BACKGROUND The relationship of aortic valve dysfunction and ascending aortic aneurysm is unclear in adults with bicuspid aortic valve disease. METHODS We retrospectively studied 134 consecutive out-patients (98 men, 36 women aged 43 ± 18 years) with bicuspid aortic valve disease. To investigate the relationship of ascending aortic aneurysm and aortic valve dysfunction we exclusively considere...
The patient was a 19 year-old woman with the diagnosis of resistant hypertension, although she was under treatment of three classes of anti-hypertensive drugs (beta blocker, angiotensin receptor blocker, diuretic) for more than one year. In physical examination there was only a significant difference between the systolic blood pressure of upper and lower extremities (200 vs. 120 mmHg), without ...
Artemisia species, growing in almost all the northern hemisphere, is used in folk medicine of some countries as a remedy for hypertension. Since some cardiovascular disorders including hypertension are accompanied with altered responsiveness of vascular alpha-adrenergic receptors, the effect of aqueous Artemisia annua extract (100 and 200 mg kg-1) on a1-adrenoceptor agonist-induced contraction ...
Angiotensin-converting enzyme (ACE) inhibitors appear to correct many of the abnormalities associated with the vascular dysfunction found in diabetic patients. In this respect, quinapril is a unique ACE inhibitor with multiple protective effects. The present study was carried out to investigate the effect of intraperitoneal administration of quinapril on the aortic reactivity of streptozotocin ...
Objective(s): Atherosclerosis is an important risk factor for coronary heart disease. Neuropeptide Y (NPY) and its receptors, located in peripheral tissue such as white adipose tissue, have been linked to obesity and fat storage. The role of NPY in atherosclerosis has not yet been fully studied, so this study was conducted to further investigate the effect of BIIE 0246, an NPY receptor antagoni...
Cardiovascular disorders continue to constitute major causes of morbidity and mortality in diabetic patients. In this study, the effect of chronic administration of sesame (Sesamum indicum L) seed feeding was studied on aortic reactivity of streptozotocin (STZ)-diabetic rats. Male diabetic rats received sesame seed-mixed food at weight ratios of 3% and 6% for 7 weeks, one week after diabetes in...
Introduction:Severe abdominal aortic constriction above the renal arteries induces arterial hypertension above the stenotic site that is the cause of cardiac hypertrophy. Previous studies have shown that high blood pressure induces myocardial oxidative stress with conflicting results. In the present study, we assessed the effects of acute hypertension on the myocardial oxidative stress an...
Aims: Type 2 diabetes is a rising problem and a significant risk factor for small and large vessel disease. The present study aims to investigate the effect of a 6-week aerobic exercise program on High-mobility Group Box 1 (HMGB1) gene expression in aortic tissue of diabetic rats. Methods & Materials: In this experimental study, 40 male rats aged 8 weeks were randomly selected. Once familiariz...
Dear Editor,Abdominal aortic aneurysm is often asymptomatic, less recognized, and causes considerable mortality and morbidity, if missed. The incidence varies from country to country and the occurrence is influenced by modifiable (smoking, coronary heart disease, hypertension, dyslipidemia, and prolonged steroid therapy) and non-modifiable risk factors (increasing age, male gender, and positive...
ABSTRACT: Acute rheumatic fever and rheumatic heart disease are the common health problems of developing countries.Prevention and Control of Rheumatic heart disease is an important task of cardiovascular health program under World Health organisation. During 3 years 422,000 School children in four areas of Guilan province were screened (371400 urban and 50600 rural area children ). 166 cases ...
