Prevalência de hipertensão arterial em Adventistas do Sétimo Dia da capital e do interior paulista

FUNDAMENTO: Sabe-se que hábitos de vida inadequados favorecem a hipertensão, e os adventistas preconizam hábitos saudáveis. OBJETIVO: Avaliar a prevalência da hipertensão nos adventistas do sétimo dia na capital e no interior paulistas. MÉTODOS: Foram estudados 264 adventistas (41,17 ± 15,27 anos, 59,8% mulheres, com alto nível de religiosidade avaliada pela escala Duke-DUREL). A medida da pressão arterial foi realizada com aparelho automático validado. Nível de significância adotado foi p < 0,05. Resultados: A prevalência total de hipertensão foi 22,7%, (27,4% no interior e 15% na capital). Os adventistas da capital diferiram dos do interior (p < 0,05), respectivamente, quanto: escolaridade superior (62% vs 36,6%); ter vínculo empregatício (44%) vs autônomos (40,9%); renda familiar (8,39 ± 6,20 vs 4,59 ± 4,75 salários mínimos) e renda individual (4,54 ± 5,34 vs 6,35 ± 48 salários mínimos); casal responsável pela renda familiar (35% vs 39,6%); vegetarianismo (11% vs 3%); pressão arterial (115,38 ± 16,52/68,74 ± 8,94 vs 123,66 ± 19,62/74,88 ± 11,85 mmHg); etnia branca (65% vs 81,1%); casados (53% vs 68,9%); menor apoio social no domínio material (15,7 ± 5,41 vs 16,9 ± 4,32) e lembrar da última vez que mediu a pressão arterial (65% vs 48,8%). A análise multivariada associou hipertensão com: 1) vegetarianismo (OR 0,051, IC95% 0,004-0,681), 2) escolaridade (OR 5,317, IC95% 1,674-16,893), 3) lembrar quando mediu a pressão (OR 2,725, IC95% 1,275-5,821), 4) aposentado (OR 8,846, IC95% 1,406-55,668), 5) responsável pela renda familiar (OR 0,422, IC95% 0,189-0,942). CONCLUSÃO: A prevalência de hipertensão dos adventistas foi menor se comparada com estudos nacionais, sendo menor na capital em relação ao interior possivelmente por melhores condições socioeconômicas e hábitos de vida.

Lipoprotein (a): Structure, Pathophysiology and Clinical Implications

The chemical structure of lipoprotein (a) is similar to that of LDL, from which it differs due to the presence of apolipoprotein (a) bound to apo B100 via one disulfide bridge. Lipoprotein (a) is synthesized in the liver and its plasma concentration, which can be determined by use of monoclonal antibody-based methods, ranges from < 1 mg to > 1,000 mg/dL. Lipoprotein (a) levels over 20-30 mg/dL are associated with a two-fold risk of developing coronary artery disease. Usually, black subjects have higher lipoprotein (a) levels that, differently from Caucasians and Orientals, are not related to coronary artery disease. However, the risk of black subjects must be considered. Sex and age have little influence on lipoprotein (a) levels. Lipoprotein (a) homology with plasminogen might lead to interference with the fibrinolytic cascade, accounting for an atherogenic mechanism of that lipoprotein. Nevertheless, direct deposition of lipoprotein (a) on arterial wall is also a possible mechanism, lipoprotein (a) being more prone to oxidation than LDL. Most prospective studies have confirmed lipoprotein (a) as a predisposing factor to atherosclerosis. Statin treatment does not lower lipoprotein (a) levels, differently from niacin and ezetimibe, which tend to reduce lipoprotein (a), although confirmation of ezetimibe effects is pending. The reduction in lipoprotein (a) concentrations has not been demonstrated to reduce the risk for coronary artery disease. Whenever higher lipoprotein (a) concentrations are found, and in the absence of more effective and well-tolerated drugs, a more strict and vigorous control of the other coronary artery disease risk factors should be sought.
