ABSTRACT

BACKGROUND: Considering the pharmacokinetic and pharmacodynamic aspects of different medications, it is plausible that the age of a smoker could affect the half-life of these drugs. The aim of this study was to compare the effectiveness of smoking cessation drugs (nicotine replacement therapy, bupropion, and varenicline) used either in isolation or in combination in adults under and over 60 years of age. METHODS: Data were collected from 940 Brazilian patients participating in a smoking cessation program. Participants were prescribed smoking cessation medication to be used for at least 12 weeks and were followed for 52 weeks. RESULTS: Cessation rates were significantly different among younger and older participants who were using nicotine replacement therapy (NRT) alone. Being over 60 years of age was significantly associated with increased cessation success among those who used NRT alone (OR 2.34, 95% CI: 1.36 to 4.04, p = 0.002). The effectiveness of varenicline and bupropion were not significantly different according to age groups. CONCLUSION: Using age as a predictor for tailoring smoking cessation drugs might potentially lead to a more individualized prescription of smoking cessation therapy. These results should be tested in randomized controlled trials.

ABSTRACT

BACKGROUND: The aging process promotes a progressive increase in chronic-degenerative diseases. The effect of these diseases on the functional capacity has been well recognized. Another health parameter concerns "quality of life related to health". Among the elderly population, cardiovascular diseases stand out due to the epidemiological and clinical impact. Usually, these diseases have been associated with others. This set of problems may compromise both independence and quality of life in elderly patients who seek cardiologic treatment. These health parameters have not been well contemplated by cardiologists. OBJECTIVE: Evaluating, among the elderly population with cardiovascular disease, which are the most relevant clinical determinants regarding dependence and quality of life. METHODS: This group was randomly and consecutively selected and four questionnaires were applied: HAQ, SF-36, PRIME-MD e Mini Mental State. RESULTS: The study included 1,020 elderly patients, 63.3% women. The group had been between 60 and 97 years-old (mean: 75.56 ± 6.62 years-old). 61.4% were independent or mild dependence. The quality of life total score was high (HAQ: 88.66 ± 2.68). 87.8% of patients had a SF-36 total score > 66. In the multivariate analysis, the association between diagnoses and high degrees of dependence was significant only for previous stroke (p = 0.014), obesity (p < 0.001), lack of physical activity (p = 0.016), osteoarthritis (p < 0.001), cognitive impairment (p < 0.001), and major depression (p < 0.001). Analyzing the quality of life, major depression and physical illness for depression was significantly associated with all domains of the SF-36. CONCLUSION: Among an elderly outpatient cardiology population, dependence and quality of life clinical determinants are not cardiovascular comorbidities, especially the depression.

Fundamento: Com o envelhecimento, a prevalência de doenças crônico-degenerativas sofreu aumento progressivo. A repercussão dessas doenças sobre a capacidade funcional foi reconhecida. Outro parâmetro de saúde é a “qualidade de vida relacionada à saúde”. Na população idosa, as doenças cardiovasculares destacam-se pelo impacto epidemiológico e clínico. Elas, geralmente, vêm associadas a outras afecções. Esse conjunto de problemas pode comprometer a independência e a qualidade de vida do idoso que busca tratamento cardiológico. Objetivo: Avaliar, em uma população de idosos cardiopatas, quais são os determinantes clínicos mais relevantes de dependência e de qualidade de vida. Métodos: O grupo foi selecionado aleatória e consecutivamente, sendo aplicados quatro questionários: HAQ, SF-36, PRIME‑MD e Mini Exame do Estado Mental. Resultados: Incluiu-se 1020 idosos, 63,3% mulheres. O grupo tinha em média 75,56 ± 6,62 anos. 61,4% mostrou-se independente ou com dependência leve. O escore de qualidade de vida foi elevado (HAQ: 88,66 ± 2,68). 87,8% dos pacientes apresentou escore total do SF-36 ≥ 66. À análise multivariada, a associação entre os diagnósticos e graus elevados de dependência foi significante apenas para acidente vascular cerebral prévio (p = 0,014), obesidade (p < 0,001), sedentarismo (p = 0,016), osteoartrite (p < 0,001), déficit cognitivo (p < 0,001), e depressão maior (p < 0,001). Ao analisarmos a qualidade de vida, a depressão maior e a depressão por doença física associou-se significativamente com todos os domínios do SF-36. Conclusão: Em uma população de idosos cardiopatas, os determinantes clínicos mais relevantes de prejuízos para dependência e qualidade de vida foram as comorbidades não cardiovasculares, particularmente a depressão. .

