Part “b”: the event horizon: (once this line is passed purchase rizatriptan 10mg with amex back pain treatment urdu, there is no going back): Cheney’s view is that the “event horizon” with respect to the heart is this: when the microcirculation defect within the heart itself begins to impact Q itself purchase 10 mg rizatriptan with mastercard pain treatment non-pharmacological, a vicious circle begins – microcirculation impairment reduces the Q, which produces more microcirculation impairment, which produces even more Q problems, so down goes the patient into the next phase of cardiac failure, which is the lung. Combined with liver impairment, this stage is known as hepatorenal failure, which is the requisite cause of death due to Compensated Idiopathic Cardiomyopathy. Cheney said “How will a patient know if s/he eventually loses the ability to compensate? Cheney emphasises that it is bad enough when patients do not perfuse their muscles and joints (because of poor microcirculation) but it is even worse when red blood cells are so deformed that they can barely get through the capillaries or are blocked entirely. He has found increasing the intake of potassium to be helpful (potassium induces aldosterone, a hormone that significantly increases blood volume), and that magnesium is beneficial as it is a vasodilator and helps reduce the resistance the blood encounters. He was a founding director of the International Association of Chronic Fatigue Syndrome, an association of scientists and clinicians). While free radicals may generate tissue injury, it is also evident that other oxidative by‐products, especially isoprostanes, can exert potent biological activity and act as a powerful vasoconstrictor of the peripheral vasculature. Isoprostanes have potent biological effects associated with increased cell permeability. They have also been shown to be powerfully vasoconstricting and are involved in endothelial injury. There are two types of heart failure: systolic (which is a failure to eject) and diastolic (which is not a failure to eject, but a failure to fill properly). Diastolic heart failure was first described in the 1980s but there was no significant literature until the 1990s, and no significant way to measure it until 2001. Cheney says that on physical examination: In phase 1: (immune activation) one sees • lymphyodynia (seen in 80‐90%) • crimson crescents bilaterally on soft palate (seen in 80%) • sub‐normal temperature In phase 2: one sees • evidence of subcortical brain injury • vestibular dysfunction (seen in 94%) • hyper‐reflexia, especially of the knees and ankles (seen in 70%) 134 In phases 3 and 4: the most interesting are the metabolic disturbances: • there is shortened breath‐holding capacity (seen in 60%) • there is very poor oxygen transport (seen in 90%): pulse oximetry readings measuring saturation of haemoglobin show a significant inhibition to desaturate • there is finger‐print destruction (seen in 50%): cross‐hatching occurs, with degradation of the ridges; punch biopsies found perivascular lymphoid infiltrates ie. Cheney says there are problems at cell level in energy production, and because of this degraded energy problem, patients suffer a defect in the ability to detoxify toxins, especially in the portal circulation (giving rise to gut toxicity as seen in phase 2). Gene alterations (seen in phase 4) generate a massive disturbance in the development of energy at the cell level. If you lose energy, you lose glutathione, but the more glutathione you give, the more you just create oxidised glutathione, which generates loss of citrate, causing a left shift on oxyhaemoglobin desaturation. Citrate also binds to magnesium, so over time the patient will develop a severe magnesium depletion syndrome. Cheney says that at least half of patients exhibited atrial cavitation, and that when these patients stood up, in 80% the filling volume collapsed. He tested this with magnesium and the results were significant: magnesium restored 12% of energy in one minute. Magnesium affects the intracellular energetics, proving that patients have a “tremendous” energy problem that is very sensitive to magnesium. The reason why patients are squeezing so hard is because they do not have enough energy to fill the chambers of the heart properly so they are trying to compensate by squeezing a lot harder (ie. If out of synchrony, the ventricle cannot cope, so cardiac output is severely degraded. A second consequence is that patients develop a strain pattern, which is an indication of ischaemia. Cheney has seen ischaemic changes in the inner ventricular wall because of the increased squeezing. There is a difference between diastolic dysfunction and diastolic failure: in diastolic dysfunction there is a filling problem but the body is compensating for it and achieving enough cardiac output to match metabolic demand. Diastolic failure begins when the body can no longer compensate and there is a reduction in cardiac output. According to Cheney, it is difficult to talk about a low cardiac output without talking about the involvement of the brain and the adrenal glands. If the cardiac output goes down, in order not to die, there is a rise in noradrenergic tone (also involving the adrenal glands) to bring the output back up. A mismatch between metabolic demand and cardiac output, even very briefly, will kill. In addition, an exercise test/re‐test of cardiopulmonary function is necessary because it is 100% objective and 137 confirms reduced functional capacity as well as post‐exertional malaise for disability purposes. These changes in serial testing point to a significant and confirmable physical abnormality, verifying the cardinal symptom of post‐exertional malaise. This work looked at inflammatory factors (free radical by‐ products and C‐reactive protein, an inflammatory marker) and found abnormally high levels of free radical by‐products and C‐reactive protein in patients but not in controls.
