Learning Objectives. Pathophysiology: Coronary Artery Disease (CAD); Damaged lining of coronary arteries leading to build up of lipids and WBCs - forms plaques; Narrows lumen of arteries, can lead to thrombus or emboli by Maryanne Sandberg 1. Physically active people have increased HDL levels. Open J Cardiol Heart 4/7 Dis. State the pathophysiological changes C, Fibrous plaque. Many risk factors have been associated with CAD. Like atherosclerosis in the heart (coronary) arteries, PAD is caused by the accumulation of fatty plaque in the blood vessel walls. During the past decade, our understanding of the pathophysiology of coronary artery disease (CAD) has undergone a remarkable evolution. Developmental Stages. Found inside – Page ivThe text focuses on accurate, yet underutilized, measures of subclinical atherosclerosis, notably coronary artery calcium scanning and carotid intima-media thickness measurement. Myocardial infarction. Contrary to the successful delivery of oxygenated blood to the distal regions of the body, Peripheral Artery Disease (PAD) is characterized by the narrowing of the arteries. The Modern Trends in Vascular Surgery series brings together the best, current strategies for therapeutic and clinical practices. These books contain the latest discoveries, techniques, practice and out comes in vascular surgery. These risk factors include obesity as defined by increased waist circumference, hypertension, abnormal serum lipids, and an elevated fasting blood glucose2 (see Table 41-10). Coronary artery disease (CAD) is a medical condition which involves damage to the major blood vessels that provide the heart with oxygen and nutrients. Salt intake positively correlates with elevated BP, adding volume and increasing systemic vascular resistance (SVR) to the cardiac workload. It is estimated that the genetic contribution to CAD/MI is as high as 40% to 60%. C-reactive protein (CRP), a protein produced by the liver, is a nonspecific marker of inflammation. The incidence of CAD and MI is highest among white, middle-aged men. Normally some arterial anastomoses or connections, termed collateral circulation, exist within the coronary circulation. Blood pressure ≥140/90 mm Hg* Chapter 34 Nursing Management Coronary Artery Disease and Acute Coronary Syndrome Linda Bucher and Sharmila Johnson I have witnessed the softening of the hardest of hearts by a simple smile. Reduces myocardial oxygen demand to minimize risk of tissue injury. Those with stage 1 or 2 hypertension often require more than one drug to reach therapeutic goals8 (see Table 33-7). These medications reduce (or modify) the primary material that deposits on the coronary arteries. As obesity increases, the heart grows and uses more oxygen. About one fourth of these persons die in an emergency department (ED) or before reaching a hospital. However, the study of these behaviors remains controversial and complex. B, Partial coronary artery closure with collateral circulation being established. Exercise training for those who are physically inactive decreases the risk of CAD through more efficient lipid metabolism, increased HDL production, and more efficient oxygen extraction by the working muscles, thereby decreasing the cardiac workload. • After age 65, the incidence of MI in men and women equalizes. Learn more about the important role that inflammation, which is the body's reaction to an injury, plays in the development of coronary heart disease. 34-1, D). Coronary artery disease (CAD) is a type of blood vessel disorder that is included in the general category of atherosclerosis. Metabolic syndrome is discussed in Chapter 49. • Major modifiable cardiovascular risk factors for Native Americans are tobacco use, hypertension, obesity, and diabetes mellitus. CAD is usually caused by cholesterol deposits called plaques that cause inflammation and narrowing of . Lipids combine with proteins to form lipoproteins. Nicotine in tobacco smoke causes catecholamine (i.e., epinephrine, norepinephrine) release. These changes can appear in the coronary arteries by age 30 and increase with age. The endothelium (the inner lining of the vessel wall) is normally nonreactive to platelets and leukocytes, as well as coagulation, fibrinolytic, and complement factors. Tobacco use By removing LDLs from the bloodstream, the LDL receptors play a critical role in regulating cholesterol levels. Studies now are focusing on specific psychologic risk factors thought to increase risk of CAD. Coronary heart disease (CHD) develops slowly over time and the symptoms can be different for everyone. Prefers coronary arteries. Decreased cardiac output (which may occur during ischemic myocardial episode) stimulates sympathetic and parasympathetic nervous system, causing a variety of vague sensations that patient may not identify as related to anginal episode. Nursing Management: Renal and Urologic Problems, Nursing Management: Visual and Auditory Problems, Nursing Management: Obstructive Pulmonary Diseases, Nursing Management: Peripheral Nerve and Spinal Cord Problems, Nursing Management: Shock, Systemic Inflammatory Response Syndrome, and Multiple Organ Dysfunction Syndrome, Medical-Surgical Nursing Assessment and Management of Clinical P, Component of chylomicrons and HDL. Some people don't know they have CHD before they have a heart attack. Management of diabetes should include lifestyle changes and drug therapy to achieve a glycosylated hemoglobin (A1C or Hb A1C) level of less than 7%.6, Metabolic syndrome refers to a cluster of risk factors for CAD whose underlying pathophysiology may be related to insulin resistance. • Treatment strategies include low-fat diet, exercise, and lipid-lowering medications. The Framingham study provided early evidence that certain behaviors and lifestyles contribute to the development of CAD. The second major risk factor in CAD is hypertension, which is defined as a BP greater than 140/90 mm Hg or greater than 130/80 mm Hg if the patient has diabetes or chronic kidney disease.8 Hypertension increases the risk of death from CAD 10-fold in all people. Coronary Artery Disease Pathophysiology. After age 65, the incidence in men and women equalizes, although cardiovascular disease causes more deaths in women than men. hin.nhlbi.nih.gov/atpiii/calculator.asp?usertype=prof. Actual nursing diagnosis for activity. Nicotine in tobacco smoke causes catecholamine (i.e., epinephrine, norepinephrine) release. Pathophysiology. • Heterozygotes: 1 in 500 Diabetic patients also have alterations in lipid metabolism and tend to have high cholesterol and triglyceride levels. coronary revascularization, p. 745 In the Framingham study (one of the most widely known), men and women were observed for 20 years. One type of behavior, referred to as type A, includes perfectionism and a hardworking, driven personality. The incidence of CAD is two to four times greater among persons who have diabetes, even those with well-controlled blood glucose levels, than the general population. Several types of apolipoproteins exist (e.g., apo A-I, apo B-100, apo C-I). Found inside – Page 303For coronary artery disease, compare nonmodifiable risk factors with factors that are ... Compare the etiology and pathophysiology, clinical manifestations, ... In general, individuals with no or only one risk factor are considered at low risk for the development of CAD, and the LDL goal is less than 160 mg/dL (4.14 mmol/L). In general, HDL levels are higher in women, decrease with age, and are low in persons with CAD. It is the most common of the cardiovascular diseases. • Mortality rates from CAD have fallen more rapidly for men than women. Coronary Artery Disease and Acute Coronary Syndrome A third major risk factor in CAD is tobacco use. Genetics in Clinical Practice Psychosocial risk factors (e.g., depression, hostility, anger, stress) Native Americans Guidelines for treating elevated LDL cholesterol are based on a person’s 10-year risk for having a nonfatal MI or dying from a coronary event and his or her LDL levels. The thrombus may adhere to the wall of the artery, leading to further narrowing or total occlusion of the artery.

This decreases the amount of blood that goes to the heart muscle, which leads to chest pain (angina). Peripheral arterial disease is atherosclerosis that develops in the arteries of the legs or, less commonly, the arms. Involved in formation of VLDL, LDL, IDL, and chylomicrons White, middle-aged men have the highest incidence of coronary artery disease (CAD). Coronary artery disease (CAD) is a condition that impairs and reduces blood flow through your coronary arteries. View 481635 Coronary Artery Disease.doc from BUS 100 at San Francisco State University. Etiology & Pathophysiology. 