The COVID-19 infection adversely affects the cardiovascular system. Transthoracic echocardiography has demonstrated diagnostic, prognostic and therapeutic utility. We report biventricular myocardial strain in COVID-19. Biventricular strain measurements were performed for 12 patients. Patients who were discharged were compared with those who needed intubation and/or died. Seven patients were discharged and five died or needed intubation. Right ventricular strain parameters were decreased in patients with poor outcomes compared with those discharged. Left ventricular strain was decreased in both groups but was not statistically significant. Right ventricular strain was decreased in patients with poor outcomes and left ventricular strain was decreased regardless of outcome. Right ventricular strain measurements may be important for risk stratification and prognosis. Further studies are needed to confirm these findings.
COVID-19 感染对心血管系统有不良影响。经胸超声心动图具有诊断、预后和治疗作用。我们报告了 COVID-19 中的双心室心肌应变。对 12 名患者进行了双心室应变测量。将出院患者与需要插管和/或死亡的患者进行比较。7 名患者出院，5 名患者死亡或需要插管。与出院患者相比，预后不良的患者右心室应变参数降低。两组的左心室应变均降低，但无统计学意义。预后不良的患者右心室应变降低，而左心室应变无论结局如何均降低。右心室应变测量可能对风险分层和预后很重要。需要进一步的研究来证实这些发现。
