Cost-effectiveness of low-dose colchicine in patients with chronic coronary disease in The Netherlands.

Aims: Recent trials have shown that low-dose colchicine (0.5 mg once daily) reduces major cardiovascular events in patients with acute and chronic coronary syndromes. We aimed to estimate the cost-effectiveness of low-dose colchicine therapy in patients with chronic coronary disease when added to standard background therapy.

Pregnancy and the risk of torsades de pointes in congenital long-QT syndrome.

Patients with congenital long-QT syndrome (LQTS) are at increased risk of ventricular arrhythmias during stressful situations. Large-scale studies have pointed out that affected individuals are particularly at risk in the period following pregnancy (post-partum). This is recognised especially for women with an LQTS type 2.

High-dose testosterone is associated with atherosclerosis in postmenopausal women.

Objectives: To study the long-term effects of androgen treatment on atherosclerosis in postmenopausal women.

Methods: In a population-based study in 513 naturally postmenopausal women aged 54-67 years, we studied the association between self-reported intramuscularly administered high-dose estrogen-testosterone therapy (estradiol- and testosterone esters) and aortic atherosclerosis. Aortic atherosclerosis was diagnosed by radiographic detection of calcified deposits in the abdominal aorta, which have been shown to reflect intima atherosclerosis.

Double orifice mitral valve; a coincidental finding.

A double orifice mitral valve (DOMV) represents a rare congenital malformation characterised by two valve orifices with two separate subvalvular apparatus. This case demonstrates the necessity of careful imaging of the mitral valve apparatus, not only in patients with atrioventricular septal defects, but also in patients with congenital left obstructive heart disease.

Moraxella catarrhalis sepsis in a patient with juvenile spinal muscle atrophy.

Moraxella catarrhalis rarely causes severe infections or bacteraemia in healthy subjects. In the literature only four cases of clinical sepsis with M. catarrhalis have been described, mostly in immunocompromised patients.

Complete versus culprit vessel percutaneous coronary intervention in multivessel disease: a randomized comparison.

Background: The purpose of this study was to compare the safety, efficacy, and costs of complete versus "culprit" vessel revascularization in multivessel coronary artery disease treated with percutaneous coronary interventions (PCI).

Methods: Patients with multivessel disease and an identified culprit vessel were randomly assigned to complete revascularization of vessels > or =50% stenoses (n = 108) versus revascularization limited to the culprit vessel (n = 111). The primary end point, major adverse cardiac events (MACE), were defined as cardiac or noncardiac death, myocardial infarction, need for coronary artery bypass graft surgery, and repeat PCI up to 1 year.

Lack of efficacy of clopidogrel pre-treatment in the prevention of myocardial damage after elective stent implantation.

Objectives: The object of this study was to determine the effect of pre-treatment with clopidogrel in patients undergoing elective stent implantation.

Background: The treatment of patients with adenosine diphosphate receptor blockers after percutaneous coronary intervention (PCI) with stent implantation has been shown to decrease the incidence of subacute stent thrombosis. Furthermore, non-randomized studies on pre-treatment with clopidogrel among patients undergoing stent implantation have suggested a reduction in myocardial damage and clinical events.

Parity and carotid artery atherosclerosis in elderly women: The Rotterdam Study.

Background And Purpose: It has been postulated that physiological changes in the cardiovascular system, lipids, and glucose metabolism during pregnancy may increase subsequent risk of cardiovascular disease. Examination of the association between parity and risk factors for atherosclerosis may contribute information regarding possible mechanisms.

Methods: The relationship of parity with cardiovascular risk factors and the presence of carotid atherosclerosis was examined in the Rotterdam Study, a population-based study comprising 4878 women aged 55 years and older.

Oestrogen, atherosclerosis and cardiovascular disease in women: Epidemiological studies on menopause and hormone replacement therapy.

What part menopause and hormone replacement therapy (HRT) play in the risk of cardiovascular disease in women after middle-age is still debated. The associations between menopause, HRT and cardiovascular disease as well as atherosclerosis were examined in a large cohort study. Our results suggest menopause has an unfavorable association with several cardiovascular risk factors, structural characteristics of the large arteries, on atherosclerosis and on coronary heart disease.

Is open-angle glaucoma associated with early menopause? The Rotterdam Study.

The authors examined the association between age at menopause and open-angle glaucoma among women aged > or = 55 years in the population-based Rotterdam Study (1990--1993). Information on age and type of menopause was obtained by interview. Subjects (n = 3,078) were stratified into three categories according to age at menopause: <45 years, 45--49 years, and > or = 50 years, with the last group serving as the reference group.

Direct coronary stent implantation: safety, feasibility, and predictors of success of the strategy of direct coronary stent implantation.

This prospective study was designed to evaluate the feasibility, safety, predictive factors of success, and 6-month follow-up of stent implantation without balloon predilatation (direct stenting) in 250 patients undergoing elective stent implantation. Balloon dilatation prior to stent implantation was a prerequisite to facilitate passage and deployment of the stent. Stent technology has changed tremendously, resulting in stents with improved properties, which may allow stent placement without prior balloon dilatation.

The effect of hormone replacement therapy on arterial distensibility and compliance in perimenopausal women: a 2-year randomised trial.

A single centre randomised placebo-controlled trial was performed to assess the 2-year effects of hormone replacement therapy compared to placebo on mechanical arterial properties in 99 perimenopausal women recruited from the general population. The trial was double-blind with respect to a sequential combined regimen of oral 17beta-oestradiol and desogestrel (17betaE(2)-D) and the placebo group and open with respect to combination of conjugated equine oestrogens and norgestrel (CEE-N). At baseline, distensibility and compliance of the common carotid artery were measured non-invasively with B-mode ultrasound and a vessel wall movement detector system, and the distensibility coefficient (DC) and compliance coefficient (CC) were calculated.

