OR-77: Relationships between cardiovascular and metabolic responses to meals

To evaluated the relationship between glucose regulation, insulin secretion and cardiovascular responses in normotensive and hypertensive obese subjects. We studied 12 normotensive (NT-OB) and 8 hypertensive (HT-OB) obese (BMI > 30Kg/m2) men, age 36 ±8 yrs. And ten healthy controls (BMI

We studied 12 normotensive (NT-OB) and 8 hypertensive (HT-OB) obese (BMI &gt; 30Kg/m2) men, age 36 ±8 yrs. And ten healthy controls (BMI &lt;25 kg/m2) matched for age. After overnight fasting, samples for glucose and insulin were drawn at 30 min intervals during 2 h after meals (post-prandial periods) and 60 min during the rest of the 24h (between meals and during the night). AMBP (Spacelab 90207) were performed at 20 min intervals. Subjects ingested a standard diet (2100 Kcal), divided into three meals (breakfast at 8 AM, lunch at 13:30 PM and dinner at 20 PM). At the end of the experiment, we studied the insulin sensitivity by Insulin Supresion Test. Significant postmeal increases in systolic blood pressure(SBP) were observed in the three groups after breakfast (13.2±10, 13.3±4.7, 17.5±7 mmHg for control, NT-OB and HT-OB, respectively) after lunch (13±8.9; 11±7; 19.5±5.4 mmHg for control, NT-OB and HT-OB, respectively) and after dinner (15±9, 17.9±10, 27.9±7 mmHg for control, NT-OB and HT-OB, respectively). Indeed, these SBP increases were significant higher in the OB-HT group as compared with NT-OB and Control groups (p&lt;0.05). We did not find any differences in posprandial variations in diastolic pressure and heart rate among the groups. The magnitude of the postprandial increases in SBP was correlated with the amount of insulin secreted, especially in the HT-OB group (r=0.78 after breakfast, r =0.72 after lunch and r=0.94 after dinner). In the same sense, we found an inversely correlation between insulin sensitivity index and postmeal increase in SBP, specially in the OB-NT group after the dinner (r=−0.84; p&lt;0.05).These findings indicate that there is a quantitative relationship between posprandial insulin secretion and blood pressure in normotensive and hypertensive obese young subjects.</description><identifier>ISSN: 0895-7061</identifier><identifier>EISSN: 1941-7225</identifier><identifier>DOI: 10.1016/S0895-7061(03)00160-2</identifier><identifier>CODEN: AJHYE6</identifier><language>eng</language><publisher>Oxford: Oxford University Press</publisher><subject>Insulin ; Obesity ; Systolic Blood Pressure</subject><ispartof>American journal of hypertension, 2003-05, Vol.16 (S1), p.35A-35A</ispartof><rights>Copyright Nature Publishing Group May 2003</rights><lds50>peer_reviewed</lds50><woscitedreferencessubscribed>false</woscitedreferencessubscribed></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><link.rule.ids>314,776,780,27903,27904</link.rule.ids></links><search><creatorcontrib>González-Albarrán, Olga</creatorcontrib><creatorcontrib>Fraile, Juana</creatorcontrib><creatorcontrib>de Tejada, Gema García Romero</creatorcontrib><creatorcontrib>Vieitez, Paula</creatorcontrib><creatorcontrib>Ruiz, Esther</creatorcontrib><creatorcontrib>Gómez, Oscar</creatorcontrib><creatorcontrib>Sancho, José M.</creatorcontrib><creatorcontrib>García-Robles, Rafael</creatorcontrib><title>OR-77: Relationships between cardiovascular and metabolic responses to meals</title><title>American journal of hypertension</title><addtitle>AJH</addtitle><description>To evaluated the relationship between glucose regulation, insulin secretion and cardiovascular responses in normotensive and hypertensive obese subjects.