34-4, available on the website for this chapter). Three or more of these risk factors meet the criteria for metabolic syndrome (as defined by the National Cholesterol Education Program Adult Treatment Panel III). Function of Protein Product At this stage the plaque is referred to as a, CAD, and women are more likely to have co-morbidities (e.g., hypertension, diabetes). Coronary artery disease (CAD), also called coronary heart disease (CHD), ischemic heart disease (IHD), or simply heart disease, involves the reduction of blood flow to the heart muscle due to build-up of plaque (atherosclerosis) in the arteries of the heart. And this is where the coronary arteries take in charge. These changes can appear in the coronary arteries by age 30 and increase with age. Vessel diameter is inversely related to risk of restenosis after interventions. Vessel diameter is inversely related to risk of restenosis after interventions. After menopause, women’s HDL2 levels decrease and quickly near those of men. • Exists in both heterozygous (most common) and homozygous forms. Women experience more “silent” MIs compared with men. Assessment: Often have HTN, Elevated Lipids/cholesterol, may have elevated glucose. Although the mortality rate from MI has decreased because of advances in treatment, it remains the leading cause of death from all cardiovascular diseases and other conditions in general.1 CAD mortality rates drop to those of nonsmokers within 12 months. Adherence to the self-care program. Exercise may also encourage the development of collateral circulation in the heart. • Plasma levels of LDLs elevated throughout life. The risk of developing CAD is two to six times higher in those who smoke tobacco or use smokeless tobacco than in those who do not. Apolipoprotein C-II Obesity: Waist circumference ≥102 cm (≥40 in) in men and ≥88 cm (≥35 in) in women* Coronary artery disease (CAD) is the world-wide leading cause of death not only in high-income countries but also increasingly in developing countries. Those at very high risk have CAD and multiple risk factors. Blood pressure is classified as (1) normal (BP less than 120/80 mm Hg), (2). When occlusion of the coronary arteries occurs slowly over a long period, there is a greater chance of adequate collateral circulation developing, and the myocardium may still receive an adequate amount of blood and oxygen. These interrelated risk factors of metabolic origin appear to promote the development of CAD. 34-2 Vessel occlusion with collateral circulation. Coronary artery disease is one of the major categories of heart disease in which cholesterol is deposited in the walls of arteries, called plaques. 1p Angina is the term used to describe the most common symptoms of CHD. This concise clinical companion to the thirteenth edition of Brunner and Suddarth's Textbook of Medical-Surgical Nursing presents nearly 200 diseases and disorders in alphabetical format, allowing rapid access to need-to-know information on ... Comprehensive nursing management of coronary artery disease. Ligand for LDL receptor Although it can be life-threatening, it can also be treated through surgery, medications, and lifestyle changes. Most common form of heart disease. • LDL cholesterol >160 mg/dL Once a woman reaches menopause, her risk for an MI quadruples. Congenital coronary artery anomalies are rare but well-described causes of chest pain and, in some cases, link to sudden cardiac death. These include depression, acute and chronic stress (e.g., poverty, serving as a caregiver), anxiety, hostility and anger, and lack of social support.10,11 In particular, depression is a risk factor for both the development and worsening of CAD. Thrombosis is also the major initiating factor in unstable angina, particularly when rest pain . Gene Decreases myocardial workload associated with work of digestion, reducing risk of anginal attack. sudden cardiac death (SCD), p. 762 The terms arteriosclerotic heart disease, cardiovascular heart disease, ischemic heart disease, coronary heart disease, and CAD all describe this disease process. Individual and group counseling sessions, nicotine replacement therapy, smoking cessation medications (e.g., bupropion [Zyban], varenicline [Chantix]), and hypnosis are examples of smoking cessation strategies. Risk factors are characteristics or conditions that are associated with a high incidence of a disease. Reduces frequency and severity of attack by producing continuous vasodilation. There is also some indication that carbon monoxide is a chemical irritant and causes injury to the endothelium. BMI is a measure of body fat based on height and weight. In the Framingham study (one of the most widely known), men and women were observed for 20 years. 19p Normally the endothelium repairs itself immediately. • Initial cardiac event for men is more often Ml than angina. 