Adverse effect of smoking on the hyperaemic response in diabetic patients and control subjects.
In order to determine whether smoking had an adverse effect on the hyperaemic response, as measured by transcutaneous oximetry, matched groups of insulin-dependent diabetic smokers and non-smokers were compared both with each other and with similar matched groups of non-diabetic control subjects. The hyperaemic response was also measured immediately, 1 hour and 24 hours after smoking a cigarette in five control subjects who smoked. The hyperaemic response was significantly lower in the diabetic smokers compared with the diabetic non-smokers (p = 0.008) and in the control smokers compared with the control non-smokers (p = 0.011). No other significant differences were found. In the five subjects studied at intervals after smoking the responses were variable and inconsistent. Smoking modifies the hyperaemic response and this must be taken into account in any investigation using such measurements.
