[Effect of the presence of a drug in the list of supplementary drug provision on compliance to its administration by outpatients with arterial hypertension].

Aim of the study was to investigate relationship between the presence of a drug in the list of supplementary drug provision (SDP) and compliance to its consumption by outpatients with arterial hypertension as well as determination of the place of SDP in a row of other factors affecting compliance to treatment. Methods. Patients (men and women) older than 18 years with initial level of office systolic arterial pressure (AP) 140-179 mm Hg and diastolic AP up to 100 mm Hg who visited regional internist. The study was conducted at the base of 82 Moscow polyclinics with participation of 185 physicians and 5474 patients. In all patients besides general clinical examination with office AP measurement calculation of body mass index and assessment of risk factors and concomitant therapy were carried out. All patients assessed themselves their self feeling with the use of visual-analog scale (VAS). Compliance of patients to antihypertensive therapy was evaluated with the help of the Moriski - Green test. Fact of continuous use of antihypertensive drugs received by patients within framework of the SDP system was necessarily obligatory. For final analysis 4816 ambulatory cards were selected. Results. Portion of patients with low compliance to therapy was greatly than that of patients with high compliance to therapy (61.1 vs. 38.9%, respectively, p=0.00001). Inclusion into analysis of additional factor (presence of CHD) reduced contribution of SDP to compliance to 25%, but it remained as before significant (p<0.0007). However addition to these factors of other parameters such as presence of diabetes mellitus or tonometer at home completely leveled effect of SDP on compliance to therapy (p<0.12). Conclusion. Presence of drugs in the SDP list significantly elevates compliance to therapy. However SDP does not appear the only independent predictor of high compliance. If SDP is considered together with other determining factors (presence of concomitant IHD and diabete, readiness to spend money for tonometer) its role as independent factor of high compliance is diminished and loses significance.

[Assessment of major artery stiffness: new perspectives of noninvasive diagnosis of coronary atherosclerosis].

AIM: Arterial stiffness is a predictor of atherosclerosis. This study was conducted to develop a method of coronary atherosclerosis severity assessment by means of brachial-ankle pulse wave velocity (baPWV). MATERIAL AND METHODS: We measured baPWV in 119 males (age 51.67 +/- 7.25) who received coronary angiographic examination (CAG). The baPWV was measured by Vasera VS-1000 (Fukuda Denshi). RESULTS: The patients were divided into two groups by severity of stenosis (group 1--less than 50% stenosis, group 2 > 50%). The baPWV value was significantly greater in group 2 (n = 98, baPWV 13.15 +/- 2.14 m/s, p = 0.004) than that in group 1 (n = 21, baPWV 12.13 +/- 1.17 m/s). ROC-curve demonstrated that the best cut-off point of the baPWV for predicting occlusive atherosclerosis was 12.2 m/s. The area under ROC-curve was 0.66 (p = 0.034). An univariate binary logistic regression model demonstrated that only baPWV had a significant odds ratio for coronary stenosis > 50%: 2.68 (95% CI = 1.01-7.15), p = 0.043. Other risk factors were not significantly associated with severity of stenosis. CONCLUSION: The baPWV significantly reflects the severity of stenosis in middle-aged males opening new perspectives of noninvasive detection of coronary artery atherosclerosis in middle-aged males.

[Clinical and economical effectiveness of outpatient diagnostic coronary angiography].

Introduction into clinical practice of transradial coronary angiography (CA) made it possible to conduct the procedure in outpatients and thus increase number of CA and diminish its cost. Aim of the study was to assess possibility, safety and economical efficacy of outpatient CA. Between April 2004 and August 2007 CA was carried out in 133 outpatients without overt heart failure, unstable angina, complex disturbances of cardiac rhythm or conduction. Comparison group comprised 187 patients subjected to CA within framework of short term hospitalization program. There were no complications associated with the use of either transradial or transfemoral approach. Total average cost of outpatient CA was 19% less than that of inhospital CA. Thus outpatient CA with transradial approach appears to be safe and effective procedure with low risk of complications in patients with stable ischemic heart disease.
