Physicians in the Third Reich were aware that smoking is responsible for cardiac diseases, which were considered to be the most serious diseases resulting from smoking. The use of nicotine was sometimes considered to be responsible for increased reports of myocardial infarction in the country. In the later years of World War II, researchers considered nicotine a factor behind the coronary heart failures suffered by a significant number of military personnel in the Eastern Front. A pathologist of the Heer examined thirty-two young soldiers who had died from myocardial infarction at the front, and documented in a 1944 report that all of them were "enthusiastic smokers". He cited the opinion of pathologist Franz Buchner that cigarettes are "a coronary poison of the first order."
