Long-Term Prognosis of Patients With Peripheral Arterial Disease: A Comparison in Patients With Coronary Artery Disease Gijs M. J. M. Welten, Olaf Schouten, Sanne E. Hoeks, Michel Chonchol, Radosav Vidakovic, Ron T. van Domburg, Jeroen J. Bax, Marc R. H. M. van Sambeek, Don Poldermans Peripheral arterial disease (PAD) is common in Western society, and the probability of developing PAD increases with age. It is considered to be an important risk factor for adverse late cardiac outcome. This large observational study compares the long-term prognosis of 2,730 PAD patients with a risk factor matched coronary artery disease population, using the propensity score of 2,730 patients who underwent coronary angioplasty but without PAD. Long-term prognosis is worse compared with coronary artery disease patients (hazard ratio 2.40, 95% CI 2.18 to 2.65). In addition, cardiovascular medication is significantly less prescribed in PAD patients.
