Frequently asked questions
What is Renew™ ECP Therapy?
Renew™ ECP Therapy is a non-invasive and non-surgical therapy process that uses a medical device to deliver External Counterpulsation (ECP). ECP enhances blood flow through timed inflation of pressure cuffs wrapped around the calves, thighs and hips. The inflation of pressure cuffs occurs in between each heartbeat, compressing the blood vessels and pumping blood back to the heart and throughout the body. This enhanced blood flow brings about a multitude of health benefits.
How does ECP work?
Three sets of inflatable cuffs, much like ordinary blood pressure cuffs, are wrapped around the calves, thighs and hips. ECG electrodes applied to the chest enable the Renew™ NCP-5 system to time cuffs inflation precisely to the rhythm of your heartbeat. When the heart is at rest, the cuffs are inflated sequentially from the calves to the hips. This compresses the blood vessels, thus enhancing circulation of blood flow back to the heart. Prior to the next heartbeat, all three cuffs deflate simultaneously. The rapid deflation of the cuffs significantly reduces the amount of work required of the heart to pump oxygenated blood to the rest of the body.
Is there a difference between ECP and enhanced ECP treatment?
The earliest ECP devices inflated all the cuffs simultaneously. To better “milk” blood from the legs, more recent devices inflate the cuffs in a sequential manner: first the calves, then the thighs, then the hips. This improved version of ECP is often called “enhanced ECP”. Since all modern ECP machines use some variant of the “enhanced” method, the terms ECP and enhanced ECP are sometimes used interchangeably. Renew™ NCP-5 uses the enhanced ECP technology.
What are the benefits of receiving Renew™ ECP Therapy?
ECP therapy enhances blood flow to all parts of the body, including organs such as the brain, heart, kidneys, liver and skin. This improves delivery of oxygen and nutrients and removal of carbon dioxide and waste product. The hemodynamic effects from ECP therapy leads to improved endothelial functions and stimulates release of nitric oxide. Clinical evidences indicated that ECP promotes vascular health (fitness of the arteries) and reduces inflammation1.
Renew™ ECP Therapy is indicated for treatment of chronic stable angina. Renew™ NCP-5 is cleared by the U.S. FDA and approved by the Singapore HSA. Many clinical studies have proven ECP to be effective in reducing angina symptoms and improving exercise capacity in patients with angina pectoris2.
Besides chronic stable angina, many clinical studies on ECP have also been done and have shown beneficial effects for the following conditions:
- congestive heart failure3, 4
- diabetes5, 6
- high blood pressure7, 8, 9
- ischemic stroke10, 11
- renal diseases12, 13
- erectile dysfunction14, 15
Please refer to the references for some of these clinical studies. As with most medical-related procedures, results may vary from patient to patient.
Who is Renew™ ECP Therapy suitable for?
Renew™ NCP-5 ECP device is indicated for the treatment of chronic stable angina. However, with enhanced blood circulation, ECP therapy also improves many other symptoms associated with poor blood circulation, such as, fatigue, weakness, shortness of breath, dizziness, numbness, and swelling.
Many clinical studies have shown ECP to have beneficial effects for the following conditions:
- congestive heart failure3, 4
- diabetes5, 6
- high blood pressure7, 8, 9
- ischemic stroke10, 11
- renal diseases12, 13
- erectile dysfunction14, 15
Please refer to the references for some of these clinical studies.
Prior to starting Renew™ ECP Therapy sessions, patients are recommended to undergo an ECG test. If your patients have any of the conditions listed in the Contraindications, they should not undergo Renew™ ECP Therapy.
