specificity

TheAmericanCollegeofCardiology /American Heart Association (ACC/AHA) guideline update for exercise testing in a summary of studies from chest pain centres quotes sensitivity values of 29% 73% and 90% and specificity values of 99.4% 74% and 50% respectively for exercise testing10 with the European Society of Cardiology (ESC) guidelines for stable angina pectoris mentioning the reported sensitivity and specificity of exercise stress testing between 23 100% (mean 68%) and 17 100% (mean 77%) respectively2 but other studies mention low positive predictive value (PPV) of exercise testing in female patients and less likelihood of CAD in women who had a positive ETT.

"Understanding energy use and production in biological systems forms the metabolic basis for the concept of specificity of exercise and training.

The specificity of exercise principle indicates that each one of these categories of stretching may be used effectively and safely for specific people at a particular stage of training to achieve optimal stability or mobility.

This study shows, once again, the specificity of exercise prescription.

The American College of Cardiology (ACC) and the American Heart Association concluded that the diagnosis of CAD in women presents difficulties not experienced with men, due primarily to the lower sensitivity and specificity of exercise treadmill testing.
