Subjective memory complaints and incident dementia in a high risk older adult hypertensive population.

BACKGROUND: there is a growing body of evidence demonstrating an association between subjective memory complaints (SMC) and an increased risk of incident cognitive decline or dementia. To date this has not been examined in hypertensive older adults, a prevalent and growing population group at high risk of cognitive decline. METHODS: using data from participants in the Hypertension in the Very Elderly Trial cohort the association between baseline SMC and incident cognitive decline and dementia was examined using Cox proportional hazard regression. Cognitive function was assessed using the Mini-Mental State Exam and diagnoses of dementia were made using standard diagnostic criteria. SMC was assessed by the question 'do you feel that you have more problems with memory than most?' Analyses were rerun to examine the associations by level of baseline cognitive function, to evaluate the role of SMC by dementia type and by sex. RESULTS: baseline SMC were associated with an increased risk of developing any dementia (hazard ratio (HR)1.63 (95% confidence intervals (CI): 1.18:2.25)), Alzheimer's disease (HR1.59 (95% CI: 1.08:2.34)) and vascular dementia (HR2.05 (95% CI: 1.19:3.54)). Similar patterns were seen across all levels of baseline MMSE but were strongest in those with scores of 25-27. There were no clear differences by sex. DISCUSSION: a positive report of SMC assessed by a single question in an older adult with hypertension raises the possibility of increased risk of incident dementia. As such its use may be a useful addition to the repertoire of the general practitioner and geriatrician when assessing older adults.

Arterial compliance may be reduced by ingestion of red wine.

The aim of this study was to assess the effect of alcohol on blood pressure and arterial compliance over 24 h in a group of volunteers, comparing the same group of subjects on two consecutive but separate days, one with alcohol intake (alcohol day) and one free of alcohol (control day). We studied 18 healthy subjects (mean age 34.2 years, range 25-53). The subjects received the two days in random order. On the alcohol day, the subjects were asked to drink two glasses of red wine (12% ethanol) between 1830 hours and 0430 hours. Measurements of heart rate, blood pressure and QKD interval (Q wave to Korotkoff (K) sound, diastolic phase (D) using Diasys Integra (Novacor, France)) were recorded (usually 1500 hours to 1500 hours). Three 'ingestion' periods were defined, from 1500 hours to 1830 hours ('before'), 1900 hours to 0430 hours ('during') and from 0430 hours to the following afternoon ('after') on both the alcohol day and on the control day. Red wine increased heart rate during alcohol ingestion and reduced arterial compliance after ingestion. The significant effect of interaction between day and ingestion period on heart rate, diastolic blood pressure and QKD were found, suggesting that the differences in response among the ingestion periods depended on whether alcohol has been consumed that day. For the first time our study indicates the effect of alcohol on 24 h arterial stiffness in a healthy group of volunteers.

Blood pressure control in the Hypertension in the Very Elderly Trial (HYVET).

To report blood pressure control in the Hypertension in the Very Elderly Trial, a placebo-controlled trial of hypertensive (systolic blood pressure (SBP) 160-199 mm Hg, diastolic blood pressure (DBP) <110 mm Hg) participants over the age of 80 years, given treatment in three steps: indapamide slow release 1.5 mg alone, indapamide plus 2 mg perindopril and indapamide plus 4 mg perindopril. The difference in control between participants with combined systolic and diastolic hypertension (SDH, DBP90 mm Hg) and those with isolated systolic hypertension (ISH, DBP<90 mm Hg) is determined together with the effects of increments in the treatment regimen. At 2 years, the active treatment lowered blood pressure by 16.5/6.9 mm Hg more than that on placebo in participants with SDH and by 19.3/4.8 mm Hg more in those with ISH. The 2-year falls in pressure on placebo alone were 13.2/8.5 mm Hg in SDH and 8.2/1.5 mm Hg in ISH participants. With full titration of active treatment, 62% of SDH participants achieved goal SBP (<150 mm Hg) by 2 years and 71% of those with ISH. The corresponding results for DBP control (<80 mm Hg) were 40 and 78%. The addition of active perindopril 2 mg roughly doubled the percentage controlled, as did increasing to 4 from 2 mg. Blood pressure control was good with ISH and better than with SDH. The fall in SBP accounted for the observed 30% reduction in strokes, but the 21% reduction in total mortality and 64% reduction in heart failure were greater than predicted.

