Lege Artis Medicinae - 1993;3(09)

[Symptoms of ischemic heart disease will occur when myocardial perfusion diminishes below a critical level. Coronarography will disclose the anatomic stenoses, but there is no direct correlation between the grade of stenosis and the change of myocardial perfusion. Myocardial contrast echocardiography is a new technique to analyze the myocardial perfusion. The contrast agent contains micro bubbles which have nearly the same dimensions as red blood cells. The microbubbles increase the „whiteness" of the perfused myocardium during the echocardiographic examinations. The change in „whiteness" of the myocardium correlates with myocardial perfusion. Intracoronary injections delineate the perfusion area of the coronary artery, and Thus the coronary flow reserve and the collateral flow area can be measured. The cardioplegia fluid distribution and the graft perfusion area are examined intraoperatively. Bedside myocardial perfusion studies will be possible through the transpulmonary passage of intravenously injected contrast agents. Myocardial contrast echocardiography can be applied both in the diagnosis and treatment of ischemic heart disease.]

[What to expect of PTCA today?]

MAJOR László, MOLNÁR Ferenc, BERENTEY Ernő, KÉKES Ede

[This article is a review of the changing indications for percutaneous coronary angioplasty during the last decade. The role of revascularisation and especially of PTCA in the treatment of coronary heart disease is explained. Coronarography is the most important morphol gic diagnostic tool for coronary artery disease. The importance of the topic of this article is enhanced by the position of Hungary at the top of morbidity and mortality statistics, and by the infrequency of revascularisation procedures, especially PTCA. PTCA proved to be a real alternative to a surgical procedure in about half of the patients indicated for revascularisation. PTCA is less invasive, requires less time for recovery and is less expensive compared to bypass surgery. This article should draw attention of the family practitioner to the importance of this method. ]

[Randomised assessment of (the effect of) digoxin on inhibition of the angiotensin-converting enzyme study]

MATOS Lajos

[Circulatory failure worsened to the point of discontinuation in 23 patients in the diuretic + ACE inhibitor + placebo only group, compared to only four patients in the digoxin group (p<0.001). The relative odds of worsening circulatory failure with placebo compared with digoxin was 5.9. All measured parameters of functional capacity (maximal exercise capacity, submaximal exercise capacity, NYHA grade) worsened with digoxin withdrawal. Similarly, quality of life (p=0.04), ejection fraction (p=0.001), heart rate (p<0.001) and body weight (p<0.001) decreased with digoxin instead of placebo.]

[Investigation of uterine circulation by transvaginal color doppler in early pregnancy]

SZABÓ István, CSABAY László, NÉMET János, PAPP Zoltán

[The circulatory changes and the characteristics of blood flow in certain uterine vessels can be detected by transvaginal color Doppler in early pregnancy. The uterine circulation of 53 patients with normal intrauterine pregnancies at 4–14 weeks of gestation and 104 non pregnant patients were investigated. The main uterine artery, arcuated and spiral arteries were demonstrated by color Doppler in all patients in early pregnancy and characteristic flow velocity waveforms were obtained in 94% of the cases. The impedance to flow in the main uterine artery was significantly lower and the mean velocity was significantly higher in early pregnancy than in non pregnant patients. The indices of impedance to flow decreased with gestation in the uterine branches and there was a progressive fall in these indices from the uterine artery to the spiral arteries. Mean blood velocity in the uterine artery increased with gestation. The hemodynamical changes which are proportional to gestation age give an indirect evidence of the adequate maternal blood supply for the growing embryo.]

[Health insurance chances]

FRENKL Róbert

[Every Hungarian citizen has the right to the highest quality of health care free of charge.This was the basic tenet of the socialist health care system, which, with its hypocrisy and lies, made all reform efforts hopeless from the start. Worse still, for successive generations of doctors, unreality became the defining feature, and the only protection against its demoralising effects was the closeness of a few worthy individuals, their professionalism and human decency. ]

[Echocardiographic judgment of the left ventricular remodelling and heart failure’s types]

HATI Krisztina

[The heart responds to the damage to the heart muscle with various changes that are regulated by complex processes. If the harm is irreversible, changes that begin as an adaptation can become chronic and permanently worsen heart function. The author details below the pathological remodelling of the left ventricle that can lead to heart failure. It covers the types of heart failure based on the latest recommendations and presents the echocardiographic examination methods that can be used to assess the diastolic, systolic and right ventricular function of the heart.]

