In this single-blind crossover study the antihypertensive efficacies of two dihydropyridine calcium antagonists, sustained-release isradipine and lacidipine, were compared using clinic and ambulatory blood-pressure measurements. After a 2-week placebo wash-out, 34 patients (19 men, 15 women, mean age 49 years) with mild to moderate hypertension (diastolic blood pressure range 95 – 110 mmHg) were treated with 5 mg sustained-release isradipine for 4 weeks and 4 mg lacidipine for 4 weeks in a random order. Medications were taken once daily at 08.00 h. Clinic and ambulatory blood pressures were recorded at the end of each placebo or treatment period. Two patients stopped isradipine and six lacidipine because of severe adverse effects. Clinic systolic and diastolic blood pressures decreased by an average of 17/14 mmHg with isradipine and 17/13 mmHg with lacidipine, compared with placebo ( P < 0.01 in both cases), without a change in heart rate. Mean ambulatory 24-h and daytime systolic and diastolic blood pressure were significantly reduced by sustained-release isradipine and lacidipine ( P < 0.05 and P < 0.01, respectively). At night systolic blood pressure fell compared with placebo ( P < 0.05 with both drugs) whereas the reduction in diastolic blood pressure was not statistically significant. Mean 24-h heart rate remained unchanged. Blood-pressure variability did not differ significantly between the two drugs or between either drug and the placebo. The antihypertensive effects of sustained-release isradipine and lacidipine were similar, but the tolerability of isradipine appears to be greater since it caused fewer withdrawals.

Objective. To provide reference data for ambulatory blood pressure monitoring (ABPM) and to determine the influence of age, sex, and race on these values. Methods. ABPM was performed on 300 healthy, normotensive boys and girls between the ages of 10 and 18 years, including 160 boys and 140 girls, of whom 149 were white and 151 were black. Mean systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) while awake and during sleep were calculated for black and white boys and girls aged 10 to 12 years, 13 to 15 years, and 16 to 18 years. Results. Boys compared with girls 10 to 12 years of age had higher mean (±SD) SBP (115 ± 9 vs 112 ± 9 mm Hg; P &lt; .01) and DBP (67 ± 7 vs 65 ± 5 mm Hg; P &lt; .01) while awake. Boys compared to girls 13 to 15 years of age had higher SBP while awake (116 ± 11 vs 112 ± 8 mm Hg; P &lt; .01). Boys compared with girls 16 to 18 years of age had higher SBP while awake (125 ± 12 vs 111 ± 9 mm Hg; P &lt; .01) and during sleep (116 ± 11 vs 106 ± 9 mm Hg). Comparisons within sex showed similar changes with age for boys and girls. Blacks compared with whites 13 to 15 years of age had higher SBP during sleep (109 ± 11 vs 105 ± 10 mm Hg; P &lt; .01), and blacks compared with whites 16 to 18 years of age had higher DBP during sleep (66 ± 7 vs 58 ± 6 mm Hg; P &lt; .01). Comparisons across age groups within race showed that blacks 16 to 18 years of age had higher SBP during sleep than blacks 10 to 12 years of age (109 ± 11 vs 104 ± 10 mm Hg), and higher DBP during sleep (66 ± 7 mm Hg; P &lt; .01) than blacks 10 to 12 years of age (61 ± 7 mm Hg; P &lt; .01) and 13 to 15 years of age (61 ± 8; P &lt; .01 mm Hg). The changes with age were not significant for white subjects. Conclusion. These results provide age-specific reference data for ABPM in youths. These values differ by sex (boys more than girls) and race (Blacks more than Whites).

