Impact of Integrative Cardiopulmonary Exercise Testing (13)
More recently, Olsen et al found that exercise Vo2 during submaximal work was a predictor of successful lung resection because it reflected the effects of cardiac function and oxygen transport. buy yasmin online
It remains to be seen whether integrative cardiopulmonary exercise testing will play a major role in either (1) patients undergoing nonthoracic surgery or (2) patients with non-heart or lung disease operative risks. Because studies of preoperative integrative cardiopulmonary exercise testing have focused on the current status of each patient, another question would be whether demonstrable, objective improvement in exercise capacity due to treatment intervention would also translate into reduced operative and postoperative risks.
2. Exercise Testing in Evaluation of Specific Diseases
Postmyocardial infarction: Exercise testing has prognostic value in postmyocardial infarction patients. For example, Theroux et al found that 84 percent of post-MI patients with ST depression or chest pain during exercise had complications over the next year (positive predictive value), whereas 54 percent of those with a negative test were free of complications (negative predictive value).
