Physical signs and atherosclerotic cardiovascular disease in familial hypercholesterolemia: the HELLAS-FH Registry.

AIMS: Three physical signs, namely tendon xanthomas, corneal arcus and xanthelasma, have been associated with heterozygous familial hypercholesterolemia (heFH). The prevalence and clinical significance of these signs are not well established among contemporary heFH individuals. This study explored the frequency as well as the association of these physical signs with prevalent atherosclerotic cardiovascular disease (ASCVD) in heFH individuals. METHODS: Data from the Hellenic Familial Hypercholesterolemia Registry were applied for this analysis. The diagnosis of heFH was based on the Dutch Lipid Clinic Network Score. Multivariate logistic regression analysis was conducted to examine the association of heFH-related physical signs with prevalent ASCVD. RESULTS: Adult patients ( n  = 2156, mean age 50 ±â€Š15 years, 47.7% women) were included in this analysis. Among them, 14.5% had at least one heFH-related physical sign present. The prevalence of corneal arcus before the age of 45 years was 6.6%, tendon xanthomas 5.3%, and xanthelasmas 5.8%. Among physical signs, only the presence of corneal arcus before the age of 45 years was independently associated with the presence of premature coronary artery disease (CAD). No association of any physical sign with total CAD, stroke or peripheral artery disease was found. Patients with physical signs were more likely to receive higher intensity statin therapy and dual lipid-lowering therapy, but only a minority reached optimal lipid targets. CONCLUSION: The prevalence of physical signs is relatively low in contemporary heFH patients. The presence of corneal arcus before the age of 45 years is independently associated with premature CAD.

Obesity and atherosclerotic cardiovascular disease in adults with heterozygous familial hypercholesterolemia: An analysis from HELLAS-FH registry.

BACKGROUND: Familial hypercholesterolemia (FH) and obesity are well-established risk factors of atherosclerotic cardiovascular disease (ASCVD). Despite high prevalence, their joint association with ASCVD remains largely unknown. OBJECTIVE: To investigate the association of obesity with prevalent ASCVD in individuals with heterozygous FH (HeFH) enrolled in the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH). METHODS: FH diagnosis was based on Dutch Lipid Clinic Network (DLCN) criteria. Adults with at least possible FH diagnosis (DLCN score ≥3) and available body mass index (BMI) values were included. Homozygous FH individuals were excluded. RESULTS: 1655 HeFH adults (mean age 51.0 ± 14.4 years, 48.6% female) were included; 378 (22.8%) and 430 (26.0%) were diagnosed with probable and definite FH, respectively. Furthermore, 371 participants (22.4%) had obesity and 761 (46.0%) were overweight. Prevalence of ASCVD risk factors increased progressively with BMI. Prevalence of coronary artery disease (CAD) was 23.4% (3.2% for stroke and 2.7% for peripheral artery disease [PAD]), and increased progressively across BMI groups. After adjusting for traditional ASCVD risk factors and lipid-lowering medication, individuals with obesity had higher odds of established CAD (OR: 1.54, 95% CI: 1.04-2.27, p = 0.036) as well as premature CAD (OR: 1.74, 95% CI: 1.17-2.60, p = 0.009) compared with those with normal BMI. No association was found with stroke or PAD. CONCLUSIONS: Over half of adults with HeFH have overweight or obesity. Obesity was independently associated with increased prevalence of CAD in this population.

Familial Hypercholesterolemia in the Elderly: An Analysis of Clinical Profile and Atherosclerotic Cardiovascular Disease Burden from the Hellas-FH Registry.

BACKGROUND: Familial hypercholesterolemia (FH) carries a high risk of atherosclerotic cardiovascular disease (ASCVD). As the population ages, the age-related influence on clinical characteristics and outcomes becomes increasingly pertinent. This cross-sectional analysis from the HELLAS-FH registry aims to explore potential differences in clinical characteristics, treatment, ASCVD, and goal achievement between those younger and older than 65 years with FH. RESULTS: A total of 2273 adults with heterozygous FH (51.4% males) were studied. Elderly FH patients (n = 349) had a higher prevalence of ASCVD risk factors, such as hypertension (52.1% vs. 20.9%, p < 0.05) and type 2 diabetes (16.9% vs. 6.0%, p < 0.05), compared to younger patients (n = 1924). They also had a higher prevalence of established ASCVD (38.4% vs. 23.1%, p < 0.001), particularly CAD (33.0% vs. 20.2%, p < 0.001), even after adjusting for major ASCVD risk factors. Elderly patients were more frequently and intensively receiving lipid-lowering treatment than younger ones. Although post-treatment LDL-C levels were lower in elderly than younger patients (125 vs. 146 mg/dL, p < 0.05), both groups had similar attainment of the LDL-C target (3.7% vs. 3.0%). CONCLUSIONS: Elderly FH patients have a higher prevalence of ASCVD, particularly CAD. Despite more aggressive treatment, the achievement of LDL-C targets remains very poor. These results emphasize the importance of early FH diagnosis and treatment in reducing ASCVD.

