ABSTRACT

Objective To explore the clinical therapeutic effects of intravenous infusion of dihiazem in com-bination with metoprolol for treating aortic dissection. Method From June 2005 to January 2008, fourteen patients with aortic dissection (male 8, female 4) in the First Hospital of Yichang,were treated with diltiazen 1～5 μg/(kgrate 30 min,60 min, 120 min,6 h, 1 d and 7 d after treatment were recorded. All data were analyzed using self-matching t test. Results The heart rate reduced significantly 60 min after treatment. The heart rate reduced (21±5) beats/min from the baseline. The total effective rate was 100% .The blood pressure reduced significantly 30min after treatment. The systolic pressure reduced to (126.2±11.1 ) mmHg and diastolic pressure declined to (80.3±8.1) mmHg. No severe cardiac side-effect observed. Conclusions Dihiazem in combination with meto-prolol can reduce heart rate and blood pressure markedly and safely in aortic dissection patients.
