INTRODUCTION Electrocardiographic changes, troponin release, and reduced left ventricular ejection fraction have been described after subarachnoid hemorrhage (SAH). Little is known about the occurrence of diastolic dysfunction in this setting. The purpose of this study was to determine the prevalence of diastolic dysfunction and its association with cardiac(More)
BACKGROUND Left ventricular (LV) systolic dysfunction has been reported in humans with subarachnoid hemorrhage (SAH), and its underlying pathophysiology remains controversial. Possible mechanisms include myocardial ischemia versus excessive catecholamine release from sympathetic nerve terminals. METHODS AND RESULTS For 38 months, echocardiography and(More)
BACKGROUND AND PURPOSE Cardiac abnormalities occur commonly after subarachnoid hemorrhage (SAH) and may be caused by excessive release of catecholamines from the myocardial sympathetic nerves. We hypothesized that adrenoceptor polymorphisms resulting in greater catecholamine sensitivity would be associated with an increased risk of cardiac injury. METHODS(More)
OBJECTIVE Subarachnoid hemorrhage (SAH) is associated with cardiac injury and dysfunction. Whether aneurysm clipping versus coiling has a differential effect on the risk of troponin release and left ventricular (LV) dysfunction after SAH is unknown. It is hypothesized that aneurysm treatment does not affect the risk of developing cardiac injury and(More)
BACKGROUND AND PURPOSE Whether cardiac dysfunction contributes to morbidity and mortality after subarachnoid hemorrhage (SAH) remains controversial. The objective of this study was to test the hypothesis that cardiovascular abnormalities are independently related to in-patient mortality after SAH. METHODS This was a prospective cohort study of patients(More)
INTRODUCTION Abnormalities of serum sodium are common after subarachnoid hemorrhage (SAH) and have been linked to poor outcome. This study analyzed whether abnormal serum sodium levels are associated with cardiac outcomes and mortality after subarachnoid hemorrhage (SAH). METHODS In a prospective cohort study of SAH patients, the primary predictor(More)
BACKGROUND Elevated levels of B-type natriuretic peptide (BNP) have been associated with cardiac dysfunction and adverse neurological outcomes after subarachnoid hemorrhage (SAH). We sought to determine whether elevated levels of BNP are independently associated with radiographic cerebral infarction after SAH. METHODS Plasma BNP levels were measured after(More)
