Abstract:
Objective To study the correlation between the abnormal perfusion area detected by resting+regadenoson stress D-SPECT and the severity of coronary arterial lesions.Methods One hundred patients needing coronary angiography and PCI admitted in the cardiology department of First Hospital of He-bei Medical University from April 1,2022 to April 1,2023 were selected as the study subjects.The resting+regadenoson loading examination was performed by using the special cardiac machine D-SPECT.The patients were divided into the mild ischemia group(range＜10％),moderate ischemia group(range 10％-20％)and severe ischemia group(range＞20％)according to the proportion of sparse or defect appearance in myocardi-al segmental radionuclide distribution during regadenoson stress D-SPECT in comparison with resting exami-nation.The coronary arterial angiography was performed.The Gensini score was calculated.Results The Gensini score in the severe ischemia group was(55.70±20.60)points,which was higher than(41.88±28.07)points in the moderate ischemia group and(39.71±21.40)points in the mild ischemia group,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the Gensini score between the mild ischemia group and moderate ischemia group(P＞0.05).The mean stent length in the severe ischemia group was(30.50±7.47)mm,which was significantly higher than(20.90±4.72)mm in the mild ischemia group and(23.50±3.87)mm in the moderate ischemia group,and the differ-ences were statistically significant(P＜0.05).There was no statistically significant difference in the mean stent length between the mild ischemia group and moderate ischemia group(P＞0.05).Conclusion The abnormal perfusion area detected by resting+regadenoson stress D-SPECT is conducive to evaluate the severity of coro-nary arterial lesions and the length of needing implantation stent.