Self management and patient understanding of diabetes in the older person.

AIM: To examine knowledge and management of diabetes by older people. METHODS: A representative sample of 1047 people with Type 2 diabetes, aged 75 years and over, were asked a series of questions relating to their diabetes management and their understanding of self management. The impact of cognitive impairment and socio-economic status were assessed. RESULTS: The majority of people, 1015 (96.9%), were under the care of a health professional and 1018 (97.2%) were taking insulin, tablets, controlling their diet or a combination. Cognitive impairment (Mini-Mental State Examination ≤ 23) was found in 235 (22.5%) people. Recent eye, foot and dietician assessment was reported by 813 (77.7%), 836 (79.7%) and 326 (31.1%) people, respectively. A quarter overall and 70% of those taking insulin tested their blood glucose. In the insulin group, 78 (54.2%) reported hypoglycaemia and those with cognitive impairment gave more incorrect responses when asked about diabetes management. Socio-economic status made very little difference to any of these outcomes. CONCLUSIONS: Most older people with diabetes, regardless of their socio-economic status, are under the care of a healthcare professional and use medication or diet to manage their disease. Large numbers also attend foot and eye examinations. However, over one fifth of older people with diabetes have cognitive impairment. Older people had a reasonable understanding of their diabetes management but this was worse in those people with cognitive impairment.

The prevalence of Type 2 diabetes and its associated health problems in a community-dwelling elderly population.

AIMS: Prevalence estimates of Type 2 diabetes and its associated health problems in elderly populations are rare, especially in the very elderly. METHODS: A sample of 15 095 community-dwelling older people aged > or = 75 years were assessed. Type 2 diabetes and associated health problems were identified using self-reporting, general practitioner records, drug histories, and blood and urine measurements. RESULTS: There were 1177 people identified as having Type 2 diabetes mellitus, giving an overall prevalence of 7.8% (95% confidence interval 7.1, 8.5), 9.4% (8.4, 10.5) for men and 6.8% (6.1, 7.6) for women. The age, sex and smoking adjusted odds ratios for various health problems, comparing people with and without diabetes were: low vision 1.6 (1.3, 1.9), proteinuria 1.7 (1.4, 2.1), chronic kidney disease stage 4 or 5 1.5 (1.0, 2.1), angina 1.3 (1.1, 1.6), myocardial infarction 1.5 (1.2, 1.8), cerebrovascular event 2.0 (1.8, 2.1) and foot ulceration 1.7 (1.2, 2.4). CONCLUSIONS: The prevalence of Type 2 diabetes is not high in community-dwelling older people, but diabetes was a contributory factor to a number of health problems.

Left ventricular hypertrophy by Sokolow-Lyon voltage criterion predicts mortality in overweight hypertensive subjects.

In view of the low sensitivity of Sokolow-Lyon voltage criteria in the assessment of electrocardiographic left ventricular hypertrophy (ECG LVH) in overweight subjects, we determined its clinical utility in 1840 lean and 3555 overweight subjects with hypertension. They were followed prospectively over an average of 11 years by the Department of Health and Social Security Hypertension Care Computer Project. LVH was determined at baseline using the Sokolow-Lyon criterion that is, the amplitude voltage SV1+(max RV5 or RV6) > or =3.5 mV. Overweight status was defined as body mass index (BMI) > or =25 kg m(-2). Prevalence of ECG LVH was 16% in lean and 12% in overweight women, 35 and 20% in lean and overweight men. For each 0.1 mV increase in ECG voltage as a continuous variable, the age and sex adjusted risk of stroke, coronary heart disease and cardiovascular disease (CVD) mortality increased significantly by 3.0, 1.5 and 1.8% in overweight subjects and by 2.8, 1.8 and 2.4% in lean subjects. After additional adjustments for smoking, blood glucose and serum cholesterol concentration in a subgroup of 654 lean and 1281 overweight subjects with complete information on these variables, an increasing voltage still significantly predicted stroke and CVD mortality in overweight subjects. The excess high risk of dying was evident especially in women with LVH in the highest BMI quartiles. When ECG detects LVH in overweight subjects, it is a good predictor of mortality despite the lower sensitivity in this group.

Left ventricular hypertrophy determined by Sokolow-Lyon criteria: a different predictor in women than in men?