Hormone replacement therapy and peripheral arterial disease: the Rotterdam study.

Background: As the number of elderly women increases in Western society, peripheral arterial disease (PAD) is likely to become an increasing problem. Hormone replacement therapy, suggested to protect against coronary atherosclerosis, might also inhibit the development of PAD.

Methods: The association between hormone replacement therapy and the presence of PAD was studied in a population-based study consisting of 2196 naturally menopausal women aged 55 to 80 years living in a suburban area of Rotterdam, the Netherlands.

Variables of the insulin resistance syndrome are associated with reduced arterial distensibility in healthy non-diabetic middle-aged women.

Aims/hypothesis: The insulin resistance syndrome is related to arterial stiffness in diabetic subjects. Whether the insulin resistance syndrome is also related to arterial stiffness in non-diabetic subjects is less clear. We studied the association between variables of the insulin resistance syndrome in relation to arterial distensibility in healthy middle-aged non-diabetic women.

Increased plasma homocysteine after menopause.

Besides genetic defects in the enzymes involved in homocysteine metabolism and nutritional deficiencies in vitamin cofactors, sex steroid hormones may modulate plasma homocysteine levels. The post-menopausal state has been found to be associated with higher plasma homocysteine levels, but data are inconsistent and studies published so far did not adjust for age, which is an important confounding factor in studying the effect of menopause. In the present study total plasma homocysteine levels were measured in a meticulously selected population in which the contrast in estrogen status between pre- and postmenopausal women of the same age was maximized.

Menopausal status and risk factors for cardiovascular disease.

Objectives: Changes in cardiovascular risk factors with menopausal status are difficult to study, owing to the high correlation of menopausal status with age. Therefore we examined cardiovascular risk factors in a meticulously selected population in which the contrast in oestrogen status between pre- and postmenopausal women of the same age was maximized.

Design: Risk factors were compared in 93 premenopausal and 93 postmenopausal women who were matched on age (range 43-55 years).

Hormone replacement therapy and intima-media thickness of the common carotid artery: the Rotterdam study.

Background And Purpose: Observational data suggest that hormone replacement therapy (HRT) reduces morbidity and mortality from cardiovascular disease in healthy postmenopausal women. The mechanisms underlying this protection are not entirely clear but may include inhibition of the atherosclerotic process.

Methods: We studied the association between ever use of HRT and intima-media thickness (IMT) of the common carotid artery in 1103 naturally menopausal women, aged 55 to 80 years, in the Rotterdam Study, a community-based cohort study in a suburban area of Rotterdam, Netherlands.

Hormone replacement therapy in perimenopausal women and 2-year change of carotid intima-media thickness.

Objectives: To assess the 2-year effects of a combined regimen of oral 17beta-estradiol and desogestrel (17betaE-D) and a sequential combination of conjugated equine estrogens and norgestrel (CEE-N) on common carotid intima-media thickness and end-diastolic lumen diameter in comparison to placebo in perimenopausal women.

Methods: The study was a single center, randomized, group-comparative, double-blind study with respect to the 17betaE-D and placebo groups and open with respect to CEE-N. After cycle 6, the blind was broken and the trial was continued as an open trial for another 18 months for the active study arms.

Estrogen receptor polymorphism predicts the onset of natural and surgical menopause.

Age at menopause and risk of hysterectomy have strong genetic components, but the genes involved remain ill defined. We investigated whether genetic variation at the estrogen receptor (ER) gene contributes to the variability in the onset of menopause in 900 postmenopausal women, aged 55-80 yr, of the Rotterdam Study, a population-based cohort study in The Netherlands. Gynecological information was obtained, and if women reported surgical menopause, validation of type and indication of surgery was accomplished by checking medical records.

Associations of C-reactive protein with measures of obesity, insulin resistance, and subclinical atherosclerosis in healthy, middle-aged women.

Obesity, the insulin resistance syndrome, and atherosclerosis are closely linked and may all be determinants of an increased acute-phase response. In this study, we examined the relationship of C-reactive protein (CRP) with measures of obesity, variables of the insulin resistance syndrome, and intima-media thickness of the common carotid arteries in 186 healthy, middle-aged women selected from the general population. Associations were assessed by regression analysis.

Menopausal status and distensibility of the common carotid artery.

Although several studies have shown that exogenous estrogens have beneficial effects on arterial characteristics, the effect of endogenous estrogen on the vascular system is still unknown. In this study, distensibility, an indicator of arterial elasticity, of the common carotid artery was compared in pre- and postmenopausal women. The study comprised 93 premenopausal and 93 postmenopausal women of similar age (range, 43 to 55 years).

Prevalence of Asherman's syndrome after secondary removal of placental remnants or a repeat curettage for incomplete abortion.

This prospective study assesses the prevalence of intrauterine adhesions among women undergoing secondary removal of placental remnants after delivery, or a repeat curettage for incomplete abortions, and evaluates risk factors associated with the presence of intrauterine adhesions. In 50 women, undergoing either a secondary removal of placental remnants more than 24 h after delivery, or a repeat curettage for incomplete abortions, ambulatory hysteroscopy was performed 3 months after the intervention. Intrauterine adhesions were found in 20 of the women (40%): five patients had Asherman's syndrome grade I, six had grade II, six had grade III and three had grade IV.
