Obese women with polycystic ovary syndrome (PCO), characterized by hormonal and metabolic abnormalities, are thought to be at particularly increased cardiovascular risk.<\/jats:p>\n               <jats:p>Objectives: We sought to determine the influence of IR on LV function in obese young women with and without PCO and without other comorbidities.<\/jats:p>\n               <jats:p>Design: This was a cross-sectional study.<\/jats:p>\n               <jats:p>Setting: The study was performed at a university hospital.<\/jats:p>\n               <jats:p>Patients: A total of 150 women aged younger than 40 yr with a body mass index (BMI) of 30 kg\/m2 or more was classified into three groups: with both PCO and IR, without PCO and with IR, and without either PCO or IR.<\/jats:p>\n               <jats:p>Main Outcome Measures: Tissue Doppler-derived myocardial velocities, strain-rate and strain, and metabolic and hormonal measurements were calculated.<\/jats:p>\n               <jats:p>Results: Subclinical impairment of LV systolic and diastolic function as indicated by lower peak strain (P &amp;lt; 0.001), peak systolic strain rate (P &amp;lt; 0.001), peak early diastolic strain rate (P &amp;lt; 0.001), and peak early diastolic velocity (P &amp;lt; 0.01) was demonstrated in both groups with IR. IR subjects with and without PCO did not differ in any LV function indices. Strain was independently associated with fasting insulin (\u03b2 = \u22120.39; P &amp;lt; 0.001), urinary albumin excretion (UAE) (\u03b2 = \u22120.36; P &amp;lt; 0.001), and BMI (\u03b2 = \u22120.22; P &amp;lt; 0.03), and peak early diastolic strain rate was associated with UAE (\u03b2 = \u22120.35; P &amp;lt; 0.001), fasting insulin (\u03b2 = \u22120.24; P &amp;lt; 0.02), BMI (\u03b2 = \u22120.23; P &amp;lt; 0.02), and SHBG (\u03b2 = 0.20; P &amp;lt; 0.04).<\/jats:p>\n               <jats:p>Conclusions: In obese young women, fasting insulin, BMI, SHBG, and UAE are independent correlates of impaired LV performance. The contribution of PCO to LV function abnormalities is linked to IR, but not to other hormonal aberrations associated with this condition.<\/jats:p>","DOI":"10.1210\/jc.2008-1017","type":"journal-article","created":{"date-parts":[[2008,8,6]],"date-time":"2008-08-06T03:48:58Z","timestamp":1217994538000},"page":"3748-3754","source":"Crossref","is-referenced-by-count":35,"title":["Subclinical Impairment of Left Ventricular Function in Young Obese Women: Contributions of Polycystic Ovary Disease and Insulin Resistance"],"prefix":"10.1210","volume":"93","author":[{"given":"Wojciech","family":"Kosmala","sequence":"first","affiliation":[{"name":"Departments of Cardiology (W.K., R.P., M.P.-K.), Wroclaw Medical University, 50-367 Wroc\u0142aw"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trisha M.","family":"O'Moore-Sullivan","sequence":"additional","affiliation":[{"name":"Poland Diamantina Institute and School of Medicine (T.M.O.-S., T.H.M.), University of Queensland and Department of Diabetes and Endocrinology, Princess Alexandra Hospital, Brisbane Q4102, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rafal","family":"Plaksej","sequence":"additional","affiliation":[{"name":"Departments of Cardiology (W.K., R.P., M.P.-K.), Wroclaw Medical University, 50-367 Wroc\u0142aw"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Justyna","family":"Kuliczkowska-Plaksej","sequence":"additional","affiliation":[{"name":"Endocrinology (J.K.-P.), Wroclaw Medical University, 50-367 Wroc\u0142aw"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monika","family":"Przewlocka-Kosmala","sequence":"additional","affiliation":[{"name":"Departments of Cardiology (W.K., R.P., M.P.-K.), Wroclaw Medical University, 50-367 Wroc\u0142aw"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas H.","family":"Marwick","sequence":"additional","affiliation":[{"name":"Poland Diamantina Institute and School of Medicine (T.M.O.-S., T.H.M.), University of Queensland and Department of Diabetes and Endocrinology, Princess Alexandra Hospital, Brisbane Q4102, Australia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","reference":[{"key":"2020071614165333400_R1","doi-asserted-by":"crossref","first-page":"305","DOI":"10.1056\/NEJMoa020245","article-title":"Obesity and the risk of heart failure.","volume":"347","author":"Kenchaiah","year":"2002","journal-title":"N Engl J Med"},{"key":"2020071614165333400_R2","doi-asserted-by":"crossref","first-page":"2191","DOI":"10.1161\/01.CIR.0000127959.28627.F8","article-title":"Effect of obesity and insulin resistance on myocardial substrate metabolism and efficiency in young women.","volume":"109","author":"Peterson","year":"2004","journal-title":"Circulation"},{"key":"2020071614165333400_R3","doi-asserted-by":"crossref","first-page":"3081","DOI":"10.1161\/01.CIR.0000147184.13872.0F","article-title":"Alterations of left ventricular myocardial characteristics associated with obesity.","volume":"110","author":"Wong","year":"2004","journal-title":"Circulation"},{"key":"2020071614165333400_R4","doi-asserted-by":"crossref","first-page":"1616","DOI":"10.1038\/oby.2004.201","article-title":"Adapted changes in left ventricular structure and function in severe uncomplicated obesity.","volume":"12","author":"Iacobellis","year":"2004","journal-title":"Obes Res"},{"key":"2020071614165333400_R5","doi-asserted-by":"crossref","first-page":"334","DOI":"10.1001\/jama.294.3.334","article-title":"Insulin resistance and risk of congestive heart failure.","volume":"294","author":"Ingelsson","year":"2005","journal-title":"JAMA"},{"key":"2020071614165333400_R6","doi-asserted-by":"crossref","first-page":"1063","DOI":"10.1016\/j.echo.2006.03.033","article-title":"Obesity cardiomyopathy: is it a reality?
