| Popis: | Pretreatment blood pressure reliably predicts progression of chronic nephropathies. Background Random, nontimed blood pressure (BP) measurements in the outpatient clinic may fail to provide reliable information on actual daily BP control in renal patients on chronic antihypertensive therapy. Methods In a cohort of 163 patients with proteinuric chronic nephropathies followed prospectively with repeated BP and glomerular filtration rate (GFR) measurements, we compared baseline and follow-up pretreatment, morning ("trough," measured by standard procedures, and "0 minutes," measured by an automatic device) and post-treatment (120 minutes) measurements, with BP monitored up to 600 minutes after treatment administration. We then evaluated which BP value most reliably predicted GFR decline (δGFR) and progression to end-stage renal failure (ESRF) over a median (interquartile range) follow-up of 20 (9 to 25) months. Results GFR decline was more reliably predicted by systolic as compared with diastolic BP and by pretreatment as compared to post-treatment BP, regardless of the timing and method of measurement, respectively. In particular, at the 120-minute baseline and follow-up measurements, systolic BP had no predictive value in patients with less severe renal insufficiency and baseline diastolic BP, regardless of the level of renal dysfunction. The BP predictive value was remarkably higher in ramipril than in conventionally treated patients. All follow-up—but no baseline—measurements reliably predicted the risk of ESRF in the entire study group. Conclusions In patients with progressive chronic nephropathies, systolic BP and pretreatment morning BP measurements are the most reliable predictors of disease outcome and may serve to guide antihypertensive therapy in routine clinical activities and in prospective controlled trials, particularly in patients on angiotensin-converting enzyme inhibitor therapy. Reliability and relevance of single measurements taken at different times after treatment administration are questionable. |
