Recently new radioimmunoassay methods have been established to measure plasma concentrations of beta-thromboglobulin (beta-TG) and platelet factor 4 (PF4), platelet release products which are set free when platelets aggregate. Plasma concentrations of beta-TG and PF4 were investigated in disorders with increased thromboembolic risk. Extremely high concentrations of these platelet proteins were found in patients with venous thrombosis, pulmonary embolism, polycythemia vera, and chronic renal failure. Moderately increased beta-TG and PF4 levels were observed in patients with peripheral vascular disease, coronary artery disease, chronic rheumatoid arthritis, multiple myeloma, and diabetes mellitus. These data indicate, that plasma concentrations of beta-TG and PF4 are useful parameters for the evaluation of the "in vivo" platelet activity. By using these new methods for clinical applications special blood sampling conditions have been taken into account; moreover one has to consider that the plasma levels of the platelet "release products" are dependent from renal function.

In the course of 5 years, 9509 healthy adult subjects had an average annual incidence of 3.6 unrecognized infarcts per 1000 persons and 5.3 clinical ones per 1000 persons. A multivariate analysis showed that the most significant risk factors were age, left axis deviation, left ventricular hypertrophy, cigarette smoking, systolic or diastolic blood pressure, and peripheral vascular disease. Some of the known risk factors of clinical infarct, or angina pectoris or both, such as cholesterol, diabetes, anxiety, and psychosocial problems, do not play a significant role in unrecognized infarcts. Subjects whose electrocardiograms were initially interpreted by cardiologists as noninfarcts but by the computer as infarcts developed a high rate of unrecognized infarcts in the subsequent 5 years. A 7-year mortality follow-up showed a markedly higher rate among the unrecognized infarct group as compared with the noninfarct population, but significantly lower than those who developed a clinical infarct.

Clinical and coronary arteriographic findings were evaluated in patients with angina pectoris who were considered not to have diabetes mellitus or to have chemical or clinical diabetes. Each of the three groups consisted of 100 consecutive referred patients. Neither the age of the patients nor duration of symptoms differed significantly among the groups. Hypertension, gout, and peripheral vascular disease were more frequent in the patients with clinical diabetes. There was no difference in serum cholesterol concentration among the groups, but plasma triglyceride levels and the frequency of type 4 hyperlipoproteinemia were significantly higher (p less than 0.01) in the chemical and clinical diabetic groups than in the nondiabetic patients. Coronary arteriographic observations indicated that the severity of the coronary arterial disease was greater in both diabetic groups than in nondiabetic patients. The difference in the coronary scores among the three groups of patients interacts to some extent with the triglyceride level, since a high score in the diabetic groups was noted only in the presence of an elevated tryglyceride concentration. The results indicate that the increased severity of coronary arterial disease in diabetic patients is not attributable to age, duration of symptoms, hypertension, type -4 hyperlipoproteinemia, or apparent severity of the glucose intolerance.

This report examines prospectively, in the Framingham cohort, the relation of diabetes and impaired glucose tolerance to each of the cardiovascular sequelae, taking into account age, sex, and associated cardiovascular risk factors. The incidence of cardiovascular disease, as well as the levels of cardiovascular risk factors, were found to be higher in diabetic than in nondiabetic men and women. The relative impact of diabetes on coronary heart disease, peripheral vascular disease, or stroke incidence was the same in men and women, but for cardiovascular mortality and cardiac failure the impact is greater for women. Present evidence suggests that alleviation of associated cardiovascular risk factors is the most promising course in reducing cardiovascular sequelae in diabetic patients.

Atherosclerosis is one of the most common causes of peripheral vascular disease. Complications result from arteries compromised because of focal accumulations of lipids and other materials within and between cells in the vessel walls. Factors including hyperlipidemia, hypertension, diabetes mellitus, obesity, physical inactivity, smoking, social stress, and genetic background have been implicated as promoting a higher risk of atherosclerosis and its consequences.

