BACKGROUND: Observational and experimental data underscore the cardioprotective effects of hormone replacement therapy (HRT). On the other hand, the randomised trial available, the 'Heart and Estrogen/Progestin Replacement Study (HERS)', showed no reduced risk of coronary heart disease (CHD), using HRT. AIM: Opinion survey on the effect of HRT on CHD risk. SETTING: Identification of articles on the related topic using a Medline search. Written survey of the authors' opinion towards HRT in relation to CHD. RESULTS: Thirty-seven of the 108 principal authors responded. Among them, respectively, 16 (43%) and seven (19%) found that HRT has favourable effects on primary and secondary prevention, two (5%) and five (14%) that it had no effect, none (0%) and four ( 11%) that it had an unfavourable effect, seven (19%) and nine (25%) that it had both favourable and unfavourable effects, and nine (25%) and ten (27%), thought that there are not enough data. Considering a risk modification superior to 20% as clinically relevant, then 57% thought that HRT has a beneficial effect of on primary prevention and 30% on secondary prevention, while none of the responders considered that HRT has unfavourable effects on primary prevention and only 2% on secondary prevention of CHD. CONCLUSION: Despite the negative results of the HERS study, about one-half of the responders still think that HRT has a beneficial effect on primary prevention of CHD and almost one-third on secondary prevention.
