【Abstract】 Objective To explore the feasibility and safety of primary coronary stenting in the patients with coronary heart disease Methods From march 1997 to august 1999, 80 cases with 90 of lesions were selected for primary coronary stenting without the predilation procedure Their efficacy and success rate were analysed Results We smoothly pushed 85 stents into the lesion in the 80 patients, the success rate of primary coronary stenting was 94% with shorter duration of the procedure and lower cost In 3 lesions the stent did not cross the lesion and was successfully retrieved in the guiding catheter, in 1 cases the stent was lost in the systemic circulation with no further complications Conclusions Primary coronary stenting without predilation was safe and feasible in selected patients更多还原
