Some patients with sarcoidosis can have cardiac involvement. Impairment of the cardiac sympathetic nerve activity is seen in about 50% of the sarcoidosis patients with small fiber neuropathy. In this case we present a sarcoidosis patient with small fiber neuropathy and cardiac symptoms with a cardiac sympathetic dysfunction, assessed with I-123 MIBG SPECT. After 5 months of treatment with carve...

cardiotoxicity is one of the most important adverse event related to anthracycline therapy and can lead in about 1-5% of cases to the occurrence of heart failure. in a higher percentage of patients treated with these drugs asymptomatic left ventricular dysfunction can occur, so that guidelines recommend a strict clinical and echocardiographic monitoring. however, the occurrence of left ventricu...

Background: The purpose of this study was to investigate efficacy of high dose vitamin D in improving left ventricular ejection fraction (LVEF) in thalassemia patients with heart failure and vitamin D deficiency. Materials and Methods: This clinical trial study was conducted on 16 chronically transfused thalassemia patients and ventricular dysfunction with vitamin D deficiency between December...

acute renal failure (arf) following cardiac surgery occurs in 1 to 10% of patients. patients who develop arf have higher rates of mortality. this study was undertaken to estimate the role of perioperative variables in predicting of post cardiac surgery arf. we studied a cohort of 398 adult patients who underwent cardiac surgery at our institution from february 2004 to february 2006. adult patie...

Excessive consumption of western diet (WD) induces obesity, resulting in cardiac dysfunction. Voluntary exercise ameliorates WD-induced obesity, but its effect on cardiac dysfunction remains unclear. Recent evidence suggests that elevated trimethylamine N-oxide (TMAO), a gut microbe-derived metabolite, can impair cardiac function in WD-induced obesity. We hypothesized that cardiac dysfunction i...

Leukotriene B4 (LTB4)-mediated leukocyte recruitment and inflammatory cytokine production make crucial contributions to chronic inflammation and sepsis; however, the role of LTB4 in lipopolysaccharide (LPS)-induced cardiac dysfunction remains unclear. Therefore, the present study addressed this issue using an LTB4 receptor 1 (BLT1) inhibitor. Administration of LPS to mice resulted in decreased ...

incidence of heart failure dramatically increases with aging. An important feature of cardiac aging is an increase in susceptibility to stress, such as ischemia and hemodynamic overload [1]. The heart is an organ in which mitochondria are abundant and mitochondrial dysfunction caused by oxidative stress is believed to be an important cause of aging and failure. Mitochondrial permeability transi...

  Inroduction: Heart failure (HF) is an important cause of morbidity and mortality in the cases of Beta-thalassemia major. The purpose of this study was to estimate HF prevalence in these patients and to assess the survivability of those who were treated with intensive chelating therapy.   Design and methods: This cross sectional study included 72 beta-thalassemia major cases, the mean age at t...

Oxygen sensor prolyl hydroxylases (PHDs) play important roles in the regulation of HIF-α and cell metabolisms. This study was designed to investigate the direct role of PHD2 in high fat-diet (HFD)-induced cardiac dysfunction. In HFD fed mice, PHD2 expression was increased without significant changes in PHD1 and PHD3 levels in the heart. This was accompanied by a significant upregulation of myel...
