Atrial fibrillation is an abnormal heart rhythm which leads to a rapid and irregular beating. New research says that big and obese woman have a greater risk of heart attack as compared to small women. Annika Rosengren from the University of Gothenburg, Sweden have studied the impact of body size on atrial fibrillation risk in women. 1 522 358 women with a first pregnancy aged 28 years on an average participated in the study.

Information about weight of the women before pregnancy, their height, age, diabetes and smoking was collected from the Swedish Medical Birth Registry. Information on hospitalization with atrial fibrillation was collected from the Swedish Impatient Registry. Body Surface Area (BSA) in m2 was calculated using the standard formula based on height and weight. Women were classified into 4 categories on basis of BSA calculated.

The result was declared by Rosengren in which she said that obese women are at greater risk of atrial fibrillation. As the body size increases the risk of atrial fibrillation increases. The group of women with higher BSA had nearly three times the risk as those with the lowest BSA. The women having highest BSA were 9 cm taller, 28 kg heavier with higher body mass index of 21 kg/m2. High blood pressure and valvular heart disease are the most familiar alterable risk factors for Atrial fibrillation.

In younger women, we need not worry about the risk of atrial fibrillation, whatever may be their body size but in the case of older and aged women, they are at high risk of atrial fibrillation if their body size increases, she further added. Big people, not necessarily they have to be fat but with a larger atrium have a high risk of atrial fibrillation. Being tall have more advantages because tall people have less risk of stroke and heart attack and can survive longer, she continued.
