The characteristics and the prognosis in 921 consecutive patients with acute myocardial infarction (AMI) admitted to one single hospital are described and related to whether they were treated in the coronary care unit or not. Patients treated in the coronary care unit (n = 779) had a 1-year mortality rate of 26% as compared with 41% for patients treated in general wards (n = 115; p < 0.001) and 74% for patients treated in the intensive care unit (n = 27; p < 0.001). Patients treated outside the coronary care unit had a different risk factor pattern including a higher age and a higher prevalence of a previous cardiovascular disease. Independent clinical risk indicators for death among patients in the coronary care unit were in order of significance, high age (p < 0.001), arrhythmia on admission (p < 0.01), acute congestive heart failure on admission (p < 0.01) and a history of diabetes mellitus (p < 0.05). In patients treated in general wards, the only risk indicator for death was a history of congestive heart failure.

According to international consensus, microalbuminuria is defined as an elevated urinary albumin excretion rate (UAER) of 20-200 micrograms/min, which is below the proteinuric range. Nephropathy is a major complication in IDDM, seen in about 30% of patients after many years of diabetes. Increasing microalbuminuria is an excellent marker of subsequent nephropathy in these patients. End-stage diabetic nephropathy is also important in NIDDM, but in most Western countries this serious complication eventually develops in only 5 to 10% of cases, whereas the majority of patients die before this from cardiovascular disease. In completely healthy individuals there is no clear correlation between age and UAER, at least up to about 70 years of age. The mean excretion rate is around 5 micrograms/min, with a considerable range, but excretion only rarely exceeds 15 micrograms/min. In population studies among middle-aged and elderly individuals, higher values are seen. In newly diagnosed NIDDM about 40% of patients show an excretion rate above 15-20 micrograms/min. There is a significant but not precise correlation between albumin excretion rate and glycemic control, and usually UAER is reduced by standard antidiabetic treatment. In a considerable number of patients, high values cannot be reduced. In the course of NIDDM about 20-30% of patients show microalbuminuria. In patients with known diabetes, microalbuminuria is related not only to subsequent diabetic proteinuria, but even more strongly to early death, mainly from cardiovascular disease. Even slight microalbuminuria (15-40 mg/l in early morning urines) is clearly associated with increased mortality. In subjects with newly detected elevated blood glucose (by screening) microalbuminuria also predicts early mortality. The mechanisms are not established, but several arteriosclerosis-related risk factors are seen more frequently in patients with microalbuminuria, e.g. lipid abnormalities, elevated systolic blood pressure (BP), hemostatic measures, as well other markers of cardiovascular disease. Usually there is a significant but not precise correlation between BP and UAER in groups of patients throughout the course of diabetes. New studies document that also in the elderly background population microalbuminuria is a significant risk factor for early death, maybe even stronger than the established risk markers, which thus may be confounded with the presence of microalbuminuria.

Research and development in contraception has only limited interest in women over 35 years old, so we know little about safety, side effects, and effectiveness of contraceptives in this age group. In addition, clinical trials use healthy women which further limits our knowledge about contraceptives in women who have cardiovascular problems, diabetes, and liver conditions. Research does indicate, however, that women with high blood pressure should not take oral contraceptives (OCs) after the age of 35. It also shows that healthy and nonobese women over 35 who do not smoke and have no family history of cardiovascular disease before age 45 can take OCs with 30 mcg of ethinyl estradiol. Practitioners should provide these women with balanced and up-to-date information on the link between OCs and breast cancer and their apparent protective effect against endometrial cancer. The pregnancy rate for 35-39 year old married women using the diaphragm for at least 5 months stands at 1.1/100 women years. Contrary to popular belief, barrier methods can be harmful, e.g., urinary tract infections are more frequent in women who use the diaphragm than in those who do not. Women older than 35 should consider the condom because of its ability to reduce the risk of acquiring HIV or sexually transmitted diseases. Considerable research exists on women over 35 who use copper releasing IUDs. These IUDs are safe in women who do not have heavy menstrual bleeding. The levonorgestrel releasing IUDs are well tolerated in women over 35 since they reduce the amount and duration of menstrual bleeding. Besides users of these IUDs are less likely to have pelvic inflammatory disease and endometritis than those using copper releasing IUDs. Older women in developing countries often undergo hysterectomy for contraceptive purposes and because of heavy bleeding. Tubal ligation is a significant family planning method for older women in developing countries.

