Fall prevention in the young old using an exoskeleton human body posturizer: a randomized controlled trial.

BACKGROUND: Fall risk in elderly has been related with physical decline, low quality of life and reduced survival. AIM: To evaluate the impact of exoskeleton human body posturizer (HBP) on the fall risk in the elderly. METHODS: 150 subjects (mean age 64.85; 79 M/71 F) with mild fall risk were randomized into two groups: 75 for group treated with human body posturizer (HBP group) and 75 for physical training without HBP group (exercise group). The effects of interventions were assessed by differences in tests related to balance and falls. Medically eligible patients were screened with Tinetti balance and Gait evaluation scale, short physical performance battery and numeric pain rating scale to determine fall risk in elderly people. RESULTS: In the HBP group there was a significant improvement in short physical performance battery, Tinetti scale and Pain Numeric rating scale with a significant reduction in fall risk (p < 0.05). In the exercise group we observed only minimal variations in the test scores. DISCUSSION: The results at the sixth and twelfth months show a twofold positive effect in the HBP group reducing fall risk and improving quality of life by reducing pain. CONCLUSION: The use of exoskeleton human body posturizer seems to be a new significant device for prevention of fall in elderly patients. Further research should be carried out to obtain more evidence on effects of robotic technology for fall prevention in the elderly.

The Marigliano-Cacciafesta polypathology scale (MCPS): a tool for predicting the risk of developing disability.

The purpose of the work was to verify whether our MCPS can be a tool for predicting the risk of developing disabilities. We considered 45 elderly subjects divided into three groups of 15 subjects each. Group 1 consisted of cases with a "moderate-severe" degree of polypathology, with no associated condition of disability evaluated by means of the activities of daily living (ADL). Group 2 contained cases with a "moderate" degree of polypathology (with no associated condition of ADL disability). The Group 3 was the control group with a "mild" degree of polypathology (with no disability associated with ADL). All subjects were re-evaluated after 6 and 12 months. Both Groups 1 and 2 of cases over time developed greater disabilities, compared to the control Group 3; in particular, the subjects with "moderate-severe" polypathology were more disabled after 12 months.

The Marigliano-Cacciafesta polypathological scale: a tool for assessing fragility.

The aim of our studies was to establish a standard method of assessment that allows an early identification of frailty in the elderly, i.e., to predict who are at risk of developing disabilities, in order to be able to intervene with preventive global and individualized measures. A new multidimensional scale called Marigliano-Cacciafesta polypathological scale (MCPS) was used on 180 elderly people, together with the Barthel index (BI), the global evaluation functional index (GEFI), the geriatric depression scale (GDS), the mini mental state examination (MMSE), the mini nutritional assessment (MNA), and the Tinetti test. A strongly significant statistical correlation was found between the MCPS and the nutritional state, mood level, motor functionality, level of disability and global functionality. As the fragile patients are at a risk to develop disabilities, we think that our scale can be a significant contribution to the multidimensional geriatric assessment (MGA), aimed at identifying and quantifying the parameter of fragility of each patient, an information which should be known, if we intend to introduce preventive measures.

Aging and Adherence to the Mediterranean Diet: Relationship with Cardiometabolic Disorders and Polypharmacy.

