Lege Artis Medicinae - 2005;15(08-09)

[Cardiac resynchronisation therapy with biventricular pacing is a new treatment option in patients with moderate-to-advanced heart failure and left bundle branch block. Cardiac resynchronisation therapy leads to improved haemodynamics at diminished energy cost. Beneficial effects include reverse remodelling resulting in decreased heart size and ventricular volumes, improved ejection fraction and decreased functional mitral regurgitation. The haemodynamic improvements are associated with a significantly better quality of life, improved exercise tolerance and less frequent hospitalisation. Several randomised trials have evaluated the short- and longterm effect of biventricular pacing on haemodynamics and clinical parameters and recent preliminary data suggest that cardiac resynchronisation therapy can reduce the mortality. Despite major advances of lead and pacemaker techniques, the implantation of a biventricular pacemaker is still a challenging and complex procedure. To introduce the left ventricular pacing lead into the sinus coronarius may cause difficulties. Approximately one third of the patients do not respond to the therapy, therefore better pre-implant identification of the responders are needed. For patient selection and follow- up echocardiography has a major role.]

[MARITAL STRESS, DEPRESSIVE SYMPTOMS AND CARDIOVASCULAR VULNERABILITY IN WOMEN]

BALOG Piroska, MÉSZÁROS Eszter

[INTRODUCTION - Marital stress and depression have proved to be independent biopsychosocial risk factors for cardiovascular disorders. At the same time their interaction increases cardiovascular vulnerability. The Stockholm Female Coronary Risk Study has shown that marital stress was statistically significantly associated with depressive symptoms, in both groups of healthy women and in patients, even after adjusting for age, educational level, menopausal status, body mass index, cigarette smoking, sedentary lifestyle and the severity of heart failure. METHODS - The aim of this study was to investigate the effect of marital stress on depressive symptoms and psychosocial vulnerability in women with coronary heart disease and in healthy women, cohabiting and currently working. Data were obtained from the Hungarostudy 2002, representing the Hungarian population over the age of 18, according to age, sex and county. RESULTS - The results have shown that an increase in marital stress contributes to an increase in psychosocial vulnerability (depression, anxiety, vital exhaustion, sleep complaints) in healthy women and in women with cardiovascular disorders as well. Higher depression has been related with higher marital stress as well. DISCUSSION - The relation between marital stress and depression seems to be independent from socio-cultural, economical differences: the same results have been found in Hungarian and Swedish women. This relation seems to be bidirectional: a bad marriage increases the prevalence rate of depressive symptoms and depression worsens marital quality. At the end we propose a conceptual framework for how marital stress and depression increases cardiovascular vulnerability in women, emphasizing circular causality.]

[THE INFLUENCE OF GASTROESOPHAGEAL REFLUX DISEASE AND ITS TREATMENT ON ASTHMATIC COUGH]

BÖCSKEI Csaba, VICZIÁN Magdolna, BÖCSKEI Renáta, HORVÁTH Ildikó

[INTRODUCTION - Gastroesophageal reflux is known to cause chronic cough and it is also implicated in worsening of asthma. We conducted a prospective study to examine the clinical significance of gastroesophageal reflux disease in asthmatic patients with chronic cough, to analyse the temporal relationship between reflux events and coughing and to assess the effect of esomeprazole treatment on respiratory symptoms and lung function in these patients. PATIENTS AND METHODS - 126 asthmatic patients with chronic dry cough were studied. Diagnosis of gastroesophageal reflux disease was based on typical symptoms and the effectiveness of therapeutic test or on pH monitoring, while control group consisted of the patients without gastroesophageal reflux (negative pH results). The study group patients received the proton pump inhibitor esomeprazole (40 mg/day for three months) and standard treatment for asthma was continued. During the study pulmonary function tests (forced expiratory volume in one second and peak expiratory flow) were evaluated four times and the reflux symptom scores as well, using a questionnaire. RESULTS - The results of pH monitoring showed that 64% of cough episodes were related to acid reflux and in 91% of reflux events preceded coughing. Esomeprazole treatment (40 mg/day for three months) not only diminished gastroesophageal reflux symptoms but also improved asthma outcome measures. Baseline pulmonary function values increased significantly together with a decrease in symptom scores and the use of rescue medication. In most patients included in the extended part of the study for another three months, the dose of inhaled steroids could be reduced with sustained therapy against gastroesophageal reflux. CONCLUSION - Our data shows that reflux events preceded coughing in most cases and that treatment of gastroesophageal reflux disease caused an improvement in different outcome measures of asthma suggest that gastroesophageal reflux disease worsens asthma and its treatment is of clinical importance in the effective management of these patients.]

