Significance of the treadmill scores and high-risk criteria for exercise testing in non-high-risk patients with unstable angina and an intermediate Duke treadmill score.

Background: The appropriate management of patients with an intermediate Duke treadmill score (DTS) is not well established.The aim of this study is to compare several treadmill indexes (American College of Cardiology/American Heart Association (ACC/AHA) High-Risk Criteria for exercise testing,Veterans Affairs and West Virginia Prognostic Score, ST/Heart Rate Index, Failure to attain 85% of age-predicted maximum Heart Rate) with ST-segment depression in detecting significant or severe coronary artery disease as determined by coronary angiography in patients with an intermediate DTS.

Methods: 144 consecutive patients admitted to the hospital for unstable angina were studied.

Angiographic correlates of the treadmill scores in non-high-risk patients with unstable angina.

Background: There has been no clear consensus regarding the optimum definition of a high-risk exercise ECG test. The aim of this study is to compare the diagnostic accuracy of several treadmill scores [American College of Cardiology/American Heart Association (ACC/AHA) High-Risk Criteria for exercise testing, Duke Treadmill Score, Veterans Affairs and West Virginia Prognostic Score, ST/Heart Rate Index] with the ST-segment depression analysis in the detection of significant and severe coronary disease as determined by coronary angiography.

Methods: The study included a cohort of 248 consecutive patients admitted to hospital for unstable angina.

[Angiographic evaluation of high-risk treadmill scores in patients with unstable angina according to sex, age, or use of drugs with a negative chronotropic effect].

Introduction And Objectives: The aim of the study is to determine whether age, sex, or the use of drugs with a negative chronotropic effect modifies the sensitivity, specificity, positive or negative predictive value, or positive or negative likelihood ratio of the high-risk criteria used in exercise testing as defined by the Spanish Society of Cardiology (SEC) and the American College of Cardiology/American Heart Association (ACC/AHA), the Duke treadmill score, the Veterans Affairs and West Virginia prognostic score, or the ST/Heart Rate Index at the time when left main coronary artery disease, three-vessel disease or two-vessel disease involving the proximal left anterior descending artery is detected by coronary angiography.

Methods: The study included a cohort of 469 consecutive patients aged 75 years who were admitted to hospital for unstable angina. All patients underwent exercise stress testing and coronary angiography.
