Markers of arterial stiffness are useful tools to identify early atherosclerosis and adverse clinical outcomes in young adults and individuals with a modest risk factor profile. Assessing arterial stiffness may facilitate cardiovascular risk stratification beyond traditional risk scores.

We investigated the association of endothelial glycocalyx damage with arterial stiffness, impairment of coronary microcirculatory function, and LV myocardial deformation in 320 untreated hypertensives and 160 controls. We measured perfused boundary region (PBR) of the sublingual microvessels, a marker inversely related with glycocalyx thickness, coronary flow reserve (CFR), and Global Longitudinal strain (GLS) by echocardiography, pulse wave velocity (PWV), and central systolic blood pressure (cSBP). Hypertensives had higher PBR, PWV cSBP, and lower CFR and GLS than controls (P < .05). In hypertensives, increased PBR was associated with increased cSBP, PWV, and decreased CFR and GLS after adjustment for age, sex, BMI, smoking LV mass, heart rate, hyperlipidemia, and office SBP (P < .05). PBR had an additive value to PWV, CFR, and office SBP for the prediction of abnormal GLS (x 2 = 2.4-3.8, P for change = .03). Endothelial glycocalyx is impaired in untreated hypertensives and is related to arterial stiffness, coronary, and myocardial dysfunction. | 673IKONOMIDIS et al.reserve (CFR), a marker of coronary microcirculatory function, is related to arterial stiffness and is impaired in hypertensive heart disease. 22 The effect of endothelial glycocalyx damage on arterial wall properties, coronary flow reserve, and LV myocardial deformation has not been clarified.We hypothesized that endothelial glycocalyx is impaired in newly diagnosed untreated hypertensives, leading to impaired arterial elasticity, coronary flow reserve, and consequently, abnormal myocardial deformation. Therefore, we investigated the association of endothelial glycocalyx damage with pulse wave velocity, coronary flow reserve, and LV myocardial deformation in untreated hypertensives. | MATERIAL S AND ME THODS | Study populationOut of 348 consecutive patients with new onset essential hypertension who attended our outpatient hypertension clinic, 320 patients (mean age: 51 ± 11 years, 67% males) with normal ejection fraction (>60%) had adequate 2-dimensional echocardiography images for the analysis of speckle parameters (feasibility of the method 92%). The diagnosis of essential hypertension was defined as One-hundred and sixty normotensive individuals (age:48 ± 13 years, 66% males) who visited our outpatient clinic for a routine check-up were selected using a ratio of 1 control to 2 hypertensive patients as controls.Exclusion criteria were history of diabetes, familiar hyperlipidemia, coronary artery disease (CAD), cardiomyopathy, and chronic pulmonary disease. All patients and controls had no history of CAD, normal resting electrocardiogram, and underwent a non-invasive test (thallium scintigraphy after a treadmill exercise test or dobutamine stress echocardiography) to exclude myocardial ischemia. None of the female patients were on hormone replacement treatment. None of the patients or controls were on any kind of medication, including statins. All patients and controls had a glomerular filtration rate (GFR) > 60 mL/min/1.732 (MDRD formula) at enr...

The association between chronic inflammatory diseases (CIDs) and increased cardiovascular (CV) risk is well documented and can be a most threatening complication in these patients. However, the pathogenetic mechanisms underlying increased CV risk remain elusive, especially in their cellular and biochemical pathways. Using animal models to understand mechanisms underlying cardiac involvement are limited. Additionally, treatments may influence cardiovascular events through different outcomes. Some drugs used to treat CIDs can negatively affect cardiac function by a direct toxicity, whereas others may protect the myocardium. In the present article, we focus on the cardiac manifestations and risk factors, the pathogenetic mechanisms, and the effect of treatments on myocardial function and cardioprotection for five common worldwide CIDs (rheumatoid arthritis, systemic lupus erythematosus, systemic sclerosis, psoriasis and inflammatory bowel disease). We also give recommendations in order to evaluate common targets between CID and CV disease (CVD) and to design therapies to alleviate CID-related CVD.
