Increased Platelet Sensitivity toward Platelet Inhibitors during Physical Exercise in Patients with Coronary Artery Disease

1999

Generalized atherosclerosis and coronary artery disease (CAD) are associated with endothelial dysfunction and during acute myocardial ischemia platelet activation has been reported. Activated platelets exert activated fibrinogen receptors (GP IIb/IIIa) and express CD 62p being regarded as reliable marker for platelet activation. Patients with angiographically proven CAD performed a bicycle exercise test until the onset of angina or ST-segment depression. We studied the ischemia-induced alterations in fibrinogen binding to activated platelet GP IIb/IIIa receptors and CD 62p expression. Therefore, the basal fibrinogen binding to GP IIb/IIIa and CD 62p expression and the thrombin-concentration…

Markers of Inflammation and Infection Influence the Outcome of Patients With Baseline Asymptomatic Carotid Lesions

2005

Background and Purpose— It is still in debate whether the evaluation of markers of infection and inflammation may be of importance for cerebrovascular and cardiovascular prevention, and we aimed to investigate this field in a prospective 5-year clinical follow-up study in patients with early stages of atherosclerosis. Methods— We studied 668 subjects divided in 3 groups according to the results of carotid ultrasound examination: (1) normal subjects, if intima-media thickness (IMT) was <0.9 mm; (2) with IMT, if IMT was between 0.9 and 1.5 mm; and (3) with asymptomatic carotid plaque, if IMT was >1.5 mm. Traditional cardiovascular risk factors were investigated, and laboratory analysis…

Elevated levels of lipoprotein (a) in patients suffering from myocardial infarction with carotid atherosclerotic lesions.

1999

The aim of the present study was to evaluate metabolic, coagulation and fibrinolytic parameters in 45 patients [31 men, 14 women, aged 56.5 +/- 3.5 years (mean +/- SD)] who had suffered myocardial infarction more than 6 months earlier, with or without carotid atherosclerotic lesions. After the extracranial carotid arteries had been evaluated using a B-mode Duplex scanning system, patients were subdivided into two groups: group 1 (n = 20) with carotid plaques or measurable intima-media thickness; and group 2 (n = 25) without carotid plaques or measurable intima-media thickness. Twenty-two age- and sex-matched subjects were recruited as controls (group 3). Groups 1 and 2 displayed significant…

Inflammation, atherosclerotic burden and cardiovascular prognosis.

2006

The aim of this study was to evaluate the impact of various inflammatory markers on atherosclerotic burden and cardiovascular prognosis.In a prospective study 720 patients preceding coronary angiography were enrolled. In all patients carotid and leg arteries were examined using sonographic methods and C-reactive protein, fibrinogen, interleukin-18 (IL-18) and interleukin-6 have been determined. Patients were compared with regard to atherosclerotic burden: no clinically significant stenosis (N=57, 7.9%), coronary artery disease only (N=362, 50.3%), coronary artery disease with peripheral atherosclerosis (=multi-vascular atherosclerosis, N=301, 41.8%).Follow-up data after a median of 6.5 year…

Prediction of cardio- and cerebro-vascular events in patients with subclinical carotid atherosclerosis and low HDL-cholesterol.

2007

Low HDL-cholesterol concentrations are associated with increased cardiovascular risk and recent evidences suggest that HDL may aggravate the atherosclerotic process promoting inflammation: HDL are anti-inflammatory in the absence of inflammation but can become proinflammatory in the presence of atherosclerosis. Yet, no data is available on the cardiovascular outcome in subjects with low HDL-cholesterol and early stages of atherosclerosis. Therefore, we included in a prospective 5-year follow-up study 150 subjects with low HDL-cholesterol concentrations and subclinical carotid atherosclerosis, as assessed by carotid colour doppler, evaluating at baseline all the established traditional cardi…

An assessment of the hemorheological profile in patients with subclinical carotid atherosclerosis divided in relation to the number of cardiovascular…

2021

We present a cohort of 100 subjects [43 men and 57 women; median age 66.00(25)] who were tested using carotid ultrasound to identify subclinical carotid atherosclerosis (SCA). We have evaluated the behaviour of whole blood viscosity (WBV) at high (450 s–1) and low (0.51 s–1) shear rates, plasma viscosity (450–1), hematocrit and mean erythrocyte aggregation. When compared to normal control subjects, using the Mann-Whitney test, we observed in SCA patients a significant increase in WBV only. The results were substantial after having divided the SCA subjects according to the cardiovascular risk factors (CRFs) and the degree of insulin resistance; the research was performed using two surrogate …

Association of elevated fibrinogen and C-reactive protein levels with carotid lesions in patients with newly diagnosed hypertension or type II diabet…

2006

BACKGROUND: Inflammation may be important for accelerated progression of atherosclerosis in patients with hypertension or diabetes, but few studies included subjects with early stages of atherosclerosis such as those with asymptomatic carotid lesions. METHODS: We studied 100 patients with newly diagnosed hypertension and another 100 patients with newly diagnosed type II diabetes to evaluate in such groups the association of two markers of inflammation, fibrinogen and C-reactive protein (CRP), with carotid atherosclerosis, beyond traditional cardiovascular risk factors (e.g., older age, male gender, obesity, smoking, family history of CAD, dyslipidemia). RESULTS: We found positive correlatio…

Markers of inflammation are strong predictors of subclinical and clinical atherosclerosis in women with hypertension

2008

Cardiovascular diseases in women still rises and remains their leading cause of death in most developed countries; yet we have less sex-specific data in women than in men as a result of lower enrollment in clinical trials and low rates of sex-specific reporting. The aim of our study was to evaluate in hypertensive postmenopausal women the potential predictive role of markers of inflammation, for example, fibrinogen and C-reactive protein (CRP), on subclinical and clinical atherosclerosis, beyond that of the other established cardiovascular risk factors. We studied 127 asymptomatic hypertensive postmenopausal women with different degrees of carotid intima–media thickness, as examined by the …
