“…TTC is more prevalent with increasing age, as <10% of recorded cases have occurred in individuals <55 years of age. Reverse TTC is a rare variant of TTC and accounts for approximately 2-5% of TTC cases and involves less severe hemodynamic compromise compared to typical TTC [4]. rTTC also involves higher level of Troponin I elevation (13.1 ng/ml v. 1.6 ng/ml; p=0.001) and lower levels of B-type natriuretic peptide (BNP) (613.3 pg/ml v. 4987 pg/ml; p=0.020) when compared to typical TTC, further distinguishing it clinically [5].…”

Takotsubo cardiomyopathy (TTC) is a reversible form of myocardial injury characterized by transient systolic and diastolic dysfunction secondary to regional left ventricle (LV) wall motion abnormalities. We present a case of a rare variant of TTC, termed reverse TTC (rTTC), involving basal hypokinesis with apical hyperkinesis accounting for less than 5% of identified cases of TTC. Our patient is a 49-year-old Hispanic female who presented for evaluation of dyspnea. She was diagnosed with acute asthma exacerbation. The patient admitted to more frequent use of her albuterol rescue inhaler. Over the course of her hospitalization the patient had elevation of Troponin I and underwent an echocardiogram and coronary angiogram, which revealed the diagnosis of rTTC in the setting of inhaled beta agonist overuse for acute asthma exacerbation. Our case highlights the importance of adequately managing asthma to prevent exacerbation and overuse of inhaled sympathomimetic agents in an effort to decrease the incidence of TTC in the asthmatic population.
