Qatar is today one of the leading growing economies of the world and witnessing a population boom. It is currently undergoing major lifestyle changes, which comes with aplenty due to recently discovered vast natural resources. Enhanced knowledge of disease incidence/prevalence in the Qatari environment can have a prospect of developing and evaluating novel and more effective approaches for disease prevention, diagnosis and treatment in the future.

Detailed clinical history, followed by examination and laboratory tests were performed to identify the etiology and data analyzed to study the prevalence. Results: Our study revealed that in all cases of HF admitted in our hospital, 52% were males and 48% were females. The occurrence of Congestive Heart Failure (CHF) was highest between 50 and 80 years in both males and females. The relation of CHF to various etiologies has been discussed. The data has also been compared with select international studies and the variations discussed.
