Heart failure (HF) with normal ejection fraction - the isolated diastolic heart failure, depicts increasing prevalence and health care burden in recent times. Having less mortality rate compared to systolic heart failure but high morbidity, it is evolving as a major cardiac concern. With increasing clinical use of Left atrial volume (LAV) quantitation in clinical settings, LAV has emerged as an important independent predictor of cardiovascular outcome in HF with normal ejection fraction. This article is intended to review the diastolic and systolic heart failure, their association with left atrial volume, in depth study of Left atrial function dynamics with determinants of various functional and structural changes.

Aims: The PARACHUTE-HF trial (NCT04023227) is evaluating the effect of sacubitril/valsartan compared with enalapril on a hierarchical composite of cardiovascular events (cardiovascular death, first heart failure hospitalization), and change in N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels in participants with heart failure and reduced ejection fraction (HFrEF) caused by chronic Chagas cardiomyopathy (CCC). We describe the baseline characteristics of participants in PARACHUTE-HF compared with prior HFrEF trials.
Methods And Results: PARACHUTE-HF, a multicentre, active-controlled, open-label trial, enrolled 922 participants with confirmed CCC, New York Heart Association (NYHA) functional class II-IV, and left ventricular ejection fraction (LVEF) ≤40%.

Introduction: Repaired total anomalous pulmonary venous connection (TAPVC) patients with preoperative pulmonary venous obstruction (PVO) have reductions in echocardiographic metrics, such as left atrial reservoir function and pulmonary venous variability index (PVVI). We hypothesized reduced preoperative left atrial strain mechanics in isolated TAPVC patients serve as risk factors for postoperative PVO. We also evaluated echocardiographic metrics and clinical characteristics associated with preoperative and postoperative PVO, as well as compared these to healthy controls.

Background: Ischemia with non-obstructive coronary arteries (INOCA) represents a diagnostic and therapeutic challenge, often related to coronary microvascular dysfunction (CMD). Identifying non-invasive electrocardiographic markers that predict ischemia in this population remains a clinical priority. P-wave peak time (PWPT), reflecting atrial conduction delay, has been linked to ischemic pathophysiology.

Background: Peripartum cardiomyopathy (PPCM) is a rare, life-threatening form of heart failure occurring in late pregnancy or postpartum, with variable clinical course and outcomes. We report preliminary clinical and echocardiographic findings from a national Italian registry of PPCM patients METHODS: The study was approved by the institutional Ethics Committee and registered at ClinicalTrials.gov (NCT05878041).
