Method for treating myocardial infarction
First Claim
Patent Images
1. A method for treating a patient with myocardial infarction, comprising:
- delivering pacing pulses to one or more sites in proximity to an infarcted area with a selected pacing mode, wherein the pacing pulses are delivered in a manner that pre-excites the site or sites in proximity to the infarcted area relative to other areas of the ventricle;
evaluating hemodynamic performance by measuring a variable selected from dP/dt, pulse pressure, and left ventricular systolic pressure; and
,optimizing one or more pacing parameters by selecting values which result in a minimum left ventricular end-diastolic pressure (LVEDP) without adversely affecting hemodynamic performance.

Abstract
A method for treating patients after a myocardial infarction which includes pacing therapy is disclosed. A cardiac rhythm management device is configured to deliver pre-excitation pacing to one or more sites in proximity to an infarcted region of the ventricular myocardium. Such pacing acts to minimize the remodeling process to which the heart is especially vulnerable immediately after a myocardial infarction.
