Clusters of&nbsp;Survivors of COVID-19 Associated&nbsp;Acute Respiratory Failure According&nbsp;to Response to Exercise. <em>Int. J.&nbsp;Environ. Res. Public Health</em> 2021, 18,&nbsp;11868.</p> <p><strong>Abstract</strong>: COVID-19 survivors are associated with acute respiratory failure (ARF) and show a high&nbsp;prevalence of impairment in physical performance. The present studied aimed to assess whether we&nbsp;may cluster these individuals according to an exercise test. The presented study is a retrospective&nbsp;analysis of 154 survivors who were admitted to two hospitals of Istituti Clinici Scientifici Maugeri&nbsp;network, Italy. Clinical characteristics, walked distance, heart rate (HR), pulse oximetry (SpO2),&nbsp;dyspnoea, and leg fatigue (Borg scale: Borg-D and Borg-F, respectively) while performing the sixminute&nbsp;walking distance (6MWT) were entered into unsupervised clustering analysis. Multivariate&nbsp;linear regression identified variables that were informative for the set of variables used for cluster&nbsp;definition. Cluster 1 (C1: 86.4% of participants) and Cluster 2 (C2: 13.6%) were identified. Compared&nbsp;to C1, the individuals in C2 were significantly older, showed significantly higher increase in fatigue&nbsp;and in dyspnoea, greater reduction in SpO2, and a lower HRpeak during the test. The need of walking&nbsp;aids, time from admission to acute care hospitals, age, body mass index, endotracheal intubation,&nbsp;baseline HR and baseline Borg-D, and exercise-induced SpO2 change were significantly associated<br> with the variables that were used for cluster definition. Different characteristics and physiological&nbsp;parameters during the 6MWT characterise survivors of COVID-19-associated ARF. These results may&nbsp;help in the management of the long-term effects of the disease.</p>
