Introduction. Among the priorities of the strategic development of the health care system there is the telemedicine technologies implementation. Material and methods. The project was developed in the Penza State University. For the economic justification of the remote BP monitoring, the project technological scheme has been prepared, the market capacity has been assessed and competition has been analyzed, the business model and financial model of the project have been developed, and risks have been evaluated. Results. The project is deployed at the base and with the participation of the budget medical institution. The patient is provided with a tonometer with built-in GSM or blutooth module. After the patient’s BP has been measured, the data in an encrypted format is transmitted to the remote monitoring center and stored in the cloud base. For each patient, the doctor sets target and individual thresholds for blood pressure. Intermediate monitoring of BP is carried out by paramedical personnel who, in case of deviations from reference values, notify the attending physician. The patient receives feedback in the form of SMS-messages to his mobile phone: time for BP measuring, taking drugs and recommendations for the therapy correction. Payment is carried out according to the approved Mandatory Medical Insurance Fund tariff. Conclusion. The introduction of remote blood pressure monitoring will reduce the cost of providing medical care by reducing the number of hypertension complications, open up prospects for research and development of medical professionals. Fundamentally new conditions will arise for the study of chronopharmacology of antihypertensive drugs in patients with hypertension.
The aim of the study was to evaluate the diagnostic significance of ST-segment re-elevation episodes registered with telemetric ECG monitoring in patients with ST-segment elevation myocardial infarction (STEMI) treated with thrombolytic therapy (TLT). The study included 117 patients with STEMI following effective TLT. The elective coronary angiography followed by percutaneous coronary interventions was performed in the interval from 3 to 24 hours after a successful systemic TLT. Before and after cardiac catheterization, the telemetric ECG monitoring was performed using AstroCard Telemetry system (Meditec, Russia). During the study, two groups of patients were formed. Group 1 included 85 patients (72.6%) without new ST-segment deviations on telemetry. 77 patients (90.6%) had no recurrent coronary artery thrombosis at angiography. Eight patients (9.4%) from group 1 were diagnosed with thrombosis of the infarct-related coronary artery. Group 2 included 32 patients (27.4%) who underwent TLT and then had ST-segment re-elevation episodes of 1 mV or more in the infarct-related leads, lasting for at least 1 minute. In group 2, in 27 of 32 patients (84.4%), thrombosis of the infarct-related coronary artery was confirmed (p<0.01 compared with group 1). In 71.9% cases, the recurrent ischemic episodes were asymptomatic (‘painless myocardial ischemia’) (p<0.01). Thus, in patients with STEMI and successful TLT, re-elevation of ST-segment during remote ECG monitoring is strongly related to angiographically documented coronary artery thrombotic reocclusion. The absence of chest pain during recurrent myocardial ischemia requires continuous ECG telemetry to select patients for the rescue percutaneous coronary interventions at an earlier stage.
Цель. Оценка динамики ряда показателей, характеризующих ритмическую деятельность сердца, в зависимости от эффективности фармако-инвазивной реваскуляризации у больных STEMI. Материал и методы. Включено 56 пациентов со STEMI, которым проведена эффективная по ЭКГ-критериям ТЛТ, через 3-24 ч после которой выполнена коронароангиография со стентированием. До и после проведения ЧКВ прове-дена телеметрическая регистрация ЭКГ с использованием комплекса "Aстро-кард ® -Телеметрия" (ЗАО "Медитек", Россия). Выполнен автоматизирован-ный анализ спектральных характеристик ВСР, ППЖ, ТСР. Результаты. При развитии ретромбоза коронарной артерии происходит снижение общей мощности спектра (TotP) (р=0,001) и увеличение индекса вагосимпатического баланса (L/H) (р=0,005), что указывает на повышение автономной регуляции и децентрализацию управления сердечной дея-тельностью. Обратная динамика регистрируется после успешного ЧКВ, что может быть связано с восстановлением баланса парасимпатической и симпатической активности при эффективной реваскуляризации. Выяв-лена тенденция к увеличению продолжительности показателя QRSf в группе больных с ретромбозом, также установлено, что при позднем проведении ЧКВ возрастает показатель RMS (р=0,04), что указывает на высокий риск развития электрической нестабильности миокарда у дан-ных пациентов. Заключение. Маркерами развивающегося ретромбоза инфаркт-связанной коронарной артерии у пациентов со STEMI являются: повышение низкочастот-ных показателей ВСР (VLfp и LfP), снижение общей мощности спектра ВСР, увеличение индекса L/Н и увеличение продолжительности QRSf. При позднем проведении ЧКВ регистрируются высокие показатели RMS, что указывает на электрическую нестабильность миокарда у данной категории пациентов. Телеметрический мониторинг ЭКГ у больных STEMI существенно расширяет возможности динамической оценки состояния коронарного кровотока и элек-трической нестабильности миокарда. Aim. To assess the dynamics of parameters representing rhythmical activity of the heart related to the efficacy of pharmaco-invasive revascularization in STEMI patients. Material and methods. Totally 56 STEMI patients included that had undergone effective thrombolysis by ECG criteria of reperfusion, after that in 3-24 hours the coronary arteriography and stenting was done. Before and after PCI the telemetric ECG registration was done via "Astrocard ® -Telemetry" (Meditek Ltd., Russia). The automatic analysis of spectral parameters was done for HRV, LVP, RT. SPECTRAL HEART RATE VARIABILITY PARAMETERS, DELAYED VENTRICULAR POTENTIALS AND RATE TURBULENCE AS MARKERS OF CORONARY PERFUSION IN STEMIResults. In coronary artery re-thrombosis development there is a decrease of spectrum power (TotP) (p=0,001) and increase of vagosympathic balance (L/H) (p=0,005) that points on the increase of autonomic regulation and decentralization of heart activity management. Backward dynamics is registered after successful PCI that might be related with the balance restoration between sympathetic and parasympathetic systems in effective revascularizat...
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
