Objective: To assess whether to have a steady loving relationship changes sexual desire, level of depression and subjective need for sexual counselling to those patients who have suffered an Acute Coronary Syndrome (ACS) episode within the last year Design and Method: The sample consisted of males under 76, with a 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 at the local Health Center 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: 73% of patients in our sample had a partner. When applied non-parametric U-Mann-Whitney and Kruskal-Wallis as statistical contrast, it shows that loving relationships do not have any influence neither on patients’ sexual desire, nor on their demand for greater sexual counselling. It was also found that there is a direct correlation between the parameters of DESEA Questionnaire and de score reached on Beck’s Depression Questionnaire. And finally, that a decreased sexual desire will not influence their request for sexual advice. Conclusions: Sexual desire is a characteristic part of each person and that is confirmed in the participants of our research. Patients continued keeping interest for their sexuality after having suffer an ACS within the last year, regardless of the stability of their sexual relationships.
