Introduction:

the health systems of most of the countries are facing the pandemic of the acute respiratory disease (COVID-19) caused by SARS-CoV-2 virus. It occurs in a more acute way in elder people and, above all, in those affected by other pathologies.

Objective:

to assess the effectiveness of an educational intervention at the level of knowledge of cardiopathic elder people on COVID-19.

Materials and methods:

a quasi-experimental, community-intervention type study without control group was carried out in cardiopathic elder people belonging to the Family Physician Office 1, of the polyclinic Francisco Rivero Arocha, of the Manzanillo municipality, province of Granma, in the period April-June 2020. We worked with a population of 108 elder people and a sample of 98 patients. Absolute and relative frequencies were worked out. The chi-square test was used for qualitative variables. To compare data before and after intervention, the McNemar test was used, with a significance level of 5 %.

Results:

female sex and patients aged 60-69 years. Hypertension and ischemic heart disease prevailed. Most of patients showed an inadequate level of knowledge on COVID-19 generalities, a fact that was reduced at the end. The adequate level of knowledge of cardiopathic elder people on epidemiology, clinical aspects and protection and self-care measures was increased.

Conclusions:

the educational intervention allowed modifying the knowledge of cardiopathic elder people on the novel coronavirus, but it is still necessary to work on the information of everything related to COVID-19.
