Renal failure is an important cause of morbidity and mortality in diabetic patients, who account for up to 25 per cent of new patients entering renal replacement therapy. Between 1980 and 1989, 651 patients with renal failure were treated at King's College Hospital, of whom 177 (27 per cent) had diabetes. Of these 177 patients 148 had diabetic nephropathy (65 non-insulin-dependent), while the rest had other renal diseases. Of the non-insulin-dependent diabetics, 45 per cent (29 of 65) were Asian or Afro-Caribbean compared to only 12 per cent (10/83) of the insulin-dependent diabetics. Ninety-two patients (62 per cent) have received a renal transplant with actuarial patient survival of 82 per cent at 1 year and 61 per cent at 4 years. Both patient and graft survival have been improved by the introduction of cyclosporin A. Continuous ambulatory peritoneal dialysis is the main form of dialysis and has allowed increasing numbers of patients to be dialysed, especially older individuals with non-insulin-dependent diabetes. Rehabilitation is best in those with functioning transplants: 21 patients (19 with functioning grafts) have survived for longer than 5 years. Diabetic complications before and after renal replacement therapy are described. Cardiovascular disease is especially common and may limit the success of renal replacement therapy.

A community cardiovascular disease (CVD) prevention programme was undertaken in 1989 in a Danish County (Vejle). A random sample of 5192 adults were asked to complete a mailed questionnaire on knowledge, attitudes, and behaviour in relation to CVD risk factors. The response rate was 56%. The questionnaire produced baseline data for programme planning and measuring the success of on-going interventions. Smoking, overweight, and unhealthy food habits were the most prevalent CVD risk factors. A CVD risk score was calculated from the data on smoking, food habits, exercise, stress, overweight, self-reported presence of hypertension, diabetes, and gender. A high score was commoner in men, in the least educated, in groups who judged their own risk as high, and in groups with negative health beliefs. The level of knowledge about CVD risk factors was high in general. Low knowledge was commonest in the youngest age group, in the least educated, in unskilled workers, and in groups with negative health beliefs. As social position and personality factors seem to play an important role in actions people may take in prevention of CVD, they should be considered in the planning of the health promotion activities in Vejle.

Epidemiological studies have documented the association between cardiovascular disease and high blood pressure, dyslipidaemia, impaired glucose tolerance, non-insulin-dependent diabetes mellitus (NIDDM), and central obesity. In fact, several of these abnormalities, often all of them, can be identified in the very same individuals, constituting the entity of the multiple metabolic syndrome. Furthermore, many of these abnormalities seem to run in families. These findings raise important questions about the genetic epidemiology of the disease and about the molecular genetic background of the most likely common nominator of this syndrome, namely insulin resistance. Therapeutic actions must also be carefully considered to avoid the encouragement of some abnormalities while treating others.

Non-insulin-dependent diabetes is associated with a 2-3 fold increased risk of cardiovascular disease. The poor relationship between this risk and either glycaemic control or diabetes duration suggests that some other aspect of the diabetic state, and not hyperglycaemia per se, mediates this risk. This other aspect of diabetes does not comprise alterations in recognized cardiovascular risk factors such as blood pressure or lipids, as the major component of the excess risk is in those diabetics with low levels of the other risk factors. It thus appears that there may be some factors that predispose both to diabetes and to cardiovascular disease. In insulin-dependent diabetics most of the excess risk of cardiovascular disease occurs in subjects with proteinuria, and microalbuminuria or proteinuria in non-insulin-dependent diabetics also substantially increases cardiovascular risk. Although changes in recognized risk factors in diabetics with nephropathy may partly explain these observations, we and others have shown that microalbuminuric non-diabetics also have a markedly increased prevalence of cardiovascular disease and substantially increased cardiovascular mortality. The observations that in insulin-dependent diabetics nephropathy shows family clustering and that these patients have elevated sodium lithium counter-transport rate, a possible genetic marker for the vascular complications of hypertension, have led to the suggestion that microalbuminuria may be a marker of a genetic predisposition to vascular disease.(ABSTRACT TRUNCATED AT 250 WORDS)

