A bad marriage could really cause broken heart

A bad marriage really could lead to a broken heart, new research looking at how marriage quality affects cardiovascular health suggests. A study by US researchers found older couples who are in an unhappy marriage have a higher risk of heart disease than those in a happy marriage. 

According to a  team at Michigan State University and the University of Chicago ,the risk is greatest for married women aged between 70 and 80-years-old. The team analysed five years of data from 1,200 married men and women who participated the National Social Life, Health and Aging Project. The participants were aged between 57 and 85-years-old at the beginning of the project. Source
