Temporal variations in the incidence of acute myocardial infarction (AMI) have been described. However, AMI occurrence and biorhythm theory, which proposes the existence of three endogenous independent infradian cycles and AMI occurrence, has not been well studied. The purpose of this study is to determine whether specific days in the biorhythm cycles are related to AMI incidence.
Patients (40-85 years old) admitted for AMI at the Sherbrooke University Hospital Center, 1993-2008 were subjects of this study. Potential vulnerable days and performance days of the biorhythm cycles were calculated using birth and admission dates from the warehouse database. Observed AMI frequencies were compared to those expected using χ² tests.
There were 11,395 admissions for AMI. No relation was noted between single, double, or triple critical or noncritical days and AMI (χ² = 3.78; p > 0.05). Observed and expected AMI frequencies for maximal and minimal performance days were similar (χ² = 15.06; p > 0.05).
We found no evidence for a possible relationship between the date of AMI and critical maximum and minimum performance days of an individual's physical, emotional, or intellectual biorhythm cycles. We conclude that biorhythm theory does not predict admission for AMI.
已经描述了急性心肌梗死（AMI）发病率的时间变化。然而，AMI 的发生与生物节律理论（该理论提出存在三个内在的独立亚日周期和 AMI 的发生）尚未得到很好的研究。本研究的目的是确定生物节律周期中的特定日子是否与 AMI 的发生有关。
本研究的对象是 1993 年至 2008 年在舍布鲁克大学医院中心因 AMI 入院的患者（40-85 岁）。使用仓库数据库中的出生日期和入院日期计算生物节律周期的潜在脆弱日和表现日。使用 χ²检验比较观察到的 AMI 频率与预期频率。
共 11395 例 AMI 入院。单个、双个或三个关键或非关键日与 AMI 之间无关联（χ² = 3.78；p > 0.05）。最大和最小表现日的观察和预期 AMI 频率相似（χ² = 15.06；p > 0.05）。
我们没有发现 AMI 日期与个体的生理、情感或智力生物节律周期的关键最大和最小表现日之间可能存在关系的证据。我们得出结论，生物节律理论不能预测 AMI 的入院。