[Non-invasive evaluation of cardiovascular risk in pediatric chronic kidney disease patients]

BÁRCZI Adrienn, DÉGI Arianna Amália, KIS Éva, REUSZ György

[Cardiovascular diseases are the leading cause of mortality and morbidity in children with chronic kidney disease (CKD). Similar to adults, children with CKD experience a high burden of traditional and uremia-associated risk factors. Recent years, several studies were published in connection with cardiovascular risk factors, patomechanism, and early markers of cardiovascular diseases. Early signs of cardiomyopathy, such as left ventricular hypertrophy or dysfunction, and markers of atherosclerosis, such as increased intima-media thickness of the carotid artery or increased wall stiffness of the aorta are frequently present in early stages of CKD in children. As prevention is important in pediatrics, the evaluation of subtle changes of the cardiovascular system provide opportunity for early treatment and that enables children to develop normally and have a better long-term quality of life. Recently, newer non-invasive cardiovascular imaging modalities have been emerged to diagnose subclinical alterations of the heart and vessels in this specific population with kidney disease. In this review, we provide an overwiev of the emerging imaging techniques used to detect early subclinical organ damage in pediatric chronic kidney disease patients.]

[Echocardiography in the management of acute myocardial infarction]

LENGYEL Mária

[The author presents a detailed review of the role of echocardiography (echo) in the management of acute myocardial infarction (AMI). The echo diagnosis of AMI is based on segmental wall thinning and akinesia with a 90% accuracy. Echo has made a major impact on the immediate diagnosis of mechanical complications in the hemodynamically compromised patient with AMI. These mechanical complications which include myocardial rupture of the free wall or the septum or the papillary muscle, may be successfully treated by prompt surgical intervention. Echo diagnosis has an important role in the management of other complications of the acute, subacute and chronic phases of infarction as well, such as pericardial effusion, left ventricular thrombus, left ventricular aneurysm and pseudoaneurysm. Therapeutic strategies are thoroughly affected by systolic and diastolic function assessed by echo. Echo has a basic role in the algorithm of postinfarction anticoagulant treatment. Besides rest echo, early stress echo has a definite prognostic value in predicting multivessel disease and identifying viable myocardium which requires revascularisation procedures. The indications for echo in the acute phase and before discharge are summarized according to recent American recommendations. ]

[ISOTOPE BASED CARDIAC DIAGNOSTICS - POSSIBILITIES IN NUCLEAR CARDIOLOGY]

BALOGH Ildikó

[Methods of nuclear cardiology have been applied for several decades and there is continuous development in this area. The most commonly used modality is the myocardial perfusion scintigraphy (MPS). During stress MPS, the presence and the severity of ischaemic heart disease (IHD) can be detected. Resting MPS can show a freshly developing acut myocardial infarction (AMI) immediately, but new and old infarcted myocardial areas can not be distinguished by this method. Using SPECT (single photon emission tomography) examination and quantitative analysis can improve the accuracy of MPS. With gated SPECT we can analyse both the perfusion and the function of left ventricle. To examine the function of left and right ventricle the “gold standard” non-invasive method is MUGA (multiple gated acquisition) of blood pool scintigraphy. After only a few hours of the onset of AMI we can detect it with the socalled infarct avid scintigraphy using radiopharmaceuticals which accumulate in affected area. Following an AMI it is essential to differentiate among high and low risk patients for revascularisation treatment, therefore distinguishing the viable (hibernating) and non-viable (necrotic) myocardium with imaging techniques is an important task. Preserved metabolism as the sign of viable myocardium can be detected both by SPECT (most accurately by thallium rest-redistribution scintigraphy) and PET (detecting glucose metabolism by F-18-FDG). Adrenerg receptor scintigraphy can show the sympathetic innervation: in the case of a transplanted heart it can detect the reinnervation and in the case of malignant ventricular tachyarrhythmias the risks and the severity of the illness.]

[The diagnostic value of a glass of soda water in case of a cardiac space-occupying lesion]

PÁLINKÁS Attila, CZAKÓ László, CSÁSZÁR Ildikó, NAGY Edit, SZABÓ Marianna

[INTRODUCTION - Large hiatal hernias may result in cardiac space-occupying lesions. Our case study discusses the clinical aspects and the possible diagnostic approaches for such large hiatal hernias that cause cardiac compression. CASE REPORT - In an elderly patient with no cardiovascular symptoms, transthoracic echocardiography revealed a left atrial space-occupying mass. The diagnosis regarding the origin of the cardial mass was clarified by a glass of soda water drunk by the patient during echocardiography, as it resulted in a decrease in the inhomogenous echodensity of the mass and the appearance of “contrast bubbles” within it. This phenomenon suggested the presence of a large hiatal hernia compressing the heart, which was confirmed by gastroscopy and upper gastrointestinal barium examination. CONCLUSION - Drinking soda water during transthoracic echocardiography can help to diagnose lesions that look like intracardial tumours.]
