In practice<br />

Based on all these experimental and<br />

clinical findings, what approach should be<br />

adopted regarding the use of NRT in<br />

patients with coronary heart disease?<br />

In France, given the efficacy of NRT in<br />

smoking cessation and the fact that the<br />

experimental and clinical studies available<br />

at the time demonstrated its safety, the<br />

AFSSAPS (French Health Pro<strong>du</strong>cts Safety<br />

Agency) issued the following guidelines in<br />

May 2003 (27-28):<br />

- <strong>Nicotine</strong> <strong>replacement</strong> therapies are<br />

well tolerated by patients with coronary<br />

artery disease and do not exacerbate<br />

coronary heart disease or arrhythmias<br />

(level 2).<br />

- <strong>Nicotine</strong> <strong>replacement</strong> therapies are<br />

recommended in smokers with coronary<br />

artery disease (Grade B).<br />

- <strong>Nicotine</strong> <strong>replacement</strong> <strong>therapy</strong> can be<br />

prescribed as soon as the patient is<br />

discharged from the intensive care unit<br />

immediately after myocardial infarction<br />

(Grade C).<br />

- However, the prescribing physician<br />

must consider the loss of nicotine<br />

tolerance if the patient has not recently<br />

smoked (consensus agreement).<br />

Early prescription of NRT right from<br />

hospital admission is an important<br />

component of successful cessation after<br />

myocardial infarction. Indeed, studies<br />

show that half of patients who were<br />

smokers at the time of their infarct resume<br />

smoking within six months of the event,<br />

and usually relapse <strong>du</strong>ring the early weeks<br />

(29). Delaying the prescription of NRT<br />

therefore increases the risk of relapse.<br />

Furthermore, patients lose their nicotine<br />

tolerance and may not tolerate NRT so<br />

well.<br />

Prescribing NRT early after a coronary<br />

event therefore appears free of risk and<br />

guarantees better tolerance and better<br />

long-term results.<br />

To summarize<br />

• Media reports of rare clinical cases<br />

of cardiovascular events occurring in<br />

patients treated with nicotine<br />

<strong>replacement</strong> <strong>therapy</strong> (NRT) worried the<br />

population for a long time and led doctors<br />

to be cautious and to avoid prescribing<br />

NRT for cardiovascular patients.<br />

• In fact, the experimental studies<br />

have shown that NRT has no effect on<br />

thrombosis, probably has none on<br />

endothelial function and its potential<br />

sympathomimetic effects are highly<br />

attenuated <strong>du</strong>e to the pharmacokinetics<br />

of NRT and the nicotine tolerance<br />

acquired by smokers.<br />

• Moreover, the clinical studies show<br />

no excess of cardiovascular events with<br />

NRT in either the general population of<br />

smokers or in patients with stable<br />

coronary artery disease.<br />

• Although we have no randomized<br />

studies on the use of NRT immediately<br />

after an acute coronary syndrome, the<br />

absolute risk of using NRT in this situation<br />

is most probably much lower than the risk<br />

of continuing to smoke.<br />

• Taken together, these data have led<br />

to the use of NRT in smokers with<br />

coronary artery disease being<br />

recommended, including immediately<br />

after an acute coronary event such as<br />

myocardial infarction. ■<br />
