OBJECTIVE: Exaggerated exercise blood pressure (BP) predicts mortality. Some studies suggest this could be explained by chronic hyperlipidemia, but whether acute-hyperlipidemia effects exercise BP has never been tested, and was the aim of this study. METHODS: Intravenous infusion of saline (control) and Intralipid were administered over 60 min in 15 healthy men by double-blind, randomized, cross-over design. Brachial and central BP (including, pulse pressure, augmentation pressure and augmentation index), cardiac output and systemic vascular resistance were recorded at rest and during exercise. RESULTS: Compared with control, Intralipid caused significant increases in serum triglycerides, very low density lipoproteins and free fatty acids (p < 0.001 for all). However, there was no significant difference for any exercise hemodynamic variable (p > 0.05 for all). CONCLUSION: Acute-hyperlipidemia does not significantly change exercise hemodynamics in healthy males. Therefore, the association between raised lipids and increased exercise BP is likely due to the chronic effects of hyperlipidemia.
