Assessment and Management of Atrial Fibrillation in Older Adults with Frailty.

Atrial fibrillation (AF) is a major driver of morbidity and mortality among older adults with frailty. Moreover, frailty is highly prevalent in older adults with AF. Understanding and addressing the needs of frail older adults with AF is imperative to guide clinicians caring for older adults. In this review, we summarize current evidence to support the assessment and management of older adults with AF and frailty, incorporating numerous recent landmark trials and studies in the context of the 2023 US AF guideline.

The utility of the bilateral temporal artery biopsy for diagnosis of giant cell arteritis.

OBJECTIVE: A surgical temporal artery biopsy (TAB) is the gold standard for diagnosis of giant cell arteritis (GCA). The necessity of performing a bilateral biopsy remains under debate. The primary objective of this study was to assess the rate of discordance between pathology results in patients who underwent bilateral TAB for suspected GCA. METHODS: We performed a retrospective review of patients who underwent bilateral TAB for the diagnosis of GCA between 2011 and 2020. The primary end point was the rate of discordance between specimens for patients with pathology positive GCA. Secondary end points included assessments of the sensitivity of preoperative temporal artery duplex and the effects of specimen length and specialty of referring provider on the diagnostic yield of the biopsy. RESULTS: During the study period, 310 patients underwent bilateral TAB for the diagnosis of GCA. These patients were primarily female (73.9%), elderly (mean age, 70.8 years), and Caucasian (95.8%). Preoperative symptoms for patients were typically bilateral (59%) and included headache (81%), vision changes (45.2%), and temporal tenderness (32.6%). Most patients (85.2%) were on preoperative steroid therapy at the time of surgical biopsy with a mean preoperative duration of steroid therapy of 15.1 days. Overall, 91 patients (29.4%) had a positive pathologic diagnosis after bilateral TAB. Of these patients, 11 had a positive pathology result in only a single specimen, resulting in a discordance rate of 12.1%. Preoperative temporal artery duplex demonstrated a low sensitivity (27.3%) for identifying patients with pathologic positive disease. There were no significant differences between the pathology-positive and -negative patients in terms of mean surgical specimen length (1.67 cm vs 1.64 cm; P = .67) or the specialty of the referring provider (P = .73). CONCLUSIONS: At our institution, we observed a 12.1% discordance rate between pathology results in patients who underwent bilateral TAB for diagnosis of GCA. A preoperative temporal artery duplex provided little value in identifying patients with biopsy-proven GCA.
