[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.
