...Life-Style. What bothers Russek the most, however, is the dearth of medical treatment preceding a decision to operate. Russek reviewed the medical treatment that had been given to 200 patients admitted to hospitals for surgery to correct uncontrollable angina. Nearly half had been treated with nothing other than nitroglycerin, a drug used to dilate or expand the arteries. In most of these cases, the drug had been used only to help abort an attack of angina-not to modify the conditions that led to the pain. On the other hand there had been insufficient effort to deal with either...

But other workers still run some risk, even though the plant's nitroglycerin dust levels are far lower than those allowed by the Government. One hundred and sixty employees work with nitroglycerin at the plant. Though only .6% of such an adult group would normally show signs of coronary heart disease, Lange found 5% of the employees to be suffering from some kind of heart handicap...
