Venous thromboembolism and the risk of subsequent symptomatic atherosclerosis.

BACKGROUND: Recently, we reported an association between asymptomatic carotid atherosclerosis and venous thromboembolism (VTE) of unknown origin. We hypothesized that patients with VTE of unknown origin would be at a higher risk of developing symptomatic atherosclerosis than patients with VTE induced by known risk factors. METHODS: To examine this hypothesis, we studied 1,919 consecutive patients followed prospectively after their first VTE episode. The primary outcome was non-fatal and fatal symptomatic atherosclerotic disease in patients with VTE of unknown origin as compared to those with secondary VTE. An independent committee assessed all study outcomes, and adjusted hazard ratios (HR) were calculated using the Cox's proportional hazards model. RESULTS: After a median follow-up of 48 and 51 months, respectively, at least one symptomatic atherosclerotic complication was detected in 160 of the 1,063 patients (15.1%) with VTE of unknown origin, and in 73 of the 856 (8.5%) with secondary VTE. After adjusting for age and other risk factors of atherosclerosis, the HR for symptomatic atherosclerotic complications in patients with VTE of unknown origin compared to those with secondary VTE was 1.6 (95% confidence intervals; CI: 1.2-2.0). When the analysis was restricted to patients without previous symptomatic atherosclerosis, the HR became 1.7 (95% CI: 1.1-2.4). CONCLUSIONS: Patients with VTE of unknown origin have a 60% higher risk of developing symptomatic atherosclerotic disease than do patients with secondary venous thrombosis.

Context-dependency of the relation between left ventricular mass and AGT gene variants.

In the European Project on Genes in Hypertension (EPOGH), we investigated in three populations to what extent in a family-based study, left ventricular mass (LVM) was associated with the C-532T and G-6A polymorphisms in the angiotensinogen (AGT) gene. We randomly recruited 221 nuclear families (384 parents and 440 offspring) in Cracow (Poland), Novosibirsk (Russia), and Mirano (Italy). Echocardiographic LVM was indexed to body surface area, adjusted for covariables, and subjected to multivariate analyses, using generalized estimating equations and quantitative transmission disequilibrium tests in a population-based and family-based approach, respectively. We found significant differences between the two Slavic centres and Mirano in left ventricular mass index (LVMI) (94.9 vs 80.4 g/m2), sodium excretion (229 vs 186 mmol/day), and the prevalence of the AGT -6A (55.7 vs 40.6%) and -532T (16.8 vs 9.4%) alleles. In population-based as well as in family-based analyses, we observed positive associations of LVMI and mean wall thickness (MWT) with the -532T allele in Slavic, but not in Italian male offspring. Furthermore, in Slavic male offspring, LVMI and MWT were significantly higher in carriers of the -532T/-6A haplotype than in those with the -532C/-6G or -532C/-6A allele combinations. In women, LVMI was neither associated with single AGT gene variants nor with the haplotypes (0.19 < P <0.98). In Slavic offspring carrying the AGT -532C/-6G or -532C/-6A haplotypes, LVMI significantly increased with higher sodium excretion (+3.5 g/m2/100 mmol; P=0.003), whereas such association was not present in -532T/-6A haplotype carriers (P-value for interaction 0.04). We found a positive association between LVMI and the AGT -532T allele due to increased MWT. This relation was observed in Slavic male offspring. It was therefore dependent on gender, age and ecogenetic context, and in addition it appeared to be modulated by the trophic effects of salt intake on LVM.

Triglycerides + high-density-lipoprotein-cholesterol dyslipidaemia, a coronary risk factor in elderly women: the CArdiovascular STudy in the ELderly.