Association between lipoprotein(a) concentrations and atherosclerotic cardiovascular disease risk in patients with familial hypercholesterolemia: an analysis from the HELLAS-FH.

AIMS: Lipoprotein(a) [Lp(a)] is an independent risk factor for atherosclerotic cardiovascular disease (ASCVD) in the general population. However, such a role in patients with familial hypercholesterolemia (FH) is less documented. The purpose of this study was to evaluate the association between Lp(a) concentrations and ASCVD prevalence in adult patients with FH. METHODS: This was a cross-sectional study from the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH). Patients were categorized into 3 tertiles according to Lp(a) levels. RESULTS: A total of 541 adult patients (249 males) with possible/probable/definite FH heterozygous FH (HeFH) were included (mean age 48.5 ± 15.0 years at registration, 40.8 ± 15.9 years at diagnosis). Median (interquartile range) Lp(a) concentrations in the 1st, 2nd and 3rd Lp(a) tertile were 6.4 (3.0-9.7), 22.4 (16.0-29.1) and 77.0 (55.0-102.0) mg/dL, respectively. There was no difference in lipid profile across Lp(a) tertiles. The overall prevalence of ASCVD was 9.4% in the first, 16.1% in the second and 20.6% in the third tertile (p = 0.012 among tertiles). This was also the case for premature ASCVD, with prevalence rates of 8.5, 13.4 and 19.8%, respectively (p = 0.010 among tertiles). A trend for increasing prevalence of coronary artery disease (8.3, 12.2 and 16.1%, respectively; p = 0.076 among tertiles) was also observed. No difference in the prevalence of stroke and peripheral artery disease was found across tertiles. CONCLUSIONS: Elevated Lp(a) concentrations are significantly associated with increased prevalence of ASCVD in patients with possible/probable/definite HeFH.

Prevalence of Diabetes and Its Association with Atherosclerotic Cardiovascular Disease Risk in Patients with Familial Hypercholesterolemia: An Analysis from the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH).

Familial hypercholesterolemia (FH) and type 2 diabetes mellitus (T2DM) are both associated with a high risk of atherosclerotic cardiovascular disease (ASCVD). Little is known about the prevalence of T2DM and its association with ASCVD risk in FH patients. This was a cross-sectional analysis from the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH) including adults with FH (n = 1719, mean age 51.3 ± 14.6 years). Of FH patients, 7.2% had a diagnosis of T2DM. The prevalence of ASCVD, coronary artery disease (CAD), and stroke was higher among subjects with T2DM compared with those without (55.3% vs. 23.3%, 48.8% vs. 20.7%, 8.3% vs. 2.7%, respectively, p < 0.001). When adjusted for age, systolic blood pressure, smoking, body mass index, hypertension, waist circumference, triglyceride levels, high-density lipoprotein cholesterol levels, and gender, T2DM was significantly associated with prevalent ASCVD [OR 2.0 (95% CI 1.2−3.3), p = 0.004]. FH patients with T2DM were more likely to have undergone coronary revascularization than those without (14.2% vs. 4.5% for coronary artery bypass graft, and 23.9% vs. 11.5% for percutaneous coronary intervention, p < 0.001). T2DM is associated with an increased risk for prevalent ASCVD in subjects with FH. This may have implications for risk stratification and treatment intensity in these patients.

LDL cholesterol target achievement in heterozygous familial hypercholesterolemia patients according to 2019 ESC/EAS lipid guidelines: Implications for newer lipid-lowering treatments.

