Prevalence of myocardial infarction in congestive heart failure patient at emergency room of Rajavithi Hospital

Background: Congestive heart failure is a common condition and along with myocardial ischemia is a global public health problem. In the emergency room, myocardial infarction and uncontrolled hypertension are also found among patients who present with dyspnea from congestive heart failure. Therefore, the researchers chose to study the prevalence of acute myocardial infarction in congestive heart failure patients who presented at the emergency room of Rajavithi Hospital. Improving the screening of patients presenting at the emergency room with congestive heart failure will produce better treatment in the future. Objectives: To determine the prevalence of acute myocardial infarction and prevalence of preserved left ventricular function of patients who present at the emergency room of Rajavithi Hospital. Method: The study enrolled 91 heart failure patients who presented at the emergency room of Rajavithi Hospital from 1 July 2011 to 31August 2012. A cross-sectional descriptive study was conducted to determine the prevalence of acute myocardial infarction based on universal definition of myocardial infarction and prevalence of heart failure with preserved left ventricular function. The data were collected from medical records of patients. Statistics and data analysis included percentage, mean and standard deviation using the SPSS version 11.5