BACKGROUND: The relationship between serum triglycerides (TG) level and the risk of coronary heart disease (CHD) mortality remains controversial. AIMS: To evaluate whether TG level is a risk factor for CHD in elderly people from general population, and to look for interactions between TG and other risk factors. METHODS: 3257 subjects aged >or= 65 years followed up for 12 years from the CArdiovascular STudy in the ELderly. Blood tests and anthropometric measurements were performed. Continuous items were divided into quintiles and, for each quintile, adjusted hazard ratio (HR) with 95% confidence interval (CI) for CHD mortality was derived by genders from Cox analysis. RESULTS: In women, the HR of being in the fifth rather than in the first quintile of TG was 2.45 (CI 1.48-3.51). In turn, high-density-lipoprotein cholesterol (HDL-C) inversely predicted CHD mortality; the HR of being in the first rather than in the fifth quintiles of HDL-C was 1.52 (CI 1.24-2.36). The risk of CHD mortality further increased up to 3.81 (CI 1.62-5.43) when high TG and low HDL-C were combined. No predictive role for either TG or HDL-C was detected in men. CONCLUSIONS: TG and HDL-C were independent predictors of CHD mortality in elderly women. The combination high TG + low HDL-C quadrupled the risk of CHD mortality in this gender only.

Total cholesterol and mortality in the elderly.

OBJECTIVE: To evaluate, at a population level, whether total cholesterol (TC) is a risk factor of mortality. To verify whether or not this is true for both genders. DESIGN: Population-based, long-lasting, prospective study. SETTING: Institutional epidemiology in primary care. SUBJECTS: A total of 3257 subjects aged 65-95 years, recruited from Italian general population. INTERVENTION: None. MAIN OUTCOME MEASURES: Total cholesterol was measured, analysed as a continuous variable and then divided into quintiles and re-analysed. For each quintile, the multivariate relative risk (RR) of mortality adjusted for confounders was calculated in both genders. Stratification of mortality risk by TC quintiles, body mass index and cigarette smoking was also performed in both genders. RESULTS: Total cholesterol levels directly predicted coronary mortality in men [RR being in the fifth rather than in the first quintile: 2.40 (1.40-4.14)] and any other mortality in women. It also inversely predicted miscellaneous mortality in both genders. This trend was more evident when low cholesterol was associated with malnutrition or smoking. CONCLUSIONS: High TC remains a strong risk factor for coronary mortality in elderly men. On the other hand, having a very low cholesterol level does not prolong survival in the elderly; on the contrary, low cholesterol predicts neoplastic mortality in women and any other noncardiovascular mortality in both genders.

Weak effect of hypertension and other classic risk factors in the elderly who have already paid their toll.

The aim of the CASTEL, a population-based (n=3282) prospective study which began 14 years ago, was to identify those items which had a prognostic impact in the elderly, and to evaluate whether the typical cardiovascular risk factors, particularly arterial hypertension, play a role after the age of 65 years. Initial screening, final follow-up and annual detection of mortality were performed. Mantel-Hanszel approach and multivariate Cox model were used for statistics. Cardiovascular mortality was 23.3% in normotensive, 23.3% in borderline, and 25% in the sustained hypertensive subjects (insignificant difference). In women, the incidence of stroke and coronary artery disease weakly depended on pulse pressure. Historical stroke and myocardial infarction predicted cardiovascular mortality in women; diabetes, uricaemia and high heart rate in men. In the very old, the predictors were less numerous, and blood pressure was not a predictor whatsoever; pulse blood pressure and murmurs at the neck were especially predictive in women, historical heart failure, proteinuria and tachycardia in men, historical stroke and myocardial infarction, pulmonary disease, left ventricular hypertrophy, diabetes and uricaemia in both genders. The elderly have a different cardiovascular risk pattern compared to younger people. Hypertension is not a predictor of coronary and stroke mortality. Prognosis depends on pulse pressure rather than on the label 'hypertension'. Hypercholesterolaemia is not a risk factor. This could simply indicate that elderly persons are the survivors in a population where significant mortality has already made its mark, eliminating those with the worst risk pattern. The two genders have a different risk profile due to sex-specific susceptibility to risk factors.

Pulse pressure and coronary mortality in elderly men and women from general population.

