Prevalence of cardiovascular abnormalities in obese adults referred for bariatric weight loss surgery
Journal of Cardiovascular Magnetic Resonance volume 17, Article number: P188 (2015)
Obesity is associated with increased risk of death that may be related to underlying structural and functional changes in the heart. Cardiac MR (CMR) can provide detailed structural and functional information about the heart and vasculature that may improve our understanding of obesity related cardiac morbidity and mortality.
A cohort of 77 obese patients referred for stress CMR for evaluation of dyspnea prior to weight-loss surgery (WLS) were identified from our research registry. All patients underwent standard vasodilator stress perfusion protocol with late gadolinium enhancement (LGE) imaging on a 1.5T MR system. We collected demographic and CMR data including ventricular volumes, global and regional functional indices, and results of stress and LGE imaging. Comparison of CMR was made to previously derived and universally accepted normative data. The goal will be to assess these parameters 1 year post WLS and analyze the structural, functional and microvascular changes.
Please see table 1.
Multiple cardiovascular abnormalities are noted in severely obese patients including LV and RV dilation and microvascular ischemia that may contribute to the increased cardiovascular morbidity and mortality observed in this population.
