Home blood pressure readings by self-monitoring (14 readings in 7 days) have been compared to readings taken in the clinic in 937 participants of the Tecumseh Blood Pressure Study. In the absence of firm criteria "hypertension at home" was defined as having home readings in the upper decile of the whole population. If a clinic reading exceeded 140 and/or 90 mmHg a subject was categorized as having clinic "hypertension". Two hypertensive groups emerged; one with both clinic and home hypertension ("sustained" N = 47) and one with high clinic but normal home blood pressure ("white coat" N = 50). Groups with "white coat" and "sustained" hypertension were very similar. Both groups were overweight, had faster heart rates, elevated cholesterol, insulin, triglyceride and decreased HDL levels. Blood pressure readings at previous exams (age 5, 8, 21 and 22) were elevated in both the "sustained" and white coat hypertension group compared to the normotensive controls. Subjects with white coat hypertension were not hyperresponders to the stress of mental arrythmetrics or to isometric exercise. The white coat hypertensives did not show abnormal anger, excessive submissiveness, or anxiety. The pathophysiology of the reproducible elevation of the clinic blood pressure in the white coat hypertensives remains unclear. Because of a higher risk of coronary heart disease and a risk for late development of sustained hypertension, subjects with white coat hypertension should be counselled on nonpharmacologic methods to control the blood pressure elevation and to ameliorate coronary risk factors.

During a survey of young subjects not receiving treatment for hypertension in Tecumseh, Michigan, clinic and self-monitored blood pressures taken at home (14 readings in 7 days) were obtained in 737 subjects (387 men, 350 women, average age 31.5 years). Hypertension in the clinic was diagnosed if the clinic blood pressure exceeded 140 mm Hg systolic or 90 mm Hg diastolic. In the absence of firm criteria for what constitutes hypertension at home, subjects whose average home blood pressure was in the upper decile of the whole population were considered to have hypertension at home. By these criteria, 7.1% of the whole population had "white coat" hypertension (i.e., high clinic but not elevated home readings). The prevalence of "sustained" hypertension (i.e., high readings in the clinic and at home) was 5.1%. Subjects with white coat and sustained borderline hypertension in Tecumseh were very similar. Both groups showed, at previous examinations (at ages 5, 8, 21, and 23 years), significantly higher blood pressure readings than the normotensive subjects. As young adults (average age 33.3 years), the parents of both hypertensive groups had significantly higher blood pressure readings than the parents of normotensive subjects. Both hypertensive groups had faster heart rates, higher systemic vascular resistance, and higher minimal forearm vascular resistance. Both hypertensive groups were more overweight, had higher plasma triglycerides, insulin, and insulin/glucose ratios than normotensive subjects. The white coat hypertensive group also had lower values of high density lipoprotein than the normotensive group. White coat hypertension is a frequent condition.(ABSTRACT TRUNCATED AT 250 WORDS)

The fatty acid pattern of serum triglycerides and FFA in normal untrained subjects, normotensive athletes, patients with labile and stable essential hypertension as well as in hypertensives with overweight and mild hypertriglyceridemia has been evaluated by gas liquid chromatography. The most striking differences revealed the linoleic acid in triglycerides being increased in athletes and in patients with labile hypertension in comparison with normotensive untrained controls and patients with stable hypertension. On the basis of these data an enhanced need of polyunsaturated fatty acids corresponding to probands with high physical activity has been assumed in patients with an early stage of essential hypertension. The differences of arachidonic acid were not so distinct. The results can be relevant with regard to the pathogenetic role of prostaglandin precursors in the development and course of essential hypertension and atherosclerosis.

