Clinical effect analysis of patient with coronary heart disease after coronary intervention therapy

To explore the effectiveness and safety of the patients with coronary heart disease after coronary intervention therapy. 140 patients with coronary heart disease hospitalized and randomly divide them into observation group and control group with 70 patients respectively. Give coronary intervention therapy to the 70 patients in the observation group, and give drug therapy to the 70 patients in the control group. Compare the overall effective rate, survival rate and occurrence probability of complications of the two groups. The overall effective rate of patients in observation group reaches 92.86%, while the rate of patients in the control group only reaches 81.43%. Through data comparison of these two groups, it is found that the overall effective rate of the control group is far less than that of the observation group, so does the survival rate within 1 year; the differences between the two groups are statistically significant (P<0.05). although the occurrence probability of complications of the observation group is less than that of the control group, their difference is not statistically significant (P>0.05). The effect of coronary intervention therapy for patient with coronary heart disease is better than the effect of drug therapy, and both therapies have equivalent safety.
