Figure Lengend Snippet: Overview of methodologies employed in six distinct studies. The first study (intraperitoneal study) scrutinized a preceding model of takotsubo syndrome and the impact of oxygen supplementation. The ‘infusion time study’ assessed varying durations of infusion (ranging from 1 to 60 min). The ‘dose study’ examined a range of isoprenaline dosages (from 0 to 1 mg/kg). The ‘replication study’ served as a reiteration of the infusion time study. The ‘sex study’ investigated the role of female and male sex in the intravenous model. The ‘strain study’ evaluated the effect of different rat strains and breeders on the newly developed takotsubo syndrome model. High-resolution echocardiography was utilized to assess cardiac function and wall motion abnormalities for a period up to 30 days. Parameters, such as mortality rate, incidence and extent of apical akinesia, and timeframe for recuperation of cardiac function, were investigated across the studies.

Figure Lengend Snippet: Evaluation of 30-day mortality and physiological parameters in the intraperitoneal model with oxygen supplementation. ( A ) Oxygen saturation and body temperature during first 60 min. Mean ± SEM. Two-way repeated-measures analysis of variance; n = 18 per group. * P < 0.05, *** P < 0.001 vs. baseline (no O 2 supplementation group); ¤¤¤ P < 0.001 vs. baseline (O 2 supplementation group). ### P < 0.001 between groups (no O 2 vs. O 2 ). ( B ) Electrocardiogram (ECG) changes from baseline (i) to 60 min (v) after induction. ECG changes (ii) occurred in conjunction with increased heart rate and oxygen saturation drop. These changes were dynamic with (iii) and without (iv) oxygen supplementation. ( C ) Although oxygen supplementation increased survival, high 30-day mortality rates were observed. Results presented assuming Weibull distribution; n = 15 per group; P = 0.026. ( D ) Boxplots depicting the extent of akinesia. Oxygen supplementation did not affect the extent of akinesia. Unpaired two sample t -test; n = 8 and 12 per group. P = 0.91. ( E ) The surviving animals in the oxygen supplemented group had better cardiac function at 2 h. Unpaired two sample t -test; n = 8 and 6 per group. P = 0.022. FAC, fractional area change; SpO 2 , oxygen saturation.
