title: [Coronary risk profile in women with angiographically normal coronary arteries or initial coronary arteriosclerosis].
abstract: The pathophysiology and prognosis of coronary heart disease in women are the subject of intensive epidemiological and clinical investigations due to sex specific considerations. We have estimated the prevalence of modifiable coronary risk factors in 36 consecutive women (mean age 59.7 years) with suspected coronary heart disease in whom coronary angiography was performed due to unclear chest pain. Seventeen women revealed angiographically normal coronary arteries (gr. I) and 19 women showed coronary vessels with initial arteriosclerosis (luminal diameter reduction < 35%) (gr. II). Mean age was 59.1 years in gr. I and 60.3 years in gr. II (p = ns). No woman received lipid lowering drugs within the last 6 months. A hormone replacement therapy was not performed in any case. Women in gr. I showed significantly higher total and LDL cholesterol levels (271.6 +/- 34.3 vs 243.5 +/- 44.8 mg/dl; p < 0.005 and 190.5 +/- 36.8 vs 149.7 +/- 45.1 mg/dl; p < 0.025, respectively) and significantly lower HDL cholesterol values (57.8 +/- 16.5 vs 72.8 +/- 19.1 mg/dl; p < 0.0125) compared to women in gr. II. The total/HDL cholesterol ratio was 3.6 +/- 1.2 in gr. I and 5.1 +/- 1.7 in gr. II (p < 0.005). The positive predictive value for the existence of initial coronary atherosclerosis and a total cholesterol/HDL ratio > 4 was 76.5%. The negative predictive value and a ratio < 4 was 81.3%. Women in gr. I revealed 1.2 +/- 0.9 and in gr. II 1.6 +/- 0.8 risk factors (smoking, hypertension, body mass index > 30 kg/m2, diabetes mellitus, hyperlipidemia) (p < 0.10). The 10-year risk for the occurrence of a coronary event was 9.1 +/- 3.7% in gr. I and 14.2 +/- 5.8% in gr. II (p < 0.005). The positive predictive value for the existence of initial coronary atherosclerosis and a 10-year risk > 10% was 90%. The negative predictive value and a 10-year risk < 10% was 64.0%. Our investigation indicates that women with a mean age of 60 years, unclear chest pain and without exercise induced ischemia are highly suspected to have initial coronary arteriosclerosis, when a distinct risk factor profile and a 10-year cardiac event risk > 10% are present. For this high risk group of women, intensive secondary prevention measures are necessary.
