Polyamines reduce heart injury caused by doxorubicin.

Isolated rat heart was perfused with 18 microM doxorubicin in the recirculating buffer. This treatment resulted in progressive contractile impairment. Aortic flow and minute work (i.e the product of cardiac output and peak systolic pressure) were reduced up to 20 and 29% of basal values, respectively. These parameters were partially restored in hearts perfused with 400 microM spermine, a naturally occurring polyamine, and 18 microM doxorubicin in the recirculating buffer. The results suggest the need for an investigation of the possible antagonistic role of polyamines against anthracycline cardiotoxicity.

Diagnostic pericardial window. A safe alternative to exploratory thoracotomy for suspected heart injuries.

During a five-year period, 104 patients underwent a pericardial window procedure to diagnose possible cardiac injury. Eighty-eight procedures were performed by a subxiphoid approach, and 16 were transdiaphragmatic in combination with an exploratory laparotomy. There were 51 patients with stab wounds, 45 with gunshot wounds, and eight with blunt trauma. All penetrating wounds were near the heart. In seven patients the window disclosed cardiac damage with no clinical signs of tamponade or shock. Fifty-one patients had signs of tamponade; however, only 12 of them had a cardiac injury diagnosed by pericardial window. Nineteen patients had cardiac injuries. One examination had false-negative results and one study had false-positive results. Cardiac wounds repaired included the right ventricle (eight), left ventricle (three), right atrium (five), and cardiac vein or pericardial wounds (three). Complications were negligible and consisted of minor wound infections (two) and postpericardiotomy syndromes (two). The pericardial window provides a rapid and safe means of diagnosing cardiac injuries in patients with equivocal signs of heart injury while sparing the patient without a heart wound a major operation.
