Possible predictive factors for recovery of left ventricular systolic function in Takotsubo cardiomyopathy.

Takotsubo cardiomyopathy (TTC) is a transient systolic dysfunction of the left ventricle which is usually seen in elderly women, often following a physical or emotional stressful event. Little is known about the prognostic factors affecting the recovery of systolic function. Thirty-six patients diagnosed with TTC from January 2006 to January 2017 at our hospital were included. Median time to recovery of ejection fraction (EF) was calculated to be 25 days. Early recovery of ejection fraction was defined as less than or equal to 25 days (group 1) and late recovery was defined as more than 25 days (group 2). Demographic and clinical factors were compared between the groups. Fifty percent patients had early recovery of EF with a mean time to recovery of 7.11 days and 50% had late recovery of ejection fraction with a mean time to recovery of 58.38 days. Younger age at presentation was associated with early recovery of systolic function (58.83 ± 2.7 years vs. 67.33 ± 2.7 years, p = 0 .032). Presence of an identifiable triggering event was associated with early recovery (83% in group 1 vs. 50% in group 2, p = 0.034). Generalized anxiety disorder was seen more commonly in the group with early recovery (78% in group 1 vs. 45% in group 2, p = 0.040). In conclusion, younger age, generalized anxiety disorder and presence of triggering event were seen more commonly in patients with early recovery of left ventricular systolic function in Takotsubo cardiomyopathy.

Noncompaction Cardiomyopathy with Charcot-Marie-Tooth Disease.

We report a case of a 53-year-old female presenting with a new-onset heart failure that was contributed secondary to noncompaction cardiomyopathy. The diagnosis was made by echocardiogram and confirmed by cardiac MRI. Noncompaction cardiomyopathy (also known as ventricular hypertrabeculation) is a newly discovered disease. It is considered to be congenital (genetic) cardiomyopathy. It is usually associated with genetic disorders and that could explain the genetic pathogenesis of the non-compaction cardiomyopathy. Our case had a history of Charcot-Marie-Tooth disease. There is a high incidence of arrhythmia and embolic complications. The treatment usually consists of the medical management, defibrillator placement, and lifelong anticoagulation. Heart transplantation will be the last resort.
