Abstract

Obesity derived from intra-abdominal fat deposition tends to increase hormonal and cytokine production, thus worsening insulin sensitivity and leading to endothelial dysfunction. Hyperinsulinemia is considered an independent risk factor for ischemic heart disease and cause of endothelial dysfunction in healthy individuals. To assess the impact of different degrees of insulin resistance, measured by HOMA-IR (Homeostasis Model Assessment of Insulin Resistance), on endothelial function in obese, non-diabetic patients without prior history of cardiovascular events and different metabolic syndrome components. Forty obese individuals were submitted to anthropometric measurements, BP measurements at office and ABPM and laboratory tests, in addition to non-invasive ultrasound assessment of endothelial function. Patients were divided into 3 groups according to the level of insulin resistance: patients with HOMA-IR values from 0.590 to 1.082 were assigned to Group 1 (n=13), from 1.083 to 1.410 to Group 2 (n=14) and from 1.610 to 2.510 to Group 3 (n=13). We found a significant difference in flow-mediated dilation in group 3 compared to group 1 (9.2 ± 7.0 vs 18.0 ± 7.5 %, p=0.006). There was a negative correlation between endothelial funct...Continue Reading

Cardiovascular Disease Pathophysiology

Cardiovascular disease involves several different processes that contribute to the pathological mechanism, including hyperglycemia, inflammation, atherosclerosis, hypertension and more. Vasculature stability plays a critical role in the development of the disease. Discover the latest research on cardiovascular disease pathophysiology here.