OBJECTIVES: To investigate the association between adherence to the Mediterranean Diet (Med-Diet), cardiometabolic disorders and polypharmacy. DESIGN: Cross-sectional study. SETTING: Geriatrics outpatient clinic, Policlinico Umberto I, Sapienza University of Rome. PARTICIPANTS: 508 patients (219 male, 289 female) aged 50 to 89 who were evaluated for cardiovascular and metabolic disorders. METHODS AND MEASUREMENTS: Patients underwent a comprehensive medical assessment including medical history and the use of medications. Adherence to Med-Diet was assessed using the validated Med-Diet 14-item questionnaire; for the analysis, patients were divided in high (≥8) and medium-low (<8) adherence. Polypharmacy was defined as taking ≥5 medications. RESULTS: 476 patients completed the study. Mean age was 70.4 years; 58% female. Median Med-Diet score was 8 (interquartile range, 6-9). Patients with medium-low adherence had higher body mass index (p=0.029) and higher prevalence of arterial hypertension (p<0.001), previous coronary (p=0.002) and cerebrovascular events (p=0.011), diabetes, (p<0.001) and dyslipidemia (p=0.001) compared to those at high adherence. Med-Diet score decreased with the number of cardiometabolic disorders (p<0.001). The prevalence of polypharmacy was 39%. Consumption of olive oil (p=0.005), vegetables, (p<0.001), wine (p=0.017), legumes (p=0.028), fish (p=0.046) and nuts (p=0.045) were all inversely associated with the overall number of medications. In a multivariable regression model, medium-low adherence to Med-Diet was independently associated to polypharmacy (O.R.:1.859; 95% CI 1.142 to 3.025; p=0.013), after adjusting for possible confounding factors. CONCLUSION: Med-Diet was inversely associated with cardiometabolic disorders and with polypharmacy, suggesting that improved Med-Diet adherence might potentially delay the onset of age-related health deterioration and reduce the need of multiple medications.

Diabetes and metabolic syndrome (MS).

The MS is associated with increased morbidity and mortality for cardiovascular disease (CVD). MS is represented not only by metabolic alteration such as hyperglycemia, and hyperlipemia but also by a chronic pro-inflammatory state. Another responsible in the formation and progression of CVD is the so-called endothelial dysfunction, which is linked to insulin resistance itself. The common denominator of the MS is insulin resistance. The most convincing evidence for the existence of MS comes from the cluster analysis which outlines four main factors: the "metabolic factor", the "pressure factor", the "lipid factor" and the "obesity factor". It is clear that the presence of the MS appears to identify a substantial additional cardiovascular risk on top of the individual risk factors. The studies available in the literature have pointed out the beneficial effects, in terms of cardiovascular mortality, of the treatment with inhibitors of the 3-hydroxy-3-methylglutaryl coenzyme A reductase (statins): this reduction of risk has been observed despite the fact that high triglyceride and low high-density lipoprotein (HDL)-cholesterol levels, but not hypercholesterolemia, are the main features of the dyslipidemia observed in patients with MS. Yet, despite a normal low-density lipoprotein (LDL)-cholesterol level, patients with MS are at high risk for future CVD. For this reason, their treatment with statins is mandatory.

Cognitive function by brain event-related potentials (ERP) in elderly with borderline isolated systolic hypertension (BISH).

Several studies have shown a relationship between BISH and cerebrovascular events, but no studies have investigated a relationship with cognitive function. The aim was to assess the cognitive function in the elderly with recent BISH. According to WHO Guidelines (1999), we selected 10 elderly normotensives, 10 elderly with recently diagnosed (<2 years) BISH, and 10 elderly with recently diagnosed (<2 years) isolated systolic hypertension (ISH). They were submitted to 24-hr ambulatory blood pressure (BP) monitoring (ABPM) and to cognitive assessment by mini mental state examination (MMSE) and the recording of brain ERP, of type N2 and P300. The elderly with BISH, compared to normotensives, showed N2 wave latency values significantly higher, but similar P300 potential latency values and MMSE scores. The elderly with ISH showed N2 and P300 latency significantly higher than the normotensives. The gradual increase of the ERP latency values of the BISH and ISH elderly, in comparison to the normotensives, seems to indicate a gradual alteration of the cognitive processes related to the increase of BP.

Sleep quality of centenarians: cognitive and survival implications.

