The results showed that the rate of full accord with diagnosis was 75.3%, the rate of basic accord 19.1%, the rate of missing diagnosis 4.5% and the rate of er-roneous diagnosis 1.1%. It is suggested that ultrasonography is of fairly diagnostic value and of its limitations in the diagnosis of heart disease.
The technology of ultrasonic integrated backscat-ter is a new method which is unwound and quantitative to evaluate characterization of tissue. It has been used widely in aspect of liver, kidney, especially heart disease.
Objectives To clarify the clinical significance of the examination of LD 1 and LD 2 on heart disease diagnosis and therapy by comparing and analyzing the difference of the percentage of LD 1 and LD 2 among myocardial infraction group,myocarditis group.
Methods In 57 patients with coronary heart disease, hypertension and dilated heart disease, etc, their systolic and diastolic function of left heart were detected by echocardiography and cardiac catheter. Patients were divided into symptomatic and asymptomatic groups based on NYHA classification.
Results ① The Vp was significantly lowered in patients with cardiac disease than in normal subjects(P< 0.01). Furthermore, the Vp was significantly reduced in 12 patients with E/A≥1(pseudonormalized transmitral flow pattern);
Methods The rate of left ventricular filling flow propagation (Vp) and the early -diastolic peak velocity of the mitral annulus(E) was measured in normal subjects(n=40)and in patients with cardiac disease (n=40).
Methods: A total of 32 cases of normal subjects,82 cases of viral myocarditis,21 cases of rheumatic myocarditis, and 34 cases of benign premature ventricular beats were collected. Myocardial imaging was obtained 90 min after intravenous injection of 185～370 MBq(5～10mCi) of 99m Tc MIBI.
②In 40 patients, the correlation between the Vp and PFR obtained by isotope-angiography test, and the correlation between Vp and E were good(r= 0.83, 0.80 respectively,P< 0.01).
For the clinic-diagnosing disease and cardiac functional evaluation (CFE), it is important to estimate and track the motion of cardiac left ventricle (LV) using Magnetic resonance imaging (MRI) sequences. The motion state of LV can provide the most useful information for the cardiac functional evaluation.
These proteins may be involved in cardiovascular injury, and could play an important role in the treatment of coronary heart disease.
The change of serum leptin and its relationship with platelet membrane glycoprotein Ib in patients with coronary heart disease
The aim of this paper was to investigate the change of serum leptin and its relationship with platelet membrane glycoprotein Ib (GP Ib) in patients with coronary heart disease (CHD).
Changes in the Cardiovascular Function in Healthy Subjects and Patients with Ischemic Heart Disease during Sleep
The examination included 396 subjects: 29 healthy subjects and 367 patients with ischemic heart disease, of whom 149 had left-ventricular failure and 214 hypertension.
Thyrotoxicosis is not only able to aggravate preexisting cardiac disease but can also by itself lead to atrial fibrillation, cardiomegaly or congestive heart failure.
Of major importance is the investigation of the underlying cardiac disease.
Heart transplantation is in our opinion a reconsiderable alternative in the treatment of complex cardiac disease and cardiomyopathy in infants.
The number of women with congenital cardiac disease, who mature into adulthood is increasing.
Insomnia in patients with heart transplantation and cardiac disease is a common problem.
The sensitivity graded echograms of different dBin 30 patients with peri cardial disease were obtained by Aloka SSD-710, Cross-Sectional Scanner. The features of the sensitivity-tomogram-Pair method for the Pericardial membrane were followed.1>The pericardial membrane.

Eighty-nine eases of heart disease were diagnosed with ultrasorography, including 38 cases of rheumatic heart disease, 15 cases of congenital heart disease and 36 cases of other kinds of heart disease. The results showed that the rate of full accord with diagnosis was 75.3%, the rate of basic accord 19.1%, the rate of missing diagnosis 4.5% and the rate of er-roneous diagnosis 1.1%. It is suggested that ultrasonography is of fairly diagnostic value and of its limitations in the diagnosis of heart disease.
tudy of high-frequency electrocardiogram has been developed for more than 40 years of history. But it is still not applied to clinic. The reason is that there are a great number of difficulties left,such as so many fsctors causing high-frequency ECG and its mechanism are unknown,and the idiosyncrasy appears not clear outwardly. In this case,it is hard to verify the existence methods areuSed to solve the problems and purely relied upon. Therefore,the high-frequency ECG is not used asan effective method of clinical...

In this case,it is hard to verify the existence methods areuSed to solve the problems and purely relied upon. Therefore,the high-frequency ECG is not used asan effective method of clinical early diagnosis for the moment. We have worked on the behavior anditS utilization of high-frequency ECG through studying dog's heart as a modelling experiment and indicated the fact that the method of studying the relationship betWeen Statistical toeal notches and slursand some heart discuses currently used by scientists at home and abroad,is not precise. We pointedout that the total numberts of notches and slurs are not the only symptoms with some heart disusesand pattern recognizing and processing,are needed to sdopt supplementary parameters.The proest is subsidiized by National Natural Science Foundation of China.
