RESUMO

PURPOSE: To introduce a rare case of patient with hyperlipidemic myeloma and ocular manifestation in form of masquerade syndrome with acute elevation of intraocular pressure (IOP) and hyperviscous retinopathy. RESULTS: 55-year-old man with newly diagnosed hyperlipidemic myeloma and hyperviscous syndrome was acutely referred to our glaucoma outpatient clinic due to problems with his left eye: sudden pain, blurred vision, redness of the eye and IOP of 44 mm Hg. We excluded attack of angle closure glaucoma and found presence of whitish material in the anterior chamber and blood obstructing the iridocorneal angle. Glaucoma therapy was initiated and lavage of the anterior chamber of the left eye with sampling of the aqueous humour for biochemical and cytological examination was performed. Identification of trace amount of cryoprotein in the samples of humour proved diagnosis of masquerade syndrome. Finding of the hyperviscous retinopathy and nonperfusion of wide peripheral areas of retina in both eyes was indicated to laser coagulation of these areas. The patient underwent in the meantime three times plasmapheresis, four cycles of biological therapy and autologous stem cell transplantation reaching complete remission of the myeloma. Local and systemic therapy led to significant clinical finding improvement on the anterior segment and fundus of both eyes. CONCLUSIONS: Masquerade syndrome can be complicated by acute elevation of IOP. Diagnostic lavage of the anterior chamber, local therapy, systemic therapy and close interdisciplinary cooperation contributed to right diagnosis, IOP normalisation, ocular and general condition improvement.

RESUMO

PURPOSE OF REVIEW: In our pilot study, we aimed to determine how many patients with the statin intolerance history referred to the specialized center for the diagnostics and treatment of lipoprotein metabolism disorders really suffer from a complete statin intolerance. The purpose of the study was to prove that complete statin intolerance is overestimated and overdiagnosed, and with the detailed knowledge of the issue and patient approach, it is possible to find an appropriate statin treatment for the most of patients. RECENT FINDINGS: With the increasing number of statin users worldwide, the issue of statin intolerance has been a frequently discussed topic in recent years. There are many factors that play a role in the manifestation of statin intolerance (predisposing factors as age, sex, and some diseases), genetic factors leading to a different metabolism, drug-drug interactions, psychological reasons, and the negative influence of the mass media. However, it is estimated that true complete statin intolerance, defined by an intolerance of at least three statins at their usual lowest daily doses, occurs in approximately 3-6% of all statin users. In our pilot study, we conducted a retrospective analysis of 300 patients who were referred to the Center of Preventive Cardiology with a history of statin intolerance. During the follow-up treatment, 222 patients (74%) were able to use some statin (rosu-, atorva-, simva-, fluvastatin), and in 21% of the cases (63 patient), the target values according their CV risk level were even achieved. Only 78 patients (26%) were confirmed as being complete statin intolerant following a thorough therapeutic effort. The most tolerated statin was rosuvastatin.

RESUMO

Familial hypercholesterolaemia (FH) is the most common autosomal dominant inheritable disease caused by a defective catabolism of LDL particles. Their subsequent accumulation in circulation accelerates atherosclerotic vascular disease. Untreated FH increases the risk of premature manifestation of atherosclerosis (myocardial infarction - MI- or stroke); it is known that homozygous patients, if not adequately treated, are usually affected by atherothrombotic complications of the underlying disease before 20 years of age and often do not live longer than 30 years. Patients with FH are asymptomatic for a long period of time; their elevated blood lipid levels are often a random laboratory finding. The cardiovascular complications (MI or stroke) may be the primary manifestation of this disease. Clinical signs (xanthomas, xanthelasma or arcus corneae lipoides) occur rarely in these patients but are pathognomic, so at least basal awareness of these findings is necessary. Upon detection of such findings, a diagnostic procedure of FH including blood lipid measuring, careful personal and family history of cardiovascular disease (CVD) and subsequent referral to GPs or to MEDPED specialist is crucial. MEDPED (Make Early Diagnosis to Prevent Early Deaths in MEDical PEDigrees) project associates physicians specializing in patients with severe lipid metabolism disorders including FH. Treatment is based on statins, often in combination with ezetimibe. A great benefit in the treatment of these patients was the discovery of PCSK9 inhibitors, which are very effective and represent a therapeutic option especially for patients with very severe dyslipidaemia or with intolerance of statin therapy. The FH awareness of a plastic surgeon as a first-contact physician, who may be confronted with typical skin or eye manifestations of FH, is essential for the early detection of FH patients, who can then be internally examined and followed-up.