The aim of this work was to evaluate whether pulse pressure (PP) in elderly people is a better predictor of coronary mortality than systolic and diastolic blood pressure taken alone. For this aim, 3282 elderly subjects aged >or=65 years were studied in a population-based frame. Blood pressure was repeatedly measured and averaged; historical data, anthropometrics, blood tests and 14-year coronary mortality were recorded. Statistics included analysis of covariance, Cox analysis and bivariate vectorial analysis. Coronary mortality in women was predicted by PP (1.01 excess risk/mm Hg PP) and was significantly higher in the 3rd than in the 1st tertile of PP (relative risk 2.90); neither systolic nor diastolic pressure taken alone influenced mortality. When systolic and diastolic pressures were both entered into a Cox model, the former had a positive and the latter a negative effect on survival, confirming a prognostic role of PP. For any given level of systolic pressure, mortality was inversely associated with diastolic pressure. Finally, the mean vector representing both systolic and diastolic pressures of non-surviving women was characterised by higher systolic and lower diastolic components than in non-surviving. No significant trend of mortality in relation to either systolic blood pressure or PP was observed in men. In conclusion, the combination of systolic and diastolic pressure called PP is an independent predictor of coronary mortality in elderly females, and a better predictor than systolic or diastolic pressure alone.

Continuous subcutaneous insulin infusion (CSII) in the Veneto region: efficacy, acceptability and quality of life.

AIM: To study the effect of continuous subcutaneous insulin infusion (CSII) on metabolic control and well-being in patients with Type 1 diabetes. METHODS: Efficacy, safety and interference with everyday life associated with CSII were studied retrospectively in 138 diabetic patients from the Veneto region treated for 7.4 +/- 0.4 years. RESULTS: Glycosylated haemoglobin decreased during the first year of CSII from 9.3 +/- 0.2% to 7.9 +/- 0.1% (P < 0.0001), and then remained unchanged. Serious hypoglycaemia decreased from 0.31 +/- 0.07/year to 0.09 +/- 0.02/year (P < 0.003), as did ketoacidosis (from 0.41 +/- 0.12/year to 0.11 +/- 0.03/year, P < 0.013). During the first year of therapy daily insulin requirement decreased from 49 +/- 1 to 42 +/- 2 U/day (P < 0.0001) and did not change thereafter. The number of out-patient consultations and hospital admissions per year also decreased significantly. CSII was associated with a progressive increase of body weight (P < 0.05) and with 0.2 +/- 0.04 infections/patient per year at the infusion site. Infection was rated as mild in 72%, moderate in 18%, severe in 10%. Patients reported that CSII improved metabolic control (71%), sense of well-being (41%), and allowed more freedom (40%). Quality of life, assessed using the DQOL, after 7 years of CSII was rated as good by patients (score of 73.0 +/- 1.8 on a scale from 0 to 100). CONCLUSIONS: This retrospective analysis suggests that CSII improves metabolic control in Type 1 diabetic patients, reduces hypoglycaemic and ketoacidotic events, is well accepted, allows a good quality of life and decreases out-patient consultations and hospital admissions.

Predictors of stroke mortality in elderly people from the general population. The CArdiovascular STudy in the ELderly.

Stroke occurs particularly frequently in elderly people and, being more often disabling than fatal, entails a high social burden. The predictors of stroke mortality have been identified in 3282 subjects aged > or = 65 years, taking part in the CArdiovascular STudy in the ELderly (CASTEL), a population-based study performed in Northeast Italy. Historical and clinical data, blood tests and 14-year fatal events were recorded. Continuous items were divided into quintiles and, for each quintile, adjusted relative risk (RR) with 95% confidence intervals [CI] was derived from multivariate Cox analysis. Age, historical stroke (RR: 5.2; 95% CI: 3.18-8.6) and coronary artery disease (RR: 1.38; CI: 1.18-2.1), atrial fibrillation (RR: 2.40; CI: 1.42-4.0), arterial hypertension (RR: 1.33; CI: 1.15-1.76), systolic blood pressure > or = 163 mmHg (RR: 1.84; CI: 1.20-2.59), pulse pressure > or = 74 mmHg (RR: 1.50; CI: 1.13-2.40), cigarette smoking (RR: 1.60; CI: 1.03-2.47), electrocardiographic left ventricular hypertrophy (RR: 1.72; CI: 1.10-2.61), impaired glucose tolerance (IGT, RR: 1.83; CI: 1.10-3.0), uric acid (UA) > 0.38 mmol/l (RR: 1.61; CI: 1.14-2.10), serum potassium > or = 5 mEq/l (RR: 1.70; CI: 1.24-2.50) and serum sodium < or = 139 mEql/l (RR: 1.34; 1.10-2.10) increased the risk of stroke. In the CASTEL, stroke was the first cardiovascular cause of death. Some independent predictors usually unrelated to stroke mortality (namely pulse pressure, pre-diabetic IGT, UA and blood electrolytes disorders) have been identified.

