Apolipoproteins were measured in a prospective blinded fashion in blood specimens from patients with chest pain in the emergency department. A definitive diagnosis for the chest pain (non-cardiac-related in 32% and angina or myocardial infarction in 68%) was available in 136 of the 162 patients originally enrolled in the study. Logistic regression and multivariate analysis failed to show any usefulness of apolipoprotein determinations in distinguishing patients with cardiac ischemia from those without it. The clinician's initial impression of the chest pain, the electrocardiogram, a history of previous angina, myocardial infarction, or peripheral atherosclerosis, and male sex were strongly associated with the final diagnosis. We conclude that, although apolipoprotein analysis has proved useful in epidemiologic studies, the most reliable indicators of ischemic pain remain the medical history, the electrocardiogram, and the clinician's overall initial impression.

The effects of omega-3 polyunsaturated fatty acids (PUSF), a 4-week fish diet--350 g of scomber a day, on the blood lipid-apolipoprotein spectrum were evaluated in 22 patients with primary angina pectoris as compared to 8 control subjects received hospital protein-, fat-, carbohydrate-, and calorie-balanced diet No. 10 differing in omega-3 PUSF content (5 and 0.03 g/day, respectively). The fish diet caused a significant reduction in total cholesterol (TC) and low density lipoprotein cholesterol (LDLC) in patients with hypercholesterolemia, however, the normal cholesterol (under 200 mg/dl) and LDLC (under 130 mg/dl) levels were reached only in a small proportion of the patients. There was a hypotriglyceridemic effect of omega-3 PUSF that was more pronounced at initially high triglyceride concentrations. Heterogeneous changes were found in LDLC levels with the fish diet. i.e. from a great decrease at initially high LDLC levels to a small increase at initially low LDLC in patients with hypertriglyceridemia and low levels of high density lipoproteins. It was concluded that a fish diet should be included into a complex of measures aimed at the secondary prevention of coronary heart disease in patients with primary angina concurrent with hypercholesterolemia (even moderate) and hypertriglyceridemia unassociated with hypoalphacholesterolemia.

The structural homology between plasminogen and apolipoprotein (a), the specific glycoprotein of Lp(a) lipoprotein, raises the possibility of a relationship between this lipoprotein and the plasma fibrinolytic system. The present study examines this proposal by studying 66 patients with angina pectoris. As compared to normal controls, the patients had raised concentrations of Lp(a): B lipoprotein particles. No correlation was found between circulating Lp(a): B and the fibrinolytic system. The pathogenic role of Lp(a): B lipoprotein seems therefore not mediated by its effect on the plasma fibrinolytic system.

A systematic study of 100 elderly patients in a hospital geriatric unit was undertaken to analyse the relationship between clinical cardiovascular events (angina, myocardial infarction, hypertension, cerebrovascular accidents, temporo-spatial disorientation, invalidity, incontinence) and plasma lipids (total cholesterol, HDL and LDL fractions, triglycerides, apolipoprotein A and B and total cholesterol/HDL and apolipoprotein B/A ratios). The average triglyceride and apolipoprotein A concentrations were related to the patient's validity: The triglycerides were significantly higher in the group of invalid patients (+22%), p = 0.05. The apolipoprotein A levels were significantly lower in the invalid group (-12%), p = 0.05.

Lipid and apolipoprotein (apo) levels in patients with variant angina were examined and compared with patients with coronary artery disease (CAD) and normal subjects (control). Cholesterol and triglyceride levels in plasma, lipoprotein fractions and several apolipoproteins were measured in 108 men (90 of whom had undergone coronary angiography): 22 had variant angina, 56 had fixed CAD (effort angina and old myocardial infarction) and 30 were normal subjects. Patients with variant angina showed more severe atherosclerotic lesions than the control group, but less severe lesions than the patients with fixed CAD. In comparison with lipid and apolipoprotein, high density lipoprotein cholesterol, apo AI and apo AII decreased significantly in control, variant angina and fixed CAD groups, respectively. Additionally, stepwise discriminant analysis revealed that apo AI was the best discriminator among the 3 groups or between variant angina or fixed CAD and the control group. Variant angina and fixed CAD patients could be discriminated from the control subjects by an apo AI level of 135 and 126 mg/dl, with 71% (p less than 0.025) and 73% (p less than 0.005) accuracy, respectively. By these criteria 77% of the patients with variant angina and 73% of the patients with fixed CAD were precisely discriminated. Discrimination between variant angina and fixed CAD patients, however, was not practical, even if the best discriminator was used. Thus, the apo AI level is useful in discriminating patients with variant angina and fixed CAD from normal subjects. Therefore, symptomatic patients with low apo AI levels should be aggressively examined.

