An amazing discovery has just taken place as it appears that stroke risks can be reduced with stents. This might prove to be a life-savior for many, since cardiovascular diseases are the top causes of deaths across the United States.
Numerous people are prone to cardiovascular diseases that can lead to strokes. This type of condition is ranked as the top killer in the U.S., even though cancer has taken the top spot in 22 states. Up until this moment it was believed that surgery was the most drastic and effective method of reducing this risk. However, a new study has reached a different conclusion.
The two studies were conducted by researchers from the Mayo Clinic, the Rutgers University and the University of Alabama at Birmingham. 117 medical centers across the U.S. and Canada were involved in the research.
The first part of the study took place over five years during which scientists analyzed both surgery and stents. ACT 1 or the Asymptomatic Carotid Trial confirmed that both procedures are safe for patients suffering from cardiovascular diseases. The second stage involved determining which procedure was more effective, since both were equally safe. CREST or the Carotid Revascularization Endarterectomy versus Stenting Trial lasted for five years as well. During this part, 2,502 people who have had arterial clogging surgery or stents were analyzed.
The study followed the condition of the patients for the following ten years by receiving updates every six months. Its results were released in the New England Journal of Medicine.
The conclusion of the extensive and long lasting research was that both surgery and stents are equally safe for cardiovascular patients and equally effective in reducing the risk of heart attacks and strokes. It appears that the most important part is unclogging the arteries no matter which procedure the patient follows, and this operation is sure to prevent both mortal events. A report proves that the risk for stroke has dropped to 6.9% to those who administered stents and to 5.6% for those who went through surgery. As for the chances of heart attacks, these have reached values of 9.9% for patients with surgery and 11.8% for those with stents.
In the end, it has become clear that stroke risks can be reduced with stents, which are almost as effective as surgery. We are finally presented with two options for avoiding the diseases that cause the most deaths worldwide.
