Definition
1) Gynecoid: pear-shaped; adipose concentrated on the hips and thighs.
2) Android: apple-shaped; adipose mainly on the abdomen. This type has an increased association w/ CAD, HTN, NIDDM, dyslipidemia, and death. Also, increased free fatty acid (FFA) released by adipose and tissues adjacent to it |

|
Term
| In obesity, how does increased blood vloume and plasma volume influence CO? |
|
Definition
Increased CO of 0.1L/min for each kg of fat acquired
Increased CO precedes increased left-sided heart pressure and left ventricular hpertrophy |
|
|
Term
| How do so many obese people get CHF? |
|
Definition
| Their heart rates remain the same, which means CO must be augmented by the increased SV, which results in cardiomegaly, atrial and biventricular dilation, and biventricular hypertrophy. These will contribute to HTN and eventually CHF. |
|
|
Term
| Due to increases in blood volumes, what does this do to preload/afterload? |
|
Definition
There is an increase in pre/afterload which
1) results in increased right atrial pressure,
and
2) increased PA and wedge pressures |
