Background and Purpose The risk of stroke is known to be markedly elevated in patients with non–insulin-dependent diabetes mellitus (NIDDM), but the information on risk factors predicting stroke events in middle-aged NIDDM patients is limited. Therefore, we evaluated the significance of different cardiovascular risk factors with respect to the incidence of stroke in middle-aged NIDDM patients.

Methods Levels of cardiovascular risk factors were determined at baseline in 1059 NIDDM patients (581 men, 478 women) and 1373 nondiabetic control subjects (638 men, 735 women), aged from 45 to 64 years, in eastern and western Finland. These patients were followed up for 7 years with respect to stroke events.

Results Altogether, 34 NIDDM patients (13 men, 21 women) and 5 nondiabetic subjects (4 men, 1 woman) died from stroke, and 125 NIDDM patients (61 men, 64 women) and 30 (18 men, 12 women) nondiabetic subjects had a fatal or nonfatal stroke. The risk of stroke in NIDDM men was about threefold and in NIDDM women fivefold higher than that in corresponding nondiabetic subjects. Previous history of stroke increased the risk of a new stroke event by threefold. Patients with hyperglycemia (plasma glucose >13.4 mmol/L) and high hemoglobin A1 (>10.7%) had about a twofold higher risk of stroke than patients with better glycemic control. Low levels of high-density lipoprotein cholesterol (<0.90 mmol/L), high levels of total triglyceride (>2.30 mmol/L), and the presence of hypertension were associated with a twofold increase in the risk of stroke mortality or morbidity.

Conclusions Our prospective population-based study gives evidence that previous history of stroke, hypertension, hyperglycemia, and dyslipidemia are strong predictors of stroke in middle-aged patients with NIDDM.

Several studies have indicated that NIDDM increases the risk of ischemic stroke.1 In the Framingham Study, the risk of stroke was 2.6-fold higher in men with NIDDM and 3.8-fold higher in women with NIDDM than in nondiabetic subjects of the corresponding sex.2 Furthermore, diabetic patients have more severe strokes and a higher mortality rate after stroke.3

Hypertension is the strongest predictor of stroke in nondiabetic subjects as well as in patients with NIDDM.2 4 5 Other established risk factors for ischemic stroke include age, male sex, smoking, and atrial fibrillation.6 7 Moreover, factors related to the diabetic state itself (eg, hyperglycemia) might be important with respect to the risk of stroke,8 9 but our knowledge on that subject is still limited.1 Furthermore, no information is available on dyslipidemia as a predictor of stroke in NIDDM patients.

The aim of this prospective population-based study including large cohorts of NIDDM patients and nondiabetic subjects was to investigate risk factors for stroke morbidity and mortality in patients with NIDDM.

Research Design and Methods at the Baseline Study
Patients With NIDDM
All diabetic patients in Finland who need antidiabetic drug therapy receive it free of charge according to the Sickness Insurance Act. The Social Insurance Institution maintains a central register of diabetic subjects receiving drug reimbursement. On the basis of information from this register, we identified all diabetic patients aged 45 to 64 years born and living in the Kuopio University Hospital district (East Finland) and in the Turku University Central Hospital district (West Finland). From this data source, the patient population enrolled in this study consisted of 510 diabetic subjects (253 men, 257 women) from East Finland (participation rate, 83%) and 549 diabetic subjects (328 men, 221 women) from West Finland (participation rate, 79%), as has been previously described in detail.10 Insulin-dependent diabetes was excluded in all insulin-treated NIDDM patients by C peptide measurements. All NIDDM patients included in the final study population had a plasma C peptide concentration of at least 0.20 nmol/L 6 minutes after administration of 1 mg IV glucagon. A cutoff point of 0.20 nmol/L was chosen because postglucagon C peptide values below this limit have been shown to be associated with the occurrence of ketoacidosis in insulin-treated diabetic subjects.11 None of the patients classified as having NIDDM according to the WHO criteria12 and included in the study population had a history of ketoacidosis. Of the 510 NIDDM patients from East Finland, 46 men and 38 women were treated with diet only, 183 men and 175 women with oral hypoglycemic drugs, and 24 men and 44 women with insulin. Of 549 NIDDM patients from West Finland, 46 men and 17 women were treated with diet only, 227 men and 177 women with oral hypoglycemic drugs, and 55 men and 27 women with insulin. The age of diabetic men from East Finland was 56.8±0.3 years, and from West Finland it was 57.2±0.3 years; the age of diabetic women from East Finland was 58.9±0.3 years, and from West Finland it was 58.7±0.3 years.

