Introduction and importance: Chest pain is a frequent reason patients seek medical attention. The broad spectrum of potential etiologies makes determining the underlying cause of chest pain complex. Among cardiovascular etiologies, aortitis is a rare but life-threatening possibility that should be considered in the differential diagnosis. Case presentation: A 53-year-old female with a history of smoking presented with progressively worsening chest and epigastric pain over several weeks. She had seen multiple physicians previously for the same symptoms with unremarkable work-ups. Physical examination was notable for severe tenderness upon palpation of her lower abdomen. The electrocardiogram and troponins were unremarkable. Computed tomography of the abdomen revealed aneurysmal dilatation of the abdominal aorta, soft tissue thickening, and surrounding inflammatory stranding, consistent with aortitis. Infectious and autoimmune work-ups were unremarkable. Intravenous steroids were initiated, and her symptoms improved significantly. Her aortitis was attributed to inflammation secondary to chronic smoking. Clinical discussion: Aortitis is a rare condition with varied clinical presentations. Etiologies of aortitis include infection and non-infectious inflammation. Diagnosis of aortitis requires a thorough clinical assessment and prompt imaging of the aorta, with computed tomography being the preferred imaging modality. Conclusion: Evaluation for cardiovascular chest pain must extend beyond an electrocardiogram and troponin level. Imaging should be considered in patients with atypical symptoms. Aortitis is a rare but important diagnosis requiring immediate treatment.

Introduction: Intracranial hemorrhage (ICH) is associated with high mortality rate of 30-52% despite current advances in management. New cardiovascular abnormalities (CA), such as EKG or cardiac biomarker abnormalities ensue in ICH and are postulated to be due to hypothalamic injury and catecholamine surge. These CA are thought to portend a poor prognosis. Methods: We evaluated clinical studies reporting CA in ICH and assessing their effect on mortality. Studies without a control group, pediatric, and non-English literature were excluded. We extracted data on demographics, comorbidities and mortality [in-hospital (IHM), 30 day (30M) and 90 day (90M)]. CA data included EKG changes (bradycardia, atrial fibrillation, bundle branch blocks, QTc prolongation, ST-segment depression, and ST-segment elevation), biomarker elevation (troponin-T (TnT), CK-MB and BNP), and wall motion abnormalities (WMA). Unadjusted and adjusted rates for CA and pooled risk ratio (RR) with 95% CI were calculated using Mantel-Haenszel random effects model for mortality. Results: We reviewed 453 studies, of which 26 met our inclusion criteria. Heterogeneity varied from moderate to severe depending on the outcome chosen. Of a total 5580 patients, 2796 (50.1%) had sub-arachnoid hemorrhage (SAH), 1633 ICH (29.3%) and 1151 (20.6%) both. The incidence of CA is presented in Table 1. Of these 26 studies, 19 evaluated the influence of new CA on mortality. IHM was noted in 175/566 (30.9%) and 491/2496 (19.7%) patients with and without CA, respectively. In addition, 30M and 90M were noted in 18/38 (47.4%) vs. 14/136 (10.3%) and 90/175 (51.4%) vs. 247/1139 (21.7%) patients with and without CA, respectively. CA was associated with worse IHM (RR 2.03, 95% CI 1.58-2.62, p<0.001), 30M (RR 3.18, 95% CI 1.86-5.42, p<0.001) and 90M (RR 2.11, 95% CI 1.44-3.08, p<0.001) in patients with ICH compared to those who did not have CA. Conclusion: CA are common in patients with ICH and are associated with worse IHM, 30M and 90M.
