Three Layers Of Ischemic Heart Disease

Whether it is arteriosclerosis, congestive heart failure, broken heart syndrome, coronary microvasculature disease, or coronary heart disease, the National Institute of Health reports that "heart disease is the number one killer in the U.S.[and] also a major cause of disability." The good news is that there are things that can be done to lessen the chance of having a heart disease-related incident.

Cardiovascular disease has reportedly been the number one disease killer for men and women in the United States of America. Every one out of four deaths is caused by heart disease in the United States alone (Centers for Diseases Control and Prevention). Heart disease refers to the different types of conditions and symptoms that can affect the one’s heart and its functions to the body (Mayo Clinic). Cardiovascular/Heart disease has many causes and conditions, prevention methods and symptoms, and treatment options.

The most common heart disease that most people have is coronary artery disease. Coronary artery disease tends to cause heart attacks. When a substance of plaque builds up in your arteries, heart disease may occur. When plaque builds up, a person’s arteries can narrow over time, limiting blood flow to the heart. This could also block the blood flow. This process is called

Blood vessels start to develop during the embryonic stage and continue through the life span. There are more than 66,000 miles of vessels carrying blood through the body. Blood vessels consist of arteries, capillaries, and veins. The walls of the arteries and veins consist of three separate layers called the tunica externa (adventitia), tunica media, and the tunica intima. As blood vessels decrease in diameter the thickness of the walls also decrease.

Heart disease affects people all around the world. Many life habits can lead you to potentially having a heart disease, but it can also be inherited. About 610,000 people die of heart disease in the United States every year. It is the leading cause of death for both men and women. These case studies show that heart problems can strike you at any moment, even when you’re least expecting it.

The abdominal aorta consists of three distinct tissue layers including: the intima, media, and adventicia. There is

It is not only the leading cause of death in the United States, but also it is the most common type of heart diseases. By killing nearly 380,000 people yearly, and that is about every 60 seconds someone dies from it. Yes, it is the heart attack or also known as coronary heart disease. Heart attacks occur when one of the coronary artery is blocked or narrowed by fats. After that, the blood clot will gather and block the narrowed artery causing a slowly painful death to the artery by decreasing the amount of oxygen, and replacing the live tissue with a dead one.

Heart Disease, also known as Cardiovascular Disease is abnormal function of the heart or blood vessels. There are many different types of heart disease. “Heart Disease” is just a word that describes the many other conditions and diseases there is that can affect our heart. The causes of heart disease are stressing, eating too much fatty foods, stressing, drinking a lot of alcohol, and not being active. Coronary Heart Disease is the leading heart disease in the United States. Coronary arties surround the heart and provides the heart with the energy and oxygen it needs (Lehnardt, 2016). Almost 2,500 Americans die before they can get to the hospital. You can prevent heart disease.

“Ischaemic Heart disease is often termed coronary artery disease or coronary heart disease” [I]. This is because it takes a long period of time, decades of quiet, slowly progressive coronary atherosclerosis

Perhaps the most deadly of all the heart’s complications is a heart attack. A heart attack is the leading killer in men and women in the United States, with an estimate 1 million heart attacks alone in the United States (NHLBI). A heart attack occurs when the heart is unable to obtain oxygen, due to a section of heart muscle becoming blocked and preventing oxygen-rich blood to flow properly. The leading cause of heart attacks is coronary heart disease, also known as coronary artery disease. Coronary heart disease is a result of plague, a waxy like substance, building up inside the coronary arteries, the arteries that are responsible for providing blood to the heart (NHLBI). Overtime, the built up plaque can rupture inside of an artery causing a blood clot to form, which prevents blood from reaching heart muscles. Portions of heart muscle once fed by this now blocked artery begin to die if blockage is not treated in time.

Heart disease is often regarded as a problem that most people are born with or something that only happens in older adults; and also can happen to anyone. In fact, according to Medline, heart disease is the most common cause of death in the United States. The majority of cardiovascular disease (CVD) is caused by risk factors that are controllable and uncontrollable.

Complications that can also cause myocardial ischemia are heart attacks, arrhythmia , and heart failure. For a patient that has had any of these complications before are at a hirer risk for developing myocardial ischemia. Risk factors would be previous heart attacks, hypertension , high blood cholesterol, smoking, obesity, lack of physical activity, diabetes, and drug and alcohol abuse. In order to prevent or lower the risk of having myocardial ischemia is to make life-style changes for the better. It is also important to never and try to diagnose one’s self and to contact your doctor’s office if you may have any concerns.

Heart disease includes numerous problems, many of which are related to a process called atherosclerosis. Atherosclerosis is a condition that develops when plaque builds up in the walls of your arteries. This plaque buildup narrows the arteries, making it harder for your blood to flow. Heart disease describes a lot of conditions that affect your heart. One that affected my family is stroke. My great grandmother had a stroke which paralyzed her. A stroke happens when the blood flowing to part of your brain is suddenly interrupted or reduced, depriving the brain of oxygen causing brain cells to die. There are many risk factors that can cause a stroke for example having high blood pressure, smoking cigarettes, high cholesterol, diabetes, and sleep apnea.

The three layers of the blood vessels are tunica intima, tunica media and tunica adventitia. The tunica intima in the inner most layer of blood vessel, consists of endothelium and delicate connective tissue basement membrane. The internal elastic membrane separates the tunica intima from blood vessels middle layer. Middle layer is called tunica media. It consists of smooth muscle cells circularly arranged around the blood vessel. The amount of blood flowing through a blood vessel can be regulated by contraction or relaxation of the smooth muscle in the tunica media. A decrease in blood vessel diameter caused by smooth muscle contraction. An increase in blood vessel diameter resulting from smooth muscle relaxation. This layer also contains

It was reasoned that epicardially-derived cells grow to form multiple strands within the subepicardial space (Ando et al., 2004; Bogers et al., 1989). This primary vascular plexus subsequently expands into the heart in an epi-to-endocardial direction. Through coronary angiogenesis, capillaries sprout towards the heart base eventually connecting to the aorta. The endothelial strands can be found at all three sinuses but later decrease in number until only two channels persist and acquire a muscular coat to form the proximal segments of the left and right coronary arteries (Ando et al., 2004; Tomanek, 1996). Correct placement of the coronary arteries at the aortic valvar sinuses is facilitated by a brief dissociation from the aortic wall before there is penetration of the aortic root (Ando et al., 2004).
