~Cardiovascular Disease - Simplified Analysis
Reprinted with permission of Life Extension®.
Cardiovascular disease is rarely caused by a single frailty. Rather, it is a multifaceted failure that includes physical, psychological, and genetic weaknesses. Since cardiovascular disease remains the number one killer in Western societies, there is more published scientific information about its prevention and treatment than exists for other diseases. Overlooking just one risk factor, such as elevated levels of C-reactive protein, fibrinogen, or homocysteine, could lead to the development or worsening of the heart and/or vascular disease.
At least 68 million people in the United States suffer from some form of heart disease, with an estimated 1.1 million Americans annually experiencing an acute myocardial infarction (MI or heart attack). According to current statistics released from the American Heart Association, cardiovascular disease accounts for about 950,000 deaths annually (about 41% of total mortality from all causes); coronary heart disease accounts for 460,000 of those deaths. In fact, one person dies every 33 seconds from heart disease, culminating in about 2600 deaths every single day. Additionally, the scope of this insidious health problem is worldwide. Globally, cardiovascular disease accounts for almost 50% of all deaths (GSDL 2002).
NEW: EVIDENCE THAT CARDIAC CELLS DIVIDE AFTER A HEART ATTACK
Most tissues and organs are equipped to deal with injury more efficiently than the heart. For example, the mending of broken bones and renewal of injured skin is so mundane they are taken for granted. Until recently, it was thought that myocytes (muscle cells) of the adult heart were incapable of self-renewal; once damaged, always damaged, without hope of regeneration. Reports published in the New England Journal of Medicine indicate this may not be the case (Beltrami et al. 2001).
Researchers looked at heart muscle cells from the hearts of 13 deceased patients, 4-12 days after their heart attack. These findings were compared to the hearts of 10 patients who had not died of cardiovascular disease. Samples of heart tissue were taken from the area near the site of the heart attack and from a site more distant from the damage. Scientists found that the number of myocytes multiplying in diseased hearts was 70 times higher in the border zone and 24 times higher in the remote area. The presence of cell division in the nondiseased portion of the heart suggests a continuous turnover of cells during the lifespan of the organism. It is now thought that cardiac muscle cells can reproduce, advancing the premise that this process may be a component of the growth reserve of the human heart. The ramifications of this research allow for the prospect of replacing damaged myocardium by stimulating the heart's own repair capacity.
The focus of current study is to identify the premature stem cells that give rise to multiplying myocytes, encouraging growth and repair in damaged areas. The challenge will be to persuade these cells to move to regions of tissue damage to facilitate repair and reduce heart failure. While these reports raise hopes for employing the body's capacity for self-renewal, the excitement must be tempered by the scope of the obstacles. While the hurdles to overcome are sizable, current studies have advanced understanding by challenging dogma. Demonstrating that cardiac muscles are capable of regeneration opens up remarkable pathways for healing an ailing heart (Mercola 2001a).
A Simplified Daily Program for Cardiac Health
You can take each of the nutrients listed below separately if you choose to. This will involve spending a lot of time and money. Most people find it more convenient to take specially designed formulas that provide most of the recommended cardiovascular-protecting nutrients. Here is a brief description of six formulas that provide optimal potencies of most of the nutrients described:
Life Extension Mix
This formula contains 89 different ingredients including the following nutrients that have been shown to benefit cardiovascular health:
Vitamin E (alpha tocopherol)

Taurine is hypotensive; arouses the parasympathetic nervous system; is beneficial in congestive heart failure and arrhythmias; and has blood thinning and diuretic properties; suggested dosage, 1500-4000 mg in divided dosages daily.
Testosterone modulates cholesterol; dilates blood vessels; improves circulation; lessens angina attacks; and reduces blood pressure. The objective is to restore testosterone level to that of a healthy 21-year-old.
+ Thiamine (vitamin B1) reduces cardiac arrhythmias, palpitations, congestive heart failure, and elevated venous pressure. Some patients may realize benefit from 200-250 mg of thiamine a day; refractory cardiac arrhythmias may require 500-1000 mg a day.
+ Tocotrienols inhibit platelet-clumping; reduce cholesterol; and have antioxidant activity. A suggested daily dosage is 100 IU mixed tocopherols and 100 IU tocotrienols if the person is healthy, young, and without a family history of heart disease, and 200 IU of mixed tocopherols and 200 IU of tocotrienols for young adults with some cardiac risk factors or healthy people (50 years of age) without risk factors. 400 IU of mixed tocopherols and 400 IU of tocotrienols for people who have a personal or family history of cardiac disease. This dosage is appropriate for senior subjects and severely stressed or poorly nourished individuals.
