Abstract

A descriptive observational study of a case series, with comparison with a control group, was performed at Bach Mai hospital on 97 patients with heart failure with left ventricular ejection fraction ≥40% (with and without the syndrome)and 32 in the control group. Results: The ultrasound parameters of left ventricle, right ventricle, systolic function, diastolic function of patients with and without HCCH were similar. In patients with heart failure with an ejection fraction ≥ 40% with atrial fibrillation, the left atrial volume index tends to be greater than in patients without atrial fibrillation. The fractions of left atrial emptying in the group with HCCH were lower than in the group without HCCH. The function of blood flow, ejection, and blood storage of the left atrium tended to be lower in the group with more severe NYHA class. As the left ventricle is dilated and thickened, the left atrial diameter index and the left atrial volume index tend to increase. There is a negative linear correlation between left atrial blood storage function and body mass index (BMI) according to the equation: Y = -0.91. BMI + 78.91.
