At present, literally no one disputes hyperlipoproteinaemia and dyslipidemia (HLP and DLP) treatment as a rational therapeutic approach in the prevention of cardiovascular diseases (CVD). This approach is in line with the current principles of evidence-based medicine (EBM) and is sufficiently evidenced particularly by the results of large intervention studies. Nevertheless! When the results of the recent studies are critically appraised, these by no means are (mostly, there, obviously, are exceptions) as conclusive as the studies conducted in 1980s and 1990s. Consequently, positive results are being sought in subanalyses, subgroup evaluations and multiple-study metaanalyses. This paper is not intended as a critique of new drugs. These certainly are developed to be safe, effective and well-tolerated. However, the newer studies suffer from a range of issues: the populations studied are already very well managed, it is not possible to compare against placebo and sometimes, let us be honest, the trial design itself is problematic (often it is an uncritical effort to treat as wide as possible range of patients as well as new groups of patients who might not be suitable for the given treatment). Certainly, we should not start disputing the well-evidenced hypotheses and seek alternatives to the long-established arguments and approaches as a consequence to some less convincing studies. We must not overlook the most robust results of statin studies as well as 'positive' studies with other hypolipidemics. There is no doubt that the effect ofstatins on LDL-cholesterol represents a significant move towards cardiovascular disease prevention. Despite this, we currently recognise with increased intensity that this very effective and well-evidenced treatment has its limits and that a high proportion of patients dies or are faced with cardiovascular diseases even though they are treated with a correct dose ofa statin and a target LDL-C level is achieved. This remaining risk (represents more than 50% ofevents) has been termed 'RESIDUAL RISK'. The issue of residual risk is crucial in patients with type 2 diabetes mellitus (DM2T) or in all patients with HDL-C-low DLP. As was repeatedly emphasised, a statin will be a cornerstone of pharmacological treatment of a DLP. However, a question arises what to combine it with. The most convincing data exist for niacin (combination of niacin with laropiprant minimising the incidence of unwanted flushes). We surely should not marginalize other hypolipidemics used mainly in combinations: resin and ezetimibe to treat LDL-C, niacin, fibrates and possibly omega-3-fatty acids to manage the residual risk (HDL and TG). Last but not least we should not forget non-pharmacological treatment as the pivotal treatment approach in all patients.

Cardiovascular diseases remain the most important cause of death worldwide. The situation in the Czech Republic is one of the best when compared to the other countries of the former socialist block; on the other hand, we significantly lack behind when the comparison is made to south and southwest European countries. The concept of risk factors (RF) and multifactorial character of atherosclerosis as the main cause of cardiovascular diseases (CVD) is fully accepted at present. Hyperlipoproteinaemia (HLP) and dyslipidemia (DLP) are a group of high incidence metabolic diseases characterised by increased levels of lipids and lipoproteins in plasma or, in case of DLP, by unsuitable, atherogenic composition of lipids and lipoproteins in plasma. HLP and DLP are among the most important RF for the development of CVD. Mainly LDL-cholesterol (LDL-C) is perceived as a very important risk factor; successful reduction of LDL-C is linked to a reduction in cardiovascular risk. Even when LDL-C is decreased and the so-called "target values" achieved, patients are still at risk ofa CV event. This remnant risk is the so called "residual risk". The most important "rival" to LDL-cholesterol among the risk factors is the metabolic syndrome, or rather the DLP associated with the metabolic syndrome, characterised from the perspective of DLP by low levels of HDL-cholesterol and increased triglycerides with concurrent occurrence of "small dense LDL". The issue of heterogeneity and atherogenicity oflipoprotein particles in general then becomes topical. Lipoprotein (a)--Lp(a) is another important lipid risk factor that is getting a significant attention.
