The main goal is to develop a health online app based on a Mediterranean lifestyle score (diet, cooking preferences, rest, physical activity, social habits, conviviality) and its implementation in clinical settings with patients that have suffered from a cardiovascular event. This is a pilot study that will allow an integral assessment of health as an attempt to decrease obesity, one of the main risk factors of cardiovascular disease, as well as to improve the prevention of secondary events. The main goal involves the following specific objectives: Developing and transferring the previously validated questionnaire in Spanish population (MEDLIFE index, MEDiterranean LIFEstyle) to evaluate adherence to a Mediterranean lifestyle an online app, that allows: To evaluate and to monitor the adherence to the MEDLIFE throughout time. To use the MEDLIFE online app to obtain customized recommendations according to the results (an instantaneous generation of a resume of results). To start conversations between patient and health workers to improve patient's lifestyles, obesity or related parameters and cardiovascular health. To keep information in a safe way that will allow it to be linked to other health indicators. Conducting a qualitative study using personal interviews with health providers and patients, to evaluate acceptation, feasibility, barriers, or limitations when using the MEDLIFE app in clinical practice, aiming for the app's enhancing. Conducting a pilot study of implementation of MEDLIFE in clinical settings, in patients with a cardiovascular event (myocardial infarction, ictus, angina, ischemic cardiopathy) (n= 80-100, trying parity between men and women). This is the project's intervention part. To evaluate changes in MEDLIFE and its components, anthropometric and biochemical measurements between baseline, 3-month, 6-month and 8-month follow-up. Following participants by means of revision of medical reports and clinical histories to register future cardiovascular events (dynamic).