Hypertension is a powerful predisposing risk factor for cardiovascular disease at all ages and in both sexes. Epidemiological assessment indicates the largest risk ratios for stroke and congestive heart failure (CHF), but coronary heart disease (CHD) is the most common and most lethal sequela of hypertension. Examination of the risk of cardiovascular sequelae in the hypertensive population indicates that this is not uniform and varies over a 10-fold range, depending on the associated risk factors. Systolic pressure merits greater consideration than the diastole pressure because isolated systolic hypertension is a powerful cardiovascular risk at all ages. Furthermore, recent trials have indicated the benefit of therapy for systolic-based hypertension in the elderly, even using a diuretic, for coronary disease as well as stroke. Persons with hypertension have a high prevalence of associated cardiovascular risk factors, including elevated cholesterol, reduced HDL-C, diabetes, left ventricular hypertrophy (LVH), and obesity. About 9% under the age of 65 years have an associated overt cardiovascular disease; above age 65 about 30% are so afflicted. Each of these risk factors can double the risk associated with hypertension. Because they are so common, a large fraction of the disease sequelae of hypertension is attributable to these associated risk factors. The high risk of coronary disease in hypertensive patients is concentrated in those with a high total/HDL-cholesterol ratio, impaired glucose tolerance, high fibrinogen, ECG abnormalities, and cigarette smokers. Stroke risk in hypertensive persons is concentrated in those with cardiovascular disease, diabetes, atrial fibrillation, LVH and cigarette smoking.(ABSTRACT TRUNCATED AT 250 WORDS)

The relation of skin color and mortality from all causes, coronary heart disease, and all cardiovascular diseases was explored in 787 black men and women of the Charleston Heart Study Cohort. Associations were studied by examining rates of mortality during the period 1960-1990 by tertiles of skin color, as measured by reflectometer. Across the tertiles of reflectance there were no significant differences in mortality rates, except for sex differences. Proportional hazard regression analyses were used to investigate the relation between skin color, as a continuous variable, and time to death. Covariates for regression analyses were age, sex, skin color, the interaction of skin color and sex, education, blood pressure, serum total cholesterol, cigarette smoking, body mass index, and history of diabetes. Across the random sample of black men and women there was no significant relation between skin color and time to death, except for lighter skin color and all-cause mortality (p = 0.03). Our study results provided no evidence of a long-term effect of darker skin color, as measured by skin reflectance of light, on mortality from all types of cardiovascular disease, coronary disease, or all causes.

Cigarette smoking is the most preventable cause of cardiovascular morbidity and mortality. Smoking has been associated with a two-to fourfold increased risk of coronary heart disease, a greater than 70% excess rate of death from coronary heart disease, and an elevated risk of sudden death. These risks are compounded in the presence of hypertension, hypercholesterolemia, glucose intolerance, and diabetes, all of which exhibit a synergistic effect with smoking. The relationship between smoking and the risk of peripheral vascular disease has also been well documented. Smokers account for approximately 70% of patients with atherosclerosis obliterans and virtually all those with thromboangiitis obliterans. An association between smoking and cerebrovascular disease remains a matter of debate, although a higher risk of stoke and stroke-related mortality has been observed in smokers than in nonsmokers. Smoking has also been implicated in the development of cor pulmonale, but a direct association with congestive heart failure has not been established. Nicotine and carbon monoxide appear to play major roles in the cardiovascular effects of smoking. Both components adversely alter the myocardial oxygen supply/demand ratio and have been shown to produce endothelial injury, leading to the development of atherosclerotic plaque. Adverse effects on the lipid profile have been noted as well, but the relationship between these changes and the risk of cardiovascular disease remains to be confirmed. Notably, smoking cessation results in a dramatic reduction in the risk of mortality from both coronary heart disease and stroke. In light of the fact that the incidence of smoking has declined primarily among educated sectors of the U.S. population, future efforts must focus on providing effective education, including smoking cessation techniques, to the less-educated groups.

