In order to study predisposing effects of sex hormones in acute myocardial infarction and in unstable angina pectoris, serum estradiol, progesterone, testosterone, creatine phosphokinase (CPK), and lactic dehydrogenase (LDH) levels were measured in 26 male patients with acute myocardial infarction,
Day-of-admission sera from myocardial infarction patients (MI) and patients with cardiopathies other than MI (non-MI) were analysed for total and unbound cortisol (F), progesterone (P4), oestrone (E1), and corticosteroid binding activities (CBG). The MI who survived (n = 28) showed high increases of
Recent data from the Women's Health Initiative have highlighted many fundamental issues about the utility and safety of long-term estrogen use in women. Current hormone replacement therapy for postmenopausal women incorporates progestin with estrogen, but it is uncertain if combined therapy provides
The levels of serum estradiol, testosterone and progesterone were determined in 13 cases of acute myocardial infarction. Thirteen intensive care patients without coronary, hepatic or renal disease, 13 cases of unstable angina and 15 normal subjects. The patients were males ranging from 24 to 56
OBJECTIVE
We compare the effects of postinjury administration of allopregnanolone, a metabolite of progesterone, to progesterone in an animal model of transient middle cerebral artery occlusion.
METHODS
Focal cerebral ischemia was induced in age-matched, adult, male, Sprague-Dawley rats by using an
We evaluated the neuroprotective effects of delayed progesterone (PROG) treatment against ischemic stroke-induced neuronal death, inflammation, and functional deficits. We induced transient focal cerebral ischemia in male rats and administered PROG (8 mg/kg) or vehicle intraperitoneally at 3, 6, or
Recent experimental evidence indicates that progesterone (PROG) protects against various models of brain injury, including ischemic stroke. Most human studies of pharmacologic treatments for acute cerebral stroke have failed despite initial success in animal models. To simulate better the typical
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
All combination hormone replacement regimens contain estrogen and a progestational agent. The Women's Health Initiative trial demonstrated that taking the combination of conjugated estrogen and medroxyprogesterone resulted in a higher risk of myocardial infarction and stroke in the study population.

Progesterone has been shown to be cerebroprotective in different experimental models of brain injuries and neurodegenerative diseases. The preclinical data provided great hope for its use in humans. The failure of Phase 3 clinical trials to demonstrate the cerebroprotective efficiency of
Allopregnanolone is a neurosteroid synthesized from progesterone in brain. It increases inhibition through modulation of the gamma-aminobutyric acid type A (GABA-A) receptor. Both agents are putative neuroprotectants after ischemic stroke. We sought to confirm their effectiveness in a hypertensive
Recent studies indicate that progesterone (PROG) protects against animal brain injury, including ischemic stroke, in various animal models. However, there are insufficient studies about PROG in other various groups such as ovariectomized females and aged animals. This study was designed to examine
Progesterone hormone (P4) is a promising agent against strokes because post-ischemic administration of P4 exerts neuroprotective effects in several young and aged animal models of stroke. However, in contrast to a majority of the studies using male animals, female animals remain underrepresented. In
We investigated the effect of delayed, prolonged systemic inflammation on stroke outcomes and progesterone (P4) neuroprotection in middle-aged rats. After transient middle cerebral artery occlusion/reperfusion (MCAO) surgery, rats received P4 (8 or 16 mg/kg) or vehicle injections at 2h, 6h and every