BACKGROUND: The 2019 European guidelines (ESC/EAS) for the treatment of dyslipidaemias recommend more aggressive targets for low-density lipoprotein cholesterol (LDL-C) in patients with familial hypercholesterolemia (FH). Current lipid-lowering treatment is often inadequate to achieve these targets. METHODS: Data from the HELLAS-FH registry were analysed to assess achievement of LDL-C targets in adults with FH based on the 2019 ESC/EAS guidelines. In patients who had not achieved LDL-C target, the maximally reduced LDL-C value was calculated after theoretical switch to rosuvastatin/ezetimibe 40/10 mg/day. The percentage of patients who remained candidates for proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) was then calculated. RESULTS: Patients (n = 1694, mean age 50.8 ± 14.7 years) had LDL-C levels 242 ± 71 mg/dL (6.3 ± 1.8 mmol/L) at diagnosis. Most treated patients were receiving statins (97.5%) and about half were on additional ezetimibe (47.5%). Based on the 2019 ESC/EAS guidelines the percentage of patients achieving LDL-C goals was only 2.7%. Following theoretical up titration to rosuvastatin/ezetimibe 40/10 mg, LDL-C target achievement rate would increase to 5.9%. In this scenario, most patients (55.9%) would be eligible for PCSK9i treatment. Following theoretical administration of a PCSK9i, LDL-C target achievement rate would rise to 57.6%. However, 42.4% of patients would still be eligible for further LDL-C lowering treatment. CONCLUSIONS: Most FH patients do not reach new LDL-C targets even if on maximum intensity statin/ezetimibe treatment. In this case, more than half of FH patients are candidates for PCSK9i therapy and a considerable proportion may still require additional LDL-C lowering.

Prevalence of Non-coronary Heart Disease in Patients with Familial Hypercholesterolemia: An Analysis from the HELLAS-FH.

AIMS: Despite the established link between familial hypercholesterolemia (FH) and increased risk of coronary heart disease (CHD), its association with other common atherosclerotic and metabolic diseases has not been extensively studied. The aim of this study was to report the prevalence of peripheral arterial disease (PAD) [i.e., common carotid artery disease (CCAD) and lower extremity arterial disease (LEAD)], aortic valve stenosis, chronic kidney disease (CKD) and non-alcoholic fatty liver disease (NAFLD) in patients with FH. MATERIALS & METHODS: This was a cross-sectional study retrieving data from the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH). RESULTS: A total of 1,633 adult patients (850 males) with heterozygous FH (HeFH) were included (mean age 51.3±14.6 years at registration and 44.3±15.9 years at diagnosis). Any common carotid artery stenosis (CCAS) was diagnosed in 124 out of 569 patients with available related data (21.8%), while the prevalence of CCAD (defined as a CCAS ≥50%) was 4.2%. The median (interquartile range - IQR) CCAS was 30% (20-40), whereas the median (IQR) carotid intima-media thickness (CIMT) was 0.7 (0.1-1.4) mm. LEAD was reported in 44 patients (prevalence 2.7%). The prevalence of aortic valve stenosis and CKD was 2.0% and 6.4%, respectively. NAFLD was present in 24% of study participants. CONCLUSION: HeFH is associated with a relatively high prevalence of any CCAS and CCAD. The prevalence of LEAD, CKD and aortic valve stenosis was relatively low, whereas the prevalence of NAFLD was similar to that of the general population.

Achieving low-density lipoprotein cholesterol targets as assessed by different methods in patients with familial hypercholesterolemia: an analysis from the HELLAS-FH registry.

