Introduction: Heart failure (HF) is a clinical syndrome that occurs in patients who, because of an inherited or acquired abnormality of cardiac structure and or function, develop a constellation of clinical symptoms (dyspnea and fatigue) and signs (edema and rales) that lead to frequent hospitalizations, a poor quality of life, and a shortened life expectancy. UA is the final product of purine metabolism and hypoxic states cause an elevation of the serum UA level. Cell death, tissue hypoxia, and impaired metabolism in HF increase XO activity, leading to an overproduction of UA. Aim: To study correlation of uric acid levels with ejection fraction in heart failure patients (both acute & chronic). Materials and Methods: This is an observational study conducted at tertiary care Teaching Hospital over a period of 1 year. All patients who are admitted with symptoms and signs of Heart Failure in the wards like Intensive Care Unit, Acute Medical Care, Intensive Cardiac Care unit, Medical Wards, Cardiac Wards both paid and general rooms were recruited in the study. The sample size was 100 patients after evaluation by clinical and 2D echocardiography findings. Patients with signs and symptoms of Heart Failure and by satisfying inclusion and exclusion criteria were recruited. Results: A total of 100 patients with heart failure and ejection fraction less than 50 who presented to the department of general medicine. 26 male patients had ACS as the precipitating cause of heart failure compared to 29 female patients. In the present study the range of uric acid was observed between 7.1 – 10 mg/dl, the mean uric acid levels were observed to be 8.6 ± 0.67. In the present study, the range of Ejection fraction was observed between 28 – 48%, the mean ejection fraction was observed to be 34.8 ± 6.65. In the present study, it was observed that there was a significant and inverse correlation observed between uric acid levels and ejection fraction r = -0.808 p<0.001. Conclusions: The analysis of correlation conclusively proves that when serum uric acid is more than 7 mg / dl, then either RWMA or Global hypokinesia positive OR LVEF < 50 % in heart failure patients. The analysis also proves that serum uric acid levels are more in the severe functional disability patients (NYH III AND IV). This implies that Uric acid levels can be used as a marker for cardiac
