Obesity, elevated levels of fasting plasma glucose and type 2 diabetes are associated with aortic stiffness.

OBJECTIVES: Obesity and metabolic syndrome (MetS) are associated with structural and functional vascular abnormalities. MetS and its components may increase arterial stiffness and the risk of cardiovascular events. However, the relationship of MetS and its components, including obesity, with arterial stiffness is still not fully understood. SUBJECTS AND METHODS: In a group of 116 patients undergoing treatment for hypertension, we searched for the relationships between parameters of MetS and aortic stiffness expressed by pulse wave velocity (PWVAo). PWVAo was measured using an arteriograph working on the oscillometric principle, and pulse wave analysis (PWA) for noninvasive assessment of the parameters of central hemodynamics. RESULTS: From the cluster of parameters of MetS we found a significant association between body mass index (BMI) and aortic stiffness, and between fasting plasma glucose/type 2 diabetes (FPG/T2DM) and aortic stiffness. We did not find significant relationships between other components of MetS (HDL cholesterol and triglycerides) and aortic stiffness, based on the influence of hypolipidemic therapy. Arterial stiffness increased with age and was higher in females. CONCLUSION: Arterial stiffness was associated with age, sex, and MetS components (BMI and FPG/T2DM). Surprisingly, the parameters of dyslipidemia do not influence stiffness parameters, which can be explained by hypolipidemic therapy. The influence of hypolipidemic therapy should therefore be borne in mind when evaluating arterial tree function (Tab. 15, Ref. 62).

Secondary prevention after acute coronary syndrome.

Patients suffering acute coronary syndrome have a very high risk for a repeated syndrome. After stabilization of acute coronary syndrome and discharge of a patient it is important to educate the patient how to prevent it in the future (dietary and life style changes), but treatment of all cardiovascular risk factors/diseases, as hypertension, dyslipidemia, diabetes but stabilization of all cardiovascular diseases is also important. Important is also antithrombotic treatment (mostly double antiplatelet treatment when percutaneous coronary intervention was used with a coronary stents), RAAS blockers, betablockers and statins (strong as atorvastatin and rosuvastatin in the highest possible dose). There are also new risk factors, and vascular inflammation belongs here. We have nowadays also some successful clinical studies how to block inflammation and how to use this treatment. A good secondary cardiovascular prevention is able to improve enourmously prognosis of these patients.

Overview of the Pathogenesis, Genetic, and Non-Invasive Clinical, Biochemical, and Scoring Methods in the Assessment of NAFLD.

Nonalcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide. It represents a range of disorders, including simple steatosis, nonalcoholic steatohepatitis (NASH), and liver cirrhosis, and its prevalence continues to rise. In some cases, hepatocellular carcinoma (HCC) may develop. The develop;ment of non-invasive diagnostic and screening tools is needed, in order to reduce the frequency of liver biopsies. The most promising methods are those able to exclude advanced fibrosis and quantify steatosis. In this study, new perspective markers for inflammation, oxidative stress, apoptosis, and fibrogenesis; emerging scoring models for detecting hepatic steatosis and fibrosis; and new genetic, epigenetic, and multiomic studies are discussed. As isolated biochemical parameters are not specific or sensitive enough to predict the presence of NASH and fibrosis, there is a tendency to use various markers and combine them into mathematical algorithms. Several predictive models and scoring systems have been developed. Current data suggests that panels of markers (NAFLD fibrosis score, Fib-4 score, BARD score, and others) are useful diagnostic modalities to minimize the number of liver biopsies. The review unveils pathophysiological aspects related to new trends in current non-invasive biochemical, genetic, and scoring methods, and provides insight into their diagnostic accuracies and suitability in clinical practice.

Central Systolic Hypertension in Patients with Well-Controlled Hypertension.

Background. Central systolic blood pressure (CSBP) has prognostic significance and simplified devices for its estimation have been introduced recently. The aim of this study was to assess the achievement of the target CSBP in treated hypertensive patients. Subjects and Methods. One hundred patients with well-controlled hypertension were analysed. For CSBP estimation, we used the Arteriograph (TensioMed Ltd.), which uses one cuff for all measurements, the "single-point measurement" approach. Results. We found that 62% of patients had CSBP ≥ 130 mmHg, the suggested cut-off value for hypertension. When sex-specific classification was employed (CSBP ≥ 137 mmHg for female and CSBP ≥ 133 mmHg for male), only 13% of patients (mainly women) remained in the hypertensive range. We also found that 55% of patients had a CSBP higher than brachial pressure. Multiple analyses showed that CSBP was significantly associated with sex, height, and return time. Conclusions. A high proportion of treated hypertensive patients had CSBP levels that exceeded their brachial BP. CSBP positively correlated with lower height and shorter return time of the reflected pressure wave and was significantly higher in females compared to males. These findings suggest that, for CSBP classification, it is important to take height and sex-specific differences into account.

[Preclinical cardiovascular diseases and aortic stiffness]. / Predklinické kardiovaskulárne ochorenia a tuhost aorty.

AIM: To compare aortic stiffness (represented by aortic pulse wave velocity - PWVao) as a marker of cardiovascular risk with cardiovascular risk estimated by standard scoring systems in treated hypertensive patients. PATIENTS AND METHODS: In a group of 41 hypertensive patients without clinical manifestation of cardiovascular disease (18 men/23 women, mean age 59 years) we investigated the presence of risk factors and preclinical cardiovascular diseases. To estimate cardiovascular risk we have used SCORE-HDL model and categorical risk stratification recommended by ESC/ESH. Linear regression was used for evaluation of relation between risk estimation scores and PWVao values. RESULTS: We have found out statistically significant relationship between PWVao and cardiovascular risk assessment systems in our group of patients. The correlation between PWVao and ESC/ESH risk stratification (r = 0.414, P < 0.01) was the most relevant, the correlation between PWVao and SCORE-HDL values was also significant (r = 0.315; P < 0.05). CONCLUSIONS: Increased aortic stiffness as one of the preclinical cardiovascular diseases can be an integrative marker of cardiovascular risk in patients with arterial hypertension.
