Women Benefit More In Certain Heart Disease Treatment!

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.

Is Distance Running A Dangerous Sport?

Taking part in a marathon is not easy and definitely not suitable for everyone because one needs to run for a distance of about 42 km. In October 2007, a 35-year-old police officer running in the Chicago Marathon collapsed and died. In Singapore, a 25-year-old army captain also died after finishing a half marathon in August 2007.

Does this mean that marathon is a dangerous sport? Before drawing any conclusion, let us hear what the experts have said about marathon.

In fact, statistics showed that sudden death during running a marathon is very rare. In Singapore, there is only one death in every 15,000 to 18,000 healthy runners each year. The more common one are ailments such as musculoskeletal and heat injuries, according to experts.

People with uncontrolled hypertension and ischemic heart disease should not take part in marathons. This is because unforeseen stresses from heat, dehydration and physical or psychological pressures could well strain the cardiovascular system. People suspected of other medical conditions should get a pre-race screen.

Once results of screening confirm one’s fitness for running marathon, he or she should then undergo adequate training. The runner should at least have completed a distance run of 30 to 32 km at some point during the training for a marathon. The purpose is to allow acclimatization to weather, testing the type of clothing need, knowing energy and fluid needs, and gauging body's limits.

Running for 42 km straight is very likely to wear out the body. The human body begins to experience fatigue as soon as the carbohydrate stores are depleted. Therefore, a high-carbohydrate meal should be taken before the big race to provided sufficient fluid and energy for a run. Meanwhile, do not try new food just before a race as this could cause gastrointestinal discomfort. Instead, opt for safe food choices such as bananas or power bars.

During the run, the runner should monitor his or her physical state because the day's temperature and humidity could also affect the body adversely. Under the hot weather, blood is diverted to the skin for heat dissipation. This, coupled with fluid loss from sweating, will affect the body's ability to deliver oxygen and energy to the muscles. Such disturbance of the body’s heat regulation would trigger the occurrence of heat stroke. The result could be fatal if multiple organ complications emerge.

Hence, the runner should be aware of such as high internal temperatures and significant changes in one's mental state. In addition, unusual chest pains or palpitations, disorientation or confusion could also indicate cardiac-related conditions and other injuries.

If runners could observe points mentioned above, they might minimize their risk of having fatal consequence during the marathon event.
