Why the study?
Are obesity and serum cholesterol levels differentially associated with essential versus renovascular hypertension?
Are obesity and serum cholesterol levels differentially associated with essential versus renovascular hypertension?
Obesity is specifically associated with essential hypertension rather than renovascular hypertension, while serum cholesterol is independent of both.
Obesity counseling may retain relevance in essential hypertension; cross-sectional data leave open causality and extension to renovascular cases.
The association of obesity with hypertension has been found to hold true for 414 patients with proved essential hypertension; 187 patients with renovascular hypertension are much closer to their actuarially desirable weight. We hypothesize that in obese patients who are genetically predisposed, the production of "essential" hypertension may involve a synergism between a high dietary salt and carbohydrate intake. The serum cholesterol level was found to be age-dependent but unrelated to the presence of either hypertension or obesity.
