BACKGROUND: Pulse pressure (PP) values increase with age. The impact of PP on mortality in elderly patients has not been established. OBJECTIVES: To evaluate the effect of PP on mortality among very elderly hospitalized patients. DESIGN: A prospective clinical study. PARTICIPANTS AND MEASUREMENTS: The medical records of 420 inpatients aged>60 (187 males, mean age of 81.4±7 years) hospitalized in an acute geriatric ward were reviewed. Patients were followed up for amean of 3.46±1.87 years. Mortality data were extracted from death certificates. Using relative operating characteristic (ROC) curves, we identified PP of 62.5 mmHg as a cutoff point. Subjects were categorized as having low PP (≤62.5mmHg; N=116) or high PP (>62.5mmHg; N=304). MAIN RESULTS: The mortality rate was greater in patients with high PP than in those with low PP. During the follow-up, 201 patients died, 155 patients (51%) in the high PP group and 46 patients (39.7%) in the low PP group (p=0.038). Pulse pressure was associated with all-cause mortality (HR=1.69, 95% CI=1.19-2.38, p= 0.003) even after controlling for gender, age, diabetes mellitus, atrial fibrillation and heart rate. CONCLUSION: High PP is an independent predictor of mortality among elderly hospitalized patients.
