The relationship between the heart and the brain is complex and integral in the maintenance of normal cardiovascular function. Certain pathological conditions can interfere with the normal brain-heart regulatory mechanisms and result in impaired cardiovascular function. The mechanisms through which the central and autonomic nervous systems regulate the heart and the manner in which their impair...

Oxidative stress plays an important role in the development of diabetic cardiomyopathy. In the present study, we determined whether the effect of astragalus polysaccharides (APS) on diabetic cardiomyopathy was associated with its impact on oxidative stress. Streptozotocin (STZ)-induced diabetic mice and heterozygous superoxide dismutase (SOD2+/-) knockout mice were administered APS. The hemodyn...

broken heart classically refers to an emotional state caused by psychological pain. Current research indicates that a broken heart is a true medical condition, not just a play on words. Broken heart syndrome is due to an exaggerated sympathetic response to stress that causes a severe but reversible left ventricular failure. Takotsubo cardiomyopathy is a reversible left ventricular dysfunction t...

Takotsubo cardiomyopathy mimics acute coronary syndrome and is accompanied by reversible left ventricular apical ballooning in the absence of angiographically significant coronary artery stenosis. In Japanese, "takotsubo" means "fishing pot for trapping octopus," and the left ventricle of a patient diagnosed with this condition resembles that shape. Takotsubo cardiomyopathy, which is transient ...

Pulmonary arterial hypertension is a fatal disease. Intravenous prostanoids are often utilized for long-term management of patients. The therapy requires a significant commitment and change in lifestyle for both the patient and family. Takotsubo cardiomyopathy, transient apical ballooning syndrome, has been reported in association with emotional and physical stress. This case report describes a...

Cardiac failure is the most prevalent cause of death at higher age, and is commonly associated with impaired energy homeostasis in the heart. Mitochondrial metabolism appears critical to sustain cardiac function to counteract aging. In this study, we generated mice transgenically over-expressing the mitochondrial protein frataxin, which promotes mitochondrial energy conversion by controlling ir...

OBJECTIVES Stress cardiomyopathy is a cardiac syndrome that is characterized by transient left ventricular systolic dysfunction in the absence of obstructive coronary artery disease. Its epidemiology has been described in homogeneous Asian, Caucasian and Black populations, but its characteristics in heterogeneous populations are poorly understood. Our aim was to assess the characteristics of st...

Takotsubo cardiomyopathy, also known as apical ballooning syndrome, stress cardiomyopathy, or broken heart syndrome, is a disease characterized by transient ventricular dysfunction in the absence of obstructive coronary artery disease. Herein, we present a case in which a heart with mild takotsubo cardiomyopathy was utilized as the donor organ for an orthotopic heart transplant.

Stress-induced cardiomyopathy is characterized by transient left ventricular dysfunction, usually followed by complete resolution. It is precipitated by severe stress, and the most common variant (takotsubo) is marked by apical hypokinesis and ballooning with basal hyperkinesis. Serotonin syndrome is best understood as excess serotonergic activity in the central and peripheral nervous system. T...

Diabetic cardiomyopathy (DCM) is a serious complication of diabetes caused by oxidative stress, inflammation, insulin resistance, myocardial fibrosis, and lipotoxicity; its nature insidious, complex difficult to treat. NLRP3 inflammasome triggers the maturation release pro-inflammatory cytokines, participates in pathophysiological processes such as resistance addition being closely related deve...