Sleep is an active nervous process, which is structured in phases characterized by subsequent cycles of various psycho-physiological phenomena. It performs vital, yet mysterious functions and is in all likelihood involved in many processes, including cognitive processes. In old age the internal structure of sleep changes, but these physiological variations allow, in healthy subjects, a satisfactory quantity and quality of sleep. Until now there have been no literature reports of studies regarding sleep quality in extreme old age. Our work describes the investigation of the quality of sleep in a sample of 180 centenarians selected from the registered residents of Rome. We have studied sleep disorders, related pathologies and pharmacological treatments. The results of the study show good sleep quality for 57.4% of the sample group; 35.2% complain of medium intensity problems, significantly related to angina pectoris and to chronic obstructive bronchopneumopathy. Only 7.4% of the subjects showed severe problems, significantly related with cognitive deficiency and lower survival rate. The results of our study confirm, in centenarians as in the elderly, the existence of a positive correlation between sleep quality, survival and successful aging.

Autonomic modulation and QT interval dispersion in hypertensive subjects with anxiety.

Anxiety is associated with an increased risk of sudden death. QT dispersion is a marker of cardiac repolarization instability and is seen in conditions of high risk of sudden death. The purpose of this study was to evaluate autonomic nervous system control and QT dispersion in hypertensive subjects with anxiety symptoms. In a recent preliminary study, we observed that hypertensive individuals reporting high scores on a self-assessment anxiety scale had more marked left ventricular hypertrophy. In 105 hypertensive subjects divided into 3 groups according to severity of anxiety, we evaluated autonomic control by short-term power spectral analysis of RR and arterial pressure variability at rest (baseline) and during sympathetic stress (tilt test), left ventricular mass index, and heart rate-corrected QT (QTc) dispersion. At baseline, hypertensive subjects with higher anxiety symptom scores had significantly lower high-frequency RR values expressed in absolute terms (P<0.05) and in normalized units (P<0.05) than their counterparts without anxiety symptoms. Hypertensive subjects with anxiety also had a higher mean left ventricular mass index (P<0.001) and greater QTc dispersion (P<0.001). Both indexes and high frequency (P<0.05) correlated with severity of anxiety. These findings suggest that anxiety is associated with autonomic imbalance. This condition could favor an increase in left ventricular mass. Myocardial hypertrophy alone or combined with neuroautonomic imbalance may lead to QT dispersion.

Heart rate and blood pressure variabilities in salt-sensitive hypertension.

In salt-sensitive hypertension, a high sodium intake causes plasma catecholamines to rise and pulmonary baroreceptor plasticity to fall. In salt-sensitive and salt-resistant hypertensive subjects during low and high sodium intakes, we studied autonomic nervous system activity by power spectral analysis of heart rate and arterial pressure variabilities and baroreceptor sensitivity. In all subjects, high sodium intake significantly enhanced the low-frequency power of heart rate and arterial pressures at rest and after sympathetic stress. It also increased heart rate and arterial pressure variabilities. During high sodium intake, salt-sensitive hypertensive subjects had significantly higher low-frequency powers of systolic arterial pressure (7.5 mm Hg2, P < .05) and of heart rate at rest (59.2 +/- 2.4 normalized units [NU], P < .001) than salt-resistant subjects (6.6 +/- 0.3 mm Hg2, 55.0 +/- 3.2 NU) and normotensive control subjects (5.1 +/- 0.5 mm Hg2, 41.6 +/- 2.9 NU). In salt-sensitive subjects, low sodium intake significantly reduced low-frequency normalized units (P < .001) and the ratio of low- to high-power frequency (P < .001). High-sodium intake significantly increased baroreflex sensitivity in control subjects (from 10.0 +/- 0.7 to 17.5 +/- 0.7 ms/mm Hg, P < .001) and salt-resistant subjects (from 6.9 +/- 0.7 to 13.9 +/- 0.9, P < .05) but not in salt-sensitive subjects (7.4 +/- 0.3 to 7.9 +/- 0.4). In conclusion, a high sodium intake markedly enhances cardiac sympathetic activity in salt-sensitive and salt-resistant hypertension. In contrast, although reduced sodium intake lowers arterial pressure and sympathetic activity, it does so only in salt-sensitive subjects. Hence, in salt-resistant subjects, neither arterial pressure nor sympathetic activity depends on salt intake. During a high sodium intake in normotensive subjects and salt-resistant hypertensive subjects, increased sympathetic activity is probably compensated by enhanced baroreflex sensitivity.

