The study is completely digital. Men and women who recently had an MI will be invited through a written brochure that will be present in all Norwegian departments of cardiology. Post-MI patients can check the investigators web site (www.sefh.no) to determine whether they are eligible for the study. After consent and answering the baseline questionnaire, each participant will be randomized to either the intervention or control group.

Control group: Standard surveillance after MI (no specific focus on sexual activity and functioning) Intervention group: Online sexual counselling including a short information film.

In order to assess the generalizability of the results, we will compare the age, sex and MI treatment of the respondents with data on Norwegian MI-patients in general.

The investigators will include 600 women and 600 men within 4 weeks after an acute MI. The investigators will invite the same number of women and men from the general population, invited through mass and social media.

All participants will be provided the same questionnaire at 4 weeks. Then outcome data will be obtained by a follow-up quest after 6 and 12 months.

The intervention is a film with the following main message:

• Sexual activity after MI does not increase risk of recurrence or death
• Sexual activity is associated with improved outcome after MI
• Resuming sexual activity as normal is recommended and completely safe