[TRAVEL MEDICINE IN GP PRACTICE]

KOVÁCS Erzsébet, FELKAI Péter

[The authors describe the basic ideas of travel medicine, as a newly introduced interdiscipline of the medical science in Hungary. Recently, this segment is considered to be the part of Insurance Medicine, on the other hand the methods and the practice of the travel medicine is based on the other medical specialities’ knowledge. Due to the growing number of travellers in our country as well as the consequences of the joining Hungary to EU, travel medicine could play an important role in the improvement of the Hungarian travellers’ attitude to their health care status, the prevention against the emerged infectious diseases, and in the medical assistance for the international tourism. Travel medicine also a good guideline for the fit-for-travel considerations, made by the GPs. Hungary with its advantageous geographical position appears to be an excellent stopover for any medical evacuation from East European or other surrounding countries. That is why we would like to establish a first travel medicine facility in central Europe. It is expectable that the Hungarian travellers require more and more information regarding to their health care possibilities and prevention during their trip. The first authentic person is being asked by the patients’ are GPs. The GP’s tasks are: diagnosis and the treatment of travel related diseases, the pre-travel advices. All the mentioned factors are a new challenge for the GPs in Hungary.]

[Benefits of SGLT-2 inhibitors: beyond glycemic control]

BALOGH Zoltán, SIRA Lívia

[In the recent years, according to international and Hungarian guidelines, in addition to lifestyle modification, metformin is the preferred initial glucose-lowering drug for most people with type 2 diabetes, if not contraindicated. Sodium glucose co­transporter-2 inhibitors have been shown to reduce progression of chronic kidney disease, or kidney failure, as well as the risk of hospitalizations for congestive heart failure and (mainly in secondary prevention) cardiovascular death in patients with type 2 diabetes. For major adverse cardiovascular events and for the renoprotection, there seems to be no class effect. On the other hand, a class effect of sodium glucose co­transporter-2 inhibitors is evident for hospitalization for heart failure. In this review the authors summarize novel data about sodium glucose cotransporter-2 inhibitors, and about their new perspectives in the near future.]

[DIURETICS IN CARDIOLOGY: PRESCRIBE OR USE?]

NAGY Viktor

[Diuretics are essential therapeutic tools. They effectively reduce blood pressure and have been shown in numerous hypertension clinical trials to reduce both cardiovascular and cerebrovascular morbidity and mortality. In addition, they are important components of the treatment of heart failure with apparent signs of congestion. While thiazides are recommended in mild forms, loop diuretics are used in the severe stages of congestive heart failure. Loop diuretics and thiazides often induce hypokalaemia, which has been demonstrated to be not as benign as thought before. Diuretic-induced hypokalaemia seems to be aldosterone dependent. Aldosterone levels increase during diuretic therapy. Aldosterone antagonists are unique among diuretics in that they improve survival of patients with heart failure independent of their effect on sodium metabolism. Because of this, diuretic treatment lives its renaissance in cardiology.]

[ELEVATED RESTING HEART RATE AND THE RISK OF CARDIOVASCULAR MORTALITY]

BORBOLA József

[In ancient times medical practitioners already knew that heart rate is a measure of the general condition of the soul and body. Worldwide epidemiologic studies in the past decades indicated that decreased resting heart rate, a parameter that can be simply measured, has a favourable direct effect on cardiovascular risk. This consistent beneficial risk-reducing effect can be clearly shown in the asymptomatic general population as well as in patients with hypertension, stable coronary artery disease, acute myocardial infarction and congestive heart failure irrespective of gender, age or ethnic origin. In the asymptomatic general population this beneficial effect is mainly due to reduced early coronary artery disease events and diminished risk of sudden cardiac death. Population studies have clearly shown that decreasing resting heart rate - either by physical exercise or medical treatment - improves cardiovascular survival, and decreases the overall and cardiovascular mortality. It seems reasonable to conclude that in modern pharmacotherapy of cardiovascular disease the use of selective heart rate lowering drugs that directly act on the pacemaker activity of the sinus node (If-channel blockers) are warranted.]
