Abstract

Objective: Prediabetes mellitus, hypertension, and their frequent coexistence are risk factors for macrovascular and cardiovascular complications. In this study we aimed to determine the relationship between spexin levels and echocardiographic findings and hypertension in prediabetic patients. Methods: This study included 118 adult patients diagnosed with prediabetes mellitus who presented to outpatient clinics between April 2021 and January 2022. The patients were grouped into prediabetic patients with hypertension (n = 58) and those without hypertension (n = 60). The hypertension group was further divided into dipper and non-dipper groups according to the 24-hour ambulatory blood pressure monitoring. Blood samples were collected from all patients and echocardiography was performed. Spexin levels were measured by ELISA. Serum spexin levels, echocardiographic and ambulatory blood pressure monitoring findings were compared between the groups. Results: The hypertension and non-dipper groups had significantly lower spexin levels and higher left atrial volume index, E/Em index, and interventricular septum and posterior wall thicknesses. Spexin levels were negatively correlated with body mass index (r = -0.298, P < 0.001), nighttime systolic blood pressure (r = -0.264, P = 0.006), nighttime diastolic blood pressure (r =-.255, P = 0.005), left atrial volume index (r =-.238, P = 0.009), E/Em (r =-.214, P = 0.020), and low-density lipoprotein cholesterol (r = -.243, P = 0.008). Obesity, overweight and spexin <780 pg/mL were independently associated with hypertension. Conclusion: Circulating spexin levels were lower in prediabetic patients with overall hypertension and in non-dipper patients, and were associated with echocardiographic and lipid parameters. The cut-off value of spexin identified in our study may be a useful indicator for hypertension detection and raise clinicians’ awareness about evaluating prediabetic patients for hypertension.
