In 1983-1988, the results of conservative and surgical treatment of patients with atherosclerotic ischemia of the lower limbs were assessed with the aid of a questionnaire. A possibility of prognosis was assessed with the use of mathematically processed data obtained with such approach. An effect of clinical symptoms (intermittent claudication distance, resting pain, necrosis) and stage of the disease (duration, K/R index) and risk factors (blood cholesterol, triglycerides, diabetes mellitus, ischemic heart disease, arterial hypertension) on the result of surgical treatment was analysed. The obtained results suggest that clinical symptoms and risk factors may predict the results of surgical treatment in the atherosclerotic ischemia of the lower limbs.

Insulin-dependent diabetic patients with diabetic nephropathy have a highly increased morbidity and mortality from cardiovascular diseases. To determine whether altered levels of apolipoprotein(a) (apo(a)), the glycoprotein of the potentially atherogenic lipoprotein(a) (Lp(a)), contribute to the increased risk of ischaemic heart disease, apo(a) was determined in 50 insulin-dependent diabetic patients with diabetic nephropathy (group 1), in 50 insulin-dependent diabetic patients with microalbuminuria (group 2), in 50 insulin-dependent diabetic patients with normoalbuminuria (group 3), and in 50 healthy subjects (group 4). The groups were matched with regard to sex, age and body mass index. The diabetic groups were also matched with regard to diabetes duration. The level of apo(a) was approximately the same in the four groups, being: 122 (x/ divided by 4.2) U l-1, 63 (x/ divided by 4.4) U l-1, 128 (x/ divided by 3.5) U l-1 and 126 (x/ divided by 3.7) U l-1 (geometric mean (x/ divided by antilog SD)) in group 1, 2, 3 and 4, respectively. 1 U l-1 apo(a) approximates 0.7 mg l-1 Lp(a).(ABSTRACT TRUNCATED AT 250 WORDS)

Four patients with postoperative mediastinitis who were treated by omentopexy at the Fukuoka University Hospital between 1989 and 1990. Three of the 4 patients healed successfully, another one died of multiple organ failure 83 days after surgery. All patients were received coronary artery bypass surgery harvesting a left internal thoracic artery for ischemic heart disease. Three patients had diabetes mellitus, one patient had renal failure preoperatively. Recognition of mediastinitis was made by sternal wound purulent discharge and sternal dehiscence. Culture of the discharge fluid yielded methicillin-resistant Staphylococcus aureus in three, and Enterococcus cloacae in one. Irrigation with popidone-iodine or blonopol were ineffective. Thus, the wound was treated with debridement and omentopexy with an omental pedicle flap, respectively. Postoperative course after omentopexy were excellent, had no complications. We conclude that the omentopexy is useful in the treatment of postoperative refractory anterior mediastinitis.

In a population-based study in Taiwan, 11,478 subjects aged 40 years or older were screened for diabetes in one urban and five rural areas. Among the 715 subjects proven to have diabetes, 527 subjects underwent ophthalmoscopy. Diabetic retinopathy was present in 184 of the 527 subjects (35.0%), including background diabetic retinopathy in 157 subjects (30.0%), preproliferative diabetic retinopathy in 15 subjects (2.8%), and proliferative diabetic retinopathy in 12 subjects (2.2%). Diabetic retinopathy was correlated with the duration of diabetes and age at onset of diabetes, type of diabetes treatment, higher serum creatinine levels, and lower serum cholesterol levels. Several other factors, including gender, age, residential area, family income, educational level, control and family history of diabetes, body mass index, physical activity, exercise, cigarette smoking, stroke, ischemic heart disease, leg vessel disease, hypertension, and proteinuria, had no significant association with retinopathy. By multiple logistic regression analysis, duration of diabetes was the most important risk factor related to retinopathy. Diabetic subjects treated with insulin had a higher risk of developing retinopathy than those treated with dietary control (relative risk, 1.57; .05 < P < .10). The univariate analysis disclosed that proliferative diabetic retinopathy was related to older age at examination, older age at onset of diabetes, type of diabetes treatment, and presence of leg vessel disease. Insulin-treated diabetic subjects also had a higher risk of proliferative diabetic retinopathy than patients in whom diabetes was controlled by diet, with a relative risk of 2.51 (.05 < P < .10) in the multiple logistic regression analysis.

