SUrvey of Guideline Adherence for Treatment of Systolic Heart Failure in Real World

Study Overview
=================
Brief Summary
-----------------
The purpose of this study is to survey the guideline compliance of the cardiologists in the treatment of systolic heart failure in Korea

Detailed Description
-----------------
Major improvement in the medical management of CHF has been achieved in the past decades. But there is no doubt that prognosis of heart failure patients remains poor. The compliance to the standard treatment can be one of reasons. But very little data concerning this in Korea is available.