BACKGROUND: Familial hypercholesterolemia (FH) is characterized by elevated low-density lipoprotein cholesterol (LDL-C) levels and increased cardiovascular disease (CVD) risk. FH patients often have increased lipoprotein(a) [Lp(a)] levels, which further increase CVD risk. Novel methods for accurately calculating LDL-C have been proposed. METHODS: Patients with FH were recruited by a network of Greek sites participating in the HELLAS-FH registry. LDL-C levels were calculated using the Friedewald (LDL-CF) and the Martin/Hopkins (LDL-CM/H) equations as well as after correcting LDL-CM/H for Lp(a) levels [LDL-CLp(a)corM/H]. The objective was to compare LDL-C levels and target achievement as estimated by different methods in FH patients. RESULTS: This analysis included 1620 patients (1423 adults and 197 children). In adults at diagnosis, LDL-CF and LDL-CM/H levels were similar [235 ± 70 mg/dL (6.1 ± 1.8 mmol/L) vs 235 ± 69 mg/dL (6.1 ± 1.8 mmol/L), respectively; P = NS], while LDL-CLp(a)corM/H levels were non-significantly lower than LDL-CF [211 ± 61 mg/dL (5.5 ± 1.6 mmol/L); P = 0.432]. In treated adults (n = 966) both LDL-CF [150 ± 71 mg/dL (3.9 ± 1.8 mmol/L)] and LDL-CM/H levels [151 ± 70 mg/dL (6.1 ± 1.8 mmol/L); P = 0.746] were similar, whereas LDL-CLp(a)corM/H levels were significantly lower than LDL-CF [121 ± 62 mg/dL (3.1 ± 1.6 mmol/L); P < 0.001]. Target achievement as per latest guidelines in treated patients using the LDL-CM/H (2.5%) and especially LDL-CLp(a)corM/H methods (10.7%) were significantly different than LDL-CF (2.9%; P < 0.001). In children, all 3 formulas resulted in similar LDL-C levels, both at diagnosis and in treated patients. However, target achievement by LDL-CF was lower compared with LDL-CM/H and LDL-CLp(a)corM/H methods (22.1 vs 24.8 vs 33.3%; P < 0.001 for both comparisons). CONCLUSION: LDL-CLp(a)corM/H results in significantly lower values and higher target achievement rate in both treated adults and children. If validated in clinical trials, LDL-CLp(a)corM/H may become the method of choice to more accurately estimate 'true' LDL-C levels in FH patients.

Emerging Fixed-Dose Combination Treatments for Hyperlipidemia.

Low-density lipoprotein cholesterol targets may not be achieved by statin monotherapy, especially in high-risk patients. Furthermore, in some patient subgroups, atherogenic dyslipidemia is observed. As a result, a combination of a statin with other hypolipidemic drugs may have additional benefits, especially in the form of a single tablet. The aim of this review is to present the novel fixed-dose drug combinations for the management of hyperlipidemia. Statins, ezetimibe, and fibrates have established their efficacy and safety in the treatment of hypercholesterolemia and hypertriglyceridemia. Clinical trials have shown that these hypolipidemic drug classes can be safely combined in order to augment the lipid-lowering efficacy. Furthermore, novel hypolipidemic drugs such as bembedoic acid and berberine have shown some promising initial results. The combination of different hypolipidemic regimens in a fixed-dose formulation can enhance the adherence to hypolipidemic treatment leading to improved outcomes. Moreover, complementary mechanisms of action of the combined hypolipidemic drugs may also provide additional benefits such as improvement in carbohydrate metabolism. As a result, fixed-dose combinations of hypolipidemic agents may provide an attractive option for the effective and safe management of hypercholesterolemia.

Characteristics and management of 1093 patients with clinical diagnosis of familial hypercholesterolemia in Greece: Data from the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH).

BACKGROUND AND AIMS: Although familial hypercholesterolemia (FH) is one of the most common genetic disorders, it remains largely underdiagnosed and undertreated. The Hellenic Atherosclerosis Society has established the Hellenic Familial Hypercholesterolemia (HELLAS-FH) Registry, part of the Familial Hypercholesterolemia Studies Collaboration (FHSC), to evaluate the characteristics and management of patients with FH in Greece. METHODS: Patients with diagnosed FH were recruited by a network of sites throughout Greece. The prevalence of cardiovascular disease (CVD) risk factors, as well as management of FH, was recorded. RESULTS: This interim analysis included 1093 patients (556 male; 950 adults). The median age of FH diagnosis was 42.2 years (interquartile range 27.2-53.0). A family history of CVD was present in 47.8%, while 21.1% of patients had a personal history of CVD. At diagnosis, low-density lipoprotein cholesterol (LDL-C) was 241 ±â€¯76 mg/dL in adults and 229 ±â€¯57 mg/dL in children. Overall, 63.1% of the patients were receiving hypolipidemic drug treatment, mainly statins, at inclusion in the registry. Mean LDL-C of patients receiving drug treatment was 154 ±â€¯76 mg/dL in adults and 136 ±â€¯47 mg/dL in children. The majority of treated patients (87.9%) did not achieve LDL-C targets. CONCLUSIONS: FH in Greece is characterized by a significant delay in diagnosis and a high prevalence of both family and personal history of established CVD. The vast majority of FH patients do not achieve LDL-C targets. Improved awareness and management of FH are definitely needed.

