Copeptin is a non-specific marker of an endogenous stress response. A dual biomarker marker approach involving the simultaneous use of troponin and copeptin assays may assist early exclusion of acute coronary syndrome in Australian emergency departments. The utility and limitations of this approach are discussed.

Mental stress-induced (MSIMI) or physical stress-induced (PSIMI) myocardial ischemia portends a worse prognosis in patients with coronary artery disease (CAD). Vitamin D insufficiency is associated with adverse cardiovascular outcomes, but its relationship to myocardial ischemia remains unclear. We hypothesized that vitamin D insufficiency will be associated with a higher prevalence ...

Microvascular angina (MVA) is characterized by anginal chest pain, an abnormal stress test, and normal coronary arteries on coronary angiography. Although the exact pathogenesis remains unclear, endothelial dysfunction is a contributing factor. To date, there exists no specific therapy for this disease. Phosphodiesterase-5 inhibitor improves the endothelial function and subsequently ...

Ischemic preconditioning (PC) is an adaptive response to transient myocardial ischemia that protects the heart from subsequent ischemia/reperfusion (I/R) injury. However, the mechanisms underlying its cardioprotective effects remain unclear. Myocardium of adult male C57/BL6 mice, preconditioned by 6cycles of 4minute coronary occlusion and reperfusion, showed nuclear translocation of ATF3, and ...

The protective role of etanercept in myocardial ischemia/reperfusion is not well understood. The aim of this study was to investigate whether etanercept modulates neutrophil accumulation, TNF-α induction and oxidative stress in an ischemia/reperfusion injured rat heart model. Rats were randomly exposed to sham operation, myocardial ischemia/reperfusion (MI/R) alone, MI/R+ etanercept. ...

The pathophysiological basis of heart failure is cardiac remodeling, a process that comprises structural and functional changes including cardiomyocyte proliferation, hypertrophy, necrosis, apoptosis, autophagy, interstitial fibrosis, contractile dysfunction and ventricular dilatation. Accumulating evidence demonstrate that tumor necrosis factor-like weak inducer of apoptosis (TWEAK) is involved in the process by binding ...

Introduction. The incidence of venous infarction after surgical resection of meningioma is low, but its occurrence can necessitate additional surgical procedures and long hospital stay. In this study, we evaluated variables associated with venous infarction after meningioma surgery. Methods. Among 825 patients with intracranial meningiomas who underwent microsurgical resection between ...

Paragangliomas, extra-adrenal pheochromocytomas, are rare and classically associated with sustained or paroxysmal hypertension, headache, perspiration, palpitations, and anxiety. A 49-year-old male, parachute instructor, likely developed a hypertensive emergency when deploying his parachute leading to a myocardial infarction. A para-aortic tumor was incidentally discovered during the patient's emergency department work-up and ...

Background. The discovery of a large left atrial mass through echocardiography obliges the clinician to perform a differential diagnosis to distinguish tumor from thrombus. The neovascularization of the mass could be helpful to predict the type of the malformation and whether it is in favour of a vacular tumour rather ...

Papillary fibroelastomas of the heart valves are benign, slow-growing, rare tumors of the heart. This tumor represents a potential cause of systemic embolism, stroke, myocardial infarction and sudden death. Early diagnosis is very important, as surgical excision of these tumors can prevent cerebrovascular and cardiovascular complications. Diagnosis is usually made ...

Background: Cardiac pheochromocytoma is extremely rare. Previous papers usually are reports of a single case. Transthoracic echocardiography (TTE) offers a useful option, but the features of cardiac pheochromocytoma on TTE have not been favorably reported. In this study, the findings of cardiac pheochromocytoma on TTE in nine cases were presented. ...

Melanoma has a known propensity for cardiac metastasis. Most cases are associated with widespread metastatic disease and multiple sites of cardiac involvement and are not appropriate for surgical resection. When there is an isolated metastasis to the heart, the melanoma tends to involve the right heart. Rarely does melanoma metastasize ...

Papillary fibroelastomas are uncommon benign tumors with frond-like growths usually arising from the heart valves. The identification of their presence is of major clinical importance owing to the fact that although rarely symptomatic they can cause coronary occlusion, stroke, and even sudden cardiac death. We present an asymptomatic 38-year-old woman ...

Pre-percutaneous coronary intervention (PCI) Thrombolysis In Myocardial Infarction (TIMI) grade 3 flow has been identified as a predictor of final TIMI grade 3 flow and better survival. Yet pharmacologic strategies increasing the rates of pre-PCI TIMI grade 3 flow resulted in more bleeding, without a benefit in survival. The aim ...

The concept that atherosclerotic disease could be a form of neoplasm has been proposed in the medical literature for centuries, yet few modern cardiologists or pathologists describe atherosclerotic plaques as having the appearance of tumors. Although atherosclerosis is now considered to be an inflammatory disease, parallels between the pathophysiologic courses ...
