HAS-BLED is a scoring system developed to assess 1-year risk of major bleeding in people taking anticoagulants for atrial fibrillation (AF). It was developed in 2010 with data from 3,978 people in the Euro Heart Survey. [1] Major bleeding is defined as being intracranial bleedings, hospitalization, hemoglobin decrease > 2 g/dL, and/or transfusion.
The CHADS 2 score and its updated version, the CHA 2 DS 2-VASc score, are clinical prediction rules for estimating the risk of stroke in people with non-rheumatic atrial fibrillation (AF), a common and serious heart arrhythmia associated with thromboembolic stroke.
The European Heart Rhythm Association score of atrial fibrillation (or EHRA score) is a classification system for the extent of atrial fibrillation.It places patients in one of four categories based on how much they are limited during physical activity; the limitations/symptoms are in regard to normal breathing and varying degrees in shortness of breath and/or angina.
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. The SCORE ...
QRISK3 (the most recent version of QRISK) is a prediction algorithm for cardiovascular disease (CVD) that uses traditional risk factors (age, systolic blood pressure, smoking status and ratio of total serum cholesterol to high-density lipoprotein cholesterol) together with body mass index, ethnicity, measures of deprivation, family history, chronic kidney disease, rheumatoid arthritis, atrial ...
Atrial fibrillation is associated with an increased risk of heart failure, dementia, and stroke. [3] [12] It is a type of supraventricular tachycardia. [14] Atrial fibrillation frequently results from bursts of tachycardia that originate in muscle bundles extending from the atrium to the pulmonary veins. [15]
Not only coronary heart disease (CHD) events but also further risks can be predicted. Risk prediction models for cardiovascular disease outcomes other than CHD events have also been developed by the Framingham Heart Study researchers. Amongst others, a risk score for 10-year risk for atrial fibrillation has been developed. [25] [26]
For example, a risk of 9 out of 10 will usually be considered as "high risk", but a risk of 7 out of 10 can be considered either "high risk" or "medium risk" depending on context. The definition of the intervals is on right open-ended intervals but can be equivalently defined using left open-ended intervals ( τ j − 1 , τ j ] {\displaystyle ...
