Article Abstract
Background: Appropriate evaluation of hemodynamic status is vital in the management of acute heart failure (AHF). We aimed to investigate the changes in echocardiographic parameters during very acute phases of AHF and their association with clinical outcomes.
Methods: Patients who were admitted to four Japanese hospitals with AHF were prospectively enrolled. Comprehensive echocardiography and B-type natriuretic peptide (BNP) were assessed both on admission and the second day.
Results: A total of 271 patients (80 ± 12 years old, 52 % male) was included. Overall, transmitral E velocity, E/A, tricuspid regurgitation pressure gradient (TRPG), and inferior vena cava diameter significantly decreased, and stroke volume and left ventricular ejection fraction showed a significant increase by the second day, whereas E/e' did not change. On the second day, BNP increased in 50 patients (18 %). Despite similar baseline characteristics, patients with increased BNP showed a significantly smaller improvement in transmitral flow parameters (E and A velocity, E/A, and flow patterns) and a smaller decrease in TRPG compared with patients with decreased BNP. Other echocardiographic parameter changes were not different between the groups. A combination of improvement in transmitral flow and TRPG was significantly associated with 90-day and 1-year composite events of all-cause death and heart failure hospitalization after adjustment by the Get With the Guidelines-Heart Failure risk score.
Conclusions: Echocardiographic parameters show a dynamic change in the very acute phase of AHF. Several parameters, such as the transmitral flow and TRPG might be useful in monitoring favorable hemodynamic change.

Arterial Stiffness in HFpEF: From Clinical Insight to Bedside Action.
Cardiol Rev

From the Department of General Medicine, J.S.S. Medical College, JSS Academy of Higher Education and Research, Mysuru, India.
Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of all heart failure cases and is increasing in prevalence due to aging populations and comorbidities such as hypertension and diabetes. While echocardiography remains the diagnostic cornerstone, many patients with preserved ejection fraction present with nonspecific symptoms and ambiguous diastolic indices, leading to diagnostic uncertainty and therapeutic delay. Arterial stiffness-quantified by pulse wave velocity, augmentation index, and cardio-ankle vascular index)-is emerging as a key contributor to HFpEF pathophysiology.

Background: Acute myocardial infarction in the elderly often leads to significant left ventricular structural remodeling, which adversely affects prognosis. This study aims to evaluate the effects of intensive rosuvastatin therapy on markers of ventricular remodeling and cardiac function following percutaneous coronary intervention (PCI) in elderly patients with ST-segment elevation myocardial infarction (STEMI).
Methods: This study enrolled 100 patients aged ≥60 years with STEMI who underwent emergency PCI.

Background: Pulmonary Hypertension (PH) is a significant contributor to cardiac mortality in Dilated Cardiomyopathy (DCM) patients. Inflammatory processes and oxidative stress play pivotal roles in the advancement of Pulmonary Hypertension (PH). The Monocyte-to-High-- Density-Lipoprotein Cholesterol Ratio (MHR), a newly identified biomarker indicative of inflammatory and oxidative stress, has not been extensively researched in the context of pulmonary hypertension, especially within the scope of dilated cardiomyopathy.

Background: Accurate measurement of echocardiographic parameters is crucial for the diagnosis of cardiovascular disease and tracking of change over time; however, manual assessment requires time-consuming effort and can be imprecise. Artificial intelligence has the potential to reduce clinician burden by automating the time-intensive task of comprehensive measurement of echocardiographic parameters.
Objectives: The purpose of this study was to develop and validate open-sourced deep learning semantic segmentation models for the automated measurement of 18 anatomic and Doppler measurements in echocardiography.

Rationale And Objectives: This study aimed to investigate the role of cardiac magnetic resonance (CMR)-derived left atrial (LA) strain parameters in evaluating early cardiac dysfunction in hypertensive patients and to assess their diagnostic utility for left ventricular diastolic dysfunction (LVDD).
Methods: A total of 150 hypertensive patients and 60 healthy controls were retrospectively enrolled, with all participants undergoing both echocardiographic and CMR examinations. Hypertensive patients were stratified by LVDD severity based on current guidelines.
