Risk factor analysis of troponin-negative chest-pain patients who underwent cardiac catheterization.
OBJECTIVE
The purpose of this study is to identify risk factors in chest-pain patients with negative troponins who underwent cardiac catheterization after a positive myocardial perfusion imaging study.


BACKGROUND
Stress testing is beneficial to providing a prognosis for patients with known CAD. This study intends to identify pretest risk factors that will give the least number of false positive nuclear stress test results.


RESULTS
60% of patients who had a positive stress test had significant coronary artery disease on angiogram. History of CAD (P = .0017), HTN (P = .047) and age > 60 years (P = .0325) are significantly correlated with a positive angiogram.


CONCLUSIONS
History of CAD, HTN and age > 60 years were significantly associated with positive angiogram in troponin-negative chest-pain patients who underwent cardiac catheterization after a positive myocardial perfusion imaging study.
