RESUMO

Background and Objectives: This study estimates the prevalence and severity of erectile dysfunction and its association with cardiovascular risk factors in patients after a myocardial infarction. Materials and Methods: This study included men aged 35-80 years, diagnosed with myocardial infarction and examined in the Department of Preventive Cardiology of Vilnius University Hospital Santaros Klinikos between 2016 and 2020. Anthropometric characteristics, blood pressure, lipid profile, blood glucose levels and prevalence of cardiovascular risk factors were evaluated. The International Index of Erectile Function-5 was used to assess patients' erectile function. Results: A total of 171 patients were analysed. The mean age was 57.6 ± 8.8 years. Of the patients, 42.1, 25.1 and 11.7% had three, four and five established cardiovascular risk factors, respectively. Of the patients, 100% were diagnosed with dyslipidaemia, 90.0%-arterial hypertension, 14.6%-diabetes, 23.3%-smoking, 43.7%-positive familial history and 54.5%-insufficient physical activity. The overall prevalence of erectile dysfunction was 62%. It was scored mild in 37.4%, mild-to-moderate-15.2%, moderate-5.3% and severe in 4.1% of the patients. The mean age was significantly different between severity groups (p < 0.001). The study demonstrated a negative correlation between age and total score of the questionnaire (r = -0.308, p < 0.001). Arterial hypertension was more frequent in the patients with erectile dysfunction (p = 0.02). Other cardiovascular risk factors were distributed similarly. Conclusions: Erectile dysfunction is common in patients after a myocardial infarction and its severity is age dependent. The prevalence of cardiovascular risk factors is high, with arterial hypertension significantly more frequent in patients with erectile dysfunction.

RESUMO

BACKGROUND: The aim of our study was to evaluate high-density lipoprotein cholesterol (HDL-C) efflux capacity in healthy controls and patients with severe dyslipidemia. Evaluation of HDL function may be beneficial for better understanding of cardiovascular diseases, as well as for taking actions to minimize residual cardiovascular risk. METHODS: During 2016-2017 a total of 93 participants - 48 (51.6%) women and 45 (48.4%) men - were included in this cross-sectional study. Data of 45 (48.4%) participants with severe dyslipidemia (SD) and 48 (51.6%) controls without dyslipidemia was used for statistical analysis. Total lipid panel, concentration of lipoprotein (a) and apolipoproteins were measured, data about cardiovascular risk factors were collected and detailed evaluation of HDL-C quality was performed for all patients. RESULTS: Increased HDL-C concentration was associated with higher ApoA1 (r = 0.866 in controls, r = 0.63 in SD group), ApoA2 (r = 0.41 in controls, r = 0.418 in SD group) and LDL-C concentrations (r = - 0.412 in SD group), lower ApoE (r = - 0.314 in SD group) and TG concentrations (r = - 0.38 in controls, r = - 0.608 in SD group), lower ApoB/ApoA1 ratio (r = - 0.567 in control group), below average HDL-C efflux capacity (r = - 0.335 in SD group), lower BMI (r = - 0.327 in controls, r = - 0.531 in SD group) and abdominal circumference (r = - 0.309 in women with SD). Below-average HDL-C efflux capacity was found in 67.7% (N = 63) of participants. It was more often found among patients with normal weight or BMI 30-31 kg/m2. HDL-C efflux capacity was inversely associated with HDL-C concentration (r = - 0.228). CONCLUSION: Abnormal HDL function may be associated with residual cardiovascular risk in Lithuanian population.

