EurjheartFail: Left atrium function indicator can predict low risk group heart failure

Within a global, heart failure (HF) is the main cause of cardiovascular mortality and incidence. The prevalence of HF in Western countries is approximately 1-2%, and 5 years of mortality is as high as 35%.

Recently, a research article published a research article on the Cardiovascular Of Heart Failure, which is aiming to investigate the left ventricle (LA) parameters measured by chest ultrasonic cardiac, as a community queue (HF) forecast The performance of the indicator.

In this large common population study (n = 2221), participants accepted an echocardiographic examination. The researchers measures the maximum and minimum LA volumes associated with the surrounding area of ​​the participants, and calculate the LA emptying fraction (LAEF) and LA expansion index (laei).

Among the 1951 participants without atrial fibrillation or obvious valve disease, the average age of 59 ± 16 years, 58% is women. At baseline, 1% (n = 16) participant LV radiation fraction is less than 50%, and 44% of participants have high blood pressure, and 10% of participants have diabetes. During follow-up (in the median is 15.8 years, IQR is 11.3 - 16.2), 187 (10%) participants were diagnosed with HF. Participants who have been diagnosed with HF during follow-up have larger Lavimax and Lavimin compared to participants without HF, with larger Lavimax and Lavimin, as well as lower Laef and laei. In the undecomposed analysis, Lavimax, Lavimin, LaEf and laEi are HF predictors. After the clinical and echocardiographic parameters are adjusted, only Lavimin is still an independent predictor that occurs in HF (HR of 1 SD is 1.22 (1.01-1.47), p = 0.038).

It can be seen that in the general population, Lavimin is an independent predictor that occurs HF. LaviMax is the only LA measurement index in conventional echocardiographic examinations, not an independent prediction indicator of HF.
