OBJECTIVE A retrospective cohort study was preformed aiming to verify the presence of transient dysfunction of gas exchange in the postoperative period of cardiac surgery and determine if this disorder is linked to cardiorespiratory events. METHODS We included 942 consecutive patients undergoing cardiac surgery and cardiac procedures who were referred to the Intensive Care Unit between June 2...
BACKGROUND Population-based estimates of cardiac dysfunction and clinical heart failure (HF) remain undefined among Hispanics/Latino adults. METHODS AND RESULTS Participants of Hispanic/Latino origin across the United States aged 45 to 74 years were enrolled into the Echocardiographic Study of Latinos (ECHO-SOL) and underwent a comprehensive echocardiography examination to define left ventric...
Hypertension induced by high-salt diet in Dahl salt-sensitive rats leads to compensatory cardiac hypertrophy by approximately 11 wk, cardiac dysfunction at approximately 17 wk, and death from cardiac dysfunction at approximately 21 wk. It is unclear what molecular hallmarks distinguish the compensatory hypertrophy from the decompensated cardiac dysfunction phase. Here we compared the gene expre...
Familial hypertrophic cardiomyopathy (FHC) has been linked to mutations in proteins of the cardiac contractile apparatus, including alpha-tropomyosin (Tm). Mice expressing alphaTm in the heart were developed to determine the effects of FHC mutant Tm on cardiac structure and function from single cardiac myocytes to whole organ function in vivo. Expression of E180G mutant Tm did not produce cardi...
Cardiovascular disease is the most common cause of death in diabetic patients. Hyperglycemia is the primary characteristic of diabetes and is associated with many complications. The role of hyperglycemia in the dysfunction of human cardiac progenitor cells that can regenerate damaged cardiac tissue has been investigated, but the exact mechanism underlying this association is not clear. Thus, we...
Sepsis-induced myocardial dysfunction represents a major cause of death in intensive care units. Dysregulated microRNAs (miR)-155 has been implicated in multiple cardiovascular diseases and miR-155 can be induced by lipopolysaccharide (LPS). However, the role of miR-155 in LPS-induced cardiac dysfunction is unclear. Septic cardiac dysfunction in mice was induced by intraperitoneal injection of ...
It has been recognized that changes in mitochondrial structure plays a key role in development of cardiac dysfunction, and autophagy has been shown to exert maintenance of mitochondrial homeostasis effects. Our previous study found that anti-β1-adrenergic receptor autoantibodies (β1-AABs) could lead to cardiac dysfunction along with abnormalities in mitochondrial structure. The present study te...
با گذراندن سوزن باریکی در غده لنفاوی قلب سگ که روش آن تحت عنوان clnc ذکرشده است (cannulation of cardiac lymph node) لنف بدست آمده با آنچه از راه رگ لنفاوی قلب بدست میاید و با عنوان clve نشان داده شده است (cardiac lymph vessel cannulation) از نظر مقدار پروتئین و جریان لنف مقایسه و مشاهده گردید که روش clnc ساده تر و بیشتر مقرون بموفقیت بوده و مقدار لنفاوی و پروتئین آن نیز با آنچه که توسط clvc بدس...
BACKGROUND AND PURPOSE Stroke can lead to cerebrogenic cardiac arrhythmias. We sought to investigate the effect of ischemic stroke on cardiac function in a mouse model of permanent middle cerebral artery occlusion (pMCAO). METHODS Twenty-four hours after the induction of focal ischemia, cardiac function was measured in mice by endovascular catheterization of the heart. Immediately after hemod...
idiopathic hypereosinophilic syndrome represents a heterogeneous group of leukoprolifrative disorders associated with prolonged eosinophilia of an undetectable cause with multi organ system dysfunction. it is a rare group disorder in children, most cases are reported in adult age group. we report a child with this syndrome who along with the usual features of the syndrome also had the presentat...