RESUMO

BACKGROUND: Coronary artery calcium (CAC) is known as a reliable tool for estimating risk of myocardial infarction, coronary death, all-cause mortality and is even used to evaluate suitable asymptomatic patients. We therefore aimed to evaluate whether CAC scoring can be applied in the algorithm for clinical examination of patients with severe hypercholesterolemia (SH). METHODS: During the period of 2016-2017 a total of 213 asymptomatic adults, underwent computed tomography angiography to evaluate their CAC scoring. The sample consisted of 110 patients with SH and 103 age and sex matched controls without dyslipidemia and established cardiovascular disease. RESULTS: In total there were 79 (37.2%) subjects with elevated (≥25th) CAC percentiles. Out of them 47 (59.5%) had SH and 32 (40.5%) did not. CAC score did not differ between groups (SH (+) 140.30 ± 185.72 vs SH (-) 87.84 ± 140.65, p = 0.146), however there was a comparable difference in how the participants of these groups distributed among different percentile groups (p = 0.044). Gender, blood pressure, tabaco use, physical activity, family history of coronary artery disease and diabetes mellitus were not associated with CAC score (p > 0.05). There were no significant correlations between biochemical parameters and CAC percentiles except for increase in lipoprotein(a) (p = 0.038). Achilles tendon pathology, visceral obesity, body mass index and increased waist-hip ratio were not associated with CAC percentiles either (p > 0.05). CONCLUSIONS: CAC score is not associated with presence of SH. CAC score is not an appropriate diagnostic tool in the algorithm for clinical examination of patients with SH. Further larger studies are needed to support our findings.

RESUMO

BACKGROUND AND AIMS: Achilles tendon lesions have long been associated with genetic defects in lipid metabolism and increased risk of cardiovascular diseases (CVD). With this study we aimed to evaluate the usefulness of Achilles tendon ultrasonography in identifying people at greater risk among subjects with severe hypercholesterolemia (SH) in a high-risk population. METHODS: During the period of 2016-2017 a total of 213 participants were enrolled in this case-control study. Data of 110 patients with SH and 103 age and sex matched controls without dyslipidaeplemia and established CVD was collected. RESULTS: Achilles tendinopathy (AT) was present in 42.7% of subjects with SH and in 29.1% of controls (p = 0.039). Stronger association between SH and AT was seen in women - 24.1% vs 2.0% (p = 0.001). SH increased odds of AT by 1.815 (95% CI, 1.028-3.206). Prevalence of AT was higher in males despite presence (SH+) or absence (SH-) of severe hypercholesterolemia (SH+ 60.7% vs 24.1%, SH- 55.8% vs 2.0%, p < 0.001). AT was associated with higher proportion of subjects exceeding normal mean values of TC (80.5% vs 52.9%, p = 0.001), LDL-C (76.6% vs 52.2%), TG (54.5% vs. 22.1%), ApoB (57.1% vs 22.2%), ApoE (44.0% vs 22.4%) levels and ApoB/ApoA ratio (46.1% vs 21.5%) (p = 0.001) and family history of premature coronary heart disease (CHD). CONCLUSIONS: AT is more prevalent among subjects with SH and is associated with higher levels of TC, TG, LDL-C, ApoB, ApoE, ApoB/ApoA ratio, family history of premature CHD. SH increases the odds of developing AT.

RESUMO

BACKGROUND AND AIMS: Cardiovascular disease (CVD) is a major cause of premature death in Lithuania where abnormal lipid levels are very common among middle-aged adults. The aim of this study was to evaluate lipid profile in middle-aged Lithuanians and perform population-based severe hypercholesterolaemia (SH) screening. METHODS: This study included men aged 40-54 and women aged 50-64 years without overt CVD, participating in the Lithuanian High Cardiovascular Risk (LitHiR) primary prevention programme during the period 2009-2016. Lipidograms of 92,373 adults (58.4% women and 41.6% men) included in the database were analysed and screening for SH was performed. RESULTS: The mean levels of total cholesterol, LDL cholesterol (LDL-C) and triglycerides (TG) among participants were 6.08 mmol/l, 3.87 mmol/l, and 1.59 mmol/l, respectively. Any type of dyslipidaemia was present in 89.7%, and severe dyslipidaemia in 13.4% of the study population. 80.2% of adults without overt CVD had LDL-C ≥3 mmol/l. SH (LDL-C ≥6 mmol/l) was detected in 3.2% of study participants. Prevalence of SH decreased from 2.91% to 2.82% during the period 2009-2016 (p for trend = 0.003). LDL-C ≥6.5 mmol/l was observed in 1.5% of subjects while both LDL-C ≥6.5 mmol/l, and TG ≤ 1.7 mmol/l was found in 0.6% of subjects. CONCLUSIONS: SH was present in 3.2% of the middle-aged population without overt CVD. Slightly decreasing prevalence of SH was observed during the period 2009-2016 in Lithuania. Likely phenotypic familial hypercholesterolaemia was observed in 1.5% of middle-aged Lithuanians. Further clinical and genetic evaluation of people with SH is needed to detect familial forms of SH.

