Obesity can result in heart disease risk, everyone is aware of it. However, these is new way to maintain the health of your heart. Weight loss surgery can decrease the risk of heart disease, a study says.

“This is the first large-scale analysis of predictors of change in cardiovascular disease risk factors among adolescents following bariatric surgery,” said Marc P Michalsky, Professor at the Ohio State University College in the US.

Findings

Three years after surgery, teens who underwent a gastric bypass had a 27 percent drop in their BMI, similar to the 26 percent drop in those who had the sleeve gastrectomy. Pixabay

  • Bariatric or weight-loss surgery performed during adolescence may provide unique benefits.
  • It minimizes the development and progression of impaired glucose metabolism, atherosclerosis heart failure and stroke.
  • Prior to the bariatric surgery, 33% of the participants had three or more defined cardiovascular disease risk factors.
  • Three years post-surgery, only 5% of the study participants had three or more risk factors; representing significant reduction in the overall likelihood of developing cardiovascular disease later in life.
  • Not only weight loss, the surgery also reduced dyslipidemia risk among teenager — a condition marked by an abnormally increased level of cholesterol in the blood, when compared to the older people.

Methodology

  • The study was conducted on 242 adolescents who were diagnosed with hearth risk factors at the baseline.
  • Among 242 participants of the study, 161 underwent Roux-en-Y gastric bypass procedure, 67 of them underwent a vertical sleeve gastrectomy and 14, adjustable gastric banding.
  • The authors collected data from five participating medical centers for their observational study, and decisions about procedures depended on each center’s clinical practices.
  • The participants had a BMI between 34 to 88 when the study began. A BMI over 25 is considered overweight; over 30 is obese.

Conclusion

  • The obesity classification with the highest risks of health problems is a BMI of 40 or higher. Three years after surgery, teens who underwent a gastric bypass had a 27 percent drop in their BMI, similar to the 26 percent drop in those who had the sleeve gastrectomy. Those with the gastric band had an 8 percent drop in BMI.

“The study demonstrated early improvement and reduction of cardio-metabolic risk factors, offering compelling support for bariatric surgery in adolescents,” Michalsky added.

The study was published in the online journal Pediatrics. (IANS)

Eat Vegetarian Diet to Ward Away Heart Disease

This is in contrast to the previous research that showed TMAO blood plasma levels -- and heart disease risk -- rise after the consumption of red meat and eggs, the researchers said

If you are suffering from high blood pressure, consuming fish, seafood and a primarily vegetarian diet may help reduce hypertension-related heart disease symptoms, a study suggests.

Intake of fish, seafood and vegetarian food increases levels of a compound called trimethylamine N-oxide (TMAO), known to boost heart health, said researchers from the Medical University of Warsaw in Poland.

The study showed that low-dose treatment with TMAO reduced heart thickening (cardiac fibrosis) and markers of heart failure in an animal model of hypertension.

“Our study provides new evidence for a potential beneficial effect of a moderate increase in plasma TMAO on pressure-overloaded heart,” the researchers said.

For the study, published in the American Journal of Physiology – Heart and Circulatory Physiology, researchers analysed the effect of TMAO on rats, which have a genetic tendency to develop high blood pressure.

One group of hypertensive rats were given low-dose TMAO supplements in their drinking water, and another group received plain water.

They were given the TMAO therapy for either 12 weeks or 56 weeks and were assessed for heart and kidney damage as well as high blood pressure.

The results showed that TMAO treatment did not affect the development of high blood pressure in any of the spontaneously hypertensive rats.

However, condition of the animals given the compound was better than expected, even after more than a year of low-dose TMAO treatment.

In addition, four- to five-fold increase in plasma TMAO does not exert negative effects on the circulatory system.

This is in contrast to the previous research that showed TMAO blood plasma levels — and heart disease risk — rise after the consumption of red meat and eggs, the researchers said.

“It seems that a fish-rich and vegetarian diet, is associated with a significantly higher plasma TMAO than red meat-and egg-rich diets, considered to increase the cardiovascular risk,” the researchers noted.

“However, further study is needed to assess the effect of TMAO and TMA on the circulatory system.” (IANS)
