Abstract:
Objective:To investigate the clinical features of pregnant associated Takotsubo cardiomyopathy (PTCM).Methods:We reviewed reported PTCM cases published from January 2007 to June 2022 using the keywords "Tako-tsubo cardiomyopathy""Takotsubo cardiomyopathy" "stress cardiomyopathy" AND "parturition" "pregnancy" "cesarean delivery" "postpartum" "peripartum" "eclampsia" "abortion" in Pubmed and Web of Science databases and the corresponding Chinese words in Wanfang and Chinese Medical Journal Network. Age, obstetric history, mode of delivery, mode of anesthesia, etiological factors, clinical manifestations, treatment, and prognosis of PTCM were recorded. Descriptive statistical analysis was adopted.Results:A total of 55 articles were included, covering 60 patients with PTCM. (1) Age and time of onset: The age of onset was (32.4±6.0) years old. PTCM occurred most frequently during labor [42% (25/60)] and within one day postpartum [32% (19/60)] and during the gestational period [13%(8/60), 33.0 weeks (24.5-37.7 weeks)]. (2) Delivery-related factors: There were 38% (16/42) primiparas and 60% (25/42) multiparas. Among them, 67% (38/57) and 18% (10/57) were delivered by cesarean section and vaginal delivery, respectively. PCTM often lacks obvious triggers [40% (24/60)], with the most common inducing factor being pregnancy-related diseases [27% (16/60)]. (3) Clinical features: The initial symptoms of PTCM were dyspnea [44% (26/59)], followed by chest pain accompanied by dyspnea [17% (10/59)]. The most common subtype of PTCM was the apical type [45% (26/58)], followed by the basal type [24% (14/58)], while the biventricular type was the least common [3% (2/58)] in the PTCM classification. The left ventricular ejection fraction was (31.6±12.1) % at the onset of PTCM, which recovered to (58.2±7.6) % at discharge. PCTM was often complicated by pulmonary edema [67% (40/60)] and cardiogenic shock [55% (33/60)]. (4) Treatment and prognosis: Patients with PCTM usually require noninvasive or invasive ventilator-assisted ventilation [40% (23/58)]. One pregnant woman and five neonates died, while the remaining patients recovered well.Conclusions:PTCM should be considered in differential diagnosis of patients experiencing dyspnea and chest pain during labor and pregnancy. PTCM patients are younger and have more pulmonary edema and cardiogenic shock. Mechanical ventilation is often required, but the prognosis is favorable.