The use of colony stimulating factors in elderly patients with cancer.

Hematological toxicity is the most common and the most frequent fatal complication of chemotherapy. It is observed with increased frequency with age, it is a significant independent predictor of the development of febrile neutropenia, and may contribute to a reluctance to administer chemotherapy in the elderly patient population. The authors analyze published data on effectiveness and results of the use of colony stimulating factors for preventing and treating elderly patients affected by tumors during chemotherapy.

The unexpected contribution of immunosenescence to the leveling off of cancer incidence and mortality in the oldest old.

In this paper the hypothesis that some features of immunosenescence might impact on the levelling off of cancer incidence and mortality in the oldest old will be considered. In fact, the term immunosenescence suggests that a progressive loss of immune system (IS) function occurs with aging. However, the age-related modifications of the IS can be more properly acknowledged as a 'remodeling' characterized by profound structural changes, which modify the functional properties of IS. We suggest that the expansion with age of natural killer cells (NK) and of T cells which progressively acquire phenotypes intermediate between T lymphocytes and NK cells, together with the age-related changes in the production of inflammatory/anti-inflammatory cytokines, such as INFgamma and IL-4, might create an environment unfavorable for neoplastic growth in the oldest old. In this perspective, studies on immunosenescence likely provide insights on mechanisms responsible for the individual capacity to escape from the life-threatening consequences of cancer outgrowth.

Pulsatile versus steady-state component of blood pressure in elderly females: an independent risk factor for cardiovascular disease?

OBJECTIVE: To evaluate whether the pulsatile component of blood pressure can be a risk factor independent of the steady component in elderly females. DESIGN: Fifty-two elderly hypertensive female patients were compared with 32 normotensive control subjects of the same age. According to the results of that first study, a cohort of 126 elderly females was studied over a 3-year period to evaluate whether the pulsatile and steady-state components of blood pressure correlated with the same parameters and could predict the occurrence of cardiovascular events. RESULTS: In the first study the hypertensive patients with elevated pulse pressure had significantly higher triglycerides level and lower urinary sodium excretion than the hypertensive patients with lower pulse pressure and than the control subjects of the same age. The incidence of cardiovascular events over a 3-year period was significantly higher in the elderly hypertensive females with increased pulse pressure. In the cohort of 126 females mean arterial pressure (MAP) and pulse pressure did not show the same degree of correlation with the biological parameters tested (plasma triglycerides: MAP r = 0.162, P < 0.05; pulse pressure r = 0.314, P < 0.0005; urinary sodium excretion: MAP r = -0.365, P < 0.0001; pulse pressure r = -0.257, P < 0.002). Furthermore, for the same MAP level, patients with cardiovascular accidents in a 3-year period had significantly higher pulse pressure values. Pulse pressure (and not MAP) was a strong predictor of cardiovascular accidents. CONCLUSIONS: In elderly hypertensive females the pulsatile and the steady-state components of blood pressure did not correlate with the same biological parameters. Furthermore, the pulsatile component, when explored by pulse pressure, seemed to be a strong independent cardiovascular risk factor.

Effects of carvedilol on heart rate and blood pressure variability in subjects with chronic heart failure.

In this study we observed that carvedilol administration to patients with heart failure improves hemodynamic function, baroreflex sensitivity, and heart rate variability. These findings contribute to improvement in survival in such patients.

Aging and red blood cell membrane: a study of centenarians.

