[Behavior of ACTH and cortisol in acute myocardial infarct]
Insights
The study tracked adrenocorticotropic hormone (ACTH) and cortisol levels in acute myocardial infarction patients. Prolonged elevation of these hormones indicates a poorer prognosis, while normal levels suggest uncomplicated recovery.
Area of Science:
- Endocrinology
- Cardiology
Context:
- Acute myocardial infarction (AMI) is a critical cardiovascular event.
- The body's stress response, involving the hypothalamic-pituitary-adrenal (HPA) axis, is activated during AMI.
Purpose:
- To investigate the temporal patterns of adrenocorticotropic hormone (ACTH) and cortisol in patients with AMI.
- To correlate these hormonal patterns with the severity and outcome of AMI.
Summary:
- Thirty AMI patients were monitored for ACTH and cortisol plasma levels up to 60 hours post-infarction.
- Three distinct hormonal profiles emerged: normal levels, transient ACTH increase with sustained cortisol elevation, and persistently elevated ACTH and cortisol.
- Elevated ACTH and cortisol correlated with increased creatine kinase and suggested a more severe AMI course.
Impact:
- Findings suggest that the HPA axis response varies among AMI patients.
- Sustained elevation of ACTH and cortisol may serve as an unfavorable prognostic marker in AMI.
- Understanding these hormonal dynamics can aid in assessing AMI severity and patient outcomes.
Abstract:
In 30 patients with acute myocardial infarction in 4-hour intervals the temporary course of the ACTH and cortisol in the plasma was pursued up to the 60th hour. Here 3 different patterns of behaviour were found. In group 1 (11 patients) normal ACTH and cortisol values are present during the period of examination. In group 2 (13 patients) ACTH in increased at admission to hospital, and a decrease of the values to the normal takes place after the beginning of the infarction within 4 to 8 hours, whereas the plasma cortisol remains clearly increased. Increased ACTH and cortisol values during the whole period were measured in group 3 (6 patients). The different hormone constellations found are possibly the expression of a different reaction behaviour of the adrenocortical system in acute myocardial infarction. There is a weak positive correlation between the creatine kinase and the plasma cortisol. The size and the duration of the increase of ACTH and cortisol seems to be connected with the degree of severity of the acute myocardial infarction. An increase of ACTH and cortisol for a longer time is to be regarded as unfavourable for the course of the acute myocardial infarction, while uncomplicated courses are connected with normal ACTH and cortisol in the plasma.
