We wanted to investigate whether urine albumin/creatinine ratio (UACR) and left ventricular (LV) mass, both being associated with diabetes and increased blood pressure, predicted cardiovascular events in patients with hypertension independently. After 2 weeks of placebo treatment, clinical, laboratory and echocardiographic variables were assessed in 960 hypertensive patients from the LIFE Echo substudy with electrocardiographic LV hypertrophy. Morning urine albumin and creatinine were measured to calculate UACR. The patients were followed for 60±4 months and the composite end point (CEP) of cardiovascular (CV) death, nonfatal stroke or nonfatal myocardial infarction was recorded. The incidence of CEP increased with increasing LV mass (below the lower quartile of 194?g to above the upper quartile of 263?g) in patients with UACR below (6.7, 5.0, 9.1%) and above the median value of 1.406?mg/mmol (9.7, 17.0, 19.0%***). Also the incidence of CV death increased with LV mass in patients with UACR below (0, 1.4, 1.3%) and above 1.406?mg/mmol (2.2, 6.4, 8.0%**). The incidence of CEP was predicted by logUACR (hazard ratio (HR)=1.44** for every 10-fold increase in UACR) after adjustment for Framingham risk score (HR=1.05***), history of peripheral vascular disease (HR=2.3*) and cerebrovascular disease (HR=2.1*). LV mass did not enter the model. LogUACR predicted CV death (HR=2.4**) independently of LV mass (HR=1.01* per gram) after adjustment for Framingham risk score (HR=1.05*), history of diabetes mellitus (HR=2.4*) and cerebrovascular disease (HR=3.2*). *P<0.05, **P<0.01, ***P<0.001. In conclusion, UACR predicted CEP and CV death independently of LV mass. CV death was predicted by UACR and LV mass in an additive manner after adjustment for Framingham risk score and history of CV disease.Journal of Human Hypertension (2004) 18, 453-459. doi:10.1038/sj.jhh.1001711 Published online 15 April 2004 [ABSTRACT FROM AUTHOR]
