Lunar phases and their connections with acute myocardial infarction (AMI) and hemorrheological character (HCh) are studied with the lunar calendar (LC) instead of the solar calendar. AMI onset is maximal on the lst day of the LC month, decreasing with an obvious trough around the 15th day. After the 15th day, occurrence increases gradually. The end and beginning of the lunar months show sharp peaks of AMI incidence. This study shows also that HCh variations have similar LC monthly rhythms. Our investigation demonstrates the correctness of traditional Chinese medical theory. This monthly rhythm forecasts the onset of AMI peaks and contributes to the secondary prevention of coronary heart disease (CHD).
