  • Does albuminuria predict cardiovascular outcome on treatment with losartan versus atenolol in hypertension with left ventricular hypertrophy? A LIFE substudy
  • 2004

  • Tidskriftsartikel (refereegranskat)abstract
    • OBJECTIVES: To examine a possible relationship between baseline albuminuria and effect of losartan versus atenolol on cardiovascular (CV) events in hypertensive patients with left ventricular hypertrophy, the effect of losartan versus atenolol on albuminuria, and whether the benefits of losartan versus atenolol could be explained by influence of losartan on albuminuria. DESIGN: Double-blind, randomized, controlled trial of 4.8 years. SETTING: Out-patient setting. PATIENTS: A total of 8206 with hypertension and left ventricular hypertrophy. INTERVENTIONS: Losartan or atenolol, supplemented with diuretics and/or calcium antagonists to reach blood pressure < 140/90 mmHg MAIN OUTCOME MEASURES: The urine albumin/creatinine ratio, and the primary composite endpoint (CEP) of CV death, myocardial infarction, and stroke. RESULTS: The blood pressure was reduced similarly on losartan (30.2/16.6 mmHg) versus atenolol (29.1/16.8 mmHg). The risk of a primary CEP increased linearly from the lowest to the highest decile of baseline albuminuria. The benefits of losartan versus atenolol for the primary CEP and for stroke tended to be more pronounced among patients above the median value for baseline albuminuria (urine albumin/creatinine ratio, 1.28 mg/mmol). The decrease in albuminuria was significantly greater with losartan versus atenolol throughout the study (a decrease from baseline to year 2 of 33% losartan versus 25% atenolol). One-fifth of the difference in favor of losartan on the primary CEP was explained by the greater reduction in albuminuria on losartan. CONCLUSIONS: Baseline albuminuria is a powerful risk factor for CV events. Baseline albuminuria did not identify the group of patients with greatest benefit on losartan versus atenolol in LIFE. Reduction in albuminuria explained one-fifth of the benefits of losartan versus atenolol.

  • Albuminuria predicts cardiovascular events independently of left ventricular mass in hypertension: a LIFE substudy
  • 2004
  • Ingår i: J Hum Hypertens. - 0950-9240. ; 18:6, s. 453-9
  • Tidskriftsartikel (refereegranskat)abstract
    • 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.

  • Effect of losartan versus atenolol on aortic valve sclerosis (a LIFE substudy)
  • 2004
  • Ingår i: Am J Cardiol. - 0002-9149. ; 94:8, s. 1076-80
  • Tidskriftsartikel (refereegranskat)abstract
    • Neither losartan- nor atenolol-based antihypertensive regimens could prevent the progression of aortic valve (AV) sclerosis in elderly, high-risk hypertensive patients, and the regression of AV sclerosis did not translate into reduced cardiovascular risk.