We examined the association of cholesterol levels in serum lipoprotein fractions, as well as of serum apolipoprotein-AI (apo-AI) and apo-AII levels, with coronary artery stenosis (CAS) and left ventricle function in a group of 43 patients with angina pectoris (33 men and 10 women) subjected to angiography. Cholesterol level in VLDL, LDL, HDL2, and HDL3 fractions was determined after separation of these fractions by density gradient ultracentrifugation. HDL-cholesterol is the sum of cholesterol in HDL2 and HDL3. Cineangiography yielded scores for CAS and for left ventricle ejection fraction (LVEF). On univariate regression CAS was correlated weakly with LDL-cholesterol (positive) and with HDL3-cholesterol and HDL-cholesterol (negative), and more strongly with LDL-cholesterol/HDL-cholesterol (positive), but not with HDL2-cholesterol. LVEF was correlated positively with HDL3-cholesterol, HDL-cholesterol, apo-AI, and apo-AII. Of other "risk factors," none was correlated with CAS, and a history of previous myocardial infarction (PMI) was the only one significantly correlated with LVEF. CAS itself was also correlated negatively with LVEF. In multiple regression analysis with two or three independent variables, the relation of HDL(3)-cholesterol with CAS remained significant when other risk factors were taken into account. LVEF remained related positively with HDL(3)-cholesterol, apo-AI, or apo-AII, when either of them was tested in combination with other risk factors; of these only PMI made a significant independent contribution. Conclusions for this patient group (with low HDL-cholesterol): HDL3-cholesterol, and not HDL2-cholesterol, is informative for CAS; HDL(3)-cholesterol, apo-AI, or apo-AII, as well as CAS and PMI, are associated with LVEF.(ABSTRACT TRUNCATED AT 250 WORDS)

Over the period of one year the authors examined the changes in the parameters of the plasma spectrum of lipoproteins and apolipoproteins in 46 patients with acute macrofocal myocardial infarction and 35 patients with labile angina. In six cases variations in these parameters were studied in the course of unstable angina and in the post-infarction period. It was established that myocardial infarction induced specific alterations in the plasma lipoprotein system not only in the immediate post-infarction period but also at more long-term periods. Myocardial infarction causes deep and prolonged disorders in the apolipoprotein system which may contribute to the progression of atherosclerotic damage to the coronary arteries.

Plasma levels of cholesterol (C), triglycerides (TG), phospholipids (PL) (in total plasma, very low density [VLDL], low density (LDL), and high density [HDL] lipoproteins) and of two apolipoproteins (apo-B and apo-A) were studied in 13 hyperlipidemic patients suffering from hypertension and/or stable angina and treated by metoprolol or propranolol. Propranolol reduced the low density and high density lipoprotein phospholipids by 26% and 11%, respectively, and increased the very low density phospholipids by 24%. Metoprolol had only a transient effect on high density lipoprotein phospholipids. VLDL apolipoprotein-B was markedly increased by propranolol (67%), whereas apolipoprotein-A was slightly (8%) increased during metoprolol treatment. The reduced low density lipoprotein phospholipids and the increased high density lipoprotein apo-A correlated with the plasma concentration of propranolol and metoprolol, respectively. These results suggest that the comparative effects of beta-adrenoreceptor blocking agents on lipoprotein metabolism should be considered in their long-term use in patients with risk factors for hypertension and myocardial infarction.

The authors evaluated physiologic, psychologic and metabolic effects of a nine-week in-hospital training program on 14 men with severe disabling angina pectoris. The exercise program consisted of intensive interval training on an ergometer bicycle for two 30 min sessions daily. The physical performance increased by about 40% (p less than 0.001). Plasma insulin levels were reduced and glucose tolerance improved significantly. There was a decrease in plasma triglyceride and low-density lipoprotein (LDL) cholesterol levels, but no change in high-density lipoprotein (HDL) cholesterol, apolipoprotein AI and B concentrations. Plasma triglyceride (p less than 0.05) and LDL cholesterol (p less than 0.05) levels remained low three weeks after completion of the training period and the physical performance remained improved (p less than 0.01) even six months post-training. Four of the patients who had been disabled for at least five months were able to return to work. The authors suggest that comparatively short and intensive in-hospital rehabilitation of patients with coronary heart disease may be an attractive alternative to prolonged training on an outpatient basis, especially in patients with severe angina pectoris.

102 cases of coronary heart disease (CHD) were divided randomly into two groups, 70 cases were given orally the Buyang Huanwu Decoction (BYHWD) for 15 days and were compared with 32 control patients. The effect of BYHWD in treating angina pectoris and the change of EKG before and after the treatment were observed. The results were as follows: in BYHWD group the serum level of lipoperoxide (LPO), apolipoprotein (apo) B100, LPO/SOD (superoxide dismutase) and apo B100/apo A1 were lowered remarkably, the serum of SOD and apo A1 were elevated significantly (P < 0.01) comparing with the control group. The total effective rate of treating angina pectoris was 91.4%. But the difference was insignificant compared with the control group (P < 0.05). The EKG improvement rate was 85.7% in BYHWD group, the difference was very significant comparing with control group (P < 0.05). The results indicated that BYHWD had a good effect on removing the oxygen free radicals, reducing the injury of LPO and regulating the apolipoprotein metabolism in the patients with CHD. Therefore BYHWD is an effective TCM remedy for CHD.
