[Do arrhythmias after infarction deter patients from smoking?].
Although the short-term outcome of patients treated by thrombolysis during the acute phase of myocardial infarction is now well known, data concerning the repercussions of the coronary accident on smoking are less clearly established. This aspect is particularly important, as cessation of smoking is one of the most effective measures in the context of secondary prevention, with an excellent cost-benefit ratio. Between 1985 and 1991, 218 consecutive patients underwent thrombolysis for myocardial infarction. With a follow-up of 35 +/- 20 months, 11.5% of patients have died, including 6% while in hospital. A questionnaire was sent to 193 surviving patients with a response rate of 97.4%, 27.3% of patients continued to smoke after the myocardial infarction. Smoking patients were younger (p = 0.001) and had generally returned to work (p = 0.05). Continuation of smoking was not influenced by either the patency of the artery or the type of revascularization, and was not correlated with residual symptoms. The frequency of arrhythmias during the acute phase was not related to previous smoking. On the other hand, smoking patients who survived after an infarction appear to quit smoking twice as frequently when they had experienced a cardiac arrhythmia during the acute phase of the infarction (p = 0.005), as confirmed by multivariate analysis. Can the "stress" induced by the arrhythmia, possibly combined with the doctor's reactive anxiety explain cessation of smoking in these patients? If so, it would open new horizons in terms of secondary prevention of myocardial infarction.