RESUMO

Familial hypercholesterolaemia (FH) is the most common congenital metabolic disorder characterised by the accumulation of lipid particles in the vascular wall thereby leading to premature development of atherosclerosis. It is a serious condition that, if left untreated, can lead to premature death in a cardiovascular event already in the third or fourth decade of life. According to recent studies, the frequency of heterozygotes in the general population is 1: 250, suggesting that there may be up to 40,000 of these patients in the Czech Republic alone. In terms of capturing FH, the Czech Republic belongs to the most successful countries in the world; however, most patients remain undiagnosed. It is essential that these individuals be actively sought for and manifestation of cardiovascular disease (CVD) prevented. There is a therapeutic option that is effective, safe and affordable. The MedPed (Make early diagnosis to Prevent early deaths) project network and a large number of physicians involved in the project represent an effective approach to the diagnosis and treatment of patients with FH. Even though a large proportion of patients with FH are asymptomatic until the manifestation of CVD, it is possible to diagnose FH using a biochemical examination together with a family history. In some patients, it is also possible to identify clinical signs of the disease. Typical ophthalmologic findings include arcus lipoides corneae and xanthelasma palpebrarum. While these are non-specific symptoms, especially if they occur in patients under 50 years of age, they should prompt examination of lipid spectrum parameters. Every patient with (or suspected) familial hypercholesterolaemia should be referred to one of the workplaces of the MedPed project network. Key words: familial hypercholesterolaemia, MedPed, atherosclerosis, xanthelasma palpebrarum, arcus lipoides corneae.

RESUMO

Plasma triglyceride (TG) levels represent a significant risk factor of cardiovascular and total mortality. Concentrations of TG in the plasma depend, to a large extent, on the genetic background, and the apolipoprotein A5 (APOA5) gene seems to be one of the most powerful players in the plasma TG metabolism regulation. In total, we analysed three tagging APOA5 (rs964184 rs662799, rs3135506) SNPs in 209 patients with plasma TG levels over 10 mmol/l (HTG) on at least one occasion and in 379 treatment-naïve controls (NTG) with plasma TG values within the normal range. Minor alleles of all three analysed APOA5 polymorphisms significantly (all P < 0.0001) increased the risk of hypertriglyceridaemia. The most significant association (P < 0.0000001) was observed for the rs964184 polymorphism, where the minor GG homozygotes had the odds ratio (OR, 95% CI) for hypertriglyceridaemia development 21.30 (8.09-56.07, P < 0.000001) in comparison with the major CC allele homozygotes. Carriers of at least one minor allele at rs3135506 had OR (95% CI) 4.19 (2.75-6.40); (P < 0.000005) for HTG development and similarly, carriers of a minor allele at rs662799 had OR (95% CI) 3.07 (2.00-4.72) (P < 0.0001). The cumulative presence of risk alleles (unweighted gene score) significantly differed between patients with episodes of high TG and controls at P < 0.0000001. There were 73 % of subjects without any of the risk alleles among the controls and 46 % in the patients. In contrast, the controls just included 3 % of subjects with score 3 and more in comparison with 18 % in HTG patients. We conclude that common APOA5 variants are very important genetic determinants of episodic hypertriglyceridaemia in the Czech population with a high potential to be applied in personalized medicine.

RESUMO

Familial hypercholesterolemia (FH) is the most common autosomal dominant disorder. It is characterized by a decrease in LDL cholesterol catabolism and an early clinical manifestation of atherosclerotic vessel damage. The aim of the MedPed (Make early diagnosis to Prevent early deaths) project is an early diagnosis of FH patients in order to profit from early treatment and prevent cardiovascular events. Till November 30, 2016 The Czech National MedPed Database has registered 7,001 FH patients from 5,223 different families that is 17.4 % of expected patients in the Czech Republic considering 1:250 FH prevalence. The improvement in diagnostic accuracy, patient cooperation and above all familial cascade screening is enabled by FH mutation detection using the modern technology of next-generation sequencing. FH still remain undiagnosed even though the Czech Republic is one of the most successful countries with respect to FH detection. The opportunities of international collaboration and experience sharing within international programs (e.g. EAS FHSC, ScreenPro FH etc.) will improve the detection of FH patients in the future and enable even more accessible and accurate genetic diagnostics.

