title: Measuring serum total cholesterol: do vascular surgeons know what they are doing?
abstract: Raised serum total cholesterol (TC) is an accepted risk factor for both coronary and peripheral vascular disease and three landmark trials have shown the benefit of lowering TC using statins. Vascular surgeons tend to measure TC, but little is known about how they manage hypercholesterolaemia or whether they believe treatment will be of benefit. A questionnaire was sent to listed members of the Vascular Surgical Society of Great Britain and Ireland seeking responses to a range of questions on the measurement and management of raised TC. In all, 374 questionnaires were sent out. The response rate was 67%. Over 90% of respondents said they measured TC and considered a level below 5.5 mmol/l as normal. The cut-off for initiating drug therapy, referral to a dietician or to a lipid specialist varied from 5.5 to 7.5 mmol/l. Most (62%) believed that lowering TC improved coronary mortality, but fewer (26%) that it prevented worsening of claudication. Although most vascular surgeons check for raised TC, the level at which treatment begins and the form it takes varies; in many cases being at odds with recommendations. Few surgeons are convinced of the benefits of lowering TC for claudication and nearly one-fifth do not believe it improves coronary mortality.
