To clarify the relative contribution of resting haemodynamic profile and pulmonary function to exercise capacity in patients with heart failure. ⋯ The data confirm previous studies showing a poor correlation between resting indices of cardiac function and exercise capacity in heart failure. However, several pulmonary function variables were related to peak exercise VO(2). In particular, lung diffusing capacity and respiratory muscle function seem to affect exercise tolerance during heart failure.

To determine whether a new protocol, using a rapid and sensitive CK-MB(mass) assay and serial sampling, can rule out myocardial infarction in patients with chest pain and decrease their length of stay in the cardiac emergency room without increasing risk. ⋯ Using a rule-out myocardial infarction protocol with a rapid and sensitive CK-MB(mass) assay and serial sampling, the length of stay of patients with chest pain in the cardiac emergency room can be reduced without compromising safety.
