“…A medical history without previous syncopal episodes was found to be an additional predictive factor of APDs, a finding that shall be interpreted according to the evidence that recurrent syncope does not predict the risk of adverse outcomes [ 10 ], and is neither associated with the presence of structural heart disease [ 4 ]. A second peak of first-time incidence of syncope has been observed in the elderly, most likely attributable to age-related alterations of cardiovascular system and to other comorbidities, with high rate of underlying cardiac cause (of up to 34% of all cases) [ 4 , 11 ].…”

According to the 2018 ESC guidelines, emergency physicians shall primarily aim to identify syncopal episodes associated with an underlying acute principal disease. Therefore, in this study, we aimed to assess the incidence of syncope associated with acute principal diseases (APDs) and to identify predictive factors reflecting the presence of these underlying conditions. We retrospectively evaluated all patients presenting with syncope during a 6-month period to the local emergency department, collecting incidence of syncopal cases associated with APDs, personal information, clinical features, and laboratory abnormalities, which were compared between syncopal patients with or without APDs. A syncope-associated APD could be diagnosed in 346/1279 patients (27.1%). In the majority of cases, the cause was a non-cardiovascular acute condition (67%), mostly non-life-threatening such as infectious diseases (34.4%) and acute diseases with pain, fluid loss or hypotension (23.7%). Severe acute cardiovascular conditions were less frequent (4.2%). Cardiogenic syncope, no previous history of syncopal episodes, not full agreement with typical clinical features of syncope, alterations of vital parameters, and laboratory abnormalities were also found to be independently associated with syncope-associated APDs. Syncope may be frequently associated with APDs of varying severity, though mostly non-clinically threatening, thus confirming that this condition shall be considered a symptom and not a disease. Emergency physicians should hence be first engaged in troubleshooting an underlying pathology when facing patients with syncope, for timely identifying patients at higher risk of short-term adverse events and reducing inappropriate admissions and diagnostic investigations, especially in the presence of hypotensive syncope elicited by non-severe concurrent conditions.

“…Syncope means short-term loss of consciousness, which occurs suddenly, with loss of postural tone, resulting in spontaneous recovery and the return of previous neurological functions. 1 The typical presentation of the patient with syncope is a motionless and limp patient, hypotensive, pale, clammy, cold extremities and filiform pulse, and shallow breathing. In most cases syncope is a benign nature, however, with a certain number of syncope patients may indicate a serious, life-threatening condition.…”
