Blood pressure in adolescence, adipokines and inflammation in young adults. The rio de janeiro study.

BACKGROUND: The impact of blood pressure (BP) during adolescence on other cardiovascular risk factors in young adults is important for the primary prevention. OBJECTIVE: To evaluate BP, anthropometric indexes, metabolic and inflammatory profiles in young individuals stratified by their BP behavior recorded for 18 years. METHODS: A total of 116 individuals, of whom 63 were males, from the Rio de Janeiro study (follow-up of 17.76 ± 1.63 years), were assessed at two moments: A1 (12.40 ± 1.49 years) and A2 (30.09 ± 2.01 years). The 116 individuals were divided into two groups: GN (n = 71), of participants with normal BP at A1; and GH (n = 45), of those with abnormal BP at A1. BP, weight, height and body mass index (BMI) were measured at A1 and A2. At A2, abdominal circumference (AC) and laboratory, metabolic and inflammatory variables were included. RESULTS: 1) No difference was observed between the groups as regards age and gender; 2) At A2, GH showed higher mean weight, BMI, BP, insulin, HOMA-IR (p < 0.001), leptin (p < 0.02), apolipoprotein B100 and A1 (p < 0.02), apolipoprotein B100 / apolipoprotein A1 ratio (p < 0.010); and higher prevalences of overweight/obesity (p < 0.001), of increased AC (p < 0.001) and of hypertension (p < 0.02); 3) No difference was observed between the groups as regards the inflammatory variables; 4) There was a positive correlation of BP at A1 with BP, BMI, insulin, leptin and HOMA-IR at A2 (p < 0.05). CONCLUSION: BP in adolescence was associated with higher values of BP, and anthropometric and metabolic variables in young adulthood, but not with inflammatory variables.

Pulse wave velocity, blood pressure and adipocytokines in young adults: the Rio de Janeiro study.

BACKGROUND: Data on noninvasive vascular assessment and their association with cardiovascular risk variables are scarce in young individuals. OBJECTIVE: To evaluate the association between pulse wave velocity and blood pressure, anthropometric and metabolic variables, including adipocytokines, in young adults. METHODS: A total of 96 individuals aged 26 to 35 years (mean 30.09 ± 1.92; 51 males) were assessed in the Rio de Janeiro study. Pulse wave velocity (Complior method), blood pressure, body mass index, glucose, lipid profile, leptin, insulin, adiponectin and insulin resistance index (HOMA-IR) were analyzed. Subjects were stratified into three groups according to the PWV tertile for each gender. RESULTS: The group with the highest pulse wave velocity (PWV) tertile showed higher mean systolic and diastolic blood pressure, mean blood pressure, body mass index, insulin, and HOMA-IR, as well as lower mean adiponectin; higher prevalence of diabetes mellitus/glucose intolerance and hyperinsulinemia. There was a significant positive correlation of PWV with systolic blood pressure, diastolic blood pressure, pulse pressure and mean blood pressure, body mass index, and LDL-cholesterol, and a negative correlation with HDL-cholesterol and adiponectin. In the multiple regression model, after adjustment of HDL-cholesterol, LDL-cholesterol and adiponectin for gender, age, body mass index and mean blood pressure, only the male gender and mean blood pressure remained significantly correlated with PWV. CONCLUSION: PWV in young adults showed a significant association with cardiovascular risk variables, especially in the male gender, and mean blood pressure as important determinant variables. The findings suggest that PWV measurement can be useful for the identification of vascular impairment in this age group.

Pulse wave velocity in young adults: study of Rio de Janeiro.

