Study of Biomarkers in the Long-term Impact of Coronavirus Infection in the Cardiorespiratory System (PostCOVID19)

The aim of this study is to investigate the predictive role of cardiac biomarkers and significant pulmonary complications for late infection complications COVID-19 coronavirus on the heart and lung in patients treated with hydroxychloroquine / combination therapy azithromycin.

COVID-19 positive test patients will be divided into two groups according to therapeutic conduct. So, with a case-control distribution respecting age and sex, the two patient groups will be defined as "arm" with therapy (study population) and "Arm" without therapy (population control). This study is prospective and consists of three times:

1) T0- Moment of inclusion of the patient in the study, which coincides with the collection of clinical data and laboratory tests.

(2) T3- In the 3rd month after inclusion in the study, the patient will make a medical visit where data new laboratory tests will be acquired.

(3) T12- In the 12th month after inclusion in the study, the patient will make another medical visit where data clinical data will be obtained. Laboratory tests, which were altered during visit T3 will be repeated.

COVID-19 coronavirus patients undergoing therapy combined hydroxychloroquine / azithromycin will be compared to patients not undergoing this therapy. The comparison will be performed by analyzing the relationships between (1) troponin levels ultrasensitive cardiac data collected at the beginning of the infection and data of cardiac magnetic resonances in the 3rd and 12th month of collection troponins and (2) acute tomographic findings and the results the ergospirometers tests performed in those same periods.

In our understanding of COVID-19, its diagnosis, prevention and treatment are evolving quickly. As the disease spreads and new evidence emerges, it would be prudent to identify risk factors for the development of late cardiorespiratory complications in patients survivors of serious COVID-19 infections.

This prospective study of patients with COVID-19, involving a systematic record of clinical-laboratory variables and chronic cardiorespiratory complications, will be beneficial for the development of a risk model for these complications and to identify and / or predict the response to various treatment modalities.
