Causes Of Coronary Heart Disease

According to the National Heart, Lung and Blood Institute (NHLBI), Coronary heart disease is a cardiovascular disease caused by a cholesterol substance termed plaque, accumulating within the coronary arteries, which is where oxygen-rich blood is delivered to the heart. Progressively, the flow of oxygen to the heart will suffer if hardened plaque begins to narrow the coronary arteries. Furthermore, blood clots could occur upon the surface of plaque if it ruptures. Large blood clots will incapacitate blood flow through the coronary arteries. As a result, angina or a heart attack may follow plaque-blocked oxygen-rich blood flow. The NHLBI refers to CHD as a progressive disease where a destabilised heart can lead to conditions such as heart failure

Have you ever imagine a body functioning without a heart? The heart, the center of the cardiovascular system, is the essential manager for just about everything that gives the body life. Correspondingly, most of the heart diseases are fatal and cannot be ignored. In fact, "heart disease is the leading cause of death for women as well as men"(1). According to the Centers for Disease Control and Prevention, every 25 seconds someone has a coronary event(1). One of these diseases is coronary heart disease (CHD). "CHD is a condition in which certain substances builds up inside the coronary arteries"(2). When these substances block the flow of oxygen-rich blood, heart attacks most often occur. Heart attack, also known as myocardial infarction, is a serious event and a leading killer that has numerous symptoms and certain risk factors.

Coronary artery disease affects the circulatory system. Chemically, this disease develops when blood vessels that are necessary for living become badly damaged. Cholesterol plaques become inflamed in the arteries. The most common signs and symptoms are chest pains which tighten the chest as if someone were standing on it. Shortening of breath also affects those with this disease because the heart is unable to supply enough blood. A major sign of this disease is having a heart attack. This indicates an artery that is completely blocked. This disease is caused by damaging the coronary arteries by smoking, diabetes, high blood pressure or high cholesterol. To diagnose this disease, medical physicians will perform physical exams and examine blood

Coronary heart disease: Coronary heart disease is the build-up of plaque such as cholesterol and other fatty substances within the coronary arteries causing a reduced or no supply of oxygen to the heart. The process of plaque lining the coronary arteries is called arteriosclerosis. Coronary heart disease can be caused and triggered by many different factors. These

Similar to other diseases coronary heart disease affects thousands of people. The disease affects the heart in that it causes a waxy substance called plaque where it builds up inside of the coronary arteries. These arteries supply oxygen-rich blood to the heart muscle. When a person has coronary heart disease the hardened arteries restrict blood flow, which means that the heart cannot receive enough oxygenated blood, especially when it beats quickly during physical exertion or stress. This can cause chest pain and shortness of breath. However, if the artery is completely blocked, a heart attack can occur. Lack of oxygen during a heart attack causes damage as the heart muscle dies and is replaced with scar tissue. If damage is severe, the heart

There are many known risk factors that have been shown to correlate with heart disease. High blood pressure, smoking, diabetes, lack of physical activity, and obesity, are all risk factors that correlation to and increase risk of CVD. Fortunately, all of these risk factors can be managed and controlled through a variety of ways. Although CVD is mostly preventable, cardiovascular disease remains as one of the leading causes of death in the United States (Erhardt, 2009).

Coronary Heart Disease (CHD) is when blood flow to the heart is temporarily or permanently blocked. This is problematic to the wellbeing of one’s heart, because blood transports the materials (nutrients, minerals, oxygen) that are required for heart muscles (or any muscle) to contract and sustain the life of those cells. Caption #1 shows the muscles in the heart that are affected by CHD. Coronary Heart Disease can be caused by the buildup of plaque (cholesterol) in the arteries which direct blood to the heart, and by the increase in blood pressure.

Coronary disease is the leading cause of death in the United States. According to Centers for Disease Control and Prevention (CDC) 796,494 men and women between the age of (<) 1yr to 85 and older expired due to major cardiovascular disease (Deaths: Final Data for 2013, table 10, 2015) . This disease has a natural cradle-to-grave course of action that may consist of “susceptibility, presymptomatic disease, clinical disease, recovery disable and/or death” (Mills, 2015).

In the case of CHD, one study has characterized the majority of very susceptible individuals as being the ones who have issues with several of the following risk factors: elevated low-density lipoprotein cholesterol levels, stress, lack of meaningful physical activity, being overweight, high blood-sugar levels, and high blood pressure (Castelli, 1984). Further, it is important to note that interventional trials have determined that; although decreasing a risk factor typically lowers the incidence rate of CHD, caution must be exercised in risk management to avoid exasperating one risk by while managing another (Castelli, 1984), which may be challenging due to the number of interrelated contributing risks.

The risk factors of heart attacks are a leading killer of both men and women in the United States. “Heart disease is the leading cause of death in both men and women, and more than 900,000 Americans experience a heart attack every year” (Damlo, 2007, p. 1096-1101). According to the American Heart Association, “heart attack is a sudden and sometimes fatal occurrence of coronary

Heart disease has many symptoms like pressure in the chest or heartburn and pain in the

1. Coronary heart disease is a condition when a plaque is formed in a coronary artery. The plaque stuck in the coronary artery can narrow the artery and therefore the oxygen-rich blood flow is reduced. In another case, the plaque can break open and a blood clot can be formed which blocks the artery and prevents the supply the heart with oxygen rich blood. In such situation a heart attack may occur. Coronary Heart Disease is usually caused by poor eating habits and lack of exercise.

Usually, chest pain is the main symptom for CHD , heart attack , and heart failure.

Coronary Artery Disease is a condition where the blood flow through the coronary arteries of the heart become partially or completely blocked by plaque buildup. CAD is responsible for over 500,000 deaths in the USA annually. Unfortunately in ¼ of the population, death is the first warning sign of CAD. Atherosclerosis is the process by which plaque builds up in the vessels that supply blood and oxygen to the heart muscle. This lack of blood flow is called ischemia, which will lead to angina in many cases. Angina is caused by a lack of perfusion of the myocardium. CAD is a disease that is developed over time due to unchanged risk factors such as obesity, sedentary lifestyle, hyperlipidemia , cigarette smoking, and hyperlipidemia. The severity of Coronary Artery Disease can be managed through lifestyle changes and medication. If the disease has advanced beyond natural repair by lifestyle modifications, surgery may be the next option. Coronary Artery Bypass Graft (CABG) surgery or placement of cardiac stents are the two most common forms of surgery to fix CAD. These surgeries are not a substitute for lifestyle modifications, but may help those with severe CAD begin to make lifestyle changes without symptoms arising at low intensity exercises.

Cardiovascular disease is a terminology referring to strokes, coronary heart disease and heart failure. Salt is a major factor that increases the patient’s blood pressure and is therefore responsible for many heart attacks and strokes every year. Symptoms can include chest pain, shortness of breath, pain and numbness in your legs and arms if the blood vessels in those parts of the body are narrowed (less blood flowing through), pain in the neck, jaw, throat and upper abdomen or back.
