Can the Ergometric Test in Flu-like Syndrome Help in the Outcome Analysis of Unvaccinated Patients

During the flu-like syndrome, the cardiovascular risk is increased, especially in the elderly. Understanding whether blood pressure assessment during an exercise test can aid in the understanding of patient outcomes, thereby improving prognostic ability in clinical practice, is the focus of the present study. Therefore, the aim of this study is to evaluate the hemodynamic response of adults with flu-like symptoms, both vaccinated and unvaccinated, and to conduct a 30-day follow-up for assessment. Patients who are indicated for an ergometric test and present with flu-like syndrome will be selected. We will inquire about their vaccination history and perform the ergometric test to evaluate test duration, arrhythmias, and ischemias
