The comparative safety and diagnostic accuracy of adenosine myocardial perfusion imaging in women versus men.
OBJECTIVE
To determine if the diagnostic accuracy and safety of intravenous adenosine myocardial perfusion imaging is significantly different in men compared with women.


METHODS
Prospective, comparative, open-label clinical trial.


METHODS
Nuclear medicine laboratory in a university-affiliated hospital.


METHODS
Consecutive patients who were referred for evaluation of known or suspected coronary artery disease. Patients were judged not to be able to exercise adequately.


METHODS
Coronary angiography was conducted within 6 weeks of an adenosine thallium-201 myocardial perfusion imaging study.


RESULTS
Diagnostic accuracy is shown in the table. [table: see text] Overall, side effects from adenosine were not different between men and women. The frequencies of ST depression and chest pain were significantly greater in women than men, although their etiologies are unknown. The frequency of severe side effects such as heart block and hypotension was not different between men and women.


CONCLUSIONS
The diagnostic accuracy and safety of adenosine thallium-201 myocardial perfusion imaging are generally similar in women and men.
