Learning goals What is refractory angina? -> Definition
Mechanism of angina pectoris LIMBIC SYSTEM AUTONOMIC NERVOUS SYSTEM ? MECHANICAL AND CHEMICUAL STIMULI DeJongste et al, Heart 2004
Refractory angina: scope of the problem INCOMPLETE REVASCULARIZATION RECURRENT ANGINA REFRACTORY ANGINA MICROVASCULAR DYSFUNCTION Abbate et al, Eur Heart J 2007
Recurrent angina: a true challenge Abbate et al, Eur Heart J 2007
Microvascular dysfunction Lanza, Heart 2007
Refractory angina: definitions Occurrence of chest pain due to myocardial ischemia in a patient with severe coronary artery disease who cannot be managed adequately by lifestyle adjustment or medical therapy and who are not candidates for revascularization (interventional or surgical) 1 ACC/AHA 2002 Guidelines 2 DeJongste et al, Heart 2004
Refractory angina: definitions A chronic (>3 months) condition characterized by the presence of angina caused by coronary insufficiency in the presence of CAD which cannot be controlled by a combination of medical therapy, PTCA and CABG. The presence of reversible myocardial ischemia should be clinically established to be the cause of the symptoms. 3 Mannheimer et al, Eur Heart J 2002
Learning goals Does refractory angina really exist? -> Epidemiology
US burden of refractory angina Yang et al, MCP 2004
US burden of refractory angina Yang et al, MCP 2004
EU burden of refractory angina Approximately 7% of people between 45 and 74 years suffer from angina pectoris. At least 14% of those in whom coronary revascularization is indicated are ineligible for it. Of all those with angina, 5-10% will develop refractory angina. This amounts to 30-50,000 persons/year. Lenzen et al, EJCN 2006; Mannheimer et al, Eur Heart J 2002
Angina despite optimal therapy Boden et al, NEJM 2007
Angina despite optimal therapy †p<0.05 at 1 and 3 years, but not at 5 years; ¶P<0.001 favoring PCI at all time points Boden et al, NEJM 2007
Reasons for not performing PTCA/CABG DeJongste et al, Heart 2004
Typical patient features DeJongste et al, Heart 2004
Learning goals Can I do anything about it? -> Management
How about angiogenesis? Why don’t we ask him what he wants? I’ve got this great new operation- I think it’ll help you Thanks Doc (?) The doctor-centered approach VS The patient-centered approach
The patient-centered approach • Level 1 • Tell patients about procedure related morbidity and mortality and proceed • Level 2 • Inform patients of risks and benefits in dialogue and help them come to a decision • Level 3 • Don’t take symptoms for granted. What really is the problem?
The approach to the patient with refractory angina Pain history; is the chest pain angina? Assess red flags (unstable angina, prognostically important disease) Optimise anti-anginal therapy Assess and address angina beliefs and fears Assess expectations in dialogue
The NORTHERN Trial of VEGF in refractory angina Stewart et al, TCT 2007
Still a role for PTCA/CABG: the MASS II Trial Hueb et al, Circ 2007
One-hour new patient appointment covering medical history, examination, education & distribution of patient information sheets Individual psychology covering relaxation techniques, and cardiac health anxieties. Usually 4 – 6 sessions TENS machine training from specialist nurses Follow up pain medical appointment to assess outcome of the first 2 treatment modalities. Assessment for stellate ganglion blockade Stellate ganglion block Medical review Cardiology review to exclude new disease Paravertebral block Medical review Implantable therapies: Spinal cord stimulation Intrathecal delivery systems Full angina pain management programme Management of refractory angina: the Greater Manchester Experience Opioid analgesics TENS=Transcutaneous Electrical Nerve Stimulator

Promising role of spinal cord stimulation
We must be ready to look for and listen to patients with refractory angina
A comprehensive and individualized approach is likely more successful