The aim of the study was to determine the peculiarities of ABPM indices in middle-aged and elderly hypertensive patients depending on the daily BP profile. Material and methods. Indices of ambulatory blood pressure monitoring were identified in 57 middle-aged patients (45-59 years) (group I) and 43 elderly patients (60-74 years) (group II), who underwent two-week in-patient treatment. The control group consisted of 15 patients for every of the surveyed categories (group III - middle-aged and group IV – elderly respectively) matched with basic by age and gender. Results. We have shown that one of the factors that determines the change in hemodynamics in patients with essential hypertension is age, with the age patients experience the decrease in diastolic blood pressure with steadily increased systolic blood pressure, that should be considered in the prescription of antihypertensive treatment. With age, a gradual increase in systolic blood pressure is associated with the increased aortic stiffness, partially with the increase in collagen and the decrease in elastic fibrils and the formation of isolated systolic hypertension. Thus, it is proved that in the formation of isolated hypertension the growth of pulse blood pressure for more than 60 mm Hg is unfavorable in a development of cerebrovascular events. Pulse arterial blood pressure was stronger risk factor than systolic blood pressure and diastolic blood pressure or average arterial pressure in the elderly. Recently, taking into account age characteristics, all three indices were recognized as comparable predictors at the age of 50-59 years as the transitional period, and at the age of 60-79 years diastolic blood pressure adversely affecting the cardiovascular risk, increased pulse blood pressure prognostically above the level of systolic arterial pressure.

The efficacy and safety of sustained-release diltiazem, 200 – 300 mg once daily was compared with that of captopril, 12.5 – 25 mg twice-daily, in 100 elderly patients (65 – 85 years old) with mild to moderate essential hypertension (supine diastolic blood pressure 95 – 115 mmHg). All patients received placebo for 2 weeks, followed by an 8-week double-blind period, and were randomized to either diltiazem ( n = 50) or captopril ( n = 50). Their blood pressure was measured at trough level at week 4 immediately before dosing, i.e. 24 h post diltiazem dose or 12 h post captopril dose. Also at week 4, in non-responders, diltiazem was increased from 200 to 300 mg once daily and captopril from 12.5 to 25 mg twice daily to achieve a target supine diastolic blood pressure reduction of at least 10 mmHg or a diastolic blood pressure below 90 mmHg. Supine diastolic blood pressure, at week 8, was significantly ( P < 0.001) reduced from 102 ± 1 to 90 ± 1 mmHg with diltiazem and from 103 ± 1 to 89 ± 1 mmHg with captopril, bringing this parameter within normal limits for both groups. Supine systolic blood pressure was also significantly ( P < 0.001) reduced. Target blood pressure was achieved in 68% of patients taking diltiazem and in 70% taking captopril. Distribution of adverse events was comparable in both groups; no significant changes in laboratory or electrocardiographic parameters occurred. Two serious events were reported with captopril: one sudden death and one cerebrovascular stroke. Sustained-release diltiazem once a day is a convenient, well tolerated, first line treatment for hypertension in the elderly, for whom the possibility of using two dose levels allows a close regimen adjustment, 200 mg being recommended as a starting dose.

Handgrip Test

Cardiovascular autonomic neuropathy (CAN) is a common complication of diabetes mellitus. Cardiovascular reflex tests (CARTs) are the gold standard in the diagnosis of CAN, but the handgrip test is no longer recommended to be performed. Previously, the inverse association between the presence of hypertension and handgrip test abnormality was demonstrated and hypertension as major cause for excessive diastolic blood pressure rise during handgrip testing in diabetic individuals proposed. The aim of the present study is to describe more precisely the association between handgrip test and hypertension by performing ambulatory blood pressure monitoring (ABPM) among diabetic patients. A more comprehensive evaluation of the relationship between cardiovascular autonomic function, hypertension and the handgrip test was targeted using heart rate variability (HRV) analysis. Our study involved 163 patients with diabetes. Cardiovascular autonomic neuropathy was assessed by the CARTs and sustained handgrip test was performed. All patients underwent ABPM and HRV analysis well. CAN was diagnosed in 69 patients. Significant associations were found between the diastolic blood pressure increase in response to handgrip exercise and the 24-h (rho = 0.245, p = 0.003), daytime (rho = 0.230, p = 0.005) and night-time (rho = 0.230, p = 0.006) mean systolic and 24-h diastolic (rho = 0.176, p = 0.034) blood pressure values, systolic blood pressure load (rho = 0.252, p = 0.003) and systolic (rho = 0.236, p = 0.005) and diastolic (rho = 0.165, p = 0.047) hyperbaric impacts. Higher values of ambulatory blood pressure monitoring parameters are associated with greater increases in diastolic blood pressure during isometric handgrip exercise. Diastolic blood pressure elevations during the handgrip test are also correlated, in order to diminished heart rate variability parameters attributable to parasympathetic dysfunction highlighting the pivotal role of sympathetic overactivity in evolving handgrip test results. Our study provides further evidence on the inverse association between handgrip test abnormality and hypertension in diabetic patients.