Effects of PCSK9 Inhibitors on Other than Low-Density Lipoprotein Cholesterol Lipid Variables.

Low-density lipoprotein cholesterol (LDL-C) is a major cardiovascular risk factor, but other lipid variables such as triglycerides (TRGs), high-density lipoprotein cholesterol (HDL-C) and lipoprotein a [Lp(a)] also affect cardiovascular risk. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors significantly lower LDL-C concentration but also modestly improve the concentrations of TRGs and HDL-C and more robustly decrease Lp(a) levels. The review presents the associated mechanisms of the beneficial effects of PCSK9 inhibitors on the other than LDL-C lipid variables, including the effects on lipid/apolipoprotein secretion and clearance and the heteroexchange between lipoproteins, as well as the possible effects on other variables involved in lipid metabolism such as sortilin. Proprotein convertase subtilisin/kexin type 9 inhibitors improve the overall lipid profile, and these beneficial effects may play a role in the reduction of cardiovascular risk.

Pharmacokinetic drug evaluation of empagliflozin plus linagliptin for the treatment of type 2 diabetes.

INTRODUCTION: Type 2 diabetes mellitus has become a growing epidemic and therefore efficient treatment strategies that target its management are needed. The treatment of diabetic patients often requires the combination of antidiabetic drug classes. Sodium-glucose co-transporter 2 inhibitors (SGLT2i) block glucose reabsorption in the proximal renal tubules. Dipeptidyl peptidase-4 inhibitors (DPP-4i) improve glucose metabolism by blocking the enzyme that degrades incretins leading to increased insulin secretion. Areas covered: The aim of the review is to present the available data on pharmacokinetic properties/pharmacodynamics, metabolic and cardiovascular effects of empagliflozin plus linagliptin combination. Expert opinion: Both empagliflozin and linagliptin have established safety and efficacy in the treatment of diabetes. Available data demonstrate the absence of pharmacological interactions when the two drugs are given together. The complementary mechanisms of action would be expected to provide additive benefits on carbohydrate metabolism variables, but the results from clinical trials have shown that the empagliflozin/linagliptin combination provides only mild improvements of glycated hemoglobin compared with either monotherapy. However, the single-tablet formulation of empagliflozin/linagliptin is expected to provide better compliance and thus improved glycaemic control coupled with a favourable safety profile. Thus, the fixed-dose combination of empagliflozin/linagliptin has the capacity to both effectively and safely manage diabetic patients.

An insight into familial hypercholesterolemia in Greece: rationale and design of the Hellenic Familial Hypercholesterolemia Registry (HELLAS-FH).

Familial hypercholesterolemia (FH) is the most common metabolic genetic disorder. It is estimated that around 13 million people worldwide have FH. At the same time, only 25% of FH patients have been diagnosed. Moreover, these patients are often undertreated. The true prevalence of FH in Greece is unknown, but it is estimated that there are at least 40,000 FH patients nationwide pointing to a prevalence of 1:250. Patients with FH are at a high risk for cardiovascular events and death at an early age. Therefore, prompt detection of these patients is of pivotal importance in order to implement appropriate preventive measures at a young age. Patient registries are a powerful tool for recording and monitoring a disease and promoting clinical practices, thus contributing to improved outcomes and reduction of healthcare costs. National registries of FH patients have been a success in the Netherlands, Spain and Wales. As Greece did not have a national FH registry, the Hellenic Atherosclerosis Society has organized, established and funded the Hellenic Familial Hypercholesterolemia (HELLAS-FH) national registry in order to promote a better understanding of FH in our country.

Severe hyperkalemia following blood transfusions: Is there a link?

Patients with gastrointestinal bleeding often require large volume blood transfusion. Among the various side effects of blood transfusion, the increase of potassium levels is a serious one which is often overlooked. We report a case of severe hyperkalemia in a patient with gastric bleeding after large volume transfusion of packed red blood cells. The patient had hyperkalemia at baseline associated with his receiving medication as well as acute renal failure following hypovolemia. The baseline hyperkalemia was further aggravated after massive transfusions of packed red blood cells in a short period of time. The associated pathogenetic mechanisms resulting in the increase of potassium levels are presented. A number of risk factors which increase the risk of hyperkalemia after blood transfusion are discussed. Moreover, appropriate management strategies for the prevention of blood transfusion associated hyperkalemia are also presented. Physicians should always keep in mind the possibility of hyperkalemia in cases of blood transfusion.

