IJERPH, Vol. 18, Pages 676: Cortisol on Circadian Rhythm and Its Effect on Cardiovascular System International Journal of Environmental Research and Public Health doi: 10.3390/ijerph18020676 Authors: Nor Amira Syahira Mohd Azmi Norsham Juliana Sahar Azmani Nadia Mohd Effendy Izuddin Fahmy Abu Nur Islami Mohd Fahmi Teng Srijit Das The synthesis and secretion of cortisol are controlled by the hypothalamic–pituitary–adrenal axis. Cortisol exhibits a proper 24-h circadian rhythm that affects the brain, the autonomic nervous system, the heart, and the vasculature that prepares the cardiovascular system for optimal function during these anticipated behavioral cycles. A literature search was conducted using databases such as Google Scholar, PubMed, and Scopus. Relevant search terms included “circadian rhythm and cardiovascular”, “cortisol”, “cortisol and acute coronary syndrome”, “cortisol and arrhythmias”, “cortisol and sudden cardiac death”, “cortisol and stroke”, and “cardioprotective agents”. A total of 120 articles were obtained on the basis of the above search. Lower levels of cortisol were seen at the beginning of sleep, while there was a rise towards the end of sleep, with the highest level reached at the moment the individual wakes up...