The clinical usefulness of the Sokolow-Lyon voltage criteria in the assessment of electrocardiographic left ventricular hypertrophy (ECG LVH) is addressed. We prospectively studied 3,338 women and 3,330 men referred with hypertension, with an average follow-up of 11.2 years. The voltage amplitude sum SV1+max (RV5 or RV6) was calculated and ECG LVH was defined as a sum >or=3.5 mV. We adjusted survival for age, treatment status before presentation and a previous myocardial infarction or cerebrovascular accident. The risk of stroke, coronary heart disease (CHD) and cardiovascular disease (CVD) mortality increased significantly for each quantitative 0.1 mV increase in baseline electrocardiogram (ECG) voltage, in women within the range of 1.6-3.9% and in men 1.4-3.0%. After further adjustments for race, body mass index, smoking and systolic blood pressure, increasing voltage independently predicted CVD mortality in both men and women. In women, both increasing voltage and the presence of left ventricular hypertrophy (LVH) were predictors of stroke mortality, whereas in men this risk was attenuated. In men, the adjusted association between increasing voltage and CHD mortality tended to be stronger than in women. The use of different thresholds for the two genders made little difference. For stroke and CHD mortality, the population attributable fractions associated with LVH were 15.2 and 5.4% in women and 12.8 and 8.5% in men, respectively. In conclusion, the greater the baseline ECG voltage sum, the greater the associated CVD mortality risk. Women tended to have a high risk of stroke mortality owing to LVH despite adjustments.

Romanian subjects entered in the hypertension in the very elderly trial (HYVET).

The baseline characteristics, possibly related to cardiovascular outcome, in 94 Romanian hypertensive men and 168 women over the age of 80 entered into the Hypertension in the Very Elderly Trial (HYVET) were compared with those in 725 men and 1128 women entered into the trial in the rest of Western and Eastern Europe (mainly Russia and Bulgaria). There was a tendency for more women in the Romanian subjects (66.7% versus 60.9% (P = 0.08)) and therefore all comparisons were adjusted for this non significant difference. The Romanian subjects were slightly younger, had more previous hypertension, but more previous strokes than the rest of Europe, and consumed a similar amount of alcohol. The Romanian subjects were, on average, lighter and shorter. Romanians had higher mean concentrations of blood urea and glucose and higher concentrations of HDL cholesterol. Total cholesterol was, on average, lower in Romanian subjects than was serum creatinine. Serum sodium, blood hematocrit and hemoglobin were all, on average, lower in Romanian subjects. The Romanian subjects were recruited from predominantly rural areas and it is hypothesised that their diet may have contained less salt, iron and other haematinics. Calorie restriction, compared to the rest of Europe, may have resulted in lower stature and weight but recent increases in calorie intake may have resulted in the increasing average blood glucose in both sexes. DDT is known to block the uptake of HDL cholesterol by the liver and may explain the increased HDL concentrations in Romania. Some of these biochemical differences may reflect different methodologies employed in Romanian laboratories, but we could not confirm this possibility.

Differences in the association between type 2 diabetes and impaired microvascular function among Europeans and African Caribbeans.

AIMS/HYPOTHESIS: Diabetes is associated with microvascular damage in all populations, but diabetic patients of Black African descent (African Caribbeans) have a greater risk of vascular target organ damage than would be anticipated for any given blood pressure level. We investigated whether this may be due to differences in the microvasculature. MATERIALS AND METHODS: To assess the maximum hyperaemic response to heating and the post-ischaemic response, Laser Doppler fluximetry was performed on 51 and 100 Europeans, and on 66 and 88 African Caribbeans with and without diabetes, respectively. Subjects were aged between 40 and 65 years and recruited from the general population. Echocardiographic interventricular septal thickness (IVST) was measured as a proxy for vascular target organ damage. RESULTS: In diabetic subjects of both ethnic groups, the maximum hyperaemic response and peak response to ischaemia were attenuated as compared to the corresponding non-diabetic subjects (p=0.08 for diabetic and 0.03 for non-diabetic Europeans; p=0.03 and 0.1 for African Caribbeans). Adjustment for cardiovascular risk factors, in particular insulin and blood pressure, abolished these differences in Europeans (p=0.8 for diabetic and 0.2 for non-diabetic Europeans), but not in African Caribbeans (p=0.03 and 0.05). CONCLUSIONS/INTERPRETATION: Persisting microvascular dysfunction in African Caribbeans may contribute to the increased risk of target organ damage observed in diabetes in this population. The weak contribution of conventional cardiovascular risk factors to these disturbances indicates that conventional therapeutic interventions may be less beneficial in these patients. There was a risk-factor-independent, inverse association between IVST and maximal hyperaemia. These ethnic differences in microvascular responses to temperature and arterial occlusion could account for increased target organ damage in African Caribbeans.

