AI Article Synopsis
- The study investigated left ventricular remodeling (LVR) in patients with acute STEMI who were treated with primary percutaneous coronary intervention (PCI), focusing on the connection between early left ventricular dilation and later LVR outcomes.
- Out of 301 patients, 18.9% experienced LVR, with significant differences in left ventricular end-diastolic volume (LVEDV) changes between those with LVR and those without during follow-up.
- Early measurement of changes in LVEDV after discharge and at 1 month was effective in predicting late LVR at the 6-month mark, suggesting that consistent monitoring may improve patient outcomes.
Article Abstract
Backgroud: Left ventricular remodeling (LVR) is a major predictor of adverse outcomes in patients with acute ST-elevation myocardial infarction (STEMI). This study aimed to prospectively evaluate LVR in patients with STEMI who were successfully treated with primary percutaneous coronary intervention (PCI) and examine the relationship between early left ventricular dilation and late LVR.
Methods: Overall 301 consecutive patients with STEMI who underwent primary PCI were included. Serial echocardiography was performed on the first day after PCI, on the day of discharge, at 1 month, and 6 months after discharge.
Results: Left ventricular remodeling occurred in 57 (18.9%) patients during follow-up. Left ventricular end-diastolic volume (LVEDV) reduced from day 1 postoperative to discharge in the LVR group compared with that in the non-LVR (n-LVR) group. The rates of change in LVEDV (ΔLVEDV%) were -5.24 ± 16.02% and 5.05 ± 16.92%, respectively (p < 0.001). LVEDV increased in patients with LVR compared with n-LVR at 1-month and 6-month follow-ups (ΔLVEDV% 13.05 ± 14.89% vs. -1.9 ± 12.03%; 26.46 ± 14.05% vs. -3.42 ± 10.77%, p < 0.001). Receiver operating characteristic analysis showed that early changes in LVEDV, including ΔLVEDV% at discharge and 1-month postoperative, predicted late LVR with an area under the curve value of 0.80 (95% confidence interval 0.74-0.87, p < 0.0001).
Conclusions: Decreased LVEDV at discharge and increased LVEDV at 1-month follow-up were both associated with late LVR at 6-month. Comprehensive and early monitoring of LVEDV changes may help to predict LVR.

An atrial septal defect (ASD) is a common congenital heart anomaly that results in irregular blood flow between the systemic and pulmonary circulations due to an opening in the atrial septum. Ostium secondum ASD accounts for a large proportion of these defects and often goes unnoticed during childhood and adolescence. Pulmonary hypertension (PH), affecting a significant number of patients with ostium secondum ASD, is associated with functional limitations, heart failure, and tachyarrhythmias.

Nondilated left ventricular cardiomyopathy (NDLVC) is a newly defined category of cardiomyopathy. We sought to evaluate and compare the phenotype of NDLVC with DCM using cardiac magnetic resonance (CMR) imaging and to investigate the prognostic significance of these conditions. One hundred and fifty patients suspected of having cardiomyopathy referred for CMR were recruited.

Background: Risk stratification for sudden cardiac death (SCD) in patients with nonischemic cardiomyopathy (NICM) remains challenging.
Objectives: This study aimed to investigate the impact of epicardial adipose tissue (EAT) on SCD in NICM patients.
Methods: Our study cohort included 173 consecutive patients (age 53 ± 14 years, 73% men) scheduled for primary prevention implantable cardioverter-defibrillators (ICDs) implantation who underwent preimplant cardiovascular magnetic resonance.
Background: Cardiovascular diseases are the primary cause of nonobstetric morbidity and mortality in pregnant women worldwide. Pakistan's high maternal and neonatal mortality rates underscore the need for effective screening protocols to detect cardiovascular diseases during pregnancy.
Objectives: The objective of this study was to assess the prevalence and factors associated with structural heart disease among pregnant women without active cardiorespiratory symptoms (no symptoms or symptoms attributed to pregnancy) attending routine antenatal appointments.

Background: Population-based analyses may reduce uncertainty related to referral bias and/or incomplete follow-up.
Objectives: This study analyzed long-term mortality and durability of mitral valve repair in a geographically defined population with clinical and echocardiographic follow-up.
Methods: We used the Rochester Epidemiology Project to identify 153 Olmsted County patients who underwent mitral valve repair for degenerative regurgitation from 1993 to 2018.