BACKGROUND: Pulse wave velocity (PWV) can be a marker of cardiovascular impairment, but there are few studies in young adults. OBJECTIVE: To evaluate the association between blood pressure (BP), current anthropometric and metabolic variables and those obtained 13 years earlier, in childhood and adolescence, with PWV. METHODS: Sixty individuals were followed longitudinally and split into two groups according to the percentile of blood pressure (BP) obtained 13 years earlier: Group 1 (G1): BP percentile < 50 (n = 25, 11M, 26.4 years old) and Group 2 (G2): BP > 95 percentile (n = 35, 19M, 25.4 years old). The individuals underwent clinical evaluation, laboratory analysis and measurements of PWV through the Complior method. RESULTS: G1 showed higher mean age; G2 showed greater mean weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), PWV and blood glucose, and lower mean HDL-cholesterol. SBP, MAP and heart rate (HR) obtained during childhood and adolescence significantly correlated with PWV. Current weight, height, waist-hip ratio, SBP, DBP, pulse pressure (PP), MAP and creatinine presented a positive and significant correlation with PWV. A comparison of the average PWV adjusted for SBP, DBP, SBP and DBP, MAP and PP showed no statistically significant difference between groups. CONCLUSION: The percentile of BP in childhood/adolescence related to arterial distensibility assessed by PWV 13 years later. Changes in PWV can be identified in young individuals suggesting that early vascular impairment may be present in this age group, also related to blood pressure, anthropometric and metabolic variables.

Association between uric acid and cardiovascular risk variables in a non-hospitalized population.

BACKGROUND: The association between uric acid (UA) and cardiovascular risk variables remains a controversial issue in epidemiological studies. OBJECTIVE: To evaluate the association between UA, blood pressure (BP), anthropometric indices and metabolic variables in a non-hospitalized population stratified by UA quintiles. METHODS: A cross-sectional observational study evaluated 756 individuals (369 males), aged 50.3 ± 16.12 years, divided in UA quintiles. BP, body mass index (BMI), abdominal circumference (AC), UA, glucose, insulin, HOMA-IR, total cholesterol (TC), LDL-c, HDL-c, triglycerides (TG) and creatinine (C) levels were obtained. The estimated glomerular filtration rate (eGFR) was calculated and arterial hypertension (AH) was considered when BP > 140x90 mmHg, overweight/obesity (OW/O) was considered when BMI > 25 kg/m² and metabolic syndrome (MS) was established according to the I Brazilian Guideline of MS. RESULTS: 1) There was no difference between the groups regarding the distribution by sex and age range; 2) The highest UA quintiles presented higher mean age (p < 0.01), BMI, AC (p < 0.01), SBP, DBP (p < 0.001), TC, LDL-c, TG (p < 0.01), C and eGFR (p < 0.001) and lower mean HDL-c (p < 0.001); 3) The group with the highest UA quintile showed higher prevalence of AH, OW/O and MS (p < 0.001); 4) Higher percentages of the lowest quintiles of insulin (p < 0.02) and HOMA-IR (p < 0.01) were observed with the lowest quintiles of UA; 5) A logistic regression analysis showed that UA and the variables that compose MS were associated with the occurrence of MS (p < 0.01). CONCLUSION: Higher quintiles of uric acid were associated with a worse cardiovascular risk profile and a worse kidney function profile in the non-hospitalized population sample studied.

Importance of HDL-c for the occurrence of cardiovascular disease in the elderly.

BACKGROUND: Studies on the impact of HDL-c and the occurrence of cardiovascular disease (CV) in the elderly are scarce. OBJECTIVE: To evaluate the clinical and laboratory variables and the occurrence of CV events in elderly patients stratified according to the behavior of HDL-c during an eight-year follow up. METHODS: We evaluated 81 elderly patients, mean age of 68.51 +/- 6.32 years (38.2% male), in two stages (A1 and A2), with a minimum interval of five years. The subjects were divided into 3 groups according to HDL-c levels: normal HDL-c in both assessments (NG) (n = 31), low HDL-c in both assessments (LG) (n = 21) and variable HDL-c in A1 and A2 (VG) (n = 29). Main CV events were recorded: coronary heart disease (angina, myocardial infarction, percutaneous / surgical myocardial revascularization), stroke, transient ischemic attack, carotid disease, dementia and heart failure. RESULTS: The groups did not differ in gender and age in A1 and A2. Mean triglyceride levels were lower in the NG in A1 (p = 0.027) and A2 (p = 0.016) than in the LG. The distribution of CV events was as follows: 13 events in the NG (41.9%), 16 (76.2%) in the LG, and 12 (41.4%) in the VG (chi2 = 7.149, p = 0.024). The logistic regression analysis showed that the older the patient (OR = 1.187, p = 0.0230) and the lower the HDL-c (OR = 0.9372, p = 0.0102), the greater the occurrence of events CV. CONCLUSION: Permanently low HDL-c during eight years of monitoring is a risk factor for the development of CV events in the elderly.

