Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection has frequent acute cardiovascular manifestations, but long-term sequelae are yet to be described. Our main objective is to describe the echocardiographic findings of patients with a previous SARS-CoV-2 infection.
A single-center prospective study was conducted. Patients who tested positive for SARS-CoV-2 were selected and submitted to a transthoracic echocardiogram six months after infection. A complete echocardiographic assessment was performed, including tissue Doppler, E/E' ratio, and ventricular longitudinal strain. Patients were divided into two subgroups according to their need for admission to the ICU.
A total of 88 patients were enrolled. The mean values and respective standard deviations of the echocardiographic parameters were as follows: left ventricular ejection fraction 60.8 ± 5.9%; left ventricular longitudinal strain 17.9 ± 3.6%; tricuspid annular plane systolic excursion 22.1 ± 3.6 mm; a longitudinal strain of the free wall of the right ventricle 19.0 ± 6.0%. We found no statistically significant differences between subgroups.
At the six-month follow-up, we found no significant impact of past SARS-CoV-2 infection on the heart using echocardiography parameters.
严重急性呼吸综合征冠状病毒2（SARS-CoV-2）感染常伴有急性心血管表现，但长期后遗症尚未见报道。我们的主要目的是描述既往感染SARS-CoV-2患者的超声心动图检查结果。
进行了一项单中心前瞻性研究。选取SARS-CoV-2检测呈阳性的患者，并在感染后6个月进行经胸超声心动图检查。进行了完整的超声心动图评估，包括组织多普勒、E/E'比值和心室纵向应变。根据患者是否需要入住重症监护病房将其分为两个亚组。
共纳入88例患者。超声心动图参数的平均值及各自的标准差如下：左心室射血分数60.8±5.9%；左心室纵向应变17.9±3.6%；三尖瓣环平面收缩期位移22.1±3.6mm；右心室游离壁纵向应变19.0±6.0%。我们发现亚组之间无统计学显著差异。
在6个月的随访中，我们发现既往SARS-CoV-2感染对心脏的超声心动图参数无显著影响。
