ECHO-MPS, a dual modality strategy of cardiac imaging to identify myocardial ischemia.

Article Synopsis
- The study aimed to assess the effectiveness of combining resting echocardiography (TTE) and stress myocardial perfusion scintigraphy (MPS) for diagnosing coronary artery disease in patients with stable angina and normal left ventricle (LV).
- Researchers hypothesized that a normal LV on TTE could eliminate the need for resting MPS, thus reducing radiation exposure without sacrificing diagnostic accuracy.
- Results showed that the ECHO-MPS approach achieved similar diagnostic accuracy to the standard method, indicating that stress MPS alone may suffice for patients with normal systolic LV function.
Background: Obesity is one of the major risk factors for the development of heart failure (HF), although the exact underlying mechanism remains unclear. In the clinical setting, assessing the impact of obesity on the cardiovascular system is difficult due to comorbidities.
Objectives: The purpose of this study was to evaluate an independent influence of obesity on the left ventricular (LV) morphology and function.
Background: Renal artery stenosis (RAS) reflects more widespread atherosclerosis deposition and is associated with high morbidity and mortality. According to the guidelines, a discrepancy in the size of the kidneys of over 15 mm found in an ultrasound should initiate the RAS diagnostic algorithm. This study aims to find the optimal threshold for renal asymmetry that better reflects the frequency of a significantly abnormal renal-aortic ratio (RAR), justifying further RAS diagnostic workup, than the currently used cut-off of 15 mm difference in renal diameters.

Objectives: Our aim was to investigate the usefulness of the ultrasound‑based hepatorenal index (HRI) technique and 2 biomarker‑based methods, including the hepatic steatosis index (HSI) and NAFLD logit score for the diagnosis of NAFLD in patients referred for bariatric surgery.
Patients And Methods: A total of 162 patients, including 106 with NAFLD, admitted for bariatric surgery participated in the study.
Background: Obesity increases and surgical weight reduction decreases the risk of atrial fibrillation (AF) and heart failure (HF). We hypothesized that surgically induced weight loss may favorably affect left atrial (LA) mechanical function measured by longitudinal strain, which has recently emerged as an independent imaging biomarker of increased AF and HF risk.
Methods: We retrospectively evaluated echocardiograms performed before and 12.