Abstract BACKGROUND: Corticosteroids are still a cornerstone in multiple myeloma (MM) therapy, both as a single agent and as a part of many protocols, including VAD regimen (vincristine, adriblastine, dexamethasone). Corticosteroids are known to be involved in blood pressure (BP) regulation and to affect this parameter. The impact of dexamethasone (Dex) administration on BP in MM patients during VAD protocol treatment is poorly documented. AIM: The purpose of the study was to evaluate the blood pressure changes during Dex administration in patients treated with VAD protocol due to MM. METHODS: Thirteen patients with MM (7 men and 6 women; mean age 62,45 ± 8,14) were assessed. Primary hypertensive patients (7 persons) were not excluded. They were administered Dex in standard dose of 40 mg (day 1–4, 9–12, 17–21) according to VAD protocol. Blood pressure was assessed by the use of commercially available instruments of Ambulatory Blood Pressure Monitoring (ABPM). The BP recordings lasted 48 hours, were started on the day before the first day of VAD and were obtained every 10 minutes during mornings, every 15 minutes during the rest of days and every 20 minutes during nights. Average of systolic and diastolic blood pressure (SBP/DBP) were estimated for the 2-hour time before Dex and for the 14-hour time in the 2-hour periods after Dex. Minimal and maximal range of SBP/DBP increase and the mean amount of SBP/DBP increase were also determined. RESULTS: 48-hour BP recordings revealed a significant increase in systolic and diastolic blood pressure after Dex administration in all patients. SBP and DBP began to increase after 3 hours after Dex, then rose continually and reached the peak in the period from 6 to 10 hour after Dex. In comparison to 2-hour period before Dex, in which SBP/DBP amounted 139,63/82,92 ± 23,47/9,38 mmHg, the mean SBP/DBP increase rate was: in the 2–4 hour period after Dex - 146,68/88,15 ± 24,38/10,51 mmHg (p&lt;0,05), in the 6–8 – 148,07/92,66 ± 14,07/9,04 mmHg (ns), in the 8–10 – 147,8/87,99 ± 14,07/9,04 mmHg (p&lt;0,01), in the 10–12 – 143,44/86,12 ± 17,22/9,77 mmHg (p&lt;0,05) and in the 12–14 – 144,47/88,59 ± 17,04/12,54 mmHg (p&lt;0,01). The minimal range of SBP/DBP increase was 10,50/−2,00 mmHg, maximal range of SBP/DBP increase was 35,43/40,00 mmHg and the mean amount of SBP/DBP increase was 20,06/11,6 ± 8,36/14,23 mmHg. CONCLUSION: Our preliminary study revealed that Dex administration causes an increase in BP in all patients. The mean increase in BP amounted 20,06/11,6 ± 8,36/14,23 mmHg and was similar in all patients, regardless their initial value of BP. So our study demonstrates the need of individualized hypertension treatment with strict control of BP in hypertensive patients when corticosteroid therapy is indicated.

Objective.The possible effect of blood pressure measurements per se on heart rate variability (HRV) was studied in the setting of concomitant ambulatory blood pressure monitoring (ABPM) and Holter ECG monitoring (HM).Methods.In 25 hypertensive patients (14 women and 11 men, mean age: 58.1 years), 24-hour combined ABPM and HM were performed. For every blood pressure measurement, 2-minute ECG segments (before, during, and after measurement) were analyzed to obtain time domain parameters of HRV: SDNN and rMSSD. Mean of normal RR intervals (MNN), SDNN/MNN, and rMSSD/MNN were calculated, too. Parameter variations related to blood pressure measurements were analyzed using one-way ANOVA with multiple comparisons.Results.2281 measurements (1518 during the day and 763 during the night) were included in the analysis. Both SDNN and SDNN/MNN had a constant (the same for 24-hour, daytime, and nighttime values) and significant change related to blood pressure measurements: an increase during measurements and a decrease after them (p<0.01for any variation).Conclusion.In the setting of combined ABPM and HM, the blood pressure measurement itself produces an increase in short-term heart rate variability. Clarifying the physiological basis and the possible clinical value of this phenomenon needs further studies.