RESUMO

BACKGROUND: Cardiovascular mortality in Lithuania is extremely high and abnormal lipid levels are very common among Lithuanian adults. Dyslipidemia is one of the main independent risk factors for cardiovascular diseases (CVD) leading to high absolute CVD risk. The aim of this study was to assess CVD risk in dyslipidemic middle-aged subjects. METHODS: During the period of 2009-2016 a total of 92,373 people (58.4% women and 41.6% men) were evaluated. This study included men aged 40-54 and women aged 50-64 without overt CVD. RESULTS: Any type of dyslipidemia was present in 89.7% of all study population. 7.5% of dyslipidemic patients did not have any other conventional risk factors. Three and more risk factors were detected in 60.1% of dyslipidemic subjects. All analyzed risk factors, except smoking, were more common in dyslipidemic adults compared to subjects without dyslipidemia: arterial hypertension (55.8% vs. 43.3%, p < 0.001), diabetes (11.1% vs. 7.3%, p < 0.001), abdominal obesity (45.3% vs. 30.2%, p < 0.001), BMI ≥30 kg/m2 (35.8% vs. 23.7%, p < 0.001), metabolic syndrome (34.0% vs. 9.2%, p < 0.001), family history of coronary heart disease (26.3% vs. 23.1%, p < 0.001), unbalanced diet (62.5% vs. 52.9%, p < 0.001) and insufficient physical activity (52.0% vs. 44.2%, p < 0.001). The prevalence of all evaluated risk factors, except smoking, increased with age. Average SCORE index was 1.87 in all study population, while dyslipidemic subjects had higher SCORE compared to control group (1.95 vs 1.20, p < 0.001). CONCLUSIONS: Almost two thirds of dyslipidemic middle-aged Lithuanian adults without overt cardiovascular disease had three or more other CVD risk factors, which synergistically increase absolute risk of CVD. The average 10-year risk of CVD death in patients with dyslipidemia was 1.95%. The importance of managing dyslipidemia as well as other risk factors in order to reduce burden of cardiovascular disease in Lithuania is evident.

RESUMO

BACKGROUND: Atherogenic dyslipidemia (AD) is a blood serum lipid profile abnormality characterized by elevation of triglycerides and reduced levels of high density lipoprotein cholesterol (HDL-C). It is associated with residual cardiovascular risk. This study evaluated and compared the risk profiles of patients with hypertriglyceridemia, low-HDL-C levels or AD, in order to understand, which lipid profile is associated with greater risk. METHODS: During the period of 2009-2016 a population of 92,373 Lithuanian adults (men 40-54 years old and women 50-64 years old) without overt cardiovascular disease were analyzed. Data of 25,746 patients (68.6% women and 31.4% men) with hypertriglyceridemia and/or low HDL-C low levels were collected and used for further statistical analysis. RESULTS: Participants with AD tend to have more unfavorable risk profile than participants with hypertriglyceridemia or low-HDL-C. AD tends to cluster with other atherogenic risk factors, such as arterial hypertension [odds ratio (OR) 1.96, 95% confidence intervals (CI) 1.87-2.01], smoking [OR 1.20, 95% CI 1.14-1.27], diabetes mellitus [OR 2.74, 95% CI 2.58-2.90], obesity [OR 2.92, 95% CI 2.78-3.10], metabolic syndrome [OR 22.27, 95% CI 20.69-23.97], unbalanced diet [OR 1,59, 95% CI 1.51-1.68], low physical activity [OR 1.80, 95% CI 1.71-1,89], CHD history in first degree relatives [OR 1.18, 95% CI 1.12-1.25] and total number of risk factors [OR 1.47, 95% CI 1.38-1.57]. CONCLUSION: AD is associated with more unfavorable cardiovascular risk profile than hypertriglyceridemia or low-HDL cholesterol levels. Once identified AD should require additional medical attention since it is an important factor of residual cardiovascular risk.

