FREQUENCY OF DEPRESSION IN PATIENTS WITH CHRONIC HEART FAILURE
AbstractAbstract: Heart failure is a prevalent debilitating disease of poor prognosis in which heart cannotfill with or eject the sufficient amount of blood that is required due to structural or functionalcardiac disorder. Depression is 4–5 times as common in heart failure (HF) patients as in thegeneral population, and it might confer a higher risk of developing HF and negatively affectprognosis in established HF. Objective: To determine the frequency of depression among patientspresenting with chronic heart failure. Methods: This descriptive cross sectional study wasconducted in cardiology department Hayat Abad Medical Complex Peshawar from November2011 to April 2012. In this study a total of 121 patients were observed by using 13% proportion ofdepression in heart failure, 95% confidence level and 6% margin of error, under WHO softwarefor sample size determination. Results: Mean age was 55±1.26 years. Sixty-eight percent patientswere male and 32% were female. Fifteen percent patients had chronic heart failure for less than 1year, 37% had chronic heart failure for 2–3 years and 48% patients had chronic heart failure for 3–4 years. Seventy percent patients had HADS score <11 and 30% had HADS scored of >11. Thirtypercent patients had depression in chronic heart failure while 70% did not have depression in heartfailure. Conclusion: Depression is common among CHF patients. Severe depression is morefrequent than mild depression.Keywords: Depression, Congestive Heart failure, NYHA, HADS
