Left ventricular systolic dysfunction related to ventricular arrhythmias is a relatively poorly understood entity. To increase our knowledge base, we describe 5 patients in whom the link between ventricular dysfunction and ventricular arrhythmia was unequivocally established. All patients had repetitive monomorphic ventricular arrhythmias and left ventricular systolic dysfunction (ejection frac...

backgroundasthma is the most chronic inflammatory disorder of the airways in children and asthmatic patients can experience cardiac dysfunction, pulmonary hypertension and finally cor pulmonale later in life. we aimed to investigate right ventricular (rv) functions in asthmatic children by conventional and tissue doppler echocardiography (tde).materials and methods pulmonary function tests, con...

Besides its severe neurological injuries, spontaneous subarachnoid hemorrhage (SAH) commonly causes cardiac complications. These complications could include three different aspects of cardiac diseases, that is, electrocardiographic abnormalities, myocardial injuries, and left ventricular dysfunction. These complications not only may lead to misdiagnosis of SAH as myocardial infarction, but also...

Ethanol consumption is associated with left ventricular dysfunction in heavy ethanol drinkers. The effect of moderate ethanol intake on left ventricular function in hypertension, however, is unknown. We investigated the relationship between ethanol consumption and cardiac changes in nonalcoholic hypertensive patients. In 335 patients with primary hypertension, we assessed daily ethanol consumpt...

Background T1 mapping is increasingly employed for evaluation of diffuse fibrosis within the left ventricular (LV) myocardium. Physiological confounders require correction of raw data prior to analysis. T1 values have been inversely correlated with LV systolic and diastolic function. We sought to evaluate the feasibility of right ventricular (RV) T1 mapping and to assess its relationship with R...

BACKGROUND Heart failure and stroke are major causes of morbidity and mortality in older people. Angiotensin converting enzyme inhibitors improve symptoms and survival in left ventricular systolic dysfunction. Anticoagulants are effective in stroke prevention in atrial fibrillation with aspirin being a less effective alternative. OBJECTIVES To determine the prevalence of left ventricular syst...

Background Biventricular size and function have been studied extensively in patients after tetralogy of Fallot (TOF) repair, but little is known about atrial size and function. The atria play a crucial role in ventricular filling during diastole, and abnormalities in atrial size and function may reflect ventricular diastolic dysfunction. Diastolic dysfunction may precede systolic dysfunction an...

This study sought to investigate whether the presence of right ventricular systolic dysfunction with pre-existing left ventricular systolic dysfunction is associated with higher plasma brain natriuretic peptide (BNP) levels, compared with patients with isolated left ventricular dysfunction. Eighty-five patients referred for evaluation of isotopic ventricular function were prospectively included...
