The long-term cardiovascular impairment of COVID 19: need for clarity in definition and terminology.

Abstract

Clinical experience and several large studies in the field have found that SARS-CoV-2 infection can cause long-term persistent cardiovascular (CV) impairment beyond the acute phase of the disease. This has resulted in a major public health concern worldwide. Regarding COVID-related long-term involvement of various organs and systems, using specific definitions and terminology is crucial to point out time relationships, lingering damage, and outcome, mostly when symptoms and signs of CV disease persist beyond the acute phase. Due to a lack of a common standardized definition, investigators have used interchangeable terms such as "long COVID," "post-COVID," or "post-acute sequelae of COVID-19" to describe CV involvement, thus causing some confusion. For the sake of clarity, the aim of this paper is to discuss the definition and terminology used in defining sequelae after the acute phase of COVID-19, thus pointing out the meaning of definitions like acute cardiac injury, post-acute sequelae of COVID-19, long COVID syndrome, and increased risk of atherosclerotic cardiovascular disease.
