arteries‚ causing a decreased blood supply to the myocardial layer of the heart‚ and prevents the arteries from dilating. As a result the tissue is deprived of oxygen necessary to thrive‚ which in turn can lead to myocardial ischemia‚ leading to several types of infarctions. Depending on the area of the ischemia‚ there can be several complications. For example‚ a ST segment elevation myocardial infarction (STEMI) occurs when there is a myocardial insufficiency caused by an occlusion that has completely

He demonstrated that‚ by blocking the cardiac beta-receptors‚ these agents could cause inhibitory effects on the sinus node (chronotropic effect)‚ atrioventricular node (dromotropic effect)‚ and on myocardial contractility (inotropic effect).1 It is important to note that not all beta receptors (β-receptors) are the same. There are two clinically targeted types of beta receptors in the human body: beta 1 (β1) receptors which are mostly located on the