Nondiabetic Subjects
A random control-population sample of subjects who were born in the Kuopio University Central Hospital district (East Finland) or in the Turku University Central Hospital district (West Finland) and were living in these areas was taken from the population register containing all subjects aged 45 to 64 years. The details of formation of these nondiabetic samples have been published previously.10 Participation rates were 79% in East Finland and 85% in West Finland. The study population consisted finally of 649 subjects (313 men, 336 women) in East Finland and 724 subjects (325 men, 399 women) in West Finland. The age of nondiabetic men from East Finland was 53.8±0.3 years, and from West Finland it was 54.5±0.3 years; the age of nondiabetic women from East Finland was 54.6±0.3 years, and from West Finland it was 54.0±0.3 years.

Study Program and Methods at Baseline Examination in 1982-1984
The study program for both diabetic and nondiabetic subjects was carried out during one outpatient visit at the Clinical Research Unit of the University of Kuopio or the Rehabilitation Research Centre of the Social Insurance Institution in Turku. These methods have been described previously.10 The visit included an interview on the history of chest pain symptoms suggestive of coronary heart disease, smoking, alcohol intake, physical activity, and the use of drugs. All medical records of those subjects who reported in the interview that they had been admitted to the hospital on the basis of chest pain or symptoms suggestive of stroke were reviewed. Review of the medical records was performed by two of us (M.L. in Kuopio and T.R. in Turku) after a careful standardization of the methods and after training sessions among the reviewers. The WHO criteria for verified definite or possible myocardial infarction based on chest pain symptoms, electrocardiographic changes, and enzyme determinations were used in the ascertainment of the diagnosis of previous myocardial infarction.13 The WHO criteria for verified definite or possible stroke were used in the ascertainment of the diagnosis of previous stroke, which was defined as a clinical syndrome consisting of neurological symptoms persisting for >24 hours.14 Thromboembolic and hemorrhagic strokes, but not subarachnoid hemorrhage, were included in the diagnosis of stroke.

Blood pressure was measured with a mercury sphygmomanometer with the subject in the sitting position after a 5-minute rest and read to the nearest 2 mm Hg. A subject was classified as having hypertension if he or she was receiving drug treatment for hypertension or if systolic blood pressure was at least 160 mm Hg or diastolic blood pressure at least 95 mm Hg.

Weight and height were measured with the subject in light clothing without shoes. BMI was calculated by weight (kilograms) divided by height squared (meters squared).

Biochemical Methods
All laboratory specimens were drawn after a 12-hour fast at 8 AM. The analyses were performed in duplicate except for GHbA1. Fasting plasma glucose was determined by the glucose oxidase method (Boehringer). GHbA1 was determined by affinity chromatography (Isolab). The plasma C peptide response to glucagon was assessed according to the method of Faber and Binder.15 Plasma C peptide was determined by radioimmunoassay (antiserum M 1230, Novo).16 Serum lipids and lipoproteins were determined from fresh serum samples drawn after a 12-hour overnight fast. Serum total cholesterol and triglyceride levels were assayed by automated enzymatic methods (Boehringer).17 Serum HDL cholesterol was determined enzymatically after precipitation of low-density and very-low-density lipoproteins with dextran sulfate–MgCl2.18 Urinary protein concentration was measured by the Coomassie brilliant blue method (Bio-Rad Laboratories).

