JNC-7 guidelines: Are they still relevant?

One more look at guidelines for primary and secondary prevention of cardiovascular disease in women

The most common cause of death in menopausal women is due to complications from cardiovascular disease. However, many physicians feel that the prevention in women may be delayed, because women present the clinical manifestations of cardiovascular disease 10 years later than men. Another matter emerged following the results of the Women's Health Initiative study and of the Heart Estrogen/Progestin Replacement Study. Thus the proper interpretation and implementation of science should be included in a strict procedure of appreciation and clear communication for both the qualitative and quantitative evaluation of evidence, used for the clinical guidelines. Based on objective scientific collaboration among various specialities, guidelines for the prevention of cardiovascular disease of adult women with a broad range of cardiovascular risk have been formed. In this review, the guidelines or recommendations which have been reported in the last 2 decades by various scientific societies for prevention of cardiovascular disease in women will be analysed.

Hypertension: how does management change with aging?

Hypertension is a significant risk factor for cardiovascular morbidity and mortality in people older than 60 years. Isolated systolic hypertension and widened pulse pressure appear to be more important than diastolic hypertension. Very low blood pressure and orthostatic hypotension are associated with increased mortality, and should be checked for at every visit. Best evidence suggests that adjusting hypertension goals with age, and starting therapy when blood pressure is greater than 160/90 leads to improved outcomes. Therapy should start with a thiazide diuretic (best evidence) or an angiotensin-converting enzyme inhibitor.

Assessment of cardiovascular risk and prevention of cardiovascular disease in women with the polycystic ovary syndrome: a consensus statement by the Androgen Excess and Polycystic Ovary Syndrome (AE-PCOS) Society

OBJECTIVE

Women with polycystic ovary syndrome (PCOS) often have cardiovascular disease (CVD) risk factors. The Androgen Excess and Polycystic Ovary Syndrome (AE-PCOS) Society created a panel to provide evidence-based reviews of studies assessing PCOS-CVD risk relationships and to develop guidelines for preventing CVD.

PARTICIPANTS

An expert panel in PCOS and CVD reviewed literature and presented recommendations.

EVIDENCE

Only studies comparing PCOS with control patients were included. All electronic databases were searched; reviews included individual studies/databases, systematic reviews, abstracts, and expert data. Articles were excluded if other hyperandrogenic disorders were not excluded, PCOS diagnosis was unclear, controls were not described, or methodology precluded evaluation. Inclusion/exclusion criteria were confirmed by at least two reviewers and arbitrated by a third.

CONSENSUS PROCESS

Systematic reviews of CVD risk factors were compiled and submitted for approval to the AE-PCOS Society Board.

CONCLUSIONS

Women with PCOS with obesity, cigarette smoking, dyslipidemia, hypertension, impaired glucose tolerance, and subclinical vascular disease are at risk, whereas those with metabolic syndrome and/or type 2 diabetes mellitus are at high risk for CVD. Body mass index, waist circumference, serum lipid/glucose, and blood pressure determinations are recommended for all women with PCOS, as is oral glucose tolerance testing in those with obesity, advanced age, personal history of gestational diabetes, or family history of type 2 diabetes mellitus. Mood disorder assessment is suggested in all PCOS patients. Lifestyle management is recommended for primary CVD prevention, targeting low-density and non-high-density lipoprotein cholesterol and adding insulin-sensitizing and other drugs if dyslipidemia or other risk factors persist.

Influence of Aging and Menopause on Lipids and Lipoproteins in Women

The actions of endogenous estrogens on the cardiovascular system can be mediated directly on the vessels or indirectly through the modulation of cardiovascular risk factors. Aging and menopause are the main causes that lead to an adverse lipid profile in women. The influence of age on prevalence of increased plasma triglyceride levels and on larger variation in fasting triglyceride levels has been reported in both genders. However, the increased prevalence of increased cholesterol with age was only found in women. The high-density lipid cholesterol level is higher in women than in men throughout all ages. Obesity may also exaggerate the unfavorable lipid profile in aging and/or menopausal women. In the last decades the management of the menopausal women has been a subject of concern for medical scientific groups. In this review, the current understanding of an influence of age and menopause on lipids and lipoproteins concentration in women will be analyzed.
