This study aimed to investigate the clinical indicators of myocardial injury induced by type 2 diabetes mellitus (T2DM). The study includes 23 patients with T2DM, also having myocardial injury, identified as the illness group (IG), and 46 T2DM patients, randomly assigned to the control group (CG). The IG was subdivided into the dysfunctional myocardial contraction group (DCG, n = 10; left ventr...

We sought to characterize the features of sickle cell cardiomyopathy and to identify causative mechanisms using comprehensive cardiac magnetic resonance, echocardiography, and arterial tonometry. We found that sickle cell cardiomyopathy is characterized by 4-chamber dilation, myocardial fibrosis, abnormal myocardial perfusion reserve, diastolic dysfunction, and only rarely myocardial iron overl...

BACKGROUND Cardiac dysfunction after brain death has been documented, but its mechanisms remain unclear. Myocardial ischemia has been suggested as a possible cause. The aim of the present study was to investigate the existence of an imbalance between myocardial oxygen delivery and demand as a possible cause of myocardial dysfunction in brain-dead pigs. METHODS AND RESULTS Interstitial myocard...

OBJECTIVE To evaluate the prevalence and significance of myocardial dysfunction in children with septic shock. STUDY DESIGN Thirty patients with septic shock were evaluated by transthoracic echocardiography within 24 hours of admission to a pediatric critical care unit. Transthoracic echocardiography evaluation included left ventricular (LV) size and function, mitral valve inflow velocities i...

PURPOSE Reversible myocardial dysfunction or myocardial stunning is frequently described in patients with episodes of acute coronary syndrome and has recently been reported in critically ill patients without ischaemic heart disease. This article presents a study and description of the possible existence of myocardial dysfunction in critically ill patients in our setting who present no acute epi...

Background: Diastolic dysfunction may be the earliest marker which leads to progressive cardiac failure. Thus importance of detecting diastolic using tissue doppler echocardiography helps in preventing progression patients symptomatic congestive failure Objectives: 1. To find prevalence post myocardial infarction 2. study association between left ventricular and variables such as smoking, Diabe...

INTRODUCTION Severe sepsis during pregnancy or in the postpartum period is a rare clinical event. In non obstetric surviving patients, the cardiovascular changes seen in sepsis and septic shock are fully reversible five to ten days after their onset. We report a case of septic myocardial dysfunction lasting longer than ten days. To the best of our knowledge, this is the first report of prolonge...

Septic shock, the most severe complication of sepsis, accounts for approximately 10% of all admissions to intensive care. Our understanding of its complex pathophysiology remains incomplete but clearly involves stimulation of the immune system with subsequent inflammation and microvascular dysfunction. Cardiovascular dysfunction is pronounced and characterized by elements of hypovolaemic, cytot...

Studies in vitro suggested that inflammatory cytokines could cause myocardial dysfunction. However, the detailed mechanism for the cytokine-induced myocardial dysfunction in vivo remains to be examined. We thus examined this point in our new canine model in vivo, in which microspheres with and without IL-1beta were injected into the left main coronary artery. Left ventricular ejection fraction ...

Myocardial ischemia/reperfusion injury affects not only the cardiomyocyte compartment but also all other cellular compartments, and the coronary circulation has a central role in it. Acute myocardial infarction most often arises from atherosclerotic plaque rupture/erosion with superimposed thrombosis (type 1 myocardial infarction). However, in the absence of coronary atherosclerosis, coronary v...
