Influence of the internal-mammary-artery graft on 10-year survival and other cardiac events.

TLDR
It was found that patients who had only vein grafts had a 1.61 times greater risk of death throughout the 10 years, as compared with those who received an internal-mammary-artery graft.
Abstract
We compared patients who received an internal-mammary-artery graft to the anterior descending coronary artery alone or combined with one or more saphenous-vein grafts (n = 2306) with patients who had only saphenous-vein bypass grafts (n = 3625). The 10-year actuarial survival rate among the group receiving the internal-mammary-artery graft, as compared with the group who received the vein grafts (exclusive of hospital deaths), was 93.4 percent versus 88.0 percent (P = 0.05) for those with one-vessel disease; 90.0 percent versus 79.5 percent (P less than 0.0001) for those with two-vessel disease; and 82.6 percent versus 71.0 percent (P less than 0.0001) for those with three-vessel disease. After an adjustment for demographic and clinical differences by Cox multivariate analysis, we found that patients who had only vein grafts had a 1.61 times greater risk of death throughout the 10 years, as compared with those who received an internal-mammary-artery graft. In addition, patients who received only vein grafts had 1.41 times the risk of late myocardial infarction (P less than 0.0001), 1.25 times the risk of hospitalization for cardiac events (P less than 0.0001), 2.00 times the risk of cardiac reoperation (P less than 0.0001), and 1.27 times the risk of all late cardiac events (P less than 0.0001), as compared with patients who received internal-mammary-artery grafts. Internal-mammary-artery grafting for lesions of the anterior descending coronary artery is preferable whenever indicated and technically feasible.

A generalized Kruskal-Wallis test for comparing K samples subject to unequal patterns of censorship

TL;DR: In this article, a generalization of the Kruskal-Wallis test for testing the equality of K continuous distribution functions when observations are subject to arbitrary right censorship is proposed, where the distribution of the censoring variables is allowed to differ for different populations.

Long-term (5 to 12 years) serial studies of internal mammary artery and saphenous vein coronary bypass grafts.

TL;DR: Between 5 and 12 years after operation, the attrition rate of vein grafts greatly exceeded that of mammary artery grafts, and early vein graft patency was influenced by the coronary artery grafted and by angina.

The relation of risk factors to the development of atherosclerosis in saphenous-vein bypass grafts and the progression of disease in the native circulation. A study 10 years after aortocoronary bypass surgery.

TL;DR: The findings indicate that atherosclerosis in patients with saphenous-vein aortocoronary bypass surgery was a progressive disease, frequently affecting both the grafts and the native vessels, and that the course of such disease may be related to the plasma lipoprotein levels.