RESUMO

Autosomal dominant hypercholesterolemia (ADH), more known as familial hypercholesterolemia (FH), is a lipid metabolism disorder characterized by an elevation in low-density lipoprotein cholesterol (LDL-C) and increased risk for cardiovascular disease. In this study, we assessed a spectrum of mutations causing ADH in 3914 unrelated Czech patients with clinical diagnosis of hypercholesterolemia. Samples have been collected within the framework of the MedPed project running in the Czech Republic since 1998. So far we have found 432 patients (11.0 %) with the APOB gene mutation p.(Arg3527Gln) and 864 patients (22.1 %) with the LDLR gene mutation. In 864 probands carrying the LDLR gene mutation, 182 unique allelic variants were detected. We have identified 14 patients homozygous for mutations in the LDLR or APOB genes. We performed function analyses of p.(Leu15Pro) and p.(Gly20Arg) sequence variations.

RESUMO

This article describes the evolution of our understanding of familial hypercholesterolemia (FH) in the Central, Eastern, and Southern Europe (CESE) region, and the dissemination of this understanding to other countries. Using the ScreenPro FH project as an example, we would like to illustrate the progression from national objectives, to regional networking and, finally, to international collaboration via the Familial Hypercholesterolemia Studies Collaboration (FHSC) project under the leadership of the European Atherosclerosis Society (EAS). It is essential to improve our ability to diagnose FH. In this regard, the EAS and its FHSC project must be commended for their educational and organizational activities which, above all, are dedicated to the creation of a global FH patient registry. In the CESE region, FH diagnostics and treatment situation are markedly different than in Western Europe or North America. Since the Czech MedPed project (Make Early Diagnoses to Prevent Early Deaths in Medical Pedigrees) has been so successful (with results not only comparable to, but, for some parameters, even surpassing the results of many Western countries) we decided to apply the Czech experience to the CESE region. Thus, the ScreenPro FH project was created. The aim of ScreenPro FH is to create a specialist network in the CESE region. The primary objective of the ScreenPro FH project was to dramatically reduce the number of premature deaths due to clinical complications of atherosclerosis in FH patients. At present, ScreenPro FH comprises 18 member countries with a total population of 500,000,000; which, in terms of the FH population, represents 1-2 million patients.

RESUMO

Some patients are susceptible to statin-associated myopathy (SAM) either because of genetic variations affecting statin uptake and metabolism, or because they predispose their carriers to muscular diseases. Among the frequent variants examined using the genome-wide association study approach, SLCO1B1 c.521T>C represents the only validated predictor of SAM in patients treated with high-dose simvastatin. Our aim was to ascertain the overall contribution of large copy-number variations (CNVs) to SAM diagnosed in 86 patients. CNVs were detected by whole genome genotyping using Illumina HumanOmni2.5 Exome BeadChips. Exome sequence data were used for validation of CNVs in SAM-related loci. In addition, we performed a specific search for CNVs in the SLCO1B region detected recently in Rotor syndrome subjects. Rare deletions possibly contributing to genetic predisposition to SAM were found in two patients: one removed EYS associated previously with SAM, the other was present in LARGE associated with congenital muscular dystrophy. Another two patients carried deletions in CYP2C19, which may predispose to clopidogrel-statin interactions. We found no common large CNVs potentially associated with SAM and no CNVs in the SLCO1B locus. Our findings suggest that large CNVs do not play a substantial role in the etiology of SAM.

RESUMO

3-hydroxy-3-methylglutaryl-coenzyme A (HMG-CoA) reductase inhibitors (statins) are widely used drugs for lowering blood lipid levels and preventing cardiovascular diseases. However, statins can have serious adverse effects, which may be related to development of mitochondrial dysfunctions. The aim of study was to demonstrate the in vivo effect of high and therapeutic doses of statins on mitochondrial respiration in blood platelets. Model approach was used in the study. Simvastatin was administered to rats at a high dose for 4 weeks. Humans were treated with therapeutic doses of rosuvastatin or atorvastatin for 6 weeks. Platelet mitochondrial respiration was measured using high-resolution respirometry. In rats, a significantly lower physiological respiratory rate was found in intact platelets of simvastatin-treated rats compared to controls. In humans, no significant changes in mitochondrial respiration were detected in intact platelets; however, decreased complex I-linked respiration was observed after statin treatment in permeabilized platelets. We propose that the small in vivo effect of statins on platelet energy metabolism can be attributed to drug effects on complex I of the electron transport system. Both intact and permeabilized platelets can be used as a readily available biological model to study changes in cellular energy metabolism in patients treated with statins.

