Dr. Marie-Eve Piché, the study author from the Quebec Heart and Lung Institute in Canada said: “Bariatric surgery was conceived for weight loss; our study indicates it may also reverse subclinical heart dysfunction. Since this abnormality predicts adverse cardiovascular events and mortality, its reversal could translate into improved prognosis.”

As obese people have higher risk of cardiovascular diseases; this risk is accelerated exponentially with the number of comorbidities that exists alongside obesity—namely type 2 diabetes, hypertension, and dyslipidaemia. Obesity and its co-occurring comorbidities affect cardiac arrangement and its function before the blatant heart disease befalls –a subclinical heart disease, which is said to be detected with cardiac imaging.
This study was conducted to examine the effects of bariatric surgery on heart disease. The study was also carried out to extract the impact of bariatric surgery on diabetes, hypertension, and dyslipidaemia.

It included 38 obese patients who were put through bariatric surgery. It also included 19 other patients matched for age and sex but was on the waiting list for the surgery. The patients were measured before bariatric surgery after and till six months in the row. The study was not only limited to body measurements, but also recorded the body weight, blood pressure, blood glucose, and blood lipids.

By those six months of medical probation, patients involved in the surgery group were found to lose 26% of their total body weight while the patients who were on the weight list for surgery had the same weight. Surprisingly, rates of comorbidities at six months were lower significantly in the surgery group as compared to those in the waiting list group: 13% versus 40% had type 2 diabetes, 5% versus 42% had dyslipidaemia, and 30% versus 61% had hypertension. The results were in the same line as boss shred program.

Around 22 patients (58%) involved in the surgery group were having subclinical heart disease in the beginning of the study. It was found that 82% of those patients, subclinical heart function had regularized at six months after surgery. On the contrary, subclinical disease got worse in 53% of patients on the waiting list during that six months period.

Furthermore in the surgery group, evidence of improved subclinical heart condition was achieved by comparing with 18-age-and-sex-matched hale and hearty weight controls. Prior to surgery, obese people suffered worse subclinical heart condition than healthy weight controls. During the period of six months, obese patients were similar in both the groups.

Quick Tip: Surgeries like bariatric can be expensive, to be healthy one need to lose weight, hence choose weight loss programs like boss shred program.

Dr. Marie-Eve Piché said: “We show that abnormal subclinical heart function in obese patients is common. Early (six months) after bariatric surgery, it normalizes in more than 80% of patients and is comparable to normal weight controls.”

“Obesity-related comorbidities also get better,” she further added. “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 myocardial function during follow-up.”

Additionally, Dr. Marie-Eve Piché said: “Bariatric surgery is an effective approach for weight loss. Our study suggests it has additional benefits on subclinical heart function, type 2 diabetes, hypertension, and dyslipidaemia. Longitudinal studies are needed to show if these changes reduce cardiovascular disease.”