Research Design and Methods of Follow-up Study
In 1990, a postal questionnaire containing questions about hospitalization because of acute chest pain and symptoms suggestive of stroke was sent to every surviving participant of the original study cohort. All medical records of those subjects who had died between baseline examination and December 31, 1989, or who reported in the questionnaire that they had been admitted to the hospital because of symptoms suggestive of stroke between the baseline examination and December 31, 1989, were reviewed by one of us (S.L.). To ensure that the data collection was complete, a computerized hospital discharge register was used to check hospital admissions of all participants of the baseline study, and in cases of hospitalization for stroke, medical records were also checked. Copies of death certificates of those patients who had died were obtained from the files of the Central Statistical Office of Finland. In the final classification of the causes of death, hospital records and autopsy records were used if available. Causes of death were coded according to the International Classification of Diseases, 9th Revision (ICD-9).19

WHO criteria for verified and possible stroke used in the ascertainment of a new stroke event were similar to those used in the baseline study, ie, a clinical syndrome consisting of a neurological deficit and persisting >24 hours (nonfatal stroke), without the presence of other diseases that explained the symptoms.14 Causes of death from stroke included ICD-9 codes 431 through 434. Thus, thromboembolic and hemorrhagic stroke, but not subarachnoid hemorrhage, were included in the diagnosis of stroke.

Statistical Methods
Data analyses were conducted with the SPSSX and SPSS/PC+ programs (SPSS Inc). The results for continuous variables are given as mean±SEM and for categorical variables as percentages. The differences between the groups were assessed by the {chi}2 test or Student's two-tailed t test for independent samples, as appropriate. Univariate and multiple logistic regression analyses based on the maximum-likelihood method were used to investigate the association of cardiovascular risk factors with the incidence of coronary heart disease events, and the results are reported with 95% CIs. Mantel-Haenszel's test for linear association was used to evaluate the association of the tertiles of serum lipids and lipoproteins, glycemic control, and the duration of diabetes with the risk of stroke events. Because triglyceride concentration was not normally distributed, it was log transformed in all statistical analyses.

Approval of Ethics Committee
This study was approved by the Ethics Committee of Kuopio University Central Hospital.

During the follow-up, 23 NIDDM patients (7 men, 16 women) and 3 nondiabetic men from East Finland and 11 NIDDM patients (6 men, 5 women) and 2 nondiabetic subjects (1 man, 1 woman) from West Finland died of stroke. Altogether, 68 NIDDM patients (27 men, 41 women) and 16 nondiabetic subjects (10 men, 6 women) from East Finland and 57 NIDDM patients (34 men, 23 women) and 14 nondiabetic subjects (8 men, 6 women) from West Finland had a fatal or nonfatal stroke event.

Diabetic men had a twofold to threefold higher and diabetic women a fivefold higher risk for stroke than corresponding nondiabetic subjects (men: OR, 2.4 [95% CI, 1.2 to 4.9] in East Finland; OR, 3.3 [95% CI, 1.6 to 6.9] in West Finland; women: OR, 5.5 [95% CI, 2.4 to 12.9] in East Finland; OR, 5.4 [95% CI, 2.3 to 12.6] in West Finland). Because none of the nondiabetic women in East Finland died from stroke during follow-up, it was not possible to calculate ORs for this subgroup. The results were essentially similar when subjects with a history of stroke before the baseline study were excluded. Ischemic stroke was the most common cause of stroke in nondiabetic subjects and NIDDM patients in both areas.

All of the following data analyses concern only NIDDM patients because the small number of stroke events in nondiabetic subjects did not allow any further statistical analyses. Furthermore, both study areas were combined in the following analyses because the results were essentially similar in both areas.

Table 1Down summarizes baseline characteristics for NIDDM men and women in relation to stroke events during 7-year follow-up. NIDDM men with stroke were significantly older and more often had a history of previous stroke (P<.05) and higher level of triglycerides (P=.001) and lower level of HDL cholesterol (P<.05). In addition, NIDDM men with stroke had higher levels of plasma glucose (P<.01) and GHbA1 (P=.01) than those without stroke. NIDDM women with stroke more often had a history of stroke (P<.001); they were also more often hypertensive (P<.001) and had higher total serum total cholesterol (P=.01), total triglyceride (P<.05), and fasting plasma glucose (P<.05) levels, as well as a longer duration of diabetes (P=.01), than NIDDM women without stroke.

