Abstract

identification and prevention of HF. Therefore, this study aims to evaluate the prevalence of various stages of HF in individuals over 40 years old within a large population of Iranian adults.

Methods: In this descriptive cross-sectional study, a random sub sample of Yazd Health Study (YaHS) participants aged 40-70 years was evaluated. History and clinical examination of the patients was conducted by a cardiologist and then, the participants underwent echocardiography to determine the stages of heart failure.

Results: Among 410 Yazd population -the representative sample with mean age 58.0±9.2 years, 183 patients (44.6%) were in stage 0, 121 (29.5%) in stage A, 77(18.8%) in stage B, and 29 (7.1%) in stage C heart failure. No individuals were in stage D. There was a significant difference between the frequency of individuals with different stages of HF in terms of diabetes, hypertension, obesity, and history of ischemic heart disease (p<0.05). In addition, the frequency of HF increased in the age group >60 years and the obesity group (p<0.05).

Conclusion: According to these, about half of the patients with HF were in stage A and B. Therefore, appropriate measures are needed to identify these groups of patients, especially individuals with risk factors of diabetes, hypertension, obesity and those over 60 years to prevent the progression of the disease to higher stages which lead to poorer outcome.
