Aims: Left atrial (LA) volume index (LAVI) in chronic heart failure (HF) predicts cardiovascular outcomes. However, the association between LAVI reduction during acute decompensated HF (ADHF) and its prognostic potential is limited. We hypothesized that LA reverse remodelling (LARR) after ADHF therapy would be associated with better clinical outcomes.

Article Synopsis
- Limited data exists on the cardiac structure of rugby athletes, prompting a study that examined 114 young Japanese collegiate players using echocardiography and cardiopulmonary exercise testing (CPET).
- The findings revealed that these athletes showed larger left ventricular, atrial, and aortic dimensions compared to previous studies, with forwards and backs presenting different muscular and endurance traits.
- Additionally, 16% displayed abnormal left ventricular geometry, with higher resting systolic blood pressure noted in those with concentric geometry, highlighting unique cardiac remodeling and potential subclinical cardiovascular risks among young athletes.
A 54-year-old male bodybuilder who was abusing anabolic steroids developed an acute ST-segment elevation myocardial infarction after strenuous strength training. Despite optimal use of dual antiplatelet therapy, on day 4 after primary coronary stenting, the patient suffered another acute coronary event due to subacute thrombosis, potentially pre-disposed by anabolic steroid use.

- This study examined the effectiveness of cardiac rehabilitation (CR) on patients recovering from ST-segment elevation myocardial infarction (STEMI) treated with modern medical interventions.
- Among the 145 patients reviewed, those who completed an outpatient CR program showed better outcomes, with an 88% survival rate free of major adverse cardiac and cerebrovascular events (MACCE) compared to 76% in those who did not participate in CR.
- The findings suggest that participating in CR may significantly improve mid-term prognosis and overall health in STEMI patients, with noticeable enhancements in physical fitness metrics post-rehabilitation.
Article Synopsis
- This study investigates the relationship between circulating microRNAs (miRs) and cardiorespiratory fitness in patients recovering from an acute myocardial infarction (MI) through cardiopulmonary exercise testing (CPET).
- It involved 20 patients post-MI, analyzing specific miRs (miR-181a, 181b, 181c, and miR-484) against a control group of 5 healthy individuals.
- The findings suggest that elevated levels of miR-181c and miR-484 may serve as predictive biomarkers for fitness levels after an MI, indicating that higher expressions correlate with better exercise capacity.
