LEFT ATRIAL STRAIN MEASURED BY SPECKLE TRACKING ECHOCARDIOGRAPHY IN PATIENTS WITH ARTERIAL HYPERTENSION
Main Article Content
Abstract
Objectives: To investigate left atrial strain by speckle tracking echocardiography in hypertensive patients, the relationship between left atrial strain and left ventricular diastolic dysfunction. Subjects and methods: The study was conducted on 142 hypertensive patients, from November 2022 to March 2023 at Military Hospital 103. Echocardiography was performed to evaluate left atrial and left ventricular function. Results: Mean age 70.3 ± 12.3 years, 70.4% were men, of which 54,2% hypertensive patients had left ventricular diastolic dysfunction. The left atrial strain assessment parameters (LASr-ED, LAScd-ED, LASct-ED, LASr-AC, LAScd-AC, LASct-AC) in hypertensive patients were 24.2 ± 14.4%, -11.8 ± 7.7%; -12.5 ± 10.7%; 20.8 ± 10.7%; -10.5 ± 6.9%, -10.3 ± 8.3%, respectively. Left atrial strain reservoir (LASr) in patients with hypertension > 10 years (16.9 ± 10.4%) was significantly lower than in patients with hypertension < 5 years (28.1 ± 15.5%) and patients with hypertension 5 - 10 years (28.6 ± 14.3%) (p < 0,05). LASr was more reduced in hypertensive patients with left ventricular diastolic dysfunction compared to the group with normal left ventricular diastolic function ((21.6 ± 13.4% vs 27.3 ± 14.8%, p = 0.02). LASr was inversely correlated with E/E' septum (r = -0.21, p < 0.001), E/E' lateral (r = -0.31, p < 0.001), LAVmax (r = - 0.45, p = 0.001), LAVmin (r= -0.64, p = 0.013), positively correlated with LAEF (r = 0.71, p = 0.005). Conclusions: Left atrial strain decreased significantly in patients with hypertension > 10 years compared to the patients with hypertension < 5 years. Left atrial strain decreased in hypertensive patients with left ventricular diastolic dysfunction compared to the group with normal left ventricular diastolic function.
