Summary The mortality status of all individuals in Norway with the onset of Type 1 (insulin-dependent) diabetes mellitus from 1973 through 1982 and age at onset below 15 years was determined as of 1 July 1988. Of the 1908 cases included in the follow-up, 20 had died (15 males and 5 females) and 10 had emigrated. A two-fold increased risk for early mortality was exhibited among this cohort. Life-table analyses did not find sex or age at onset of Type 1 diabetes to be statistically significant predictors of survival when controlling for diabetes duration. A review of death certificates revealed that accidents and suicides accounted for 40% of the deaths in the total cohort and that this cause of death occured only among male subjects. Acute diabetes related complications were the underlying causes of death for 35% of the subjects. Diabetic renal disease and death by cardiovascular disease were not documented in this young cohort with a maximum age of 30 years and maximum diabetes duration of 15.5 years. This is the first mortality report of a population-based registered cohort of Type 1 diabetic patients for Norway. While still being at increased risk for premature death, this cohort appears to be at decreased risk of early death when compared to a cohort of young diabetic patients from Oslo, Norway diagnosed in 1925–1955, suggesting improvements in the survival of individuals with Type 1 diabetes in Norway. 相似文献

AimsThe purpose of this study is to evaluate the effect of glycemic regulation, dyslipidemia, and renal dysfunction on mortality (all-cause and cardiovascular) and ischemic heart disease (IHD) in a long-term follow-up of a population-based cohort of Danish type 1 diabetic patients with at least 20 years of diabetes.MethodsA population-based cohort of type 1 diabetic patients was identified as of July 1, 1973 (n=727). In 1993 to 1996, the cohort was reassessed and baseline data were collected from blood and urine samples in 389 patients. Mean (glycemic regulation and lipids) and highest values (creatinine and albuminuria) of the baseline period were used to predict mortality and IHD between baseline and 2006. Data of mortality and morbidity were provided by the Danish Civil Registration System, the Danish Causes of Death Registry, and the Danish National Patient Registry.ResultsAt the follow-up in 2006, 256 patients (65.8%) were still alive. In a statistical model adjusted for age, sex and duration of diabetes, the following parameters were related to all-cause mortality and cardiovascular mortality: glycemic regulation, triglycerides, low-density lipoprotein cholesterol, high-density lipoprotein cholesterol (inversely), total cholesterol, creatinine, and macroalbuminuria. Furthermore, all markers except macroalbuminuria were associated with IHD. Microalbuminuria at baseline was not related to any of the endpoints.ConclusionsGlycemic regulation, dyslipidemia, and renal dysfunction were all related to mortality and IHD in a 13-year follow-up of long-term Danish type 1 diabetic patients. These results underscore the better outcome for tightly regulated type 1 diabetic patients, even in long-term survivors. 相似文献

By January 1990, over a period of 14 years, the Diabetic Clinic at Yekatit 12 Hospital, Addis Ababa had registered 1699 diabetic patients, of whom 204 were first diagnosed in or before 1969. Of these, 68 are known to have died after 11 to 36 years of diabetes (29% in renal failure), and 69 have been lost to follow-up for 3 or more years. Of the 121 who had been diabetic at least 20 years when last seen, 67 are attending, 18 are lost to follow-up, and 36 have died. Of these 121, 36.4% were known to have neuropathy, 29.8% nephropathy, and 45.5% retinopathy. Only 7 (5.8%) were Type 1 patients compared with 18.8% of the whole diabetic clinic, and most were obese Type 2 diabetic patients from Addis Ababa itself. Most of the 67 still attending after 20 to 34 years of diabetes are independent and fully employed, suggesting that the prognosis of diabetes may not be as dismal as has been generally reported from African countries. However, the survivors were mainly economically better-off Type 2 diabetic patients from the capital. 相似文献

