* Leadless cardiac devices including the CardioMEMS device, implantable loop recorder, and RV leadless pacemaker are important tools in the treatment and management of patients with common cardiac conditions such as heart failure, cardiac syncope
, and arrhythmias.
Syncope is classified into cardiac syncope
, orthostatic hypotension (OH) and reflex (neurally mediated) mechanisms.
If you have a tilt table there, terrific, but I want to remind everybody of one thing about tilts: Do remember that people with very serious cardiac syncope
that can lead to sudden death can also have a positive tilt.
About half the time, diagnosis is predicted correctly with vasovagal syncope, postural syncope, and cardiac syncope
. About 30 percent of cases are suspected, and 20 percent of cases are unknown, which means further testing and evaluation is needed (ECG, EEG, MRI, etc.
Results: Of the 100 patients evaluated, 22(22%) were diagnosed with cardiac syncope. Of them, 13(59.1%) patients had a positive and 9(40.9%) had a negative heart-type fatty acid binding protein result.
Cardiac syncope has the highest mortality and morbidity rates among all types of syncope and aetiology consists of acute coronary syndromes (ACS), arrhythmias and structural heart diseases.1 Traditionally troponins are routinely used in diagnosis of cardiac syncope but given the relatively delayed positivity and peak times of them, use of markers such as heart-type fatty acid binding protein (H-FABP) that appear earlier in serum has recently begun to increase.5
The present study was planned to determine the value of bedside H-FABP in diagnosis of cardiac syncope in patients presenting to ED with syncope or near-syncope.
is the most dangerous form of syncope, but it is also probably the least common--about 8%-10% of all syncope is cardiac in nature, Dr.
"Persons with cardiac syncope
constitute a high-risk group predisposed to morbidity and premature mortality from cardiovascular disease who should be monitored closely," they said.