ABSTRACT

OBJECTIVE: Free fatty acid inhibition with trimetazidine (TMZ) improves myocardial metabolism and myocardial ischemia in patients with coronary artery disease (CAD). Because of its effect on myocardial glucose utilization TMZ may represent a therapeutic option in diabetic patients with CAD. Aim of the present study was to evaluate whether the metabolic effect of TMZ may improve episodes of myocardial ischemia in diabetic patients with CAD. RESEARCH DESIGN AND METHODS: We assessed the effect of TMZ on 24 h ambulatory ECG monitoring (AEM) in 30 patients (22 males and 8 females, mean (SE) age 67+/-6.5 years) with NIDDM and ischemic cardiomyopathy. Patients were randomized to receive on top of standard therapy either TMZ (20 mg, tds) or placebo (tds) and were evaluated at baseline and after 6 months. RESULTS: Patients randomized to TMZ or placebo were comparable regarding demographic data, distribution of CAD, and glicated haemoglobin levels. TMZ significantly reduced the number of episodes of transient myocardial ischemia (-24% compared to baseline, p<0.01; -27% compared to placebo, p<0.01), and Total Ischemic Burden (-28% compared to baseline, p<0.01; -29% compared to placebo, p<0.01). TMZ also significantly reduced the number of silent episodes of myocardial ischemia (-42% compared to baseline and -39% compared to placebo, p<0.01) and the time of silent myocardial ischemia/24 h (-37% compared to baseline and -35% compared to placebo, p<0.01). No significant changes in heart rate were detected between baseline, placebo and TMZ evaluations. CONCLUSIONS: TMZ is effective in reducing silent and symptomatic episodes of transient myocardial ischemia in diabetic patients with CAD on standard anti-anginal therapy.

ABSTRACT

OBJECTIVE: To study the prognostic value of exercise stress test variables in elderly patients with coronary atherosclerosis and exercise-induced ischemia. METHODS: Sixty-four elderly patients (61 men, 73 +/- 5 years old) with coronary atherosclerosis, verified by cardiac catheterization, that were clinically stable, had a left ventricle ejection fraction greater than or equal to 0.40 and developed myocardial ischemia during the exercise stress test were studied. The patients were evaluated every six months for cardiac events (death, myocardial infarction, unstable angina, angioplasty and myocardial revascularization). RESULTS: After a mean follow-up period of 48 months, 23 (36%) patients suffered cardiac events. There was no clinical or angiographical differences among the patients that suffered cardiac events and those that did not. Using multivariate analysis, the presence of chest pain during the exercise stress test (relative risk 2.668, p = 0.031) and the heart rate at the onset of ischemia (relative risk 0.966, p = 0.009) were associated with cardiac events. CONCLUSION: In this elderly population, the presence of chest pain during the exercise stress test and the heart rate at the onset of ischemia were associated with cardiac events. These variables could be useful for risk evaluation in patients with stable coronary atherosclerosis.

ABSTRACT

OBJETIVO: Estudar o valor prognóstico das variáveis do teste ergométrico em pacientes idosos com doença aterosclerótica coronariana e isquemia induzida pelo esforço. MÉTODOS: Foram estudados 64 pacientes idosos (61 homens, idade de 73 ± 5 anos) com doença aterosclerótica coronariana, comprovada por coronariografia, clinicamente estável, fração de ejeção de ventrículo esquerdo maior ou igual a 0,40 e isquemia miocárdica durante o teste ergométrico. A cada seis meses, os pacientes foram avaliados para eventos cardíacos (morte, infarto do miocárdio, angina instável, angioplastia e revascularização do miocárdio). RESULTADOS: Após seguimento médio de 48 meses, 23 (36 por cento) pacientes sofreram eventos cardíacos. Não houve diferença clínica e angiográfica entre os pacientes que sofreram o evento e os que não o sofreram. Pela análise multivariada, a presença de dor precordial durante o teste ergométrico (risco relativo de 2,668 e p = 0,031) e a freqüência cardíaca no início da isquemia (risco relativo de 0,966 e p = 0,009) foram associadas a eventos cardíacos. CONCLUSÃO: Nessa população idosa, a presença de dor precordial durante o teste ergométrico e a freqüência cardíaca no início da isquemia foram associadas a eventos cardíacos. Essas variáveis podem ser úteis para avaliação do risco de pacientes com doença aterosclerótica coronariana estável.

