BACKGROUND: Familial hypercholesterolemia (FH) is a genetic disorder that manifests as impaired low-density lipoprotein cholesterol (LDL-C) metabolism, resulting in lifelong exposure to high cholesterol levels and increased risk of cardiovascular disease (CVD). There is heterogeneity in cardiovascular risk for FH patients, so risk stratification is of utmost importance. The aim of this study was to evaluate the impact of increases in LDL-C and the impact of other CVD risk factors on vascular markers in the FH patient population. METHODS: A total of 428 patients were included in this study and divided into two groups according to age: ≤40 years in the first group and ≥41 years in the second group. Vascular markers of atherosclerosis included the common carotid artery (CCA) intima–media thickness (IMT), pulse wave velocity (PWV), flow-mediated dilation (FMD), ankle–brachial index (ABI), and cardio-vascular index (CAVI). The influence of traditional CVD risk factors on atherosclerotic changes in vascular markers was analyzed. RESULTS: A statistically significant difference in IMT was detected between the same sex and different age groups (p < 0.001), whereas no significant difference was detected between the sexes within each age group. In the ≤40-year-old group, the mean IMT among males was 612.5 μm (±88.2) and that among females was 580.6 μm (±77.7) (p > 0.05); in the ≥41-year-old group, the mean IMT was 697.4 μm (±138.4) for males and 700.3 μm (±114.4) for females (p > 0.05). Higher LDL-C was associated with greater IMT (r = 0.405; p = 0.009) in the younger age group (≤40 years); however, in the older age group (≥41 years), this correlation was not evident (r = −0.07; p = 0.596). Carotid plaque formation was more common among males (OR = 2.2; 95% CI: 1.2–4.0) and hypertensive patients (OR = 2.7; 95% CI: 1.6–4.7). Age was a mildly significant risk factor for increased ABI (β = 0.13, p < 0.05). FMD was found to be impaired for all patients, and no risk factors were shown to have further influence. Age was a significant risk factor for increased arterial stiffness, as measured by both the CAVI and PWV. Conclusions: Although vascular markers of atherosclerosis may provide a unique and valuable way to evaluate cardiovascular risk, the results of this study show that only increased IM thickness could be beneficial for risk stratification in young FH patients, whereas other vascular markers of atherosclerosis would be excessive, as they do not provide merit in risk evaluation in this population.

Background: Hypertension is one of the most common cardiovascular risk factors worldwide. Additionally, epidemiological studies show a worryingly high prevalence of treatment-resistant hypertension. Especially concerning is the frequent co-occurrence of other cardiovascular risk factors, including dyslipidaemia, smoking, and diabetes mellitus. Objectives: The aim of this study is to investigate the prevalence of arterial hypertension and other cardiovascular risk factors in patients aged 50–54 years. Methods: A retrospective study was conducted on patients participating in the Lithuanian High Cardiovascular Risk Primary Prevention Programme. Data were collected from self-report questionnaires, laboratory tests, and clinical assessment. Hypertension was confirmed if systolic blood pressure was ≥140 mmHg and/or diastolic blood pressure was ≥90 mmHg or the patient had been previously diagnosed. Results: In total, 49155 patients—32018 (62.4%) women and 17137 (37.6%) men—were enrolled in this study. A total of 24549 (49.9%) patients were diagnosed with arterial hypertension. The prevalence of non-resistant primary hypertension was 45.9%, while the prevalence of resistant primary hypertension was 4.1%. The prevalence of dyslipidaemia was 92.79% in the non-resistant primary arterial hypertension group and was 94.59% in the resistant primary arterial hypertension group. The prevalence of smoking was higher in the non-resistant primary arterial hypertension group compared to patients with resistant hypertension (22.43% and 17.09%, respectively). A total of 23.06% of patients with resistant primary arterial hypertension had diabetes mellitus. Conclusions: The prevalence of primary arterial hypertension in middle-aged Lithuanians was high, reaching almost 50% in both sexes. Patients tended to have many cardiovascular risk factors simultaneously, with dyslipidaemia being the most common (prevalence > 90%).

Background and Objectives: Atherosclerotic cardiovascular disease is one of the most common causes of death and disability around the world. Hypercholesterolemia is an established and widely prevalent risk factor; however, the prevalence of severe hypercholesterolemia (which is characteristic for familial hypercholesterolemia) has been studied far less. The aim of this study was to determine the prevalence of severe hypercholesterolemia among patients with acute coronary syndrome. Materials and Methods: A retrospective study of patients hospitalised at Vilnius University Hospital Santaros Klinikos due to acute coronary syndrome was performed. Data were attained from an electronic medical history database. Data such as sex, age, cardiovascular risk factors (hypertension, diabetes) and low-density cholesterol results were collected. Severe hypercholesterolemia was defined as low-density lipoprotein cholesterol levels ≥ 4.9 mmol/L. Results: A total of 34,669 patients were included in this study (12,115 females (34.9%) and 22554 (65.1%) males, p < 0.001). The median age of the entire study population was 67 years. A total of 3434 patients (9.9%) had severe hypercholesterolemia, 371 (1.1%) patients met the criteria for phenotypically probable familial hypercholesterolemia, and 36 (0.1%) patients presented with phenotypically definite familial hypercholesterolemia. The most common concomitant risk factor in this study was arterial hypertension, which was found in 48% of patients. Conclusions: Based on the results of this study, severe hypercholesterolemia is prevalent among patients with acute coronary syndrome, with as many as 9.9% of patients presenting with severe hypercholesterolemia at the time of hospitalisation. The definite familial hypercholesterolemia phenotype is scarcer, with prevalence reaching 0.1% of patients with acute coronary syndrome.
