Metoprolol Metoprolol is a beta-Adrenergic blocking agent. Beta receptors are part of the sympathetic nervous system and are found on cells of the heart‚ smooth muscles‚ in airways‚ arteries and kidneys. Associated with stress response‚ they are stimulated by epinephrine. Beta blockers interfere with the binding of epinephrine at the receptors. Metoprolol works by inhibiting the response to adrenergic stimuli by blocking beta one adrenergic receptors within the myocardium. (Hoffman‚ Jones

Scientific Basis Congestive Heart Failure is a disease in which the heart is unable to properly keep up with the amount of blood being sent to the heart. The heart muscle itself‚ in the case of heart failure‚ is unable to sufficiently pump the blood away from the heart and to the body to keep up with the incoming deoxygenated flow. This failure to pump blood can build up pressure and cause additional pumping resistance. The decreased cardiac output of heart failure causes the circulation to become

Human ECG Abstract The purpose of these lab exercises is to understand the function and importance of an electrocardiogram. This lab will demonstrate how stress levels or different elevations can affect human heart rate. Furthermore‚ the equipment used in the experiment will show the functions in the right and left arm; as well as‚ in the right and left ankles. Finally‚ the lab will serve a purpose as a way to know how to read an electrocardiogram and calculate the heart rate. Introduction

Background Atherosclerotic plaques that result in acute coronary syndromes often occur at sites with coronary artery stenosis. The risk factors for developing these plaques and events at this point poorly understood. Methods In a prospective study‚ 697 patients with acute coronary syndromes underwent three-vessel coronary angiography and gray-scale and radiofrequency intravascular ultrasonographic imaging after percutaneous coronary intervention. Subsequent major adverse cardiovascular

Introduction The major function of the heart is to force blood in to a closed system of blood vessels within which the blood is confines and circulated to the entire body. Heart’s activity can be compared to a muscular pump equipped with one way valves. With each heartbeat‚ an electrical impulse travels through the heart and causes the heart muscle to squeeze and pump blood from the heart. These electrical impulses‚ transmitted through the heart‚ are spread throughout the body. This electrical

CAD is thought to begin with damage or injury to the intimal layer of coronary artery‚ sometimes as early as childhood. The damage may be caused by various factors‚ including: smoking‚ hypertension‚ hypercholestromia‚ diabetes or insulin resistance‚ radiation therapy to the chest‚ as used for certain types of cancer‚ and sedentary lifestyle. Once the intimal layer of coronary artery is damaged‚ fatty deposits (plaques) made up of cholesterol and other cellular waste products tend to accumulate at

Atherosclerosis‚ also known as the hardening of arteries‚ is a condition where plaque builds up in the arteries. The plaque builds up inside the arteries and either partially or completely blocks the blood flow. Diseases like coronary heart disease angina‚ and chronic kidney disease can occur as a result of atherosclerosis. When atherosclerosis affects the arteries in the heart‚ it is known as a coronary heart disease‚ and coronary heart disease is the number one killers of Americans. Atherosclerosis

Chronic Disease Outline for Cardiovascular Disease Introduction – The statistics for cardiovascular disease are astonishing‚ approximately 26.5 million people are diagnosed with one form or another of heart disease each year. Of those that are diagnosed approximately 600‚000 lose the battle each year. Many live their lives with some form of heart disease and may not even know it. Cardiovascular disease which is also known as heart disease can come in all forms from an irregular heart beat to heart
