Brief Summary

The ICOPER study aims to analyze the structure, vascular function, vascular aging and determining factors in 300 adults diagnosed with Persistent Covid in the field of Primary Health Care.

Detailed Description

Objective: To analyze the structure, the vascular function, the vascular aging and the determining factors in adults with a diagnosis of Persistent Covid and the differences by gender.

Design: Cross-sectional descriptive observational study. Setting: The study will be carried out at the Salamanca Primary Care Research Unit (APISAL). Study Subjects: The study includes the basis of the Persistent Covid Monographic consultation in the Internal Medicine Service of the University Hospital of Salamanca and the subjects with the diagnosis of Persistent Covid in the MEDORA Primary Care clinical history. Thus, 300 subjects have been obtained who are diagnosed with Persistent Covid, who meet the diagnostic criteria established by the Spanish Society of General and Family Physicians and sign the informed consent.

Measurements: The variables reflected in the Integrated Assistance process for the Care of People Affected by SARS CoV-2 of the Junta de Castilla y León will be collected, to evaluate the functional status of the patient and persistent symptoms, their impact on activities of daily life and quality of life of patients with Persistent Covid and the perception of their health. Lifestyles (diet, physical activity, tobacco and alcohol), psychological factors and cognitive impairment will be collected using validated questionnaires, and physical activity will be objectively measured with a 7-day pedometer. Vascular structure and function will be analyzed by measuring the thickness of the carotid intima media (Sonosite Micromax); pulse wave analysis and carotid-femoral pulse wave velocity (VOPcf) (Sphygmocor System). Cardio Ankle Vascular Index (CAVI), ankle-brachial pulse wave velocity (VOPbt) and ankle-brachial index (Vasera VS-2000®). Vascular aging will be calculated using the 10 and 90 percentiles of the VOPcf and the VOPbt. Demographic, analytical variables and to assess retinal, cardiac, renal, cerebral vascular lesion and cardiovascular risk will be collected.