RESUMO

BACKGROUND: Dyslipidemia is highly prevalent and is one of the major risk factors for cardiovascular disease in Lithuania. The purpose of this study was to determine the prevalence of severe dyslipidemia in Lithuanian middle aged primary prevention population and to investigate cardiovascular risk profile. METHODS: The group of 83,376 people were examined in the Lithuanian High Cardiovascular Risk primary prevention program (LitHiR), during 2009-2015 years. This study recruited middle aged men and women without overt cardiovascular disease. The prevalence of cardiovascular risk factors was compared between severe dyslipidemia group and control group. RESULTS: Severe dyslipidemia was present in 13.5% (11265) of the subjects; 66.6% (7508) were females. The subjects with severe dyslipidemia had significantly higher rates of arterial hypertension (63.5% vs. 44.2%, p < 0.001), diabetes mellitus (16% vs. 8.1%, p < 0,001), abdominal obesity (51% vs. 30.3%, p < 0.001), body mass index (BMI) > 30 (kg/m2) (38.8% vs. 24.1%, p < 0.001), metabolic syndrome (47.2% vs. 9.2%, p < 0.001), unbalanced diet (66.5% vs. 53.5%, p < 0.001), insufficient physical activity (56% vs. 44.2%, p < 0.001), family history of cardiovascular disease (29.7% vs. 22.7%, p < 0.001) in comparison with control group. Subjects without dyslipidemia had significantly higher rates of smoking (26.4% vs. 22.7%, p < 0.001). The prevalence of familial hypercholesterolemia was 0.1%, very high hypertriglyceridemia - 0.2% and familial mixed dyslipidemia - 0.1% of the subjects examined in the LitHiR programme. CONCLUSIONS: High prevalence of dyslipidemia remains a major problem in Lithuania. 9 out of 10 people have dyslipidemia, 1 out of 10 - severe dyslipidemia. Severe dyslipidemia is associated with higher frequency of other cardiovascular risk factors.

RESUMO

OBJECTIVE: To investigate the predictive value of different biomarkers for the incidence of type 2 diabetes mellitus (T2DM) in subjects with metabolic syndrome. METHODS: A prospective study of 525 non-diabetic, middle-aged Lithuanian men and women with metabolic syndrome but without overt atherosclerotic diseases during a follow-up period of two to four years. We used logistic regression to develop predictive models for incident cases and to investigate the association between various markers and the onset of T2DM. RESULTS: Fasting plasma glucose (FPG), body mass index (BMI), and glycosylated haemoglobin can be used to predict diabetes onset with a high level of accuracy and each was shown to have a cumulative predictive value. The estimated area under the receiver-operating characteristic curve (AUC) for this combination was 0.92. The oral glucose tolerance test (OGTT) did not show cumulative predictive value. Additionally, progression to diabetes was associated with high values of aortic pulse-wave velocity (aPWV). CONCLUSION: T2DM onset in middle-aged metabolic syndrome subjects can be predicted with remarkable accuracy using the combination of FPG, BMI, and HbA1c, and is related to elevated aPWV measurements.