Blood pressure in young individuals as a cardiovascular risk marker. The Rio de Janeiro study.

BACKGROUND: The study of the cardiovascular risk variables in young populations is fundamental to establish primary prevention strategies. OBJECTIVE: To evaluate the blood pressure (BP), anthropometric and metabolic profile in young individuals from The Rio de Janeiro Study, followed by 17 years. METHODS: A total of 115 individuals (64 males) were evaluated at three different moments (follow-up: 212.23+/-16.0 months): A1 (12.97+/-1.48 years), A2 (21.90+/-1.71 years) and A3 (30.65+/-2.00 years) and divided in two groups: NG (n=84) with at least two normal BP measurements at the three assessments; HG (n=31) with at least two abnormal BP measurements at the three assessments. BP and body mass index (BMI) were obtained at the three assessments. Levels of glucose, triglycerides, total cholesterol and fractions were obtained at A2 and A3. Abdominal circumference (AC) was obtained only at A3. RESULTS: 1) The means of BP, BMI and AC (p<0.0001) as well as the prevalence of systemic arterial hypertension (SAH) and overweight/obesity (O/O) (p<0.003) were higher in the HG at the three assessments; 2) The means of LDL-c and glycemia (p<0.05) at A2 and the prevalence of metabolic syndrome (MS) at A3 were higher in the HG; 3) the association SAH+O/O was more prevalent in the HG, whereas the association NBP+NBMI was more prevalent in the NG (p<0.0001) at the three assessments; 4) SAH at A1 (RR=5.20 = 5.20; p<0.0007), male gender (RR=5.26 = 5.26; p<0.0019) and OO at A1 (RR=3.40 = 3.40; p<0.0278) determined an increased risk for AH at the young adult life (A3). CONCLUSION: After 17 years of follow-up, the BP of young individuals showed a significant association with the cardiovascular risk variables and the occurrence of MS at the young adult life.

Velocidade da onda de pulso, pressão arterial e adipocitocinas em adultos jovens: estudo do Rio de Janeiro / Pulse wave velocity, blood pressure and adipocytokines in young adults: the Rio de Janeiro study

FUNDAMENTO: Dados sobre a avaliação não invasiva vascular e suas relações com variáveis de risco cardiovascular são escassos em jovens. OBJETIVO: Avaliar a relação entre a velocidade de onda de pulso e a pressão arterial,variáveis antropométricas e metabólicas, incluindo as adipocitocinas, em indivíduos adultos jovens. MÉTODOS: Foram avaliados 96 indivíduos (51 homens) do estudo do Rio de Janeiro, de 26 a 35 anos (média 30,09 ± 1,92). Foram obtidos a velocidade de onda de pulso (método Complior), pressão arterial, índice de massa corporal, glicose, perfil lipídico, leptina, insulina, adiponectina e o índice de resistência à insulina HOMA-IR. Os indivíduos foram estratificados em três grupos segundo o tercil da VOP para cada sexo. RESULTADOS: O grupo com maior tercil de VOP mostrou maiores médias de pressão arterial sistólica, pressão arterial diastólica, pressão arterial média, índice de massa corporal, insulina, HOMA-IR e menores médias de adiponectina, além de maiores prevalências de diabetes mellitus/intolerância à glicose e hiperinsulinemia. Houve correlação significativa e positiva da velocidade da onda de pulso com pressão arterial sistólica, pressão arterial diastólica, pressão de pulso e pressão arterial média, índice de massa corporal, e LDL-colesterol e negativa com HDL-colesterol e adiponectina. Em modelo de regressão múltipla, após ajuste do HDL-colesterol, LDL-colesterol e adiponectina para sexo, idade, índice de massa corporal e pressão arterial média, apenas o sexo masculino e a pressão arterial média mantiveram correlação significativa com a velocidade de onda de pulso. CONCLUSÃO: A velocidade de onda de pulso em adultos jovens mostrou relação significativa com variáveis de risco cardiovascular, destacando-se o sexo masculino e a pressão arterial média como importantes variáveis no seu determinismo. Os achados sugerem que a medida da VOP pode ser útil para a identificação do acometimento vascular nessa faixa etária.

