81 patients with an average of 61 who had a hemispheric stroke for the first time and survived more than 12 months were followed in order to study the factors related with recovery. The results are: (1). The severity of the initial attack and the presence of depression and other complications in recovery period are the main relating factors with both the quality of life and recovery of neurological deficits. (2). The size of the lesion shown in CT is the main relating factor with the recovery of neurological deficits. (3). function of affected hand is a main relating factor with the quality of life. According to these results, it is essential to have a preliminary consideration to facilitate recovery at the initial stage of stroke and to organize the rehabilitation programs for the patients.

The clinical features, hemodynamic parameters, Wilson's lead and head-chest (H-C) lead ECG of 23 cases with acute right ventricular infarction (ARVI) were analyzed. Results showed that 13 cases revealed clinical right heart failure, but 10 of them had clear lung fields. 11 cases showed hypotension. 20 cases had mean right atrial pressure (MRAP) > or = 10 mmHg. The remaining 3 cases had MRAP between 8 mmHg and 10 mmHg, but it was > or = 10 mmHg after volume loading. The ratio of MRAP to pulmonary wedge pressure was > 0.65 and the right ventricular stroke work index < 5.0 g.m/m2 in all the 23 cases. ST elevation > or = 1 mm in V3R to V6R was found in 12 cases (52%), while ST elevation > or = 1 mm in HV3R to HV8R in 20 cases (87%). The results showed that the diagnostic accuracy for ARVI with H-C lead (right chest) ECG is higher than that with Wilson's lead. H-C ECG is better correlated with hemodynamics in patients with ARVI.

Several erythrocyte biophysical properties (erythrocyte deformability, erythrocyte aggregation and erythrocyte electrophoretic mobility) were investigated in patients with cerebral infarction and in individuals with risk factors of stroke (RFS population; RFSP). Blood viscosity, plasma viscosity, hematocrit, plasma fibrinogen level and yield shear stress (YSS) were also tested. In comparison with the results in a control group, erythrocyte deformability (erythrocyte length under a certain constant shear stress and erythrocyte filterability) was less in both the patient group and the group of RFSP and there is an accompanying increase of erythrocyte aggregation. Blood viscosity and fibrinogen level were higher in the patient groups. There was no correlation between erythrocyte deformability and other hemorheological parameters. Our results suggest that significant alteration of erythrocyte biophysical properties may be implicated in the pathogenesis of ischemic stroke. These abnormalities are associated with some of the risk factors of stroke such as hypertension, atherosclerosis and cardiovascular disorders.

In order to investigate pulmonary artery compliance (Cpa) and its relation with the clinical conditions and the other parameters of pulmonary hemodynamics in patients with chronic obstructive pulmonary disease (COPD), we performed right heart Swan-Ganz catheterization in 146 COPD patients and measured their Cpa with Engelberg's method. The results showed that Cpa of BB type patients was lower than that of PP type ones; patients with pulmonary hypertension or cor pulmonale had lower Cpa than those without. These results suggest that Cpa in COPD patients decreases as their clinical condition worsens. Cpa had close relation with other pulmonary hemodynamic parameters. It had significant negative correlation with pulmonary arterial mean pressure, pulmonary vascular resistance and right ventricular stroke work index and significant positive correlation with cardiac index and stroke volume index. Using Engelberg's method as the standard, we also compared Reuben's, Wang's and Zhong's methods which are all simpler than Engelberg's method for measuring Cpa clinically. The results showed that Cpa measured with Wang's method was the closest to that measured with Engelberg's method.

In order to investigate the relation of impedance rheopneumogram with pulmonary hemodynamics and right ventricular function in patients with chronic obstructive pulmonary disease (COPD), we measured impedance rheopneumogram and did right heart catheterization in 150 COPD patients simultaneously both at rest and after exercise. The results showed that impedance rheopneumogram was mainly influenced by right ventricular after-load, while the influences of right ventricular pre-load, right ventricular contraction, right ventricular stroke work index and cardiac output were rather small, suggesting that in COPD patients impedance rheopneumogram is valuable in predicting pulmonary arterial pressure noninvasively, but not so use in judging the right ventricular function.

