Abstract
Cardiologists have gained considerable experience and expertise in the diagnosis and management of coronary artery disease. Interventional therapy has now become a standard cornerstone of therapy for coronary artery disease, and endoluminal stents are being used in over 70% of all coronary interventions. Diagnosis and treatment of peripheral arterial disease (PAD) has recently gained momentum. In the past, vascular surgeons and interventional radiologists were the classic caregivers for PAD patients, with an interest in deciding between intervention or no intervention. In addition, the majority of PAD patients had few medical resources since many medical specialists did not view PAD as important for many reasons, such as: (1) few effective options for the management of patients with PAD, (2) PAD did not represent a significant health hazard to patients, (3) few patients actually suffered from PAD, and (4) patients did not view PAD as a significant limitation in their quality of life. Over the past decade, a new medical specialty, vascular medicine, had dedicated itself to the comprehensive management of these complex patients. Vascular medicine specialists are predominantly internists and cardiologists. These physicians not only view PAD as an important medical issue, they understand the increasing prevalence of PAD among the "baby-boomer" generation, the shortened life-expectancy of patients with PAD, and the marked reduction in the quality of life among PAD patients. Most importantly, vascular medicine physicians are now aware of several effective options for patients with PAD.
