Cardiovascular Function in Extreme Obesity
Key result
Extreme obesity was associated with adequate cardiac output adaptation to metabolic demands, but elevated ventricular filling pressures and vascular resistance suggested deleterious cardiovascular effects.

Implication
Alerts clinicians to possible elevated pressures in extreme obesity; extends cross-sectional data but requires longitudinal confirmation.

Outcome
Cardiovascular function assessed by electrocardiography (ECG), exercise test, determination of heart and blood volumes, and right heart catheterizationsurrogate
Extreme obesity is associated with elevated ventricular filling pressures and high systemic and pulmonary vascular resistance, suggesting deleterious effects on cardiovascular function despite adequate adaptation of cardiac output.
Cite This Study
Bäckman et al. (1973) conducted an observational in Extreme obesity (n=19). Cardiovascular function assessment was evaluated on Cardiovascular function (cardiac output, intravascular pressures, vascular resistance). Extreme obesity was associated with adequate cardiac output adaptation to metabolic demands, but elevated ventricular filling pressures and vascular resistance suggested deleterious cardiovascular effects.
