To address existing gaps in knowledge on CVD among European countries at different income
levels, a collaboration of outcomes-oriented researchers from the University of Bologna
partnered with Central and East European (CEE) countries researchers to conduct the
International Survey of Acute Coronary Syndromes in Transitional Countries (ISACS-TC)
investigating underlying threats in patients' CVD health status (NCT01218776).

In response to the COVID-19 crisis, ISACS-TC has promoted a new registry of the existing
and further centers of the same geographic areas to support clinical research to prevent,
and treat the COVID-19 illness. These efforts are made possible by the generous
contributions of clinical research volunteers in some of the countries participating to
the prior acute coronary syndrome network.

Scientific and clinical evidence is evolving on the effects of COVID-19, which can affect
multiple organ systems. As, so the COVID-19 pandemic underscores the urgent need for
coordination, collaboration, and information-sharing among researchers worldwide.
Researchers of many disciplines have, therefore, joined the ISACS-TC investigators to
build a multi-disciplinary registry investigating the impact of COVID-19.

Projects should be mainly focused on topics related to:

1. The impact of COVID-19 infection on patients who have attended any health care
center (within hospital beds), and who have been discharged or have died at the time
of the evaluation. The main objective of this task is to carefully characterize the
clinical profile of patients infected with COVID-19 in order to develop a simple
prognostic clinical score allowing rapid logistic decision making such as discharge
with follow-up, referral to provisional hospitals, or admission to hospital centers
with advanced equipment or specialized procedures and techniques. A secondary
objective of this retrospective analysis is to evaluate the risk-adjusted influence
of prior evidence-based treatments and comorbidities on patients infected with the
disease.

2. The second issue relates to the long-term health consequences after COVID-19
infection. Early reports suggest residual effects of SARS-CoV-2 infection, such as
fatigue, dyspnea, chest pain, cognitive disturbances, arthralgia, and decline in
quality of life. However, the evidence is still scarce. Prior studies did not take
into account the vast majority of patients with a mild course of the infection. As
well, the definition of the post-acute COVID-19 timeline is evolving. Today we may
summarize the post-acute COVID-19 syndrome into two categories:

- subacute or ongoing symptomatic COVID-19, which includes symptoms and
abnormalities present from 4-12 weeks beyond acute COVID-19;

- chronic or post-COVID-19 syndrome, which includes symptoms and abnormalities
persisting or present beyond 12 weeks of the onset of acute COVID-19 and not
attributable to alternative diagnoses. Systematic study of sequelae after
recovery from acute COVID-19 is needed to develop an evidence-based
multidisciplinary team approach for caring for these patients, and to inform
research priorities.

One trained physician will critically review the patients' reported symptoms and will
assess SARS-CoV-2 IgG at each visit. In addition, wherever needed, the investigators will
investigate the daily living status of survivors of COVID-19 using telephone interview
questionnaires including Activity Daily Living (ADL), Self-rating Depression Scale (SDS),
and New York Heart Association (NYHA) functional class.
