Abstract
- e14011 Background:Variants of the classic Tako-tsubo syndrome or stress induced cardiomyopathy (SC) includes mid ventricular or basal left ventricular wall motion abnormalities. Midcavitary dyskinesia and ballooning is considered a unique presentation, and there is no published data showing midcavitary involvement in cancer patients. Methods: All cancer patients who fulfilled the diagnostic criteria for SC at MD Anderson Cancer Center over a 6–year period were included in the study. We selected and retrospectively reviewed the medical records of 8 patients who had midcavitary SC. Clinical presentation, ECG, laboratory data, transthoracic echocardiogram and left ventriculography results were reviewed. Results: Out of30 cancer patients who fulfilled the diagnostic criteria for SC, 8 patients (26.7%) (4 females, 4 men, mean age 57.37 yo) had midcavitary SC. 62,5 % patients were diagnosed with a solid malignancy. Trigger factors for midcavitary SC were: systemic infection (3 patients with neutropenia), emotional stress (2 patients), chemotherapy (1 patient undergoing treatment with Ibrutinib), and surgical interventions (3 patients). Clinical presentation included chest pain (37.5%), shortness of breath (50%) and non specific symptoms (12.5%). T wave inversion was the most common electrocardiographic presentation (37.5 %), followed by ST elevation (25 %). All patients had changes of the cardiac biomarkers (BNP mean 2224. 4 pg/dl, TN I mean 2. 8 ng/dl, CK-MB mean 14 ng/dl) and significant LV dysfunction (LVEF < 50%). All patients underwent coronary angiography which showed no obstructive CAD; left ventriculography identified basilar and apical hyperkinesis and midventricular hypokinesia. Cancer therapy was interrupted; aspirin and beta blockers were initiated in all patients. The most common complications of midcavitary SC were: respiratory failure requiring intubation (37, 5%), pulmonary edema (25%), and hypotension (25%). No cardiac deaths were registered. None of the patients experienced recurrence of SC. Conclusions: Mid cavitary SC remains a rare entity, and raises further questions about the causal association between the mid cavitary involvement and cancer, and its impact on cancer therapy and overall survival in this cohort of patients.
