Ten out-patients with primary Type IIa hyperlipoproteinemia and a further 10 with Types IIb, IV, and V were administered with DL-alpha-methyl-thyroxine ethyl ester (etiroxate) (20 mg twice daily) for an average of 308 days. The aim of the study was to determine the effects of the drug on the cholesterol and triglyceride levels, tolerance and side-effects, particularly in coronary patients. The T4 values rose in all but one patient and fell again when the drug was discontinued. In Type IIa patients cholesterol fell by an average of 75.5 mg/100 ml (20.6%) as compared with the period before treatment and normal triglyceride levels dropped by 17 mg/100 ml (12.6%). In Type IIb, IV and V patients cholesterol levels decreased by 69.1 mg/100 ml (21%) during treatment. Serum triglycerides, which in some patients were extremely high before treatment were only slightly affected, falling by an average of 165.3 mg/100 ml (22.8%). For the whole group of patients the fall in cholesterol during treatment was highly significant in comparison with the period before and after therapy, whereas the changes in the triglycerides were not significant. Only one patient had an increase in the frequency of angina pectoris attacks; another showed temporary restlessness and slies, were not observed. Red and white cell counts, differential blood count, thrombocytes, the transaminases SGOT, SGPT, alkaline phosphatase, bilirubin, urinalysis and erythrocyte sedimentation rate did not change during treatment. There was no lasting increase in pulse rate in any patient and no significant changes in systolic-diastolic blood pressure. ECG showed no rhythm disorders nor any other changes which were not present before treatment was initiated.

Delayed skin hypersensitivity and serum immunoglobulins were studied in relation to the severity of ischemic heart disease in 18 male monozygotic and 13 male dizygotic twin pairs, aged 55-78 years. The twin pairs were selected from the Swedish Twin Registry. Low IgG was seen in patients with myocardial infarction and definitive angina pectoris. No correlation between skin anergy and the severity of ischemic heart disease was found. These findings may support the possibility that immunological mechanisms play a part in the pathogenesis of ischemic heart disease. Significant F-ratios for IgA and differential white cell count support a genetic determination of these variables.

Platelet size has been shown to reflect platelet activity. We prospectively measured the mean platelet volume (MPV) in 47 patients undergoing single vessel angioplasty for symptomatic angina. The patients underwent repeat angiography 4-8 months later irrespective of symptomatic status. Restenosis was assessed quantitatively by hand held calliper measurements of the lesion and qualitatively by a return of angina, ST segment changes on an exercise test and visual analysis of the lesion severity by two experienced angiographers. Twenty-four patients developed recurrent angina during the follow-up period, the MPV in the group with chest pain was 8.54 +/- 0.60 fl compared to 8.1 +/- 0.69 fl in the asymptomatic group (P = 0.04). Twenty two patients had significant ST segment changes at exercise. In this group the MPV was 8.6 +/- 0.56 fl compared to 8.0 +/- 0.70 fl for the group with a negative test (P = 0.002). Similarly visually assessed angiographic stenosis showed a significant increase in the restenotic group (8.6 +/- 0.56 vs. 8.0 +/- 0.61 fl, P = 0.001). The relative odds for developing clinically defined restenosis were 10.2 times greater if the pre-procedural MPV lay in the upper compared to the lowest quartile. There was a positive correlation between MPV and change in minimal luminal diameter between post angioplasty and follow-up angiography, assessed quantitatively, r = +0.56, P = 0.016. There was no association between clinical or angiographic definitions of restenosis and haemoglobin, red cell count, mean corpuscular volume, white cell count or platelet count. Platelet size may influence the development of restenosis after successful coronary angioplasty.

Authors report their experiences with coronary artery bypass surgery without cardiopulmonary bypass. Between January 1993 and June 1995, 151 patients were operated upon by the same surgeon for ischaemic heart disease (IHD); 7 were of them without extracorporeal circulation (ECC). Patients were selected for the procedure on the following criteria: (1) symptomatic patient with proximally occluded, anteriorly located, major subepicardial artery(ies) unsuitable for, or after failed, PTCA; (2) presence of associated disease (like hypertension, diabetes mellitus, chronic obstructive pulmonary disease) enhancing a possible deleterious effect of cardiopulmonary bypass; (3) favourable response to beta-blocking agent pretreatment without side effects. Seven patients' perioperative data (white cell count, platelet count, whole plasma protein level, chest drainage, CK-MB release--incidence of perioperative myocardial mess loss--and days spent in the intensive care unit /ICU/) are compared to the corresponding data of patients with comparable pathology operated on with ECC. No blood transfusion was required, nor perioperative myocardial necrosis occurred. The patients operated on without ECC spent only 24 hours in the ICU, and the clinical check-up after 1-24 months revealed conditions free from angina pectoris. The patient's quality of life improved.

In the Type 1 diabetes population, coronary heart disease (CHD) and lower-extremity arterial disease (LEAD) are the two common macrovascular complications leading to early mortality and morbidity. However, it is not clear if these two complications share the same risk factors. The Pittsburgh Epidemiology of Diabetes Complications (EDC) Study prospectively examined and compared the risk factors for LEAD and CHD (including CHD morbidity and mortality). EDC subjects (332 men and 325 women), all diagnosed at Children's Hospital of Pittsburgh between 1950 and 1980, were first examined at baseline (1986-1988), and then biennially, for diabetes complications and their risk factors. Data used in the current analysis were from the first 6 years of follow-up, 98% provided at least some follow-up data for these analyses. CHD was defined as the presence of angina (diagnosed by the EDC examining physician) or a history of confirmed myocardial infarction or CHD death. An ankle-to-arm ratio of less than 0.9 at rest was considered to be evidence of LEAD. Among 635 subjects without CHD at baseline, 57 developed CHD (1.69/100 person-years), and among 579 without LEAD at baseline, 70 developed LEAD (2.31/100 person-years). CHD incidence rate was slightly higher in males, while LEAD incidence rate was slightly higher in females. Compared to non-incident cases, subjects who developed either complication were older, had a longer diabetes duration, higher LDL and total cholesterol, and were more likely to be hypertensive. In multivariate analyses, hypertension, low HDL cholesterol level, high white cell count, depression, and nephropathy were the independent risk factors for CHD (including morbidity and mortality). For LEAD, higher HbA1 level, higher LDL cholesterol level and smoking were the important contributing factors. In conclusion, the risk factor patterns differ between the two vascular complications. Glycemic control does not predict CHD overall but does predict LEAD, while hypertension and inflammatory markers are more closely related to CHD than to LEAD.

The prevalence of coronary vasospasm and also the factors associated with coronary vasospasm in CKD is still unclear. In this cross-sectional study of 859 consecutive CKD patients with angina pectoris received coronary catheterization, we evaluated the factors associated with coronary vasospasm. Patients with vasospasm were older and had higher peripheral blood white cell counts, higher peripheral blood monocyte cell counts, higher haemoglobin levels, higher hs-CRP levels, and lower levels of serum creatinine than patients without vasospasm. The results of multivariate logistic regression analysis revealed that peripheral blood monocyte count and hs-CRP level were independently associated with coronary vasospasm in patients with stage 1 CKD. Only peripheral blood monocyte count but not hs-CRP was independently associated with coronary vasospasm in patients with stages 2 and 3 of CKD. In conclusion, peripheral blood monocyte count is independently associated with coronary vasospasm in patients with stage 1-3 CKD, whereas hs-CRP is only independently associated with coronary vasospasm in patients with stage 1 CKD.
