OBJECTIVE
To study elderly hypertensive patients with trace albuminuria (urine albumin to creatinine ratio (UACR)) and the relationship between the occurrence of new cardiovascular events, to provide a basis for early prevention in elderly patients with high blood pressure.
METHODS
A total of 3564 elderly patients with high blood pressure were enrolled in the study. Based on UACR, patients were divided into four groups (group A: 0.05-3.20 mg/g; group B:3.21-10.04 mg/g; group C: 10.05-19.33 and group D: 19.34-30.00 mg/g). All patients underwent follow-up for an average period of 3.8 years. Four groups were compared for new cardiovascular events and they were correlated with UACR.
RESULTS
Through multivariate Cox proportional hazards regression analysis, the relative risk of cardiocerebrovascular events, cerebral infarction, and acute myocardial infarction (mi), in group D was 1.74 times (p < 0.05), 1.66 times (p < 0.05), and 2.48 times (p < 0.05), respectively. UACR level in females and those with higher age, body mass index, systolic blood pressure, fasting blood glucose, TG, TC, LDL-C levels and lower HDL-C were higher. During follow-up, patients from group D with sudden cardiac death, acute myocardial infarction, cerebral hemorrhage, cerebral infarction occurrence was significantly higher than group A (χ2 = 79.3, p = 79.3) CONCLUSIONS: According to UACR level, we can perform early prevention for elderly patients with high blood pressure, thus reducing the occurrence of cerebral infarction and myocardial infarction.
