Study finds 'healthy' obese people more likely to develop heart failure than those of normal weight

Adults who are obese but appear healthy (without common metabolic abnormalities such as high blood pressure, abnormal blood fats, or diabetes) are not at greater risk of heart attack, stroke, or cardiovascular death than healthy individuals of normal weight, but they are around 33% more likely to develop heart failure and the heart rhythm condition, atrial fibrillation, according to a nationwide study from France that followed nearly 3 million hospital patients (aged 18 and older) for at least 5 years.
