Akutní ischemický iktus je katastrofické kardiovaskulární onemocnění s častými srdečními příčinami a mozkovými následky, a proto je k optimální léčbě a prevenci nutná úzká spolupráce mezi neurology a kardiology. Nedávné randomizované studie nadto prokázaly, že katetrizační trombektomie je nejúčinnější léčbou akutního iktu u správně vybraných nemocných. Intervenční kardiologie se svou 24hodinovou dostupností pro léčbu infarktu myokardu by mohla doplnit neuroradiologii v případech, v nichž není tento obor schopen poskytnout nepřetržitou dostupnost této moderní léčby pro nemocné s ikty. Je možné, že stojíme na prahu rozvoje nové medicínské subspecializace: neurokardiologie či kardioneurologie., Acute ischemic stroke is a catastrophic cardiovascular disease with frequent cardiac causes and cerebral consequences, thus the close cooperation between neurologists and cardiologists is necessary for the optimal patient management. Furthermore, recent randomized trials demonstrated, that catheter-based thrombectomy (CBT) is the most effective treatment for properly selected patients. Interventional cardiology with its widespread non-stop services for acute myocardial infarction can fill the existing gaps in coverage of population needs with neurointerventional services. Thus, a new future medical subspecialization may emerge: neurocardiology or cardioneurology., and Petr Widimský, Ivana Štětkářová

Our present focus on the hypoxic immature heart is driven by clinical urgency: cyanotic congenital cardiac malformations remain the single largest cause of mortality from congenital defects and ischemic heart disease is no more the disease of the fifth and older decades but its origin as well as risk factors are present already during early ontogeny. Moreover, the number of adult patients operated for cyanotic congenital heart disease during infancy steadily increases. This group approaches the age of the rising risk of serious cardiovascular diseases, particularly ischemic heart disease. Experimental results have clearly shown that the immature heart is significantly more tolerant to oxygen deficiency than the adult myocardium. However, the mechanisms of this difference have not yet been satisfactorily clarified; they are likely the result of developmental changes in cardiac energy metabolism, including mitochondrial function. The high resistance of the newborn heart cannot be further increased by ischemic preconditioning or adaptation to chronic hypoxia; these protective mechanisms appear only with decreasing tolerance during development. Resistance of the adult myocardium to acute oxygen deprivation may be significantly influenced by perinatal hypoxia. These results suggest that the developmental approach offers new possibilities in the studies of pathogenesis, prevention and therapy of critical cardiovascular diseases., B. Ošťádal ...

Kryptor system was proven to be a rapid, standard method for pregnancy-associated plasma protein A and proform eosinophilic major basic protein (PAPP-A/proMBP) complex detection in coronary artery disease (CAD). No age and/or gender differences in 51 controls and 110 stable coronary artery disease (SCAD) patients were found. SCAD patients did not differ from controls and no difference in PAPP-A/proMBP levels with regards to the number of affected vessels was found. In 21 unstable angina pectoris (UAP), in 35 without and 66 with ST elevation acute myocardial infarctions (NSTEMI, STEMI respectively) patients PAPP-A/proMBP levels were increased (P=0.004 and P<0.0005, respectively). PAPP-A/proMBP levels did not correlate with cardiac troponin I (cTnI) in STEMI and NSTEMI patients. PAPP-A/ proMBP increase was more frequent than cTnI (P=0.036) within the early phase of STEMI. In NSTEMI patients PAPP-A/proMBP positivity was present in 50 % of cTnI negative cases. Receiver operating characteristic (ROC) analysis revealed the highest diagnostic accuracy of PAPP-A/proMBP (0.919) in STEMI cTnI positive cases. The highest specificity/sensitivity PAPP-A/proMBP levels for particular acute coronary syndrome (ACS) types were 10.65-14.75 mIU/l. Combination of PAPP-A/proMBP with cTnI increases their diagnostic efficacy within the early phase of ACS. Our results suggest that PAPP-A/proMBP complex is involved in processes preceding vulnerable plaque development in ACS., P. Hájek, M. Macek, M. Hladíková, B. Houbová, D. Alan, V. Durdil, J.