The mortality from ischaemic heart disease (IHD) in 35-64 year old Danish men has declined by 27% from 1981 to 1989. In the same period, a lesser increase in mortality from all other causes was observed. However, this is a heterogenous phenomenon, since the mortality from (in particular) infectious diseases (AIDS), diabetes mellitus, and a number of diseases related to heavy drinking has increased, whereas the suicide rate and mortality from lung cancer (in 1985-89) have decreased. It is not possible to evaluate the contribution of improved treatment of IHD cases and a decreasing incidence of disease, respectively, to the decline in mortality from IHD. A decreasing incidence is very probable, however, since both the percentage of smokers and the plasma cholesterol levels in middle-aged men have declined significantly since mid-1970s and leisure time physical activity has increased. The trend in IHD mortality in the 1980s points to a sustained decline in the 1990s and a levelling off in the increase in mortality from other causes. Thus total mortality is expected to decrease more rapidly in the 1990s, resulting in an increase in life expectancy of Danish men.

QT prolongation on electrocardiography is related to sudden cardiac death and is frequently found in alcoholics. We studied QT prolongation in relation to the function of cardiac autonomic nerves assessed by the coefficient of variation of the R-R interval (CVRR) in three age-matched groups of men: 32 alcoholics with autonomic nervous dysfunction (AN), 32 alcoholics without AN, and 32 healthy controls. The QTc interval and CVRR were measured at rest on the 30th day of abstinence, when electrolyte imbalance had disappeared. Subjects with arrhythmia, conduction abnormality, cardiomegaly, ischemic heart disease or diabetes mellitus were excluded. A CVRR of less than 80% of standard predicted value was judged to represent AN. In alcoholics, QTc correlated negatively with the ratio of CVRR to its standard value (r = -0.49, p < 0.0001). The incidence of QTc prolongation was higher in alcoholics with AN (46.9%) than in alcoholics without AN (21.9%, p < 0.05). QTc prolongation was not observed in healthy controls. The QTc interval was significantly (p < 0.01) longer in alcoholics with AN (444 +/- 20 msec) than in alcoholics without AN (426 +/- 17) and in healthy controls (398 +/- 18). These results suggest that alcoholism causes dysfunction of the autonomic nerves as well as worsening QT prolongation, and this may predispose such patients to sudden cardiac death.

The prevalence of silent myocardial ischemia was retrospectively assessed in a group of 100 consecutive patients with angiographically proved coronary artery disease, and diagnostic ECG, by symptom-limited exercise thallium-201 scintigraphy. Twenty-four patients had no evidence of ischemia despite adequate exercise level. So among 76 patients with exercise induced ischemia, only 33 patients (43%) stopped exercise due to anginal pain (symptomatic ischemia: Group 3). And 43 patients with asymptomatic ischemia composed of 23 patients (30%) with ECG change (Group 2B) and 20 patients (26%) without ECG change (Group 2A). Patients background including the history of old myocardial infarction and diabetes mellitus, were similar among Group 2A, 2B, and Group 3. And our major observation was that the extent and severity of quantified SPECT perfusion defects was nearly identical between 3 groups Thus in this study group, there was a rather high prevalence rate of silent ischemia (57%) by exercise thallium-201 criteria. Patients with silent ischemia, associated with positive and negative exercise ECG findings, and those with exercise angina had similar background and comparable amount of jeopardized myocardium.