Table 1. Levels of Cardiovascular Risk Factors in Relation to the Occurrence of Fatal or Nonfatal Stroke During 7-Year Follow-up in Patients With NIDDM

The risk of stroke in NIDDM patients (men and women combined) was investigated by calculating age- and sex-adjusted ORs for different cardiovascular risk factors by univariate logistic regression analysis (Table 2Down). Cutoff points for high total (>6.2 mmol/L) and low HDL cholesterol (<0.90 mmol/L) and high total triglyceride (>2.30 mmol/L) levels were based on high-risk category classification of the National Cholesterol Education Program.20 The cutoff points for high plasma glucose (>13.4 mmol/L), GHbA1 (>10.7%), and long duration of diabetes (>9 years) were based on the highest tertile cutoff points for these variables. The cutoff point of 27 kg/m2 for BMI was used to define obesity. Previous history of stroke was associated with a threefold increased risk for stroke. Low HDL cholesterol, high triglyceride levels, and hypertension were associated with a twofold risk for stroke. Furthermore, high fasting glucose was associated with an almost threefold increased risk, and high GHbA1 and a long duration of diabetes were associated with an almost twofold increased risk of stroke. High total cholesterol tended to be associated with stroke, but the association did not reach the conventional limit of statistical significance (P<.07). Obesity and smoking were not associated with an increased risk of stroke.

Table 2. Age- and Sex-Adjusted ORs for Risk of Fatal or Nonfatal Stroke (125/1059) and 95% CIs Estimated by Univariate Logistic Regression Analysis During 7-Year Follow-up in Patients With NIDDM

Fig 1Down reports stroke events in NIDDM patients (men and women combined) according to different lipid tertiles and factors related to glycemic control. High serum total cholesterol (P<.01), low HDL cholesterol (P<.01), high triglycerides (P<.001), high plasma glucose (P<.001), high GHbA1 (P<.001), and long duration of diabetes (P<.05) increased the risk of stroke. These variables were risk factors for stroke also when the data were analyzed separately for men and women.

I indicates lowest tertile; II, middle tertile; and III, highest tertile.

Because hyperglycemia was a strong predictor for stroke, we further investigated whether this association was independent of other cardiovascular risk factors. Adjustment for age, sex, area of residence, previous myocardial infarction, previous stroke, total cholesterol, total triglycerides, smoking, BMI, hypertension, HDL cholesterol, atrial fibrillation, and duration of diabetes did not abolish the association of high plasma glucose with stroke (OR, 2.6; 95% CI, 1.5 to 3.8). We also analyzed whether the predictive value of serum lipids with respect to stroke events was modified by the degree of hyperglycemia. This was done by dividing diabetic patients into two groups on the basis of the highest tertile of baseline fasting plasma glucose level >13.4 mmol/L. The cutoff points for high total cholesterol (>6.20 mmol/L), low HDL cholesterol (<0.90 mmol/L), and high total triglyceride (>2.30 mmol/L) levels were based on high-risk category classification of the National Cholesterol Education Program,20 as mentioned earlier. Fig 2Down demonstrates that high total cholesterol, low HDL cholesterol, and high total triglycerides increased the risk for stroke both in patients with poor metabolic control (plasma glucose >13.4 mmol/L) and in patients with better glycemic control (plasma glucose <=13.4 mmol/L). However, when the risk of stroke was evaluated within each lipid category, hyperglycemia still increased the incidence of stroke events significantly.

Figure 2. Bar graphs show 7-year incidence (%) of fatal or nonfatal stroke events with respect to serum total cholesterol (CHOL; cutoff point, 6.20 mmol/L), HDL cholesterol (cutoff point, 0.90 mmol/L), and total triglycerides (TG; cutoff point, 2.30 mmol/L) in low (<=13.4 mmol/L) and high plasma glucose (Gluc; >13.4 mmol/L) categories in patients with NIDDM.

We also evaluated the incidence of stroke by the mode of treatment. The incidence of stroke mortality or morbidity was 5.4% in patients treated with diet, 11.2% in patients treated with oral hypoglycemic drugs, and 21.3% in patients treated with insulin (P<.001 among the groups). However, after adjustment for age and sex and for variables that reflect the severity of diabetes (fasting plasma glucose, the presence of proteinuria, and diabetic retinopathy) no statistically significant differences were found between insulin-treated patients and patients treated with diet only or with oral hypoglycemic drugs with respect to the incidence of all stroke events.