ABSTRACT

BACKGROUND: The process of aortic degeneration associated with calcified aortic stenosis shares many similarities with coronary artery atherosclerosis. Inflammation and infection are involved in both diseases. Chlamydia pneumoniae has been identified in atherosclerotic plaques. However, the studies about the presence of C. pneumoniae in degenerative aortic stenotic valves are not conclusive. OBJECTIVE: We investigated whether an association exists between the density of C. pneumoniae and fibrosis or calcification in aortic stenosis. DESIGN: Autopsy and surgical specimens were divided into 3 groups: Normal, 11 normal autopsy valves Atherosclerosis, 10 autopsy valves from patients with systemic atherosclerosis and no aortic stenosis and Aortic stenosis, 14 surgical specimens of aortic valves replaced due to aortic stenosis. SETTING: Heart Institute (InCor), University of São Paulo Medical School. PATIENTS: Aortic valves from patients aged 52+/-16 years, 69+/-9 years, and 71+/-8 years. INTERVENTION: Specimens were evaluated by immunohistochemical technique (to detect C. pneumoniae antigens), in situ hybridization, and electron microscopy (to quantify the density of C. pneumoniae in the valves). MEASUREMENTS: The aortic stenosis group was analyzed according to 3 subregions: aortic stenosis-preserved, peripheral preserved regions; aortic stenosis-fibrosis, peri-calcified fibrotic tissue; and aortic stenosis-calcification, calcified nodules. RESULTS: The median values of C. pneumoniae antigens were 0.09, 0.30, 0.18, 1.33, and 3.3 in groups Normal, Atherosclerosis, Aortic stenosis-preserved, Aortic stenosis-fibrosis, and Aortic stenosis-calcification, respectively. The amount of C. pneumoniae was greater in the Atherosclerosis and Aortic stenosis-calcification groups than in the Normal group (P<0.05). C. pneumoniae was greater in the Aortic stenosis group in the calcified and fibrotic regions than in preserved region (P<0.05). CONCLUSION: An association was found between the higher density of C. pneumoniae and fibrosis/calcification in stenotic aortic valves.

ABSTRACT

OBJECTIVE: We investigated whether Chlamydia pneumoniae (CP) and Mycoplasma pneumoniae (MP) are present in aortic valve stenosis (AS). METHODS: Immunohistochemistry was utilized to identify CP antigens, in situ hybridization to identify MP DNA, and electron microscopy was used to evaluate the following three groups: Normal - 11 normal autopsy valves; Atherosclerosis - 10 autopsy valves from patients with systemic atherosclerosis and no AS; and AS - 14 surgical specimens of AS analyzed in 3 sub-regions: AS-Preserved - peripheral, preserved regions; AS-Fibrosis - peri-calcified fibrotic tissue; and AS-Calcification - calcified nodules. RESULTS: The positive area fraction of CP antigen median values were 0.09, 0.30, 0.18, 1.33, and 3.3 in groups Normal, Atherosclerosis, AS-Preserved, AS-Fibrosis, and AS-Calcification, respectively. CP density was significantly greater in Atherosclerosis and AS-Calcification than in Normal (P<0.05). Within the AS group, the amount of CP was greater in the Calcification and Fibrosis regions (P<0.05). MP-DNA positive area fraction (median values) were 0.12, 0.44, 0.07, 0.36, and 1.52 in groups Normal, Atherosclerosis, AS-Preserved, AS-Fibrosis, and AS-Calcification, respectively. The amount of MP-DNA was greater in AS-Calcification than in Normal (P<0.05). Within the AS group, MP-DNA was in larger quantity in the Calcification and Fibrosis regions (P<0.05). CONCLUSION: AS Calcified nodes present higher concentration of CP and MP suggesting that these bacteria may be associated with the development of calcification and inflammation. This adds novel similarities between AS and the atherosclerosis process, which may have infection mechanisms involved.

