Platelet membrane fluidity, platelet membrane lipid pattern and platelet cytosolic Ca2+ content in subjects with vascular atherosclerotic disease

1994

In a group of subjects with vascular atherosclerotic disease (V AD) we examined the platelet membrane fluidity (obtained marking intact resting platelets with TMA-DPH), the platelet membrane cholesteroVphospholipid ratio (CIPL using column chromatography), the platelet membrane individual phospholipids (employing the thin layer chromatography) and the platelet cytosolic Ca2+ content (evaluated marking intact resting platelets with Fura 2-AM). From the obtained data, it is evident that platelet membrane fluidity differentiates normals from V AD subjects. Platelet membrane lipid pattern (CIPL and individual phospholipids) and cytosolic Ca2+ content do not discriminate normals from V AD subjec…

Practical solutions to the challenges of uncontrolled hypertension: a white paper.

2008

This white paper is an urgent call to action from aninternational group of physicians. The continued failure tocontrolhypertensiontakesanunacceptabletollon patients,families and society and it must be addressed. Any patientwith blood pressure of 140/90 mmHg or greater can becharacterizedasa ‘challengingpatient’,is atsignificant risk,and requires persistent optimization of therapy until targetblood pressure is achieved. Six key challenges in reachingthis goal blood pressure are described: (1) inadequateprimary prevention; (2) faulty awareness of risk; (3) lack ofsimplicity; (4) therapeutic inertia; (5) insufficient patientempowerment; and (6) unsupportive healthcare systems.This white paper id…

P674Metabolic deregulation in myocardial infarction is mediated by PGC-1 alpha pathway

2014

Purpose: In the context of myocardial infarction (MI) the availability of metabolites is clearly restricted, therefore a fuel metabolic shifts takes place. Previous studies have indicated that peroxisome proliferator activated receptor co-activator alpha (PGC-1α) pathway is a crucial regulator of cardiac metabolism in response to cardiac stress. Here we address the role of PGC-1α in regulating metabolic changes of MI. Methods: We studied a group of 12 common swine in which anterior MI was induced by means of angioplasty balloon inflation. A series of 6 swine were sacrificed at 48h post-infarction (acute infarction group) and another series of 6 swine were sacrificed at 3 weeks (chronic infa…

AORTIC STIFFNESS IS INCREASED IN NORMOTENSIVE PATIENTS WITH SYSTEMIC LUPUS ERYTHEMATOSUS

2018

INTRODUCTION: Patients with systemic lupus erythematosus (SLE) have a 4- to 10-fold increased risk of developing cardiovascular (CV) events compared with the general population. The enhanced CV risk conferred by SLE may in part be mediated through preclinical CV damage. Large artery stiffness is usually assessed by measuring aortic pulse wave velocity (aPWV), a marker of early vascular aging (EVA) and an independent predictor of adverse CV prognosis. Several studies examined aortic stiffness in SLE with inconsistent results. AIM: To evaluate aPWV and the prevalence of EVA in a group of normotensive patients with SLE and to compare these values with those obtained in age- and gender- matched…

Objective: High-intensity interval training (HIIT) can be extremely demanding and can consequently produce high blood lactate levels. Previous studies have shown that lactate is a potent metabolic stimulus, which is important for adaptation. Active recovery (ACT) after intensive exercise, however, enhances blood lactate removal in comparison with passive recovery (PAS) and, consequently, may attenuate endurance performance improvements. Therefore, the aim of this study was to examine the influence of regular ACT on training adaptations during a HIIT mesocycle. Methods: Twenty-six well-trained male intermittent sport athletes (age: 23.5 ± 2.5 years; O2max: 55.36 ± 3.69 ml min kg-1) participa…

Exercise causes blood glutathione oxidation in chronic obstructive pulmonary disease: prevention by O2 therapy

1996

Viña, José, Emilio Servera, Miguel Asensi, Juan Sastre, Federico V. Pallardó, José A. Ferrero, JoséGarcı́a-de-la-Asunción, Vicente Antón, and Julio Marı́n. Exercise causes blood glutathione oxidation in chronic obstructive pulmonary disease: prevention by O2therapy. J. Appl. Physiol. 81(5): 2199–2202, 1996.—The aim of the present study was to determine whether glutathione oxidation occurs in chronic obstructive pulmonary disease (COPD) patients who perform exercise and whether this could be prevented. Blood glutathione red-ox ratio [oxidized-to-reduced glutathione (GSSG/GSH)] was significantly increased when patients performed exercise for a short period of time until exhaustion. Their res…

2021 European Society of Hypertension practice guidelines for office and out-of-office blood pressure measurement.

2021

High blood pressure (BP) is the leading modifiable risk factor for morbidity and mortality worldwide. The basis for diagnosing and managing hypertension is the measurement of BP, which is routinely used to initiate or rule out costly investigations and long-term therapeutic interventions. Inadequate measurement methodology or use of inaccurate BP measuring devices can lead to overdiagnosis and unnecessary treatment, or underdiagnosis and exposure to preventable cardiovascular disease (CVD).
