Level of blood uric acid in patients with postinfarction heart failure

AIM: To evaluate uric acid (UA) levels in patients with postinfarction chronic cardiac failure (CCF) and to investigate correlation between accumulation of uric acid, CCF severity and some other parameters. MATERIAL AND METHODS: UA levels were determined with enzyme immunoassay and acid-base status of capillary and venous blood was studied in 120 men 35-78 years of age (mean age 46.3 +/- 1.8 years) with CCF of NYHA functional class (FC) I-IV. CCF was caused by Q-wave myocardial infarction in all the patients. RESULTS: It was found that a close direct relationship exists between FC of CCF and UA content (r = 0.735, p < 0.001), FC of CCF and creatinine levels (r = 0.648, p < 0.001). Analysis of acid-base condition shows the existence of compensated gas acidosis in CCF patients. Acid-base changes were more prominent in FC III and IV. FC and gas acidosis directly correlated. CONCLUSION: In CCF there is a pathogenetic relation between high uric acid and hypoxia. However, further studies are necessary of the causes of UC rise in CCF and its influence on the severity of circulatory insufficiency.

Correlation of uric acid, APO-CIII, and apo-E in healthy individuals and patients with coronary heart disease and hypertensive disease

The relationship of the values of serum apolipoproteins and uric acid (UA) was studied in healthy individuals and patients with cardiovascular diseases. It was shown that the development of coronary heart disease (CHD) was attended by the inversion of a correlation between the values of serum apo-CIII and apo-E and UA whereas in patients with CHD these relationships were also significant, but they were negative. It was ascertained that in patients with hypertensive disease there was no significant correlation between the serum levels of apo-CIII, apo-E, and UA.     

The coagulating and anticoagulating blood systems and thrombocyte aggregation in healthy subjects and patients with ischemic heart disease at rest and under physical loading

A study was made of hemostasis, fibrinolysis and platelet aggregation at rest and exercise in 32 healthy persons and 35 patients suffering from coronary heart disease (CHD) with a history of myocardial infarction that had occurred 2-3 months before. It has been discovered as a result that in healthy persons at exercise, the blood coagulation system and fibrinolysis are activated, the level of antithrombin-III rises and initial platelet aggregation decreases. In patients with CHD at exercise, hypercoagulation, deceleration of fibrinolysis, and the decline of the level of AT-III are detectable, with platelet aggregation being enhanced.     

Leu-enkephalin levels in the blood of patients with ischemic heart disease

A total of 32 CHD patients with angina pectoris of effort, functional class I-IV, aged 46 to 68 were examined. Eight patients with cervical osteochondrosis of the same age were controls. In CHD patients with angina pectoris, functional class I-II, the content of leu-enkephalin in the blood plasma did not differ from that in the control group whereas in patients with angina pectoris, functional class II-IV, it was lowered by 42%. In CHD patients aged 46 to 55 the level of leu-enkephalin in the blood plasma was raised, in the group of patients aged 55 to 68 it was considerably lowered.

目的　探讨冠心病 (CHD)与血液C反应蛋白 (CRP)、纤维蛋白原 (FBG)及尿酸 (UA)的关系。方法　对 35例不同类型的CHD患者进行CRP、FBG及UA测定 ,并同 35例健康组比较。结果　CHD组CRP、FBG、UA含量明显高于正常对照组 (均P <0 0 1) ;不同类型的CHD患者中三者的浓度均以急性心肌梗死 (AMI)组增高明显 ;CRP同FBG呈正相关 (r =0 76 3,P <0 0 1)。结论　UA、CRP、FBG同CHD关系密切 ,CRP、FBG是心血管病的危险因素 ,而高UA血症可能独立于其它危险因素对CHD的影响。     

Airway function in healthy subjects and patients with left heart disease.

1. In forty non-smoking healthy subjects and seventy-two patients with left heart diseases measurements were made of the volume expired in the first second of a forced expiration (FEV1) and the total volume expired in a forced expiration (FVC) before and after inhalation of salbutamol. Before and after salbutamol the healthy subjects and patients also inhaled maximally an inspirate, the first part of which contained 133Xe and, during controlled expiration, the radioactivity of the expirate was measured and plotted against its volume. the resulting curves were divided into phases of different slope by eye, the point at which phase 3 changed to phase 4 being nominated the closing volume. 2. In forty non-smoking healthy subjects inhalation of salbutamol was followed by significant increase in FEV1 but FVC and closing volume did not change. 3. Change in posture from seated erect to supine in thirty of these healthy subjects was accompanied by significant reduction in FEV1 and FVC and as closing volume was not significantly different in the two positions the ratio closing volume/vital capacity was increased with recumbency. 4. In seventy-two patients with left heart diseases without a history of cough or wheeze, FEV1, FVC, closing volume and the ratio closing volume/vital capacity were significantly different from values in the healthy subjects. There was no significant difference between non-smokers and ex-smokers amongst the patients. 5. Significant increase in FEV1, FVC and reduction in closing volume and the ratio closing volume/vital capacity followed inhalation of salbutamol in patients with heart diseases but the values remained significantly different from those recorded in the healthy subjects. 6. In twenty patients with heart diseases, FEV1 and FVC were reduced by change in posture from seated erect to supine but the ratio closing volume/vital capacity and the regression with age of this ratio were not significantly changed by change in position. 7. In patients with heart diseases the ratio closing volume/vital capacity was significantly correlated with severity of breathlessness and length of symptom-history but not with left ventricular end-diastolic or pulmonary vein wedge pressures.

Doppler assessment of pulmonary venous flow in healthy subjects and in patients with heart disease

Pulmonary venous flow as assessed by Doppler echocardiography is a current topic of investigation. Pulmonary venous flow has been used recently as part of a comprehensive assessment of left ventricular diastolic filling dynamics in restrictive myocardial diseases and constrictive pericarditis. Abnormalities of flow have been described in dilated cardiomyopathy, congenital heart disease, and arrhythmias. With the advent of transesophageal echocardiography, pulmonary venous flow can be readily obtained in all patients by pulsed-wave Doppler echocardiography. Recently, it has been used to assess the severity of mitral regurgitation and to estimate mean left atrial pressure. This article emphasizes the utility, physiology, and technique of measuring pulmonary venous flow with Doppler echocardiography in health and in disease.