"White-coat" hypertension, i.e. high readings in the clinic but normal readings at home, has been demonstrated in 21-58% of hypertensive subjects without end-organ injury. The condition can be diagnosed by means of home blood pressure monitoring, which should therefore be used as a supplement to monitoring by the physician. Owing to the low blood pressure readings at home, these patients should not be treated with drugs. In the event of anti-hypertensive treatment, home blood pressure monitoring is useful in helping to decide the minimum required dose, thus reducing risk of side effects, and in monitoring the response to therapy. White coat hypertension is associated with overweight, lipid abnormalities and high fasting insulin. Owing to the high risk of developing sustained hypertension, the patients' blood pressure must be measured regularly both at the clinic and at home.

The purpose of the present study was to determine the relationship between body mass index (BMI) and parameters derived from 24-hour ambulatory blood pressure monitoring including mean 24-hour daytime and nighttime systolic and diastolic blood pressures, 24-hour daytime and nighttime pulse pressure, mean 24-hour daytime and nighttime heart rate, dipping and nondipping status. 3216 outpatient subjects who visited our hypertension center and were never treated with antihypertensive medication underwent 24-hour blood pressure monitoring. BMI was significantly correlated with clinic systolic and diastolic blood pressures. Significant correlations were also found between BMI and mean 24-hour daytime and nighttime systolic blood pressure, 24-hour daytime and nighttime pulse pressure, and mean 24-hour daytime and nighttime heart rate. In multivariate regression analysis, clinic systolic, diastolic blood pressure, mean 24-hour systolic blood pressure, 24-hour pulse pressure, and high-density lipoprotein were independently correlated with BMI. The incidence of white coat hypertension was higher in overweight and obese patients than in normal weight subjects. Confirmed ambulatory blood pressure hypertension was also found to be higher in overweight and obese individuals compared with normal weight subjects. Our data also highlight the higher incidence of nondipping status in obesity. These findings suggest that obese patients had increased ambulatory blood pressure parameters and altered circadian blood pressure rhythm with increased prevalence of nondipping status.

Since the prevalence and clinical characteristics of young-onset hypertension are still to be elucidated, we performed targeted-screening at an annual university health check-up for two consecutive years. Out of 16,464 subjects in 2003 and 17,032 in 2004 that were aged less than 30 years, 22 and 26 students (all males) exhibited high blood pressure (BP), respectively, on three occasions during casual BP measurements at the Tohoku University Health Center (systolic and diastolic BP of 140 and/or 90 mmHg or greater, respectively). These students were asked to measure their BP at home, and 9 subjects in total were diagnosed as having essential hypertension (EH). The remaining students were diagnosed as having white coat hypertension (WCH). In 8 out of 9 EH students, their father and/or mother had also been treated with antihypertensive medication. Adjustment by attendance ratio for each BP measurement suggested that the incidence of EH was around 0.1% and that of hypertension (EH and WCH) was around 0.5% in university students aged less than 25 years, since most of the subjects and hypertensive students were between 18 and 24 years old. Body mass index of the EH, which was more than 25 kg/m2 (overweight), was significantly higher than that with WCH. In conclusion, the combination of repeated casual BP measurements and home BP effectively identified young-onset EH. The clinical parameters indicated that male gender, genetic background, and excessive weight were risk factors for young-onset hypertension.

The aim of the present study was to determine if there is any association between white coat hypertension (WCH) and body mass index. The study was performed in two phases. In the first phase, we studied consecutive underweight patients, while in the second phase, age-matched consecutive normal weight, overweight, and obese cases were studied. Although we detected 61 cases in the underweight group with a mean age of 24.1 years, we could only detect 12 age-matched cases in the obesity group, and thus the obesity group was not used for comparison. When we looked at the prevalences of sustained normotension (NT), WCH, and HT in the groups, there were gradual and significant increases in the prevalences of WCH in addition to the gradual and significant decreases in the sustained NT from the underweight towards the normal weight and overweight groups. Eventually, only 31.5% of the overweight group had sustained NT, even though the mean age of the cases was very young. Due to the gradually increased prevalence of WCH from the underweight towards the normal weight and overweight groups, parallel to the already known increasing prevalences of HT, type 2 diabetes mellitus, hyperbetalipoproteinemia, dyslipidemia, and coronary heart disease and the very low prevalence of sustained NT among the overweight cases even in the early decades here, WCH should preferentially be accepted as an alarming sign of excess weight and many associated disorders in the future, rather than just being considered a predisposing factor of HT or atherosclerosis alone.

