OBJECTIVE: Many studies have shown that patients with coronary artery disease have an exaggerated rise and a delayed fall of plasma triglyceride (TG) concentration postprandially. We examined whether patients with essential hypertension have the same response to a fatty meal. METHODS: A fatty meal (350g per 2 m(2) body surface with 83.5% fat) was given to 25 patients with essential hypertension (H) and to 25 normotensives (N). The two groups were matched for age, body mass index, lipid profile, basal glucose and insulin concentrations, and an index of homeostasis model of insulin resistance (HOMA-IR). A quantitative insulin sensitivity check index (QUICKI) was calculated. Blood samples were taken at 0, 4, 6, and 8 hours after the fatty meal. Lipid variables were measured in all samples. Blood glucose and insulin levels were measured in the fasting state. RESULTS: Total and high density lipoprotein cholesterol, apolipoprotein A1 and B, lipoprotein (a), HOMA-IR and QUICKI did not differ significantly over time between the groups. The plasma TG concentration (mg/dL) increased significantly after fat loading in H (from 118 +/- 31 to 284 +/- 137 at 4 hours, 327 +/- 93 at 6 hours and 285 +/- 71 at 8 hours) compared to N group (from 105 +/- 29 to 150 +/- 38 at 4 hours, 148 +/- 40 at 6 hours and 115 +/- 34 at 8 hours), p = 0.001, p < 0.001 and p < 0.001, respectively. CONCLUSION: This study suggests that patients with hypertension have an exaggerated response and delayed clearance of plasma TG concentration after fat loading.
