Heart attacks and strokes: most common at 6:30 a.m.

A recent study discovered that heart attacks and strokes most commonly occur at 6:30 a.m., according to The Daily Mail.

The newspaper reported Wednesday about a joint study conducted by Brigham and Women’s Hospital in Boston and Oregon Health and Science University.

The study involved checking the protein levels of 12 healthy adult volunteers for two weeks. Researchers specifically studied the protein plasminogen activator inhibitor-1, which slows the breakdown of blood clots, the causes of strokes and heart attacks, according to the report. The researchers were able to witness regular rhythms in the body’s level of PAI-1, which peaks at about 6:30 a.m.

“The findings of our research suggest that it is the internal body clock that contributes to the risk for cardiovascular events in the morning rather than (an) individual’s activities or environment,” Frank Scheer at Brigham and Women‘s Hospital was quoted as saying.

The researcher added that future research is required to test the possible links between the body clock and other illnesses such as obesity or diabetes.