Respiratory symptoms in older people and their association with mortality.

BACKGROUND: A study was undertaken to assess the prevalence of reported respiratory symptoms in a population aged over 75 years and their association with mortality. METHODS: A total of 14 458 people aged 75 years and over participating in a trial of health screening of older people in general practice answered questions on three respiratory symptoms: cough, sputum production, and wheeze. The association of symptoms with mortality was examined for all cause and respiratory causes of death taking account of potential confounders. RESULTS: Coughing up phlegm in winter mornings had a prevalence of 27.0% (95% confidence interval (CI) 26.8 to 27.2). Those with this symptom had an adjusted hazard ratio for all cause mortality of 1.35 (95% CI 1.21 to 1.50), p<0.001 and for respiratory specific mortality of 2.01 (95% CI 1.66 to 2.41), p<0.001. Phlegm at any time of the day in winter had a prevalence of 16.5% (95% CI 16.3 to 16.7) with hazard ratios for all cause and respiratory specific mortality of 1.28 (95% CI 1.15 to 1.42) and 2.28 (95% CI 1.92 to 2.70), p<0.001. Wheeze or whistling from the chest had a prevalence of 14.3% (95% CI 14.1 to 14.5) with hazard ratios of 1.45 (95% CI 1.31 to 1.61) and 2.86 (95% CI 2.45 to 3.35), p<0.001. CONCLUSIONS: The prevalence of respiratory symptoms is widespread among elderly people and their presence is a strong predictor of mortality.

Transiently elevated diastolic blood pressure is associated with a gender-dependent effect on cardiovascular risk.

We assessed the morbidity and mortality of subjects with transiently elevated diastolic pressure in the General Practice Hypertension Study Group (GPHSG) population. A total of 23 578 patients (aged 18-65 years) from seven UK general practices were screened in 1974 for a diastolic blood pressure (DBP4) of > or = 90 mmHg. Two further readings of DBP4 determined hypertensive (either DBP4 > or = 90 mmHg) or transient hypertensive (both DBP4 < 90 mmHg) status. Transients (n = 850) were matched with normotensive controls (n = 824) and risk ratios calculated over a mean follow-up of 18.7 years. Rescreening was conducted in six of the practices (n = 20 942) after 7.7 years. Male transients had a higher relative hazard for cardiovascular mortality than controls (11.8%, 8.6%, adjusted relative hazard 1.59, P = 0.056). Female transients had a lower relative hazard for cardiovascular mortality than controls (3.6%, 5.4%, adjusted relative hazard 0.39, P = 0.018). In all, 422 patients with transient hypertension were rescreened along with 367 matched controls. Significantly more transients were on antihypertensive treatment compared with their controls (odds ratio (OR) [95% CI]) for both male (4.2 [1.6-11.1]) and female patients (2.4 [1.0-5.56]) and more untreated female transients developed hypertension. Male transients had a higher rates of diabetes mellitus (adj OR = 5.1, P = 0.04) and stroke (adj OR 15.9, P = 0.03). This study has shown that transiently elevated DBP in GPHSG is associated with a significantly higher risk of later hypertension in men and women and of diabetes, stroke and cardiovascular mortality in men. Women with this condition have a significantly lower cardiovascular mortality.

Area deprivation, social class, and quality of life among people aged 75 years and over in Britain.

