Nitrates have been shown to decrease portal pressure in cirrhotic patients with portal hypertension and this has been attributed to decreased portal venous resistance. We studied the effect and mechanism of action of oral administration of isosorbide-5-mononitrate (Is-5-Mn) (20 mg), which, unlike the dinitrate, does not require hepatic biotransformation to a vasoactive metabolite on portal and ...

Little is known about environmental determinants of type 2 diabetes. The authors hypothesized that insulin resistance is positively related to distance to a wealthy area and to local neighborhood poverty. Data were derived from The Multi-Ethnic Study of Atherosclerosis, a study of adults aged 45-84 years in six US locales, and the 2000 US Census. The homeostasis model assessment (HOMA) index wa...

Previous reports have demonstrated that haemodynamic responses to various autonomic stresses such as head-up tilt, Valsalva’s manoeuvre, face immersion, cold pressor, and static exercise are altered with increasing age and cardiac disease. In the present investigation, we compared the responses of 20 to 27 year old and 50 to 59 year old healthy men and 50 to 59 year old ambulatory coronary hear...

Background and purpose: Abortion is considered recurrent when it spontaneously occurs at least three times. Recent studies suggest a correlation between uterine artery resistance and recurrent miscarriage (RM). There are few studies on the ovarian arteries. Therefore, this study evaluated the resistance of uterine and ovarian arteries in unexplained recurrent miscarriage and normal fertile w...

OBJECTIVE Hepatitis C virus (HCV) infection is associated with higher insulin levels and insulin resistance. We evaluated factors associated with insulin resistance in a cohort of HIV/HCV-coinfected patients and determined the effect of insulin resistance on the development of hepatic fibrosis. METHODS Data were analysed from 158 nondiabetic participants in a prospective Canadian cohort of HI...

OBJECTIVE Insulin resistance is associated with increased triglyceride levels, low high-density lipoprotein cholesterol, small dense low-density lipoprotein (LDL), and increased apolipoprotein B (apoB) levels, all characteristics of familial combined hyperlipidemia (FCH). Therefore, we explored the role of insulin resistance in FCH lipid phenotype expression. METHODS AND RESULTS FCH was defin...

BACKGROUND Intravenous adenosine infusion produces coronary and systemic vasodilatation, generally leading to systemic hypotension. However, adenosine-induced hypotension during stable hyperemia is heterogeneous, and its relevance to coronary stenoses assessment with fractional flow reserve (FFR) remains largely unknown. METHODS AND RESULTS FFR, coronary flow reserve, and index of microcircul...