RESUMO

AIM: Cardiovascular disease (CVD) is a major cause of morbidity and mortality in developed countries. This study aimed to confirm the effect of common putative CVD-associated gene variants (FTO rs17817449, KIF6 rs20455, 9p21 rs10757274 and 2q36.3 rs2943634) on CVD manifestation, and determine whether this effect differs between younger (< 50 years) and older CVD patients. METHODS: 1191 controls and 1889 MI patients were analyzed. All participants were Caucasian Czech males aged <65 years (532 were <50 years) who were examined at cardiology clinics in Prague, Czech Republic. Variants of FTO, 9p21, 2q36.3, and KIF-6 were genotyped using PCR-RFLP or TaqMan assay. RESULTS: Variants of FTO (OR 1.48; 95% CI, 1.19-1.84 in a TT vs. GG comparison, p=0.0005); 9p21 (OR 1.74; 95% CI, 1.41-2.14 in an AA vs. GG comparison, p=0.0001); and 2q36.3 (OR 1.34; 95%CI, 1.09-1.65 in an AA vs. +C comparison, p=0.006) were significantly associated with MI in the male Czech population. In contrast, genotype frequencies of KIF-6 (rs20455) were the same in patients and controls (P=1.00). Nearly identical results were observed when a subset of young MI patients (N=532, aged <50 years) was analyzed. CONCLUSION: We confirmed the importance of determining FTO, 9p21, and 2q36.3 variants as part of the genetic determination of MI risk in the Czech male population.

RESUMO

Hypertriglyceridemia is an important marker of increased levels of highly atherogenic remnant-like particles. The importance of lowering plasma levels of triglycerides (TG) has been called into question many times, but currently it is considered an integral part of residual cardiovascular risk reduction strategies. Lifestyle changes (improved diet and increased physical activity) are effective TG lowering measures. Pharmacological treatment usually starts with statins, although associated TG reductions are typically modest. Fibrates are currently the drugs of choice for hyperTG, frequently in combination with statins. Niacin and omega-3 fatty acids improve control of triglyceride levels when the above measures are inadequately effective. Some novel therapies including anti-sense oligonucleotides and inhibitors of microsomal triglyceride transfer protein have shown significant TG lowering efficacy. The current approach to the management of hypertriglyceridemia is based on lifestyle changes and, usually, drug combinations (statin and fibrate and/or omega-3 fatty acids or niacin).

RESUMO

The issue of plasma triglyceride levels relative to the risk of development of cardiovascular disease, as well as overall mortality, has been actively discussed for many years. Like other cardiovascular disease risk factors, final plasma TG values have environmental influences (primarily dietary habits, physical activity, and smoking), and a genetic predisposition. Rare mutations (mainly in the lipoprotein lipase and apolipoprotein C2) along with common polymorphisms (within apolipoprotein A5, glucokinase regulatory protein, apolipoprotein B, apolipo-protein E, cAMP responsive element binding protein 3-like 3, glycosylphosphatidylinositol-anchored HDL-binding protein 1) play an important role in determining plasma TG levels.

RESUMO

Statin-associated myopathy (SAM) represents a broad spectrum of disorders from insignificant myalgia to fatal rhabdomyolysis. Its frequency ranges from 1-5 % in clinical trials to 15-20 % in everyday clinical practice. To a large extent, these variations can be explained by the definition used. Thus, we propose a scoring system to classify statin-induced myopathy according to clinical and biochemical criteria as 1) possible, 2) probable or 3) definite. The etiology of this disorder remains poorly understood. Most probably, an underlying genetic cause is necessary for overt SAM to develop. Variants in a few gene groups that encode proteins involved in: i) statin metabolism and distribution (e.g. membrane transporters and enzymes; OATP1B1, ABCA1, MRP, CYP3A4), ii) coenzyme Q10 production (e.g. COQ10A and B), iii) energy metabolism of muscle tissue (e.g. PYGM, GAA, CPT2) and several others have been proposed as candidates which can predispose to SAM. Pharmacological properties of individual statin molecules (e.g. lipophilicity, excretion pathways) and patients´ characteristics influence the likelihood of SAM development. This review summarizes current data as well as our own results.

