Arrhythmic Mitral Valve Prolapse: New Menaces of the Known Disease
Mitral valve prolapse (MVP) has long been the subject of intense discussions regarding the prognosis and follow-up tactics. In most cases, this condition has a benign prognosis. However, recent autopsy and follow-up studies have shown risks of developing sudden cardiac death (SCD) in some subgroups of patients who have this clinical phenomenon. The proposed literature review uses the population of patients with MVP with the highest probability of developing life-threatening ventricular tachyarrhythmias. Patients with the presence of a complex of changes, including bicuspid MVP, negative T waves in the inferior and lateral leads on a standard 12-lead electrocardiogram (ECG), and a special anatomical phenomenon called mitral annular disjunction (MAD), are at high risk of developing ventricular ectopias and VSS. A reflection of the high risk of SCD in such patients is the increase of ventricular ectopy according to Holter monitoring. The presence of a bicuspid MVP and the MAD phenomenon, which is a separation of the line of attachment of the posterior mitral leaflet from the basal inferior wall segment towards the atrial wall, determines the presence of a special form of MVP, the so-called arrhythmogenic MVP. Hence, in most cases MVP has a benign prognosis. However, patients with the aforementioned ar- rhythmic MVP signs must be given particular attention and annual follow-up including ECG control, Holter monitoring and echocardiographic examination of the heart to reduce the risk of ventricular tachyarrhythmias and SCD development
SAFETY OF AMIODARONE USAGE IN PATIENTS WITH WOLFF-PARKINSON-WHITE SYNDROME AND ATRIAL FIBRILLATION
Amiodarone is one of the basic antiarrhytmic drugs for atrial fibrillation treatment. However application of amiodarone in patients with atrial fibrillation and Wolff-Parkinson-White syndrome can induce ventricular fibrillation. Amiodarone usage in these patients should be accompanied by readiness for performance of resuscitation. This is confirmed by clinical case presentation
PROGNOSTIC VALUE OF PATHOLOGIC Q-WAVE AND TIME OF ITS APPEARANCE IN PATIENTS WITH MYOCARDIAL INFARCTION: COMPARISON STUDY
Aim. To evaluate short- and long-term prognosis of myocardial infarction (MI) depending on occurrence of pathologic Q-wave on ECG and time of its appearance.Material and methods. 616 patients with initial ST-elevated MI were included into the study — 254 women and 362 men, aged 62.1±11.2. All patients were split up three groups depending on occurrence of pathologic Q-wave on ECG and time of its appearance. First group consisted of 311 patients with early Q-wave (during first 6 hours from onset of MI symptoms). Second group consisted of 120 patients with late Q-wave (from 6 to 24 hours from onset of MI symptoms). Third group consisted of 185 patients with non-Q-wave MI.Results. The hospital lethality in the patients with early Q-wave was significantly higher than this in patients of the second and the third groups. However, we didn’t reveal significant differences between patients with late Q-wave and patients without Q-wave on ECG. The incidences of cardiac death (sudden death and fatal MI), non-fatal MI and hospitalization because of unstable angina was assessed during next two years. During the follow-up period patients of three groups had similar incidences of the non-fatal MI and hospitalization because of unstable angina. However, incidence of cardiac death was significantly higher in early Q-wave group in comparison with non-Q-wave group.Conclusion. Occurrence of pathologic Q-wave on ECG and time of its appearance should be taken into account to assessed short- and long-term prognosis of MI

DIAGNOSTICS AND TREATMENT OF MITRAL VALVE PROLAPSE
The mitral valve prolapse (MVP) is one of the most inconsistent diagnose. In the most cases patients with MVP have the good long-term prognosis, and therapy is aimed at reduction in psychovegetative dysfunction. Careful follow-up and timely cardiosurgical correction should be performed, if necessary, in patients with classical MPV. The choice method in these cases is the mitral valve plasty
EFFECT OF GENDER DIFFERENCES ON THE EFFICACY AND SAFETY OF REPERFUSION THERAPY OF ST-SEGMENT ELEVATION MYOCARDIAL INFARCTION (DATA OF RETROSPECTIVE SINGLE-CENTER STUDY – HOSPITAL PERIOD)
Gender differences can significantly affect mortality in ST-segment elevation myocardial infarction (STEMI) in real practice. Aim. To evaluate the effect of gender on mortality in STEMI. Material and methods. Outcomes of in-hospital stage of treatment of 553 men (67.7%) and 263 women (32.3%) were analyzed in single-center retrospective study. Primary percutaneous coronary intervention (pPCI) and pharmacoinvasive strategy (PIS) were used in 160 (60.8%) and 103 (39.2%) women, respectively, as well as in 295 (53.3%) and 258 (46.7%) men, respectively. Patients with time ″primary medical contact (PMC) – balloon″ less than 60 min and ″symptom - PMC″ more than 6 hours were excluded. The majority of patients were in a time interval ″PMC - balloon″ about 120 minutes. Results. Mortality in women was significantly higher than this in men regardless of the reperfusion strategy – 15.3% in whole (18.1% at pPCI and 10.9% at PIS), and 3.1% in whole (5.1% at pPCI and 0.8% at FIS), respectively (p<0.001). The probability of lethal outcome in women was 4 times higher than this in men (odds ratio 4.4; 95% confidence interval 2.7-7.1). Conclusion. Clinical characteristics of the patients due to gender differences make a significant contribution to the course of STEMI. Women more often have severe complications and a worse in-hospital prognosis
