Abstract：Objective To analyze the respiratory and cardiovascular abnormalities of smokers without respiratory symptoms.Methods From January 2012 to July 2013 in the hospital, 152 cases of smokers without respiratory symptoms were selected as the observation group , 150 cases of healthy in the same period were selected as the control group , the respiratory and cardiovascular data of two groups were compared , the forced expiratory indicators ( FVC) , 1 second forced expiratory vol-ume ( FEV1 ) , one second ratio ( FEV1/FVC) , maximum minute ventilation ( MVV) , forced expiratory vital capacity of 50%of calls gas flow ( FEF50%) , 75%of vital capacity , forced expiratory flow ( FEF75%) were the respiratory index , the cardiovas-cular system indicators heart rate (HR), blood pressure (BP), whole blood viscosity (WBV), plasma viscosity (PV), whole blood reduced viscosity (WBRV), erythrocyte deformation index (TK), erythrocyte aggregation index (EAI) were the cardiovascular index .Results FEV1/FVC, MVV, FEF50%, and FEF75% in observation group were significantly lower than those in the control group , there was significant difference between the groups ( P <0.05);WBV, PV and WBRV of obser-vation group were significantly higher than those in the control group , there was statistical significance difference between the two groups ( P <0.05).Conclusion No respiratory symptoms smokers’ respiratory and cardiovascular systems are in abnor-mal state, pulmonary ventilation function and small airway function were decreased , the hemorheological parameters were sig-nificantly increased .
