Comparative study and clinical application of adenosine triphosphate stress and exercise stress myocardial perfusion imaging in diagnosis of coronary disease

Objective To explore diagnostic value of adenosine triphosphate stress myocardial perfusion imaging(ATP-MPI) to coronary artery disease(CAD).Methods ATP-MPI was made for 47 CAD patients and the contrast analysis was conducted among ATP-MPI,stress test myocardial perfusion imaging(STMPI) and coronary angiography(CAG).Results The detectable rate of ATP-MPI,ST-MPI and CAG were(78.7)%,(80.9)% and(85.1)%.There was no significant difference among them(χ~2=(0.638),P(0.05)).With CAG as the standard,the sensitivity and specificity of ATP-MPI and ST-MPI in CAD detection had no significance(P(0.05)).Conclusion Dignosis by ATP-MPI to CAD can replace ST-MPI as a routine examination.
