Community-based studies have evaluated cross-sectional age relations of aortic stiffness measures, which are not often recapitulated in longitudinal studies. We examined baseline and longitudinal change in aortic stiffness in 5491 participants (mean age, 49.5±14.5 years; 54% women) who attended 2 sequential examinations (6.0±0.6 years apart) of the Framingham Heart Study. Cross-sectional relations of central hemodynamics (mean arterial pressure, central pulse pressure, carotid-femoral pulse wave velocity, and characteristic impedance) with age and risk factors were assessed at visits 1 and 2 (models 1 and 2). We used model 1 coefficients (M 1 ), visit 1 risk factor levels (R 1 ), and age at each visit (A 1 , A 2 ) to estimate values at visits 1 (M 1 R 1 A 1 ) and 2 (M 1 R 1 A 2 ). While using model 1 coefficients, we accounted for age and risk factor level (R 2 ) changes to predict values at visit 2 (M 1 R 2 A 2 ). Using model 2 coefficients (M 2 ) and visit 2 age and risk factor levels, we predicted visit 2 values (M 2 R 2 A 2 ). We calculated predicted change 3 ways: delta1=M 1 R 1 A 2 −M 1 R 1 A 1 , delta2=M 1 R 2 A 2 −M 1 R 1 A 1 , and delta3=M 2 R 2 A 2 −M 1 R 1 A 1 . Delta1 values were biased and correlated poorly with actual changes ( r =−0.02–0.14). For mean arterial pressure, delta1=1.9±0.8 mm Hg ( r =0.14), observed change=−3.3±10.3 mm Hg, and discrepancy=5.2±10.2 mm Hg ( P <0.0001). For characteristic impedance, delta1=7.2±14.7 dyne×sec/cm 5 ( r =0.07), observed change=20.5±68.2 dyne×sec/cm 5 , and discrepancy=−13.3±68.7 dyne×sec/cm 5 ( P <0.0001). Delta2 values were moderately correlated with change ( r =0.17–0.54) but remained biased whereas delta3 values were moderately correlated with change with no bias. Projected change in hemodynamic measures extrapolated from cross-sectional age relations may differ substantially from actual change, particularly for variables with nonlinear age relations.

Patients with hypertension (HT) and chronic obstructive pulmonary disease (COPD) have a high risk of cardiovascular complications. Up to now, there is no optimal strategy for combined antihypertensive therapy. Still, the data of 24-hour blood pressure monitoring (BPM) are important while choosing treatment tactics. The aim of the paper is to study the features of indicators in patients with arterial hypertension (AH) and COPD. Materials and methods. 130 patients with HT were included in the study. The main group (n=90) included comorbid patients with HT and COPD, their average age was 61.30±1.01; the comparison group (n=40) consisted of patients with HT, their average age was 59.10±1.53. All patients underwent 24-hour BPM. Results. Comorbid patients revealed an increase in the mean 24-hour and night systolic and mean arterial pressure values as well as a significant increase in the load index of systolic, diastolic and mean arterial pressure. Also, comorbid patients demonstrated higher blood pressure in contrast to the patients of the comparison group. They had increased systolic, diastolic and mean blood pressure variability and a quicker rate of morning blood pressure rise. According to 24-hour blood pressure dynamics, pathological types of the 24-hour blood pressure curve, a higher frequency of the night-peaker profile dominated in patients with COPD if compared to patients with HT. Conclusion. The obtained data indicated a high risk of cardiovascular complications in comorbid patients, early target organ damage and an unfavorable disease prognosis. It means that both further study of hypertension clinical course in such patients and personalization of antihypertensive therapy are relevant.

Пациенты с артериальной гипертензией (АГ) и хронической обструктивной болезнью легких (ХОБЛ) имеют высокий риск возникновения кардиоваскулярных осложнений. В настоящее время в лечении не определена наиболее оптимальная стратегия комбинированной антигипертензивной терапии. Для выбора тактики терапии важную роль играют показатели суточного мониторирования артериального давления (СМАД). Цель. Изучить особенности показателей СМАД у пациентов с АГ на фоне ХОБЛ. Материалы и методы. В исследование включено 130 пациентов с АГ. В основную группу (n=90) вошли пациенты с АГ и ХОБЛ (средний возраст – 61,30±1,01 года), в группу сравнения (n=40) – больные только АГ (средний возраст – 59,10±1,53 года). Всем пациентам проведено СМАД. Результаты. У пациентов с коморбидностью выявлены следующие особенности суточных показателей артериального давления: увеличение значений среднесуточных и средненочных показателей систолического и среднего артериального давления; существенное повышение индекса нагрузки систолическим, диастолическим и средним артериальным давлением. Также эти больные отличались от пациентов группы сравнения более высокими значениями пульсового давления, имели повышенную вариабельность систолического, диастолического и среднего артериального давления, у них наблюдалось увеличение скорости утреннего подъема артериального давления. Суточная динамика артериального давления у пациентов с ХОБЛ характеризовалась преобладанием патологических типов суточной кривой АД, более высокой частотой профиля night-peaker по сравнению с больными только АГ. Выводы. Выявленные особенности свидетельствуют о высоком риске сердечно-сосудистых осложнений у пациентов с коморбидностью, раннем поражении органов-мишеней и неблагоприятном прогнозе заболевания, что требует дальнейшего изучения особенностей клинического течения АГ у таких больных и индивидуализации антигипертензивной терапии. Ключевые слова: артериальная гипертензия, хроническая обструктивная болезнь легких, суточное мониторирование, артериальное давление.

Objective: Design an “in house” software for screening preeclampsia by maternal factors and mean arterial pressure at 11 – 13 gestational weeks in commune health centers. Methods: Based on the algorithms for calculating the risk of preeclampsia (PE) by maternal factors and mean artirial pressure at 11 - 13 gestational weeks in the study results of the authors, an “in house” software was deigned in Excel. The results of prediction preeclampsia by The Fetal Medicine Foundation (FMF)(version 2.3) were compared with the results by “in house” software in 1110 singleton pregnant women. Results: The “in house” software met the requirements for calculating the risks of PE and save data. FMF risk for gestational hypertension disorder in pregnancy by maternal factors, mean arterial pressure,uterine artery Doppler and PAPP-A has an area under the curve of 0.68 (95%CI: 0.59 – 0.78). The “in house” software risk for gestational hypertension in pregnancy by maternal factors, mean arterial pressure has an area under the curve of 0.643 (0.55 – 0.73) There was no statistically significant different between two programs (p:0.52). The risk cut-off 1:50 in the prediction of gestational hypertension of the “in house” software was used to identify the group of high risk with detetion rate (DR) 28.6% (95%CI: 14.9-42.2) comparing to 40.5% (95%CI:25.6-55.3) of FMF. Conclusion: The FMF version 2.3 is better but in the absence of Doppler ultrasound and PAPP-A test in the commune health cares, the “in house” software for screening PE is a good tool for councelling, following up and early intervention for PE.
