Age- and gender-specific awareness, treatment, and control of cardiovascular risk factors and subclinical vascular lesions in a founder population: the SardiNIA Study

AIM

We investigated the gender-specific control of cardiovascular (CV) risk factors and subclinical vascular lesions in a founder population in Italy.

METHODS AND RESULTS

6148 subjects were enrolled (aged 14-102 years) from four towns. Hypertension (HT), diabetes mellitus (DM) and dyslipidemia (LIP) were defined in accordance with guidelines. A self-reported diagnosis defined awareness of these conditions, and the current use of specific medications as treatment. Prevalence was HT 29.2%, DM 4.8%, LIP 44.1% and was higher in men than in women. Disease prevalence increased with age for every CV risk factor. Men were less likely than women to take anti-HT drugs and to reach BP control (9.9% vs. 16%). Only 17.6% of HT > 65 years had a BP < or =140/90 mmHg, though 48.5% were treated. The use of statins was very low (<1/3 of eligible subjects > 65 years, those with the highest treatment rate). The ratio of control-to-treated HT was lower in subjects with, than in those without, thicker carotid arteries (31.5% vs. 38.8%, p < 0.05) or stiffer aortas (26.0% vs. 40.0%, p < 0.05) or carotid plaques (26.3% vs. 41.1%, p<0.05).

CONCLUSION

A large number of subjects at high CV risk are not treated and the management of subclinical vascular lesions is far from optimal.

Influence of vaginal danazol on uterine and brain perfusion during hormonal replacement therapy

OBJECTIVE

To evaluate the effectiveness of vaginal danazol as progestin supplement to estrogen replacement therapy, and its interference with uterine and carotid artery flow compared with medroxyprogesterone-acetate (MPA), estrogen alone, and placebo.

METHODS

Forty healthy women at least 12 months after natural menopause were randomly divided into four treatment groups: Group 1 (n=10), continuous transdermal estradiol (TE) (50 microg/day), plus a monthly 10-day course of MPA (10 mg/day); Group 2 (n=10), continuous TE plus a monthly 10-day course of vaginal danazol (200 mg/day); Group 3 (n=10), TE alone; Group 4 (n=10), placebo. At baseline and during the first, third, and sixth month of treatment, the endometrial thickness was assessed by transvaginal ultrasonography, while the pulsatility index (PI) of the carotid and uterine arteries was assessed by color Doppler. An endometrial biopsy was also performed before and after the treatment.

RESULTS

At baseline, no significant differences between ages and other evaluated parameters were present in the four groups. In groups 1, 2, and 3, the values of carotid and uterine PI decreased significantly and similarly during the treatment, while in group 4 they were unchanged. In group 3 only, the endometrium was significantly thicker during treatment than before. No endometrial hyperplasia was present in the four groups at the end of the treatment.

CONCLUSIONS

Vaginal danazol seems to be capable of counteracting the mitogenic effect of estrogen on the endometrium without reducing the effectiveness of estrogens to improve peripheral arterial perfusion.
