Key Words: Editorials • heart diseases • sex • women

Despite the popular concept that heart disease preferentially affects the male population, in every year for the past 16 years, cardiovascular disease has killed more women than men.¹ Unfortunately, a disparity still exists between men and women in the diagnosis and aggressive treatment of heart disease. The perception that women are relatively protected is reflected by the fact that women are much more fearful of dying from some form of cancer than from cardiovascular disease.¹ Understanding any risk factors that predispose or protect the female population from cardiovascular and coronary disease is therefore a compelling goal for the research community.

Left ventricular hypertrophy is a compensatory response of the heart to a variety of stresses, and it is a strong predictor of morbidity and mortality in individuals whether or not they have been diagnosed with cardiovascular disease. Sex differences in the development of this disease over time have been suggested by clinical studies dealing with patients who suffer from aortic stenosis or hypertension.^2,3 For example, older female patients with aortic stenosis tend to have increased hypertrophy accompanied by greater concentric remodeling and preserved left ventricular function when compared with male patients. Premenopausal women, in fact, exhibit a thinner posterior wall, smaller left ventricular mass, and better load-dependent and load-independent cardiac function than age-matched men under conditions of mild essential hypertension.⁴ Population studies have shown an age-dependent increase in left ventricular mass in healthy normotensive women that is not seen in men, as determined by echocardiography.⁵ These and . . .