AIMS: Type 2 diabetes mellitus and its complications are common among Polynesians in New Zealand. This study investigated the mortality from diabetes among indigenous Maori and recent migrants from the South Pacific. METHODS: Death certificates and other reports were collected to enumerate those who had died in an across-community cohort study of 765 diabetic patients aged 40-79 years in 1991. Five year mortality status was ascertained in 99.7% and death certificates were obtained from 129 (88%) of the 146 who had died. Diabetes was missed from 36% of death certificates. RESULTS: Compared to Europeans with Type 2 diabetes, Maori with Type 2 diabetes were 2.66 (1.63-4.35) fold as likely to die from diabetes-related conditions, including a 13.1 (3.7-46.4) fold greater risk of death from nephropathy. Pacific Islands Polynesians with Type 2 diabetes had a similar mortality to Europeans with Type 2 diabetes (hazards ratio 1.06 (0.68-1.65)). After 6 years, 10.7 (2.2-19.3)% more Maori had died than Pacific Islands Polynesians. CONCLUSIONS: Maori with Type 2 diabetes are dying from diabetic complications, particularly nephropathy, at an alarming rate. The magnitude of the difference between Maori and Pacific Islands Polynesians suggests environmental rather than inherited factors are involved and these need further investigation. 相似文献

PURPOSE: In the present study, our objective was to determine the epidemiological risk factors for the development of diabetic macular edema, especially attendant on renal diabetic lesion (microalbuminuria or overt nephropathy) in 112 Type I diabetic patients after 15 years. METHODS: This is a 15-year follow-up study of a cohort of 112 consecutive Type I (insulin-dependent) diabetes mellitus patients without diabetic retinopathy or nephropathy who were enrolled in 1990. We studied the incidence of diabetic macular edema and its risk factors. The epidemiological risk factors included in the study were as follows: gender, diabetes duration, glycated hemoglobin (HbA1c) levels, arterial hypertension, macroangiopathy, triglyceride levels, fractions of cholesterol [high-density lipoprotein cholesterol and low-density lipoprotein (LDL) cholesterol], and cigarette smoking. RESULTS: The incidence of diabetic macular edema after 15 years was as follows: the focal form of diabetic macular edema was present in 13 (11.6%) patients and the diffuse form of macular edema was present in 10 (8.9%) patients, among 23 (20.5%) patients. The following factors were significant in the development of diabetic macular edema: high levels of LDL-cholesterol (P=.013), high levels (>7.5%) of HbA1c (P=.021), the presence of macroangiopathy (P=.022), the severity of diabetic retinopathy (P=.029), the presence of arterial hypertension (P=.037), and the presence of overt nephropathy (P=.047). Microalbuminuria was not significant in logistic regression (P=.587), and cigarette smoking was not significant (P=.976). The relationship between diabetic macular edema and duration of diabetes presented two peaks of incidence: first in patients with 15-20 years' duration of diabetes mellitus, and second in patients with >35 years' duration. CONCLUSIONS: In summary, our data suggest that better control of glycemia, LDL-cholesterol levels, and blood pressure in Type I diabetes mellitus patients may be beneficial in reducing the incidence of diabetic macular edema. Finally, our data validate the current guidelines for ophthalmologic care for the detection of diabetic macular edema over the long-term course of diabetes. 相似文献

Sixty-four insulin-dependent (Type 1) diabetic patients (IDDM) in Soweto, South Africa were followed over a 10-year period. Patients were assessed in 1982 and again in 1992. There were 10 deaths (16%), half of which were due to renal failure. Ketoacidosis, hypoglycaemia, and sepsis accounted for the rest. At the 10-year follow-up mean age (± SD) was 32.4 ± 5.0 years and diabetes duration 13.6 ± 2.6 years. Retinopathy affected 52%, peripheral neuropathy 42%, and nephropathy 28% (all significantly increased from the 1982 assessment). Microalbuminuria and autonomic neuropathy were also common. Serum cholesterol was over 6.5 mmol I?1 in 19%, hypertension affected 22%, and 28% were cigarette smokers; though no patient had evidence of macroangiopathy. We conclude that IDDM in South Africa is associated with excess mortality, a significant proportion of which is related to nephropathy. Diabetes of long duration is now not uncommon in South Africa, and although diabetic complications frequently occur, most patients have good life quality and freedom from large vessel disease. 相似文献

