Prognostic Value of Isolated Elevated Troponin I Levels in Patients without Acute Coronary Syndrome Admitted to the Emergency Department
Conclusions: Isolated troponin elevation in two consecutive measurements was a strong predictor of survival in ED patients with troponin elevation but without ACS. (Source: Arquivos Brasileiros de Cardiologia)

T1 Mapping in Heart Failure: Prognostic Implications
Conclusions: CMR T1 mapping is feasible for clinical HF evaluation. There was a direct association between higher native T1 values and lower ejection fraction, and with larger LV diameters and volumes, regardless of the etiology of HF. (Source: Arquivos Brasileiros de Cardiologia)

Removal of Transvenous Pacing Leads in Artificial Cardiac Stimulation Systems
Conclusion: Complications and clinical success were observed in 11.5% and 91.8% of the population, respectively. Removal of older atrial and ventricular leads were associated with lower success rates. Longer procedures and blood transfusions were associated with complications.

Percutaneous Removal of Cardiac Leads in a Single Center in South America
Conclusion: Complications and clinical success were observed in 11.5% and 91.8% of the population, respectively. Removal of older atrial and ventricular leads were associated with lower success rates. Longer procedures and blood transfusions were associated with complications.

Walking Training Improve Ambulatorial Blood Pressure Variability in Claudicants
Conclusions: The WT does not change ambulatory BP levels but decreases ambulatory BP variability in patients with PAD. This improvement may have a favorable impact on the cardiovascular risk of patients with symptomatic PAD. (Arq Bras Cardiol. 2021; 116(5):898-905) (Source: Arquivos Brasileiros de Cardiologia)

The Six-Minute Step Test as an Alternative for Functional Capacity Assessment in Patients with Cardiovascular Diseases
Conclusion: An equation for predicting VO2peak based on 6MST results was derived, and a significant association was found between 6MST and VO2peak. The cutoff point for 6MST, which predicts a VO2peak ≥ 20 mL.Kg-1.min-1, was>105 steps. (Arq Bras Cardiol. 2021; 116(5):889-895) (Source: Arquivos Brasileiros de Cardiologia)

Analysis of Revascularization Strategies in Patients with Acute Myocardial Infarction and Cardiogenic Shock - Results from the Portuguese Registry on Acute Coronary Syndromes
Conclusions: Among patients with MI, CS, and MVD included in the ProACS, there was no significant difference between complete and incomplete revascularization during the index hospitalization regarding the occurrence of in-hospital death or MI.
