A comprehensive, quick-reference guide to the diagnosis and management of peripheral artery disease for non-specialists
With an aging population subject to an increasing number of health risks, peripheral artery disease (PAD) is on the rise throughout the world. Because of PAD’s direct links to heart attack and stroke, it is critical that internists, surgeons, cardiologists, radiologists, gerontologists, GPs, and family practitioners know how to recognize it and make the best treatment recommendations for their patients. This book provides all the expert, practical information and guidance they need to do just that.
Edited by two thought leaders in PAD diagnosis and treatment, and comprising chapters written by subject matter experts, Peripheral Artery Disease, Second Edition provides clinicians with guidance on how to diagnose and treat one of the most under-diagnosed conditions affecting millions of patients. This updated and revised edition of the popular guide distills the complexities of PAD into clear, actionable advice for busy medical practitioners, providing them with the information they need—when they need it.
Provides clinicians with essential information for recognizing and treating this under-diagnosed condition that affects millions of patients
Distills the complexities of PAD, from diagnosis to traditional and emerging treatment options, into clear, actionable advice for clinicians
Covers PAD epidemiology, office examination, imaging, laboratory evaluation, medical therapy, surgical interventions, endovascular treatments, and much more
Reflects the latest PAD Guidelines and Performance Measures established by leading specialty societies
Features contributions from internists and surgeons, all recognized experts in PAD
Peripheral Artery Disease, Second Edition is an important working reference for internists, cardiologists, radiologists, and surgeons, as well as fellows and residents in those fields.
