Objective: To assess whether patients’ sexual activity has worsened after suffering an Acute Coronary Syndrome (ACS). To know whether to consider sex important and to have an active sexual life has any influence on the demand for sexual counselling after the episode. Design and Method: The sample consisted of men aged <76 with diagnosis of ACS episode, from September 1st 2014 to August 31st 2015, within the area of The University Health Care Hospital Complex of Palencia. They were appointed by a telephone call to hold a personal interview in which they answered an inquiry ad hoc and the validated Beck´s Depression Questionnaire and Sexual Desire and Aversion to Sex (DESEA) Questionnaire. Data were analyzed using the statistical program SPSS Statistics 20.0. Results: Only 30.8% of patients in our sample received sexual counselling after an ACS and 86.5% of those considered it insufficient. After an assessment using non-parametric test for dependent samples and U-Mann-Whitney, we noticed that sexual activity after an ACS has worsened and the fact that those patients consider sex important or have an active sexual life doesn’t significantly influence their request for sexual advice. Conclusions: Very few patients have received sexual counselling after an ACS and most of them require more. In our sample of patients, we may guess that this demand could be due to the fact that a significant number of them no longer have a sexually active life. But, considering sex important or having an active sexual life doesn’t have any influence on that demand.
