Effect of serum electrolytes within normal ranges on QTc prolongation: a cross-sectional study in a Chinese rural general population |pdf=|usr=}}{{30157775}} gab.com Text Effect of serum electrolytes within normal ranges on QTc prolongation: a cross-sectional study in a Chinese rural general population JO: BMC Cardiovasc Disord http://www.kidney.de/pget.php?&tw=1&pmid=30157775 #FOAvip BACKGROUND: Many previous clinical studies have reported that prolongation of the QT interval corrected for heart rate (QTc) is associated with an increased risk of sudden cardiac death and all-cause mortality. This study aimed to explore associations between serum electrolytes and QTc prolongation in the north-eastern Chinese rural general population. METHODS: We performed a cross-sectional study including 10,334 (4820 men and 5514 women) from the general population aged >/=35 years in the Liaoning Province from 2012 to 2013. Anthropometric measurements, laboratory examinations and self-reported lifestyle factor information, echocardiography and electrocardiogram were collected by trained personnel. The associations between serum electrolytes and QTc prolongation were tested using multiple linear regression and logistic regression analyses. RESULTS: The mean QTc interval were 415.6 +/- 18.8 and 470.1 +/- 23.1 ms in normal group and QTc prolongation group respectively. The prevalence of QTc prolongation increased significantly with a decrease in serum potassium and an increase in magnesium. Stepwise multiple linear regression showed that age, hypertension, waist circumference were prominently positive associated with QTc interval both in male and female population. But serum potassium was significantly inversely associated with QTc interval. Serum magnesium and calcium also showed a positive relationship with QTc interval. Furthermore, multiple logistic regression found that lower quartile of serum potassium had higher risk for QTc prolongation, especially in female population (Q2 vs. Q4: OR: 1.54, 95%CI: 1.01-2.35; Q1 vs. Q4: OR: 2.02, 95%CI: 1.36-3.01). In addition, the higher serum magnesium increased the risk of QTc prolongation, which was significantly only in male population. CONCLUSIONS: In present Chinese rural general population, even with normal range, a decrease in serum potassium and an increase in serum magnesium are important risk factors for QTc prolongation.