ABSTRACT

OBJETIVO: Investigar se chlamydia pneumoniae (CP) ou mycoplasma pneumoniae (MP) estão presentes na estenose da valva aórtica (EA). MÉTODOS: Imuno-histoquímica foi utilizada para identificar os antígenos de CP (Ag-CP), a hibridizacão in situ para identificar o DNA de MP, e microscopia eletrônica para avaliacão dos dois agentes, nos grupos: normal - 11 valvas normais de autópsia; aterosclerose - 10 valvas de pacientes com aterosclerose sistêmica de autópsia e sem EA; e EA - 14 espécimes cirúrgicos provenientes de pacientes com EA analisados em 3 sub-regiões: EA-preservada - regiões mais preservadas na periferia da valva; EA-fibrose - tecido fibrótico peri-calcificacão; e EA-calcificacão - nódulos calcificados. RESULTADOS: As medianas da fracão de área positiva para Ag-CP foram 0,09; 0,30; 0,18; 1,33; e 3,3 nos grupos acima descritos, respectivamente. A densidade de CP foi significativamente maior nos grupos aterosclerose e EA-calcificacão em relacão ao normal (p<0,05). Dentro do grupo EA, a quantidade de CP foi maior nas regiões de fibrose e calcificacão (p<0,05). As fracões de área positivas para MP-DNA (medianas) foram 0,12; 0,44; 0,07; 0,36; e 1,52 nos grupos acima descritos, respectivamente. A quantidade de MP-DNA foi maior na EA-calcificacão em relacão ao normal (p<0,05). Dentro do grupo EA, maior quantidade de MP-DNA foi encontrada nas regiões de calcificacão e fibrose (p<0,05). CONCLUSAO: Os nódulos de calcificacão da EA tinham maior concentracão de CP e MP sugerindo que essas bactérias possam estar associadas ao desenvolvimento de calcificacão e inflamacão, apontando novas semelhancas entre os processos de EA e aterosclerose, que podem ter mecanismos infecciosos envolvidos.

ABSTRACT

OBJECTIVE: To assess whether hormone replacement therapy with estrogens in association with progestogens in postmenopausal hypertensive women alters postprandial triglyceridemia and vascular reactivity. METHODS: A double-blind, placebo-controlled, crossover study was carried out with 15 postmenopausal women (age range: 50 to 70 years, mean = 61.6 +/- 6 years) randomly assigned to 2 weeks of placebo or oral ingestion of 0.625 mg of equine conjugated estrogens and 2.5 mg of medroxyprogesterone, fed a high-fat diet (897 calories; 50.1% fat). Vascular reactivity (VR - % of vessel diameter variation in the fasting period and 2 hours after meals) was measured by using the automated ultrasound method. Lipid profile and glycemia during the fasting period and 2 hours after a high-fat meal were measured. RESULTS: With placebo, vascular reactivity (VR) decreased from 3.20 +/- 17% during the fasting period to -2.1 +/- 30% 2 hours after the meal (P = 0.041). With the hormone replacement therapy, vascular reactivity decreased from 6.14 +/- 27% during the fasting period to - 0.05 +/- 18% 2 hours after the meal (P = NS). Postprandial triglyceridemia increased as follows: 35 +/- 25% with placebo; and 12 +/- 10% with hormone replacement therapy (P < 0.05). CONCLUSION: In postmenopausal hypertensive women, 2 weeks of hormone replacement with an association of estrogens and progestogens decreased hypertriglyceridemia after a high-fat meal, an effect that may reduce the endothelial dysfunction occurring in the postprandial period.

ABSTRACT

OBJETIVO: Avaliar se a terapia de reposição hormonal com estrogênios e progestogênios, em mulheres hipertensas na pós-menopausa, modifica a trigliceridemia e a reatividade vascular pós-prandial. MÉTODOS: Estudo controlado, duplo cego, cruzado contra placebo em 15 mulheres na pós-menopausa (idade de 50 a 70, média = 61,6 ± 6 anos), sorteadas para 2 semanas de placebo ou ingestão oral de 0,625 mg de estrogênios conjugados eqüinos e 2,5 mg de medroxiprogesterona e alimentadas com refeição rica em gorduras (897 calorias; 50,1 por cento de gorduras). Foi medida a reatividade vascular (RV - por cento de variação dos diâmetros do vaso entre o jejum e 2h após a alimentação), usando-se método ultra-sonográfico automatizado. Foram também determinados o perfil lipídico e a glicose, em jejum e 2h após a alimentação rica em gorduras. RESULTADOS: Com o placebo, a reatividade vascular (RV) diminuiu de 3,20 ± 17 por cento em jejum para -2,1 ± 30 por cento, 2h após a alimentação (p = 0,041), e com terapia de reposição hormonal, a reatividade vascular diminuiu de 6,14 ± 27 por cento em jejum para -0,05±18 por cento, 2h após a alimentação (p=NS). A trigliceridemia pós-prandial aumentou, 35 ± 25 por cento com o placebo, e 12 ± 10 por cento com a terapia de reposição hormonal (P < 0,05). CONCLUSAO: Em mulheres hipertensas, na pós-menopausa, 2 semanas de reposição hormonal com uma associação de estrogênios e progestogênios, diminuiu a hipertrigliceridemia após uma refeição com alto teor de gorduras, efeito que pode melhorar a disfunção endotelial existente no período pós-prandial.

