Article Abstract

The onset of precordial pain was assessed in all the patients admitted to the Clinical Hospital "Firule" and the Military Hospital, Split, during a six-year period (1981-1986) with acute myocardial infarction (n = 1304). According to the time of onset, all the subjects were stratified in three-hour intervals. The large majority of initial symptoms was registered between 7 and 10 a.m. (372 or 28.53% of all; chi 2 = 317, P less than 0.001). The results of this and other studies of circadian rhythm in coronary events points out to the high risk of morning hours, suggesting specific preventive measures, including pharmacological and life-style interventions.

The chronotype, the personal predisposition towards morning or evening activities, significantly influences health conditions, sleep, and eating regulations. Individuals with evening chronotypes are often at a higher risk for weight gain due to misalignment between their natural tendencies of functioning and social schedules, resulting in insufficient sleep, disruptions in eating habits, and decreased physical activity levels. Often, impaired glucose tolerance and changes in melatonin, adiponectin, and leptin secretion, along with alterations in the clock gene functions in subjects with evening preferences, may be predisposed to obesity.
