Abstract
In general, the invention is directed to systems and techniques for assessing a risk of ventricular tachyarrhythmia in a patient by measuring one or more biochemical markers that reflect the health of a patient. Typically, the patient submits a sample, such as a blood sample, which is tested for one or more biomarkers. Based upon the results of the tests, the patient's risk of ventricular tachyarrhythmia may be assessed. When the patient is found to be at risk, the patient may receive an implantable medical device or drug therapy to address the risk.
Claims24
A method for assessing a risk of ventricular tachyarrhythmia in a patient using a plurality of biochemical markers, comprising the steps of:
- assessing the risk of ventricular tachyarrhythmia in the patient as a function of a measurement of a first biochemical marker A in the patient;
- assessing the risk of ventricular tachyarrhythmia as a function of a measurement of a second biochemical marker B in the patient;
- comparing a measure MA of the first biochemical marker A to a threshold value TA of A, wherein if MA is greater than or equal to TA, a risk of ventricular tachyarrhythmia does not exist in a patient, and wherein if MA is less than TA, a risk of ventricular tachyarrhythmia may or may not exist in said patient, and wherein if MA is less than TA, comparing a measure MB of the second biochemical marker B to a threshold value TB of B, wherein if MB is less than TB a risk of ventricular tachyarrhythmia does not exist in the patient, and wherein if MB is greater than or equal to TB, a risk of ventricular tachyarrhythmia may or may not exist in the patient.
