![]() Premonitory period may occur and includes dizziness, lightheadedness, Syncope occurs with a rapid onset and a spontaneous, complete, and typically prompt recovery. In patients with noncardiac or unknown cause of syncope, the followingĪre important prognostic factors of mortality: older age, male sex, and 5 Higher mortality rates are seen with syncope secondary to cardiac causes irrespective of age. Structural cardiac defects, cardiomyopathies, or congestive heartįailure (CHF) have a uniformly worse prognosis than other patient Patients with a history of myocardial infarction (MI), arrhythmia, 6,10 However, in older patients, categorically, 75% of syncope is attributed to noncardiac causes and 15% is due to cardiac causes. To the frequent presence of more than one potential cause. Of syncope with clarity in 40% to 60% of elderly patients, usually due Of note, it may not be possible to attribute a cause ( TABLE 2) 5 Syncope is the seventh most common reason for emergency department admission of adults over the age of 65. Polypharmacy, is an independent risk factor for both syncope and death. ![]() Vasomotor instability, autonomic failure, polyneuropathy, and use of 7,8 Advancing age, which correlates with increasingįrequency of coronary artery and myocardial disease, arrhythmia, Than 25 years of age, 10% to 15% have their first faint after 65 years While 60% of persons experience their first faint (syncope) at younger Syncope in seniors can be attributed to age-related neurohumoral and physiological changes in conjunction with medications ( TABLE 1) and comorbid chronic diseases, ultimately decreasing the delivery of cerebral oxygen via multiple mechanisms. 5 In some cases of syncope, pharmacotherapy is introduced to prevent complications and reduce morbidity. 4 Additional complications from recurrent falls can include lacerations and intracranial trauma. 3 Syncope often results in falls, and in older adults, a fracture secondary to a fall is more likely to ensue. Otherwise healthy people, it occurs more often in the elderly. While syncope affects all age groups and can occur in Repeatedly over time, resulting in limitation of activities such asĭriving. Some individuals have a single fainting episode, others may faint 1-3 Experiencing an episode of syncope may beįrightening, not only for the patient, but for observers as well.