Pulse pressure: an independent predictor of coronary and stroke mortality in elderly females from the general population.

The aim of this paper is to evaluate whether pulse pressure is an independent risk factor for coronary and stroke mortality in 3282 subjects (1281 males and 2001 females) aged +/- 65 years, taking part in the CArdiovascular STudy in the Elderly (CASTEL). After dividing subjects into tertiles of pulse pressure, adjusted relative risk (RR) and confidence intervals (CI) for 14-year coronary and stroke mortality was evaluated for each tertile. Among females, coronary mortality rate was 2.7% in the first tertile of pulse pressure, 4.7% in the second (RR 1.38, 95% CI [1.15-2.66]) and 6.2% in the third (RR 2, CI [1.20-3.51]). Stroke mortality was 3.6%, 4.1% (RR 1.23, CI [1.02-2.23]) and 8.3% (RR 2.27, CI [1.37-3.74]), respectively. This trend was recognizable in normotensive, borderline and sustained hypertensive women, where mortality increased with rising pulse pressure. No relationship was found between pulse pressure and mortality in males. In elderly women, pulse pressure was a good predictor of coronary and stroke mortality, even superior to the label of hypertension. No matter how any given pulse pressure level was obtained, it was more predictive of both coronary and cerebrovascular mortality than belonging to a normo- or hypertensive category.

Effect of blood pressure and physical activity on carotid artery intima-media thickness in stage 1 hypertensives and controls.

The aim of the study was to investigate whether hypertension and physical training induce parallel changes in the arterial wall. Ninety-seven never-treated stage 1 hypertensive patients (HT) (systolic blood pressure 140 to 159 mm Hg or diastolic blood pressure 90 to 99 mm Hg) aged 18 to 45 years taking part in the Hypertension and Ambulatory Recording Venetia Study and 27 normotensive volunteers (NT) aged 30 +/- 9 years were studied. Data on physical or sports activity were collected and scored, and target organ involvement was investigated by assessing microalbuminuria, echocardiography, and carotid ultrasound study. The carotid arteries were examined according to the Atherosclerosis Risk in Communities protocol. Mean (m-IMT) and maximal (M-IMT) carotid intima-media thickness were measured at end-diastole in the far wall common carotid artery, in the bulb and internal carotid artery, in the lateral and posterior projection, averaging the left and right sides. A comparable level of physical activity was present in HT patients and NT subjects. Twenty-four-hour blood pressure and blood lipid levels, as well as target organ damage, were similar in physically active and sedentary HT. The m-IMT of the common carotid was greater in sedentary HT than in sedentary NT, as well as in active than in sedentary NT. The m-IMT of the internal carotid artery was also greater in active HT than in active NT, as well as in active than in sedentary HT. In logistic regression, comparing the first and fourth quartile of m-IMT, scored physical activity was a predictor of m-IMT in the internal carotid artery. No statistical interaction was found between physical activity and hypertension, indicating that these two items have a cumulative effect and act independently of each other. Sedentary HT had significantly greater levels of M-IMT than sedentary NT in all sites but the bulbs; in the internal and common carotid arteries, HT exercisers had significantly greater M-IMT than NT exercisers. Therefore, physical activity appears to be an early independent predictor of carotid wall thickness. This factor should be taken into consideration in population-based studies aimed at investigating supraortic vessels as it can act as a confounder.

Cardiovascular mortality in non-insulin-dependent diabetes mellitus. A controlled study among 683 diabetics and 683 age- and sex-matched normal subjects.

