We carried out a systematic overview using individual patient data from the seven randomised trials that have compared a strategy of initial coronary artery bypass graft (CABG) surgery with one of initial medical therapy to assess the effects on mortality in patients with stable coronary heart disease (stable angina not severe enough to necessitate surgery(More)
The reliability of interpretation of coronary arteriography as a diagnostic tool was investigated in a sub-study of the VA Cooperative Study of Surgical Treatment for Coronary Arterial Occlusive Disease. Twenty-two physicians with varying levels of experience read 13 cine angiograms -- blind -- on two different occasions. Analysis of inter- and(More)
From a large cooperative prospective randomized study, data relating to a subgroup of 113 patients with angina pectoris and a significant lesion of the left main coronary artery were analyzed. Of these patients, 53 had been randomly allocated to a medical treatment group and 60 to a surgical treatment group. The former group received conventional medical(More)
The late results of renal transplantation are very encouraging. Apart from the more common complications, such as the rejection phenomenon and recurrent infections, occasionally renovascular hypertension may occur as a late complication. This is, to our knowledge, the first reported case of acute dissecting aortic aneurysm in a young man who had received a(More)
The development of esophagopleural fistula following pulmonary resection is an uncommon but serious complication. The fistula may appear either soon after operation, due to direct trauma to the esophagus or to its blood supply during extensive dissection, or later, in association with the development of a bronchopleural fistula and empyema following the(More)
Over the last 20 years, operative mortality has decreased and late survival has improved for patients with chronic stable angina who have coronary artery bypass surgery. However, this favorable trend may not continue because the operation is now extended to elderly and high-risk patients. The most powerful predictors of operative mortality include indexes(More)
Progression of coronary artery disease was evaluated after 5 years of follow-up in 119 medically and 109 surgically treated randomized patients who adhered to their assigned therapy. Progression was defined as the appearance of a new lesion (greater than or equal to 50% stenosis) or worsening of a preexisting lesion in a coronary artery. Progression(More)
This report presents the 42-month survival experience of 91 patients with a significant lesion of the left main coronary artery in the Veterans Administration Cooperative Study of Coronary Bypass Surgery. Survival in surgical patients was significantly better than that in the medical group (p = 0.016), even after adjustments were made for two important(More)
The incidence of endocarditis following open-heart operations is declining, but the relative incidence of endocarditis by the opportunistic organisms, both bacterial and fungal, has increased. These "opportunists" require careful identification and sensitivity testing so that appropriate therapy can be planned. In cases of candida endocarditis, a positive(More)