RESUMO

OBJECTIVE: To investigate the carotid-radial pulse wave velocity, augmentation index, and flow-mediated dilation of the brachial artery and factors possibly influencing them in women with rheumatoid arthritis and systemic lupus erythematosus. MATERIAL AND METHODS: A total of 63 women with rheumatoid arthritis, 31 with systemic lupus erythematosus, and 72 controls, aged 18-55 years, were examined. Parameters of arterial stiffness, augmentation index and carotid-radial pulse wave velocity, were obtained by applanation tonometry (Sphygmocor (v.7.01) AtCor Medical). Flow-mediated dilatation of the brachial artery, reflecting endothelial function was determined by ultrasound system (Logiq 7, General Electric). RESULTS: The groups of women with rheumatoid arthritis and systemic lupus erythematosus lupus differed from controls regarding augmentation index (P<0.001; P=0.008) and did not differ between each other. Women with systemic lupus erythematosus differed from controls regarding pulse wave velocity (P=0.018), while women with rheumatoid arthritis - did not. Flow-mediated dilatation in both the groups of diseases was not different from controls. In rheumatoid arthritis patients, mean blood pressure was the main explanatory factor for augmentation index and pulse wave velocity; vessel diameter and high-density lipoprotein cholesterol - for flow-mediated dilatation. In women with systemic lupus erythematosus, pulse wave velocity was not related to any of the pending parameters; augmentation index was dependent on organ damage index, age, and mean blood pressure, and flow-mediated dilatation on vessel diameter, body mass index, and disease duration. CONCLUSIONS: The mean blood pressure was the major and the only one risk factor of arterial stiffening in rheumatoid arthritis, while the disease damage index played the most important role in the systemic lupus erythematosus group. The mean blood pressure in the systemic lupus erythematosus group was not as important as in the rheumatoid arthritis group, though may have a partial influence.

RESUMO

Systemic sclerosis (SSc) is characterized by thickening and fibrosis of skin and internal organs that is associated with vascular damage. SSc may lead to arterial dysfunction and premature aging of the arteries. However, its relationship with parameters of arterial wall dysfunction has not been fully explored. To determine if carotid-radial pulse wave velocity (PWV), aortic augmentation index (AIx) and endothelial function are altered in SSc patients, 17 consecutive patients with SSc and 34 age- and gender-matched controls were included in our study. PWV and AIx were assessed non-invasively by applanation tonometry. The endothelium-dependent flow-mediated dilatation (FMD) test in a brachial artery was performed by the ultrasound system. The blood investigations included serum lipid profile, glucose, and high-sensitivity CRP (hsCRP) measurements. As compared to controls, SSc patients had significantly higher medians of the AIx (p = 0.002) and the PWV (p = 0.04) and the median of the FMD was significantly lower (p = 0.001). Stepwise linear regression including comorbid factors showed that SSc was a significant independent predictor of all arterial wall parameters measures. SSc patients have increased AIx and PWV and lower FMD as compared to control subjects. The relationship between SSc and measures of arterial wall parameters still remains unclear. Though replication of the results presented here is required, we conclude that SSc has a great impact on large and conduit arteries damage.

RESUMO

OBJECTIVE: To investigate the relationship of arterial wall parameters (flow-mediated dilatation of the brachial artery, augmentation index, pulse wave velocity, stiffness index, carotid intima-media thickness) to conventional cardiovascular risk factors and cardiovascular risk assessed by SCORE system. MATERIAL AND METHODS: A total of 209 subjects aged 40-65 years without clinically overt cardiovascular disease were examined. Parameters of arterial stiffness were obtained by two methods: augmentation index and carotid-radial pulse wave velocity by applanation tonometry and stiffness index by the means of finger photoplethysmography. Flow-mediated dilatation of the brachial artery, reflecting endothelial function, and carotid intima-media thickness was determined using a high-resolution B-mode ultrasonography. RESULTS: Age and the presence of diabetes strongly influenced all parameters of the arterial wall (diabetes was not independent predictor when evaluating augmentation index). Mean arterial pressure and gender were independent predictors for arterial stiffness parameters--carotid-radial pulse wave velocity and augmentation index. Flow-mediated dilatation was strongly dependent on the diameter of the brachial artery, age, and body mass index. Using logistic regression, it was found that pulse wave velocity (P=0.014), intima-media thickness (P=0.004), and flow-mediated dilatation (P=0.020) were important parameters dividing subjects to the groups of increased (> or =5%) and low (<5%) cardiovascular risk assessed by SCORE system. The cutoff values for intima-media thickness and pulse wave velocity were 0.078 cm and 8.95 m/s, respectively. CONCLUSIONS: Arterial wall parameters are closely associated with conventional risk factors; they are influenced by age and the presence of diabetes. Arterial stiffness parameters are also influenced by mean arterial pressure; high-density lipoprotein cholesterol has influence on carotid intima-media thickness. Cutoff values for carotid intima-media thickness and carotid-radial pulse wave velocity could help to discriminate patients with increased cardiovascular risk.

