Being bighearted can be a good thing--unless excess pounds are the cause. Risk of a ballooning heart wall and related irregular beats was 50% higher in obese people compared with those at a normal, healthy weight in a 14-year study of 5,300 by Harvard researchers. Obesity may cause the heart's upper left chamber, the atrium, to stretch out and develop a too-rapid beat that's out of sync with the rest of the heart, the scientists say. The condition, called atrial fibrillation (AF), raises stroke risk by four times and doubles the risk of death.
We keep learning more ways in which women's risk of heart disease is different from men's. A recent report indicating that atrial fibrillation, a condition in which the upper chambers of the heart quiver rather than contract, has provided a new lesson. According to data from the Framingham Heart Study, an ongoing project involving more than 5,000 people, atrial fibrillation is associated with a higher risk of death for women than for men.
Reports the findings of a Harvard study showing that regular consumption of fish containing omega-3 fatty acids reduces the risk of atrial fibrillation. Risk factors of atrial fibrillation, the m...
The article presents information on a seven-year study which revealed that women with diabetes are more likely to develop atrial fibrillation than men with diabetes.