Successful aging, characterized by little or no loss in physiological functions, should be the usual aging process in centenarians. It is known that well-preserved physiological functions depend on the proper functioning of cell systems. In this article we focus on cell membrane integrity and study the red blood cell membrane to evaluate the effect of physiological aging in centenarians. Fifteen healthy, self-sufficient centenarians, mean age 103 years, were examined by assessing hemocytometric values and some relevant characteristics of the erythrocyte membrane, i.e., the cholesterol/phospholipid molar ratio, the distribution of phospholipid classes and their fatty acid composition, the integral and skeletal protein profiles. The centenarians showed a significant decrease in the red blood cell count (p < 0.0002), hemoglobin (p < 0.0002), and hematocrit (p < 0.0005). The red blood cell membrane showed a significantly increased cholesterol/phospholipid molar ratio (p < 0.01), with a concomitant increase in polyunsaturated fatty acids in phosphatidylcholine (p < 0.001) and, to a lesser extent, in phosphatidylethanolamine. The electrophoretic pattern of membrane proteins was qualitatively normal compared to controls but the densitometric analysis showed a significant increase in the integral protein band 4.2 (p < 0.05) and in the skeletal protein actin (p < 0.001). Extreme longevity seems to be associated with a substantial integrity of the erythrocyte membrane. Moreover, the evident increase in polyunsaturated fatty acids and in actin are likely to improve the membrane fluidity and to strengthen the membrane structure.

Age-dependent influence on heart rate variability in salt-sensitive hypertensive subjects.

OBJECTIVE: The known association between systemic arterial hypertension in its initial stages and increased sympathetic nervous system drive prompted us to evaluate the influence of age on autonomic nervous system function in subjects with salt-sensitive arterial hypertension. DESIGN: In a randomized study, autonomic nervous system function was assessed by power spectral analysis of heart-rate variability calculated with an autoregressive algorithm in salt-sensitive hypertensives and controls at baseline and under sympathetic stress (passive head-up tilt). For 1 week before the study, all subjects kept to a diet supplying 120 mEq sodium. Sodium sensitivity was assessed by measuring and comparing arterial pressures after a 7-day controlled dietary sodium intake of 20 mEq per day after a 7-day period on 220 mEq sodium/day. SETTING: Geriatric division at the I Medical Clinic of the University of Rome "La Sapienza". PARTICIPANTS: Sixty-five patients with salt-sensitive hypertension (age range 19 to 89 years) and 64 age-matched normotensive controls, divided for data comparison into three age-groups: < 44 years; 44 to 64 years; and > or = 65 years. MEASUREMENTS: With an autoregressive algorithm in a power spectral analysis of heart rate variability, we detected four spectral frequency-domains: total power (0.0033 to 0.40 Hz), high-frequency power (0.16 to 0.40 Hz), low-frequency power (0.04 to 0.15 HZ) and very-low-frequency power (0.0033 to 0.04 Hz). To determine sodium sensitivity, for 1 week before the study all subjects kept to a diet supplying 120 mEq sodium. Sodium sensitivity was assessed by measuring and comparing arterial pressures after a 7-day controlled dietary intake of 20 mEq per day and after a 7-day period of 220 mEq sodium/day. RESULTS: Results were expressed as natural logarithms of power and normalized units. The hypertensive patients of all ages had significantly lower total power of heart rate variability than the normotensive controls (P < .05). At baseline, the youngest hypertensives had lower natural logarithms and low-frequency normalized units than controls (P < .001). After tilt, only their low-frequency normalized units exceeded those of controls (P < .001). The middle-aged hypertensive group had higher low-frequency normalized units than controls at baseline (P < .05) and after tilt (P < .001). At baseline and after tilt, the oldest hypertensives had lower low-frequency natural logarithms than controls (P < .05) and normalized units equal to those of controls. But the hypertensives of all ages were less able than controls (P < .001) to increase low-frequency power after head-up tilt. In the less than 44-year-old hypertensives, diastolic pressure correlated significantly with low-frequency power of heart rate variability, expressed in normalized units, at baseline (P < .05) and after head-tilt (P < .05). A significant inverse correlation was found between age and the natural logarithm of low-frequency power at baseline (r = -.682, P < .001) and after tilt (r = -.800; P < .001). Also, a significant inverse correlation was found to exist in normotensive subjects between the natural logarithm of low-frequency at baseline (r = -.595; P < .001) and after tilt (r = -.391; P < .001). The two regression line coefficients for age correlated significantly (P < .001) with the natural logarithm of low-power frequency after tilt. CONCLUSION: Whereas sodium chloride-sensitive hypertension appears to be associated with sympathetic hyperactivity in young and middle-aged subjects, in older people it is not. Sympathetic activity diminishes with age, declining faster in hypertensive subjects.