RESUMO

Rheumatoid arthritis (RA) is accompanied by long lasting inflammation, which may lead to arterial dysfunction and premature aging of the arteries. The purpose of this clinical work was to determine the modification of carotid-radial pulse wave velocity (PWV) and aortic augmentation index (AIx) in young-aged RA patients and the influence of treatment with anti-TNF-alpha (infliximab) on these measures. We examined 68 RA patients (mean age 40.68 yrs) with moderate or high disease activity (DAS28 5.37 +/- 0.94) and 87 controls (mean age 38.10 yrs). PWV and AIx were assessed non-invasively by applanation tonometry. A blood test included serum lipid profile, and high-sensitivity CRP measurements. We found that in RA patients, AIx (p < 0.001) was significantly higher while PWV (p = 0.315) did not differ as compared to control. Multiple regression analysis revealed the presence of RA is an independent predictor for AIx (R2 = 0.718, adjusted R2 = 0.707; p < 0.001). Analysis (Mann-Whitney test) in 15 RA patients revealed lowering of PWV (p = 0.004) under infliximab therapy with no change in AIx (p = 0.573), suggesting the improvement of arterial wall function by anti-TNF-alpha therapy. We conclude that increased AIx is more prominent in RA patients as compared to the controls. PWV appears to be a less sensitive marker for the detection of enhanced development of arterial stiffness in relatively young-aged RA patients. However, PWV may serve as a good marker to discern effects of infliximab on artery elasticity.

RESUMO

Metabolic syndrome (MetS) is thought to increase cardiovascular risk. The aim of this study was to investigate whether the MetS and its components are associated with parameters of arterial stiffness, flow mediated dilatation (FMD) of the brachial artery, carotid intima-media thickness (IMT) and the presence of carotid plaques (CP) in middle-aged subjects. One-hundred eighty-six asymptomatic volunteers (40-65 years-old, 86 males and 100 females) without clinically overt cardiovascular disease were examined. MetS was defined according to the International Diabetes Federation consensus. The prevalence of MetS was 32.8% (61 subjects). Augmentation index (Alx) and carotid-radial pulse wave velocity (PWV) as parameters of arterial stiffness were assessed by applanation tonometry. FMD (as endothelial function) was determined using high resolution B-mode ultrasonography, as were IMT and CP. PWV was significantly elevated in the MetS group (9.20 +/- 1.08 vs. 8.70 +/- 1.02, p = 0.003). FMD was significantly lower in the MetS group (5.32 vs. 6.45%, p = 0.018). There was no statistically significant difference in AIx between subjects with and without MetS (23.97 +/- 8.08 vs. 23.30 +/- 9.75, p = 0.248, respectively). Multiple regression analysis has shown that the presence of MetS was a significant (p = 0.005) determinant of PWV but not FMD. IMT* was higher in the MetS group (0.08 [0.07-0.1] vs. 0.07 [0.06-0.08] p < 0.001). The presence of arterial hypertension was related to AIx (R2 = 0.444, adjusted R2 = 0.434, p = 0.001) and PWV (R2 = 0.161, adjusted R2 = 0.152, coefficient p = 0.001). Furthermore, mean arterial pressure (MAP) itself was an independent predictor of AIx (R2 = 0.571, adjusted R2 = 0.562, p < 0.001) and PWV (R2 = 0.281, adjusted R2 = 0.269, p < 0.001). Glycemia had an impact on IMT (R2 = 0.027, adjusted R2 = 0.022, p = 0.026). The MetS was a significant predictor of the presence of carotid plaques (OR = 0.341, 95 % CI [0.173 - 0.673], p = 0.002). Blood pressure is the most important determinant of structure and function of arteries.
