Positive and negative effects of trauma in patients after myocardial infarction : The role of type D personality

2020

Background: Experiencing a myocardial infarction threatens the health and life of the patient; therefore, it can be perceived as a traumatic event. Indeed, myocardial infarction may result in negative consequences, including symptoms of posttraumatic stress disorder (PTSD). However, it is also possible to experience positive effects from traumatic events, which is expressed as posttraumatic growth. Personality characteristics, including type D (i.e., distressed) personality, are among several factors that have been shown determine the occurrence of negative and positive consequences after exposure to trauma. Aim of the study: The aim of the present study was to establish the role of distres…

Immunoglobulin E (IgE) and ischemic heart disease. Which came first, the chicken or the egg?

2014

Several lines of evidence demonstrate that the immune system plays a pivotal role in development and progression of ischemic heart disease (IHD). More recently, a series of biological and clinical investigations has generated new interest about the existence of a relationship between a specific class of immunoglobulin, that is immunoglobulin E (IgE), and IHD. Data obtained in several epidemiological studies have convincingly demonstrated that the concentration of total serum IgEs is significantly increased in patients with IHD and often correlates with the prognosis. The putative mechanisms are essentially mediated by a physiological interaction between IgEs and mast cells, which triggers t…

Mesenchymal Stem Cells Provide Better Results Than Hematopoietic Precursors for the Treatment of Myocardial Infarction

2010

Objectives The purpose of this study was to compare the ability of human CD34(+) hematopoietic stem cells and bone marrow mesenchymal stem cells (MSC) to treat myocardial infarction (MI) in a model of permanent left descendent coronary artery (LDA) ligation in nude rats. Background Transplantation of human CD34(+) cells and MSC has been proved to be effective in treating MI, but no comparative studies have been performed to elucidate which treatment prevents left ventricular (LV) remodelling more efficiently. Methods Human bone marrow MSC or freshly isolated CD34(+) cells from umbilical cord blood were injected intramyocardially in infarcted nude rats. Cardiac function was analyzed by echoc…

Interaction of allopurinol with phenprocoumon in man.

1977

Conditions in two patients on long-term phenprocoumon (Marcumar®) treatment are reported who had signs of phenprocoumon overdosage when given simultaneously allopurinol. The determination of phenprocoumon plasma concentrations in one patient showed that phenprocoumon accumulates for several weeks during treatment with allopurinol. Signs of phenprocoumon overdosage thus can appear long time after starting allopurinol treatment.

Association between Serum Osteoprotegerin Levels and Severity of Coronary Artery Disease in Patients with Acute Myocardial Infarction

2021

International audience; Background. Osteoprotegerin (OPG), a glycoprotein of the tumour necrosis factor (TNF) superfamily, is one of the main biomarkers for vascular calcification. Aim. We aimed to evaluate the association between serum OPG levels and extent of coronary lesions in patients with acute myocardial infarction (MI). Methods. Consecutive patients hospitalized for an acute MI who underwent coronary angiography were included. SYNTAX score was calculated to assess the severity of coronary artery disease. The population was analysed in low (5 (3–6)), medium (11 (9–13)) and high (20 (18–23)) tertiles of SYNTAX score. Results. Among the 378 patients included, there was a gradual increa…

Plasma markers of platelet and polymorphonuclear leukocyte activation in young adults with acute myocardial infarction

2005

Our goal was to evaluate some plasma markers of platelet and polymorphonuclear leukocyte (PMN) activation in a group of young adults with acute myocardial infarction (AMI) at the initial stage and after three months. We enrolled 49 AMI subjects aged<45 years and examined plasmatic levels of platelet factor 4 (PF4), β-thromboglobulin (β-TG), elastase and myeloperoxidase (MPO) using ELISA methods. PF4 and β-TG were increased, compared to control subjects, both at the initial stage and after 3 months. In control subjects and in AMI patients, at both times of observation, there was a significant and positive correlation between the two platelet parameters, while no correlation was present betwe…

Stymulacja pęczka Hisa u osoby starszej z proksymalnym blokiem przedsionkowo-komorowym po zawale mięśnia sercowego

2018

Stymulacja pęczka Hisa (HBP) umożliwia synchronizację przedsionkowo-komorową i międzykomorową. W opisanym przypadku zwrócono uwagę na związek między poziomem bloku, synchronią komorową oraz funkcją rozkurczową u chorego z umiarkowaną dysfunkcją skurczową lewej komory świeżo po zawale serca. HBP jest korzystna w leczeniu zaburzeń przewodzenia i zapobieganiu dalszym zaburzeniom funkcji skurczowej i rozkurczowej. W artykule przedstawiono przypadek 92-letniego mężczyzny w bardzo dobrym stanie psychofizycznym z napadowym blokiem przedsionkowo-komorowym II stopnia i utrwalonym długim odstępem PR w przebiegu zawału mięśnia sercowego bez uniesienia odcinka ST-T, leczonego angioplastyką gałęzi okala…

The influence of severe mitral regurgitation on major adverse cardiac and cerebrovascular events after myocardial infarction in 1-year follow-up: Dat…

2023

Background: Mitral regurgitation (MR) is frequently observed in patients with myocardial infarction (MI). However, the incidence of severe MR in contemporary population is unknown. Aims: The study evaluates the prevalence and prognostic impact of severe MR in contemporary population of patients with ST-segment elevation myocardial infarction (STEMI) and non-ST-segment elevation myocardial infarction (NSTEMI). Methods: The study group consists of 8062 patients enrolled in the Polish Registry of Acute Coronary Syndromes over the years 2017‒2019. Only the patients with full echocardiography performed during the index hospitalization were eligible. Primary composite outcome was 12-month major a…
