At the beginning of 2020, coronavirus disease 2019 (COVID-19) emerged as a new pandemic, leading to worldwide health crisis and overwhelming healthcare systems due high numbers hospital admissions, insufficient resources, lack standardized therapeutic protocols. Multiple genetic variants severe acute respiratory syndrome 2 (SARS-CoV-2) have been detected since its first public declaration in some them being considered concern (VOCs) corresponding several pandemic waves. Nevertheless, growing number COVID-19 patients are continuously discharged from hospitals, remaining symptomatic even months after their episode infection. Long or ‘post-acute syndrome’ characterized by variability clinical manifestations ranging cardiorespiratory neurological symptoms such chest pain, exertional dyspnoea cognitive disturbance psychological disturbances, e.g., depression, anxiety sleep with crucial impact on patients’ quality life. Moreover, COVID is viewed cardiovascular risk factor capable modifying trajectory current future diseases, altering prognosis. Therefore, this review we address definitions pathophysiology, focus manifestations. Furthermore, aim mechanisms chronic cardiac injury variety sequelae observed recovered patients, addition potential role clinics medical management condition. We will further research for better understanding actual directions.

Abstract Background Aneurysmal subarachnoid hemorrhage (aSAH) is a life-threatening neurosurgical emergency with high mortality rate. Delayed cerebral ischemia (DCI) and vasospasm (CVS) are delayed products of early brain injury (EBI), which may constitute the principal determinant an unfavorable patient prognosis. Consequently, mitigation DCI CVS assumes paramount significance in pursuit enhanced outcomes. However, except for oral nimodipine, there no effective therapy available current guideline. Hence, exigency arises to proffer novel treatment paradigms. The diversity hydrogen therapeutic targets has been largely reported basic research, unveiling its latent capacity ameliorate EBI aSAH patients. Methods Early H ydrogen– O xygen Gas M ixture I nhalation Patients Subarachnoid Hemorrhage (HOMA), single-center, prospective, open-labeled, randomized controlled clinical trial, endeavors evaluate efficacy safety hydrogen–oxygen gas mixture inhalation A cohort 206 patients will be either group (8 h per day, 3 L/min, concentration 67%, oxygen 33%) or within 72 after treated 7 days ICU ward. primary outcomes incidence during hospitalization.
