The dog model of left ventricular remodeling after myocardial infarction.

abstract：BACKGROUND:Telemonitoring has been advocated as a way of decreasing costs and improving outcomes, but no study has looked at true Medicare payments and 30-day readmission rates in a randomized group of well treated patients. OBJECTIVE:The aim of this work was to analyze Medicare claims data to identify effects of home...
