[An experimental study of the cardiovascular activity of nistranol]
Abstract:
In concentrations of > or = 10(-5) mol/liter nistranol (11 beta-nitroxy-9 alpha-hydroxy-ethynylestradiol-diacetate) demonstrated cardiac and vascular activity in vitro. It caused concentration-dependent and reversible increase of the contractile parameters of an isolated atrial appendage of rats. A three-phase effect of nistranol on a isolated rat thoracic aorta was encountered: vasodilatation-vasoconstriction-vasodilatation. Anti-ischemic and antinecrotic effects of nistranol were noted in experimental myocardial infarction.

Exercise and Cardiovascular Response
Light to moderate physical activity initiates a series of interconnected responses in the body. The heart rate modestly increases in anticipation of the workout, followed by widespread vasodilation as oxygen consumption by skeletal muscles increases. This results in decreased peripheral resistance, increased capillary blood flow, and accelerated...
Blood Studies for Cardiovascular System I: Cardiac Biomarkers
The essential diagnostic tools for detecting myocardial necrosis and monitoring individuals suspected of having acute coronary syndrome (ACS) include:
Troponins
Troponins, particularly cardiac troponins I and T, are the most precise and sensitive markers of myocardial injury. They are detectable within 4-6 hours of myocardial injury and remain...

These markers indicate stress or strain on the heart muscle:
Natriuretic Peptides (BNP)
Cardiac myocytes produce these hormones in response to ventricular stretching...
