Subarachnoid hemorrhage (SAH) has been associated with cardiac injury and left ventricular (LV) dysfunction. The incidence natural history of neurocardiogenic after SAH remains poorly understood. objective this study was to describe the incidence, time course, recovery rate, segmental patterns LV dysfunction SAH.Echocardiography performed three times over a 7-day period in 173 patients SAH. global (ejection fraction [EF] < 50%) (any regional wall-motion abnormality [RWMA]) measured. course determined by comparing prevalence LVEF less than 50% RWMA at 0 2, 3 5, 6 8 days rate defined as proportion partial or complete normalization function. distribution RWMAs among 16 segments also determined. An found 15% patients, 13% had an normal LVEF. There trend toward increased 2 SAH, compared Recovery function observed 66% patients. most frequently abnormal were basal middle portions anteroseptal anterior walls. apex rarely affected.Left systolic occurs usually improves time. often do not correlate coronary artery distributions.
