Introduction: Overweight is an important risk factor for cardiac dysfunction. Objective: To evaluate the relationship between body mass index and cardiac alterations in adults from north of Mato Grosso State. Methods: A cross-sectional study was carried out with 97 patients in a convenience sample at the cardiologic clinic in the city of Sinop / MT. Patients were divided into three groups: eutrophy (BMI= 18.5 to 24.9 kg/m²; n=23), overweight (BMI= 25.0 to 29.9 kg/m²; n=34) and obesity (BMI≥ 30 kg/m², n=40). The echocardiographic variables were compared between the three groups. Linear correlation and degree of independence were determined. The confidence level was 95%. Results: The body weight excess, especially obesity, was associated with heart remodeling and diastolic dysfunction. In addition, the obese group presented higher age and systolic blood pressure. All groups demonstrated adequate ejection fraction. Linear correlation between the body mass index and indicators of cardiac morphology was positive, however, negative for some markers of diastolic function. Conclusions: Body weight excess, especially obesity, was associated with cardiac remodeling and left ventricular diastolic dysfunction, which varied according to the body mass index.
