Implantable devices have been used for decades to treat heart disease. The first pacemaker was implanted over 40 years ago, and implantable defibrillators were first used in the early 1980s. But the last few years have witnessed a surge in both the types of devices being tested for heart-failure treatment, and in the optimism of experts about their usefulness.
There’s no cure for congestive heart failure -- not yet anyway. But if you or a loved one is among the 5.8 million Americans living with heart failure, even if it’s advanced, you should know that simple self-care measures can effectively help curb fatigue, shortness of breath, swelling, and other symptoms.
In addition to improving their quality of life, heart failure patients who practice good self-care are less likely to wind up in the hospital.
“Heart failure is a progressive disease, but the...
"A lot of the big advances that we've had in treating heart failure in the last few years has been with devices," says Marvin A. Konstam, MD, chief of cardiology and director of cardiovascular development at Tufts-New England Medical Center. "It's an exciting time."
Eric Rose, MD, agrees. "Things are dramatically different in the last five years," says Rose, department of surgery chairman at the Columbia University College of Physicians and Surgeons. "For instance, the dream of using machines for long-term supportive patients with end-stage heart failure is now a reality."
But Rose, who led a study of one such implant used in heart-failure treatment -- the left ventricular assist device -- is temperate in his enthusiasm. "It's a reality, but I should say that it's a reality with mediocre outcomes at this point," he tells WebMD. "That's still an improvement over God-awful, which is what the prognosis was before."
While advances in devices are impressive, all experts agree that we are only in the early stages of their development. It remains to be seen how widely and how quickly these life-saving implants will become available for routine heart-failure treatment.
Given that heart failure is not a specific disease in itself, but rather a condition that results from other illnesses, different approaches have been developed to treat the condition. Some stem from the familiar pacemaker, others from devices designed as a stopgap before heart transplant.
Implantable Cardioverter Defibrillators (ICDs)
An ICD is used for heart-failure treatment when the person is considered to be a high risk of dying from an abnormal heart rhythm -- called sudden cardiac death. It is a small device that is implanted in the chest and continually monitors the heart's rhythm. If the ICD senses a dangerous abnormal heart rhythm, it delivers an internal electric shock to the heart -- the equivalent of being shocked with paddles outside the body -- that hopefully restores a normal heart rhythm.
