More About This Title Management of Acute Coronary Syndromes
English
For each condition, the reader is taken through all of the therapeutic options available; in each case the indications and contraindications are evaluated in the light of the latest clinical trials. Potential complications are dealt with in a similar fashion, permitting the reader to anticipate and manage problems as they arise. The authors also present evidence-based recommendations for long-term care of at-risk patients, encompassing pharmacologic therapies and lifestyle management.
The book concludes with a comprehensive collection of appendices that include treatment algorithms, risk scores and a summary of the latest management guidelines.
Management of Acute Coronary Syndromes is the most up to date and comprehensive evidence-based guide to managing acute coronary syndromes, in a compact and usable format. It will be of interest to busy specialist physicians in cardiovascular medicine, cardiac and vascular surgery, and critical care, as well as primary care physicians and hospitalists who care for patients with these syndromes.