RESUMO

Obesity is a strong cardiometabolic (CM) risk factor in children. We tested potential CM risk in obese/overweight children and the effect of an intensive lifestyle intervention using newer CM markers: atherogenic index of plasma AIP [Log(TG/HDL-C)], apoB/apoAI ratio and a marker of insulin resistance HOMA-IR. The participants (194 girls, 115 boys, average age 13) were enrolled in an intensive, one-month, inpatient weight reduction program. The program consisted of individualised dietary changes and the exercise program comprised aerobic and resistance training. Anthropometrical and biochemical parameters in plasma and CM risk biomarkers - (AIP, apoB/apoAI ratio and HOMA-IR) were examined before and after the intervention. AIP and HOMA-IR significantly correlated with BMI while apoB/apoAI ratio did not. Only AIP and HOMA-IR showed systematic increases according to the level of obesity by BMI quartiles. Lifestyle intervention significantly improved anthropometrical and biochemical values and the biomarkers too. The response of lipid parameters to the intervention was considerably higher in boys than in girls. The children were stratified into three risk categories according to AIP, where 13.8 % of boys and 5.3 % of girls fell into high risk category. The monitored biomarkers may complement each other in the prognosis of CM risk. AIP was strongly related to obesity and to lipid and glycid metabolism, while the relationship of the apoB/apoAI ratio to obesity and glycid metabolism was not significant. The obese children benefited from the intensive lifestyle intervention which improved the anthropometrical and biochemical parameters and CM risk biomarkers.

RESUMO

This position statement of the Executive Committee of the Czech Society for Atherosclerosis (CSAT) summarizes the most important aspects and novelties of the latest European guidelines for the management of dyslipidemia. In particular the position statement comments on: cardiovascular risk stratification, indications for plasma lipid and lipoprotein levels assessment as well as target lipid values, evaluation of current options for both lifestyle and pharmacological treatment of lipid metabolism disorders and, also, recommendation for laboratory monitoring of patients treated with lipid lowering agents. The statement deals with actual concepts of management of dyslipiemia in everyday practice, e.g. therapy of dyslipidemia in special patients´ groups. This statement does not replace the latest guidelines but focuses on the changes from the former guidelines for dyslipidemia management, published by CSAT in 2007.

RESUMO

OBJECTIVES: This study aimed to determine whether there is a relationship between common FTO (rs17817449) and MC4R (rs17782313) gene variants and body mass reduction or weight loss after a one-month lifestyle intervention in overweight/obese children. DESIGN AND METHODS: We genotyped 357 unrelated non-diabetic Czech children (age 13.7 ± 4.9 years, average BMI at baseline 30.8 ± 4.6 kg/m(2)). Biochemical and anthropometrical measurements were performed before and after 4 weeks of lifestyle interventions (comprising a reduction in energy intake to the age-matched optimum and a supervised exercise program consisting of 5 exercise units per day, 50 min each). RESULTS: The mean weight loss achieved was 6.2 ± 2.1 kg (P<0.001). Significant associations were found between a BMI decrease and the FTO and MC4R variants. Carriers of the FTO GG genotype and/or MC4R CC genotype lost significantly more body weight compared to noncarriers (P<0.0009 for BMI and P<0.002 for body weight). These differences remained significant following adjustment for sex, age and baseline values (P=0.004 for BMI and P=0.01 for body weight). CONCLUSIONS: FTO and MC4R gene variants modify the impact of an intensive lifestyle intervention on BMI decrease in overweight/obese children. Carriers of the FTO GG genotype and MC4R CC genotype benefit significantly more from the lifestyle intervention.

