The coronary slow flow phenomenon (CSFP) is the slow passage of the angiographic contrast agent to the distal portion of the coronary artery in the absence of significant stenosis. We evaluated the left atrial (LA) function in patients with the CSFP using two-dimensional speckle-tracking echocardiography (2DSTE).
The LA function was compared through 2DSTE between 36 patients with the CSFP and 36 participants with a normal coronary flow. The two groups were matched for age, sex, hypertension, diabetes mellitus, and the left ventricular function.
There were no statistically significant differences between the CSFP group and the control group regarding longitudinal systolic strain, early and late diastolic strains, and the strain rate of the LA myocardium.
The LA function as evaluated with 2DSTE was not different between the CSFP group and the normal coronary flow group when they were matched for age, sex, hypertension, diabetes, and the left ventricular function.
冠状动脉慢血流现象（CSFP）是指在冠状动脉无明显狭窄的情况下，血管造影对比剂向冠状动脉远端缓慢通过。我们使用二维斑点追踪超声心动图（2DSTE）评估了CSFP患者的左心房（LA）功能。
通过2DSTE比较了36例CSFP患者和36例冠状动脉血流正常参与者的LA功能。两组在年龄、性别、高血压、糖尿病和左心室功能方面相匹配。
CSFP组和对照组在LA心肌的纵向收缩应变、舒张早期和晚期应变以及应变率方面无统计学显著差异。
当CSFP组和正常冠状动脉血流组在年龄、性别、高血压、糖尿病和左心室功能方面相匹配时，用2DSTE评估的LA功能没有差异。
