CRT-D can be a good answer to perilous heart diseases
This news may be breathtaking for many people, in particular suffering heart diseases. It has come to the knowledge that the steady application of an advanced type of heart defibrillator made by companies with strong roots in Minnesota can be beneficial. This development has been corroborated by a recently conducted study.
The study was carried out among 1,820 patients, if not more, under the auspices of medical technology standards and it was found that patients treated with a distinctive device called cardiac resynchronization therapy defibrillators (CRT-D) were 41 percent less probable to be hospitalized or need outpatient therapy.
However there is a new perspective as well. Even though it is true that the pricey CRT-D device spared many patients from going to the hospital, it did hardly make any difference in saving lives, and some doctors consider they won't rush to implant more patients with them.
The study was funded by Boston Scientific Corp., known for employing about 2,500 people at its Cardiac Rhythm Management division in Arden Hills, but it will also benefit Fridley-based Medtronic Inc. and St. Jude Medical Inc., of Little Canada, which make versions of the device. The main intention of the study was to make a comparison in detail among patients who were treated with an implantable cardioverter defibrillator (ICD) to correct abnormal heart rhythms and patients who did receive cardiac resynchronization device, which helps the lower chambers of the heart pump all at once. It did the same with success.
"This will likely broaden the number of patients who will be treated with [CRT-D] devices," said Dr. William Katsiyiannis, a cardiologist at Minneapolis Heart Institute. "Now, only the sickest patients get these devices."
"Medtronic welcomes the added evidence of CRT effectiveness in this mildly symptomatic heart-failure patient population," said Dr. David Steinhaus, medical director of Medtronic's Cardiac Rhythm Disease Management business. It is to be noted that CRT devices sell for about $30,000, about $7,000 more than a traditional heart defibrillator.
