A study carried out by Rhode Island Hospital, in the U.S., revealed that surgery, especially that to correct acute aortic dissection, tends to result in a lower death rate when the Moon is waning.
The research was carried out to establish the effect of natural time variations on survival rates and length of hospital stay following heart surgery.
â€˜While there has been previous research on the seasonal impacts of cardiovascular disease, there has not been any data about the effect of the lunar cycles on cardiac cases, until now,â€™ said senior author Dr Frank Sellke.
He added: â€˜We focused the study on patients having aortic dissection and found that the odds of dying following this procedure were greatly reduced during the waning full moon, and that length of stay was also reduced during the full moon.â€™
Aortic dissection occurs when there is a tear in the lining of the aorta. This tear allows a column of blood to enter the aortic wall forcing the layers apart.
