Millions of people worldwide have diabetes, which is diagnosed by fasting blood glucose levels exceeding 126 mg/dL. Regardless of the type of diabetes, prolonged hyperglycemia is damaging to several organs including eyes, kidneys, nerve, and/or heart. The damages are associated with a high risk of morbidity and mortality. Diabetes has been implicated in ischemia in the microvasculature of the target tissues, which occurs due to the insufficient perfusion of tissues. The resulting occlusion and pain affect the quality of life...

PURPOSE: The role of insulin-like growth factor-binding protein-7 (IGFBP-7) in atherosclerosis is still not well-known. The objective of this study was to find out the following: 1) whether IGFBP-7 may act as a biomarker of coronary artery disease (CAD) occurrence and extent; 2) whether IGFBP-7 is potentially related to the classical and new markers of cardiovascular risk (carotid intima-media thickness - cIMT); 3) whether IGFBP-7 may be a marker of mortality in the group of patients with myocardial infarction (MI)...

BACKGROUND: The mouse is the most widely used mammal in experimental biology. Although many clinically relevant in vivo cardiac stressors are used, one that has eluded translation is long-term cardiac pacing. Here, we present the first method to chronically simulate and simultaneously record cardiac electrical activity in conscious mobile mice. We then apply it to study right ventricular pacing induced electromechanical dyssynchrony and its reversal (resynchronization). METHODS AND RESULTS: The method includes a custom implantable bipolar stimulation and recording lead and flexible external conduit and electrical micro-commutator linked to a pulse generator/recorder...

Symptomatic individuals suspected of having myocardial ischemia often have no obstructive atherosclerotic narrowing of epicardial coronary arteries. Abnormal coronary vascular reactivity, and in particular, coronary artery vasospasm (CAS), may be an explanation in a subset of these patients. Psychological factors play an important role in ischemic heart disease, but their role in CAS is not clear; autonomic dysfunction and increased inflammation are two prevailing pathophysiological mechanisms implicated in abnormal coronary reactivity resulting from mental health conditions...

The protein kinase C (PKC) and closely related protein kinase N (PKN) families of serine/threonine protein kinases play crucial cellular roles. Both kinases belong to the AGC subfamily of protein kinases that also include the cAMP dependent protein kinase (PKA), protein kinase B (PKB/AKT), protein kinase G (PKG) and the ribosomal protein S6 kinase (S6K). Involvement of PKC family members in heart disease has been well documented over the years, as their activity and levels are mis-regulated in several pathological heart conditions, such as ischemia, diabetic cardiomyopathy, as well as hypertrophic or dilated cardiomyopathy...

PURPOSE: Dynamic contrast enhanced MRI of the heart typically acquires 2-4 short-axis (SA) slices to detect and characterize coronary artery disease. This acquisition scheme is limited by incomplete coverage of the left ventricle. We studied the feasibility of using radial simultaneous multi-slice (SMS) technique to achieve SA, 2-chamber and/or 4-chamber long-axis (2CH LA and/or 4CH LA) coverage with and without electrocardiography (ECG) gating using a motion-robust reconstruction framework...

BACKGROUND: Over the past several years, a variety of human and animal studies have shown that circadian clocks regulate biological cardiovascular rhythms in both health and disease. For example, heart rate and blood pressure fluctuate over 24-hour daily periods, such that levels are higher in the morning and progressively decline in the evening. METHODS AND RESULTS: It is interesting to note that the timing of the administration of various cardiac treatments can also benefit some cardiovascular outcomes...

There are limited contemporary data on readmission after revascularization for chronic mesenteric ischemia (CMI). This study aimed to determine the rates, reasons, predictors, and costs of 30-day readmission after endovascular or surgical revascularization for CMI. Patients with CMI discharged after endovascular or surgical revascularization during 2013 to 2014 were identified from the Nationwide Readmissions Database. The rates, reasons, length of stay, and costs of 30-day all-cause, non-elective, readmission were determined using weighted national estimates...

BACKGROUND: Fetal origin of adult cardiovascular disease is one of the most pressing public concerns and economic problem in modern life. Maternal cigarette smoking/nicotine abuse increases the risk of cardiovascular disease in offspring. However, the underlying mechanisms and theranostics remain unclear. We hypothesized that fetal and neonatal nicotine exposure enhances microRNA-181a (miR-181a) which targets large-conductance Ca2+ -activated K+ (BKCa ) channels, resulting in increased coronary vascular tone in adult offspring...

Diabetics have higher morbidity and mortality in cardiovascular disease (CVD). A variety of anti-diabetic agents are available for clinical choice. Cardiovascular (CV) safety assessment of these agents is crucial in addition to hypoglycemic effect before clinical prescription. Adenosine 5'-monophosphate-activated protein kinase (AMPK) is an important cell energy sensor, which plays an important role in regulating myocardial energy metabolism, reducing ischemia and ischemia/reperfusion (I/R) injury, improving heart failure (HF) and ventricular remodeling, ameliorating vascular endothelial dysfunction, anti-chronic inflammation, anti-apoptosis and regulating autophagy...

Background: Atherosclerosis is a major cardiovascular disease that causes ischemia of the heart, brain, or extremities, and can lead to infarction. The hypolipidemic agent atorvastatin calcium (Ato) alleviates atherosclerosis by reducing plasma lipid and inflammatory factors. However, the low bioavailability of Ato limits its widespread use and clinical effectiveness. Curcumin (Cur), a natural polyphenol with antioxidation and anti-inflammation bioactivities, has potential anti-atherosclerosis activity and may reduce Ato-induced cytotoxicity...

Heart disease is the leading cause of death worldwide. A key pathogenic factor in the development of lethal heart failure is loss of terminally differentiated cardiomyocytes. However, mechanisms of cardiomyocyte death remain unclear. Here, we discovered and demonstrated that ferroptosis, a programmed iron-dependent cell death, as a mechanism in murine models of doxorubicin (DOX)- and ischemia/reperfusion (I/R)-induced cardiomyopathy. In canonical apoptosis and/or necroptosis-defective Ripk3 -/- , Mlkl -/- , or Fadd -/- Mlkl -/- mice, DOX-treated cardiomyocytes showed features of typical ferroptotic cell death...

Nilotinib, a second-generation tyrosine kinase inhibitor, is considered as one of the most effective drugs for the treatment of chronic myeloid leukemia (CML); however, the use of nilotinib has been reported to be associated with vascular adverse events, such as peripheral arterial occlusive disease and ischemic heart disease. Moreover, there are few reports on cerebral vascular disease associated with nilotinib use. We herein describe the case of a 55-year-old male patient with CML, who presented with cerebral infarction and severe cerebrovascular stenosis that developed during nilotinib treatment...
