Impact of lipid disorders on mortality among Saudi patients with heart failure

Background: dyslipidemia,a known cardiovascular risk factor,is extremely common among saudis,both adults and children. the impact,however,of dyslipidemia and several other lipid disorders in patients with congestive heart failure in this particular population has not been documented. this study aims to fill the gap. methods: this retrospective,single center study was conducted at king abdulaziz medical city,riyadh,saudi arabia. of the 500 cases seen during the period between 2002 and 2008,392 were included in the study. charts were reviewed and information on medical history,medications,and lipid status were documented. results: low hdl-cholesterol level was the most common lipid disorder with 82.9%,followed by hypertriglyceridemia (35.2%),atherogenic dyslipidemia (27.8%),and hypercholesterolemia (9.2%). diabetes mellitus was the single most significant predictor of mortality (. p=. 0.001). among the lipid disorders,only low levels of hdl-cholesterol contributed to significant mortality risk [or 1.29 (confidence interval 1.04-1.59) (. p-value. <. 0.01)] adjusted for age,gender and statin use. conclusion: the results of this study suggest that emphasis should be on the elevation of hdl-cholesterol levels among subjects with congestive heart failure,without compromising any ongoing management of ldl-lowering drugs. management should not be limited to conventional statin use and should promote other treatments to elevate hdl-cholesterol levels. © 2015 .
