Synchronization index for quantifying nonlinear causal coupling between RR interval and systolic arterial pressure after myocardial infarction

2002

The analysis of nonlinear couplings among cardiovascular variability series can improve the knowledge of the cardioregulatory mechanism and help to understand how it can be affected by pathologies. In this study, the influences of acute myocardial infarction (AMI) on the causal relationships between the heart period and the arterial pressure were investigated by a nonlinear dynamic approach based on the corrected cross-conditional entropy. Whereas the global synchronization index did not differentiate the post-AMI patients from the young and old control groups, the causal indexes evidenced the impairment of the baroreflex control and showed an increase of the mechanical driving of the RR in…

A prospective randomized clinical trial compared the effect of various types of local anesthetics cartridges on hypertensive patients during dental e…

2015

Objectives: To evaluate hemodynamic changes of blood pressure and heart rate on hypertensive patients undergoing tooth extraction using various types of local anesthesia (LA). Study Design: A prospective randomized clinical trial was conducted on 45 hypertensive patients who were divided equally into 3 parallel groups according to LA received. Group 1: Lidociane 2% with epinephrine 1: 80,000. Group 2: Prilocaine 3% with Felypressin 0.03 IU/ml. Group 3: Mepivacaine 3% plain. Inclusion criteria: hypertensive patients, under medical management with blood pressure ≤ 159/99. Exclusion criteria: Blood pressure ≥160 /100 and patients receiving β blockers. Negative aspiration was mandatory before t…

Electrical Stimulation of Skeletal Muscles An Alternative to Aerobic Exercise Training in Patients With Chronic Heart Failure?

2006

The aim of this study was to investigate whether electrical stimulation of skeletal muscles could represent a rehabilitation alternative for patients with chronic heart failure (CHF). Thirty patients with CHF and NYHA class II-III were randomly assigned to a rehabilitation program using either electrical stimulation of skeletal muscles or bicycle training. Patients in the first group (n = 15) had 8 weeks of home-based low-frequency electrical stimulation (LFES) applied simultaneously to the quadriceps and calf muscles of both legs (1 h/day for 7 days/week); patients in the second group (n = 15) underwent 8 weeks of 40 minute aerobic exercise (3 times a week). After the 8-week period signifi…

Determinants of helicopter benefit for the transport of severe trauma patients

2013

Recently, Galvagno commented on the paper of Andruszkow and colleagues and summarized the studies using multivariate logistic regression to compare helicopter transport (HT) versus ground transport of trauma patients [1,2]. The authors did not mention our analysis of 1,958 trauma patients (26% transported by HT) specifically performed to investigate the influence of the mode of transport from the database of the French Intensive care Recorded in Severe Trauma study [3,4]. Compared with ground transport, HT patients were more intensively treated in the prehospital phase. The need for emergency surgical procedures and overall head surgical procedures until discharge from hospital were higher …

The causes of low adherence in patients with antihypertensive therapy

2016

Low adherence to antihypertensive therapy is a major cause of adverse cardiovascular outcomes by uncontrolled high blood pressure. If the most frequent causes of inappropriate taking of medicine are identified, possible improvements within the health care could be performed, promoting the safety and efficacy of antihypertensive therapy. The aim was to find the factors affecting patient's adherence during antihypertensive therapy. In the period from June to September 2014 a quantitative study was carried out including patients with diagnosed arterial hypertension who visited pharmacies in Riga to get the antihypertensive therapy. The study collected data of 152 patients with the mean antihyp…

Effect of comprehensive vasodilation vs usual care on mortality and heart failure rehospitalization in women with acute heart failure

2020

Abstract Background Guidelines recommend evaluating the risk/benefit ratio of novel therapies individually in women and men, as the pathophysiology and the response to treatment may differ between women and men. Among patients with acute heart failure (AHF), a strategy of intensive vasodilation, compared with usual care, overall did provide comparable outcomes. Purpose To evaluate the effect of a strategy that emphasized early intensive and sustained vasodilation in women with AHF. Methods In a randomized, open-label blinded-end-point trial patients hospitalized for AHF were enrolled in 10 hospitals in Switzerland, Bulgaria, Germany, Brazil, and Spain. Inclusion criteria were AHF expressed …

The efficacy of intra-articular PRP, ozone and ozone+PRP injections in patients with osteoarthritis

2018

Osteoarthritis (OA) is the most common form of arthritis and some joints are effected more than others. The prevalence of OA increases with age and it represents the major problem for functional impairment in older patients. Non-surgical treatment with oral drugs is not suitable for many patients suffering from gastric disorders, high blood pressure or different heart diseases. Intra-articular injections are a promising solution in these cases.
 This study was performed to compare the efficacy and safety of ozone injections, PRP (platelet rich plasma) injections and combined ozone plus PRP injections in patients with symptomatic knee OA. 
 120 patients were diagnosed of OA accordi…

Einfluss von Typ-II-Endoleaks auf die Größenänderung und Hämodynamik experimenteller Aortenaneurysmen nach endovaskulärer Therapie

2003

PURPOSE To evaluate the aneurysm volume and the intra-aneurysmatic pressure and maximal pressure pulse (dp/dtmax) in completely excluded aneurysms and cases with endoleaks. MATERIALS AND METHODS In 36 mongrel dogs, experimental autologous aneurysms were treated with stent-grafts. All aortic side branches were ligated in 18 cases (group I) but were preserved in group II (n = 18). Aneurysm volumes were calculated from CT scans before and after intervention, and from follow-up CT scans at 1 week, 6 weeks and 6 months. Finally, for hemodynamic measurements, manometer-tipped catheters were introduced into the excluded aneurysm sac (group I and II), selectively in endoleaks (group II), and intral…

Blood pressure reduction following treatment with positive airway pressure in sleep apnea: data from the European Sleep Apnea Database

2020

Abstract Introduction Positive airway pressure (PAP) treatment modifies blood pressure (BP) in patients with obstructive sleep apnea (OSA). We aimed to explore which factors that influence the BP response to PAP therapy in the European Sleep Apnea Database (ESADA). Methods A total of 2662 OSA patients with PAP therapy ≥90 days were included in the analysis (74% male, age 55±11 years, body mass index 32.3±6.1 kg/m2, 47% hypertensives, apnea-hypopnea index 40±24 events/h, treatment duration 1.0±1.1 years, PAP compliance 5.2±1.9 h/day). Anthropometric data, co-medications and office BP were assessed at baseline and follow-up visit. Results Systolic and diastolic BP were modestly reduced after …
