BACKGROUND: Pulmonary arterial hypertension (PAH) may lead to right heart failure and subsequently alter glomerular filtration rates (GFR). Chronic kidney disease (CKD, GFR <60 mL/min/1.73 m2) may also adversely affect PAH prognosis. This study aimed to assess how right heart hemodynamics was associated with reduced estimated GFR (eGFR) and the association of CKD with survival in PAH patients. METHODS: In a prospective PAH cohort (2003-2012), invasive hemodynamics and eGFR were collected at diagnosis (179 patients) and during follow-up (159 patients)...

Chronic obstructive pulmonary disease (COPD) is characterized by chronic expiratory airflow obstruction that is not fully reversible. COPD patients develop varying degrees of emphysema, small and large airway disease, and various co-morbidities. It has not been clear whether these co-morbidities share common underlying pathogenic processes with the pulmonary lesions. Early research into the pathogenesis of COPD focused on the contributions of injury to the extracellular matrix and pulmonary epithelial cells...

Group classification of pulmonary hypertension (PH) is based on pulmonary artery wedge pressure (PAWP) on right heart catheterization (RHC). How hemodynamics, particularly PAWP, change over time in systemic sclerosis (SSc)-PH patients is unknown. SSc-PH patients enrolled in the prospective observational PHAROS registry who had > 1 RHC (n = 120) were included in this analysis. Patients were considered to have a "PAWP class change" if they had a PAWP ≤ 15 mmHg on RHC-1 and then a PAWP > 15 on RHC-2 or had a PAWP > 15 on RHC-1 and then PAWP ≤ 15 on RHC-2...

Eicosanoids represent a diverse family of lipid mediators with fundamental roles in controlling physiology and disease. Within the eicosanoid super family are prostanoids, which are specifically derived from arachidonic acid by the enzyme cyclooxygenase (COX). COX has two isoforms; COX-1 and COX-2. COX-2 is the therapeutic target for the nonsteroidal anti-inflammatory drug (NSAID) class of pain medications. Of the prostanoids, prostacyclin, first discovered by Sir Professor John Vane in 1976, remains amongst the best studied and retains an impressive pedigree as one the bodies fundamental cardiovascular protective pathways...

BACKGROUND: The aim of this study was to build a clinical decision support system (CDSS) in diabetic retinopathy (DR), based on type 2 diabetes mellitus (DM) patients. METHOD: We built a CDSS from a sample of 2,323 patients, divided into a training set of 1,212 patients, and a testing set of 1,111 patients. The CDSS is based on a fuzzy random forest, which is a set of fuzzy decision trees. A fuzzy decision tree is a hierarchical data structure that classifies a patient into several classes to some level, depending on the values that the patient presents in the attributes related to the DR risk factors...

Disordered proliferation and angiogenesis of pulmonary artery endothelial cells is an important stage in the development of pulmonary arterial hypertension. Recent studies revealed that GDF11 (growth differentiation factor 11) induces endothelial cells proliferation and migration; however, whether GDF11 is directly involved in the pathogenesis of pulmonary arterial hypertension remains unknown. Here, we found that GDF11 was significantly upregulated and activated in 2 experimental pulmonary arterial hypertension models and cultured pulmonary artery endothelial cells...

BACKGROUND: Unilateral absence of the pulmonary artery (UAPA) is a rare congenital malformation often associated with other cardiac anomalies; however it may occur as an isolated lesion. Isolated absence of the right pulmonary artery is twice more frequent than that of the left pulmonary artery. Patients with isolated UAPA are usually asymptomatic at birth; thereafter they may develop a progression of symptoms such as exercise intolerance, dyspnea, chest pain, hemoptysis and recurrent pulmonary infections...

Hypertension and type 2 diabetes are common comorbidities. Hypertension is twice as frequent in patients with diabetes compared with those who do not have diabetes. Moreover, patients with hypertension often exhibit insulin resistance and are at greater risk of diabetes developing than are normotensive individuals. The major cause of morbidity and mortality in diabetes is cardiovascular disease, which is exacerbated by hypertension. Accordingly, diabetes and hypertension are closely interlinked because of similar risk factors, such as endothelial dysfunction, vascular inflammation, arterial remodelling, atherosclerosis, dyslipidemia, and obesity...

Peripheral artery disease (PAD) affects more than 200 million people worldwide. Hypertension has been related to increased risk of PAD. The treatment of elevated blood pressure (BP) in these patients is indicated to lower the cardiovascular risk with a BP goal of less than 130/80mmHg. Although there is no evidence that one class of antihypertensive medication or strategy is superior for BP lowering in PAD, the use of renin-angiotensin-system (RAS) inhibitors can be effective to reduce the cardiovascular risk...

The endocannabinoid system is overactivated in arterial, pulmonary and portal hypertension. In this paper, we present limited clinical data concerning the role of cannabinoids in human hypertension including polymorphism of endocannabinoid system components. We underline differences between the acute cannabinoid administration and their potential hypotensive effect after chronic application in experimental hypertension. We discuss pleiotropic effects of cannabinoids on the cardiovascular system mediated via numerous neuronal and non-neuronal mechanisms both in normo- and in hypertension...

Aging is a modern concept: human life expectancy has more than doubled in less than 150 years in Western countries. Longer lifespan, however, reveals age-related diseases, including cerebrovascular diseases. The vascular system is a prime target of aging: the "wear and tear" of large elastic arteries exposed to a life-long pulsatile pressure causes arterial stiffening by fragmentation of elastin fibers and replacement by stiffer collagen. This arterial stiffening increases in return the amplitude of the pulse pressure (PP), its wave penetrating deeper into the microcirculation of low resistance, high flow organs such as the brain...

Heart failure and related morbidity and mortality are increasing at an alarming rate, in large part, because of increases in aging, obesity, and diabetes mellitus. The clinical outcomes associated with heart failure are considerably worse for patients with diabetes mellitus than for those without diabetes mellitus. In people with diabetes mellitus, the presence of myocardial dysfunction in the absence of overt clinical coronary artery disease, valvular disease, and other conventional cardiovascular risk factors, such as hypertension and dyslipidemia, has led to the descriptive terminology, diabetic cardiomyopathy...
