Weight Loss Surgery May Repair Stressed Heart

Obesity is a risk factor for many types of heart problems, including atrial fibrillation, and cardiovascular disease leading to heart attack or stroke. Obese people often have signs of structural changes to the heart, including excess muscle mass in the left ventricle and enlargement of the right ventricular cavity – both conditions linked to heart failure. A new study which followed 400 patients after gastric bypass surgery finds that, with weight loss, the heart appeared to “remodel” itself, reducing the excess mass and decreasing the size of the ventricular cavity, thus decreasing the stress on the heart. The participants also had lowered blood pressure and heart rate and improved cholesterol levels, also decreasing the risk of a cardiovascular issue.
