Tumor necrosis factor-\u03b1 (TNF-\u03b1) is a cytokine produced in cardiac allografts and capable of producing hypertrophy and fibrosis; therefore, we suggest that TNF-\u03b1 may play a contributory role. Accordingly, the aims of our study were to define the role of systemic hypertension in the development of hypertrophy, characterize the histological determinants of hypertrophy, and characterize the expression of myocardial TNF-\u03b1 after heart transplantation.\n          <\/jats:p>\n          <jats:p>\n            <jats:bold>\n              <jats:italic>\n                <jats:bold>\n                  <jats:italic>Methods and Results<\/jats:italic>\n                <\/jats:bold>\n                \u2014\n              <\/jats:italic>\n            <\/jats:bold>\n            To separate the effect of hypertension from immune injury in the development of cardiac allograft hypertrophy, we measured the gain in left ventricular mass by 2D echocardiography in heart transplant recipients and lung transplant recipients who developed similar rates of systemic hypertension. The gain in left ventricular mass was 73% in heart transplant recipients and 7% in lung transplant recipients (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001). By comparing myocardial samples obtained during the first week after transplant and at 1 year, we found that there was a significant increase in total collagen content (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001), collagen I (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001), collagen III (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001), and myocyte size (\n            <jats:italic>P<\/jats:italic>\n            &lt;0.0001).
