Inflammation, Obesity and the Metabolic Syndrome. Implications in Hispanics.

We report clinical and molecular mechanisms relating the process of inflammation involved in the progression of obesity and the metabolic syndrome, emphasizing the cardiovascular problems developed in Hispanic populations. Namely, the incidence, component characteristics and complications of obesity and metabolic syndrome in island Puerto Ricans are described and evidence is presented supporting the fact that the metabolic syndrome may be milder in Puerto Rico than in the mainland United States because it is characterized by less aggressive coronary artery disease and a relatively normal lipid profile. Moreover, data supports the fact that increased serum cholesterol levels produce less myocardial infarctions in Puerto Rico than in mainland Hispanics and Caucasians. In addition, the incidence of ventricular tachycardia, a complication caused by remodeling and ischemia of the heart, may be lower in Puerto Rico than in the United States, although the prevalence of the metabolic syndrome is higher in the island. On the other hand, there is evidence of a rising epidemic of obesity and vascular inflammation in Puerto Rico that suggests that cardiovascular morbidity and mortality in the island will continue to increase in the future decades.
