At the start of the study, 58% of patients in the surgery group had subclinical heart disease — which means changes to the heart and its function before actual heart disease starts. In 82% of those patients, subclinical heart dysfunction normalized six months after surgery.
But subclinical heart disease worsened in 53% of patients on the waiting list during the same period.
After six months of follow-up, the patients in the surgery group had lost 26% of their total body weight, while those on the waiting list stayed the same weight. Rates of obesity-related health problems in the surgery group were: high blood pressure, 30%; type 2 diabetes, 13%, and dyslipidemia (high cholesterol or triglycerides), 5%.
The findings were to be presented Thursday at the European Society of Cardiology annual meeting, in Vienna, Austria. Such research is considered preliminary until published in a peer-reviewed journal.
“We show that abnormal subclinical heart function in obese patients is common. Early [six months] after bariatric [weight-loss] surgery, it normalizes in more than 80% of patients and is comparable to normal weight controls,” said study author Dr. Marie-Eve Piche, from the Quebec Heart and Lung Institute.
“Obesity-related [problems] also got better,” she added in a meeting news release. “Interestingly, remission of type 2 diabetes after bariatric surgery was associated with improvement in subclinical heart function. Conversely, obese individuals with type 2 diabetes who remained on the surgical waiting list showed a worsening in their subclinical [heart] function during follow-up.”
