[Cardiovascular risk factors in an Arab and Hispanic working population]. / Factores de riesgo cardiovascular en una población laboral árabe e hispana.

318 records of male workers, 169 Spanish and 149 Arab were retrospectively studied in 1987 at the "Gabinete de Seguridad e Higiene en el Trabajo" (Council for Safety and Hygiene in the Workplace) in Ceuta in order to prove the hypothesis that 2 different ethnic groups living in the same geographic area have a non-equal distribution of cardiovascular risk factors. The Spanish group showed a higher prevalence in blood hypertension, diabetes, glucose intolerance, obesity and alcohol intake, compared to the Arab group. Smoking and high levels of seric cholesterol were similar in both groups, however, medium levels of seric cholesterol were lower in the Arab group. Family histories of cardiovascular disease were very rare in the latter mentioned group. These observations suggested a major predisposition to ischemic cardiopathy in the Spanish group.

Lipids and lipoprotein changes after heart and liver transplantation in a patient with homozygous familial hypercholesterolemia.

Changes in lipids and lipoprotein fractions were studied 6 months after a combined heart and liver transplantation in a patient with terminal ischemic heart disease due to homozygous familial hypercholesterolemia. The double transplant was followed by striking decreases in total and low-density-lipoprotein cholesterol levels (-71% and -79%) and content of apolipoprotein B in the low-density-lipoprotein fraction (-74%). There was also an increase in high-density-lipoprotein cholesterol (+7.8%). These changes are greater than those reported with portacaval shunt or plasma exchange. Liver transplantation may be considered in selected patients with homozygous familial hypercholesterolemia.
