Exacerbations of chronic obstructive pulmonary disease (COPD) have a profound effect on the patient's health status and decline in lung function; they also impose a significant burden on healthcare resource utilization. Prevention and treatment of exacerbations is listed by the Global Initiative for Chronic Obstructive Lung Disease (GOLD) as among the major objectives of COPD management, and it is therefore an important outcome measure when studying any new agent. This article discusses pharmacologic therapy and other measures for preventing exacerbations and hospitalizations due to exacerbations of COPD.

To evaluate the effect of baseline cardiac troponin T measurements on in-hospital and long-term outcomes in patients with unstable angina/non-ST-segment elevation myocardial infarction who are treated with an early invasive strategy. ⋯ Troponin T remains a strong predictor of mortality, even at low levels, in patients with unstable angina/non-ST-segment elevation myocardial infarction who are treated with early revascularization. The risk associated with elevated levels is linear for death but not for myocardial infarction.

To compare the contributions of fitness level and physical activity patterns to all-cause mortality. ⋯ Exercise capacity determined from exercise testing and energy expenditure from weekly activity outperform other clinical and exercise test variables in predicting all-cause mortality.
