“…Because of the extreme similarities between two reported pheochromocytoma‐induced TS cases, one case which was reported later was excluded . In total, 156 cases reports (107 cases with PPGL‐induced TS, 42 cases epinephrine‐induced TS, and 7 cases norepinephrine‐induced TS) constitute the patient cohort for the meta‐analysis. Among the cases included were two non‐English case reports (one case in Swedish and one in German) where enough information could be obtained.…”

Innumerable physical stress factors including externally administered catecholamines, and pheochromocytomas and paragangliomas (PPGLs) have been reported to trigger Takotsubo syndrome (TS). A systematic search of PubMed/MEDLINE identified 156 patients with catecholamine-induced TS up to December 2017. Data were compared within the catecholamine-induced TS cohort, but some comparisons were also done to a previously published large all-TS cohort (n = 1750). The mean age was 46.4 ± 16.4 years (72.3% women). The clinical presentation was dramatic with high complication rates in (68.2%, n = 103; multiple complications 34.6%, n = 54). The most common TS ballooning pattern was apical or mid-apical (45.2%, n = 69), followed by basal pattern (28.8%, n = 45), global pattern (16.0%, n = 25), midventricular (8.3%, n = 13), focal (0.6%, n = 1), and unidentified pattern (1.9%, n = 3).There was an increase in the prevalence of apical sparing ballooning pattern compared to all-TS population (37.7% vs 18.3%, P < .00001). Higher complication rates were observed in TS with global ballooning pattern compared to apical ballooning pattern (23/25, 92% vs 38/65, 58.5%; P = .0022). Higher complication rates were observed in patients with age < 50 years than patients >50 years (73/92, 79.3% vs 29/56, 51.8%, P = 0.0009). Recurrence occurred exclusively in patients with PPGLinduced TS (18/107 patients, 16.8%). PPGL-induced TS was characterized by more global ballooning's pattern (22/104, 21.2% vs 3/49, 6.1%, P = 0.02), and lower left ventricular ejection fraction (25.54 ± 11.3 vs 31.82 ± 9.93, P = 0.0072) compared to exogenous catecholamine-induced TS. In conclusion, catecholamine-induced TS was characterized by a dramatic clinical presentation with extensive left ventricular dysfunction, and high complication rate.
