/- 13 years.

In order to determine the role of tilt testing in the aetiological diagnosis of syncope unexplained by electrophysiological investigation, the authors retrospectively studied the results of this test in 275 patients with a mean age of 64 +/- 16 years. These 275 patients were divided into two groups: group I: 43 patients with a mean age of 50 +/- 19 years presenting with vagal syncopes, group II: 232 patients with unexplained syncope, probably vagal: group IIa (120 patients, mean age: 67 +/- 15 years), sudden syncope: group IIb (112 patients, mean age: 67 +/- 13 years). The electrophysiological investigation was inconclusive in every case.

The authors report a case of a cerebral embolism, with a rapidly resolving course, during late fibrinolysis using tissue plasminogen activator in a patient with a posterolateral myocardial infarction. A review of the literature is used as basis for considering the effects of fibrinolytic treatment on left intraventricular thrombi during the acute phase of myocardial infarction. The risk of systemic embolism during such treatment is stressed.
