Therapeutic Challenges in Combined Apical Ballooning Syndrome and Acute Pulmonary Decompensation

Apical ballooning syndrome (ABS) is increasingly diagnosed in critical care settings. Widespread application of echocardiography and cardiac enzyme testing has increased its recognition. Our experience of 4 subjects illustrates the association of ABS with a wide spectrum of acute pulmonary disorders seen in critical care settings. All had ABS proven by normal coronary angiogram and subsequent normalization of left ventricular dysfunction. Bronchospasm due to chronic obstructive pulmonary disease exacerbation or cardiac failure warrants the use of beta agonists. ABS, on the other hand, being caused by excess sympathetic activity could potentially improve with beta blockade. Coexistence of ABS and pulmonary disease in critical-care settings presents unique therapeutic challenges and outcomes can be optimized by judicious use of available medical options.
