Researchers from the United States found an unusual correlation between the thinness of patients and their risk of death after hospital manipulations. Scientists said that thin people tend to die more often after treatment of heart pathologies than those who have a high body mass index.

Doctors from the Lenox Hill Hospital in New York studied the data on the state of a million (1,035,727) people who underwent cardiac catheterization-an invasive procedure that allows both diagnosis of heart problems and treatment procedures. In particular, experts were interested in how long such patients stayed in the hospital, how soon they got there again, and also the cases of death. These indicators were compared with the weight of patients and their BMI data.

Physicians managed to see an unusual pattern. It turned out that lean people were less likely than complete to have cardiac catheterization, as well as percutaneous coronary interventions. But at the same time, thin patients were more likely to die in those cases when they underwent these procedures.

"Compared to those who had a high BMI, participants with insufficient weight died three times more often. In general, they died five times more often than patients with obesity. People with very large BMI died less frequently than patients with normal weight, "the authors of the project.

Also, the researchers found that patients who were thin had more time to spend in hospitals - on average they were in clinics for 10.5 days, while patients with normal weight were discharged twice as fast.

The risk of re-hospitalization after coronary interventions in the skinny also turned out to be higher.

"The probability of re-entry into the clinic for 30 days in patients with underweight was increased by 18%. In patients with obesity, on the contrary, it was reduced by 8.2%, "experts said..
