- Abstract
Diabet. Med. 29, 990-994 (2012) Abstract 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 ± 11 years. 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 10 mmHg 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, HbA1c, 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, HbA1c, 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.