BACKGROUND AND AIMS: An excess of long-term mortality in type 2 diabetes is mainly due to cardiac diseases, predicted by diabetes-related conditions; less is known about early death from clinical diagnosis. The aim of this study was to evaluate pattern and predictors of mortality after a 4.5 year follow-up in a cohort of type 2 diabetic patients, according to diabetes duration. METHODS AND RESULTS: A mortality follow-up was carried out in 1200 patients with < or = 5 years diabetes duration and 2692 patients with >5 (median 2 and 15) years diabetes duration in 1995. Four-year survival was 92.0% and 83.7%, respectively; most deaths are due to cardiovascular diseases (36% and 41%, respectively). The duration of diabetes is no longer a significant predictor of death after adjustments for age, HbA1c and chronic complications (which are all significantly higher in patients who have had diabetes for longer time). In a Cox proportional hazard model, best predictors of death are nephropathy, insulin therapy and pre-existent co-morbidity in both groups. Nephropathy is significantly associated with cardiovascular deaths in the younger cohort. CONCLUSION: Clinical nephropathy is a significant predictor of early and late mortality from clinical diagnosis, above all cardiovascular deaths, indicating that an aggressive approach should be adopted for prevention or treatment of renal impairment right from the clinical onset of diabetes. 相似文献

OBJECTIVES: Little is known about the long-term outcome and mortality patterns in systemic lupus erythematosus (SLE) in sub-Saharan Africa. We undertook a retrospective study of SLE in mainly black, unemployed patients, seen at a tertiary institution in Soweto, South Africa, to determine the causes and predictors of death. METHODS: Demographic, clinical and laboratory data and outcome were extracted from the case records of patients attending the Lupus Clinic at Chris Hani Baragwanath Hospital. RESULTS: Of the 270 case records with a diagnosis of SLE, 226 met the American College of Rheumatology classification criteria for SLE. The female to male ratio was 18 : 1. The mean (s.d.) age at presentation was 34 (12.5) yrs. Arthritis, nephritis and neuropsychiatric disease had a cumulative frequency of 70.4, 43.8 and 15.9% of patients, respectively. During the course of a mean follow-up period of 54.9 months, 193 (85.3%) and 89 (39.3%) patients were treated with oral corticosteroids and immunosuppressive agents, respectively. There were 55 (24.5%) known deaths and 64 (28.6%) patients were lost to follow-up. The estimated 5 yr survival rates were between 57 and 72%, depending on whether the group of patients lost to follow-up was classified in the analysis as either alive or dead. Infection (32.7%) was the commonest cause of death followed by renal failure (16.4%). Univariate analysis revealed that nephritis, neuropsychiatric disease and hypocomplementaemia were associated with an increased mortality, but multivariate analysis showed nephritis as the only significant predictor of mortality. CONCLUSION: Our findings suggest that SLE in indigent South Africans not only carries a poorer prognosis but also the main cause of death, infection and renal failure differ from those reported recently in industrialized Western countries. Nephritis is common in our patients and is the only independent predictor of poor outcome. 相似文献

AIMS: (i) To compare mortality rates in a cohort of Type 2 diabetic patients with those of the general population; (ii) to assess the prognostic role of pre-existing chronic conditions; (iii) to evaluate the impact of different severity of renal damage on mortality. METHODS: All 3892 patients with Type 2 diabetes attending our Diabetic Clinic during 1995 and alive on 1 January 1996 were identified and followed for 4.5 years. Information on vital status (100% complete) and causes of death (98.5% complete) for 599 deceased subjects was derived from death certificates. RESULTS: In comparison with the general population, standardized mortality ratios (x 100) were: 125 (95% confidence interval 104-148) in patients aged < 75 and 85 (75-95) in patients > or = 75 years. Cardiovascular diseases and diabetes were responsible for most of the excess deaths. In a Cox-proportional hazard model, renal damage was a powerful predictor of death (hazard ratio = 2.39; 95% confidence intervals = 2.00-2.85). The severity of renal damage was associated with increasing hazard ratios for death from all-cause mortality and from specific causes (especially coronary artery disease, other cardiovascular causes and diabetes) after multiple adjustments. Other significant predictors of death were: greater age, glycated haemoglobin, smoking, lower body mass index, pre-existing coronary and peripheral artery disease and known co-morbidity (cirrhosis and cancer). CONCLUSIONS: Renal damage of any severity is significantly associated with subsequent mortality from all causes and from cardiovascular diseases. These associations are not confounded by pre-existing co-morbidity or coronary diseases. 相似文献

