Women Benefit More In Certain Heart Disease Treatment!

Posted May 31 2011 11:14am
Heart failure is a condition in which heart is unable to pump blood at an adequate rate or in adequate volume. In serious cases, heart failure patients could lose their life with cessation of heartbeat.

There are numerous reasons why one might develop heart failure, which can be sudden or happen gradually over a periods of time. Some common causes are heart attack, high blood pressure, defective valves in the heart, cardiomyopathies (diseases of the heart muscle), too much alcohol, and congenital conditions that one is born with.

Besides taking right mix of medications, heart failure patients could have their condition reversed if the heart valve is repaired or fast heart rhythm is controlled. In some cases, certain devices are used to help the heart beat and contract properly. For example, cardiac resynchronization therapy with defibrillator (CRT-D), which is a form of therapy for congestive heart failure caused by dilated cardiomyopathy, have been found to have remarkable benefits on appropriately selected patients with heart failure.

CRT-D can help guard against sudden death from irregular heart rhythm by using a specialized pacemaker to re-coordinate the action of the right and left ventricles in patients with heart failure. It can also help strengthen pumping action in patients with heart damage.
Researchers from the University of Rochester pointed out in their findings that CRT-D works twice as well in women. Their study, which was published on February 7, 2011 in the ‘Journal of the American College of Cardiology’, found that when using CRT-D, there was a 70 percent reduction in heart failure in women compared a 35 percent drop in men.
This is probably the first time in history of heart disease research that has credited a certain type of treatment that is more effective in women than in men. In the past cardiac studies, men and women generally received similar benefit from preventive medical therapy.
According to researchers, CRT-D works better in women because women tend to suffer from a different type of heart disease than men. The male participants in the study were more likely to have coronary heart disease while the female participants were more likely to suffer from non-ischemic heart disease.
Coronary artery disease, which is also known as ischemic heart disease, is a condition in which narrowed vessels restrict blood flow to the heart. Non-ischemic heart disease, on the other hand, is one that involves more generalized scarring of heart tissue.