BACKGROUND: There is a shortage of research studies that assess how selected characteristics of neighbourhood and personal social circumstances contribute towards health-related quality of life (QoL) among older people. METHODS: Analysis of baseline data for 5581 people aged > or =75 years and over from the Trial of Assessment and Management of Older People in the Community. The scores for four dimensions from the UK version of the Sickness Impact Profile and for the Philadelphia Geriatric Morale Scale were analysed in relation to individual social class and the Carstairs score of socioeconomic deprivation for the enumeration district of residence. RESULTS: In age and sex adjusted analyses, the proportion of participants of social class IV/V living in the most deprived areas who were in the quintile with worst QoL scores was more than double that among those from social class I/II living in the least deprived areas. Individual social class and area deprivation score contributed roughly equally to this doubling for home management, self-care and social interaction, whereas social class appeared a stronger determinant for mobility. Adjustment for living circumstances, health symptoms, and health behaviours substantially reduced the excess risk associated with social class and area deprivation. Being in a rural area was associated with lower risk of poor morale. CONCLUSION: Poor socioeconomic characteristics of both the area and the individual are associated with worse functioning (QoL) of older people in the community. This is not fully explained by health status. Policy should consider community-level interventions as well as those directed at individuals.

The determinants of left ventricular hypertrophy defined by Sokolow-Lyon criteria in untreated hypertensive patients.

Left ventricular hypertrophy (LVH) measured by electrocardiography (ECG LVH) in hypertensive patients has been shown to be associated with an increased risk of cardiovascular sequelae. Analysis of the determinants predisposing to ECG LVH may be helpful in the prevention of LVH. The Department of Health and Social Security Hypertension Care Computer Project studied 2994 hypertensive patients in whom an electrocardiogram was recorded while not on treatment. LVH was determined as the voltage sum SV1+RV5 or RV6>or=35 mm using Sokolow-Lyon voltage criteria. The relations were determined between the presence of LVH or voltage sum and different variables. Untreated systolic (SBP) and diastolic (DBP) blood pressure and pulse pressure were positively related to the increasing ECG voltage, while body mass index (BMI) and serum cholesterol were inversely related. Blood glucose and age did not correlate significantly. Patients with the presence of ECG LVH were more often men, black people, smokers and users of alcohol. In multiple logistic regression analyses, SBP, DBP, male gender and black race were positively, whereas BMI was negatively related to the presence of LVH. The positive relation of smoking and negative relation of serum cholesterol concentration to the presence of ECG LVH were apparent in men but not in women. This study confirms the adverse association between ECG LVH and SBP and DBP, male gender, black race and decreased BMI. It also addresses the less well-known associations of blood glucose, cholesterol, smoking and alcohol consumption.

The MRC trial of assessment and management of older people in the community: objectives, design and interventions [ISRCTN23494848].

BACKGROUND: The benefit of regular multidimensional assessment of older people remains controversial. The majority of trials have been too small to produce adequate evidence to inform policy. Despite the lack of a firm evidence base, UK primary care practitioners (general practitioners) are required to offer an annual health check to patients aged 75 years and over. DESIGN: Cluster-randomised factorial trial in primary care comparing a package of assessments (i) universal versus targeted assessment and (ii) management by the primary care team (PC) or a multidisciplinary geriatric assessment team (GM). The unit of randomization is the general practice. METHODS: Older people aged 75 and over eligible for the over 75s health check and excluding those in nursing homes or terminally ill were invited to participate. All participants receive a brief assessment covering all areas of the over 75s check. In the universal arm all participants also receive a detailed health and social assessment by a study nurse while in the targeted arm only participants with a pre-determined number and range of problems at the brief assessment go on to have the detailed assessment. The study nurse follows a standard protocol based on results and responses in the detailed assessment to make referrals to (i) the randomised management team (PC or GM) (ii) other medical services, health care workers or agencies (iii) emergency referrals to the GP. The main outcomes are mortality, hospital and institutional admissions and quality of life. 106 practices and 33,000 older people have been recruited to the trial.

Selective recording in blood pressure readings may increase subsequent mortality.

BACKGROUND: Rounding blood pressure (BP) to the nearest 10 mmHg (terminal digit preference) and selecting for particular values near treatment cut-offs (number preference) have both been previously described. Both reduce measurement accuracy, and may have consequences for treatment and survival. AIM: To check for number preference in screening for hypertension, and whether this influenced subsequent mortality. DESIGN: Prospective case-control screening study. METHODS: In the General Practice Hypertensive Study Group (GPHSG), prospective case control study patients (n=23 574) were screened on one occasion for high phase-IV diastolic BP (DBP4) (> or =90 mmHg). Identified cases were matched with normotensive controls for age, sex, date of screen and ethnic group, and were registered for mortality follow-up (n=6310). Patients with a high DBP4 had two further readings, and were treated if it remained elevated. RESULTS: For DBP4 terminal digit, '0' was over-represented (28.2% vs. 20%), and the number '88' was over-represented in both men and women. There was an excess adjusted death rate for females with DBP4 88-89 mmHg vs. 90-99 mmHg for both cardiovascular (RR 2.56, 95%CI 1.43-4.56, p=0.0015) and all-cause (1.56, 95%CI 1.06-2.29, p=0.023) mortality. For males, the corresponding rates were non-significantly reduced: cardiovascular RR 0.69, 95%CI 0.42-1.14, p=0.15; all-cause RR 0.93, 95%CI 0.68-1.27, p=0.64. DISCUSSION: The quality of BP measurements should be monitored both in research studies and in clinical practice as part of clinical governance procedures.

