Initially developed to predict stroke probability in patientswith atrial fibrillation （AF）,t1~1 CHADS2 and CHA2DS2VASCscores are used to predict different outcomes in cardiac pa-tients in both acute and chronic conditions. Thescores were also demonstrated to correlate with mortal-ity. AF also has been associated with mortality indifferent groups of patients, including elderly.

Tilt table test today-state of the art

引用

World Journal of Cardiology 2016年第3期8卷 277-282页

作者： Nicholay Teodorovich moshe swissa Kaplan Medical Center the Hebrew University

A tilt table test(TTT) is an inexpensive, noninvasive tool for the differential diagnosis of syncope and orthostatic intolerance and has good diagnostic yield. The autonomic system malfunction which underlines the reflex syncope is manifested as either hypotension or bradycardia, while an orthostatic challenge is applied. The timing of the response to the orthostatic challenge, as well as the predominant component of the response help to differentiate between various forms of neurocardiogenic syncope, orthostatic hypotension and non-cardiovascular conditions(e.g., pseudosyncope). Medications, such as isoproterenol and nitrates, may increase TTT sensitivity. Sublingual nitrates are easiest to administer without the need of venous access. TTT can be combined with carotid sinus massage to evaluate carotid sinus hypersensitivity, which may not be present in supine position. TTT is not useful to access the response to treatment. Recently, implantable loop recorders(ILR) have been used to document cardioinhibitory reflex syncope, because pacemakers are beneficial in many of these patients, especially those over 45 years of age. The stepwise use of both TTT and ILR is a promising approach in these patients. Recently, TTT has been used for indications other than syncope, such as assessment of autonomic function in Parkinson's disease and its differentiation from multiple system atrophy.
