Difference in mobilization of progenitor cells after myocardial infarction in smoking versus non-smoking patients: insights from the BONAMI trial

Table 1 Baseline characteristics of the BONAMI patients, according to smoking status

Clinical parameters and risk factors	Total (number = 101)	Non-smokers and former smokers (number = 47)	Active smokers at admission^a(number = 54)	P-value^b

Body mass index (kg/m²), mean ± SD	25.7 ± 3.7	26.3 ± 3.1	25.1 ± 4.1	NS
Hypertension n (%)	35 (35)	23 (49)	12 (22)	0.01

Mean LVEF, % ± SD	38.9 ± 7.5	39.1 ± 7.7	38.9 ± 7.4	NS

^aactive smoking was evaluated at the time of admission to the hospital (day 0 of AMI). Other patients were non-smokers (patients who had never smoked) or former smokers (patients who had stopped smoking at least three months before study); ^bChi-2 test, t-test. LVEF, left ventricular ejection fraction; NS, not significant; SD, standard deviation.
