Abstract:
The object of this study was to assess the cardiovascular tolerance and efficacy of early nicotine substitution therapy in 100 patients admitted to the Coronary Care Unit for acute coronary syndromes (ACS). The files of the first 100 consecutive patients having received nicotine substitution therapy immediately after an ACS were consulted retrospectively and a questionnaire was sent to all patients. A reply was obtained in 90% of cases. In this series, there was a 7% rate of cardiovascular events in the days following hospital discharge, comparable to previously reported results. The smoking relapse rate at six months after the ACS was 38.9%, a percentage which was less than in previously reported series. Although consultations to help stop smoking and nicotine substitution did not seem to have significant benefits in this study, the authors recommend continuing and improving the management of coronary patients who smoke.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
