BACKGROUND Right ventricular (RV) dysfunction frequently occurs and independently prognosticates in left-sided heart failure. It is not clear which RV afterload measure has the greatest impact on RV function and prognosis. We examined the determinants, prognostic role, and response to treatment of pulmonary arterial capacitance (PAC, ratio of stroke volume over pulmonary pulse pressure), in rel...

BACKGROUND Continuous-flow devices have become the standard of care for mechanical circulatory support for end-stage heart failure patients because of improved survival and durability. The effects of these devices, such as the HeartMate II (HMII) left ventricular assist device (LVAD), on right ventricular (RV) function have not been evaluated in detail. This study evaluated the incidence of RV ...

BACKGROUND Cardiac involvement in sarcoidosis is associated with a poor prognosis. In patients with right sided heart failure, differentiating between cor-pulmonale, or cardiac sarcoidosis has important implications to management. CASE PRESENTATION We present the case of a patient with severe but stable pulmonary sarcoidosis and new onset right sided heart failure despite only mild elevations...

Introduction: Breast cancer is becoming more frequently diagnosed at early stages with improved long-term outcomes. Radiation-related heart disease and lung cancer can occur following radiotherapy for breast cancer. The aim of this study was to evaluate some dosimetric parameters of heart and lung during whole breast radiotherapy. Materials and Methods: Twenty...

Although it is clear that cardiac norepinephrine stores are often markedly reduced in congestive heart failure, the mechanism responsible for this depletion has not been elucidated. The objective of this study was to investigate cardiac synthesis of norepinephrine in experimental right-sided heart failure by measuring the activity of tyrosine hydroxylase, the rate-limiting enzyme in the biosynt...

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...