Our 7-year follow-up study based on representative cohorts of nondiabetic and diabetic subjects from Finland demonstrated that NIDDM increased the risk of stroke significantly. NIDDM women were about five times more likely to experience a stroke compared with nondiabetic women. The risk of stroke for diabetic men was two to three times higher than that for nondiabetic men. Our study also confirmed the finding that hypertension is a risk factor for stroke in diabetic patients.4 21 22 23

The main finding of the present study was a strong association of hyperglycemia with stroke in NIDDM patients. In fact, high fasting plasma glucose was a risk factor for stroke even after adjustment for other variables. In addition to fasting plasma glucose, glycemic control was also assessed by GHbA1, which reflects hyperglycemia during the preceding 2 months.24 25 26 There was a dose-response relationship between GHbA1 and risk of stroke (Fig 1Up). The duration of diabetes was also an important risk factor for stroke events in NIDDM subjects (Table 2Up). However, the effect of the duration of diabetes was a significant predictor of stroke events only after 9-year duration of disease. The failure of previous studies to demonstrate an association between stroke risk and the duration of diabetes may be due to a narrow range of duration of disease in these studies.

The importance of GHbA1 and the duration of diabetes as predictors of stroke in the present study is in accordance with the recently published study of the predictors of stroke in an elderly Finnish population including a representative cohort of NIDDM subjects aged 65 to 74 years.9 In that study, fasting plasma glucose and GHbA1 were the strongest predictors of stroke in NIDDM subjects, outweighing all classic risk factors for stroke, but the duration of diabetes was also a predictor of stroke independent of the degree of hyperglycemia. These findings, in addition to ours, give convincing evidence that poor metabolic control, reflected by high blood glucose and GHbA1, is a major risk factor for stroke, independent of age.

Poor metabolic control accelerates diabetic microvascular disease, but the importance of hyperglycemia with respect to macrovascular disease in NIDDM is still controversial.1 27 There are several mechanisms by which hyperglycemia causes atherosclerosis. First, hyperglycemia is related to atherogenic lipoprotein changes.8 Second, hyperglycemia is also a procoagulant state. Accelerated production of von Willebrand factor and fibrinogen and decreased formation of prostacyclin in the diabetic state increase thrombosis formation.8 28 29 Hyperglycemia also causes glycosylation of proteins in the artery wall.30

Hypertriglyceridemia is the most common lipid abnormality in patients with NIDDM. The level of total cholesterol may be elevated, and HDL cholesterol is often decreased.8 31 32 Although lipid abnormalities have been shown to be associated with cerebral atherosclerosis, data on the relationship between dyslipidemia and stroke are limited.33 34 In our study, there was a strong relationship between low HDL cholesterol and stroke in patients with NIDDM. In previous studies, this association has been reported only in men.35 36 Moreover, previous studies have failed to show a relationship of high serum cholesterol and triglyceride levels with the risk of stroke in patients with NIDDM.35 36 In the present study, there was a dose-response relationship between total cholesterol, HDL cholesterol, and triglycerides and the risk of stroke events in NIDDM subjects (Fig 2Up).

What is the explanation for the association of hypertriglyceridemia, low HDL cholesterol, and the risk for stroke? Impaired fibrinolysis has emerged as a new risk factor for ischemic heart disease. Fibrinolytic activity in blood is regulated mainly by plasma PAI-1.37 Moreover, increased levels of PAI-1 have been demonstrated in patients with NIDDM38 and in patients with coronary heart disease37 39 and stroke.40 Furthermore, triglyceride level has been shown to correlate with PAI-1.41 Although we did not measure PAI-1 activity, impaired fibrinolysis could be one of the mediating factors between dyslipidemia and the risk of stroke.

In conclusion, our study with follow-up for up to 7 years gives evidence that poor glycemic control is a strong risk factor for stroke in patients with NIDDM. Furthermore, previous stroke, hypertension, high cholesterol, high triglycerides, and low HDL cholesterol are important predictors of future risk of stroke in patients with NIDDM. Our results imply that effective treatment of hyperglycemia, hypertension, and dyslipidemia may help to prevent stroke in patients with NIDDM.