An unfavourable body fat distribution has been associated with an increased prevalence and incidence of non-insulin dependent diabetes mellitus (NIDDM). The potential utility of assessing body fat distribution in diabetes screening, however, has not been assessed. We compared the impact of upper body fat distribution (assessed by the waist-to-hip ratio (WHR)) and body mass index (BMI) and NIDDM using the population attributable risk approach of Levin in 1965 Mexican Americans from the San Antonio Heart Study, a population-based study of diabetes and cardiovascular disease. The population attributable risk percentage (PAR%) was 52.0% for WHR compared to 43.4% for body mass index. After stratification by BMI, women with a high WHR had a PAR% of approximately 50% and men had a PAR% of 28-58%. For any given cutpoint (e.g. the 10th percentile, 20th percentile, etc.) of WHR used to screen for NIDDM, WHR had both a higher sensitivity and a lower false positive rate than the corresponding cutpoint of BMI. To evaluate the relative contribution of WHR in identifying prevalent cases of NIDDM, multiple logistic regression analyses were performed, and the number of subjects identified as being in the top 20% of the risk score distribution was compared using a model that included WHR and a model that included BMI. In men, BMI did not increase the sensitivity in detecting NIDDM subjects once age was accounted for; WHR increased the sensitivity only slightly. In women, sensitivity was enhanced modestly using both measures, although WHR again was the more sensitive method. These data suggest that WHR is a better single screening measure for NIDDM than BMI.

Cardiovascular disease constitutes an expanding problem in the elderly because of the increasing size of the aged population. Atherosclerosis, hypertension, and diabetes are responsible for the predonderance of cardiovascular disease, which causes 70% of all deaths beyond age 75. Coronary heart disease (CHD) is the most common and most lethal cardiovascular event in both sexes, exacting a large toll in disability and deteriorated quality of life in old age. Unrecognized myocardial infarctions are especially common and are as serious as symptomatic infarctions. beyond age 65, women are as vulnerable to cardiovascular death as men. The predisposing modifiable risk factors for coronary disease, stroke, peripheral arterial disease, and cardiac failure are similar in young and old and in men and women. These include hypertension, dyslipidemia, impaired glucose tolerance, physical indolence, and cigarette smoking. An attenuated risk ratio for some risk factors is offset by a greater incidence of cardiovascular events in advanced age so that the attributable risk and the potential benefit of treatment rise with age. Because the major risk factors predict CHD as efficiently in the elderly as in the young, and the decline in cardiovascular mortality has included the elderly, preventive efforts in the elderly may have substantial potential benefit. At advanced age, total cholesterol levels are considerably higher in women than in men. Some 10 million elderly, two-thirds of whom are women, may require investigation and treatment for elevated lipid levels, as determined by National Heart, Lung, and Blood Institute (NHLBI) guidelines. Because of the preponderance of women in the elderly population, trials of the efficacy of correcting risk factors in general, and lipids in particular, should include women.

Mounting data support a causal connection between high-normal fibrinogen levels and atherosclerotic cardiovascular disease. There is clearly a thrombogenic component to atherosclerosis and the onset of clinical manifestations. This offers the possibility to better identify high-risk candidates and also to protect them by reducing blood fibrinogen concentration or blocking its action. The relationship of antecedent fibrinogen to the subsequent development of cardiovascular disease is examined, based on 18 years of surveillance of a cohort of 1274 men and women aged 47 to 79 years who participated in the Framingham Study. The association with the development of peripheral arterial disease and cardiac failure is now examined in addition to previously studied relationships to coronary heart disease and stroke. In men and women, there is a significant age-adjusted relationship of fibrinogen level to coronary heart disease and to cardiovascular disease in general. In women, a significant relationship to cardiac failure and peripheral arterial disease, but not to stroke, was also found. These data on women are unique as they are not available elsewhere. Age-adjusted cardiovascular, all-cause, and coronary heart disease mortality were all related to fibrinogen in both sexes. In men, fibrinogen impact was the greatest for stroke and the least for peripheral arterial disease. For women, the impact on coronary heart disease was greatest. The absolute risk for an elevated fibrinogen level was greatest for coronary heart disease in both sexes. Average fibrinogen values are higher in women and in persons with other risk factors, including hypertension, cigarette smoking, diabetes, obesity, and elevated hematocrit. However, there is an independent contribution of fibrinogen to cardiovascular disease in general and coronary disease in particular, on adjustment for coexistent risk factors. Fibrinogen enhances the risk of cardiovascular disease in hypertensives, diabetics, and cigarette smokers. About half the cardiovascular risk of cigarette smoking appears due to the higher fibrinogen values. Now, five prospective studies document the excess incidence of cardiovascular events in persons with elevated fibrinogen levels within the "normal range." Each standard deviation increase in fibrinogen is associated with a 30% increment of coronary heart disease in men and a 40% increase in women. Fibrinogen should be added to the list of major cardiovascular risk factors. Trials of intervention to lower fibrinogen in high-risk coronary candidates are needed.

Cardiovascular risk factors were examined in 453 subjects participating in the Wadena City Health Study, a population-based study to assess the relationship between diabetes and glucose intolerance with age. Each subject was classified as either having non-insulin-dependent diabetes mellitus (NIDDM), impaired glucose tolerance (IGT), or normoglycemia, using WHO criteria. Age- and body-mass-adjusted levels of systolic and diastolic blood pressure were lowest for those with normoglycemia, intermediate for those with IGT, and highest for those with NIDDM. Age- and body-mass-adjusted levels of high-density lipoprotein cholesterol were lowest for those with NIDDM, intermediate for those with IGT, and highest for those with normoglycemia, while triglyceride levels were highest for those with NIDDM, intermediate for those with IGT, and lowest for those with normoglycemia in women but not in men. Low-density lipoprotein cholesterol levels were lowest for those with NIDDM, intermediate for those with IGT, and highest for those with normoglycemia. With the exception of men with IGT, no differences by glycemic strata were observed for plasma total cholesterol. The prevalence of smoking showed no consistent pattern by glycemic status. These findings suggest that individuals with IGT have an atherogenic risk factor pattern that may put them at greater risk for coronary heart disease than those with normoglycemia. Intervention strategies such as diet, exercise, and/or drug therapy should be tested to evaluate whether these are effective in preventing conversion to overt diabetes and normalizing cardiovascular disease risk factors.

