Aims: The aim of this study was to assess the echocardiographic distribution of regional wall motion abnormalities (RWMA) in patients with tako-tsubo cardiomyopathy (TTC) compared with anterior ST-elevation myocardial infarction (ant-STEMI).
Methods And Results: Thirty-seven TTC and 37 ant-STEMI patients underwent standard echocardiographic examination at the time of hospital admission. RWMA and the involvement of the left ventricular territories supplied by each coronary artery according to the American Society of Echocardiography classification were reported. TTC patients showed a lower left ventricular ejection fraction (37.6 ± 5.1 vs. 40.9 ± 3.7%; P = 0.002) and a higher wall motion score index (WMSI; 1.98 ± 0.2 vs. 1.51 ± 0.14; P < 0.001) compared with ant-STEMI patients. No significant differences were observed between groups with regard to detection of RWMA in the territory supplied by the left anterior descending coronary artery (LAD) (37 vs. 37; P = 1). Conversely, in TTC patients, the territories supplied by the LAD/left circumflex coronary artery (LCX) (37 vs. 31; P = 0.011), LAD/right coronary artery (RCA) (34 vs. 13; P < 0.001), RCA (33 vs. 5; P < 0.001), and RCA/LCX (31 vs. 2; P < 0.001) were more frequently involved. A cut-off value of WMSI ≥1.75 (area under the curve 0.956) and for the number of territories with RWMA ≥4 (AUC = 0.928) predicted TTC with a sensitivity of 83 and 84% and a specificity of 100 and 97%, respectively.
Conclusion: Echocardiography revealed a distinctive pattern of contractility in TTC patients, characterized by symmetrical RWMA extending equally into the territory of distribution of all coronary arteries.

Importance: Drug-coated balloon (DCB) angioplasty has emerged as an alternative to drug-eluting stent (DES) implantation for percutaneous coronary intervention (PCI) in patients with coronary in-stent restenosis (ISR) as well as de novo coronary artery disease.
Observations: DCBs are balloons coated with antiproliferative agents and excipients, whose aim is to foster favorable vessel healing after appropriate lesion preparation. By providing homogeneous antiproliferative drug delivery in the absence of permanent foreign body implantation, DCBs offer multiple advantages over DES, including preservation of vessel anatomy and function and positive vessel remodeling.

Background: The role of NT-proBNP as a cardiac biomarker for predicting short-term major adverse cardiovascular events (MACEs) in acute coronary syndrome (ACS) remains unclear.
Aims: This study investigated the utility of the NT-proBNP level for predicting MACEs within a 6-month period in patients with ACS.
Methods: This prospective study included 241 consecutively enrolled adults with ACS between September 2023 and February 2024.

Purpose: This study aimed to systematically review the cost-effectiveness of rivaroxaban plus aspirin (RIV + ASA) versus aspirin (ASA) alone in patients with stable coronary artery disease (CAD) or peripheral artery disease (PAD).
Methods: A systematic review was conducted using leading databases including PubMed, Scopus, and Web of Science core collection. The search was carried out up to June 25, 2024, focusing on identifying full economic evaluation studies comparing the cost-effectiveness of RIV + ASA versus ASA alone in patients with stable cardiovascular diseases (CVDs).

Introduction: Asthma is a complex condition characterized by airway inflammation. Interleukin-6 (IL-6) plays a significant role in asthma pathogenesis through its effects on T cells and its association with pro-inflammatory responses. Both lung and circulating IL-6 levels are elevated in asthma.

Background: Coronary physiology to guide multi-vessel coronary intervention is associated with better outcome. In the presence of a coronary chronic total occlusion (CTO), hemodynamic evaluation of intermediate lesions in the donor coronary artery supplying a CTO territory still has limitations. We aim to evaluate implementing quantitative flow ratio (QFR) in assessing angiographically intermediate lesions of the main donor coronary artery supplying a CTO territory.