Heart failure in the elderly

The aging of the population is, currently, a major phenomenon, drawing the attention of a number of investigators. The significantincrease of life expectancies over the past few decades, in addition to social and economic consequences, has lead to a major change in themorbidity and mortality profile of elders. Heart failure (HF) is a condition in which the heart can not pump enough blood to meet the body'sneeds. HF is predominantly a disorder of the elderly with rates increasing exponentially. The prevalence of HF approximately doubles witheach decade of life. As people live longer, the occurrence of HF rises, as well as other conditions that complicate its treatment. Impaired heartfunction implies a reduced duration of survival. Fortunately, many factors that can prevent HF and improve outcome are known and can beapplied at any stage. This review emphasizes the importance of factors inherent in aging itself, focusing on heart disease, particularly as adisease of aging, can help critically refine management of this acute and chronic disease, as well as foster preventive strategies to reduce theincidence of this common malady.

A velocidade da onda de pulso em jovens: estudo do Rio de Janeiro / Pulse wave vocity in young adults: study of Rio de Janeiro / La velocidad de la onda de pulso en jóvenes: estudio de Rio de Janeiro

FUNDAMENTO: A velocidade da onda de pulso (VOP) pode ser marcador de comprometimento cardiovascular, porém existem poucos estudos em adultos jovens. OBJETIVO: Avaliar a associação da pressão arterial (PA), variáveis antropométricas e metabólicas, atuais e obtidas 13 anos antes, na infância e adolescência, com a VOP. MÉTODOS: Sessenta indivíduos foram acompanhados longitudinalmente e estratificados em dois grupos segundo o percentil da pressão arterial (PA) obtido 13 anos antes: Grupo 1 (G1): percentil da PA < 50 (n = 25, 11M, 26,4 anos) e Grupo 2 (G2): percentil da PA > 95 (n = 35, 19M, 25,4 anos). Foram submetidos a avaliação clínica, análise laboratorial e medidas da VOP pelo método Complior. RESULTADOS: G1 apresentou maior média de idade; G2 exibiu maior média de: peso, PA sistólica (PAS), PA diastólica (PAD), PA média (PAM), VOP e glicemia, e menor média de HDL-colesterol. PAS, PAM e frequência cardíaca (FC) obtidas na infância e adolescência apresentaram correlação significativa com a VOP. Peso, altura, cintura, relação cintura/quadril, PAS, PAD, pressão de pulso (PP), PAM e creatinina atuais apresentaram correlação positiva e significativa com a VOP. A comparação das médias de VOP ajustadas pela PAS, PAD, PAS e PAD, PAM e PP não mostrou diferença estatisticamente significativa entre os grupos. CONCLUSÃO: O percentil da PA na infância/adolescência mostrou-se relacionado à distensibilidade arterial, avaliada pela VOP, 13 anos após. Alterações da VOP podem ser identificadas em indivíduos jovens, sugerindo que o comprometimento vascular precoce pode estar presente nessa faixa etária, relacionado também a pressão arterial, variáveis antropométricas e metabólicas.