Plasma tissue-type plasminogen activator and plasminogen activator inhibitor were determined during the acute, recovery and sequelae stages of patients with ischemic stroke by chromophoric substrate assay. The result showed that t-PA activity was elevated during the acute phase, remained elevated during the recovery stage and declined during the sequelae stage. Lowering of PAI activity was found during acute phase, which reversed during recovery phase and remained significantly elevated during sequelae stage. As a result, the ratio of PAI/t-PA fluctuated during different stages of the disease. Significant elevation of PAI and PAI/t-PA ratio during sequelae stage may be one of the risk factors of further thrombosis and contribute partly to the high relapsing rate of the disease. In addition, a positive correlation was found between PAI and serum cholesterol content.

The prognostic factors in the acute stage of 893 myocardial infarction patients, admitted during a period from 1970 to 1986, were analysed. The overall mortality was 15.6%, including 14.4% cardiac death and 1.1% non-cardiac death. Single factor analysis indicated that age, sex, occupation, history of hypertension, chest pain during the episode, systolic blood pressure, heart rate and site of infarction at the time of admission, presence of complications such as cardiogenic shock, arrhythmias, stroke and monitoring in CCU or not were related to the overall mortality and cardiac death. Multiple factor logistic regression analysis indicated that for the overall mortality, the independent prognostic factors included presence of cardiogenic shock, heart rate and chest pain at the time of admission; for the cardiac death, the independent factors included age, occupation, history of hypertension, heart rate and chest pain at the time of admission, involvement of anterior wall and presence of cardiogenic shock and arrhythmias. Basing on the above findings we establish a risk factors predicting prognostic model of acute myocardial infarction in its acute stage.

754 cases of acute myocardial infarction survivors were followed up for 28 days to 14 years, the missing rate was 1.86%. The factors influencing long-term prognosis were analyzed. Single factor analysis revealed sex, occupation, age, amount of cigarette smoked, history of stroke, and COPD, complications of heart failure, and arrhythmia, stroke and COPD, heart rate higher than 110/min, lung rales, frequency of infarction, quit smoking after infarction exerted significant influence on over all and cardiac death rate. Multiple factors Cox model analysis revealed quit smoking, complications of stroke heart failure, arrhythmia and occupation were the independent predicting factors for over-all causes of death. Frequency of myocardial infarction, quit smoking, amount of cigarette smoked, occupation, stroke were the independent prognostic factors of cardiac death.

The maximal binding capacity (Ro) and dissociation constant (Kd) of glucocorticoid receptor (GCR) in peripheral leukocytes were estimated by radioligand binding method and the plasma cortisol levels measured in 25 stroke patients (hemorrhagic 15, ischemic 10), compared with 12 healthy controls, the plasma cortisol level in stroke patients were significantly higher. The plasma cortisol level of 15 hemorrhagic and 10 ischemic stroke patients and 12 controls determined by RIA were 1.12 +/- 0.21, 0.90 +/- 0.28 and 0.45 +/- 0.09 nmol/L respectively. Ro of leukocytic GCR in hemorrhagic stroke were significantly lower than that of ischemic stroke and controls. No difference was found between ischemic stroke and controls. No difference was found between ischemic stroke and controls. Ro of GCR in 15 hemorrhagic stroke, 10 ischemic stroke patients and 12 controls were 3496 +/- 424, 5678 +/- 1101 and 5940 +/- 763 sites/cell respectively kd of GCR were 10.47 +/- 4.17, 7.01 +/- 3.24 and 5.81 +/- 1.05 nmol/L respectively. Affinity of GCR in 15 hemorrhagic stroke patients was significantly lower. In conclusion, lower number and affinity of leukocytic GCR and higher plasma cortisol level were demonstrated in hemorrhagic stroke patients, but normal number and affinity of GCR and higher plasma cortisol level in ischemic stroke patients.

Left ventricular function, both systolic and diastolic, was examined in 16 normal subjects and 62 patients of acute viral myocarditis with radionuclide angiocardiography. The results of patients as compared with those of normal showed that left ventricular ejection fraction, the peak ejection rate, the peak filling rate, the relative stroke volume and the relative cardiac output were lower (P less than 0.01 - 0.05). The phase angle from phase analysis was wider (P less than 0.01). Hypokinesia was noted by the observation of left ventricular wall motion 57 of 62 cases correlated well relative with the reduction left ventricular ejection fraction. Hypokinesia of left ventricular wall motion seems to be a more sensitive index than decrease of left ventricular ejection fraction for the diagnosis of acute viral myocarditis.