A study was undertaken to determine the effect of the development or disease on patients' smoking habits. Interviews with 841 subjects (591 smokers) were conducted following a standard protocol. Of the 841 subjects, 96 (61 smokers) had hydroceles or hernias and were considered a control group; the remainder had neoplastic diseases, respiratory disorders, diabetes, cardiovascular diseases, psychiatric illnesses, peripheral vascular diseases, and gastrointestinal and liver disorders. Patients with cardiovascular, pulmonary, and neoplastic diseases, diabetes, gastrointestinal diseases, and cirrhosis of the liver significantly reduced or stopped smoking because of medical advice (19%), socioeconomic factors (8%), or aggravation of disease (24%). The advent of disease was associated with an increase in smoking in several patients (including 2 with bronchial asthma and 12 with peripheral vascular disease) because of the apparent belief that smoking is beneficial in overcoming the disease or in controlling pain. Additional long-term studies are needed to explore the relationship between disease and smoking habits.

Fasting blood sugar levels in hospitalized diabetics with peripheral vascular disease receiving pentoxifylline i.v. and p.o. did not-in comparison to a control group-show statistically significant changes during the observation period in well-controlled, stable diabetes mellitus (BS is less than or equal to 130 mg%); a decrease did occur in hyperglycemic patients. As a hypoglycemic drug effect was not demonstrable in the well-controlled patient-group, the decrease might well be attributable to improved dietary and antidiabetic care during the hospital-stay.

In four groups of persons, 1/healthy individuals, 2/ patients with diabetes mellitus, 3/ patients with peripheral vascular disease, and 4/ patients with hyperthyroidism, the urinary excretion of free cortisol, cortisone, cortisol sulfate and cortisone sulfate was estimated. In groups 2 and 3 the excretion of all four substances was elevated. In hyperthyroidism a preponderance of free cortisone over cortisol was registered. The ratios of the followed substances suggest in patients with peripheral vascular disease a detoriation in the normal excretion of the followed corticoids, based on a preponderance of 11-OH-corticosteroids over their 11-oxo-derivatives. This observation could be implicated in the mild hyperglycemia or decreased glucose tolerance, that is often found in atherosclerotic disease.

623 non-selected diabetic outpatients were screened by the Doppler-ultrasonic-method for peripheral vascular disease. Additional angiologic work up was performed to define the location of stenosis and obliteration. 15.9% of the diabetics were shown to have peripheral vascular disease and 57% of those denied claudication. 9% of the patients had signs of mediasclerosis. The predilection of peripheral vascular disease in diabetics for the arteries below the knee (peripheral type) was confirmed in our study. Patients with a pelvic or femoropopliteal type of peripheral vascular disease showed a high frequency of cardiovascular risk factors. An influence of the duration of diabetes on peripheral vascular disease was not evident. In contrast to this, a significant correlation (p less than 0.001) of the peripheral type of peripheral vascular disease-as well as of mediasclerosis--could be demonstrated with the diabetes of long duration. In patients with the peripheral type of peripheral vascular disease significantly more often higher blood sugar volues were found. Thus the quality of metabolic control seems to be of some importance for this form of diabetic macroangiopathy.

The existence of symptomatic aortoiliofemoral occlusive vascular disease would appear to result in approximately a 10 year decrease in life expectancy compared to that of the "normal" population. However, a significant proportion of the cumulative mortality rate appears to be due to both coronary artery disease and diabetes mellitus, as patients with peripheral vascular disease had a near "normal" life expectancy in the absence of either coronary artery disease or diabetes mellitus. Neither the presence nor the anatomical location of occlusive disease distal to the comon femoral bifurication by itself decreased life expectancy compared to those patients with aortoliofemoral disease but without similar distal occusive disease. Low operative mortality rate, excellent long-term patency, and potentially "normal" life expectancy all encourage an aggressive operative approach in patients with symptoms of peripheral vascular disease but without either diabetes mellitus or coronary artery disease. Revascularization in those patients with diabetes mellitus should be directed at limb salvage rather than at relief of minor symptoms of ischemia.
