Increased Fibrinolytic Potential after Diet Intervention in Healthy Coronary High‐risk Individuals

Twenty healthy individuals (15 men and 5 women) with initial fasting serum triglycerides greater than or equal to 1.80 mmol/l and euglobulin clot lysis time after venous occlusion greater than or equal to 60 min (upper normal limit 45 min) were tested for fibrinolytic response to venous occlusion and intravenous injection of desmopressin (DDAVP), serum lipids, serum glucose and relative body weight before and after a minimum of 3 to a maximum of 12 months' diet intervention. In order to be defined as a good diet responder, at least 20% reduction of the initial serum triglyceride concentration was required. At the end of the study, half of the participants (7 men and 3 women) met the criteria of good diet responders. All of these showed an improved fibrinolytic response to DDAVP injection, and 7 out of 10 had a normalized fibrinolytic response to venous occlusion. We conclude that, through dietary measures with substantial reduction of hypertriglyceridaemia, it is possible to improve and even normalize the fibrinolytic potential.
