Background- The prevalence of ischemia and its prediction of events are unclear in outpatients with diabetes mellitus in the modern era of intensive medical management. We sought to identify the prevalence of ischemia, subsequent cardiac events, and impact of sex, stress type, and symptom status on these findings in a cohort of stable outpatients with diabetes mellitus referred for single-photo...

Mesenteric ischemia after cardiac surgery is rare but dramatic. We present a patient who had acute mesenteric ischemia following low cardiac output after coronary artery bypass grafting. Our patient was successfully treated with continuous intra-arterial perfusion with papaverine. We think that selective angiography must be performed as early as mesenteric ischemia is suspected, to get earlier ...

It is estimated that by 2035, more than 130 million adults will suffer from various types of cardiovascular diseases. Therefore, it is very important to know the pathogens of cardiac diseases and investigate new treatments. Also, despite continuous progress in diagnosis, patient education, and risk factor management, myocardial infarction (MI) remains one of the most common causes of morbidity,...

RATIONALE G protein-coupled receptor kinase 2 (GRK2) is an important molecule upregulated after myocardial injury and during heart failure. Myocyte-specific GRK2 loss before and after myocardial ischemic injury improves cardiac function and remodeling. The cardiac fibroblast plays an important role in the repair and remodeling events after cardiac ischemia; the importance of GRK2 in these event...

Acute regional ischemia in the heart can lead to cardiac arrhythmias such as ventricular fibrillation (VF), which in turn compromise cardiac output and result in secondary global cardiac ischemia. The secondary ischemia may influence the underlying arrhythmia mechanism. A recent clinical study documents the effect of global cardiac ischaemia on the mechanisms of VF. During 150 seconds of global...

Abstract Coronary heart disease leading to myocardial ischemia is a major cause of failure. A hallmark failure fibrosis. Using murine model ischemia/reperfusion injury (IRI), we showed that, following IRI, in mice genetically deficient the central factor complement system, C3, necrosis was reduced compared with WT mice. Four weeks after ischemic period, C3 −/−mice had significantly less cardiac...

OBJECTIVES The major aim of this study is to test the hypothesis that stress cardiac magnetic resonance (CMR) imaging can provide robust prognostic value in women presenting with suspected ischemia, to the same extent as in men. BACKGROUND Compelling evidence indicates that women with coronary artery disease (CAD) experience worse outcomes than men owing to a lack of early diagnosis and manag...

Temporary epicardial pacing wires (TEPWs) are commonly used during cardiac surgery to meet unforeseen complications like heart blocks or asystole. These are generally considered to be safe. The incidence of major complications with their use is low, but could be life threatening. Complications can be divided into those encountered during placement, removal, or retention of temporary epicardial ...

Acute kidney failure was produced in the anesthetized rat by 1 h of complete renal artery occlusion. Kidney function was studied either immediately after release of the occlusion or 1 day later using clearance, micropuncture, histological, and nephron dissection techniques. Polyfructosan clearance was decreased to 5% of normal after temporary occlusion. Proximal tubular pressure (PTP) averaged ...

The incidence of ischemic heart disease (IHD) is increasing worldwide. number patients with IHD or without interventions coming for non-cardiac surgical procedures are increasing. These have an increased risk myocardial ischemia, infarction (MI), conduction disturbances, morbidity, and mortality during the peri-operative period.
