Background: Oxidized low density lipoprotein (ox-LDL) and high-sensitive C-reactive protein (hs-CRP) are elevated in diabetes mellitus (DM) and associated with accelerated atherosclerosis. Little is known about their dynamics in the acute phase of ST segment elevation myocardial infarction (STEMI), especially in relation to the presence of DM and pre-diabetes (pre-DM). This study aimed to analyze timedependent changes in ox-LDL and hs-CRP regarding the presence of pre-DM and DM in STEMI patients treated by primary percutaneous coronary intervention (pPCI). Methods: In 103 consecutive patients with the first anterior STEMI ox-LDL and hs-CRP were measured before pPCI, on day 2 and day 7 after pPCI. Results: Patients were classified into: non-diabetics, pre-diabetics and diabetics. In each group the maximal ox-LDL concentration was found on admission, decreased on day 2 and reached the lowest values on day 7 (p<0.001). Diabetics had the highest ox-LDL concentrations compared to pre-diabetics and non-diabetics (on admission: p=0.028, on day 2: p=0.056, on day 7: p=0.004). hs-CRP concentration rose from admission, reached its peak on day 2 and decreased on day 7, in each group (p<0.001). Significant differences in hs-CRP concentrations were found between non-diabetics and pre-diabetics on admission (p=0.018) and day 2 (p=0.026). In a multivariate analysis DM was an independent determinant of high ox-LDL concentrations. Both ox-LDL and hs-CRP significantly correlated with Killip class, left ventricular ejection fraction, NT-proBNP and peak troponin I. Conclusions: In patients with the first STEMI treated by pPCI there were significant differences in ox-LDL and hs-CRP concentrations between non-diabetics, pre-diabetics and diabetics. Ox-LDL and hs-CRP concentrations were related to heart failure parameters. © by Danijela Trifunović 2015.

Introduction Congenital anomalies of the aortic arch, although numerous and heterogeneous, occur in less than 1% of individuals at autopsies. Left aortic arch with an aberrant right subclavian artery, also called arteria lusoria dextra, is the most common anomaly of the aortic arch, occurring in 0.5-2.5% of individuals. Case Outline We report the case of a 48-year-old man suffering from acute inferoposterior-wall ST elevation myocardial infarction successfully treated by primary percutaneous coronary intervention. Ten years ago, the patient had undergone coronary artery bypass graft surgery with the implantation of two arterial grafts - left and right internal mammary arteries on both left anterior descending and right coronary artery. After several attempts to canulate truncus brachiocephalicus, angiogram revealed the left aortic arch with the aberrant right subclavian artery. To our knowledge, this is the first described case of primary percutaneous coronary intervention via the aberrant right subclavian artery and right internal mammary artery graft with stent implantation in the infarct related lesion of the distal segment of right coronary artery. Subsequent 64-multidetector computed tomography confirmed the angiographic findings. Conclusion Early recognition of congenital anomalies of the aortic arch and its great vessels, even before coronary artery bypass graft surgery, could be crucial for the urgent and successful treatment of patients with life-threatening conditions, such as ST segment elevation myocardial infarction.

Background/Aim. Parathyroid hormone (PTH) is an important messenger in the regeneration process which might influence the outcome of patients with ST-segment elevation myocardial infarction (STEMI). The aim of this study was to investigate the role of PTH in comparison to other traditionally used markers for the prediction of heart failure in STEMI patients. Methods. In 165 consecutive patients with STEMI treated with primary percutaneous coronary intervention (PCI), blood concentrations of PTH, C-reactive protein (CRP), B-type natriuretic peptide (BNP), creatine kinase MB (CK-MB) and admission glycaemia (AG) were measured during the first three days after admission and correlated to the primary outcome episodes of acute heart failure in the period of six months. Results. The area under the ROC curve of the maximal serum concentration of PTH was the largest among the measured biomarkers (0.867 vs 0.835 vs 0.832 vs 0.627 vs 0.619, for PTH, CRP, BNP, CK-MB and AG, respectively) for the prediction of primary outcome. The maximal PTH level adjusted to several risk factors had an independent prediction value for primary outcome (p < 0.001). In addition, PTH improved the prediction of primary outcome when added to the other markers in the model [cstatistic with BNP, CRP, CK-MB and AG was 0.908 (95% CI 0.849–0.967)], and when PTH was added, it was 0.931 (0.883–0.980), with p < 0.001 for the discrimination. Conclusion. Serum concentration of PTH early in the course of STEMI can predict acute heart failure episodes in the first six months in patients treated with primary PCI. © 2017, Institut za Vojnomedicinske Naucne Informacije/Documentaciju.

Longer life duration, different clinical presentations of coronary disease, as well as high incidence of comorbidity in patients with ischemic heart disease have led to an increase in the incidence of ischemic heart failure. Despite numerous and new treatment methods that act on different pathophysiological mechanisms that cause heart failure, and whose aim is to slowdown or stop the progression of this devastating disease, morbidity and mortality in these patients remain high. These facts have firstly led to the introduction of the experimental, and then clinical studies with the application of stem cells in patients with ischemic heart disease. Previous studies have shown that the application of stem cells is a feasible and safe method in patients with acute coronary syndrome, as well as in patients with chronic ischemic cardiomyopathy, but the efficacy of these methods in both of the abovementioned clinical syndromes has yet to be established. This review paper outlines the basic principles of treatment of ischemic heart disease with stem cells, as well as the experience and knowledge gained in previous clinical studies. © 2015, Serbia Medical Society.

Introduction Left ventricular aneurysm is one of the most significant complications of myocardial infarction and it is thought to develop in 5–10% of all patients with acute myocardial infarction. Case report A 50-year-old male patient with a history of chronic alcohol abuse and risk factors for coronary heart disease was treated twice in the regional hospital center because of heart failure. Initially, echocardiography was not performed. Three years later he was admitted to the Urgent Center with a chief complaint of chest pain. He was evaluated by echocardiography, which showed a scar affecting the inferior wall of the left ventricle with an aneurysm on its basal portion which contained a thrombus. The patient also underwent transesophageal echocardiography which confirmed that there was a rupture of the commissural chordae tendineae of the posterior mitral leaflet with severe regurgitation. In consideration of these findings, the patient was referred to undergo coronary angiography, which revealed single vessel coronary artery disease. The patient subsequently underwent cardiac surgery for mitral valve replacement with an artificial valve, along with repair of the left ventricular aneurysm. Conclusion With consideration of his history of alcohol abuse, our patient likely experienced a silent inferior-basal myocardial infarction complicated by the development of an aneurysm of the ventricular wall. Subacute bacterial endocarditis may have been a contributing factor leading to infarction and rupture of the mitral valve chordae tendineae, and causing symptoms of heart failure and chest pain in our patient. © 2017 The Czech Society of Cardiology
