AbstractOne hundred-thirty patients with acute subarachnoid hemorrhages were investigated to examine the relationship of neurogenic pulmonary edema to cardiac lesions. Abnormal electrocardiograms were observed in 99 of these patients. Left ventricular asynergy was detected in nine of the 99 patients by two-dimensional (2D) echocardiography. In addition to 2D echocardiography, chest radiography, electrocardiography, serum CPK measurements and cardiac catheterization were performed for these nine patients in the acute stages of their subarachnoid hemorrhages. Abnormal electrocardiographic findings included prolongation of QT intervals and marked ST-T changes, which were observed in all nine patients. Pulmonary edema associated with increased pulmonary arterial wedge pressures were noted in seven, and increases in CPK and MB-CPK in all patients, suggesting the occurrence of myocardial necrosis. An increase in serum catecholamine was observed in all patients. Coronary angiography was performed in two patients and revealed normal coronary arteries in both. Biopsy findings were available in three and demonstrated severe fragmentation at the sites of left ventricular asynergy. Pulmonary edema, electrocardiographic abnormalities and left ventricular asynergy improved markedly during the courses of hospitalization. We concluded that left ventricular asynergy and myocardial necrosis may occur during the acute stage of subarachnoid hemorrhage and could produce neurogenic pulmonary edema rather than or in addition to permeability edema.
