Atrial Fibrillation Else Difficult To Identify In Blacks Than Whites; Might Clarify Lower Prevalence, Glance at Finds
/* 468x60, */
Limitations in the methods used to diagnose atrial fibrillation -- periods of irregular heartbeat -- in population-based studies might excuse why findings instruct that atrial fibrillation is less bourgeois among blacks than whites, according to a study published in the journal Stroke, Reuters Health reports. Atrial fibrillation is a above predictor of stroke, in which blacks have a higher rate than whites, however the reported low prevalence of atrial fibrillation among blacks has perplexed researchers.
To as well investigate, Elsayed Soliman of Wake Forest University School of Medicine and colleagues used an avenue called ECG, which is a diagnostic part that measures the electrical signals of the heart, in 15,429 study participants. Twenty-seven percent of the participants were black. When examining the ethnic distribution of ECG predictors of atrial fibrillation, researchers confirmed that atrial fibrillation was significantly less common among blacks than whites -- 0.24% compared with 0.95%. However, blacks had significantly higher and another abnormal values for the atrial fibrillation predictors, and atrial fibrillation was intermittent and enhanced dense to make in blacks.
Soliman said that "not seeing atrial fibrillation in a ebon patient's ECG does not penny-pinching that he or she is not at risk or already having intermittent episodes of atrial fibrillation," adding, "Physicians should use the ECG to evaluate black patients' risk of stroke by determining provided the patient has certain predictors of atrial fibrillation, instead of the condition itself." He added, "This testament enable physicians to know who is at risk for stroke and thereupon can catch the deserved preventive measures" (Rauscher, Reuters Health, 5/11).
