The work focused on a population of people over 35 years, making the data available, from 1993 to 2002, from the registration of stroke in Finland and includes all cardiac events with or without subsequent death or cardiac syndromes (ACS) .

During the study, which lasted 10 years, there were a total of 15,330 cardiac events, of which just over half, ended with the death of the patient within 28 days. Note that the number of cardiac procedures was approximately the same for men and women.

According to the results, the incidence of heart disease was approximately 60 percent higher among single men than married men, and approximately 63 percent higher among single women than married.

Single people, both men and women were also more likely to die within 28 days of having suffered a heart problem.

There are a number of factors that could explain the finding that being single is linked to an increased risk of stroke, according to researchers. Married people usually have better health habits, have more support and are better off financially than singles, all of which help to maintain your health.

Living in couple also allows healthcare faster and more frequent. In addition, patients can get married to hospital more quickly and be more "docile" when taking the medication prescribed to prevent angina pectoris or myocardial as aspirin or beta-blockers.

Previous studies have shown that being unmarried or living alone increased the risk of heart-related death and heart disease, but many of these studies have focused on male patients and data on women and older age groups are not present or did not have enough consistency.
