Left ventricular ejection fraction (EF) is used to assess patients with heart failure (HF); however, frequent measurements are not cost-effective. Impedance cardiography (ICG) is a low-cost, noninvasive test that measures systolic time intervals and may be a method for detecting impaired vs intact EF. This study evaluated the relationship between EF by echocardiography or gated nuclear ventriculography and systolic time ratio (STR) by ICG in outpatients with chronic HF. A retrospective chart review identified 52 patients with EF and STR measured within 2 weeks. There was an inverse correlation between STR and EF (r=-0.54; P<.001). The area under the receiver operating characteristic curve for STR to identify reduced EF was 0.86. An EF < or =50% and STR > or =0.50 demonstrated 93% sensitivity and 85% specificity. STR was able to distinguish intact (>50%) from impaired EF (< or =50%). STR by ICG has the potential to be a reliable method to monitor ventricular function in chronic HF.
Cannabidiol (CBD) is a non-psychotropic cannabinoid obtained from hemp ( L.) used for pain management in companion animals including horses. The present study aimed to evaluate the efficacy of cannabidiolic acid (CBDA) and cannabigerol/cannabidiol oil (CBG/CBD) oral administration in alleviating pain in adult horses affected by chronic osteoarthritis (OA).
Objective: To examine the effectiveness of telemedicine on blood pressure control and compliance.
Design: Systematic review and meta-analysis.
Data Sources: A search of PubMed, Web of Science, Embase and Cochrane Library for studies of randomised controlled trials (RCTs) of telemedicine on blood pressure control in poststroke survivors from the time of their construction until November 2023.
Background: Hypertension is a risk factor for bleeding events and is included in the HAS-BLED (Hypertension, Abnormal renal/liver function, Stroke, Bleeding history or predisposition, Labile INR, Elderly, Drugs/Alcohol concomitantly)score. However, the effects of blood pressure (BP) and changes in BP on bleeding events in patients undergoing percutaneous coronary intervention (PCI) remain poorly understood. This study is aimed to investigate the relationship between systolic BP (SBP) changes during hospitalisation and bleeding events in patients undergoing PCI.
Background: Left atrial (LA) strain reflects not only LA function but also systolic and diastolic left ventricular function. We therefore hypothesize that LA strain may be a comprehensive predictor of heart failure related endpoints after ST-elevation myocardial infarction (STEMI). We aim to assess the impact of LA reservoir strain on the long-term prognosis following ST-elevation myocardial infarction (STEMI).
Unlabelled: One of the most probable and controversial hypotheses regarding the etiology of essential arterial hypertension, is the increase in arterial pressure due to intracranial ischemia, for various reasons, particularly because of cervical osteochondrosis. The daily arterial blood pressure dynamics is of interest when attempting non-pharmacological induced correction of arterial pressure by manual and physical effects on the cervical spine.
Objective: To evaluate daily arterial pressure dynamics in patients with essential arterial hypertension who received non-pharmacological treatment by manual-physical action on the cervical spine (A.
