[Clinical observation on effect of modified huanglian wendan decoction in treating diabetic asymptomatic myocardial ischemia].

OBJECTIVE

To investigate the clinical efficacy of modified huanglian wendan decoction (MHWD) on diabetic asymptomatic myocardial ischemia.

METHODS

Ninety patients were randomly divided into two groups. The control group (n=30) was given Xinkang tablet (XKT) at a dose of 20 mg, twice a day. The treated group (n=35) was given MHWD besides XKT as that given to the control group. The treatment course for both groups was 1 month. Indexes, including blood glucose, glycosylated hemoglobin, blood lipids, myocardial zymogram, hemorheologic parameters, urinary albumin, routine examination of blood and urine, function of liver and kidney, as well as 24h dynamic electrocardiogram and electrocardiogram exercise test were measured in the two groups before and after treatment.

RESULTS

The total clinical effective rate in the treated group and the control group was 88.33% and 56.67% respectively (P < 0.05), showing significant difference between them. The frequency of ischemia attacking, paroxysmal cumulative time, motion related incidence were lower in the treated group after treatment than those in the control group. Besides, in the treated group after treatment, the level of blood lipids and hemorheologic parameters were significantly improved (P < 0.05 or P < 0.01), hematocrit was unchanged and triglyceride, red blood cell agglutination index and erythrocyte deformability index were obviously different to those in the control group (P < 0.05). While in the control group after treatment, except the improving of whole blood viscosity (P < 0.05), no significant change was found in the other indices.

CONCLUSION

MHWD has effects in improving myocardial ischemia, bettering hemorheologic condition and reducing blood lipids.
