Health Outcome Predictive Evaluation for COVID 19 international registry (HOPE COVID-19), rationale and design
The disease produced by the new coronavirus known as SARS-CoV-2 (Severe Acute Respiratory Syndrome Coronavirus 2), named COVID-19 (Coronavirus Disease-2019) has recently been classified as a pandemic by the World Health Organization (WHO). However, scarce clinical data is available and generally limited to the Chinese population due to the first cases were identified in Wuhan (Hubei, China).This article describes the rationale and design of the HOPE COVID-19 (Health Outcome Predictive Evaluation for COVID 19) registry (ClinicalTrials.gov Identifier: NCT04334291). With an ambispective cohort design, eligible patients are those discharged, deceased or alive, from any hospital center with a confirmed diagnosis or a COVID-19 high suspicion. With a current recruitment of more than 7000 cases, in 46 hospitals in 8 countries, since it is not possible to estimate the sample size based on literature reports, the investigators will try to get the maximum numbers of patients possible. The study primary objective is all cause mortality and aims to characterize the clinical profile of patients infected in order to develop a prognostic clinical score allowing, rapid logistic decision making. As secondary objectives, the analysis of other clinical events, the risk-adjusted influence of treatments and previous comorbidities of patients infected with the disease will be performed.The results of HOPE COVID-19 will contribute to a better understanding of this condition. We aim to describe the management of this condition as well as the outcomes in relation to the therapy chosen, in order to gain insight into improving patient care in the coming months. Clinical Trial registration: ClinicalTrials.gov. Unique identifier: NCT04334291
Quantitative flow ratio as a new tool for angiography-based physiological evaluation of coronary artery disease: a review
none16The functional evaluation of coronary stenoses has obtained important clinical results in recent years, resulting in strong guideline recommendations. Nonetheless, the use of coronary wire-based functional evaluation has not yet become part of the routine in catheterization laboratories for several reasons, including the need to advance a wire into the coronary vessel to interrogate the stenosis. Angiography-derived indexes have been introduced to expand the current use of physiology to estimate the functional meaning of a stenosis on the basis of angiographic data only. The most studied and validated angiography-derived index is certainly the quantitative flow ratio. This article will summarize the basics of the quantitative flow ratio, the related validation studies and its current and future applications.noneCerrato E.; Mejia-Renteria H.; Franze A.; Quadri G.; Belliggiano D.; Biscaglia S.; Lo Savio L.; Spataro F.; Erriquez A.; Giacobbe F.; Vergara-Uzcategui C.; Di Girolamo D.; Tebaldi M.; Varbella F.; Campo G.; Escaned J.Cerrato, E.; Mejia-Renteria, H.; Franze, A.; Quadri, G.; Belliggiano, D.; Biscaglia, S.; Lo Savio, L.; Spataro, F.; Erriquez, A.; Giacobbe, F.; Vergara-Uzcategui, C.; Di Girolamo, D.; Tebaldi, M.; Varbella, F.; Campo, G.; Escaned, J
