Method for treating cardiovascular disease using implantable electroacupuncture device

A method of treating heart failure, coronary artery disease, myocardial ischemia or angina in a patient using a leadless implantable electroacupuncture device (IEAD) that includes a central electrode of a first polarity and centrally located on an outside surface of a housing of the leadless IEAD and an annular electrode of a second polarity and that is spaced apart from and surrounds the central electrode on the outside surface of the housing of the leadless IEAD, said method comprising:

• (a) implanting the leadless IEAD below a skin surface of the patient at or near an acupoint selected from a group of acupoints that includes:
• PC6, ST36, BL14, EX-HN1, HT7, HT5, LI11, LU2 and LU7, and
• (b) enabling the leadless IEAD to apply stimulation sessions at the acupoint by way of the central electrode and the annular electrode in accordance with a stimulation regimen, wherein the stimulation sessions each comprise a plurality of stimulation pulses, wherein the stimulation regimen defines the stimulation sessions to each have a duration of T3 minutes and a rate of occurrence of once every T4 minutes, wherein a ratio of T3 to T4 is no greater than 0.05, and wherein T3 is at least 10 minutes and no greater than 60 minutes.
