n-terminal pro β-type natriuretic peptide (nt-probnp) is a valuable marker for monitoring the response to treatment in patients with heart failure. based on the clinically observed improvement of heart failure symptoms early after cardiac resynchronization therapy (crt), we sought to investigate whether crt induce any significant reduction in the plasma level of nt-probnp in three days after im...

discussion there are other causes of dilated cardiomyopathies which could be transient like peripartum cardiomyopathy. the development of biventricular mural thrombi is rare, and it mainly increases the risk of embolization in the systemic and pulmonary circulations. case presentation we present two case reports of post-myocardial infarction sequel leading to ischemic cardiomyopathy and peripar...

we investigated the vasodilatory effect of isoprenaline at large vessels (aorta, renal ans saphenous arteries, vena cava, renal and saphenous veins) in doxorbicin-induced model of heart failure. thirty saline-treated (normal group) and thirty doxorubicin treated rabbits (1 mg/kg administered intravenously twice weekly for 8 weeks) were studied after 16 weeks of treatment. chronic heart failure ...

background: cardiac resynchronization therapy (crt) is an effective treatment for patients with moderate to severe heart failure. however, 20-30% of patients remain non-responders to crt. we sought to identify which patients benefit the most from crt in regard to the etiology of heart failure. methods: eighty-three consecutive patients (62 men) who had a biventricular pacemaker inserted at tehr...

background: we sought to determine the frequency of the risk factors for congestive cardiac failure (ccf) in a tertiary care hospital in peshawar, pakistan. methods: this retrospective, observational study was conducted in the department of cardiology, postgraduate medical institute, lady reading hospital peshawar, from march 2005 to september 2007. relevant information regarding the risk facto...

introduction: cardiovascular abnormalities have been reported in liver cirrhosis (lc). in these patients, cardiac symptoms and physical signs occur as the liver functions worsen. cirrhosis is associated with hyper dynamic circulation and beta-adrenergic system changes responsible for the cardiovascular abnormalities. the purpose of the present study was to explore the echocardiographic findings...

background and objective: sleep-disordered breathing (sdb) is associated with increased morbidity and mortality in patients with heart failure (hf). we assessed the prevalence and the pattern of sdb in hf patients who were candidates for heart transplantation. materials and methods: twenty heart transplantation patients with ventricular ejection-fraction < 25% were recruited consecutively in a ...

we investigated neuronal uptake of noradrenaline (na) at the level of larger vessels (thoracic aorta and vena cava left renal artery and left renal vein lateral saphenous artery and lateral saphenous vein and finally central ear artery and marginal ear vein) in a model devised to mimic heart failure. the model presented here is the rabbit coronary ligation model in which myocardial infarction w...

although primary chronic hypertension (htn) is increasingly common in adolescence, secondary forms of htn are more common among children. primary htn is associated with being overweight and/or a positive family history of htn. carotid intima-media thickness, a known risk factor for atherosclerosis is frequent in both adults and children with htn and other associated cardiovascular (cv) risk fac...

background: sleep disorders are common among patients with chronic heart failure (hf), and it can have a significant effect on patients’ daily activities as well as their health. the purpose of this study was to assess sleep quality and its predictors in iranian patients with chronic hf.   methods : this cross-sectional study was conducted on a sample of 200 patients with hf in two hospitals of...
