Number of Implanted Stents May Predict Posttraumatic Stress Disorder in Patients With Acute Myocardial Infarction

Background: This study is intended to explore the confounding factors associated with posttraumatic stress disorder (PTSD) in Chinese Han population with acute myocardial infarction (MI). Methods: 300 acute MI patients were enrolled in this study, the demographic data, complicating diseases, medication, and perioperative procedures were documented. The PTSD was evaluated using the PTSD checklist-civilian version (PCL-C) scale one month after the occurrence of MI. Results: 97 (32.3%) patients were diagnosed as PTSD after finishing the PCL-C scale. The intra-aortic balloon pump (IABP) implantation and use of diuretic in PTSD patients with acute MI were significantly higher than those in non-PTSD patients with acute MI. The age, body mass index (BMI), heart rate, number of stents, urea nitrogen, white blood cells counts, creatine kinase-MB, myoglobin, troponin I, brain natriuretic peptide (BNP), total cholesterol, triglyceride, high-density lipoprotein-cholesterol, low-density lipoprotein-cholesterol, apolipoprotein A and apolipoprotein B were significantly and positively correlated with PTSD score (all P < 0.05). After the adjustment of the confounding factors, the number of stents was significantly associated with PTSD in acute MI patients ( OR = 4.131, P = 0.003), meanwhile we also documented the troponin I and BNP were also significantly associated with PTSD in acute MI patients ( OR = 1.066, P = 0.046; OR = 1.002, P = 0.019; respectively). The PTSD scores were 39.72 ± 11.12, 44.85 ± 13.46, 47.69 ± 9.39 and 49.33 ± 18.14 in acute MI patients with 1, 2, 3 and 4 stents respectively ( P = 0.008). Conclusion: The study found that the number of implanted stents may predict PTSD in Chinese Han patients with acute MI.
