Article Synopsis
  • Researchers aimed to explore the connection between vitamin D levels and cardiac natriuretic peptides in patients on chronic peritoneal dialysis.
  • They found that lower levels of vitamin D were significantly associated with higher levels of B-type natriuretic peptide (BNP), suggesting a potential link between vitamin D deficiency and heart function impairment.
  • The study concludes that vitamin D deficiency in patients with chronic renal failure may negatively affect cardiac function, as indicated by increased BNP levels.

Background: Cardiovascular risk factors including obesity, diabetes, hypertension, and dyslipidemia, are highly prevalent in the United Arab Emirates. In spite of significant awareness initiatives, little is known about the potential benefits of controlling these risk factors.

Aims: To assess the prevalence of preventable risk factors for coronary heart disease (CHD), and the likely benefits of controlling these risk factors.

Cardiovascular diseases (CVD) constitute a significant risk and may, in part, explain the high morbidity and mortality rates among haemodialysis (HD) patients. Several studies have implicated reduced insulin like growth factor (IGF-1) levels in the development of CVD. However, it is not clear whether IGF-1, and its relationship with other hormones such as leptin, insulin, and growth hormone (GH), as well as anthropometric variables may explain the high incidence of vascular complications in chronic kidney disease (CKD) patients.

Background: An association case-controlled study was carried out on a group of 151 United Arab Emirates nationals--62 normotensives with and without left ventricular hypertrophy (LVH) and 89 hypertensives, also with and without LVH--with a view to evaluating the value of an insertion/deletion (I/D) dimorphism located in the second intron of the human atrial natriuretic factor (ANF) gene in relation to left ventricular hypertrophy.

Subjects And Methods: Criteria used for LVH inclusion were: demonstration of Sokoloe and Lyon ECG criteria (sum of S wave in V(1), and tallest R wave in lead V5 or V6 > or =35 mm) and echocardiography findings (interventricular septum > or =1.2 cm; posterior LV wall > or =1.

Background: Hypertension, notably untreated or uncontrolled, is a major risk factor for cardiovascular diseases (CVD) morbidity and mortality. In countries in transition, little is known about the epidemiology of hypertension, and its biochemical correlates. This study was carried out in Al Ain, United Arab Emirates, to characterize self-reported (SR) normotensives and hypertensives in terms of actual hypertension status, demographic variables, CVD risk factors, treatment, and sequalae.

The number of patients requiring long-term haemodialysis is increasing throughout the world. Cardiovascular disease is much more common in these patients than in the general population and accounts for the majority of deaths. New approaches to management are clearly needed to reduce this excessive cardiovascular burden.

Objective: In end-stage renal failure, dyslipoproteinemia is linked to risk of cardiovascular disease. Increased concentrations of triacylglycerol-rich, very low density lipoproteins (VLDL) and decreased concentrations of high density lipoproteins (HDL) are usual, whilst total cholesterol and low density lipoprotein (LDL) concentrations are not increased. Non-esterified fatty acids (NEFA) are not transported by lipoproteins, but increased concentrations may also be associated with cardiovascular disease risk.

In this study the effect of diabetes mellitus on atrial natriuretic peptide (ANP) receptors in streptozotocin- (STZ-) induced diabetic rat kidneys was studied. Moreover, plasma ANP concentration was evaluated in diabetic and control rats by using radioimmunoassay. In addition, the expression of ANP in the kidneys of control and diabetic rats was evaluated by immunohistochemistry.
