Atrial septal aneurysm (ASA), common finding in normal echocardiographies, has been described in association with transient ischemic attacks (TIAs)/strokes, as well as hypertensive end-organ damage such as left ventricular (LV) hypertrophy. Aim of this study was to assess if a cluster of echocardiographic aspects could characterize TIA hypertensive patients. A cross-sectional study on patients with history of TIA, referring to a Hypertension Center echolab, has been performed. A total of 5223 patients received transthoracic echocardiography. TIA patients were 292 (5.6%). A total of 102 age/sex-matched patients without TIA have been collected as controls. The main characteristic of TIA patients resulted ASA/bulging (B) (TIA 61%, controls 6%, P = .0001). Other aspect was LV concentric remodeling (TIA 32.3%, controls 20.8%, P = .029) and mitral flow aspects of diastolic dysfunction. After adjustment for age and hypertension, ASA/B (odds ratio [OR] = 62.4, 95% confidence interval [CI]: 13.6-73.9, P < .001), followed by LV concentric hypertrophy (OR = 2.1, 95% CI: 1.1-4.3, P = .043), was associated with a positive TIA history. A binary logistic regression performed in ASA/B patients, identified relative wall thickness as the strongest TIA-associated aspect (OR = 53.4, 95% CI: 11.9-74.18, P = .001). ASA/B, common finds in general population, could carry a significant incremental possibility of association with TIA when concentric geometry, frequent hypertensive aspect, is present as well.
