EECP therapy is a non-invasive and clinically proven method used for patients with angina or Congestive Heart Failure (CHF). This is the most commonly used method of treating heart disease in patients with angina pectoris. It causes chest pain due to the supply of blood to the heart, increased demand for oxygen by the heart, or a combination of both. Angina is a symptom that indicates coronary artery disease. And most likely it points to the possibility of heart attacks.