The current role of thiazolidinediones in diabetes management.

Among the epidemics of modern time, type 2 diabetes mellitus (T2DM) is one of the main contributors to overall morbidity as well as mortality. A number of different treatment options are available for the management of diabetes. Among them thiazolidinediones (TZDs) is an interesting drug class since it does not target the result of T2DM, i.e., hyperglycemia but rather some of the core mechanisms of the disease. Indeed, glitazones increase insulin sensitivity by activating the peroxisome proliferator-activated receptor γ, which plays an important role in regulating various metabolic parameters. Although TZDs have an established efficacy in T2DM treatment, their usage during the past years was questioned following the emergence of some alarming data regarding their safety and especially the cardiovascular safety of rosiglitazone. As a result, there is often some skepticism about the current role of TZDs in T2DM management. This mainly affects rosiglitazone even leading to its withdrawal from several markets in contrast to pioglitazone, which has shown a beneficial cardiovascular profile. A comprehensive assessment of the benefit-to-risk ratio of TZDs is required in order to better understand the place of these drugs in T2DM management.

The effect of rosuvastatin on low-density lipoprotein subfractions in patients with impaired fasting glucose.

BACKGROUND: Prediabetes substantially increases cardiovascular risk. We examined the effect of rosuvastatin on the quantity and quality of low-density lipoprotein cholesterol (LDL-C) in patients with dyslipidemia having impaired fasting glucose (IFG) compared to normoglycemic patients with dyslipidemia. METHODS: This was a prospective observational study including patients with dyslipidemia and IFG (IFG group, n = 49) matched with normoglycemic patients with dyslipidemia (control group, n = 64). Study participants, following dietary intervention, were prescribed rosuvastatin 10 or 20 mg/d to achieve LDL-C goals. Baseline as well as 24 weeks posttreatment changes in the serum lipid profile were evaluated. Moreover, analysis of the LDL subfraction profile was conducted using a polyacrylamide tube gel electrophoresis method. RESULTS: Similar effects were observed in lipid profile in both treatment groups. Patients with IFG experienced a greater decrease in the cholesterol concentration of small dense LDL particles (-65.7%, P < .001 vs baseline) compared to controls (-38.5%, P < .001 vs baseline; P = .018 vs patients with IFG). There was no significant difference in the changes of cholesterol concentration of large and buoyant LDL particles in the IFG group when compared to the control group. A greater increase in the mean LDL particle size (+1.5%, P < .001 vs baseline) was noted in the IFG group compared to the control group at 24 weeks (+0.4%, P = .028 vs baseline; P = .008 vs IFG group). CONCLUSION: Targeting dyslipidemia with rosuvastatin was associated with more favorable changes in the LDL subfraction profile in patients with IFG compared to normoglycemic ones.

Combining rosuvastatin with angiotensin-receptor blockers of different PPARγ-activating capacity: effects on high-density lipoprotein subfractions and associated enzymes.

The effects of combining angiotensin-receptor blockers of different peroxisome proliferator-activated receptor γ-activating capacity with rosuvastatin on high-density lipoprotein (HDL) subfractions and associated enzymes in patients with mixed dyslipidemia, hypertension, and prediabetes were assessed. Patients (n = 151) were randomly allocated to rosuvastatin (10 mg/d) plus telmisartan 80 mg/d (RT group, n = 52) or irbesartan 300 mg/d (RI group, n = 48) or olmesartan 20 mg/d (RO group, n = 51). Total and intermediate HDL cholesterol (HDL-C) levels did not change in any group. Large HDL-C increased, while small HDL-C decreased significantly in all the groups (P = not significant between the groups). The mass of HDL lipoprotein-associated phospholipase A2 (HDL-Lp-PLA2) and the activities of paraoxonase 1 remained unchanged in all the groups. However, HDL-Lp-PLA2 activity increased only in the RT group (+21.4%; P < .01 vs baseline) and did not change in the RI (-4.3%; P = .005 vs RT group) and RO (+3.2%; P = .01 vs RT) groups. In conclusion, only the combination of rosuvastatin with telmisartan increased the possibly antiatherosclerotic HDL-Lp-PLA2 activity.
