Does Baroreflex Sensitivity Add Something to Noninvasive Evaluation of Post-Infarction Patients?
In patients recovering from acute myocardial infarction considerable attention has been given for many years to noninvasive measurements of parameters that can identify high risk groups in which further investigation and intervention are needed. The extent of coronary artery disease and of myocardial damage as assessed by exercise stress test and determination of left ventricular ejection fraction together with the presence of electrical instability indentified by the results of 24-h Holter recording have been recognized as the most important pathophysiological determinants of prognosis after myocardial infarction. However, changes in life style and therapeutic interventions have modified the profile of patients with acute myocardial infarction, and the attending improvement in post-discharge survival has affected our ability to identify high risk patients by the use of traditional means.
