Infective endocarditis is an infection of the inner surface of the heart (endocardium), usually the valves. [1] Signs and symptoms may include fever, small areas of bleeding into the skin, heart murmur, feeling tired, and low red blood cell count.
In a prediction rule study, investigators identify a consecutive group of patients who are suspected of having a specific disease or outcome. The investigators then obtain a standard set of clinical observations on each patient and a test or clinical follow-up to define the true state of the patient.
The TIMI risk score can identify high risk patients in ST-elevation and non-ST segment elevation MI ACS [30] [31] and has been independently validated. [32] [33] Based on a global registry of 102,341 patients, the GRACE risk scoreestimates in-hospital, 6 months, 1 year, and 3-year mortality risk after a heart attack. [34]
Because risk scores such as the Framingham Risk Score give an indication of the likely benefits of prevention, they are useful for both the individual patient and for the clinician in helping decide whether lifestyle modification and preventive medical treatment and for patient education, by identifying men and women at increased risk for future cardiovascular events.
Propensity scores are used to reduce confounding by equating groups based on these covariates. Suppose that we have a binary treatment indicator Z, a response variable r, and background observed covariates X. The propensity score is defined as the conditional probability of treatment given background variables:
HeartScore is the interactive version of SCORE - Systematic COronary Risk Evaluation [1] - a cardiovascular disease risk assessment system initiated by the European Society of Cardiology, using data from 12 European cohort studies (N=205,178) covering a wide geographic spread of countries at different levels of cardiovascular risks.
Subacute bacterial endocarditis; Other names: Endocarditis lenta: Vegetation of tricuspid valve by ECHO: Specialty: Cardiology Symptoms: Malaise, weakness [1] Causes: Streptococcus mutans, mitis, sanguis or milleri bacteria [2] [3] Diagnostic method: Blood culture specimens over 24-hour period/analysis [4] Treatment: Intravenous penicillin [2]
Endocarditis is an inflammation of the inner layer of the heart, the endocardium.It usually involves the heart valves.Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
