Based on average blood pressure values, a strong direct relationship was found between arterial pressure and left ventricular hypertrophy, left ventricular chamber dilation (by echocardiography), and systolic dysfunction in patients undergoing dialysis for end-stage renal disease. After prolonged follow-up, blood pressures fell with the onset of congestive heart failure and manifest coronary artery disease. With the onset of cardiac failure, there appeared to be an inverse relationship between arterial pressure and mortality. From the outset, the strongest predictor of congestive heart failure was elevated blood pressure. (Adapted from Foley and coworkers [17].)
