In the last newsletter, we worked through the anatomy of the heart -- primarily to lay the groundwork for this issue. By using what we learned in the last issue, we can now explore: Things that can go wrong with the heart. Incidentally, if you haven't read the previous newsletter, Anatomy of the Heart, you might want to do that now. It's not absolutely necessary, but it will make for a more rewarding experience as you read this newsletter. Problems of the epicardium
Problems that can occur with the heart lining pretty much fall into two categories Physical damage. Physical damage is easy to understand, and usually easy to repair. You're driving in your car, you get into an accident. You're slammed against the steering wheel or an airbag. Your body stops suddenly but your heart, powered by inertia (an object in motion tends to stay in motion) keeps moving forward and tears the pericardium that holds it in place before bouncing back and coming to rest. This causes bleeding in the pericardial sac, which serves as the buffer between the heart and the chest wall and lungs. The extra fluid (blood) pumps into the sac under pressure which expands the sac, thereby squeezing and constricting the heart. If the pressure isn't relieved, it can build to the point where it constricts the heart so much that it prevents it from beating. Herbs and neutraceuticals are not much use here. Fortunately, medical intervention tends to be easy and effective in these situations. A catheter inserted into the sac to drain the excess blood and relieve the pressure will usually do the trick -- along with stopping the bleeding. Inflammation (known as "itis" in medical terminology) is a little more complex. The primary cause of inflammation of the heart lining is infection, both viral and bacterial. Depending on which part of the lining is affected, it will be called pericarditis, endocarditis, or epicarditis. The inflammation can cause chest pain, difficulty pumping, or fever. These symptoms can be mild, acute, or even chronic. Standard treatment includes the use of antibiotics and antivirals. These are "usually" effective unless the underlying infection is resistant to the arsenal of drugs at your doctor's disposal, which is a growing problem. Fortunately, there are natural alternatives including garlic, olive leaf extract, oil of oregano, grapefruit seed extract, etc. that can work even in the case of drug resistant infections. Problems with heart valves
Backflow, or regurgitation, is caused by misshapen or damaged valves or ruptures to the tendons that hold the valves in place. These things cause the valves to imperfectly seal with each heartbeat, thus allowing backflow into the atria. Stenosis, or hardening of the valves, caused by disease or aging prevents the valves from fully opening. This limits the flow of blood into the ventricles so that they cannot fill completely in the fraction of a second the valves are open. Since the ventricle chamber is now partially empty when it pumps, it generates less pressure with each beat, which ultimately reduces the amount of blood that flows through the body. There can be multiple causes for both problems.
The bottom line is that the pumping process becomes less efficient, and your heart has to pump harder and faster to compensate. Treatments can range from doing nothing, to using drugs to reduce infection and inflammation, to surgically replacing the damaged valves with artificial valves. Doing nothing you might ask? Absolutely! In most cases, that's what doctors do. Why? The heart has tremendous reserve capacity. Last issue we mentioned that you can have 70% blockage of your coronary arteries and never experience any outward symptoms. It doesn't stop there. Your heart also has a tremendous reserve pumping capacity and when called upon can increase output 5-8 times if needed. For example, in mitral valve prolapse (a condition in which the mitral valve "falls down", or prolapses too far into the left ventricle allowing for backflow into the right atrium), there are usually few symptoms or any problems. In most cases doctors will just make note of it and watch for any changes. On the other hand, sometimes, there are symptoms. These can include:
In those cases the valves are often replaced with mechanical valves. At one time, you could actually hear the mechanical valves make a slight clicking sound as they opened and closed 70-80 times a minute. This drove some people crazy when they tried to sleep at night. Newer models have overcome that problem and are silent. Now you might think since problems with valves are mechanical in nature that nutrition and supplements would not play much of a role in resolving them. If so, you would be wrong. Most medical doctors are not aware of this fact, but there are numerous studies showing nutrients matter -- and supplementation can actually change the mechanical aspects of valve function. For example, it has been shown that magnesium plays a role in mitral valve prolapse. Therapeutic effect of a magnesium salt in patients suffering from mitral valvular prolapse and latent tetany. Magnesium Deficiency in the Pathogenesis of Mitral Valve Prolapse.
Circulatory problems
Which part of the muscle is damaged. (Some parts are more critical than others.) How extensive the damage is. In some cases, people do indeed die from their first heart attack. In most cases, though, the attacks are progressive -- with each attack killing more and more tissue until the remaining heart muscle can no longer carry the load. Depending on the extent of the damage, standard medical treatments include: Drugs, such as: Heart transplants.
