It has also been observed for many years that women have less coronary disease than men. As long ago as 1803, William Heberden recorded that there were only 3 women in nearly 100 patients with pectoris dolor (angina pectoris).1 In a series of 30,000 autopsies, Clawson found a malefemale ratio of 8:1 among patients with coronary sclerosis without hypertension.2 Clinical studies of coronary heart disease have also shown a sex difference, Levy and Boas3 reporting a male-female ratio of 4.9:1, and Master, Dack, and Jaffe4 reporting 3.4:1. These studies have confirmed the observation that women have a decreased incidence of coronary atherosclerosis as compared with men.Even more striking is the rarity of this disease in women under 40 SN - 0888-2479 M3 - doi: 10.1001/archinte.1959.00270120064010 UR - http://dx.doi.org/10.1001/archinte.1959.00270120064010 ER -