Insulin effects on the left ventricle in older hypertensive subjects.

BACKGROUND: To evaluate the effects of hyperinsulinemia on left ventricular (LV) structure and function in older hypertensive subjects METHODS: Thirty-seven hypertensive subjects (17 men/20 women) aged 50 to 80, were studied. LV mass were evaluated echocardiographically according to the Penn convention. A 75-g oral glucose tolerance test (OGTT) was performed after overnight fasting, and both blood glucose and insulin concentrations were assayed at 0, 30, 60, 90, 120, and 180 minutes. Comparison between groups was performed by analysis of variance. A P value of .05 was considered statistically significant. RESULTS: When the hypertensive patients were divided into two groups according to the median value of 2-hour post-loading plasma insulin, there was no difference in blood pressure levels between the groups. However, hyperinsulinemic hypertensive subjects had an increased LV mass (P < .05), mean wall thickness, and interventricular septum thickness (P < .05 for both parameters) and had better systolic function-ejection and shortening fractions (P < .0001 for both indices). CONCLUSIONS: Hyperinsulinemia may be associated with increased left ventricular mass and with a better systolic performance in older hypertensive subjects.

Platelet hyperactivity in hypertensive older patients is controlled by lowering blood pressure.

OBJECTIVE: Patients with hypertension tend to have a high prevalence of atherothrombotic accidents. Platelet hyperactivity is frequently associated with hypertension. Because the vascular disease associated with hypertension evolves over the years, we investigated platelet activity parameters in a population of older hypertensive patients with no other risk factors for cardiovascular disease. PARTICIPANTS: We studied 34 older, nonsmoking patients (mean age 74 +/- 5 years) with uncomplicated hypertension before and after the normalization of blood pressure (BP) was achieved with the angiotensin-converting enzyme inhibitor quinapril alone or in combination with the Ca2+ antagonist nifedipine. MEASUREMENTS: Platelet aggregation, P-selectin (CD62) expression on the platelet surface, serum levels of Interleukin-1beta (IL-1beta) and of Interleukin-6 (IL-6), as well as plasma levels of soluble P-selectin and Endothelin-1 (ET-1), were analyzed. RESULTS: All platelet hyperactivity parameters were reduced significantly with the normalization of BP at the end of antihypertensive drug treatment (systolic/diastolic: 186.2 +/- 2.7/103.4 +/- 1.1 mm Hg vs 135.0 +/- 1.3/85.9 +/- 1.9 mm Hg; P < .001). Those factors more strictly associated with endothelium injury, such as ET-1 and IL-6, did not show variations. A significant correlation (Spearman Rank test) was observed among all platelet function parameters and blood pressure values. CONCLUSIONS: This study demonstrated that even in a population of older hypertensive patients with no other risk factor for atherogenic disease, normalization of blood pressure induces a significant reduction of the parameters of enhanced platelet hyperactivity independent of the action exerted, at the platelet level, by the antihypertensive drugs.

Influence of aging and other cardiovascular risk factors on baroreflex sensitivity.

