Key result
Obesity significantly increased the risk of in-hospital mortality following acute type A aortic dissection repair compared to normal weight (17.4% vs 7.0%, OR 3.0).
Why the study?
Does obesity increase operative risk in Japanese male patients aged ≤59 years undergoing acute type A aortic dissection repair?
Observational (n=1,059)
Yes
Does obesity increase operative risk in Japanese male patients aged ≤59 years undergoing acute type A aortic dissection repair?
Obesity, but not overweight, appears to increase operative risk in young Japanese men undergoing acute type A aortic dissection repair.
The prevalence of obesity is increased among Japanese male patients with ATAAD aged ≤59 years. Obesity may increase these patients' operative risk; overweight does not.

Shimizu et al. (2020) conducted an observational in Acute type A aortic dissection (ATAAD) (n=1,059). Obesity (BMI ≥ 30 kg/m2) vs. Normal weight (BMI < 25 kg/m2) was evaluated on In-hospital mortality (OR 3.0, 95% CI 1.4-6.2, p=0.005). Obesity significantly increased the risk of in-hospital mortality following acute type A aortic dissection repair compared to normal weight (17.4% vs 7.0%, OR 3.0).