Although non-insulin-dependent diabetes mellitus (NIDDM) is considered a major cause of death, the role of some independent risk factors in diabetic patients is under debate. In fact the prognosis of NIDDM diabetes varies considerably in relation to the individual risk pattern, and the different studies are not directly comparable because of differences in size, age and geography of the samples, and type of statistical analysis. The aim of the study is to identify the independent predictors of mortality in a cohort of subjects with NIDDM, and to verify whether the relative risk (RR) of cardiovascular mortality is different in comparison to that of coeval non-diabetic subjects from a general population. The study includes 683 patients with NIDDM from the Northern Italian town of Pordenone, followed up for 6 years and age- and sex-matched to 683 non-diabetic subjects from a Northern Italian general population. When the two cohorts were compared, NIDDM turned out to be a strong risk factor for cardiovascular mortality (RR: 2.67). Age, coronary artery disease (RR: 1.78), arterial hypertension (RR: 1.39), macro- (RR: 2.97) and microalbuminuria (RR: 2.01) were independent predictors of cardiovascular mortality in the diabetics. In conclusion, survival of diabetic patients is worse than that of non-diabetic coeval subjects. Only few items are able to predict cardiovascular mortality in the diabetics, namely age, hypertension, CAD, macro- and microalbuminuria.

Blood pressure and metabolic profile after surgical menopause: comparison with fertile and naturally-menopausal women.

In 1978 a random sample (367 men and 568 women aged 18-65 years) taken from the general population of a north-eastern Italian town was screened for cardiovascular risk; 16 years later, the women were invited to a second screening. Three groups were identified at the initial screening (fertile, naturally menopausal and surgically menopausal) and four in the longitudinal study (137 remained fertile during the whole study, 205 became naturally menopausal, 56 were ovariectomised and 127 were already going through the menopause). The protocol included a questionnaire, blood pressure (BP) measurement, and blood exams. Continuous variables were adjusted for confounders. Systolic BP, prevalence of hypertension, cholesterol, glycaemia and uricaemia were similar, whereas diastolic and triglycerides (TG) were lower in surgically-menopausal than in fertile women (P < 0.001). No significant difference in 16 years' variation from baseline was observed between the four groups, although women who remained fertile showed the smallest increases. In particular, neither systolic or diastolic BP increases differed between the women who were oophorectimised and those who remained fertile. 'Fertile status' was rejected from the logistic equation of incidence of hypertension, and 'age of menopause' was also rejected when this analysis was repeated in ovariectomised women. New coronary artery disease (angina pectoris or myocardial infarction) was observed in one ovariectomised woman, in three naturally menopausal, and in 13 already menopausal women which seemed to reflect the age trend. No new cases were observed in women who remained fertile. In conclusion, in Italian women surgical menopause, similarly to natural menopause, is devoid of any negative prognostic effect.

The 24-hour rhythm of blood pressure differs from that of leg hemodynamics in orthotopic heart transplant recipients.

BACKGROUND: This study was aimed at investigating whether a circadian rhythm of peripheral resistance exists in patients with orthotopic cardiac transplantation (OCT) and whether it parallels that of blood pressure (BP). METHODS: BP and leg flow and resistance (plethysmography) were monitored for 24 hours in 13 denervated OCT recipients and 13 control patients with native heart, matched for casual blood pressure. RESULTS: On the basis of BP trend, control patients showed a BP reduction during sleep, whereas OCT recipients did not. Leg resistance was significantly lower and leg flow significantly higher during sleep than during waking in all patients, and the extent of the nocturnal decrease was similar in the two categories. CONCLUSIONS: The decrease in leg resistance in patients confined to bed for 24 hours is caused by peripheral mechanisms and does not depend on the autonomic control of the heart. The nocturnal decline in BP depends, on the contrary, on cardiac control and is lost in patients with denervated heart.

High heart rate: a risk factor for cardiovascular death in elderly men.