An audit of hypoglycaemic admissions among diabetic patients to Baragwanath Hospital, Soweto, South Africa was carried out prospectively during a recent 5-month period. A total of 51 episodes of biochemically confirmed hypoglycaemia (blood glucose < 2.2 mmol I?1 with coma or pre-coma, and requiring intravenous glucose) were observed in 43 patients. There was a wide range of ages (22–88 years) and an excess of males (27M:16F). Fourteen (33%) cases were associated with sulphonylurea (gliclazide) treatment. Doses of insulin or sulphonylureas were not excessive. The major cause precipitating the event was a missed meal (36 %), though alcohol (22 %), gastrointestinal upset (20%), and inappropriate treatment (18%) were also important contributory factors. Following recovery from the event, doses of drugs or insulin were frequently reduced, and three patients were successfully taken off insulin, and six off gliclazide. There was no mortality in this series, and no obvious long-term morbidity. We conclude that severe hypoglycaemia is a frequent and important acute diabetic complication in Soweto. Patient education and care in prescribing for Type 2 diabetic patients may help reduce its occurrence and severity. 相似文献

AIMS: To study the glucose disappearance rate and fasting blood glucose as predictors of Type 2 diabetes in a 22.5-year prospective follow-up of 1947 healthy non-diabetic men. SUBJECTS AND METHODS: Of a cohort of 2014 Caucasian men, the 1947 who had both fasting blood glucose < 110 mg/dl and an intravenous glucose tolerance test were included. A number of other physiological parameters were also determined at baseline. Multivariate Cox regression analyses were used to investigate the possible significance of the glucose disappearance rate and fasting blood glucose as predictors of Type 2 diabetes. RESULTS: After 22.5 years' follow-up, 143 cases of Type 2 diabetes had developed. Glucose disappearance rate and fasting blood glucose were moderately correlated (r = -0.32). Men in the lowest quartile of glucose disappearance rate and highest quartile of fasting blood glucose had markedly higher diabetes rates than all other men (P < 0.0001). After adjusting for each other, age, diabetes heredity, body mass index, physical fitness, triglycerides, cholesterol and blood pressure (Cox model), both glucose disappearance rate and fasting blood glucose remained major predictors of diabetes CONCLUSIONS: Glucose disappearance rate and fasting blood glucose are, in spite of low intercorrelation, major long-term predictors of Type 2 diabetes in healthy non-diabetic Caucasian men. 相似文献

Objectives To describe and analyze the clinical characteristics and outcomes for all patients with diabetes who were hospitalized with laboratory‐confirmed A(H1N1)pdm09 infections in Spain during 2009. Methods Observational retrospective study using data collected by the Spanish National Hospital Discharge Database. We selected all admissions with diagnosis ICD‐9‐CM code 488·1 [A(H1N1)pdm09]. Discharges were grouped as follows: no diabetes, Type1 and Type 2 diabetes. Underlying medical conditions and risk factors included all those that constitute an indication for annual influenza vaccination, pregnancy, and obesity. The outcome variables analyzed were in‐hospital case fatality risk, length of hospital stay, and costs. Results The total number of persons hospitalized with A(H1N1)pdm09 was 11 499. Of those, 97 suffered Type 1 and 936 Type 2, giving an overall prevalence of diabetes of 9%. The most common underlying medical condition among Type 2 subjects was obesity (26·8%), and for Type 1 renal disease (10·3%). In‐hospital mortality was 2·1% among Type 1 patients, 3·8% among Type 2 patients, and 2·3% among non‐diabetics; after multivariate analysis, diabetes was not a factor independently associated with dying during hospitalization for A(H1N1)pdm09. Independent factors increasing the risk of death among diabetic patients included age (OR 1·03; 95% CI1·01–1·05), hematological disorders (OR 3·49; 95% CI, 1·46–8·37), and obesity (OR 1·88; 95% CI1·07–3·92). Conclusions Among individuals hospitalized in Spain with A(H1N1)pdm09 infections, the age‐specific prevalence of diabetes was higher than the general population in most age groups. The results of multivariate analysis suggest that possibly concomitant conditions such as obesity increase the risk of dying from the infection, but not diabetes itself. 相似文献

