title: The results of surgical treatment of left ventricular aneurysms. An assessment of the risk factors affecting early and late mortality.
abstract: The surgical results of left ventricular aneurysmectomy have been examined in 145 patients during a 13 year period. In 113 patients (78%) coronary artery bypass grafting (CABG) was also undertaken. There were 22 hospital deaths (15%) and 44 late deaths (30%). Stepwise, multiple regression analyses were used to examine many variables and to establish risk factors for hospital and late mortality. The chances of hospital death were increased by worsening New York Heart Association (NYHA) class, severe congestive heart failure (CHF), and extensive coronary disease. The risk of late mortality was increased by a significant right coronary artery stenosis and by poor contractility of the posterobasal segment. The probability of late death was reduced by a history of preoperative angina and an increasing number of grafts.
