Title: The relationship between myocardial blood supply and coronary artery stenosis in different gender patients with ischemia change in stress electrocardialgram
Abstract: Objective:Investigating the interrelation and clinical value between coronary artery stenosis and myocardial blood supply in different gender patients with ischemia change in adenosine stress electrocardialgram. Methods: Analyzing 7 826 patients data retrospectively with adenosine stress /rest myocardial perfusion imaging( MPI) imaging from May. 2008 to November. 2012 because of suspecting CAD including 104 patients with ischemia change in ECG during adenosine stress test. As the research objects,in these patients male /female= 24 /80,mean age( 58. 76 ± 9. 97),including 62 petients underwent coronary artery angiography( CAG) in one month. Results: The ST segment horizontally or inclined moved down ≥0. 1mv in adenosine stress test ECG comparing rest ECG in 104 patients,and the subsequent MPI showed: 66 positive( male /female = 18 /48),38negtive( male /female = 6 /32,P = 0. 181). 33 positive patients in MPI( male /female = 14 /19) undergone CAG with showing : there was no obvious coronary artery stenosis in only 1 female patient,and other 32( 97. 0%,32 /33) ones got more than one coronary artery stenosis with the extent ≥50%( male 14 /14 = 100%,female 18 /19= 94. 7%,P = 0. 576). 29 negtive patients( male /female = 4 /25) undergone CAG with showing : there was no obvious coronary artery stenosis in 2 male( 50%,2 /4) and 24 female patients( 96%,24 /25),other 2 male( 50%,2/4) and 1 female( 4%,1/25) patients got three-vessel coronary artery disease with the extent ≥50%( P =0.042). Conclusion: In the patients with ischemia change in adenosine stress electrocardialgram,there is no relevance in the incidence rate of positive and negative in MPI with gender,and so as the incidence rate between the positive in MPI and serious coronary artery stenosis. But in negative MPI patients,the incidence rate of serious coronary artery stenosis in the male is obviously higher than the female,which reminds us to take more care of such male patients for clinical diagnosis and evaluation,even taking CAG if necessary.
