OBJECTIVETo investigate glucose metabolism status and its relationship with blood pressure, obesity, renal function and cardio-cerebral vascular events in Chinese essential hypertensive patients.

METHODSEssential hypertensive patients without diabetic history were enrolled in this cross-sectional survey. All patients filled in questionnaires and received physical examination and laboratory tests. Oral glucose tolerance test (OGTT, fasting and 2 hours glucose level after drinking the 75 g glucose solution) was performed in patients who signed the informed consent.

RESULTS(1) The control rate of systolic BP was lower in patients with dysglycemia than in patients without dysglycemia (41.0% vs. 46.4%, P = 0.000). (2) The albuminuria detection rate and the abnormal rate of estimated glumerular filtration rate (eGFR) increased significantly with the deterioration of glucose metabolism. (3) Multifactor-analysis showed that abnormal waist circumference, decreased eGFR and presence of albuminuria were independent risk factors for abnormal glucose metabolism. Cardiovascular events was significantly higher in patients with abnormal glucose metabolism than patients with normal glucose metabolism.

CONCLUSIONAbnormal glucose metabolism is common in Chinese essential hypertensive patients. When complicated with abnormal glucose metabolism, essential hypertensive patients had poor blood pressure control rate and were related to higher cardiovascular risk.