OBJECTIVES: To examine the influence of known cardiovascular risk factors (cholesterol, blood glucose levels, arterial pressures, heart rate, and aging) on baroreflex sensitivity. DESIGN: An observational epidemiological study. SETTING: Geriatric Division at the Policlinico Umberto Primo, University of Rome La Sapienza. PARTICIPANTS: Two hundred three subjects whose ages ranged from 9 to 94 years, apparently healthy and free of detectable clinical evidence of atherosclerosis. MEASUREMENTS: All subjects underwent determination of baroreflex sensitivity by phenylephrine infusion (BSphe), and by a noninvasive method derived from spectral analysis of R-R interval and arterial pressure variabilities (alpha index). RESULTS: The population, subdivided into tertiles for each variable studied, had lower BSphe values and lower alpha indexes as a function of age, plasma low-density lipoprotein (LDL) cholesterol, and systolic blood pressure. The alpha index was significantly lower in both groups with elevated LDL cholesterol levels than in those with lower levels (II and III vs I tertile, P <.001), whereas BSphe differed significantly only in the two groups who had extreme levels of LDL (I vs III tertile, P <.001). Multiple regression analysis identified a negative association of the alpha index with age (P <.001), heart rate (P <.01), area under the glucose-response curve (P <.001), and LDL cholesterol (P <.01), but of BSphe only with age (P <.001) and heart rate (P <.01). CONCLUSION: These findings indicate that some risk factors for coronary heart disease adversely influence baroreflex sensitivity.

Nimodipine in the treatment of old age dementias.

1. In a multicenter, placebo-controlled, double-blind clinical study in 178 elderly patients with cognitive decline, nimodipine, a calcium antagonist was found to be a therapeutically effective agent in the treatment of old age dementias. 2. Treatment with 90 mg of nimodipine administered orally in divided doses for 12 weeks was significantly superior to an inactive placebo on all outcome measures including the Wechsler Memory Scale, the Mini Mental State Examination, the Global Deterioration Scale, the Sandoz Clinical Assessment Geriatric Scale, the Plutchik Geriatric Rating Scale, the Severity of Illness and Global Improvement Scales of Clinical Global Impression, and the Hamilton Psychiatric Rating Scale for Depression. 3. Adverse effects with nimodipine were few and mild. The drug was equally well tolerated and equally effective in the two major dementias of old age, i.e., primary degenerative and multi-infarct. The number of abnormal laboratory test readings remained essentially unchanged from pre-treatment to post-treatment.

White-coat hypertension and cardiac organ damage in elderly subjects.

PURPOSE: The aim of this study was comparing the cardiac mass in elderly normotensive subjects and elderly white-coat hypertensive patients by examining in perspective, in consecutive patients, office blood pressure (BP), ambulatory BP, and echocardiographically determined left ventricular mass. PATIENTS AND METHODS: We studied 42 elderly patients attending a hypertension unit: of these, 22 (mean age 68.7 +/- 3.2 years) had persistent > 90 mm Hg office diastolic blood pressure (DBP), > 140 mm Hg systolic blood pressure (SBP) and < 142/90 mm Hg daytime ambulatory BP (white-coat positives); the remaining 20 (mean age 67.4 +/- 2.2 years) had < 90 mm Hg office DBP, < 140 mm Hg SBP and < 142/90 mm Hg daytime ambulatory BP (normotensives). White coat-patients (n = 22) were selected from a series of 75 consecutive newly diagnosed and never treated patients with mild hypertension (casual DBP constantly between 90 mm Hg and 105 mm Hg). RESULTS: Neither left ventricular mass index (89.9 +/- 23.1 vs 91.8 +/-25.4 P = NS and +/- 25.4 P = NS) and left ventricular mass/height, (115.4 +/- 17.1 vs 119.6 +/- 18.3 P = NS), nor relative wall thickness (0.31 +/- 0.44 vs 0.33 +/- 0.05 P = NS) were significantly higher in white-coat hypertensives as against normotensives. Neither did we find a relevant difference between left atrial diameters in the above considered groups (3.28 +/- 0.41 vs 3.32 +/- 0.37). In fact 81.8% of white-coat hypertensives had left ventricular normal geometry; whilst 13.6% only had concentric remodeling. Age and sex were associated with left ventricular mass index, left ventricular mass/height and relative wall thickness. Multiple regression analysis revealed that it is ambulatory, not office BP that carries independent information about relative wall thickness and left ventricular mass indices. CONCLUSIONS: Since elderly white-coat hypertensive subjects did not display a greater cardiac involvement than age-matched normotensives, they should be treated as such.
