When measured with older generation assays, elevated troponin levels can be detected 6-12 hours after onset of myocardial injury, peaking at about 24 hours, followed by a gradual decline over several days (up to 2 weeks).he troponins are specific to cardiac muscle, rise fairly early in cardiac injury, and stay elevated longer than some of the other cardiac biomarkers such as CK-MB and myoglobin. Normal serial troponin values effectively rule out acute myocardial ischemia.
Beyond its short-term effects, inadequate sleep affects overall health in a number of ways. Diabetes, cardiovascular disease, hypertension, obesity, and depression have all been linked to inadequate sleep. Obesity
Ever since Vogel's studies in the 1970s it has been known that acute sleep deprivation, particularly deprivation of REM sleep, produces a positive effect on people with depression. The extremely depressed person feels much better if he goes without REM sleep for a night or two.