AIMS: Diabetic nephropathy is an uncommon cause of end-stage renal disease in Iceland in contrast to most industrialized countries. The aim of this study was to examine the incidence of diabetic nephropathy in Iceland. METHODS: All patients diagnosed with Type 1 diabetes in Iceland before 1992 were studied retrospectively. Patients diagnosed before age 30, who were insulin dependent from the onset, were defined as having Type 1 diabetes. Diabetic nephropathy was defined as persistent proteinuria measured with a dipstick test (Albustix) on three consecutive clinic visits at least 2 months apart. Patients were followed to the end of year 1998, to their last recorded outpatient visit, or until death. The cumulative incidence of diabetic nephropathy was calculated with the Kaplan-Meier method and presented according to the duration of diabetes divided into 5-year intervals. RESULTS: A total of 343 patients with Type 1 diabetes were identified. The mean follow-up period was 20.2 +/- 11.4 (mean +/- sd) years. Only 9.3% of patients were lost to follow-up. Sixty-five patients developed diabetic nephropathy. The cumulative incidence was 22.6% at 20 years and levelled off at 40.3% after approximately 35 years of diabetes duration. No significant changes in cumulative incidence were observed over time. Mean glycated haemoglobin was 8.4% in patients with proteinuria and 7.8% in a group of patients without proteinuria that was matched for age, gender and duration of diabetes (P = 0.04). CONCLUSIONS: The cumulative incidence of diabetic nephropathy in Iceland is comparable with previously reported cumulative incidence rates and has remained unchanged. Glycaemic control was significantly better in patients without proteinuria. 相似文献

AIMS/HYPOTHESIS: Although ischaemic heart disease is the predominant cause of mortality in older people with diabetes, age-specific mortality rates have not been published for patients with Type 1 diabetes. The Diabetes UK cohort, essentially one of patients with Type 1 diabetes, now has sufficient follow-up to report all heart disease, and specifically ischaemic heart disease, mortality rates by age. METHODS: A cohort of 23,751 patients with insulin-treated diabetes, diagnosed under the age of 30 years and from throughout the United Kingdom, was identified during the period 1972 to 1993 and followed for mortality until December 2000. Age- and sex-specific heart disease mortality rates and standardised mortality ratios were calculated. RESULTS: There were 1437 deaths during the follow-up, 536 from cardiovascular disease, and of those, 369 from ischaemic heart disease. At all ages the ischaemic heart disease mortality rates in the cohort were higher than in the general population. Mortality rates within the cohort were similar for men and women under the age of 40. The standardised mortality ratios were higher in women than men at all ages, and in women were 44.8 (95%CI 20.5-85.0) at ages 20-29 and 41.6 (26.7-61.9) at ages 30-39. CONCLUSIONS/INTERPRETATION: The risk of mortality from ischaemic heart disease is exceptionally high in young adult women with Type 1 diabetes, with rates similar to those in men with Type 1 diabetes under the age of 40. These observations emphasise the need to identify and treat coronary risk factors in these young patients. 相似文献

Summary The 497 members of the London Cohort of the WHO Multinational Study of Vascular Disease in Diabetics have been followed for mortality from 1975 to 1987. During this period 92 patients died. The most common cause of death was myocardial infarction: 36 (39.1%) deaths, heart disease was responsible for 51.1% of deaths and all cardiovascular disease for 55.4%. Neoplastic disease accounted for 25% of the deaths and diabetic nephropathy for 5.4%. Age-standardised mortality rates were higher in men than in women in both Type 1 (insulin-dependent) diabetes and Type 2 (non-insulin-dependent) diabetes. Standardised mortality ratios for the first and second five year follow-up periods were higher for men than for women in Type 2 diabetes but were higher for women than men in Type 1. The results suggest that the female survival advantage seen in the general population may persist in Type 2 but not in Type 1 diabetes. 相似文献