BACKGROUND: Pulse wave velocity (PWV) can be a marker of cardiovascular impairment, but there are few studies in young adults. OBJECTIVE: To evaluate the association between blood pressure (BP), current anthropometric and metabolic variables and those obtained 13 years earlier, in childhood and adolescence, with PWV. METHODS: Sixty individuals were followed longitudinally and split into two groups according to the percentile of blood pressure (BP) obtained 13 years earlier: Group 1 (G1): BP percentile < 50 (n = 25, 11M, 26.4 years old) and Group 2 (G2): BP > 95 percentile (n = 35, 19M, 25.4 years old). The individuals underwent clinical evaluation, laboratory analysis and measurements of PWV through the Complior method. RESULTS: G1 showed higher mean age; G2 showed greater mean weight, systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), PWV and blood glucose, and lower mean HDL-cholesterol. SBP, MAP and heart rate (HR) obtained during childhood and adolescence significantly correlated with PWV. Current weight, height, waist-hip ratio, SBP, DBP, pulse pressure (PP), MAP and creatinine presented a positive and significant correlation with PWV. A comparison of the average PWV adjusted for SBP, DBP, SBP and DBP, MAP and PP showed no statistically significant difference between groups. CONCLUSION: The percentile of BP in childhood/adolescence related to arterial distensibility assessed by PWV 13 years later. Changes in PWV can be identified in young individuals suggesting that early vascular impairment may be present in this age group, also related to blood pressure, anthropometric and metabolic variables.

RESULTADOS: G1 presentó un promedio mayor de edad; G2 mostró un promedio mayor de: peso, PA sistólica (PAS), PA diastólica (PAD), PA promedio (PAP), VOP y glucemia, y menor promedio de HDL-colesterol. La PAS, PAP y la frecuencia cardíaca (FC), obtenidas en la infancia y en la adolescencia presentaron una correlación significativa con la VOP. El peso, altura, cintura, relación cintura/cadera, PAS, PAD, la presión de pulso (PP), PAP y la creatinina actuales, presentaron una correlación positiva y significativa con la VOP. La comparación de los promedios de VOP ajustados por las PAS, PAD, PAS y PAD, PAP y PP no arrojó ninguna diferencia estadísticamente significativa entre los grupos. CONCLUSIÓN: El percentil de la PA en la infancia/adolescencia tuvo una relación con la distensibilidad arterial, evaluada por la VOP, 13 años después. Las alteraciones de la VOP pueden ser identificadas en individuos jóvenes, sugiriendo que el compromiso vascular en edad temprana, puede estar presente en esa franja etaria, relacionando también la presión arterial, las variables antropométricas y metabólicas.

CONCLUSÃO: Maiores quintis de ácido úrico associaram-se a pior perfil de risco cardiovascular e a pior perfil de função renal na amostra populacional não hospitalar estudada.

BACKGROUND: The association between uric acid (UA) and cardiovascular risk variables remains a controversial issue in epidemiological studies. OBJECTIVE: To evaluate the association between UA, blood pressure (BP), anthropometric indices and metabolic variables in a non-hospitalized population stratified by UA quintiles. METHODS: A cross-sectional observational study evaluated 756 individuals (369 males), aged 50.3 ± 16.12 years, divided in UA quintiles. BP, body mass index (BMI), abdominal circumference (AC), UA, glucose, insulin, HOMA-IR, total cholesterol (TC), LDL-c, HDL-c, triglycerides (TG) and creatinine (C) levels were obtained. The estimated glomerular filtration rate (eGFR) was calculated and arterial hypertension (AH) was considered when BP > 140x90 mmHg, overweight/obesity (OW/O) was considered when BMI > 25 kg/m² and metabolic syndrome (MS) was established according to the I Brazilian Guideline of MS. RESULTS: 1) There was no difference between the groups regarding the distribution by sex and age range; 2) The highest UA quintiles presented higher mean age (p < 0.01), BMI, AC (p < 0.01), SBP, DBP (p < 0.001), TC, LDL-c, TG (p < 0.01), C and eGFR (p < 0.001) and lower mean HDL-c (p < 0.001); 3) The group with the highest UA quintile showed higher prevalence of AH, OW/O and MS (p < 0.001); 4) Higher percentages of the lowest quintiles of insulin (p < 0.02) and HOMA-IR (p < 0.01) were observed with the lowest quintiles of UA; 5) A logistic regression analysis showed that UA and the variables that compose MS were associated with the occurrence of MS (p < 0.01). CONCLUSION: Higher quintiles of uric acid were associated with a worse cardiovascular risk profile and a worse kidney function profile in the non-hospitalized population sample studied.
