Popis: Background: Suboptimal blood pressure (BP) control is commonly observed in patients receiving antihypertensive agents, but the relationship between uncontrolled BP and left atrial (LA) impairment remains unknown. Methods: This study enrolled 279 hypertensive patients who had been medicated, as well as 85 matched normal controls. The BP of systolic 140/90 mmHg appeared an independent risk factor associated with the abnormal SEa (odds ratio, 2.957; interval of confidence, 1.614-5.415; p = 0.001). Conclusions: Suboptimal BP control status in hypertensive patients is related to a further reduction of LA myocardial function assessed by the novel 2DSTI free strain, and suboptimal BP might be regarded as a composite risk factor and therefore a simplified treatment target. However, the prognostic value of LA free strain in patients with inability to achieve the BP target needs to be evaluated in future prospective studies.
