Key result
Insufficient diagonal branch flow after primary angioplasty for acute anterior STEMI was associated with significantly lower left ventricular ejection fraction (32.92% vs. 39.0%, P=0.018) and higher wall-motion score index.

Does insufficient diagonal branch flow after primary angioplasty worsen left ventricular systolic function in patients with first anterior STEMI?
In patients with first anterior STEMI undergoing primary angioplasty, insufficient diagonal branch flow is associated with worse left ventricular systolic function.

May identify higher-risk anterior STEMI patients for closer monitoring; hypothesis-generating and requires prospective validation before practice change.
Background: There are few studies about the impact of diagonal branch blood flow on echocardiographic findings in patients with first acute anterior myocardial infarction undergoing primary angioplasty. Objectives: We aimed to compare left ventricular systolic function measures in patients with first acute anterior ST-segment elevation myocardial infarction (STEMI) treated with primary angioplasty based on diagonal branch blood flow after the procedure. Methods: This study was a single-center study that enrolled patients with their first acute anterior STEMI treated with primary angioplasty in our center between October 2020 and March 2021. Patients were divided into two groups: The patients with final thrombolysis in myocardial infarction (TIMI) flow III in diagonal (sufficient diagonal flow) and patients with final TIMI flow less than III in diagonal (insufficient diagonal flow) after the procedure. The left ventricular Wall-Motion Score Index (WMSI) and left ventricular ejection fraction (LVEF) were compared between the two groups. Results: A total of 107 patients with first anterior STEMI treated with primary PCI were enrolled in the present study, of which 13 patients (12.1%) had insufficient diagonal flow after primary coronary angioplasty. The LVEF was lower in patients with insufficient diagonal flow (32.92 ± 7.29% vs. 39 ± 8.68%, P = 0.018). Also, this group had higher LV WMSI (1.68 ± 0.28 vs. 1.49 ± 0.26, P = 0.029). Conclusions: The present study showed that in patients with first acute anterior STEMI undergoing primary angioplasty, insufficient diagonal branch flow after the procedure was associated with worse left ventricular systolic function and higher LV WMSI.

Raadi et al. (2023) conducted an observational in First acute anterior ST-segment elevation myocardial infarction (STEMI) (n=107). Insufficient diagonal branch flow (TIMI < 3) vs. Sufficient diagonal branch flow (TIMI 3) was evaluated on Left ventricular ejection fraction (LVEF) (p=0.018). Insufficient diagonal branch flow after primary angioplasty for acute anterior STEMI was associated with significantly lower left ventricular ejection fraction (32.92% vs. 39.0%, P=0.018) and higher wall-motion score index.
