title: Effect of systemic hypertension on renal function and left ventricular hypertrophy in heart transplant recipients.
abstract: To evaluate the incidence, risk factors and effects of systemic hypertension on renal function and left ventricular hypertrophy after cardiac transplantation, 85 transplant recipients on triple drug, low dosage, immunosuppressive therapy were studied. After a mean follow-up period of 12.5 +/- 8.7 months, a high incidence of hypertension was observed in 57 (67%) of the patients, and 42 (71%) of the 57 had developed new hypertension. None of the pretransplant and posttransplant cardiovascular risk factors were significantly associated with posttransplant hypertension. Faster deterioration of renal function, as assessed by intraindividual variations of serum creatinine values, was demonstrated in hypertensive patients and appeared as an early indicator of cyclosporine nephrotoxicity in patients at risk for hypertension. Serial echocardiographic evaluations demonstrated an early increase in left ventricular mass and fractional shortening in both hypertensive and normotensive heart transplant recipients. Fractional shortening further diminished significantly in normotensive patients but remained elevated in hypertensive patients, demonstrating sustained enhanced contractility in this group. Further studies will help to determine the exact relation between cyclosporine dosages and hypertension and their respective roles in the development of renal insufficiency and left ventricular hypertrophy after cardiac transplantation.
