Insights
Depression is common in patients with chronic heart failure (CHF). This study found that 30% of CHF patients experienced depression, with severe cases being more frequent than mild ones.
Area of Science:
- Cardiology
- Psychiatry
- Public Health
Background:
- Heart failure (HF) is a widespread condition with a poor prognosis.
- Depression occurs 4-5 times more frequently in HF patients than the general population.
- Depression may increase the risk of developing HF and worsen outcomes in existing HF patients.
Purpose of the Study:
- To determine the prevalence of depression in patients with chronic heart failure (CHF).
Main Methods:
- A descriptive, cross-sectional study was conducted in Peshawar from November 2011 to April 2012.
- 121 patients with chronic heart failure were assessed.
- Sample size was determined using WHO software, with a 13% expected depression proportion, 95% confidence level, and 6% margin of error.
Main Results:
- The average age of participants was 55 years, with 68% males and 32% females.
- 30% of patients with chronic heart failure presented with depression (HADS score > 11).
- Severe depression was more common than mild depression among the study population.
Conclusions:
- Depression is a significant issue among patients diagnosed with chronic heart failure.
- The findings highlight the need for mental health screening and support in cardiac care settings.
Unlabelled:
Heart failure is a prevalent debilitating disease of poor prognosis in which heart cannot fill with or eject the sufficient amount of blood that is required due to structural or functional cardiac disorder. Depression is 4-5 times as common in heart failure (HF) patients as in the general population, and it might confer a higher risk of developing HF and negatively affect prognosis in established HF.
Objective:
To determine the frequency of depression among patients presenting with chronic heart failure.
Methods:
This descriptive cross sectional study was conducted in cardiology department Hayat Abad Medical Complex Peshawar from November 2011 to April 2012. In this study a total of 121 patients were observed by using 13% proportion of depression in heart failure, 95% confidence level and 6% margin of error, under WHO software for sample size determination.
Results:
Mean age was 55 +/- 1.26 years. Sixty-eight percent patients were male and 32% were female. Fifteen percent patients had chronic heart failure for less than 1 year, 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. Thirty percent patients had depression in chronic heart failure while 70% did not have depression in heart failure.
Conclusion:
Depression is common among CHF patients. Severe depression is more frequent than mild depression.
