Evaluation of underlying and precipitating cause of congestive heart failure

Background and Objectives: Heart failure is the end stage of cardiac disease after that myocardium has used all its reserve and compensatory mechanism. This is a descriptive survey for determine underlying and precipitating ethiology of congestive heart failure among patients who admitted on CCU and cardiac department of SAzar hospital of Gorgan. Materials and Methods: In this study 145 patients aged between 19-87 years have participated by data collection using questionair and analysis by SPSS-10. Results: The results indicated. The most common underlying causes is myocardial ischemia (57.3%) and the most common precipitating factors is inappropraite drug therapy (75.8%). Orthopnea (86.2%) and rails (82.8%) are the most symptoms and physical exam findings. AF rhythm with 24.1% is the most common arrythmia and cardiothorasic ratio more that 0.5 is the most abnormal finding in CXR-PA. The average ejection fraction (EF) in male patients was 32.3% and in women it was 35.7%. There was meaningful relationship between male sex and EF (P-value < 0.05). Conclusion: This study indicated that good control of HTN and preventing of (CAD) incidence are the most important factor to avoid from CHF and appropraite drug therapy has the essential role to maintain compensated state in heart failure.