OBJECTIVE: To describe mortality, mode of death, risk indicators for death and symptoms of angina pectoris among survivors during 5 years after coronary artery bypass grafting (CABG) among patients with and without a history of diabetes mellitus. METHODS: All patients in western Sweden who underwent CABG without concomitant valve surgery and who had no previous CABG between June 1988 and June 1991 were entered prospectively in this study. After 5 years, information on deaths that had occurred was obtained for the analysis. RESULTS: In all, 1998 patients were included in the analysis; 242 (12%) had a history of diabetes. Among the non-diabetic patients, 5-year mortality was 12.5%; the corresponding relative risk for diabetic patients was 2.1 (95% confidence interval 1.6 to 2.9). A history of diabetes was an independent risk indicator of death; there was no significant interaction between any other risk indicator and diabetes. Independent risk indicators for death among diabetic patients were: current smoking, renal dysfunction and left ventricular ejection fraction < 0.40. Compared with non-diabetic patients, those with diabetes more frequently died in hospital, died a cardiac death, or had death associated with the development of acute myocardial infarction and with symptoms of congestive heart failure. Among survivors, diabetic patients tended to have more angina pectoris 5 years after CABG than did those without diabetes. CONCLUSION: During a period of 5 years after CABG, diabetic patients had a mortality twice that of non-diabetic patients. The increased risk included death in hospital, cardiac death and death associated with development of acute myocardial infarction and with symptoms of congestive heart failure. 相似文献

Admission blood glucose level as risk indicator of death after myocardial infarction in patients with and without diabetes mellitus 总被引:26,自引:0,他引:26

BACKGROUND: High admission blood glucose levels after acute myocardial infarction (AMI) are common and associated with an increased risk of death in subjects with and without known diabetes. Recent data indicate a high prevalence of abnormal glucose metabolism in patients with unknown diabetes at the time of AMI. We investigated the predictive value of admission blood glucose levels after AMI for long-term prognosis in patients with and without previously diagnosed diabetes mellitus, particularly in those with unknown diabetes but with blood glucose levels in the diabetic range. METHODS: In a retrospective study with prospective follow-up, 846 patients (737 without and 109 with known diabetes) were eligible for follow-up during a median of 50 months (range, 0-93 months). RESULTS: During follow-up, 208 nondiabetic patients (28.2%) and 47 diabetic patients (43.1%) died (P =.002). An increase of 18 mg/dL (1 mmol/L) in glucose level was associated with a 4% increase of mortality risk in nondiabetic patients and 5% in diabetic patients (both P<.05). Of the 737 previously nondiabetic subjects, 101 had admission blood glucose levels of 200 mg/dL (11.1 mmol/L) or more, and mortality in these patients was comparable to that in patients who had established diabetes (42.6% vs 43.1%). CONCLUSIONS: Admission blood glucose level after AMI is an independent predictor of long-term mortality in patients with and without known diabetes. Subjects with unknown diabetes and admission glucose levels of 200 mg/dL (11.1 mmol/L) or more after AMI have mortality rates comparable to those of subjects with established diabetes. Admission blood glucose level may serve to identify subjects at high long-term mortality risk, in particular among those with unknown diabetes. 相似文献