34-1, C). There is also evidence that people who tend to store fat in the abdomen (an “apple” figure) rather than in the hips and buttocks (a “pear” figure) have a higher incidence of CAD (see Table 41-2). The stages of development in atherosclerosis are (1) fatty streak, (2) fibrous plaque, and (3) complicated lesion. After menopause LDL levels increase. Familial Hypercholesterolemia This increased workload results in left ventricular hypertrophy and decreased stroke volume with each contraction. Atherosclerosis, in turn, causes narrowed, thickened arterial walls and decreases the distensibility and elasticity of vessels. Diabetes virtually eliminates the lower incidence of CAD in premenopausal women. Assess and document patient response to medication. Xanthomas (fatty deposits under the surface of the skin) can occur (see eFig. Management of diabetes should include lifestyle changes and drug therapy to achieve a glycosylated hemoglobin (A1C or Hb A1C) level of less than 7%.6 A, Damaged endothelium. Comprehensive nursing management of coronary artery disease. Chapter 5 Radiation and percutaneous coronary intervention. Lippincott Williams & Wilkins is also an approved provider of continuing . • African American women have a higher incidence and death rate related to CAD than white women. Cardiovascular disease is the major cause of death in the United States. As plaque builds up, the blood vessels get narrower and narrower, until they become blocked. Physical inactivity is the fourth major modifiable risk factor. Prinzmetal’s angina, p. 742 • CAD is the leading cause of death for women, regardless of race or ethnicity. • Men present more frequently than women with an acute MI as the first manifestation of CAD. Genetic Testing Here, we describe a case of an anomalous course . After age 65, the incidence in men and women equalizes, although cardiovascular disease causes more deaths in women than men. They are categorized as nonmodifiable and modifiable (Table 34-1). Yet most women do not consider CAD their greatest health risk.4 (Cardiovascular disease mortality trends for both men and women are shown in eFig. Provider Number CEP 11749. Coronary artery disease (CAD) is the most common form of heart disease. • Develop severe atherosclerosis in early to middle years. When the coronary arteries are narrowed or blocked, oxygen-rich blood can’t reach the heart muscle. Helps differentiate this chest pain, and aids in evaluating possible progression to unstable angina. Contributing Modifiable Risk Factors For those individuals with CAD, regular physical activity reduces symptoms, improves functional capacity, and improves other risk factors such as insulin resistance and glucose intolerance. Differentiate the precipitating factors, clinical presentation, and collaborative care of patients who are at risk for or have experienced sudden cardiac death. SNS stimulation causes an increased release of catecholamines (i.e., epinephrine, norepinephrine). Lifestyle factors that can contribute to elevated triglycerides include high alcohol consumption, high intake of refined carbohydrates and simple sugars, and physical inactivity. 16q Coronary artery disease (CAD) is the narrowing of the coronary arteries - the blood vessels that supply oxygen and nutrients to the heart muscle. By removing LDLs from the bloodstream, the LDL receptors play a critical role in regulating cholesterol levels. collateral circulation, p. 732 Serum lipid profile can be used to measure total cholesterol, triglycerides, LDLs, and high-density lipoproteins (HDLs). The term atherosclerosis comes from two Greek words: athere, meaning “fatty mush,” and skleros, meaning “hard.” This combination implies that atherosclerosis begins as soft deposits of fat that harden with age. Blood pressure is classified as (1) normal (BP less than 120/80 mm Hg), (2) prehypertension (BP of 120 to 139/80 to 89 mm Hg), (3) stage 1 hypertension (140 to 159/90 to 99 mm Hg), and (4) stage 2 hypertension (BP greater than 160/100 mm Hg).8 The cause of hypertension in 90% of those affected is unknown, but it is usually controllable with diet and/or drugs. The level of CRP rises when there is systemic inflammation. Activation of the exposed platelets causes expression of glycoprotein Ilb/IIIa receptors that bind fibrinogen. Lives can be extended and improved when these diseases are prevented, detected, and managed. This volume summarizes current knowledge and presents