The potential influence of postmenopausal estrogen therapy on the subsequent development of non-insulin-dependent diabetes mellitus (NIDDM) is relatively unexplored, despite postulated effects of these hormones on glucose tolerance. We examined the association between postmenopausal hormone use and the subsequent incidence of NIDDM in a prospective cohort of 21,028 postmenopausal US women aged 30 to 55 years and free of diagnosed diabetes, cardiovascular disease, and cancer in 1976. During 12 years of follow-up (422,991 person-years), we confirmed 1249 cases of NIDDM. Current users of postmenopausal hormones had a relative risk of NIDDM of 0.80 (95% confidence interval, 0.67 to 0.96) as compared with never users, after adjustment for age and body mass index (BMI). Past users of these hormones had an age- and BMI-adjusted relative risk of 1.07 (0.93 to 1.23). These results were not materially altered by multivariate adjustment for age, BMI, family history of diabetes, and coronary risk factors. Comparable results were obtained when the analysis was restricted to symptomatic NIDDM as the outcome. We observed no appreciable modification of these associations by family history of diabetes or category of BMI. Duration of current or past use of postmenopausal hormones and dose of conjugated estrogen were not significantly related to incidence of NIDDM. Type of hormone (estrogen alone, progesterone alone, or combination) also did not appear to influence NIDDM risk. These prospective data indicate that postmenopausal hormone therapy is unlikely to be associated with a material increase in the incidence of NIDDM among women.

Lipoprotein(a) [Lp(a)] has been added to the list of independent risk factors for cardiovascular disease (CVD), whose incidence is greater in obese subjects. There are few data available on the serum Lp(a) concentrations in obese individuals with or without insulin dependent diabetes mellitus (NIDDM). We selected 31 obese men with normal glucose tolerance (NGT) tests, 15 obese diabetic men, 14 non obese diabetic men and 17 healthy men as controls. We measured serum total cholesterol, HDL cholesterol, triglycerides, glucose, insulin and Lp(a). The mean Lp(a) levels in NGT obese men were 70.00 +/- 13.40 mg/l, which were similar to those found in normal controls (75.98 +/- 24.70 mg/l); significantly higher mean Lp(a) levels were found in obese diabetic men (168.84 +/- 56.43 mg/l) and in non obese diabetic men (240.85 +/- 63.35 mg/l). No significant correlation between Lp(a) levels and age, body mass index (BMI), total cholesterol, HDL cholesterol, triglycerides, insulin, was found; only a significant positive correlation between Lp(a) levels and glucose could be revealed (P < 0.05). Since higher levels of Lp(a) were found in NIDDM subjects with or without obesity, we conclude that hyperglycemia may influence the levels of serum Lp(a) facilitating its glycosylation in the liver with the consequence of a decline in its catabolic rate.

Raised urinary albumin excretion (UAE) is associated with an increased risk of cardiovascular disease in non-insulin-dependent diabetes mellitus (NIDDM). We have examined the role of endothelial dysfunction as a possible explanation for this association in 94 NIDDM patients by investigating UAE, new cardiovascular events, and plasma concentration of von Willebrand factor (vWF), an indicator of endothelial dysfunction. At baseline, 66 patients had normal UAE (less than 15 micrograms/min), which remained normal in 33 (group 1) and increased in 33 (to median 31.5 micrograms/min, group 2). In 28 patients, baseline UAE was abnormal (67.1 micrograms/min, group 3). Follow-up ranged between 9 and 53 months. vWF did not change in group 1 (median 128% at baseline and 123% at follow-up), but increased in group 2 (from 116 to 219%, p less than 0.0001) and group 3 (from 157 to 207%, p = 0.0005). Baseline level of and change in vWF were strongly related to the development of microalbuminuria (R2 = 0.60, p less than 0.0001), but cardiovascular risk factors were not (R2 = 0.14). Raised baseline UAE was associated with an increased risk of new cardiovascular events only in patients with vWF concentrations above the median (relative risk 3.66, 95% CI 1.3-11.9) and not in patients with lower vWF (0.19, 0.01-1.33). In addition, the cardiovascular risk associated with increased UAE was modified by low compared with high concentrations of serum high density lipoprotein cholesterol (2.86 [1.03-8.48] vs 0.15 [0.01-1.43]). Dysfunction of vascular endothelium may be a link between albuminuria and atherosclerotic cardiovascular disease in NIDDM.