In one third of patients who suffered an infarction NIDDM and arterial hypertension are present. In the absolute majority of patients with IHD, as apparent from the IRI and C-peptide response after a glucose load, hyperinsulinism is present. The blood sugar response can have the character of diabetes or of impaired glucose tolerance, the curve may be very flat or normal while the IRI and C-peptide response are excessive. Hyperinsulinism has a hypersecretory origin as suggested by the concurrently elevated C-peptide level but also reduced insulin utilization in the liver and peripheral target organs. Hyperinsulinism is thus a regular associated phenomenon of IHD and is a special risk factor independent on hyperglycaemia and associates with the other main risk factors of IHD such as arterial hypertension, HPLP (android obesity), hyperglycaemia (NIDDM) and hirsutism as a manifestation of a hyperandrogenic state in the female organism with the syndrome of polycystic ovaries. Hyperinsulinism plays an indirect role in the pathogenesis of coronary syndrome via the main risk factors (5H syndrome--hyperinsulinism, hypertension, HPLP, hyperglycaemia, hirsutism) and also directly by its action on endothelial paracrine mechanism of the coronary circulation where in the early stage vasoconstrictor factors predominate (endothelin-1, PGF2-alpha) over physiological vasodilatating factors (EDRF-NO, PGE2, PGI2) and this leads then to functional spasms. It seems that also the coronary X syndrome develops very frequently on the background of the hormonal metabolic X syndrome or the 5H syndrome.

The importance of the thrombotic component of coronary heart disease is increasingly recognised, and in particular the role of the coagulation system in this process. The Northwick Park Heart study was the first major prospective study to identify both fibrinogen and factor VIIc as risk factors, as powerful as total cholesterol in predicting ischaemic events. Since then, a number of epidemiological studies have confirmed the importance of fibrinogen, not just in CHD but in stroke as well. A variety of environmental factors are known to influence levels of factor VII and fibrinogen and therefore support their role in the development of coronary thrombosis. Both are known to increase with age and body weight and are relatively elevated in diabetes. Fibrinogen is strongly related to smoking habit and a substantial proportion of the IHD risk associated with smoking is mediated through this relationship. There is a dose response effect between number of cigarettes smoked and level of fibrinogen and an inverse relationship with time since cessation of the habit. Factor VII is known to correlate with total cholesterol level, and there is a relationship between dietary variability of fat intake and factor VII, which is likely to play an important role in the risk of CHD. The case for using either anticoagulation or anti platelet agents in secondary prevention of myocardial infarction is now clear, but there are still uncertainties in primary prevention which relate to the ideal dose intensity of either aspirin or anti-coagulation and the type of patient most likely to benefit. The ongoing Thrombosis Prevention Trial identifies middle-aged males at high risk of a myocardial infarction.(ABSTRACT TRUNCATED AT 250 WORDS)

This study prospectively evaluates the long-term prognosis of patients admitted with chest pain under suspicion of acute myocardial infarction (AMI) with and without confirmed diagnosis. All patients below 76 years of age, free of other severe diseases and alive at discharge, who were admitted to a coronary care unit of a well-defined region during 1 year, constituted the study population. In all, 275 patients with and 257 patients without confirmed AMI (non-AMI) were included. During 7 years of follow-up, 122 cardiac events (96 cardiac deaths and 26 nonfatal AMI) occurred in the AMI patients, and 69 (44 cardiac deaths and 25 nonfatal AMI) were observed in the non-AMI patients. Using univariate analysis, the following risk variables were significantly related to an impaired prognosis of non-AMI patients: age, a history of previous AMI, angina pectoris, clinical heart failure, diabetes and ST or T changes in the electrocardiogram (ECG) on admission. By multivariate analysis, the following risk factors contained independent prognostic information for non-AMI patients: (1) a history of angina pectoris and (2) ST and T changes on the ECG on admission. We conclude that a subset of non-AMI patients at high risk for cardiac events even in the long term can be identified from the medical history and the ECG on admission. These patients should be carefully evaluated prior to discharge, whereas patients without signs of ischemic heart disease have an excellent prognosis.
