Relax Your Heart

Achieving and Maintaining a Healthy Heart with Oxygen

More than 1.4 million Canadians are living with heart disease.  It is the second leading cause of death in the country.  To make matters worse, nine in ten Canadians have at least one risk factor for heart disease or stroke, such as high blood pressure or diabetes.

The numbers seem bleak, but the truth is 80% of premature heart disease and stroke can be prevented by adopting healthy behaviours.  Recent research studies on preconditioning have thrust hyperbaric oxygen therapy to the forefront of preventive intervention for the heart.

Preconditioning with hyperbaric oxygen therapy induces cardioprotection and decreases the likelihood of significant morbidity and mortality from a heart attack by limiting the size of dead tissue (also known as infarct).

Hyperbaric oxygen preconditioning involves “exposure to hyperbaric oxygen before a crucial event, with the plan to create a preventing therapeutic situation”.  Preoxygenation before recreational or work-related dives has long been known to reduce decompression times as well as post-dive nitrogen bubble loads.  Over the last decade, numerous clinical studies have shown the benefits of hyperbaric oxygen preconditioning prior to exposure to a clinical event.  Most notable protective effects from oxygen exposure are related to the heart and the brain.

Heart preconditioning with hyperbaric oxygen therapy induces cardioprotection and decreases the likelihood of significant morbidity and mortality from a heart attack by limiting the size of dead tissue (also known as infarct).  Moreover, it limits injury from oxidative stress during reperfusion by stimulating the body’s natural antioxidant defense system.  Both mechanisms contribute to the preservation of cardiac function after a heart attack.  When used in combination with stem cell therapy, hyperbaric oxygen therapy enhances stem cell uptake in the infarct area and enhances functional recovery of the heart.  For those undergoing bypass surgery, preconditioning with hyperbaric oxygen therapy induces endogenous protective mechanisms on the brain and the heart, improves myocardial function after surgery, shortens length of ICU stay, limits postoperative complications, and reduces cognitive dysfunction.

Hyperbaric oxygen therapy reduces the risk of dying from acute coronary syndrome by nearly 50%.

The benefits of hyperbaric oxygen therapy also extend to people suffering from acute coronary syndrome (unstable angina/chest pain or acute myocardial infarction/heart attack). Studies show that hyperbaric oxygen therapy reduces the risk of dying from acute coronary syndrome by nearly 50%.  If administered after thrombolytic therapy during a heart attack, hyperbaric oxygen therapy leads to faster chest pain resolution and favorably affects the heart’s remodeling process, manifesting as improved ejection fraction.  When used after angioplasty, hyperbaric oxygen therapy inhibits restenosis, thereby reducing the need for a repeat angioplasty or bypass surgery and lowering the incidence of a subsequent heart attack and death.

Prior to heart surgery, preconditioning with hyperbaric oxygen therapy induces endogenous protective mechanisms on the brain and the heart, improves myocardial function after surgery, shortens length of ICU stay, limits postoperative complications, and reduces cognitive dysfunction.

Diastolic dysfunction (an abnormality in the relaxation of the heart resulting in incomplete filling) is common among diabetics and ultimately leads to heart failure.  Repetitive application of hyperbaric oxygen therapy improves the relaxation capability of the heart among those with diabetes. 

An ounce of prevention is worth more than a pound of cure.  Hyperbaric oxygen therapy, with its many health benefits, can be a valuable resource towards achieving a healthy heart.  Take charge of your health and book your hyperbaric appointment today!
