Hypertension Risks from the Iron Brake Particulate Matters

 Of 12 moonwalkers, James Irwin on the day after return from Apollo 15 mission, showed extraordinary bicycle (B) stress          test (ST) hypertension (275/125) after 3 minutes exercise; supervising > 5000 maximum treadmill  ST,  author  never  witnessed ST- blood pressure approaching this level. Symptom-limited maximum B stress test showed “cyanotic fingernails, possibly venous blood trapped peripherally, supporting author’s “Apollo  15  Space  Syndrome,”  postulating  that  severe  fingertip pain during space walks, triggered by plasma fluid, trapped distally; mechanism could be related to endothelial dysfunction, providing “silent ischemia” warning. Neil Armstrong returned to Earth with severe  diastolic  hypertension  (160/135), consistent with ischemic left ventricular dysfunction; 50 mm increase in comparison with resting BP 110/85. With inhalation of lunar dust, brought into habitat on space suit, with high lunar iron (I) this dust inhalation, along with reduced (R) space flight- transferrin, R antioxidant, calcium (Ca) blocker-magnesium, conducive to severe oxidative stress, Ca overload     with potential endothelial injuries. Using moonwalker studies as example, my recent editorials show that I dust, released from brakes, with over 90% of brakes made of I, is a major hypertension factor and may also contribute to myocardial infarctions.
