CorrespondenceCoronary artery disease and lunar catecholamine cardiomyopathy

ObjectiveShow how lunar catecholamine cardiomyopathy alone, exemplified by Neil Armstrong's single space walk, prior to exposure to inhalation of fine particulate matter, can trigger “ Neil Armstrong Syndrome” or by Irwin with coronary, possibly hypertensive heart disease, and catecholamine cardiomyopathy. With space flight, invariably magnesium ion deficits, catecholamine elevations, vicious cycles. Design Use lunar heart rates while configuring rover to show severe tachycardia component of the syndrome. Use Irwin's stress test-“ cyanotic fingernails” to support Apollo 15 Space Syndrome. Use Irwin's autobiography to compensate for often incomplete data. Results Paper shows that both Irwin as well as Armstrong meet criteria of my 2nd. Space Syndrome: severe thirst, severe shortness of breath, severe tachycardia, the latter, corrected by replenishing plasma volume. Conclusions Irwin, with a history of hypertension prior to the Apollo 15 mission and classical angina during Earth reentry, may have had coronary as well as hypertensive heart disease whereas there was no evidence that Armstrong had these conditions prior or during his mission. However both, on return to Earth, had abnormal stress tests.
