Acute life-threatening situations are particularly critical when superimposed on chronic diseases. The objective of this study was the assessment of heart rate (HR) dynamics during episodes of acute anoxia superimposed on a rat model of chronic pulmonary hypertension. In 10 adult Wistar rats, five weeks after pulmonary hypertension induction with Monocrotaline, we analysed eight 1-min HR segmen...

BACKGROUND Sleep apnea syndrome (SAS) is an independent risk factor for hypertension which is a major risk factor for acute aortic dissection. The purposes of this study were to assess the prevalence of SAS in patients with acute aortic dissection, delineate the characteristics of patients who have acute aortic dissection with SAS. METHODS Of 95 consecutive patients with acute aortic dissecti...

BACKGROUND Hypertension is a powerful risk factor for cardiovascular disease and frequently occurs in conjunction with obesity. Accumulative evidence suggests a link between inflammation and hypertension. The aim of study was to evaluate whether blood pressure, obesity and smoking may influence acute-phase response. MATERIAL/METHODS Ninety-two patients with essential hypertension and 75 healt...

Acute renal failure (ARF) is defined as a sudden and continuous decrease of glomerular function associated with azotemia, and may be followed by decreased urinary output. There is a high incidence of ARF in ICU patients with a high mortality rate. Many factors can promote ARF development or influence its outcome. This study was done to assess the incidence, risk factors, outcome and treatme...

PURPOSE The aim of this study was to assess the clinical characteristics of hypertensive encephalopathy according to the underlying etiologies in children. METHODS We retrospectively evaluated 33 pediatric patients who were diagnosed as having hypertensive encephalopathy in Chonbuk National University Children's Hospital. Among the patients, 18 were excluded because of incomplete data or beca...

OBJECTIVE Circulatory failure due to acute arterial hypertension in the neonatal period is rare. This study was undertaken to assess the clinical and echocardiographic manifestations of circulatory failure resulting from acute neonatal hypertensive crisis. METHODS Neonatal and cardiology databases from 2007 to 2010 were reviewed. An established diagnosis of circulatory failure due to neonatal...

 Background: The role of uric acid as a risk factor for vascular disease and acute stroke is controversial and there is little information about it. In this study, we determined serum uric acid levels in patients with acute stroke and assessed its relationship with cerebrovascular risk factors. Methods: In this cross sectional study, we assessed patients with acute stroke who were admitted in F...

BACKGROUND Malignant hypertension is a condition characterized by severe hypertension and multi-organ ischemic complications. Albeit mortality and renal survival have improved with antihypertensive therapy, progression to end-stage renal disease remains a significant cause of morbidity and mortality. The underlying cause of malignant hypertension, which can be primary or secondary hypertension,...

To assess the effects of genetic predisposition of essential hypertension on early renal function in recent insulin-dependent diabetics, we studied inulin, para-aminohippuric, sodium, and lithium clearances in 69 unselected diabetics with (n = 20) and without (n = 49) a family history of essential hypertension. Despite similar metabolic control, glomerular filtration rate and mean arterial pres...

hypertension is a common complication of kidney transplantation with the prevalence of 80%. studies in adults have shown a high prevalence of hypertension (htn) in the first three months of transplantation while this rate is reduced to 50- 60% at the end of the first year. htn remains as a major risk factor for cardiovascular diseases, lower graft survival rates and poor function of transplante...