Prevalence of visual impairment in people aged 75 years and older in Britain: results from the MRC trial of assessment and management of older people in the community.

AIMS: To measure the prevalence of visual impairment in a large representative sample of people aged 75 years and over participating in the MRC trial of assessment and management of older people in the community. METHODS: 53 practices in the MRC general practice research framework. Data were obtained from 14 600 participants aged 75 years and older. Prevalence of visual impairment overall (binocular visual acuity <6/18) which was categorised separately into low vision (binocular visual acuity <6/18-3/60) or blindness (binocular visual acuity of <3/60). The prevalence of binocular acuity <6/12 was presented for comparison with other studies. Visual acuity was measured using Glasgow acuity charts; glasses, if worn, were not removed. RESULTS: Visual acuity was available for 14 600 people out of 21 241 invited (69%). Among people with visual acuity data, 12.4% overall (1803) were visually impaired (95% confidence intervals 10.8% to 13.9%); 1501 (10.3%) were categorised as having low vision (8.7% to 11.8%), and 302 (2.1%) were blind (1.8% to 2.4%). At ages 75-79, 6.2% of the cohort were visually impaired (5.1% to 7.3%) with 36.9% at age 90+ (32.5% to 41.3%). At ages 75-79, 0.6% (0.4% to 0.8%) of the study population were blind, with 6.9% (4.8% to 9.0%) at age 90+. In multivariate regression, controlling for age, women had significant excess risk of visual impairment (odds ratio 1.43, 95% confidence interval 1.29 to 1.58). Overall, 19.9% of study participants had a binocular acuity of less than 6/12 (17.8% to 22.0%). CONCLUSION: The results from this large study show that visual impairment is common in the older population and that this risk increases rapidly with advancing age, especially for women. A relatively conservative measure of visual impairment was used. If visual impairment had been defined as visual acuity of <6/12 (American definition of visual impairment), the age specific prevalence estimates would have increased by 60%.

Testosterone suppression in men with prostate cancer is associated with increased arterial stiffness.

Low androgen levels in men are associated with increased cardiovascular risk, through unclear mechanisms. We measured arterial stiffness ('compliance') in 21 men receiving complete testosterone suppression therapy for prostate cancer, and in 25 controls. Systemic arterial compliance (SAC), which assesses proximal aortic stiffness, was calculated by simultaneous recording of aortic flow and carotid artery pressure (the 'area method'). Aorto-femoral (A-F), aorto-radial (A-R) and femoral-dorsalis pedis (F-DP) pulse-wave velocities (PWVs) were recorded using the 'Complior' system. SAC was significantly lower in the androgen-depleted men compared to controls (0.81 +/- 0.53 vs. 1.18 +/- 0.43 arbitrary compliance units, p = 0.01, mean +/- SD). Correspondingly, their A-F PWV was higher (14.1 (10.1-21.8) vs. 12.4 (9.6-17.4) m/s, p = 0.03, median (range)). Cases tended to be older (75 +/- 7 vs. 71 +/- 6 years, p = 0.07), and to have higher systolic blood pressure (148 +/- 22 vs. 143 +/- 17 mmHg, p = 0.40); however, SAC was still significantly lower (p = 0.03) after adjustment for age and stratification for central systolic pressure (< or = or > the median). Adjustment of A-F PWV for age and central systolic pressure reduced significance to p = 0.07. There was no significant difference in peripheral PWVs between groups. In conclusion, testosterone suppression is associated with increased aortic stiffness, only partly explained by age and blood pressure. Loss of androgens in men might therefore adversely affect cardiovascular risk.
