Background Our objective was to evaluate the relationship between initial serum brain natriuretic peptide (BNP) levels and right ventricular functions in inferior myocardial infarction (MI) with and without right ventricular involvement. Methods The study included 61 patients, who presented with acute inferior MI. Twenty-seven patients had right ventricular involvement. Blood samples for BNP ...

BACKGROUND Coronary artery bypass graft surgery is a well-known and proven method of treatment for coronary artery disease. A modification of this method is complete revascularisation of the right ventricle by sequential bypass grafting of the right coronary artery, the effects of which on ventricular function need to be clarified. We sought to determine the effect of the sequential bypass gra...

background: cardiac rehabilitation has been recognized as one of the most effective strategies for managing cardiovascular indices as well as controlling the cardiovascular risk profile, in particular after coronary artery bypass graft surgery (cabg). however, the effect of this program on right ventricular function following cabg is unclear. the aim of this study was to evaluate the impact of ...

INTRODUCTION Conventional, atrial-synchronised, right ventricular apical pacing (VP) may compromise ventricular function by causing ventricular desynchronisation. The aim of this study was to evaluate the long-term effects of VP on left and right ventricular systolic and diastolic function. METHODS We studied 21 clinically stable dual-chamber pacemaker recipients (mean age 68 +/- 9 years) wit...

Right ventricular (RV) diastolic dysfunction is an important indicator for the assessment of heart failure. Abnormalities in RV diastolic function underlie many pathologies. However, the underlying mechanisms remain poorly described, because the term is used to describe many variants in diastolic pathophysiology and function. Since the right ventricle is coupled to the pulmonary circulation wit...

BACKGROUND Obesity is a major health problem in the Western world. Among obese subjects cardiac pathology is common, but conventional noninvasive imaging modalities are often suboptimal for detailed evaluation of cardiac structure and function. We investigated whether cardiovascular magnetic resonance imaging (CMR) can better characterize possible cardiac abnormalities associated with obesity, ...

artery occlusion caused no change in cardiac output, or right and left ventricular pressures, although right ventricular contractile force fell markedly. With right coronary artery flow intact, incremental pulmonary artery obstruction caused a corresponding decline in cardiac output and elevation of right ventricular end-diastolic pressure with eventual total right ventricular failure and syste...
