Study objects and grouping
5220 young female patients (≤ 44 years old) underwent coronary angiography (CAG) due to chest pain or discomfort in Beijing Anzhen Hospital and Affiliated Hospital of Beihua University from January 2003 to January 2022. Of them, 2684 (51.42%) were diagnosed with ACS. After patients with diabetes, high cholesterol, and smoking were excluded, 1772 patients with ACS were selected as study objects. According to whether the patient suffered from essential hypertension (EH), they were divided into EH combined with ACS group (EH-ASC group; n = 824) and non-hypertension ACS group (control group; n = 948) (See Fig. 1). The severity of coronary artery lesions and follow-up results were compared between the two groups.
