A U. S. doctor advises that women entering menopause need to be aware of their increasing risk of heart disease.

Women need to know their symptoms of heart attack may differ from those of men, says Dr. Vera Rigolin of Northwestern Memorial Hospital in Chicago. Men often experience chest discomfort while women commonly may have other, more subtle symptoms -- such as fatigue, nausea, shortness of breath, jaw pain or abdominal discomfort.

Rigolin says in a statement," In some women, plaque can build in the smallest blood vessels called the micro vascular circulation. These blockages do not show up in an angiogram. In these cases, we often use magnetic resonance imaging with medication to visualize blood flow within the small blood vessels when other standard tests do not provide us answers."

Rigolin further adds that menopausal women can lower their risk of heart disease by adopting a healthy lifestyle.

She says," If you are a smoker, quit immediately and avoid secondhand smoke. Eat a diet rich in fruits and vegetables and exercise at least three times per week to maintain a healthy body weight." (With input from agencies)
