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.

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.

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

Studies about the impact of HDL-C levels on the incidence of cardiovascular disease (CVD) in the elderly are scarce. We decided to evaluate the relation of clinical and laboratory variables to the incidence of CVD events in the elderly stratified according to HDL-C behavior in an 8-year follow-up. We assessed 126 elderly (mean age: 70.01±7.24 years; 33.3% were men) on two occasions (assessment 1=A1, and assessment 2=A2), with a minimum of 5-year interval. They underwent clinical and laboratory evaluation and were divided into three groups as follows: (1) GN (n=52), normal HDL-C levels on A1 and A2; (2) GL (n=36), low HDL-C levels on A1 and A2; (3) GV (n=38), HDL-C levels varying from A1 to A2. The following CVD events were observed: coronary artery disease (angina pectoris=AP, myocardial infarction=MI, percutaneous/surgical coronary intervention); stroke; transient ischemic attack=TIA; carotid disease; and heart failure=HF. The groups did not differ in age or gender at A1 and A2. Triglyceride=TG mean levels were lower in GN at A1 (p=0.007) and A2 (p<0.001) than in GL. There were 14 CVD events in GN (26.9%), 23 (63.9%) in GL, and 13 (34.2%) in GV (χ2=12.825; p=0.002). In logistic regression analysis, we observed that the higher the systolic blood pressure (SBP) (odds ratio [OR]=1.0231; p=0.0338) and the lower the HDL-C (OR=0.9363; p=0.0035), the higher the incidence of CVD events. Persistently low HDL-C levels over 8 years of follow-up were a risk factor (RF) for the development of CVD events in the elderly.

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.

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.

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.

Fundamento: O impacto pressão arterial (PA) na adolescência sobre outros fatores de risco cardiovascular em adultos jovens é importante para a prevenção primária. Objetivo: Avaliar a PA, índices antropométricos, perfil metabólico e inflamatório de jovens estratificados pelo comportamento da sua PA obtida há 18 anos. Métodos: Avaliaram-se 116 indivíduos, sendo 63 homes, pertencentes ao estudo do Rio de Janeiro (seguimento 17,76 ± 1,63 anos) em dois momentos: A1 (12,40 ± 1,49 anos) e A2 (30,09 ± 2,01 anos). Os 116 indivíduos foram divididos em dois grupos: GN (n = 71), PA normal em A1; e GH (n = 45): PA anormal em A1. A PA, o peso, a altura e o índice de massa corporal (IMC) foram obtidos em A1 e A2. Em A2, acrescentaram-se a circunferência abdominal (CA) e variáveis laboratoriais, metabólicas e inflamatórias. Resultados: 1) Os grupos não diferiram quanto à idade e sexo; 2) Em A2, GH apresentou maiores médias de peso, IMC, PA, insulina, HOMA-IR (p < 0,001), leptina (p < 0,02), Apolipoproteína B100 e A1 (p < 0,02), relação Apolipoproteína B100 / Apolipoproteína A1 (p < 0,010), maiores prevalências de sobrepeso/obesidade (p < 0,001), da CA aumentada (p < 0,001) e de hipertensão arterial (p < 0,02); 3) Não houve diferença entre os grupos para as variáveis inflamatórias; 4) Houve correlação positiva da PA em A1 com a PA, o IMC, e com a insulina, a leptina e o HOMA-IR em A2 (p < 0,05). Conclusões: A PA na adolescência se associou a maiores valores de PA, variáveis antropométricas e metabólicas na fase adulta jovem, mas não a variáveis inflamatórias. .

OBJECTIVE: The objective of this study was to assess the mean intima-media thickening of carotid arteries of elderly subjects, and its relationship with age, anthropometric measurements, high systolic blood pressure and dyslipidemia. METHODS: In this investigation, 129 subjects were enrolled between 1995 and 1998, age ranging from 29 to 94 years. They were assigned to one of 4 groups, including 2 control groups (group I, of healthy younger subjects; group II of healthy elderly subjects). Groups III and IV included those who presented with isolated systolic hypertension (ISH), and ISH and dyslipidemia, respectively. All subjects were submitted to a medical interview, lab tests with measurement of cholesterol levels, electrocardiogram, and carotid ultrasound. The ultrasound included measurement of the intima-media thickening (IMT) of the carotid arteries, the right carotid artery (RCA) and left carotid artery (LCA), and assessment of the presence of plaques. Blood fat and glucose were measured by a standard method. The results were compared among the groups through statistical tests. The tests employed were: Chi-Square, Pearson's and Likelihood Ratio, Student's t, Mann-Whitney; ANOVA followed by Tukey's test, Kruskal-Wallis nonparametric test, and test for multiple comparisons and Odds Ratio determination (OR). RESULTS: In this investigation, a positive association was observed between aging and IMT. In relation to systolic hypertension, a significant association was observed with IMT (IMT-RCA p = 0.0034; IMT-LCAp = 0.0196; IMT-RLCAp = 0.0299), and with the presence of plaques (PlaqueR p = 0.0110; PlaqueL p = 0.0294; PlaqueRL p = 0.0040). CONCLUSION: This investigation evidenced the important role of aging in IMT, and of systolic hypertension in the IMT and presence of plaque. However, further studies are needed for a better understanding of the actual role of risk factors in aging.

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.
