Atherosclerosis appears to be a disease with a multifactorial pathogenesis. The factors participating in its etiology are called risk factors [Fejfar 1972; Stamler 1983]. These may be divided into a group of uninfluencible risk factors (age, sex, genetic load, etc.) and influencible risk factors of first or second order. Hyperlipidemia may be considered as influencible risk factor of the first order [Goldstein et al. 1973]. From this reason it is necessary to investigate the etiology of lipoprotein metabolic disorders and the possibilities of their treatment and prevention. Hormonal influences are also considered to be one of the influencible risk factors which may affect a number of steps in lipoprotein metabolism.

Many patients with hyperlipidemia are without symptoms, thus laboratory data are often the sole index of therapeutic success or failure. Aggressive laboratory investigation of patient and family may identify inherited hyperlipidemia long before the clinical manifestations of atherosclerosis. The classification system of Fredrickson et al and Goldstein et al are reviewed from an historical and a clinician's point of view. Specific phenotypes and phenocopies, their causes, clinical manifestations, and management are presented. The basic laboratory assessment of hyperlipidemia is described, specialized testing is reviewed, and promising new methodologies are discussed.

The present study aims to evaluate the diagnostic value of four-dimensional CT angiography (4D-CTA) in the diagnosis of arterial erectile dysfunction (ED) using 320-detector row dynamic volume CT. Arterial ED patients attributed to arterial insufficiency were enrolled. To induce penile erection, an intracavernous injection (ICI) of corpus cavernosum with a vasoactive drug was administered. Patients were assigned into the erection hardness score (EHS) 1/2 group or EHS 3/4 group. Color duplex Doppler ultrasound (CDDU) was used to analyze blood flow spectrum. Each patient was examined using 4D-CTA. Receiver operating characteristic (ROC) curve was plotted to evaluate the diagnostic value of 4D-CTA in arterial ED. According to Irwin Goldstein, the EHS 3/4 group (n=38) had a shorter course of ED and low proportion with history of hypertension, hyperlipidemia, and diabetes than the EHS 1/2 group (n=35). The peak systolic velocity (PSV), end diastolic velocity (EDV), and resistant index (RI) in the EHS 3/4 group were lower than those of the EHS 1/2 group. 4D-CTA showed there were a total of 35 cases in the EHS 1/2 group (two cases missed) and 38 cases in the EHS 3/4 group (seven cases misdiagnosed). Using 4D-CTA to diagnose arterial ED, the area under the ROC curve yielded a value of 0.879, with a specificity of 93.9% and a sensitivity of 82.5%. These findings indicated that 4D-CTA using 320-detector row dynamic volume CT is a promising and reliable utility in diagnosing arterial ED.