Far and away the biggest problem with all of these treatments, though, is that they only treat one manifestation of the problem, not the underlying cause -- the fact that the arteries are blocking in the first place. It is here that alternative therapies excel -- both short term, and long term. For example: Dietary changes can have a profound impact in reversing coronary heart disease as can a number of supplements. Shifting the balance of Omega-6 to Omega-3 fatty acids can eliminate a major source of heart attacks. Blood Clots
Preventing blood clots reduces the risk of stroke, heart attack and pulmonary embolism. The standard treatment for those at risk of embolisms involves the use of drugs such as Heparin or warfarin (a form of rat poison), which are anticoagulants used to inhibit the formation and growth of existing blood clots. But these drugs are dangerous and require constant watching and regulating since they can cause internal bleeding. Far safer (and better since they also dissolve arterial plaque and help promote the repair of arterial tissue) are proteolytic enzyme formulations that incorporate specialized enzymes such as nattokinase. Problems with the heart muscle -- the myocardium
Problems in the atria
Problems with the ventricles
Myocarditis, or inflammation of the heart, is a form of cardiomyopathy (which literally translates as "heart muscle disease"). The problem here is that blood flows more slowly through an enlarged heart, which increases the likelihood of blood clots. In addition, people with cardiomyopathy are often at risk of arrhythmia and/or sudden cardiac death. When cardiomyopathy results in a significantly enlarged heart, the mitral and tricuspid valves may not be able to close properly, resulting in murmurs. There may be multiple causes of myocarditis, including viral infection. Common culprits include: influenza, herpes, Epstein-Barr, hepatitis, and salmonella. Ischemic cardiomyopathy is a weakness in the muscle of the heart due to inadequate oxygen delivery to the myocardium, with coronary artery disease being the most common cause. (Ischemia simply means "reduced blood flow.") Anemia, sleep apnea, and hyperthyroidism can also contribute to ischemic myocardium. Myocardial infarction literally means the "death of heart muscle tissue." Since heart muscle does not grow back, this has a snowball effect. If you have a heart attack that starves part of the heart muscle of oxygen so that it dies, that scar tissue does not recover. You now have a weakened heart that is more likely to suffer a subsequent attack -- leading to more heart muscle damage and increased chances for a third attack. And so on. It's not too hard to see where this leads -- to long-term loss of heart muscle activity and chronic heart failure. Congestive heart failure (CHF) is a condition in which your weakened heart can no longer pump out all the blood that flows into it. CHF is the most common cause of hospitalization for people over age 65. It kills more than 50,000 people a year in the US and costs the health care system more than $50 billion per year. The heart is just like other muscles. When it is weakened, it becomes enlarged and inefficient. This leads to congestion and flaccid muscle tone. In fact, it can even lead to prolapse of the heart in which the heart literally "drops" from its original position in the chest. It is not unusual to require a stethoscope placement three to five inches below the normal area when listening to a weakened heart. Unfortunately, modern medicine comes up short when it comes to problems of the myocardium. Mostly it just deals with the aftermath. If the heart stops beating, use the electric paddles to get it going again. - All of the B vitamins, but especially vitamin B4 are essential for heart health.
Heart rhythm disorders
To quickly review from last issue.
Electrical impulses leave the SA node and travel through special conducting pathways in the heart to the atrioventricular node (AV, node). The purpose of the AV node is to provide a pathway for impulses from the atria to the ventricles. It also creates a delay in conduction from the atria to the ventricle. This delay allows the atria to contract first, allowing the ventricles to fill with blood before they contract themselves. The delay ensures proper timing so that the lower chambers have time to fill completely before they contract. From the AV node, the signal travels down through a group of fibers in the center of the heart called the bundle branch-- and then to the ventricles. So what can go wrong?
The AV node normally has one group of cells through which the electrical impulse can travel. However, due to aging or heart disease, it is possible for the AV node to develop two or more groups of conductive cells. Because of the extra conduction pathways, your heart can at times beat more quickly than normal. The bundle branch (see above) becomes "blocked" as a result of a heart attack which damages the inner heart muscle and nerves. This stops the signal from traveling from the AV node to the ventricles. Left to their own devices, the ventricles establish their own rhythm of about 20-40 beats per minute. This is much too slow for health and results in weakness, fainting, and shortness of breath. Valve stenosis (stiffness) causes increased pressure in the atria (since blood never fully clears) which causes ballooning of the walls of one or both of the atria (aka atrial dilation). Because the atrium is now bigger, it increases the distance signal has to travel. The increased distance means it takes longer for the signal to reach its final destination which throws off the pacing of the heartbeat. Medical Treatments
The other option, of course, is the pacemaker. The pacemaker uses electrodes attached to the heart that take over from the SA node to control the beating of the heart. The pacemaker is run by a small computer installed in the body. Modern pacemakers are externally programmable and allow for the selection of optimum pacing modes for individual patients. Some can even self-regulate and adapt to changing requirements such as stress or exertion. And some combine a pacemaker and defibrillator in a single device. Drugs and pacemakers work reasonably well at keeping the heart going, but still address the problem after the fact. Keep in mind that in most cases the rhythm of the heart was lost through degradation based on nutrition or disease. Installing a pacemaker does not address that problem; it merely bypasses it. On the other hand, it is possible to reverse many of those conditions nutritionally and thus reverse many of the associated problems. Alternatives
Supplementing with CoQ10 can significantly improve the energy level of each cell in the heart, thus improving its ability to respond to an electrical stimulus and pass the signal on to its neighbor in a timely manner. Shifting the balance of Omega-6 to Omega-3 fatty acids can eliminate a major source of potassium imbalance which can trigger heart attacks. Conclusion
- What tests does your doctor run?
For now, though, it's worth reviewing a key concept: Although many problems with the heart may seem to be biomechanical in nature and beyond the purview of nutrition and supplements, that's not necessarily true. As we've seen: - Magnesium supplementation can change the shape and condition of heart valves.
As usual, it's not just about pharmaceutical drugs and surgical procedures. Following the principles of the Baseline of Health Program can change your heart…and your prospects for long-term survival.
