Beating Heart Differs by Gender, Age: Study
Date:12/8/2009

New imaging techniques could lead to better diagnoses, experts say

TUESDAY, Dec. 8 (HealthDay News) -- The human heart twists and turns as it beats, and a German study shows how the twisting and turning differs between men and women, and young and old.

In the study, published in the Dec. 8 online edition of Circulation: Cardiovascular Imaging, researchers at University Hospital Freiburg describe the different heartbeats they saw in 29 men and 29 women, all healthy, using an advanced imaging technology called MRI tissue phase mapping. The participants ranged in age from 20 to 60-plus.

The healthy heart doesn't just contract as it pumps blood. The base of the left ventricle, the chamber that pumps blood to the body, changes its direction of rotation up to six times for each beat.

"The left ventricle doesn't just shorten or get narrower," said Dr. Thomas C. Gerber, associate professor of medicine and radiology at the Mayo Clinic in Jacksonville, Fla. "It really twists like a dishrag, a very effective way of getting the blood out."

Clear differences by age and gender emerged from the study, the report said. Among them:

  • The rotation speed of the apex of the heart decreases with age.
  • Younger women have higher up-and-down motion velocities along the long axis of the ventricle than younger men, but those differences were reversed in older men and women.
  • Compared to men, women demonstrated reduced twisting of the ventricle, apex rotation and muscle velocity toward the center of the left ventricle during contraction.

The study could lead to the use of such coronary imaging in diagnosing heart problems, cardiologists say.

"To understand what is abnormal, we have to understand what is normal, and that can differ by gender and age," said Gerber. Full knowledge of those normal differences could help physicians understand "which abnormalities cor
