According to a recent study by the American Heart Association, gaining just a small amount of weight can have a negative effect on heart physiology and make people more susceptible to heart failure later in life. The research was published in a recent issue of the Journal of the American Heart Association, which studied data from more than 1,200 patients who did not suffer from heart disease at the time they were surveyed.
The study found that those who gained even 5 percent of their body weight were at a higher risk of developing a larger left heart ventricle, which is a predictor of later heart failure. Those who lost weight saw the left ventricle get smaller. The study also found that a person’s weight at the start of the trial didn’t matter - weight gain showed ventricular enlargement, while weight loss showed ventricle reduction.
