Introduction: Obesity is considered an important public that presents increasing prevalence on a global scene. Obese individuals have greater susceptibility to the development of cardiac disease. Studies show that calcium (Ca2+) handling, essential mechanism in the process contraction-relaxation of the cardiac muscle, is associated with cardiac dysfunction in obesity models. While Ca2+ influx promotes elevation of free Ca2 + concentration in the cytosol in the contraction period, the recapture and extrusion Ca2 + are important to Ca2+ reduction during the relaxation. Objective: To identify, based on scientific literature, modulation of cardiac function by calcium handling impairments in models of genetic and dietetic obesity. Methods: The search for articles in electronic databases was performed with key words. Results: Initially studies that showed in title one of the key words were selected for analysis. 23 articles were obtained for reading in full. Then, 18 relevant articles were identified on cardiac dysfunction in obesity, both genetic and dietary and participation of the intracellular calcium handling. Conclusion: The literature presents that both genetic and dietetic obesity promotes cardiac dysfunction modulated by various changes in traffic intracellular Ca2+ and its regulators protein.Downloads
