Aims To evaluate whether pulse pressure alone or with placental growth factor as estimates of arterial stiffness and endothelial dysfunction, predicts mortality, cardiovascular disease and progression to end-stage renal disease in patients with Type 1 diabetes. Methods Prospective, observational study, median (range) follow-up 8 (0-13)years, 900 patients with Type 1 diabetes, 458 with diabetic nephropathy, mean±SD age 44±11years. Results During follow-up, we recorded 178 (20%) all-cause deaths, 109 (12%) cardiovascular deaths, 213 (24%) cardiovascular events and 73 (16%) progressed to end-stage renal disease. Elevated pulse pressure predicted all-cause and cardiovascular mortality and cardiovascular events [Hazard Ratio (HR) (95% CI) per 10mmHg increase]: HR 1.2 (1.1-1.3), 1.3 (1.2-1.5) and 1.2 (1.1-1.3), P<0.001 (adjusted for sex, age, HbA 1c, cholesterol, diastolic blood pressure, creatinine, smoking, previous cardiovascular disease and nephropathy status). Furthermore, pulse pressure predicted the development of end-stage renal disease in patients with diabetic nephropathy: HR 1.2 (1.1-1.4), P=0.011 (adjusted for sex, age, HbA 1c, cholesterol, diastolic blood pressure, previous cardiovascular disease and glomerular filtration rate). In a two-hit model, patients with pulse pressure and placental growth factor levels above the median vs. below the median had increased risk of all-cause and cardiovascular mortality, cardiovascular events and progression to end-stage renal disease: adjusted HRs 2.3 (1.2-4.2), 4.2 (1.6-11.0), 2.3 (1.3-4.1) and 3.5 (1.0-11.8),P<0.05. Conclusions Elevated pulse pressure independently predicts mortality, cardiovascular events and progression to end-stage renal disease in patients with Type 1 diabetes. Placental growth factor adds to the predictive value of pulse pressure on cardiovascular and renal outcome.
