摘要
To explore the mechanisms of obesity-induced hypertension we analyzed the sequential changes in cardiovascular and renal function in adult rabbits switched to high-fat diet (HFD) for 8 weeks. Animals were housed in metabolic cages for continuous 24-h recording of arterial pressure by telemetry and daily urine collection. High-fat diet induced a progressive increase in body weight (+47%) and a rapid rise in mean arterial pressure, heart rate, and glomerular filtration rate that stabilized, respectively, at 1.4%, 31% and 68% greater than control values. Time-course analysis of changes in blood pressure may reveal two components of obesity-induced hypertension, an early phase related to HFD itself and a later phase related to weight gain.