evidence-based interventions that are effective, cost-effective, and scalable in LMICs. (See Chapter 11, Tables 11-4 through 11-6 for information on smoking cessation.). Coronary Artery Disease Pathophysiology. Without quick treatment, a heart attack can lead to serious problems and even death. Also, stress-induced mechanisms can cause elevated lipid and glucose levels and changes in blood coagulation, which can lead to increased atherogenesis. Cardiac pain may radiate. Angina There is no medical term for chest pain Flutter Arrhythmia. (See Chapter 33 for a complete discussion of hypertension.). Found inside – Page 184Explain the treatment of selected cardiovascular • Describe the etiology and pathophysiology of atherosclerotic coronary artery disease. The borders can be smooth or irregular with rough, jagged edges. Goldie Hawn This leads to restrictive blood supply to the heart muscle which leads to chest pain (stable or unstable angina) to myocardial infraction (MI). Activation of the exposed platelets causes expression of glycoprotein Ilb/IIIa receptors that bind fibrinogen. • HDL cholesterol <40 mg/dL in men or <50 mg/dL in women* • Autosomal dominant disorder. Similar to coronary artery and cerebrovascular disease, the development of an atherosclerotic plaque that narrows or completely occludes an artery is the number one cause of peripheral . Coronary artery disease. The following information generates a risk score: (1) age, (2) gender, (3) use of tobacco, (4) systolic BP, (5) use of BP medications, (6) total cholesterol, and (7) HDL cholesterol level.7 A 10-year risk calculator is available at hin.nhlbi.nih.gov/atpiii/calculator.asp?usertype=prof. Vessel occlusion with collateral circulation. Coronary artery bypass grafting (CABG) is a procedure to improve poor blood flow to the heart. The increased risk for CAD is proportional to the degree of obesity. The term atherosclerosis comes from two Greek words: athere, meaning “fatty mush,” and skleros, meaning “hard.” This combination implies that atherosclerosis begins as soft deposits of fat that harden with age. artery’s inner wall is compromised, platelets accumulate in large numbers, leading to a thrombus. Fatty streaks, the earliest lesions of atherosclerosis, are characterized by lipid-filled smooth muscle cells. Anatomical thresholds for CAD severity vary. Two factors contribute to the growth and extent of collateral circulation: (1) the inherited predisposition to develop new blood vessels (angiogenesis) and (2) the presence of chronic ischemia. This does not happen in the individual with CAD. The American Heart Association (AHA) estimates that 1.1 million Americans have an MI each year. Further, tobacco smoking decreases estrogen levels, placing premenopausal women at greater risk for CAD. In a coronary embolism, pieces of a clot from another site break off and can travel into a coronary artery, occluding it. Coronary artery disease (CAD) occurs when the arteries that bring blood to the heart muscle (coronary arteries) become hardened and narrowed. This narrows or blocks the artery and can cause a heart attack because blood flow cannot reach the heart muscle. Coronary heart disease or coronary artery disease occurs when the major blood vessels that supply your heart with blood, oxygen and nutrients become damaged or diseased. 19q These changes increase the cardiac workload. The type A person often suppresses anger and hostility, has a sense of time urgency, is impatient, and creates stress and tension. Physical inactivity implies a lack of adequate physical exercise on a regular basis. Facilitates gas exchange to decrease hypoxia and resultant shortness of breath. The stress of an elevated BP increases the rate of atherosclerotic development. • Men receive more evidence-based therapies (e.g., aspirin, statins, diagnostic catheterization, PCI) when acutely ill from CAD (e.g., MI) than women. The mechanism by which physical inactivity predisposes a person to CAD is mostly still unknown. The incidence of CAD is two to four times greater among persons who have diabetes, even those with well-controlled blood glucose levels, than the general population. Ethnicity (more common in whites than in African Americans) Potent narcotic analgesic may be used in acute onset because of its several beneficial effects, e.g., causes peripheral vasodilation and reduces myocardial workload; has a sedative effect to produce relaxation; interrupts the flow of vasoconstricting catecholamines and thereby effectively