AIMS: To study patterns and predictors of early mortality in individuals with a new diagnosis of Type 2 diabetes, compared with a local age- and sex-matched comparison cohort. METHODS: A total of 736 individuals diagnosed with Type 2 diabetes between 1 May 1996 and 30 June 1998 and non-diabetic age- and sex-matched control subjects were studied. Follow-up was 5.25 years. Age- and gender-specific all-cause mortality odds ratios were calculated for the diabetic cohort compared with the non-diabetic comparator group. Mortality odds ratios were ascertained using conditional logistic regression. RESULTS: There were 147 deaths in the diabetic cohort [cardiovascular (42.2%), cancer (21.1%)]. Compared with the non-diabetic cohort, mortality odds more than doubled [odds ratio (OR) 2.47; 95% confidence interval (CI) 1.74, 3.49]. These increased odds were present in all age bands (including those aged > 75 years at diagnosis) for both cardiovascular and non-cardiovascular causes. In women, a new diagnosis of Type 2 diabetes was associated with a sevenfold increase in mortality odds in those aged 60-74 years (OR 7.00; 95% CI 2.09, 23.47). CONCLUSIONS: Type 2 diabetes is associated with a 2.5-fold increase in the odds of mortality in both men and women over the first 5 years from diagnosis. Our data strongly support the contention that the mortality risk associated with Type 2 diabetes essentially exists from, or may even predate, the time of diagnosis. 相似文献

AIMS: To evaluate prolonged QTc interval and QT dispersion as predictors of all-cause and cardiovascular mortality after adjustment for well-established risk factors in Type 1 diabetic patients. METHODS: From a cohort of all adult Type 1 diabetic patients, duration of diabetes >or= 5 years, attending the clinic in 1984 and followed in an observational study for 10 years (n = 939), all subjects with resting baseline electrocardiograms were identified (n = 697, 360 males). The QT length was measured and corrected for heart rate (QTc). Maximal QTc length (QTc max) and QT dispersion were determined. RESULTS: At baseline, 431 had normoalbuminuria (< 30 mg/24 h), 138 had microalbuminuria (30-299 mg/24 h) and 128 had macroalbuminuria (>or= 300 mg/24 h) of whom 66 (15%), 35 (25%) and 61 (48%) died during follow-up, respectively (26 (6%), 14 (10%), 21 (16%) from cardiovascular disease). QTc max. was 442 (1.2) ms (mean (SEM)) for survivors and 457 (3.7) in patients who died (P < 0.001). In a Cox proportional hazards model including baseline values of putative risk factors, independent predictors of death were QTc max (P = 0.03), age (P < 0.001), presence of hypertension (P = 0.001), male sex (P < 0.001), log urinary albumin excretion (P < 0.001), smoking (P = 0.04), log serum-creatinine (P < 0.001), height (P < 0.001), low social class (P = 0.04), whereas QT dispersion, heart rate, and HbA1c were not included. In the subgroup with macroalbuminuria, but not for all patients, QTc max was an independent risk factor for cardiovascular mortality. CONCLUSION: QTc prolongation, but not increased QT dispersion, is an independent marker of increased mortality in patients with Type 1 diabetes mellitus. 相似文献

AIM: To determine rates and risk factors for all-cause mortality in African-Americans with Type 1 diabetes from a 3-year observational follow-up study of 725 African-Americans with Type 1 diabetes conducted between 1 January 1999 and 31 December 2001. METHODS: Date of death was ascertained either from telephone contact with the patient's family or from relatives or on line review of the US Social Security death index. RESULTS: Since the initial examination, 131 (18.1%) patients, 60 (20%) men and 71 (17%) women, have died. At the time of death, the mean age of the men was 40.7 +/- 10.6 years and that of the women 39.4 +/- 10.5 years. The median duration of diabetes at the baseline examination was 8.04 years, interquartile range (IQR) 3.76-15.22 years for men and median 10.54, IQR 4.49-18.36 years for women. Three-year mortality rates were 7.1% for women and 10.6% for men. Age-adjusted mortality rates were not significantly different between men and women. Relative to the general US and the New Jersey African-American population, standardized mortality ratios of African-Americans with Type 1 diabetes were 12 and six times greater for women and men, respectively. Older age, low socio-economic status, low body mass index, high diastolic blood pressure, macroangiopathy, proteinuria, severe diabetic retinopathy and heavy alcohol consumption were independent risk factors for all-cause mortality. In patients with microproteinuria at initial examination, the mortality rate for men was twice that of women. CONCLUSION: Microproteinuria and other potentially modifiable factors, including hypertension, macroangiopathy and heavy alcohol consumption, are independent risk factors for mortality in this ethnic group. 相似文献