OBJECTIVE: To examine the association between heart rate and 12-year incidence rates of total and cardiovascular death in a cohort of elderly subjects stratified by sex. SUBJECTS AND METHODS: The study was carried out in 763 white men and 1175 women aged 65 years or older who were participating in the Cardiovascular Study in the Elderly. Subjects were divided into quintiles of heart rate; the top quintile comprised those with a heart rate of greater than 80/min and the bottom quintile, those with a heart rate of less than 64/min. RESULTS: In the men, the number of deaths from cardiovascular causes was significantly increased in those in the top quintile of heart rate (crude relative risk, 1.55) but decreased in those in the bottom quintile (crude relative risk, 0.65). Similar relationships were found in the women, but the associations did not reach statistical significance (all-cause, P = .11; cardiovascular, P = .15). After adjustment for baseline age, body mass index, hypertension, diabetes mellitus, angina or previous myocardial infarction (coronary heart disease), regular medication, lipid levels, smoking, alcohol intake, forced expiratory volume in 1 second, and other confounders, the relative risk for cardiovascular death in the men was 1.38 (95% confidence interval, 0.94-2.03) for the subjects in the top quintile of heart rate and 0.82 (95% confidence interval, 0.52-1.28) for those in the bottom quintile. In the Cox analysis, predictors of time to cardiovascular death were heart rate (P < .001), age (P < .001), coronary heart disease (P < .001), clinical heart failure (P = .001), diabetes mellitus (P = .001), hypertension (P = .02), and triglyceride levels (P = .04), whereas total (P = .20) and high-density lipoprotein-cholesterol (P = .21) levels and smoking (P = .74) were found to be nonsignificant by the model. The heart rate-cardiovascular death association held true when subjects who died in 2 years after enrollment were excluded (P = .008). CONCLUSIONS: An elevated heart rate may be a strong predictor of cardiovascular death in elderly men. Conversely, a low heart rate is related to a better outcome in these subjects.

Antihypertensive drugs in very old people: a subgroup meta-analysis of randomised controlled trials. INDANA Group.

BACKGROUND: Beneficial clinical effects of treatment with antihypertensive drugs have been shown in middle-aged patients and in those hypertensive patients over 60 years old, but whether treatment is beneficial in patients over 80 years old is not known. METHODS: We collected data from all participants aged 80 years and over in randomised controlled trials of antihypertensive drugs through direct contact with study investigators. Our primary outcome was fatal and non-fatal stroke. Secondary outcomes were death from all causes, cardiovascular death, fatal and non-fatal major coronary and cardiovascular events, and heart failure. FINDINGS: There were 57 strokes and 34 deaths among 874 actively treated patients, compared with 77 strokes and 28 stroke deaths among 796 controls, representing 1 non-fatal stroke prevented for about 100 patients treated each year. The meta-analysis of data from 1670 participants aged 80 years or older suggested that treatment prevented 34% (95% CI 8-52) of strokes. Rates of major cardiovascular events and heart failure were significantly decreased, by 22% and 39%, respectively. However, there was no treatment benefit for cardiovascular death, and a non-significant 6% (-5 to 18) relative excess of death from all causes. INTERPRETATIONS: The inconclusive findings for mortality contrast with the benefit of treatment for non-fatal events. Results of a large-scale specific trial are needed for definite conclusion that antihypertensive treatment is beneficial in very elderly hypertensive patients. Meanwhile, an age threshold beyond which hypertension should not be treated cannot be justified.

24-hour leg and forearm haemodynamics in transected spinal cord subjects.

OBJECTIVE: A circadian rhythm of blood pressure has been demonstrated both in subjects who are physically active during the day and in those confined to bed. The study of the circadian rhythm of arterial flow and peripheral resistance, on the other hand, is limited to pioneer experiments. This paper is aimed at demonstrating that leg peripheral resistance has circadian fluctuations which are modulated by spinal neural traffic. METHODS: Eleven normal (able-bodied) human subjects and 11 patients with spinal transection due to spinal cord injury (SCI) were studied. They were confined to bed for 24 h. Blood pressure and heart rate were monitored every 15 min with an automatic device and leg flow with an automatic strain-gauge plethysmograph synchronised to the pressurometer. Peripheral resistance was calculated at the same intervals. RESULTS: In able-bodied subjects leg resistance was significantly higher during waking hours (when the sympathetic system is more activated) than during sleep, while in subjects with spinal cord injury no difference was detected between day-time and night-time. CONCLUSIONS: The circadian rhythm is controlled by adrenergic fibres transmitted via the spinal cord.