relieves severe chest pain. I have witnessed the softening of the hardest of hearts by a simple smile. Guidelines for treating elevated LDL cholesterol are based on a person’s 10-year risk for having a nonfatal MI or dying from a coronary event and his or her LDL levels. You may also like the following posts and care plans: Nursing care plans about the different diseases of the cardiovascular system: Thanks for extremely user friendly information. *Three or more of these risk factors meet the criteria for metabolic syndrome (as defined by the National Cholesterol Education Program Adult Treatment Panel III). There is also some indication that carbon monoxide is a chemical irritant and causes injury to the endothelium. People with insulin resistance often have this pattern. Women report more disability after a cardiac event than men. The final stage in the development of the atherosclerotic lesion is the most dangerous. The type A person often suppresses anger and hostility, has a sense of time urgency, is impatient, and creates stress and tension. The Social Security Administration (SSA) uses a screening tool called the Listing of Impairments to identify claimants who are so severely impaired that they cannot work at all and thus immediately qualify for benefits. The mechanism by which physical inactivity predisposes a person to CAD is mostly still unknown. Diabetes virtually eliminates the lower incidence of CAD in premenopausal women. In general, individuals with no or only one risk factor are considered at low risk for the development of CAD, and the LDL goal is less than 160 mg/dL (4.14 mmol/L). Consequently, a diminished blood flow results in a more severe ischemia or infarction. When a plaque occludes the normal flow of blood through a coronary artery and the resulting ischemia is chronic, increased collateral circulation develops (Fig. From: Jorde LB, Carey JC, Bamshad MJ: Medical genetics, ed 4, Philadelphia, 2010, Mosby. Elevate head of bed if patient is short of breath. Physically active people, The mortality rate from CAD is statistically higher in obese persons. All authors. This, in turn, leads to further platelet aggregation and adhesion, further enlarging the thrombus. This can cause angina or a heart attack. Hispanics have lower rates of CAD than either non-Hispanic whites or African Americans. Elevated Serum Lipids. Men present more frequently than women with an acute MI as the first manifestation of CAD. Provide supplemental oxygen as indicated. Actual nursing diagnosis for acute. Treatment strategies include low-fat diet, exercise, and lipid-lowering medications. If headache is intolerable, alteration of dose or discontinuation of drug may be necessary. Review. 34-1, B). Among those who have an MI, women are more likely to suffer a fatal cardiac event within 1 yr than men. Spontaneous coronary artery dissection (SCAD) is an uncommon occurrence, but because it occurs spontaneously, it's important to recognize the symptoms and get treatment immediately. RISK FACTORS FOR CORONARY ARTERY DISEASE However, nicotine is highly addictive, and often intensive intervention is required to assist people to quit. This is thought to be related to the protective effects of natural estrogen. In postmenopausal women, hypertension is associated with a higher incidence of CAD than in men and premenopausal women. Coronary heart disease, also called coronary artery disease, is a chronic (long-lasting) disease and affects the blood vessels that supply blood to your heart. In addition, there is an increase in insulin resistance in obese individuals. Found inside – Page 463Illustrate the pathophysiology of coronary artery disease. 3. Outline nursing interventions to care for a patient experiencing angina, including medication ... HDL, High-density lipoprotein; IDL, intermediate-density lipoprotein; LCAT, lecithin cholesterol acyltransferase; LDL, low-density lipoprotein; VLDL, very-low-density lipoprotein. Major Modifiable Risk Factors Coronary heart disease, or coronary artery disease (CAD), is characterized by inflammation and the buildup of and fatty deposits along the innermost layer of the coronary arteries. Carbon monoxide, a byproduct of combustion found in tobacco smoke, affects the oxygen-carrying capacity of hemoglobin by reducing the sites available for oxygen transport. Carbon monoxide, a byproduct of combustion found in tobacco smoke, affects the oxygen-carrying capacity of hemoglobin by reducing the sites available for oxygen transport.
