Scientists from the Karolinska Institute analyzed the health data of 29,226 people who survived a myocardial infarction, and came to the conclusion: those who were divorced had a higher risk of recurrent heart attack than those who were married and married. Other important factors were the level of income and education. The results of the work are published in the European Journal of Preventive Cardiology.
Many studies confirm that marriage is really good for health. It increases the chances of survival after heart surgery and reduces the risk of developing dementia.
The authors studied the data of the Swedish cardiology online registry Swedeheart. It contains information about all Swedes hospitalized with acute coronary syndrome, a condition that occurs with the development of coronary heart disease or before a heart attack. The new study included data on 29,226 patients aged 40 to 76 years who lived at least a year after the first heart attack. Myocardial infarction is more common in men, women made up 27% of the study participants. By marital status, people were divided into married and married, widowers and widows, divorced, as well as those who have never been married. The socio-economic situation was also taken into account: wealth and level of education.
Divorce, low incomes and lack of complete education significantly increased the likelihood of a second heart attack. Divorced people had an 18% higher risk than married people. Widowed Swedes and those who did not marry faced a slightly higher probability of recurrence of a heart attack than married and married, but the difference was insignificant. Those who studied for more than 12 years had a 14% lower risk than those who studied for less than nine years. As expected, low incomes also had a negative impact on health. The most affluent Swedes had an average 35% lower chance of a second heart attack than their least affluent fellow citizens.
The researchers concluded that marriage and socio-economic status can really affect the likelihood of a recurrence of the pathology. In their opinion, attending physicians should take these factors into account when planning therapy regimens.
