Tìm hiểu mối liên quan giữa một số yếu tố lâm sàng và siêu âm tim nhĩ trái ở bệnh nhân bệnh thận mạn

To investigate the correlation between clinical factors and left atrial echocardiography in patients with chronic kidney disease. Subject and method: The study was conducted on 150 subjects with chronic kidney failure who were treated at Bach Mai Hospital from April to October 2022. All patients were examined. Transthoracic echocardiography was performed to assess left atrial size and strain. Result: Glomerular filtration rate (MLCT), hemoglobin was inversely correlated with left atrial diameter (LAD) (r = -0.51, p<0.001, r = -0.27, p=0.002.). Age at cardiovascular risk (men > 60 years old, women > 55 years old) had a 2.9 times higher risk of decreased blood reservoir in the 4-chamber view compared with patients of same age without cardiovascular risk (OR = 2.9), 95% CI: 1.4-4.5). Elevated systolic blood pressure was 7.85 times more likely to have left atrial dilation than patients without systolic hypertension (OR = 7.85, 95% CI: 3.89-16.79, p<0.05). Increased diastolic blood pressure was 2.58 times more likely to have left atrial dilation than patients without diastolic hypertension (OR = 2.58, 95% CI: 1.67-6.20, p<0.05). Diabetes had a 3.59 times higher risk of decreased blood reservoir function in the 4- chamber view compared with elderly patients without cardiovascular risk (OR = 3.59, 95% CI: 1.8-6.2). Conclusion: Age at CV risk (men > 60, women > 55), diabetes, and hypertension are clinical factors correlated to size and left atrial strain in patients with chronic kidney disease.