Although white coat hypertension (WCH) is believed to have an effect on health, there is no term defining WCH in metabolic syndrome. Consecutive patients 20 years old or older who underwent a check-up were included. The study included 1068 cases. The prevalences of hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, impaired glucose tolerance (IGT), and WCH were similar to excess weight in that they increased significantly until the seventh decade of life and decreased thereafter significantly (P < 0.05 in most steps). On the other hand, the prevalences of hypertension (HT), diabetes mellitus (DM), and coronary heart disease (CHD) always increased significantly with age without any decrease (P < 0.05 in most steps), indicating their irreversibility in contrast to the reversibility of excess weight, hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, IGT, and WCH. Metabolic syndrome is a reversible progression step between health and irreversible final diseases terminating with increased mortality and disabilities. Thus, the definition of metabolic syndrome should include reversible metabolic risk factors such as excess weight (overweight and obesity), hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, IGT, and WCH, instead of irrevesible diseases such as DM, HT, CHD, and stroke that have already developed and require drug therapy. After development of one of the final metabolic diseases, the term metabolic syndrome probably loses most of its significance, since from that point on, nonpharmaceutical approaches such as lifestyle changes, diet, and exercise will provide little benefit to prevent development of the others, most likely due to the cumulative effects of the risk factors on body systems over a long period of time.

White coat hypertension (WCH) is most likely a disorder associated with metabolic syndrome. The study was performed at the Internal Medicine Polyclinic of Dumlupinar University on routine check-up patients. WCH cases who were overweight or obese and desiring weight loss were divided into two subgroups according to whether they preferred to achieve weight loss by medication or diet therapy. The study included 324 cases (204 females) with WCH, 45 of whom were in normal weight range. Therefore, 86.1% (279) of cases with WCH were either overweight or obese, and 41.3% (134) of all WCH cases had dyslipidemia. Twenty-five cases (14.7%) stopped metformin therapy due to excessive anorexia. At the end of a 6-month period, there were highly significant differences between the two groups with respect to the prevalences of resolved WCH, hyperbetalipoproteinemia, hypertriglyceridemia, dyslipidemia, overweight and obesity, and decreased fasting plasma glucose below 110 mg/dL (P < 0.001 for all). Due to gradually increased prevalences of impaired glucose tolerance, type 2 diabetes mellitus, dyslipidemia, excess body weight, and obesity-like disorders from sustained normotension towards WCH and hypertension (HT) cases, and very high prevalences of excess weight and dyslipidemia in the WCH group, WCH may be an associated disorder of metabolic syndrome rather than just being a predisposing factor of atherosclerosis or HT alone. Thus, the management of WCH should not focus solely on the regulation of blood pressure with antihypertensive medications, but rather on the prevention of future excess weight and various associated disorders, and metformin alone is an effective therapeutic option, most likely due to its powerful inhibitory effect on appetite.

The character of changing of functional and vegetative characteristics in different clinical variants of arterial hypertension thus far remains obscure. The aim of this work was to study patients with stable arterial hypertension (SAH), its masked form (MH), and white coat hypertension (WCH). We examined 125 patients who were divided into these 3 groups based on results of 24 hr AP monitoring by cardiac rhythm measurement and echocardiography. The study revealed different risk factors of each of the three forms of AH. The main risk factors of WCH are age and disturbed rhythm variability, those of MH are overweigh, obesity, and myocardial dysfunction, while SAH is associated with the advanced age, overweight, obesity, the history of concomitant cardiovascular diseases, and disordered daily profile of AP. It is concluded that different clinical variants of AH result from the changes in the functioning of cardiovascular and vegetative nervous systems associated with different risk factors.
