Plexiform Lesions in an Experimental Model of Monocrotalin-Induced Pulmonary Arterial Hypertension
Conclusion The MCT model was able to generate moderate-severe pulmonary arteriopathy associated with secondary right ventricular hypertrophy. The 37-day survival rate was 50%. To our knowledge, this study was the first to note the presence of complex vascular lesions, similar to those observed in patients with severe pulmonary arterial hypertension, in an isolated MCT model.

Oxygen Consumption and Cardiorespiratory Fitness. The Difference between Chronological and Biological Age
Conclusion We developed a classification for CRF and found higher values in all classification ranges of functional capacity in contrast to the Cooper Clinic and FRIEND Registry. Our findings offer a more accurate interpretation of ACR in this large Brazilian population sample when compared to previous standards based on the estimated VO2max.

Depressive Symptoms are Associated with High Levels of Serum Low-Density Lipoprotein Cholesterol in Older Adults with Type 2 Diabetes Mellitus
Conclusion In older adults with T2DM, the presence of DS was associated with LDL-C, HDL-C levels and SBP, even after adjusting for sex, age, physical activity level and functional capacity. (Arq Bras Cardiol. 2020; [online].ahead print, PP.0-0) (Source: Arquivos Brasileiros de Cardiologia)

Severity Index Performance in Predicting Postoperative Complications of Coronary Artery Bypass Grafting
Conclusion APACHE II excelled in predicting neurological and renal complications. None of the indices performed wel l in predicting the other analyzed complications. Therefore, severity indices should not be used indiscriminately in order to predict all complications frequently presented by patients after CABG.
