OBJECTIVE This study was designed to examine the effects of estrogen replacement on infarct size, ventricular remodeling, and mortality after myocardial infarction (MI) in mice. BACKGROUND Observational and clinical studies suggest that the cardiovascular effects of hormone replacement therapy can

The effect of 17 beta-estradiol on the regions of ischemia and necrosis in experimental myocardial infarction was studied in the experiments on rats. The ability of the hormone to decrease the damaged area due to anti-ischemic and antinecrotic effects is found.

Relationships of plasminogen activator inhibitor activity and lipoprotein(a) with insulin, testosterone, 17 beta-estradiol, and testosterone binding globulin in myocardial infarction patients and healthy controls.

The relationships between plasminogen activator inhibitor (PAi) activity and lipoprotein(a) [Lp(a)] and insulin, testosterone, 17 beta-estradiol, and testosterone binding globulin (TEBG) were assessed in 42 myocardial infarction male patients and 74 healthy controls. Patients had higher levels of

Differential effects of sarcolemmal and mitochondrial K(ATP) channels activated by 17 beta-estradiol on reperfusion arrhythmias and infarct sizes in canine hearts.

We have demonstrated the effects of estrogen on modulation of ATP-sensitive K(+) channels; however, the subcellular location of these channels is unknown. The purpose of the present study was to investigate the role of the sarcolemmal and mitochondrial ATP-sensitive K(+) channels in a canine model

17 Beta-estradiol differentially affects left ventricular and cardiomyocyte hypertrophy following myocardial infarction and pressure overload.

BACKGROUND We have shown previously that 17beta-estradiol (E2) increases left ventricular (LV) and cardiomyocyte hypertrophy after myocardial infarction (MI). However, E2 decreases hypertrophy in pressure overload models. We hypothesized that the effect of estrogen on cardiac hypertrophy was

Contractile responses to histamine, serotonin, and angiotensin II are impaired by 17 beta-estradiol in human internal mammary arteries in vitro.

There is accumulating evidence that estrogen replacement therapy protects against the development of coronary atherosclerosis and myocardial infarction in postmenopausal women. The mechanism of this protective effect is uncertain. The purpose of the present study was to determine whether 17

Short-term estrogen reduces myocardial infarct size in oophorectomized female rabbits in a dose-dependent manner.

17 beta-estradiol, administered acutely, protects ischemic myocardium in male rabbits. In the present study we investigated the effect of short-term estrogen on myocardial infarct size in oophorectomized female rabbits. We oophorectomized 24 sexually mature New Zealand white female rabbits. Twelve

Evidence against a role of physiological concentrations of estrogen in post-myocardial infarction remodeling.

OBJECTIVE The purpose of this study was to examine whether endogenous estrogen deficiency induced by ovariectomy affects chronic left ventricular dysfunction post-myocardial infarction (MI). BACKGROUND Epidemiologic findings suggest that mortality of postmenopausal women is increased after MI, but

Cardioprotective effects of 17 beta-estradiol produced by activation ofmitochondrial ATP-sensitive K(+)Channels in canine hearts.

We have previously demonstrated the effects of estrogen on modulation of myocardial ATP-sensitive K(+)(K(ATP)) channel. Previous studies have demonstrated that activation of mitochondrial K(ATP)channel is a major contributor of ischemic cardioprotection. The purpose of the present study was to

17 Beta-estradiol stimulates expression of endothelial and inducible NO synthase in rat myocardium in-vitro and in-vivo.

OBJECTIVE NO production has been attributed to play a major role in cardiac diseases such as cardiac hypertrophy and cardiac remodeling after myocardial infarction which display significant gender-based differences. Therefore we assessed the effect of 17 beta-estradiol (E2) on estrogen receptor (ER)

17 Beta-estradiol prevents focal cerebral ischemic damages via activation of Akt and CREB in association with reduced PTEN phosphorylation in rats.

This study aimed to assess the signaling pathway of the neuroprotective action of estrogen in the cerebral ischemic injury evoked by subjecting rats to 2-h occlusion of the middle cerebral artery (MCA) followed by 24-h reperfusion. Rats received 17 beta-estradiol (1, 4 and 10 mg/kg, i.p.) 24 h

Estrogen Therapy Worsens Cardiac Function and Remodeling and Reverses the Effects of Exercise Training After Myocardial Infarction in Ovariectomized Female Rats.

There is an increase in the incidence of cardiovascular events such as myocardial infarction (MI) after menopause. However, the use of estrogen therapy (E2) remains controversial. The aim of this study was to evaluate the effects of E2, alone and combined with exercise training (ET), on cardiac

Calcifying subpopulation of bovine aortic smooth muscle cells is responsive to 17 beta-estradiol.

BACKGROUND Arterial calcification, common in atherosclerosis, is associated with an increased risk of clinical events such as myocardial infarction. We previously identified a subpopulation of bovine aortic medial cells, calcifying vascular cells (CVCs), that have osteoblastic characteristics and

Postischemic infusion of 17-beta-estradiol protects myocardial function and viability.

BACKGROUND Females demonstrate improved cardiac recovery after ischemia/reperfusion injury compared with males. Attenuation of myocardial dysfunction with preischemic estradiol suggests that estrogen may be an important mediator of this cardioprotection. However, it remains unclear whether

Natural progesterone, but not medroxyprogesterone acetate, enhances the beneficial effect of estrogen on exercise-induced myocardial ischemia in postmenopausal women.

OBJECTIVE We sought to compare the effects of estrogen/transvaginal progesterone gel with estrogen/medroxyprogesterone acetate (MPA) on exercise-induced myocardial ischemia in postmenopausal women with coronary artery disease or previous myocardial infarction, or both. BACKGROUND Estrogen therapy
