FFA-Induced Hypertension and Endothelial Dysfunction

In this arm subjects received Intralipid 20% Intravenous IV continuous infusion at 20cc/hour for 8 hours. The 20% intralipid solution is a long-chain triglyceride emulsion composed of 50% polyunsaturated fatty acids, 26% monounsaturated fatty acids, and 19% saturated fatty acids. During the intralipid infusion studies, subjects remained fasting

In this arm subjects received 0.9% Normal Saline continuous IV infusion at 40/cc for 8 hours.

In this arm subjects received oral liquid fat load prepared by the General Clinical Research Center (GCRC) at baseline and every 2 hours for 6 hours. Participants received fat with Free Fatty Acids (FFA) composed of 33% polyunsaturated fatty acids, 34% monounsaturated fatty acids, and 22% saturated fatty acids. The oral fat load in either low or high dose was given in four equally divided doses at 0, 2, 4, and 6 h.

In this arm subjects received 60-gram oral fat load intake at baseline and every 2 hours for 6 hours prepared by the General Clinical Research Center (GCRC).
