Share shares In both sexes, the main heart chamber, the left ventricle - which fills with and then forces out blood - gets smaller with time. As a result, less blood enters the heart and less gets pumped out to the rest of the body.
But in men, the study reveals, the heart muscle that encircles the chamber grows bigger and thicker with age, while in women, it hpv treatment female retains its size or gets somewhat smaller.

A condition that affects more than five million Americans, heart failure is marked by the gradual 'floppiness' and weakening of the heart muscle and eventual hpv treatment female of hpv treatment female ability. To lower the risk, cardiologists often prescribe medications designed to reduce the thickness of the heart muscle over time and boost cardiovascular performance.
But the finding that in women, the heart muscle tends to shrink or remain the same size means they may not derive the same benefit from such treatments, hpv treatment female say. The research team cautions that its study was not designed to find what exactly fuels the differences in cardiac physiology between the sexes but says this 'fascinating discrepancy' demands further investigation to figure it out.
For the study, researchers analyzed MRI scans performed on nearly 3, older adults, ages 54 to 94, without preexisting heart disease. Participants were followed between andat six hospitals across the United States where each one of them underwent MRI testing at the beginning of the study and once more after a decade.
The MRI scans provided researchers with 3-D images of the heart's interior and exterior, allowing them to determine the size and volume of the heart muscle. Adding these to the already known density of the muscle, they were able to calculate its weight.
Over hpv treatment female period hpv treatment female 10 years, the weight of the heart's main pumping chamber -- the left ventricle -- increased by an average of 8 grams in men and decreased by 1. The heart's filling capacity, which is marked by the amount of blood the left ventricle can holds between heartbeats, declined in both sexes but more in women, by about 13 milliliters, compared with just under 10 milliliters in men. The differences in size, volume and pumping ability occurred independently of other risk factors known to affect heart muscle size and performance, including body weight, blood pressure, cholesterol levels, exercise levels and smoking.
