Doxorubicin (Dox) is a commonly used anthracycline chemotherapy with a side effect of cardiotoxicity, which may increase the risk of heart failure for cancer patients. Although various studies have demonstrated the cardioprotective property of dapagliflozin (DAPA), a sodium-glucose cotransporter 2 inhibitor, the detailed mechanism underlying its effect on Dox-induced cardiomyopathy is still limited. In this study, we showed that DAPA induced the activation of AKT/PI3K signaling in cardiac myoblast H9c2 cells following Dox treatment, leading to the upregulation of antioxidant HO-1, NQO1, and SOD, as well as an improved mitochondrial dysfunction via Nrf2.

Purpose: This study was designed to identify the relationship between PSs and demographics, including gender and age, acute symptoms, and pre-hospital delay time, in patients with AMI.
Methods: A cross-sectional study design was applied, and a convenience sampling approach was used to recruit 121 patients in the emergency room of a medical center located in southern Taiwan.
Background: Emerging evidence demonstrated dapagliflozin (DAPA), a sodium-glucose cotransporter 2 inhibitor, prevented various cardiovascular events. However, the detailed mechanisms underlying its cardioprotective properties remained largely unknown.
Results: In the present study, we sought to investigate the effects of DAPA on the cardiac ischemia/reperfusion (I/R) injury.
Acute myocardial infarction (AMI) is the most critical event in the disease spectrum of coronary artery disease. To rescue cardiomyocytes in AMI, it is important to restore blood supply as soon as possible to reduce ischemia-induced injury. However, worse damage can occur during the reperfusion phase, called the reperfusion injury.

Exercise ameliorates exercise responses and exercise tolerance in patients receiving chemotherapy. The cardioprotective effect of real-time exercise in breast cancer is still unclear.

Epigallocatechin gallate (EGCG), a well-known anti-oxidant in green tea, has been reported with benefits on metabolic and cardiovascular diseases. This study aimed to explore that EGCG ameliorates homocysteine-induced endothelial cell apoptosis through enhancing the sirtuin 1 (SIRT1)/AMP-activated protein kinase (AMPK) survival signaling pathway.

Acute myocardial infarction (AMI) is the maximum critical cardiovascular event and causes high morbidity and mortality worldwide. The ischemia and reperfusion that occur in AMI cause apoptosis and cellular dysfunction in cardiomyocytes. IL-20, an IL-10 family member, is involved in various inflammatory diseases.

Accumulating evidence indicates that galectin-3 may also promote atherogenesis through inducing endothelial dysfunction. Lectin-like oxidized low-density lipoprotein (oxLDL) receptor-1 (LOX-1), a receptor for oxLDL uptake, contributes to oxLDL-induced endothelial dysfunction.

This study was intended to investigate whether the exercise training intervention could improve the body composition and exercise responses of patients with head and neck (H&N) cancer who are receiving chemotherapy.
Methods: This is a randomized controlled trial.
Background The aim of this study was to determine the influence of various antidiabetic therapies on the relationship between body mass index and all-cause mortality in patients with diabetes mellitus and acute coronary syndrome. Methods and Results This was a prospective, observational study comprising 1193 patients diagnosed with type 2 diabetes mellitus and acute coronary syndrome. The patients were stratified into 4 body mass index categories, and their mortality rates were compared using time-dependent Cox regression analysis using normal weight (body mass index, 18.

Background: Patients with acute coronary syndrome (ACS) and diabetes mellitus (DM) receive less aggressive treatment and have worse outcomes in Taiwan. We sought to explore whether the current practices of prescribing guideline-directed medical therapy (GDMT) for ACS and clinical outcomes have improved over time.
Methods: A total of 1534 consecutive diabetic patients with ACS were enrolled between 2013 and 2015 from 27 hospitals in the nationwide registry initiated by the Taiwan Society of Cardiology (the TSOC ACS-DM Registry).
Scope: Endothelial dysfunction is an important mechanism in the development of atherosclerosis and is thought to be critical for predicting cardiovascular diseases. Previous reports suggested that chlorogenic acid (CGA) is a potent antioxidant and anti-inflammatory compound. The molecular mechanisms underlying the inhibitory effects of CGA on oxLDL-induced oxidative injuries in human endothelial cells are still largely unknown.

Methods: Two interventional cardiologists reviewed the records of all consecutive patients who, between November 2011 and October 2015, had undergone PCI with a GuideLiner or Heartrail ST-01 extension catheter.
Coronary artery disease (CAD) is the primary critical cardiovascular event. Endothelial cell and monocyte dysfunction with subsequent extravagant inflammation are the main causes of vessel damage in CAD. Thus, strategies that repress cell death and manage unsuitable pro-inflammatory responses in CAD are potential therapeutic strategies for improving the clinical prognosis of patients with CAD.

Methods: We recruited 174 ED patients who underwent high-pitch CTA of the aorta because of suspected aortic dissection. We divided these patients into two groups (diseased and control groups) based on whether their clinical data fulfilled the third universal definition of acute myocardial infarction (AMI), specifically an increase in cardiac troponin (cTn) with at least one of the following: (a) symptoms of ischemia; (b) new ST-segment-T wave (ST-T) changes or new left bundle branch block (LBBB); (c) development of pathological Q wave; (d) new loss of viable myocardium or new regional wall motion abnormality; or (e) identification of an intracoronary thrombus by angiography or autopsy.
Obese patients have higher levels of free fatty acids (FFAs) in their plasma and a higher risk of cancer than their non-obese counterparts. However, the mechanisms involved in the regulation of cancer metastasis by FFAs remain unclear. In this study, we found that oleic acid (OA) induced angiopoietin-like 4 (ANGPTL4) protein expression and secretion and conferred anoikis resistance to head and neck squamous cell carcinomas (HNSCCs).

It is unknown whether there has been any change in the causes of death for acute ST-segment elevation myocardial infarction (STEMI) in the era of aggressive reperfusion. We analyzed the direct causes of in-hospital death in patients with STEMI treated with primary percutaneous coronary intervention (PCI) in a tertiary referral center over the past 10 years.We retrospectively analyzed 878 STEMI patients treated with primary PCI in our hospital between January 2005 and December 2014.
