Heart Disease in African Americans Stacy Johnson HCS 245 June 14‚ 2012 Margaret Latham Heart Disease in African Americans Heart disease‚ technically known as cardiovascular disease (CVD)‚ is the number one killer of African Americans. Cardiovascular disease is the narrowing of arteries due to the build-up of atherosclerosis‚ or plaque‚ in the walls of arteries (Heart.org). This narrowing of the blood vessels and arteries causes the blockage of oxygen and blood supply needed for proper function

the number of deaths from heart disease approximately equals to the number of deaths from cancer‚ chronic lung disease‚ pneumonia and influenza‚ and others combined. One of the symptoms of coronary disease is angina pectoris. Unfortunately‚ a lot of people do not take it seriously‚ and thus not realizing that it may lead to other complications‚ and even death. The Human Heart In order to understand angina‚ one must know about our own heart. The human heart is a powerful muscle in the

Coronary heart disease Heart disease is leading cause of the death in the United States for both men and woman. (NIH‚ 2016) In 2014 614‚348 deaths were reported to be caused by heart disease. (Centers for Disease Control and Prevention‚ 2015) Approximately 14 million people experience coronary artery disease and it is responsible for 20 percent of all US deaths. (F Brian Boudi‚ 2016) Statistics shows that men are more likely to experience CAD than women. (F Brian Boudi‚ 2016) The center for Disease

Introduction In this lab‚ I looked at how exercise affects a person’s heart rate (BPM)‚ systolic pressure‚ diastolic pressure‚ and Mean Arterial Pressure (MAP). Heart rate is measured by beats per minute while systolic and diastolic pressure are measured by millimeters of Mercury. I found the MAP by the following equation‚ MAP= Diastolic Pressure + ⅓(Systolic-Diastolic). We found out that heart rate and systolic pressure were highest right after and during exercise‚ while diastolic pressure and

TITLE: Effect of the caffeine on the heart rate OBJECTIVE: To investigate the effect of the caffeine on the heart rate of living organisms. INTRODUCTION: * Daphnia Daphnia are small‚ planktonic crustaceans‚ between 0.2 and 5 mm in length. Daphnia are members of the order Cladocera‚ and are one of the several small aquatic crustaceans commonly called water fleas because of their saltatory swimming style (although fleas are insects and thus only very distantly related). They

OF THE HEART Anatomy: The heart and heart wall layers: The heart is located in the left side of the mediastinum; it consists of three muscle layers the Endocardium‚ myocardium‚ and epicardium. The epicardium is the outermost layer of the heart. The myocardium is the idle layer of and actual contracting muscle of the heart. The endocardium is the innermost layer and lines the inner chambers and heart valves. Pericardial sac: The pericardial sac encases and protects the heart from trauma

Prevention of Heart disease Heart disease is very serious issue that can affect many Americans everyday. In the United States‚ more than 60 million Americans have some form of cardiovascular disease. About 2600 people die everyday of cardiovascular disease. Cancer‚ the second largest killer‚ accounts for only half as many deaths. Cardiovascular disease can take many forms‚ including high blood pressure‚ coronary artery disease‚ valvular heart disease‚ stroke‚ or rheumatic fever/rheumatic heart disease

Cardiomyopathy also known as the “heart muscle disease” is a deterioration of the function of the myocardium. This sometimes leads to heart failure. People with this disease are often at risk of dangerous forms of irregular heartbeat and sudden cardiac death. The term cardiomyopathy generally apply’s to any disease affecting the heart. Usually it is used for severe myocardial disease leading to heart failure. Different cases of myocardial diseases can be categorized as extrinsic or intrinsic. The

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 is a progressive disease that starts in childhood. For some people the disease quickly

issues of heart disease. Truly‚ bringing awareness to the underlying causative factors of heart disease is very important in a society‚ as we are seeing heart disease manifesting in people of all ages and people of all ethnic backgrounds. Equally important is bringing awareness to ways of preventing or decreasing heart disease in the United States. A few years back‚ heart disease was thought to be more prevalent in the older population within the society. Unfortunately‚ today heart disease is