ABSTRACT

OBJECTIVE: To assess the strategy of titration for prescribing an efficient dosage of propranolol to reduce myocardial ischemia in the elderly. METHODS: The study comprised 14 elderly men (73.6 +/- 5.3 years) with stable coronary heart disease documented on coronary cineangiography, ischemic response to exercise testing, and preserved left ventricular function. Titration was performed to identify the dosage of propranolol that would cause a 15% reduction in heart rate at the end of a 50 W load (corresponding to normal daily activities in the elderly) in weekly exercise tests. Synchronous scintigraphic study of the cardiac chambers was performed at rest and during exercise prior to and after propranolol use. RESULTS: The reductions in heart rate with the 50 W load and at rest were similar (21% vs 20%; P=0.5100). Propranolol improved the duration of exercise (12.2 +/- 2.0 min vs 13.1 +/- 1.8 min; P=0.0313) and abolished the changes in the ST segment induced by exercise in 8 (57%) patients. At rest, the ejection fraction was not modified by the beta-blocker. During maximum exercise, propranolol reduced the end-systolic volume index and increased ejection fraction. CONCLUSION: The strategy of using beta-blockers to reduce heart rate by 15% with a 50 W load is safe and beneficial in the elderly patient with myocardial ischemia and preserved ventricular function. The dose of beta-blocker used reduced myocardial ischemia and improved tolerance to exercise without hampering ventricular performance during maximum exercise.

ABSTRACT

OBJETIVO: Avaliar estratégia de titulação para prescrever uma dose de propranolol que seria eficiente em reduzir isquemia do miocárdio em idosos. MÉTODOS: Foram estudados 14 homens idosos (73,6 ± 5,3 anos), portadores de doença coronariana estável, documentada pela cinecoronariografia, com resposta isquêmica ao teste ergométrico e função ventricular esquerda preservada. O propranolol foi titulado a fim de atingir redução de 15 por cento na freqüência cardíaca, ao final da carga de 50 W (correspondente às atividades diárias normais de idosos), em testes ergométricos semanais e feito estudo cintilográfico sincronizado das câmaras cardíacas, em repouso e durante exercício, antes e após seu uso. RESULTADOS: As reduções da freqüência cardíaca na carga de 50 W e em repouso foram semelhantes (21 por cento vs 20 por cento; p=0,5100). O propranolol melhorou a duração do exercício (12,2 ± 2,0 min vs 13,1 ± 1,8 min; p=0,0313) e aboliu as alterações do segmento ST induzidas pelo exercício em 8 (57 por cento) pacientes. Em repouso, a fração de ejeção não foi modificada pelo betabloqueador. Durante o exercício máximo, o propranolol reduziu o índice de volume sistólico final e aumentou a fração de ejeção. CONCLUSAO: A estratégia de empregar betabloqueadores para reduzir a freqüência cardíaca em 15 por cento na carga de 50 W é segura e benéfica nos idosos com isquemia miocárdica e função ventricular preservada. A dose utilizada reduziu a isquemia miocárdica e melhorou a tolerância ao exercício, sem prejudicar o desempenho ventricular durante exercício máximo.

OBJECTIVE: To assess the relation between the evolution of cognitive performance and the prognosis of elderly patients after compensation of advanced heart failure. METHODS: Thirty-one patients older than 64 (68 +/- 7) years and admitted with New York Heart Association class IV heart failure and ejection fraction = 0.45 (0.38 +/- 0.06) were consecutively selected. They underwent cognitive tests (digit span, digit symbol, letter cancellation, trail making A and B) and the 6-minute walking test 4 days before (T1) and 6 weeks after (T2) hospital discharge, and their performances were compared using the t test. The prognostic value of the scores of the cognitive tests was analyzed with logistic regression, and the value of greatest accuracy of the tests was associated with the prognosis determined by the ROC curve. RESULTS: After 24.7 months, 17 (55%) patients had died. The performances in the 6-minute walking test and most cognitive tests improved between T1 and T2. The digit span score of the survivors ranged from 3.9 to 5.2 (P=0.003) and remained unaltered among those who died (4.1 to 3.9; P=0.496). An improvement < 0.75 points in the score was associated with mortality (relative risk of 8.1; P=0.011). CONCLUSION: In the elderly, after compensation of advanced heart failure, the lack of evolutionary improvement in cognitive performance was associated with a worse prognosis.