Hyperlipidemia is a well-recognized complication of renal transplantation. In long-term survivors of renal transplantation, cardiovascular disease accounts for the majority of patient deaths. In the cyclosporine era, cardiovascular disease has surpassed infection as the number one cause of death. Risk factors in the transplant population for hyperlipidemia include age, male sex, diabetes, prednisone dose, graft impairment, obesity, and antihypertensive therapy. Recently, cyclosporine has been implicated as an aggravating factor in the development of hyperlipidemia after transplantation, although its role has been controversial. Because renal transplant recipients have other significant risk factors for the development of coronary artery disease, the amelioration of hyperlipidemia may improve long-term patient survival. Because most late deaths occur in patients with a functioning graft, long-term graft survival could also be improved. The role of corticosteroids in the development of hyperlipidemia is well established. Recent studies employing corticosteroid withdrawal after transplantation have shown a marked reduction in cholesterol despite the use of cyclosporine. Data on corticosteroid withdrawal in living related transplants at our center show a significant reduction in total cholesterol after steroid withdrawal. Data from heart transplant recipients under corticosteroid-free protocols show a similar reduction in total cholesterol. Other treatments for hyperlipidemia include diet and cholesterol-lowering agents, such as Mevacor (lovastatin; Merck Sharp & Dohme, West Point, PA). The efficacy of lowering cholesterol in this high-risk population is unknown.

Longitudinal studies have shown a large excess of cardiovascular mortality in insulin-dependent diabetic patients (IDDM) as compared to non-diabetic controls. Although diabetes appears to be an independent cardiovascular risk factor, increases in total and LDL-cholesterol together with a decrease of HDL-cholesterol are more pronounced in diabetics with cardiovascular disease. The general opinion, however, derived from a large number of cross-sectional studies, is that in well-controlled IDDM lipoprotein abnormalities are modest and only slightly different from matched non-diabetic controls. Most of the studies, however, used absolute criteria based on consensus statements and do not take the internal relations of the lipoproteins into account. When atherogenic indices (such as the relationship between total cholesterol and HDL-cholesterol or the Apo A1/apo B quotient) are used, 20 to 30% of an IDDM population considered to be in clinically acceptable control have to be considered pathological. This observation is even more important since the recent Diabetes Control and Complications Trial has shown that, especially in the younger group of patients, significantly higher total cholesterol and triglycerides and lower HDL-cholesterol were observed. Especially in these patients can diet and drug intervention be the most useful in the prevention of cardiovascular disease. These data are consistent with the fact that more sophisticated techniques have previously shown atherogenic changes in the composition of the VLDL-particles and lipoprotein enrichment in apo B. Since these techniques are not easily available in the clinic one has to refer to more classical techniques and the use of above mentioned atherogenic profiles to decide treatment.

We studied the association of glucose intolerance with total and cause-specific mortality during a 5-year follow-up of 637 elderly Finnish men aged 65 to 84 years. Total mortality was 276 per 1000 for men aged 65 to 74 years and 537 per 1000 for men aged 75 to 84 years. Five-year total mortality adjusted for age was 364 per 1000 in diabetic men, 234 per 1000 in men with impaired glucose tolerance and 209 per 1000 in men with normal glucose tolerance. The relative risk of death among diabetic men was 2.10 (95% confidence interval 1.26 to 3.49) and among men with impaired glucose tolerance 1.17 (95% confidence interval 0.71 to 1.94) times higher compared with men with normal glucose tolerance. Cardiovascular disease was the most common cause of death in every glucose tolerance group. The multivariate adjusted relative risk of cardiovascular death was increased (1.55) in diabetic patients, albeit non-significantly (95% confidence interval 0.84 to 2.85). Diabetes resulted in an increased risk of cardiovascular mortality among men aged 65-74 years but not among the 75- 84-year-old men. Relative risk of death from non-cardiovascular causes was slightly increased among diabetic subjects. In conclusion, diabetes mellitus is a significant determinant of mortality among elderly Finnish men.