Predictors of cancer mortality in elderly subjects.

Cancer mortality was analysed in 3282 elderly subjects aged > or =65 years from 2 cohorts of general population having different life-style patterns. They took part in the CASTEL (CArdiovascular STudy in the ELderly), a 12-year lasting prospective Italian study. The aim of the present analysis was to identify the items able to influence cancer mortality. A biochemical profile and a questionnaire on lifestyle were collected. Continuous items were averaged and compared with analysis of variance, frequencies with the Pearson's chi2 test. Mortality was recorded yearly for 12 years from the Registrar's Office and causes of death double-checked by consulting medical case sheets and family doctors' files. The influence of items on mortality was evaluated with the Cox multivariate analysis. Relative risk (RR) of each item was adjusted for confounders. Age, gender, tobacco smoking, the presence of respiratory symptoms, low body mass index in males, serum alanine transaminase (ALT) and alkaline phosphatase (ALP), as well as the town of residence, were powerful predictors of cancer mortality. In the entire population, 12-year overall mortality was 49.4%, cardiovascular 22.8%, and neoplastic 11%; the latter was higher in males than in females (15.7% vs. 7.9%, p < 0.00001). In subjects with respiratory symptoms neoplastic mortality was 11.6% (RR: 1.47) vs. 9.7% in those without symptoms (p < 0.01). Subjects with very low cholesterol (< or = 178 mg/dl), those with high uric acid (> or =8.7 mg/ dl) and males with low body mass index (< or =22.7 kg/ m2) has an increased risk of cancer mortality. RR of cancer mortality increased with increasing ALT or ALP. It was approximately 1 in those having ALT and ALP between 9 and 41.2 U/I, 1.41 in those exceeding this latter level and < 1 in those below 9 U/I. RR of ALP had a similar trend, the best protective cut-off value being < 106 and the worst one > 177 U/I. When both serum enzymes were simultaneously raised, RR of cancer mortality increased to 2.84.

Effects of a traditional lifestyle on the cardiovascular risk profile: the Amondava population of the Brazilian Amazon. Comparison with matched African, Italian and Polish populations.

OBJECTIVE: To determine the relationships between lifestyle and cardiovascular risk factors among the Brazilian Amondava, one of the world's most isolated populations. DESIGN: Cross-sectional, population-based study. Four age- and sex-matched samples from Brazil Africa, Italy and Poland, representing different levels of modernization, were compared. Body weight, height, blood pressure, serum cholesterol and glycaemia were measured, and a standard questionnaire administered. Data concerning dietary habits and physical activity were collected. A personal socio-economic score was calculated, on the basis of type of economy, level of formal education, type of occupation, type of habitat, availability of piped water and electricity, main source of income, housing conditions, availability of radio, television or personal computer, knowledge of a second language, and organized health facilities. SETTING: Primary epidemiological screening, at an institution. RESULTS: Among the Amondava blood pressure was always <140/90 mm Hg, it did not increase with age and was not correlated with any other variable; 46.6% of subjects had systolic blood pressure <100 mm Hg. Blood pressure among the Amondava (109.6+/-11.1/69.5+/-6.4 mm Hg) was on average lower (P<0.0001) than in all other samples. Among the Amondava, the concentration of total cholesterol was always <200 mg/dl, i.e. similar to that of Africans whose diet included large amounts of vegetable foodstuffs; 90% had glycaemia (<80 mg/dl), and their mean value was the lowest (55.1+/-14.9 mg/dl) of all the groups. CONCLUSIONS: In addition to a possible genetic predisposition not analysed in this study, a traditional lifestyle (no contact with civilization, diet based on complex carbohydrates and vegetables, high energy expenditure) may protect against the development of hypertension, hypercholesterolaemia, and diabetes.