RESUMO

Statins are the most commonly used drugs in patients with dyslipidemia. Among the patients, a significant inter-individual variability with supposed strong genetic background in statin treatment efficacy has been observed. Genome wide screenings detected variants within the CELSR2/PSRC1/SORT1, CILP2/PBX4, APOB, APOE/C1/C4, HMGCoA reductase, LDL receptor and PCSK9 genes that are among the candidates potentially modifying response to statins. Ten variants (SNPs) within these genes (rs599838, rs646776, rs16996148, rs693, rs515135, rs4420638, rs12654264, rs6511720, rs6235, rs11206510) were analyzed in 895 (46 % men, average age 60.3+/-13.1 years) patients with dyslipidemia treated with equipotent doses of statins (~90 % on simvastatin or atorvastatin, doses 10 or 20 mg) and selected 672 normolipidemic controls (40 % men, average age 46.5 years). Lipid parameters were available prior to the treatment and after 12 weeks of therapy. Statin treatment resulted in a significant decrease of both total cholesterol (7.00+/-1.53-->5.15+/-1.17 mmol/l, P<0.0001) and triglycerides (2.03+/-1.01-->1.65+/-1.23 mmol/l, P<0.0005). Rs599838 variant was not detected in first analyzed 284 patients. After adjustment for multiple testing, there was no significant association between individual SNPs and statin treatment efficacy. Only the rs4420638 (APOE/C1/C4 gene cluster) G allele carriers seem to show more profitable change of HDL cholesterol (P=0.007 without and P=0.06 after adjustment). Results demonstrated that, although associated with plasma TC and LDL cholesterol per se, variants within the CELSR2/PSRC1/SORT1, CILP2/PBX4, APOB, APOE/C1/C4, HMGCoA reductase, LDL receptor and PCSK9 genes do not modify therapeutic response to statins.

RESUMO

We shall open our overview of issues related to obesity and hyperlipoproteinemia (HLP) or dyslipidemia with a notoriously known truth (that some are still reluctant to accept): HLP/DLP is not obesity. It is certainly not possible to put an equal sign between subcutaneous fat and the level of plasma lipids and lipoproteins. On the other hand, it is obvious that there is a number of connecting links between HLP/DLP and obesity. These associations on one side and differences on the other are the focus of this review paper. (1) HLP/DLP as well as obesity represent a group of high incidence metabolic diseases (gradually evolving from epidemic to pandemic) that affect several tens of percent of inhabitants. (2) Both HLP/DLP and obesity often occur concurrently, often as a result of unhealthy lifestyle. However, genetic factors are also been studies and it is possible that mutual predispositions for the development of both diseases will be identified. At present, it is only possible to conclude that obesity worsens lipid metabolism in genetically-determined HLP. (3) Both these metabolic diseases represent a risk factor for other pathologies, cardiovascular diseases are the most important common complication of both conditions (central type of obesity only). Concurrent presence of HDL/DLP and obesity is often linked to other diagnoses, such as type 2 diabetes mellitus (DM2T), hypertension, pro-coagulation or pro-inflammatory states; all as part of so called metabolic syndrome. (4) Patients with metabolic syndrome and, mainly, central obesity usually have typical dyslipidemia with reduced HDL-cholesterol (HDL-C) and sometimes hypertriglyceridaemia. Current treatment of HDL/DLP aims to first impact on the primary aim, i.e. LDL-cholesterol (LDL-C), and than influence HDL-C. (5) It seems that the therapeutic efforts in HLP/DLP and obesity will go in the same direction. I will skip the trivial (and difficult to accept by patients) dietary changes. Pharmacotherapy, however, (very scarce with respect to obesity) may bring positive effects on lipids and BMI. Metformin used to be considered as a drug that could improve lipid profile and lead to body weight reduction. Even though larger studies did not provide an unambiguous evidence for this, metformin keeps its position as a first line oral antidiabetic (not only) in patients with T2DM, HLP and obesity. Positive effect on lipids, mainly HDL-C is reported with pioglitazone. This drug, unlike other glitazones, does not bring body weight reduction but at least does not have a negative effect. Other antidiabetics with a positive effect on lipids and body weight include incretins, liraglutid in particular. Liraglutid importantly decreases triglyceride levels and has anorectic effect. Furthermore, metabolic effects of bariatric surgery should not be overlooked. Bariatric surgery brings weight reduction as well as it improves lipid profile and compensation of diabetes mellitus (DM). It should be mentioned here that bariatric surgery has been used for the treatment of HLP as early as 1980s. The results of the 25-year follow up within the POSCH study (ideal bypass indicated for HLP), presented in 2010, confirm a decrease in overall as well as cardiovascular mortality in an operated group, even though patients who did not undergo surgery were significantly more frequently treated with statins.
